Cheap thermostat heat pump, Buy Quality air conditioner thermostat directly from China valve thermostatic Suppliers: RTB-1 4.2kw(R410a) bi-flow thermostatic expansion valve with SAE flare connection for heat pump air conditioner
The thermostatic expansion valve (TXV) is a precision device, which is designed to regulate the rate at which liquid refrigerant flows into the evaporator. This controlled flow is necessary to maximize the efficiency of the evaporator while preventing excess liquid refrigerant from returning to the compressor.One of the design features of the TXV is to separate the high pressure and low pressure sides of an air conditioning system. Liquid refrigerant enters the valve under high pressure via the system’s liquid line, but its pressure is reduced when the TXV limits the amount of this liquid refrigerant entering the evaporator.
