Embodiment Construction

[0027] The high-tech energy building of Beijing University of Technology uses a ground source heat pump system. When measuring the change of underground temperature and the temperature diffusion radius, 6 sets of temperature measurement components are installed, as shown in Figure 5, in which the temperature measurement components 12 and 15 are respectively installed In the two energy wells 10, this can reduce the number of wells and save costs. Others are installed in special test wells. The distance between the two energy wells is 5 meters. The temperature measurement part 14 is installed in the middle of the two energy wells. Component 11 is installed at 2 meters directly above temperature measuring component 14 , temperature measuring component 13 is installed at 3 meters directly below temperature measuring component 14 , and temperature measuring component 16 is installed at 2 meters directly below energy well 10 .

[0028] The depth of the well is 60 meters. Each test we...

Abstract

The invention relates to an apparatus and method for measuring temperature changes and radius of temperature emission of geothermal pump energy well in the field of system technology of geothermal pump energy which comprises the following steps: making temperature sensor (5) into pipe (4), connecting one side of leader (9) with temperature collection part (2) on the ground, with the other side outside the pipe by the whole which is posited on the pipe (4) and contacted with soil (7), sealing the parts between temperature sensor and the whole on the pipe and pipe's opening parts on both extremities with potting material(6). Using the apparatus to measure energy well's initial temperature and systems stabilization temperature, using the pin between testing well which differential temperature over 15% of the initial temperature and has the furthest distance with the energy well and energy well as influence radius.

Description

technical field [0001] The invention relates to the technical field of ground source heat pump systems. Background technique [0002] The ground source heat pump uses the heat exchanger installed in the energy well to extract heat from the surrounding soil in winter to meet indoor heating needs, and discharge indoor heat into the surrounding soil in summer to complete indoor cooling. Referring to Fig. 6, it is a schematic diagram of a ground source heat pump system. Affected by the heat capacity of the soil and the heat transfer rate of the surrounding soil, the heat exchanger in each energy well can only obtain energy from a limited radius. If you cannot grasp the influence radius of temperature during the use of energy wells, in the design and construction process, either set the distance between energy wells too large, occupying more land, or set the distance between energy wells too small, and the heat transfer of the soil will deteriorate , affect the use effect. In ...
