不同建筑面积下冷热双蓄空调系统的运行费用

Operating Cost of Thermal Storage Air-Conditioning System under Different Construction Areas

本文以江苏省南京市建筑面积为2×10^(4)m^(2)和1×10^(5)m^(2)的写字楼办公建筑为研究对象,研究地源热泵+冷水机组+水冷热双蓄和冷水机组冰蓄冷+电锅炉水蓄热两种技术路线配置方案的运行成本。结果表明,蓄能空调系统的运行成本与主机容量、效率和水泵等其他辅助设备容量密切相关;地源热泵+冷水机组+水冷热双蓄配置方案的运行成本低于相同情况下电锅炉水蓄热+冷水机组冰蓄冷。

Taking the office buildings with a construction areas of 2×10^(4)m^(2)and 1×10^(5)m^(2)in Nanjing,Jiangsu Province as the research object,this paper studies the operating cost of the two technical route configuration schemes of ground-source heat pump+water chiller+water cool and heat storage and water chiller ice cool storage+electric boiler water heat storage.The results show that the operating cost of the thermal storage air-conditioning system is bound up with the capacity and efficiency of air conditioning host,the water pump and other auxiliary equipment capacity of the main engine etc.The operating cost of the technical route configuration scheme of ground-source heat pump+water chiller+water cool is lower than that of electric boiler water heat storage+water chiller ice cool storage under the same circumstances.
