Electronic expansion valve

An electronic expansion valve performs the injection in the evaporator and ensures. Using the electronic expansion valve offers yet another advantage. An electronic expansion valve is the best of both worlds. For variable capacity systems, an electronic expansion valve provides superior performance as compared to a thermostatic expansion valve. Electronic valves work in a similar way to thermostatic valves, except that the temperature is sensed electronically and this signal is used to open and close the valve. Electronic valves are more expensive than other types and are most likely to be financially attractive when installed as part of a new installation or in retrofit to a larger system.  The A/C expansion valve is split into two sides, a high pressure side and a low. Before you go and replace that A/C Expansion valve check the inlet port screen .The expansion valve allows the refrigerant to be sprayed on the evaporator. Most air conditioning systems have five mechanical components: A compressor; an expansion valve or metering device; an evaporator coil. Thermostatic Expansion Valves (TXVs) are an optional upgrade to your air conditioning system. In an expansion valve air conditioning system, refrigerant flow to the evaporator varies according to the pressure in the suction line.  There are three kinds of control valves for liquid:-Three types or liquid control devices are included: capillary tube, thermostatic expansion valve, and an automatic expansion valve. Vehicles are found to have primarily three different types of air conditioning systems. While each of the three types differs, the concept and design are very similar to one another.
