What are upright freezers and how do they work?

This type of household appliance is designed to keep different foods in a frozen state. It is generally purchased to complement a refrigerator. Upright freezers are most frequently used by families that want or need to store larger quantities of food at home.

What a freezer does is removing heat from the food until it freezes. This is achieved by using a gaseous refrigerant that circulates through different components of the household appliance.

Are upright or chest freezers better?

You’re probably wondering whether you should opt for an upright freezer or a chest one. The truth is that these products are not significantly different, which is why your decision might be difficult. Here’s a quick explanation of their main characteristics to help you dispel any doubt you might have:

  • Chest freezer: The main difference is that you access the food from the top. They offer a large storage capacity, but it might be difficult to reach products placed at the bottom. One advantage is that you can freeze large foods. It consumes less energy than upright freezers.
  • Upright freezer: You’ll access your food more easily. The larger models offer the same space as chest freezers. Note that they are generally more expensive. They take up less space and can be placed in the kitchen.

Are upright freezers or American fridges better?

You may also end up asking yourself whether you should buy a vertical freezer or an American-style fridge freezer. First of all, keep in mind that an American fridge doesn’t offer the same freezing space as a large upright freezer. This means that these appliances don’t actually provide the same storage solution. One advantage of American fridges is that you can quickly store food in it (even if it’s still in a pot). In freezers, you should always store cold food in plastic containers or bags.

You’ll also need to have significant space in your kitchen if you opt for a double-door fridge. Most kitchens are designed to house standard refrigerators. the advantage of upright freezers is that they can be placed elsewhere in the kitchen, or even in other rooms. You should also know that American fridges are quite expensive appliances.

Compressor It’s designed to increase the gas pressure from the evaporator, and then compress it. The compressor then turns it back to a liquid state so it can circulate through the freezer.
Expansion valve Its role is to bring enough refrigerant to the evaporator depending on its needs. It needs to reduce the pressure and temperature of the liquid to achieve this.
Coils The refrigerant liquid circulates through these coiled capillary tubes. They are used as the link between the compressor and the expansion valve.
Thermostat This elements is in charge of maintaining the right temperature in the freezer. Once the temperature is suitable, the thermostat and the refrigerant path stop until the temperature rises again.
Refrigerant It is used to cool the freezer. Two liquids are used: Freon and ammonia. Both of these substances are very dangerous, and you should never directly handle them.

Shopping Criteria

It’s almost time to wrap up our shopping guide, but we count possibly let you go with introducing you to the most important aspects that you’ll have to consider when buying your upright freezer. These shopping criteria will undoubtedly help you choose the model that best fits your needs. These factors are the following:

  • Size
  • Energy consumption
  • Freezing technologies
  • Reversible doors
  • Supercooling


This could potentially be the most important criterion for you. As we mentioned earlier, you can find two types of upright freezers. Some models are designed to be placed under the countertop and measure around 80 centimetres in height. The other models measure approximately 180 centimetres, a size similar to that of standard fridges.

In terms of storage space, the second option is naturally the more advantageous one. However, keep in mind that models of this size are less easy to place in your kitchen. If you have a lot of free space, we encourage you to opt for these models. These are also more suitable for larger families, or if you’re used to buying large quantities of food at a time.

Energy consumption

The energy consumption of your freezer is another key aspect. Simply remember that a freezer cannot stop working like other types of appliances. Their energy ratings range between A+ and A+++, with the most efficient ones having a A+++ classification. Opt for this option and you’ll be saving on your electricity bills.

Freezing technologies

We’ve already talked about the three different types of freezing technologies. In that regard, you are encouraged to go for no frost models, as you won’t have any ice building up inside your upright freezer. This will prevent you from having to defrost it, making it much easier to clean. Keep this in mind when you purchase your appliance.

Reversible doors

Reversible doors are particularly useful features for your upright freezer. They will allow you to place the appliance anywhere you like in the kitchen. If you eventually decide to change its location, you won’t have any problem doing so. You might regret it later on if you don’t buy a model with a reversible door.


Also called undercooling, this system allows the food to freeze quickly. Freezers with this feature are much more efficient than those who don’t. It is particularly useful to better preserve the properties of the frozen food. That way, it will lose fewer nutrients, such as vitamins or minerals. This is definitely an interesting function to have.


Upright freezers give you extra storage space, whether you buy frozen food or want to freeze food you’ve prepared. Remember that the size is a key criteria to consider when making your purchase: it needs to be right for your family. You should also evaluate its energy consumption to avoid overspending.

The freezing technique of your model is another aspect you shouldn’t overlook. As you know, no frost is the most efficient, as it prevents ice from forming and makes it easier for you to clean the freezer. Quick freezing technology is also very useful to better preserve the food’s nutrients. Finally, you should always try to get the best value for money possible.
