Summary

Presents the method of adjusting heat recovery proportion through controlling the number and the rotating speed of the fans in operation and the analysis method of heat recovery integrated COP. Studies and analyses the variance characteristics of operating parameters and system performance of refrigerating systems. The results show that the refrigerating COP increases 14% to 22% and 3.9% to 6.2% respectively and the heat recovery integrated COP reaches 4.44 to 6.67 and 3.9 to 5.51 respectively for leaving heating water of 45? and 50? and that the power consumption increases 3.6, 6.7 and 14.7 kW respectively for 292, 257 and 186 kW recovered heat at 45,50 and 55? leaving heating water temperature.
