A Study on the Possibility for the Replacement of a Thermal Expansion Valve to an Electronic Expansion Valve

For the precise superheat temperature control of an air conditioner, an electronic expansion valve may be used instead of a thermal expansion valve. In this paper, technical and economical aspects of expansion valves were studied in order to find out the possibility to use an electronic expansion valve to replace a thermal expansion valve.
