Abstract
In response to the national strategy of energy conservation and emission reduction,the construction of ultra-low energy consumption multi-storey residential buildings.This paper calculates and analyzes the energy consumption of HVAC system in different seasons,analyzes the energy consumption composition of building structure,and puts forward the energy consumption optimization design scheme of air condition-ing system.The results show that the total cooling load of air conditioners in summer is 224.6 kW,and the total cooling load of air conditioners in winter is reduced by 12.3%compared with that in summer.In the structure of building energy consumption,the annual cooling consumption accounted for 68%;The minimum annual heat consumption is only 1%;The optimal design scheme of the air conditioning system includes double direct expansion high efficiency heat recovery type fresh air unit+refrigerant flow frequency conversion multi-coupled air conditioning unit,air supply and exhaust pipe and heat recovery type fresh air unit joint,photovoltaic array set on the roof,using the above scheme has ob-tained effective building structure energy-saving effect.关键词
