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 Refrigerated Cold Room.
Cold rooms are staples of restaurants, hotels, supermarkets, and any other place that needs to store fresh, frozen, or pre-cooled food products. Cold rooms, also called walk-ins, are enclosed, refrigerated storage spaces that have footprints generally smaller than 3000 square feet and can be used for things such as storing perishable food items or packaging food. Cold rooms are often used as medium-term cold storage—with standard refrigerators acting as short-term storage and refrigerated warehouses acting as long-term storage. Just like any refrigeration system, cold rooms use an evaporator inside the unit and a condenser outside the unit to move heat outside, thus cooling the inside.
Another way to increase efficiency is to install curtains at the doors. Whenever an employee enters or exits the cold room, heat from the outside comes into the cold room. This in turn requires the system to use more energy to bring the temperature back down. Curtains help reduce temperature fluctuations inside the cold room. There are typically two kinds of curtains: strip and air. Strip curtains are made up of thick plastic sheets cut into strips while an air curtain is made up of a wall of air, blasted at a high velocity from directly above the door. Both designs help keep the temperature of the cold room low and its efficiency high.
