Abstract：
With a project in Shanghai, presents the indoor and outdoor air design conditions, load calculation, equipment selection and operation strategy of the system which consists of air-source heat pump, air-source heat pump heat recovery unit, cooling tower and water-loop heat pump. Economic analysis shows that this system has lower operation cost than that of traditional air-source heat pump system and water cooling VRF combined with gas boiler system.
