How do thermal expansion valves work
WebHow a Thermostatic Expansion Valve Works in Heat Pumps Simply, a TEV has the main purpose of controlling how much refrigerant passes through the heat pump system’s evaporator before reaching the compressor. Most, especially older type heat pumps and AC systems use a piston or orifice as a metering device, instead of a TXV. WebA 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 …
