Collage of various types of freezers.

Quick List: Types of Freezers

  1. Chest
  2. Upright
  3. Drawer
  4. Portable
  5. Display

When we moved to our current house, our oldest son was three and son number two was just about to be born. We moved because we needed a larger house, which included space for a chest freezer.

As soon as we got the keys, we ordered a small chest freezer and put it in the garage. It was like a huge luxury.

But guess what? We should have ordered a bigger one. Keep that in mind – if you’re getting a standalone freezer, get a big one. You won’t regret it.

A freezer is an appliance that stores and preserves food at very low temperatures. Sometimes, it is a separate compartment that is attached to a refrigerator and at times, it is a separate appliance altogether.

The freezer is one of the most commonly used appliances, both domestically and commercially. A freezer is essential for keeping foods preserved for a long time. It keeps the food at extremely low temperatures which ensures that the food is protected from any microbial contamination and damage.

The mechanism by which a freezer works is quite simple. A little knowledge about its components and working can help you fix the problems that may arise from time to time. Also, understanding the appliance’s functions can also help you maintain it better.

What is Refrigerant?

The refrigerant is a compound which is usually found in the gaseous state. It absorbs heat produced during the refrigeration process readily and provides cooling necessary for freezing.

Without refrigerant, there would be no freezing. After the refrigerant absorbs heat, it converts into a high-pressure liquid from a low-pressure gas.

The most common refrigerants used are:

  • CFCs (Chlorofluorocarbons), including R12: They contributed greatly to the greenhouse effect. New stocks of CFCs have not been produced since 1994.
  • HCFCs (Hydrochlorofluorocarbons), including R22: HCFCs are less damaging to the ozone as compared to CFCs. HCFCs were completely phased out by 2020 as a result of the Clean Air Act.
  • Hydrofluorocarbons (HFCs), including R410A and R134: They do not contain any chlorine. Hence, they are safer for the environment. HFCs are now used in place of R22.

Freezer Parts

A freezer is composed of different components that form a freezing system. This system is responsible for the freezing effect. The major parts of a freezer are as following:

1. Freezer Compressor

The compressor is a reciprocating pump that is hermetically sealed. A compressor is the heart of the entire refrigeration system. It is responsible for pumping the refrigerant gas to all the parts of the freezer to keep the refrigeration cycle running repeatedly.

The sizes of compressor vary according to the load-bearing capacity of the freezer. The sizes range from 1/12 to 1 horsepower.

A compressor is enclosed in a steel casing. Inside the steel casing, there is an electric motor, piston, cylinder, crankshaft, intake, exhaust valves, connecting rod, and a ceramic terminal block. A small quantity of Capilla oil is also present within.

2. Freezer Condenser

Condensers are the heat exchangers of freezers. The condenser is made of coiled serpentine copper with aluminum fins. It is located at the rear end of a freezer.

The purpose of a condenser in a freezer is to remove all the heat that is supplied to the refrigerant in the evaporator and the heat produced in the compressor during compression. It also condenses the vapors of the refrigerant into a liquid.

Condensing units are of various types.

  • Evaporating Type: In an evaporative type of condenser, the coil assembly is housed within a steel casing. Air is forced through the coils and discharged on top of the unit.
  • Air-Cooled Type: In an air-cooled type of condenser, the coils are housed within a steel casing that is open at the top and bottom. The cooling of coils is done by natural air.
  • Water-Cooled Type: In this type of condenser, the water enters into the cylinder in which coils are enclosed. The water circulates inside the coils and discharged through the outlet pipe.

A further classification of condensers is as below:

  • Finned-Static Type: In this type of condenser, the coils are held together with the help of very thin fins which provide more area for the transmission of heat into the atmosphere.
  • Plate-Static Type: In plate-static type condensers, the coils are sandwiched inside a rectangular steel box.
  • Wire-Static Type: For this type of condenser, the coils are held in place by straight steel wires that form a rectangular shape.
  • Convection Type: the coils are enclosed in a steel box in this type of condenser. The air is forced through the coils with the help of an attached fan.
  • Finned-Forced Convection Type: It is a convection type of condenser with a fan that cools coils.

3. Freezer Filter/Dryer

This component of a freezer is responsible to filter any iron particles, moisture, and dirt from the refrigerant and keep them from entering the refrigeration system. If left unfiltered, the flow of refrigerant into the expansion valve will be restricted.

Some filters/dryers fried contain a moisture absorbent material like silica gel that absorbs any moisture that may be present in the refrigerant. The filter/dryer is responsible for protecting the compressor by filtering or restricting any impurities or moisture content that may have contaminated the refrigerant.

Freezer filter types:

  • Flare Tube Connection: They may become loose over time due to the constant vibrations in the refrigeration system and cause a refrigerant leakage problem.
  • Brazing Connection: Refrigerant leakage in this type of filter is less likely to occur as the joints are brazed.

4. Expansion Valve

Expansion valve or capillary tube made of copper is another common component of a refrigeration system. It controls the flow of refrigerant through the system. High-pressure liquid refrigerant enters the expansion valve and leaves as low pressure, low-temperature liquid refrigerant.

It is necessary that the refrigerant is converted into low-pressure refrigerant before entering the evaporator. When it absorbs heat, it is converted into gas.

A compressor allows only gas refrigerant to enter since gases can be compressed and liquids cannot be compressed. The outer diameter of an expansion valve is 2.5mm and the length is usually between eight to 12 feet.

There are five different types of expansion valves:

  • Capillary Tube Type: This type is made up of small copper tubing. Having a hole with diameter from 1mm to 3mm. it serves as a consistent limiting valve for the flow of refrigerant from the condenser to the evaporator.
  • Automatic Expansion Type: This type of expansion valve controls the flow of refrigerant by a simple mechanism of opening and closing of a control valve for low pressure. The refrigerant is sprayed into the evaporator.
  • Thermostatic Expansion Type: This type of expansion valve controls the refrigerant flow by sending signals to a sensing bulb which is attached to an outlet of the evaporator. This sensing bulb sends instructions to the valve for opening and closing.
  • Low-Side Float Expansion Type: The valve is controlled by a finned cooling coil. A constant level of refrigerant is maintained in the evaporator.
  • High-Side Float Expansion Type: It is the same as the low-side float expansion type. The only difference is that it keeps the evaporated completely flooded with liquid refrigerant.

5. Evaporator

The evaporator is a serpentine aluminum tube component with aluminum fins. It is responsible for absorbing heat in the freezing compartments and transferring it all to the condenser. After the low-pressure liquid refrigerant absorbs this heat, it becomes gas.

This refrigerant vapor makes its journey to the compressor, through the accumulator.

6. Accumulator

An accumulator collects refrigerant. It behaves as a refrigerant tank ensuring that the evaporator does not run out of it. If there is no accumulator, symptoms of refrigerant starvation will become visible.

7. Fan Motor

The main purpose of a freezer fan motor is to keep the compressor cool. It is situated in the compressor room, just beside the compressor. It is composed of a steel bracket and a stand and is found bolted into a cross member.

The fan runs with the compressor. If the aluminum blade of a fan is bent during maintenance, it can vibrate quite furiously which is detrimental to the shaft bearings. This can cause an early breakdown of the freezer.

If any component of a freezer is not working properly, they would not provide the cooling and would cause defrosting.

How Do Freezers Work?

A chest freezer with two compartments

The mechanism by which a freezer works revolves around drawing heat out from the freezing compartment. At the start of the process, the gaseous refrigerant goes into the compressor where the refrigerant is compressed.

The temperature of the gas at this point is very high. As the hot gaseous refrigerant moves through various coils in the freezing system, it loses its heat and starts to cool off.

As the gaseous refrigerant is cooled to a very low temperature, it is liquefied. It is then forced into the expansion valve which converts the liquid refrigerant into a cold mist by forcing it through its extremely small opening.

The cold mist moves through the system through more and more coils. It starts evaporating and comes back in a gaseous state as it absorbs heat along the way.

At this point, the temperature of the mist is -27 degrees. It takes the heat of the freezing compartment with it, hence turning back into the gas form.

When the refrigerant becomes gas again, it gets moved to the compressor again where it is compressed and the process is repeated. The process continues until the refrigerant has taken away all the heat from the freezing compartment, leaving behind none. This is what causes the food in a freezer to freeze.

Different Types of Freezers

There are five types of freezers available. You can choose the type that suits your requirements.

1. Chest Freezers

A single lid chest freezer

Chest freezers are also called reach-in freezers. They are the most common types of freezers that are used commercially. They are economical and spacious.

The interior and exterior are shaped like a large box that gives it amazing storage capacity. Chest freezers have hinged lids that open upwards and are easy to use.

A drawback of chest freezers is that their large size requires a lot of space. Also, these freezers do not have a fan which results in an inconsistent temperature.

The bottom area of the freezer is cooler as cold air is heavier. Therefore, meats are usually stored in lower parts. An additional feature of baskets in the freezer helps with better organization and easy access to stored items.

The capacity of chest freezers ranges from 2.1 cubic feet to 40 cubic feet. Because of its exceptionally large storage capacity, they are used commercially in hotels, restaurants, and other large-scale businesses for storing bulk foods.

2. Upright Freezers

Upright freezers are of three main types:

  • Stand-alone
  • Stacked fridge freezer – with freezer above or below the refrigerator
  • American-style side-by-side freezer

a. Stand-Alone Upright Freezer

An upright freezer costs twice as much as the chest freezer. However, an upright freezer is worth the money. Unlike chest freezers, the upright freezers have more height and they cover less floor space.

This makes them suitable for domestic use. Because of their vertical design, they allow easy access to stored items. Most of the items are at an eye level. The compartments in an upright freeze are stacked which is another reason why the stored items are easier to access and retrieve.

Drawer freezers are beneficial for both catering and home use. They keep the items highly organized. You can access the food items easily.

A major drawback of drawer freezers is their price. They are very expensive and cannot substitute for a full-size freezer.

The best thing about drawer freezers at home is that children and disabled people who use a wheelchair can access them easily.

4. Portable Freezers

Portable freezes have a limited storage capacity. They are made to store only a limited number of items while you are traveling or if you wish to transfer any food items that should stay frozen. They are perfect for small offices and can be placed in any corner of your room, as they do not occupy a lot of space.

5. Display Freezers

Display freezers are a type of upright freezers that have glass displays. They are mostly used in shops and supermarkets where people need to have a clear look at all the items.

They are available in numerous sizes. Different businesses prefer different sizes.

You can get an upright display freezer such as the following:

Best Freezer Brands

1. Chest

A chest freezer usually sits on the floor, is square or rectangle shaped and has a lid that hinges up.

“In general, a chest freezer offers more usable space and saves more energy than an upright freezer. This type also maintains its temperature better even when open, as cold air sinks to the bottom of the unit,” says Maddy Sweitzer-Lammé.

The only issue I have ever had with a chest freezer is how hard it is to organize. I usually would place items in different boxes or bins to keep the items as separate as possible. They do, however, provide an even distribution of freezing for all food items.

Top Chest Freezer Brands

One top brand is the Midea Chest Freezer, which offers 3.5, 5 or 7 cubic feet of space. Otherwise, you might appreciate the Arctic King, which I personally could use because it’s big enough for “just me.” Designed for small spaces the freezers costs about three times less than full-size models.

2. Portable

I think one of the most amazing inventions ever is the portable freezer. You can take them just about anywhere. They also have far more room than an upright refrigerator usually provides for frozen storage.

The portable freezer usually has both a car charging adapter and a wall plug. I’m considering getting one because I can then make ice or freeze cold packs for my other freezers on the go if I want to.

Top Portable Brands

You don’t always have to buy the most expensive appliance for the best performance. If you’re short on funds, I say start with one that will last you at least a couple of years.

A top discount portable freezer brand is the HCalory 35L capacity refrigerator and freezer. You might want one that offers more freezing space, however. If so, you may need to spend at least twice as much as it would cost for the HCalory, but not always.

One of the highest end portable freezers you can find is the ARB Fridge Freezer. It has 50 quarts (47 liters) of space in it.

Keep in mind one fact about portable freezers: They do require that you have a continuous supply of power to keep them running. Also, you may want to find the smallest upright or chest freezer (five cubic feet or smaller) instead of a portable fridge/freezer if you’re looking for just freezer space.

Mini Upright Versus Portable Freezer

A mini upright freezer doesn’t usually have a portable cord for car charging, so you will have to supply external power for traveling.

However, it will provide you with more freezer space than a portable freezer made with both a refrigerator and a freezer. 

3. Drawer

You might have seen stainless steel freezers with drawers in them used for frozen items. I like the concept because it keeps items organized easier than when putting items in a chest freezer.

Drawer freezer designs also have become more creative and can even be part of kitchen cabinets. You may even see them hidden behind kitchen cabinets.

Top Drawer Freezer Brands

Summit SCFF532D Drawer Freezer, Stainless-Steel

Sub-zero drawer freezers seem to have cornered the market on built-in cabinet freezers. You can design your kitchen to have them placed under the counter or on one side or the other near an upright fridge.

Upright KitchenAid, GE, LG and Whirlpool also have drawer freezers built into them. For drawer freezers, they do cool food quickly but not always as evenly as a chest freezer.

4. Upright

An upright freezer has shelves and storage space in it and stands up likean upright refrigerator. It also usually has a hinged door that opens out instead of upward.

It’s much easier to organize your food in an upright than in a chest freezer. Your back muscles may appreciate it, too. That’s because you won’t have to bend as much when accessing food from it. Uprights also seem to fit in easier with kitchen cabinet displays.

Top Upright Brands

Frigidaire, LG, Insignia and GE all make full-length upright freezers. 

5. Mini Upright

Upright freezers come in sizes as small as 3.5 cubic feet, which is ideal for space saving. Keep in mind, however, that the dimensions of an item this small is only 12x12x12 inches. For that reason, I probably would get the five cubic feet one for portable use.

Top Mini Upright Brands

Midea MRC04M3AWW, White 3.5 cu. ft. Mini Freezer, Cubic Feet

Arctic King is one of the top brands of economically priced freezers. Other top vendors include Upstreman, Stakol and LifePlus.

Difference between Freezing and Deep Freezing

Freezing and deep freezing are two entirely different things. Although they both involve the freezing of food, there is a major difference between the two.


Freezing involves a slow decrease in temperature. It may take up to 24 hours to freeze a food item completely. The water that is contained in the food is converted into large ice crystals. Many individuals use this technique to keep their food frozen.

A major disadvantage of freezing is that the food items being frozen may get dry and damaged. Since the crystals are large, they may end up perforating the cell walls of the food items. Aroma and parts of water may escape the food.

Deep Freezing

Deep freezing involves a rapid decrease in temperature. It is an industrial technique that freezes the foods at extremely low temperatures. It takes only a few minutes to one hour to completely freeze the food items. In this technique, food is exposed to extremely low temperatures, usually -30 to -50oC.

It causes the core temperature of the product to reach as low as -18oC. As a result, the water that is present in the food is finely crystallized. The proliferation of microorganism and killing of cells is limited. The products that are frozen by this technique retain their freshness and flavor because the cells become dormant.

Unusual Uses of Freezers

Apart from storing foods and beverages, freezers can be used for various purposes which you might have not thought about before. Below are some unusual yet interesting uses of a freezer:

  • If you have bought a shoe that is a bit snug for you, a freezer can help you make it your size. Fill a sealable plastic bag with water and place it your shoe. Put the shoe with the plastic bag in the freezer overnight. Your shoe will be stretched enough to make them fit you nicely. If you want to stretch it more, repeat the same procedure.
  • If you have bubblegum stuck to the sole of your shoe, you can get it off with the help of your freezer. Just place a piece of paper on the bubble gum and freeze the shoe for 1-2 hours. The bubblegum will come off easily.
  • You can keep the lipsticks in a freezer to keep them fresh. Cold temperatures are ideal for keeping lipsticks and a freezer is the absolute best option for this.
  • Before sharpening your eyeliner, place it in a freezer for 15 to 20 minutes. Sharpening the eyeliner after doing this will give you a perfectly pointed tip.
  • Keeping your candles in a freezer can increase their life. Their burning time can be increased up to two times.

Freezers are a must-have in today’s era. Every household has a freezer. Imagining life without one is just not possible now. Understanding how they work, the types of freezers that are available and the proper usage can help you keep your freezers maintained for a very long time.

Frequently Asked Questions

Below are answers to common questions about freezers.

How do freezers work?

Modern freezers keep foods frozen by combining the cabinet design with high-quality insulation materials and a process that uses electricity to run a freezing system that pulls heat from the freezer interior and replaces it with cool air.

Refrigerant, any gas that can absorb heat, cools air temperature via thermodynamic cycles that involve compression and evaporation. A freezer compressor condenses the gas until it becomes an incredibly hot liquid.

The liquid is forced through coils on the exterior of the unit and cools when exposed to ambient air temperature. The cooler liquid passes through an evaporator that allows it to rapidly mist and expands back into a gaseous state, which causes an automatic absorption of heat.

What is freezer burn?

Freezer burn appears as ice crystals on one or more spots on food coupled with a dried out, discolored and/or tough surface. A freezer burn spot typically looks brown, gray or white. The surface texture can feel grainy or rough to the touch.

With certain foods, the surface can become powdery or collapse when touched with a finger or object. Any food that has experienced freezer burn usually has an off odor. People can still eat it, but it usually tastes off and unpleasant.

How do you prevent freezer burn?

People should always remove as much air as possible from food packages via a vacuum seal or manual method. For example, a person might insert a straw into a freezer bag, seal the bag except for at the straw, suck out the air manually, pull out the straw and press the seal.

Double-wrapping foods with aluminum foil in addition to freezer paper or plastic wrap can also help. People should also repackage previously frozen foods that distributors failed to place in air-tight bags or boxes. Freezing certain foods in containers filled with water can also protect them from freezer burn.

What causes freezer burn?

Dehydration and oxygen exposure are the primary causes of freezer burn. When a person doesn’t seal food enough to remove air from a freezer bag or container or plastic wrap, water molecules dissipate and release into the open space around the food.

The water turns into ice that settles on the surface. Oxygen molecules seep into the spaces that previously held water and then degrade the food and adversely affect its color, smell and taste.

How cold should a freezer be?

A freezer must have a temperature of 0 degrees Fahrenheit or lower, depending on the specifications provided by the manufacturer of a specific model, to keep foods frozen to the point of preventing decay and spoilage.

A person should always check their freezer at least once a week with a thermometer designed specifically to make certain that the unit works properly.

Can freezers be too cold?

A freezer’s temperature should never go below the manufacturer’s recommended setting for a specific model. If a freezer thermometer shows a colder temperature and frost buildup, someone might have set the temperature too low or failed to manually defrost the freezer, when necessary, at least once a year.

In both manual and automatic defrost freezers, defective and broken parts can cause this problem. For example, a defective or broken defrost heater that fails to melt frost from the evaporator coils or a non-working evaporator fan can cause the temperature to drop too low.

Who, where and when was the freezer invented?

Before the advent of modern refrigeration and freezing of stored foods, people kept their food safe from immediate deterioration using a variety of methods, including caves, root cellars and in-ground holes and boxes filled with ice or snow and insulating materials like straw.

In 1802, American Thomas Moore then patented a design for a home insulated, cabinet-style icebox that featured an enclosed zone for food and a separate zone for ice that would keep the entire unit cool for approximately five to seven days.

Modern refrigerators and freezers use a similar cabinet design, but freeze via an artificial refrigeration process known as evaporative cooling that maintains temperatures slightly above or below the freezing point of water, respectively.

Several inventors have received credit for artificial refrigeration:

In 1748, a Scotsman named William Cullen provided the public with a demonstration of the evaporative cooling process.

In 1805, American Oliver Evans designed a vapor compression refrigeration system. In 1834, his co-worker, Jacob Perkins, built a prototype with liquid ammonia.

In 1844, American John Gorrie introduced a design based on Evans’ idea.

By 1876, liquifying gas for the evaporation process was patented by German Carl von Linden.

All of these discoveries and technical designs eventually resulted in American Nathaniel B. Wales inventing and patenting by 1914 an electric refrigeration unit for home use called the Kelvinator.

In the 1940s, consumer demand for improved longer food storage and greater cabinet storage capacity prompted manufacturers to create dual refrigerator and freezer units and standalone freezers known as deep freezes.

Are freezer bags recyclable?

Many of the freezer bags on the market, including sealable plastic food storage and freezer bags and prepackaged bags, are recyclable. People should always check the resin identification code located inside of the “three arrows triangle” symbol on their bags. Grocery and retail stores and municipal recyclers collect clean, recyclable bags.

People should also remove plastic zippers from zipper-style bags before recycling. Thankfully, these zippers are great for use in a variety of upcycle crafts. As for non-recyclable freezer bags: They’re designed for durability, which makes them perfect for other types of home and office storage.

Are freezer bags waterproof?

Many consumers believe that freezer bags are waterproof, but most companies only market these bags as “leak-resistant” because the designs can fail when their bags are submerged under water for a long time. It’s important to note that leakage can still happen with leak-resistant bags because of manufacturing defects and accidental damage.

Can freezer food go bad?

In a perfect freezer scenario, frozen food is safe to eat forever, as long as it’s always kept frozen at the right temperature. Freezer burn does occur with long-term storage. Frozen food also experiences harmful bacteria growth when temperatures fluctuate or rise above normal.

Temperature problems happen when a freezer isn’t full enough or someone leaves the door open too long and food defrosts. Other defrost events can occur if a freezer door seal or any other part of the system fails. During a power outage, a full, unopened freezer can maintain the right temperature for up to 48 hours.

Can a freezer be too full?

When a freezer is full, the frozen food reduces the work that the freezer must do to keep the interior cool. During a power outage, it also acts like ice in a cooler.

On the other hand, an overly full freezer with blocked vents restricts airflow and causes food to defrost in spots. The condenser also overworks. An overworked condenser increases an electric bill and eventually breaks.

What is freezer paper?

Freezer paper is merely standard, thick butcher-style paper altered slightly with a plastic, resin or wax coating on one side to prevent leakage when used to wrap meats and different foods that contain juices or other fluids.

Freezer paper works well for storage for up to a year. It’s perfect for exterior double-wrapping of plastic-wrapped meats. It’s also good for labeling purposes since the non-coated exterior surface is plain paper.

Where to buy a freezer online?

Anyone can find a freezer or refrigerator/freezer combo that fits their needs by running a simple online search using the keyword phrase “buy a freezer.”

Since shipping large appliances costs a lot of money, many shoppers buy through a local appliance, furniture or department store’s website to receive free or low-cost local delivery. Many e-commerce sites that offer subscription services include the cost of shipping in their monthly membership fees.

It’s critical that a person who finds a freezer model that they like compare reviews on multiple websites to learn about any model or merchant problems experienced by existing owners.

Why does ice build up in a freezer?

Frost happens when a freezer’s temperature fluctuates often or the freezer fails to maintain the appropriate overall temperature in spots. These temperature problems occur when a person opens the freezer door too much or the door hinges or seal don’t function per design specifications because of loose installation, detachment or poor alignment.

In these scenarios, outside warmer air enters the freezer and increases the temperature enough to form condensation on frozen food packages and freezer walls. The temperature eventually balances out enough to refreeze everything, but a cycle of defrost and freezing happens that causes ice layers to build up.

This problem can also occur when certain parts overheat, the drain clogs or the owner installs the freezer too close to a wall or fails to clean the coils and external vents.

What is a deep freezer?

A deep freezer is a stand-alone freezer. They usually come without shelves to maximize the storage space.

What is a chest freezer used for?

Chest freezers are used to freeze large quantities of food. You can find them in business settings or in homes with big families.
