文摘The use of R22 is rec0mmended in this paper because it offers a low ozone depletionpotential and it has been identified as an appropriate interim alternative refrigerant forchina’s shipping industry. This paper is just engaged in the research of the thermodynamicalperformance of Liquid-injection cooling Valve. The experimantal results show the feasibilityof the application of Liquid injection Valve. The special designed liquid-injection coolingva1ve is successfully used to control the exhaust temperature of the compressor when R22substitutes for R22.
