Aim at the buildings with no heating network around and high environmental protection requirements in cold areas, the air source double stage coupled heat pump conditioning system with an energy storage tank driven by the lower price electricity was put forward.The system composition and operation principle were introduced,and then the optimization target variable was de-termined by analyzing,the mathematical model was set up for system optimization design.Taking the 126m2 office building as the research object,the impact on the economy about capacity and shutdown temperature of the heat pump was studied.The results show that under the climate condition of Urumqi,the optimal shutdown temperature of coupled heat pump is 20℃,rated heating capacity is 8kW,the annual system average coefficient of performance (COP)is 1.71,and the annual operating cost is 4% higher than the centralized heating and split air conditioning scheme.The above results indicate that the system has certain feasibility.
