How do Freezers work?
The way that a freezer works is very simple and most freezers operate in a similar fashion. They take warm air and make it cooler by transferring the heat using evaporation principles. All freezers have these components: a compressor, condenser, evaporator, capillary tube, and a thermostat. Freezers with an automatic defrost cycle have small heaters in strategic places to defrost ice buildup and a timer to control the defrost cycle. The compressor runs any time the thermostat sends electricity to it and turns it on. If the freezer has an automatic defrost cycle, the compressor will not run during it. The compressor compresses a refrigerant gas that is low-pressure, and by the act of compression, it makes it a hot, high-pressure gas. The hot gas flows through a set of condenser coils where it dissipates its heat, and condenses into a liquid. The condenser coil is a system of bent tubes that run through thin pieces of metal. These thin pieces of metal are sometimes referred to as fins. T
