由于控制逻辑简单,近年来风冷-地源热泵复合系统越来越多地受到关注。为分析风冷-地源热泵复合系统的经济性,本文以上海地区某小型空调系统为例,在系统全寿命期内采用费用现值和费用年值的方法,比较风冷-地源热泵复合系统、地源热泵系统、冷却塔复合式地源热泵系统、空气源热泵系统这4种类型系统经济性的差异。计算得到,4种空调系统的费用现值分别为64.14万元,67.96万元、65.77万元和64.79万元;4种空调系统的费用年值分别为8.43万元、8.94万元、8.64万元和8.52万元。结果表明,在这4种空调系统中,风冷-地源热泵复合系统的动态经济特性最优,具有较高的应用及推广价值。
Due to the simple control logic, more and more attention has been paid to the air-to-ground heat pump composite system in recent years. In order to analyze the economy of the air-to-ground heat pump complex system, this paper takes a small air-conditioning system in Shanghai as an example to compare the present value of the cost with the annual cost in the whole life cycle of the system. System, ground source heat pump system, cooling tower composite ground source heat pump system, air source heat pump system, these four types of system economic differences. Calculated, the present value of the cost of the four air-conditioning systems were 641,400 yuan, 679,600 yuan, 657,700 yuan and 647,900 yuan; the annual cost of the four air-conditioning systems were 84,300 yuan, 89,400 yuan, 86,400 yuan And 85,200 yuan. The results show that in the four air-conditioning systems, the dynamic and economic characteristics of the air-to-ground heat pump composite system is the best, which has high application and promotion value.
