Abstract

The invention provides a ground source heat pump system for recovering the heat of wind in a tunnel, which relates to a ground source heat pump system. The invention aims to solve the self-contradictory problem that the prior underground tunnel carries the heat of wind out of the room and simultaneously uses other heat sources to supply heat for a station platform, thus energy sources are wasted.The ground source heat pump system also comprises a tunnel wind heat collecting device and a constant pressure device which are sequentially connected in series, wherein the tunnel wind heat collecting device is a loop formed by connecting a plurality of ground heat exchangers which are connected in parallel with a circulating water pump in series; the constant pressure device is formed by connecting a supplying water tank with a constant pressure supplying water pump in series; the liquid inlet end of each evaporator is connected with an inlet valve, and the liquid outlet end of each evaporator is connected with an outlet valve; the circulating water pump is communicated with the inlet valve; the heat pump, the inlet valve, the tunnel wind heat collecting device, the outlet valve and theheat pump are sequentially connected to form the loop; and the circulating water pump is communicated with the constant pressure supplying water pump through a pipeline. The ground source heat pump system is used for recovering the heat of the wind generated when the underground runs in the tunnel.

Description

technical field [0001] The invention relates to a ground source heat pump system. Background technique [0002] At present, subway vehicles will generate a lot of heat when they are running in underground tunnels. The heat is generally carried outdoors by the piston air, and at this time the temperature of the piston air can reach 40 degrees, which shows that a large amount of heat will be lost. In the severe cold areas in northern my country, the subway platform should be equipped with a heating system, and its heat source is generally the municipal heating external network. It can be seen from this that while bringing the generated heat to the outside by the piston wind, it is also necessary to use the municipal heating external network to provide heat for the platform, resulting in a great waste of energy. Contents of the invention [0003] The purpose of the present invention is to solve the paradoxical problem of energy waste that the existing underground tunnel brin...
