تعريف thermostatic expansion valve في الإنجليزية الإنجليزية القاموس.
A component regulating rate of refrigerant flow into evaporator as governed by evaporator outlet pipe temperatures sensed by the sensing bulb
A valve used in refrigeration systems to control the superheat in an evaporator by metering the correct refrigerant flow to the evaporator
A refrigerant metering valve that controls the flow of liquid refrigerant entering the evaporator in response to the superheat of the gas leaving it Its basic function is to keep the evaporator active without permitting liquid to be returned through the suction line to the compressor TXV's compensate for common installation problems caused by incorrect refrigerant charge and incorrect airflow
