Commercial refrigeration is highly useful for restaurants, department stores, and other business establishments. There are many different types of compressors used in commercial refrigerators including vapour compression and gas compression. Here is some information about these compressors and their benefits.
The most common types of compressors are rotary screw, scroll, and centrifugal. These applications are less noisy, highly efficient, and have no pressure issues. These compressors are often described as either semi-hermetic or open. In semi-hermetic compressors, the motor that drives the device is integrated and operated within the refrigerant system.
The other type of compressor is the vapour system which uses a circulating liquid refrigerant as the go-between and absorbs heat from the space that needs cooling. These vapour systems have 4 components known as: a compressor, a condenser, a throttle valve, and an evaporator. The saturated vapour is compressed to a higher pressure, thus resulting in higher temperature. The hot vapour finds its way through a condenser where it is turned into a liquid by flowing through tubes. This is where the refrigerant rejects the heat that comes from the system, and as a result, carries it away by water or air.
The condensed liquid refrigerant, which is also known as saturated liquid, is then routed through a valve that undergoes pressure reduction. This pressure reduction results in liquid evaporation. Generally, the higher the compression ratio, the higher its temperature will be. However, many compressor manufacturers have resolved this issue by creating a compressor that simultaneously cools the gas on a per-stage basis.
Different compressors have different horsepower capacities. Some can be up to a few thousand horsepower, while others require oil in order to work properly. There is a huge difference between commercial fridge mechanisms and residential ones. The compressor of a commercial refrigerator is much stronger and can withstand constant closing and opening of the door, whereas if you have a normal fridge, there will be some amount of heat lost every time you open and close its door. This is why stronger compressors are used for commercial refrigeration.
More than 70 per cent of the food that is served in a restaurant would have gone through commercial refrigeration at least once or twice. This is the importance of the compressor as it needs to be powerful enough to keep raw food fresh. Because of this very reason, it’s essential that you pick the right refrigerator for your catering establishment. Different foods require different refrigeration. If they are stored at an incorrect temperature, there will be a possibility of bacterial growth. This can be hazardous for your business, especially when health inspectors come for an inspection, or worse, when one of your customers gets food poisoning.

When it comes to choosing the best commercial refrigerators, you should pay special attention to their compressors. Make sure they are suitable for heavy duty use and have adequate horsepower. Most compressors can be found beneath the fridge, which makes them easier to clean and maintain. They are also highly resistant to damage, which can easily occur in busy commercial kitchens.
