空气源热泵在西安地区应用的实验和理论研究

Experimental and Theoretical Studies of Air Source Heat Pump Application in Xi'an

以西安建筑科技大学冶园宾馆为对象,研究空气源热泵在西安地区的应用。首先分析了西安地区的气候特点和空气源热泵系统对环境条件的要求,接着在该建筑夏季和冬季典型日空调稳定运行时,选择有代表性的大厅进行温度、速度以及相对湿度的实测,同时在此基础上进行CFD模拟,结果表明空气源热泵在该地区应用是可行的。针对机组的结霜情况,对冬季室外环境进行了为期一个月的温度和相对湿度监测,数据显示空气源热泵在西安地区冬季运行时是比较可靠的。

Taking the Yeyuan Hotel of Xi＇an University of Architecture and Technology as the example, the paper studies the air source heat pump application in Xi＇ an. It firstly analyzes the characteristics of the climate in Xi＇ an and the requirements of environmental conditions in using air source heat pump, then introduces temperature, speed and relative humidity measurements of a lobby when the air-conditioning running stably in this building in summer and winter, at last simulates airflow by using CFD technique. All these results verify that the air source heat pump can be used in this region. On the basis of frost condition of outdoor unit when air source heat pump nmning in winter, one-month winter outdoor temperature and relative humidity was monitored, and the data shows that air source heat pump can be used in Xi＇ an reliably.
