Abstract

The invention relates to a ground source heat pump system, which is applied in the technical field of geothermal energy utilization, which includes a heat exchange tube group, a first circulation pump, a ground source heat pump unit, a water heater, a coil pipe and a second circulation pump, and a heat exchange tube group Buried in the soil and connected to the first circulating pump through the first water pipe, the first circulating pump is connected to the ground source heat pump unit through the first branch pipe, and the ground source heat pump unit is connected to the water inlet end of the coil through the second water pipe. Buried in the building room, the outlet end of the coil pipe is connected to the second circulation pump through the second branch pipe, and the second circulation pump is connected to the heat exchange tube group through the return pipe. The present invention has the effect of accelerating temperature rise when heating indoors.

Description

technical field [0001] The invention relates to the technical field of utilization of geothermal energy, in particular to a ground source heat pump system. Background technique [0002] Ground source heat pump technology is a new type of central air-conditioning system that uses renewable energy for heating, using shallow and deep earth energy, including soil, groundwater, and surface. [0003] The Chinese patent with the notification number CN206449782U discloses a ground source heat pump system, including an air conditioning system, a ground source heat pump host and a soil heat exchanger, and also includes an indoor side circulation pump, a ground source side circulation pump, the first ground source heat pump host and The second ground source heat pump host. [0004] However, in the actual process of heating the room, since the water only relies on geothermal heat in the heat exchange cycle, it takes a certain amount of time to reach the required temperature in the init...
