| Abstract: | The exhaust air heat recovery fresh air unit, which consists of total heat exchanger and heat pump unit, was put forward, and the fresh air unit, was applied in fan coin air conditioning system for realizing temperature and humidity independent control. An office building in Nanjing is selected, and the annual hourly air conditioning load is calculated by DeST software. The mathematic model for simulating performance of the system is set up. The simulation analysis of cooling performance of the system in typical year is carried out. The simulation results showed that the system can independent control temperature and humidity well, and the coefficient of performance (COP) of the system is 4.58. The energy saving rate of the system is 42.8% compared with conventional air conditioning system. |
