热回收型空气源热泵在酒店建筑中的应用
Application of heat recovery air-source heat pumps to hotel buildings
摘要：
以四川宜宾市某酒店建筑为例，简述了空调冷热负荷、生活热水负荷及其全年运行概况。基于当地的电价及燃气价格，对比了传统的燃气锅炉+水冷冷水机组能源形式与热回收型空气源热泵能源形式的初投资与运行费用，分析了电价与燃气价格对静态投资回收期的影响。提出了将电价、燃气价格、锅炉效率综合考虑的锅炉COP的计算方法，便于运行费用的计算及方案比选。结果表明，在酒店建筑中，热回收型空气源热泵作为空调冷热水与生活热水的热源有很好的经济性。
Abstract：
Taking a hotel building in Yibin city of Sichuan Province as an example, briefly describes the cooling and heating loads of air conditioning system, the heating load of domestic hot water and its annual operation. Based on the local electricity and gas price, compares the initial investment and operation cost of air-source heat pump heat recovery units with those of the traditional system of gas boilers and water-cooled chillers. Analyses the influence of the price of electricity and gas on the static investment payback period. Puts forward a calculation method of the boiler COP considering the electricity price, gas price and boiler efficiency, which is convenient for the calculation of operation cost and comparison and selection of schemes. The results show that in the hotel building, the air-source heat pump heat recovery unit has good economy as the heat source of air conditioning and domestic hot water systems.
