Abstract

With the increasingly prominent global energy and environmental problems, efficient HVAC (Heating, Ventilation, and Air Conditioning) system driven by renewable energy has become a research hotspot. The purpose of this article is to explore the design and performance assessment methods of this kind of system and provide theoretical and practical support for its popularization and application. Through theoretical analysis and case study, the application principle and types of renewable energy in HVAC system are expounded first, and then the key points of efficient system design are discussed, including system architecture, selection of key components and adaptation to building environment. The performance assessment adopts the method of combining experimental test and simulation, and selects the HVAC system driven by ground source heat pump in a 10000 square meter green office building in Shanghai as a case. The results show that the heating COP of the system is 3.8, the cooling EER is 4.2, the annual carbon emission is 150 tons, the investment payback period is 5 years, and the life cycle cost is 8 million yuan. This shows that the design method adopted is reasonable and the performance assessment index and method are effective, which verifies the potential and advantages of renewable energy in HVAC field.
