A walk-in chiller is a large, refrigerated room used for storing perishable goods at a consistent, cool temperature. Commonly found in restaurants, supermarkets, and food processing facilities, walk-in chillers are essential for preserving the freshness and quality of food items, preventing spoilage, and extending shelf life.The design of a walk-in chiller includes insulated walls, floors, and ceilings to maintain the desired internal temperature. The refrigeration system typically consists of an evaporator, condenser, and compressor, working together to remove heat from the interior and keep the space cool. The temperature inside a walk-in chiller is usually set between 32°F and 41°F
