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
The present invention relates to a kind of earth-source hot-pump system.
Background technology
Railcar can produce a large amount of heats in the subterranean tunnel driving process at present, and these heats are generally taken to outdoor by piston wind, and the temperature of piston wind can reach 40 degree at this moment, this shows a large amount of losses that can cause heat.And at the northern China severe cold area, subway platform should be provided with heating system, and its thermal source is generally municipal heating power outer net.This shows, the heat that produce by piston wind taken outdoor on one side, also need utilize municipal heating power outer net to be the platform heat supply on one side, thereby cause the significant wastage of energy.
Summary of the invention
The objective of the invention is to take to outdoorly, use this self-contradictory energy waste problem of other thermal source simultaneously, proposed a kind of earth-source hot-pump system that reclaims tunnel wind-heat amount as the platform heating in order to solve heat that existing subterranean tunnel keeps watch.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: described earth-source hot-pump system comprises the heat pump of a plurality of parallel connections, each heat pump is by evaporimeter, compressor, the loop that condenser and expansion valve are composed in series successively, described earth-source hot-pump system also comprises tunnel wind-heat amount harvester and the constant pressure arrangement that is cascaded successively, the loop that described tunnel wind-heat amount harvester is composed in series for ground pipe laying and water circulating pump by a plurality of parallel connections, described constant pressure arrangement is in series by extra feed tank and level pressure make-up pump, the liquid feeding end of each evaporimeter is connected with inlet valve, the outlet end of each evaporimeter is connected with outlet valve, described recirculated water delivery side of pump is communicated with inlet valve, described heat pump, inlet valve, tunnel wind-heat amount harvester, outlet valve and heat pump constitute the loop, and the import of described water circulating pump is communicated with the level pressure make-up pump by pipeline.
The present invention has following beneficial effect: 1. the present invention is used for subway platform heating by the heat that reclaims tunnel wind, thereby has improved capacity usage ratio.2. the invention solves on one side the heat of tunnel wind is taken to outdoor, Yi Bian this self-contradictory energy waste problem of using other thermal source to heat as platform.3. pipe laying is embedded in the both sides, tunnel, can carry out pipe laying when subway work stage tunneling, and easy construction does not increase construction cost substantially.
