英文摘要：

The concept of climate compensation in the heating system is introduced into the variable air volume air-conditioning system. The heat load value is expressed as a function of supply air temperature by heat exchange analysis. The scheme of climate compensation and the method of optimizing supply air temperature set-point are proposed by analyzing the heat exchange and the control parts in the air-conditioning system. The set-points of air supply temperature under multiple conditions in winter are optimized based on the proposed compensation scheme on the experimental platform. Smith predictive control strategy is adopted to control the air supply temperature. The system in the optimal air supply temperature operation can have up to 35.5 % energy saving than that in other working points through experiments. This method is proved feasible and has a certain energy saving, which can be used as a reference scheme for engineering application.
