A thermal expansion valve is a component in refrigeration and air conditioning
systems that controls the amount of refrigerant flow into the evaporator thereby
controlling the superheat at the outle...
This allows a specific amount of refrigerant, based on demand, to be metered into
the evaporator coil. The fixed orifice metering device allows the same amount ...
The liquid refrigerant is then routed to the metering device. This device restricts
the flow by forcing the refrigerant to go through a small hole which causes a ...
