Abstract：
Introduces computer simulation technology into the refrigeration system design. Puts forward a novel air refrigeration flow scheme with high pressure dehumidification, surplus heat regeneration and positive pressurizing construction, decreasing the first costs of the system by about 30% and the total energy consumption and operation costs by over 50% by making full use of the surplus power, surplus heat and free cooling. The operation data show that all performance indexes of the system can satisfy the design demands.
