摘要
针对竖直地埋管地源热泵系统运行特点,开发了地下换热井的测温系统。测量了地源热泵系统运行前换热井内的初始温度,推导出了适合长春地区的初始地温拟合方程。测量了地源热泵系统冬季供暖运行工况下地下换热井内的温度变化数据,总结出该地区冬季供暖时换热井内温度的变化规律。
In view of the operational characteristics of ground-source heat pump systems with vertical ground heat exchangers, develops an underground temperature measuring system. Measures the initial temperature in underground heat exchange wells before heat pump system operating, and obtains a fitted equation of initial underground temperature for Changchun area. Measures the temperature in wells during heat pump system operating in winter heating mode, and summarizes the change patterns of the temperature in wells in heating mode in this area.
