HEATER, DEFROST W/THERMOSTAT
SKU: NOR158571
Condition: NEW
The defrost mechanism in a refrigerator heats the cooling element (evaporator coil) for a short period of time and melts the frost that has formed on it. The resulting water drains through a duct at the back of the unit. Defrosting is controlled by an electric or electronic timer: For every 6, 8, 10, 12 or 24 hours of compressor operation it turns on a defrost heater for 15 minutes to half an hour.
A defrost thermostat opens the heater circuit when the evaporator temperature rises above a preset temperature, 40°F (5°C) or more, thereby preventing excessive heating of the freezer compartment. The defrost timer is such that either the compressor or the defrost heater is on, but not both at the same time.
A heating element converts electrical energy into heat through the process of Joule heating. Electric current through the element encounters resistance, resulting in heating of the element. This process is independent of the direction of current.
A thermostat is a device that is used to control the temperature in restaurant equipment such as ovens, grills, fryers, and refrigeration units. The thermostat is an integrated component and is connected to a temperature sensor, which measures the temperature inside the equipment. The thermostat uses this information to control the heating or cooling elements in the equipment, turning them on or off as needed to maintain the desired temperature. This allows the equipment to operate at the optimal temperature for the specific food or beverage being prepared, ensuring that it is cooked or cooled to the proper level.
