【摘要】 针对夏热冬冷地区酒店类建筑,采用空气源热泵热水器制热水方案,设计中结合用电峰谷电价差,遵循设备利用率最大化原则。提出酒店不同季节、不同住宿率部分热水负荷状况下的动态运行控制策略,并对热泵机组装机容量和蓄热水箱的容积设计进行探讨。分析了蓄热水时热泵机组COP对能效的影响。结果表明,控制策略使热泵机组装机容量得到降低,在酒店部分住宿率、部分热水负荷需求情况时可以解决传统的整套热泵机组运行能源浪费问题,消除酒店热水供应系统"大马拉小车"现象。更多还原

【Abstract】 The hot water production scheme using air source heat pump water heater system is used in hotel buildings in hot summer and cold winter areas.Combined with peak and valley electricity price difference,the principle of maximum equipment availability is observed.Dynamic operation control strategy under partial hot water loads for different occupancy rates in different seasons for hotel buildings was presented.The installed capacity of heat pump water heater and the volume of hot water storage tank were discussed.The influence of heat pump COP on energy efficiency during storage of hot water was analyzed.The results demonstrated that the installed capacity of heat pump water heater was decreased.Under partial occupancy rates and partial hot water loads,the problem of energy waste for the typically whole heat pump water heater system could be solved.The phenomenon of "a powerful horse pulling a small cart" of the hotel hot water supply system could be eliminated.更多还原
