【摘要】 结合应用场所的实际冷热负荷和热水需求情况，采用复合蒸发冷凝热泵机组、低温强热空气源热泵机组和热回收空气源热泵机组，进行“精准适配”的制冷、制热和制热水设计。以郑州某四星级酒店为例，介绍了这3种空调的原理、计算模型、节能率和运行费用。相比常规的空气源热泵机组和燃气锅炉的制冷、制热、制热水方式，该方案整体节能24.5%。并利用机组实际运行数据验证了该计算模型的准确性。更多还原

【Abstract】 Combined with the actual cooling and heating load and hot water demand of the application site, the compound evaporative condensation air-source heat pump units, low temperature strong hot air-source heat pump units and heat recover air-source heat pump units are adopted for the accurate adaptation design for refrigeration, heating and hot water. Taking a four-star hotel in Zhengzhou as an example, this paper presents the principle, calculation model, energy saving rate and operation cost of these three kinds of air conditioning units. Compared with conventional air-source heat pumps and gas boilers, the energy saving rate of this case can rise by 24.5%. The accuracy of the calculation model is verified by using the actual operation data of the units.更多还原
