ABCs of Refrigeration Pressure Sensing
liquid refrigerant passes through an expansion valve where it undergoes a rapid reduction in pressure. The refrigerant boils as it converts back to a vapor. The phase change from liquid to vapor produces a large drop in vapor temperature. The cold vapor passes through the evaporator where it absorbs
