酒店热水用水规律与热泵热回收系统设计

Study on the Use Law of Domestic Hot Water in Hotel and Design of Heat Pump Heat Recovery System

介绍了空气源热泵热回收系统原理,分析了目前热回收系统研究存在的问题。通过对2家酒店实际热水用水情况调查,分析了酒店的逐时和逐日的用水规律。并基于实际调查的用水规律,应用EnergyPlus软件对酒店空调及热水的全年逐时动态负荷模拟,探讨了该酒店的热回收潜力,并对该酒店利用热回收系统进行设计分析。

The principle of the heat recovery air-source heat pump system was introduced, and the problems existing in the system were analyzed. Through the field investigation of domestic hot water use in two hotels, the hourly and daily use laws of domestic hot water were concluded, and then all-year hourly dynamic load were simulated by applying sofiware-EnergyPlus. Based on the simulation result, the potential of condenser heat recovery was discussed, and the design of heat recovery system in the hotel was analyzed.
