Walk in Cooler Refrigeration Unit

Walk in Cooler Refrigeration Unit


Walk in cooler refrigeration unit is an essential component for cold room. The walk in cooler refrigeration unit can keep the cold room temperature between -15 degree to 10 degree. Cold room is the basic facility of restaurants, hotels, supermarkets, and any other place that needs to store fresh, frozen, or pre-cooled food products. These walk-in cold room has enclosed, refrigerated storage spaces generally smaller than 3000 square feet and can be used for things such as storing perishable food items or packaging food.









Walk-in coolers are often used as medium-term cold storage facility which are equipped with standard walk in cooler refrigeration units acting as short-term storage and refrigerated warehouses acting as long-term storage. Just like any refrigeration system, walk-in coolers use an evaporator inside the unit and a condenser outside the unit to move heat outside, thus cooling the inside.

Refrigeration is important for maintaining a proper, unbroken cold chain. Using dairy as an example, after the cows are milked, their milk is pasteurized and rapidly chilled. Once the milk has been chilled, it must be maintained at that low temperature from the farm to the grocery store, including during bottling and shipping. If the cold chain is broken, bacteria or fungus can grow, making the food unsafe for human consumption. The United States Department of Agriculture requires that business-owned refrigeration systems have an internal temperature of 40°F or below for refrigerated food and 0°F for frozen food. Businesses operating refrigerators or freezers above these temperatures face fines and other penalties, so maintaining a reliable temperature is imperative. One of the most popular types of business-owned refrigeration systems is the walk in cooler.


Indoor and Outdoor Walk in Cooler Refrigeration Unit

When it comes to walk in coolers, it’s very important to choose a refrigeration system that works best for your cold room. Since we offer models with different BTUs and KMs, as well as units designed for indoor or outdoor use, you’ll be sure to find the unit you need for the size and location of your walk in cooler.

Walk in cooler refrigeration unit have two main parts, indoor unit and out door unit. Indoor unit also called air cooler or evaporator, out door unit also called condensing unit.

When it comes to walk in cooler refrigeration unit , which part is be most concern? Compressor, yes. Our company mainly us Germany Bitzer compressor and American Copeland compressor. Different compressor have its own advantage. Except compressor, which part also very important? Yes, the coil of indoor unit and outdoor unit. Coil, also called evaporator, it was composed by copper pipe and aluminum fin.


Refrigeration Cycle System

The refrigeration cycle for walk in cooler refrigeration unit is exactly the same as residential air conditioning system. However, the operation of the physical component is slightly different. Walk in cooler refrigeration unit system is controlled by a close on rise in temperature thermostat. You will find either a mechanical type with a sensing bulb or a digital thermostat with a thermistor. Most of the walk in coolers that require repair will be older and may have been retrofitted with a digital thermostat. The thermostat of the walk-in cooler determines the air temperature within it. When the temperature rises above the level of the thermostat, the condenser unit turns on to start a new cooling cycle. The unit’s fans pull air into the unit and then over the condenser’s coils.



The coolant within the coils pulls the heat from the air as it passes over. The cooled air then continues to move out the back of the unit, cooler than it was when it first entered. As the fans continue to blow air over the condenser, the air temperature within the walk in cooler will lower until it is once again below the level set by the thermostat. The coolant within the condenser coils will be continually pumped during the cooling cycle. This ensures that the coolant does not heat up too much before being given a chance to cool down again.



Why choose us?

OnlyKem can supply the whole set of walk in cooler refrigeration unit, include indoor unit, outdoor unit and control panel etc. Our refrigeration unit have following feature:
Temperature allow customized.
