In the restaurant industry, storing large stocks of food and ingredients is a must to keep the firm running. The daily consumption in such places is easier accounted for when the food stocks are kept at a definite level. Domestic refrigerators are inadequate to cater to this need. For this purpose, walk-in refrigerators are used.
Walk-in refrigerators, in straightforward terms, are large rooms that are temperature controlled. These can range in size, beginning from 100 sq. Feet and going up to 350 sq. Feet or more, depending on the needs of the user.

Many of these state of the art machines integrate an Lcd screen, suggesting what type of food should be stored at what temperatures and the expiry dates of the food stored. As these refrigeration units use filters to purify the air circulating within the room, they come with a filter status indicator. Walk-in refrigerators include some cooling zones. Air from the freezer section is diverted to the refrigerator door, helping to keep milk or juice in the door shelf colder. A power failure warning is built in to alert the user, commonly by flashing the temperature display. The maximum temperature reached during the power failure may be displayed, along with information on whether the icy food has defrosted or may include harmful bacteria. These features are mandatory in a walk-in refridgerator as huge quantities of food stocks are stored.
Walk-in refrigerators are easy to profess since they are frost-free. Over time, atmospheric water vapor condenses onto the cooling coils and forms ice. In a refrigerator qualified for frost-free operation, a heater and a thermostat are fitted around the cooling coils. The cooling is periodically switched off and the heater is turned on until the temperature around the coils slightly exceeds the icy point of water. Once the ice around the cooling coil melts, normal cooling is resumed.
Walk-in freezers are very valued when storing large quantities of icy foods. In other settings, laboratories use freezers to keep samples from contamination or degradation. Refrigerators have not only made life straightforward at home, but also brought about some conveniences at the market level, as well.
