Soil source geothermal energy heat pump energy-saving heat supplementing and cold supplementing device

Abstract

The invention relates to the technical field of geothermal utilization, and discloses a soil source geothermal energy heat pump energy-saving heat supplementing and cold supplementing device which comprises a base. A geothermal energy heat pump unit and a temperature supplementing box are fixedly connected to the upper end of the base, and a partition plate is fixedly arranged in the temperature supplementing box and divides the temperature supplementing box into a refrigerating cavity and a heating cavity; the output end of the geothermal energy heat pump unit is fixedly connected with a heatexchange pipe, the end, away from the geothermal energy heat pump unit, of the heat exchange pipe penetrates through the upper end of the base and extends into the ground surface, and the end, located in the ground surface, of the heat exchange pipe penetrates through the lower end of the base and penetrates through the temperature supplementing box to extend to the position above the temperaturesupplementing box; and the upper end and the lower end of the outer side wall of the temperature supplementing box are fixedly sleeved with temperature control boxes. According to the soil source geothermal energy heat pump energy-saving heat supplementing and cold supplementing device, before heat exchange with an indoor space, fluid can be subjected to heat supplementing or cold supplementing,the temperature stability of the fluid is guaranteed, the heat exchange effect with the indoor space is improved, meanwhile, heat of backflow fluid can be recycled and stored, heat energy waste is reduced, and the energy-saving effect is good.

Description

technical field [0001] The invention relates to the technical field of geothermal utilization, in particular to an energy-saving heat and cooling device for a soil source geothermal heat pump. Background technique [0002] Ground source heat pump is a device that transfers low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy (such as electric energy) from shallow land energy. Usually, ground source heat pump consumes 1kWh of energy, and users can get more than 4.4kWh of heat or Cooling capacity. [0003] At present, the temperature of the soil source is generally 12°C-22°C in winter, and 18°C-32°C in summer. In winter, the temperature of the soil source is higher than the indoor temperature to heat the room. The indoor temperature is lower than the indoor temperature, but in the actual use process, because the temperature of the soil source is not stable, the effect of heating or cooling the room is different, which affects the us...
