Application and energy-saving analysis of water-loop heat pump air conditioning system in a super high-rise building

This paper presents the design and application of a water-loop heat pump air conditioning system in a super high-rise building. The system is composed of cooling tower, air-source heat pump, water-cooled precision air conditioning unit, and water-source variable refrigerant volume system host through pipe networks. Based on the cold and heat distribution, heat balance, and outdoor air system settings of the entire water-loop heat pump air conditioning system, the heat recovery amounts of the system and the outdoor air system are analysed, and the corresponding operation strategies are given.
