Summary and discussion on design of high-efficiencyrefrigeration machine room in Wuhan Optics Valley Joy City

This paper presents the design of the high-efficiency refrigeration machine room in Wuhan Optics Valley Joy City shopping center from the aspects of load calculation, cold source equipment configuration, transmission and distribution system, control strategy, etc. The project adopts a primary pump variable flow system. The annual average design energy efficiency ratio of the refrigeration machine room is 5.2, and the operation energy efficiency ratio of the refrigeration machine room reaches 5.54. The path and means of further improving the energy efficiency ratio of the high-efficiency refrigeration machine room are summarized and discussed.
