| description | Combining with a ground source heat pump project in Nanjing, the key issues of Geo-thermal response test are analyzed and the normative test methods and steps are summarized. Vertical double U-tube test wells are taken as testing apparatus, and local soil thermal parameters are collected through field test of two test wells with depth of 100m. Furthermore, the original ground temperature and the inlet and outlet water temperature response curve of the underground heat exchanger are also obtained, which are used to determine the heat exchange quantity of per well depth and other parameters. It is concluded from data analysis: the original ground temperature is 17.95℃; the heat exchange quantity of per well depth is 69.6W/m under summer conditions (35℃) and 51.2W/m under winter conditions (5℃). All of those conclusions prove that comprehensive geological conditions of the project area are suitable for the use of ground source heat pump air conditioning system. |
