How do thermal expansion valves work

WebThe expansion valve is a passive orifice through which the liquid refrigerant is forced by the pressure difference between the condensing and the evaporating conditions. If a system could always operate at fixed conditions, correctly charged, a simple restriction would fulfil the requirement. WebThe water-cooled chiller operates by circulating water or other fluids through the evaporator. The evaporator cools the fluid by transferring heat to the refrigerant. The refrigerant then flows to the compressor, where it is compressed and heated. The hot, high-pressure gas flows to the condenser, where it releases heat into the environment.
