摘　　要：基于TRNSYS软件建立空气源热泵供暖系统仿真模型,模拟空气源热泵供暖运行性能,对比分析不同供水流量、不同月份以及3个典型供暖日下的系统COP。研究结果表明:室内温度及系统COP随室外温度的升高而升高,系统耗电量随室外温度的升高而降低;当室外温度恒定时,室内温度和系统耗电量随供水流量的增大而增大,但系统COP随供水流量的增大而降低;供暖期开始和结束时,空气源热泵运行性能稳定、满足供暖热舒适需求,供暖期室外温度最低时不宜单独使用空气源热泵。研究结果可为空气源热泵供暖系统在包头地区的应用提供指导。The heating system simulation model of air source heat pump is established based on TRNSYS software.The heating operation performance of air source heat pump is simulated.The COP of the system under different flow rates of water supply,different months and three typical heating days is compared and analyzed.The study results show that the indoor temperature and COP of the system increase with the increase of outdoor temperature,and the system electricity consumption decreases with the increase of outdoor temperature.When the outdoor temperature is stable,the indoor temperature and the electricity consumption of the system increase with the increase of the flow rate of water supply,but the COP decreases with the increase of the flow rate of water supply.At the beginning and the end of the heating period,the operation performance of air source heat pump is stable,and it can meet the needs of heating comfort.Air source heat pumps should not be used alone during the coldest heating period.The study results can provide guidance for the application of air source heat pump heating system in Baotou area.
