摘要
冷水相变机与空气源热泵耦合系统具有良好的制热效果和节能效益,为研究不同工况对该耦合系统能耗特性的影响,以青岛某建筑为研究对象,对冷水相变机与空气源热泵耦合系统进行了仿真,分析室外温度和负荷侧供水温度共同调控时该耦合系统的运行能耗与系统能效比(COP),比较典型日下系统的制热性能。结果表明:当室外温度控制值为1℃,负荷侧供水最低温度控制值为35.5℃时,采用耦合控制系统,供暖季总能耗与最冷日运行能耗均为最低,相较于传统空气源热泵系统能耗分别降低了9.5%和9.86%,系统COP分别提高了22.53%和54.2%。
The coupled system of cold water phase change machine and air source heat pump has advantages on heating and energy saving.To study the effect of different working conditions on energy consumption characteristics of the coupled system,taking a building of Qingdao as the research object and using simulation,the operation energy consumption and COP of the coupling system under the co-regulation of outdoor temperature and load side water supply temperature are analyzed.The heating performance of typical days is compared.The results show that when the control value of the outdoor temperature is 1℃,that of the minimum water supply temperature on the load side is 35.5℃,and the coupled control system is adopted,the total energy consumption in heating season and operating energy consumption in the coldest day are the lowest.Compared with the traditional air source heat pump system,the energy consumptions are reduced by 9.5%and 9.86%respectively,and the COPs of the system are increased by 22.53%and 54.2%respectively.
