[Abstract]:The birth and development of air conditioning technology not only provides great convenience for people to create comfortable building environment, but also brings great increase in building energy consumption and deterioration of indoor air quality. Mixed cooling (Mixed-Mode Cooling) is to meet the thermal comfort of indoor personnel by adopting different cooling methods under different climate conditions in summer. A cooling method to reduce building energy consumption and air conditioning operation cost at the same time. In this paper, the mixed cooling of office buildings in Zhuzhou area with typical climate characteristics in hot summer and cold winter area is combined with theoretical calculation and numerical simulation. But the running strategy is studied, In order to provide a reference for the application of hybrid cooling technology in the field of building energy conservation, this paper first reviews the current research situation of mixed cooling at home and abroad, based on the analysis and summary of previous research results, The key to achieving the desired goal of mixed cooling is an effective operational strategy. In this paper, the mixed cooling operation strategy of office buildings in hot summer and cold winter area is studied from the following three aspects. As a low energy consumption cooling mode, this paper studies the mixed cooling operation strategy of office buildings in hot summer and cold winter area. The ventilation cooling mode will directly affect the building energy consumption. Firstly, starting with the basic theory of ventilation cooling, this paper introduces in detail the action principle of different ventilation modes, classical ventilation research models, methods and conclusions, and ventilation functions. The thermal comfort theory and the building thermal balance theory provide the theoretical basis for the subsequent theoretical analysis. Based on the standard of thermal comfort adaptability under non-heating and air-conditioning environment, the requirement of indoor air quality and the theory of building heat balance, The requirements of both thermal comfort and indoor air quality are determined as mixed cooling operation parameters. Taking the typical office buildings in Zhuzhou area as an example, the range of thermal comfort temperature is determined on the basis of analyzing the local typical meteorological data. The mixed cooling operation strategy is established. The effectiveness of the hybrid cooling operation strategy is theoretically analyzed by building model and related theoretical calculation. Finally, the thermal process of the building model is simulated by using de St software. The thermal comfort satisfaction rate and energy saving potential of the operation strategy are simulated and analyzed respectively. In order to verify the application effect of the hybrid cooling operation strategy proposed in this paper, the mixed cooling operation strategy of office buildings in hot summer and cold winter area is studied and analyzed by the combination of theoretical calculation and numerical simulation. It can provide reference for the application of hybrid cooling technology in the field of building energy conservation.
