Abstract: During the research on operating characteristics of mechanical vapor recompression heat pump evaporator system, taking water as the test medium, such system performance parameters as total moisture extraction rate and system pressure ratio are found to be changed with evaporating temperature. It can be known that the total moisture extraction rate increases with the evaporating temperature, and such increases are obvious; the system pressure ratio decreases as the evaporating temperature rises, but such decreases are not obvious; the volumetric efficiency, adiabatic internal efficiency, Coefficient of Performance and heat transfer coefficient increase with the evaporating temperature. Therefor, mechanical vapor recompression heat pump evaporator system could have a better development in future practical application.
