Ground source heat pump unit capable of continuously and stably supplying heat

Abstract

The invention discloses a ground source heat pump unit capable of continuously and stably supplying heat. The ground source heat pump unit comprises a heat collecting cabin and a heat pump unit body,wherein the heat collecting cabin is arranged below the ground surface, and the heat pump unit body is arranged on the ground surface; a heat exchange plate is fixedly arranged in the heat collectingcabin, and the heat pump unit body is connected with the heat exchange plate through a circulating inlet pipe and a circulating outlet pipe for circulating heat exchange; a rotating shaft is vertically arranged at the center in the heat collecting cabin, and the two ends of the rotating shaft are connected to the inner wall of the heat collecting cabin in a rotating mode, and three heat storage mechanisms are arranged on the inner bottom wall of the heat collecting cabin in the circumferential direction of the heat collecting cabin at equal intervals; and a heat conduction plate used for transferring heat between the heat storage mechanisms and the heat exchange plate is fixedly connected to the side wall of the rotating shaft, and a control mechanism used for driving the rotating shaft torotate is arranged on the rotating shaft. According to the ground source heat pump unit capable of continuously and stably supplying the heat, heat energy is provided by the plurality of heat storagemechanisms in turn, so that circulating and stable heat supply in a limited area is ensured, and self-control actions are realized.

Description

technical field [0001] The invention relates to the technical field of geothermal energy, in particular to a ground source heat pump unit for sustainable and stable heat supply. Background technique [0002] At present, under the condition of tight energy supply and increasingly serious greenhouse effect, it is imminent to develop renewable energy utilization technology. Especially in the field of building energy use, the utilization of new energy has received widespread attention, such as the utilization of solar energy, wind energy, and geothermal energy. Among them, the utilization of wind energy and solar energy is relatively mature, while the utilization of geothermal energy is not mature enough. [0003] The existing ground source heat pump units have certain disadvantages in use. The existing heat pump units directly bury the buried pipes in the ground to absorb and transfer the heat energy in the soil to the heat pump machine. However, the heat energy stored in the s...

Problems solved by technology

[0003] The existing ground source heat pump units have certain disadvantages in use. The existing heat pump units directly bury the buried pipes in the ground to absorb and transfer the heat energy in the soil to the heat pump machine. However, the heat energy stored in the soil in an area is limited. After the heat energy is transferred, the soil needs to store energy again for a period of time, and because the heat energy that can be absorbed and stored per unit time is limited, the energy storage time is longer, and the heat energy supplied per unit time is more during heating, and faults are prone to occur in heating supply , in a limited soil area, the thermal energy transfer is insufficient, which affects the energy efficiency and heating stability of the entire heat pump unit
