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

온도식팽창밸브의 전자식팽창밸브로의 대체 가능성에 관한 연구

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.
