冷凝热回收型地源热泵恒温恒湿空调系统的节能研究

摘要

For the climatic feature of the Yangtze River Delta rigion,designed a constant temperature and humidity air-condi-tioning system driven by ground source heat pump with condensing heat recovery.Established mathematical model of constant temperature and humidity air-conditioning respectively for summer and spring,and carried the theory calculate and analyse on constant temperature and humidity air-conditioning system driven by ground source heat pump with condensing heat recovery and that with conventional electric heating.The results show that the recovery condensing heat of constant temperature and humidity air-conditioning system driven by ground source heat pump with condensing heat recovery enough to heat the air had cooled and dehumidified to the required temperature range,which can reduce energy consumption by 40.2% in summer and 77.4% in spring compared to constant temperature and humidity air-conditioning system driven by ground source heat pump with conventional elec-tric heating.%针对长三角地区气候特点，设计了一种冷凝热回收型地源热泵恒温恒湿空调系统，分别就夏季和春季，建立恒温恒湿空气处理的数学模型，对冷凝热回收型地源热泵恒温恒湿空调系统和常规电加热型地源热泵恒温恒湿空调系统的耗能进行理论计算与分析。结果表明：冷凝热回收型地源热泵恒温恒湿空调系统回收的冷凝热足以把降温除湿后的冷空气加热到所需温度范围，与常规电加热型地源热泵恒温恒湿空调系统相比，此系统在夏季节能40．2％，在春季节能77．4％。
