Abstract
The invention provides a shallow layer geotherm utilization equipment and utilization method for improving energy efficiency of a ground source heat pump. The equipment comprises a first heat exchange assembly and a second heat exchange assembly. The first heat exchange assembly comprises a gas pipe and a gas pump. A gas inlet of the gas pipe is arranged outdoors. A gas outlet of the gas pipe is arranged indoors. The gas pump is arranged on the gas pipe. The second heat exchange assembly comprises an indoor heat exchanger arranged indoors, the ground source heat pump arranged on the ground, and a buried pipe arranged underground. One end of the indoor heat exchanger is connected with the ground source heat pump through a load side water pump and a load side water return pipe. The other end of the indoor heat exchanger is connected with the ground source heat pump through a load side water supply pipe. One end of the buried pipe is connected with the ground source heat pump through a ground source side water return pipe and a ground source side water pump. The other end of the buried pipe is connected with the ground source heat pump through a ground source side water supply pipe, and thus the indoor heat exchanger exchanges heat with the buried pipe through the ground source heat pump. The equipment has the beneficial effects that energy consumption of the ground source heat pump system is reduced, and the energy utilization efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of ground source heat pump heat exchange systems, in particular to shallow geothermal utilization equipment and a utilization method for improving the energy efficiency of ground source heat pumps. Background technique [0002] In recent years, ground source heat pump systems (GSHP) have been widely used in heating and cooling of buildings around the world. Compared with the traditional air conditioning system, the ground source heat pump system has higher thermal performance, because the ground source heat pump system uses the ground as a heat source in winter and uses a radiator in summer, the main reason is that the underground temperature remains stable, and the geological rock and soil mass Heat capacity is higher than that of air. Therefore, GSHP has great potential in terms of energy saving and CO2 emission reduction due to its high efficiency, but the main obstacles to the application of GSHP are hi...
