The compressor takes in a low temperature, low pressure refrigerant vapor, and compresses it into a high temperature, high pressure vapor. This lowers the temperature of the refrigerant stream. WebAn evaporator or direct expansion (DX) coil works on the “refrigeration effect”. Cooling occurs when a fluid under pressure and at a temperature above its normal boiling point, has the pressure reduced. This makes the fluid want to boil or “flash” to a gas. For it to boil (“flash”), the liquid must absorb heat from its surrounding ... chrysalis design and landscaping
