The design of a refrigerating system used for experiments and parts of experimental results on it were introduced. In the system, the method of simulating heat load with the heat of cooling water was applied to simplify the system and to save the cost. And the modern technologies such as regulating the cooling amount by frequency converter, adjusting system parameters by PID governor, and etc, were used to improve operating and controlling performances. So it provided good conditions for teaching research. The designing techniques of it and experimental results on it could provide convenience for the development of refrigerating and air control products, the technical improvement of old products, and the design of similar experimental devices.
