Research on Control Stability of Cascade Air-source Heat Pump

Research on Control Stability of Cascade Air-source Heat Pump

For the cascade air-source heat pump operated under different environment temperature, the proper control of intermediate pressure is important. In this paper the principle that two stage compression ratio is approximately equal is used to determine the intermediate pressure at the optimal middle te...
