Car AC Expansion Valve?
The expansion valve is placed at the evaporator inlet tube. The expansion valve is used to control refrigerant flow into the evaporator. Excessive refrigerant circulation into the evaporator can cause evaporator surging, which can result in decreased ac efficiency and possible air compressor damage.Too little refrigerant circulation can cause evaporator frosting or decreased ac efficiency. The Expansion valve device contains a diverse hole that is handled by a feeling light placed in the evaporator air conditioning bout. The feeling light is a made pipe containing a bit of refrigerant. The changes in temperature of the evaporator cause the refrigerant in the feeling light to grow or contract. The action of the internal stress of the feeling light handles the quantity of refrigerant that moves through the Expansion valve device by different the size of the hole. Expansion valves are used more often in ac techniques equipped in brought in and older domestic vehicles. The techniqu
