2. Auto-defrost - Wikipedia

   en.wikipedia.org/wiki/Auto-defrost

   "Frost-Free" refrigerator/freezer units usually use a heating element to defrost their evaporators, a pan to collect and evaporate water from the frost that melts from the cold plate and/or evaporator coil, a timer which turns off the compressor and turns on the defrost element usually from once to 4 times a day for periods usually ranging from ...

3. Thermal expansion valve - Wikipedia

   en.wikipedia.org/wiki/Thermal_expansion_valve

   A thermal expansion valve is a key element to a heat pump; this is the cycle that makes air conditioning, or air cooling, possible.A basic refrigeration cycle consists of four major elements: a compressor, a condenser, a metering device and an evaporator.

4. Heater core - Wikipedia

   en.wikipedia.org/wiki/Heater_core

   In a car equipped with air conditioning, outside air, or cabin air if the recirculation flap has been set to close the external air passages, is first forced, often after being filtered by a cabin air filter, through the air conditioner's evaporator coil. This can be thought of as a heater core filled with very cold liquid that is undergoing a ...

5. Evaporator - Wikipedia

   en.wikipedia.org/wiki/Evaporator

   An evaporator is a type of heat exchanger device that facilitates evaporation by utilizing conductive and convective heat transfer, which provides the necessary thermal energy for phase transition from liquid to vapour. Within evaporators, a circulating liquid is exposed to an atmospheric or reduced pressure environment causing it to boil at a ...

6. Heating, ventilation, and air conditioning - Wikipedia

   en.wikipedia.org/wiki/Heating,_ventilation,_and...

   Dehumidification (air drying) in an air conditioning system is provided by the evaporator. Since the evaporator operates at a temperature below the dew point, moisture in the air condenses on the evaporator coil tubes. This moisture is collected at the bottom of the evaporator in a pan and removed by piping to a central drain or onto the ground ...

7. Circulation evaporator - Wikipedia

   en.wikipedia.org/wiki/Circulation_evaporator

   Removing of the circulation pump reduces the operating costs, however due to characteristics of the system as mentioned above the evaporator has a long residence time and low flow rates, [11] making its uses severely more limited than a forced circulation evaporator. The most common application of Natural Circulation evaporation is as a ...
