Remote refrigeration involves cold storage units you might see in commercial properties. When learning about remote refrigeration, it's helpful to learn about other types of refrigerators and how they differ. A remote fridge has a different setup than what we're used to from our refrigeration system at home.
My primary goal is to provide information and resources on everyday items used in the kitchen. I researched the best products on the market. Now, I can give an informed opinion on what you need to transform your kitchen into an amazing and functional space. That involves revealing the differences between certain appliances which can get confusing.
Stay tuned as we break down the following:
A remote refrigeration system consists of a cold storage unit with evaporators built into the structure. The shell that houses the products is fully insulated, but the compressor and the condenser are found in a separate unit. It takes an extensive framework system to transport the coolant solution between these two units.
By and large, the commercial coolers that we see in stores have self-contained refrigerator systems. This unit has the evaporator coil and condensing unit constructed inside the cabinet. That may mean the condenser is anywhere on the unit-bottom, sides, top, or even the back of the cooler. The evaporator will always be on top.
When storing food, you must keep the unit at the correct temperature to ensure freshness. Some tubes connect all the necessary parts of the refrigeration system with the coolant that keeps the food from going bad.
Manufacturing companies prefer self-contained refrigeration. Self-contained refrigerators offer reliability and don’t require as many warranty calls related to performance failure. With remote refrigeration units, the company has to install the cooling system properly. This ensures that it has a low temperature suitable for storing food. If not, the commercial freezer or fridge will fail.
Most of the commercial freezers and refrigerators you see in the U.S. are self-contained refrigeration equipment. There are certain instances where remote refrigerators are better. An example would be the kitchen having limited ventilation.
Also, if the facility has low ceilings, the remote fridge would be better. The self-contained refrigerator might not have the capacity to draw enough air to operate. This makes it less efficient even though it's working harder.
Grocery stores almost always choose remote refrigeration. They have large sections of blast chillers, walk-up coolers without a door, and other cold storage units. You may notice on a trip to your local supermarket that these commercial refrigerator units are quiet because they have a remote condensing unit to keep their contents at a low temp.
How remote refrigeration works in a grocery store
Companies opt to separate these machines from the evaporator and condenser. They aim to prevent the excessive noise and heat that these machines generate around customers. In a grocery store, this separate system might be up on the roof or in a separate room.
Some people believe that several units can operate through one compressor/condenser unit, which isn't true. It is possible that multiple remote refrigeration units can get connected to one rack system that appears as a single cooling tower. However, inside there has to be a single condenser for each cooler.
