Abstract

A geothermal energy resources heat pump system consists of an evaporator, a condenser, a compressor and an expansion valve and they are connected one by one to form a heat-exchanging unit. The evaporator and the condenser are connected with the well-water pipeline separately via the valve set and the indoor circulating water pipeline. In the process of heating in winter and refrigerating in summer switching the valve set separately can make the indoor circulating water and the well water flow through the evaporator or the condenser separately according to the needs.

Description

technical field [0001] The invention relates to refrigeration and heating technology, in particular to ground source heat utilization equipment, in particular to a ground source heat pump system. Background technique [0002] In the prior art, the air-cooled (hot) water unit is used for heating or cooling of buildings, and the air-cooled (hot) water unit will have difficulty starting when the outdoor temperature is as low as -8°C, and it is necessary to increase the air-cooled heat pump. Auxiliary electric heating increases the energy consumption of the system. Contents of the invention [0003] The purpose of the present invention is to provide a ground source heat pump system. The ground source heat pump system described in the prior art should solve the problems of the air-cooled (hot) water unit in the prior art that it is difficult to start at low outdoor temperatures and the energy consumption of auxiliary electric heating needs to be increased. technical problem. ...
