Description

Reclaim the earth-source hot-pump system of tunnel wind-heat amount
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.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1, the earth-source hot-pump system of present embodiment comprises the heat pump 11 of a plurality of parallel connections, each heat pump 11 is by evaporimeter 1, compressor 2, the loop that condenser 3 and expansion valve 4 are composed in series successively, described earth-source hot-pump system also comprises tunnel wind-heat amount harvester 12 and the constant pressure arrangement 13 that is cascaded successively, the loop that described tunnel wind-heat amount harvester 12 is composed in series for ground pipe laying 8 and water circulating pump 5 by a plurality of parallel connections, described constant pressure arrangement 13 is in series by extra feed tank 7 and level pressure make-up pump 6, the liquid feeding end of each evaporimeter 1 is connected with inlet valve 9, the outlet end of each evaporimeter 1 is connected with outlet valve 10, the outlet of described water circulating pump 5 is communicated with inlet valve 9, described heat pump 11, inlet valve 9, tunnel wind-heat amount harvester 12, outlet valve 10 and heat pump 11 constitute the loop, and the import of described water circulating pump 5 is communicated with level pressure make-up pump 6 by pipeline.
The position of described ground pipe laying 8 is around the tunnel cross section, and the form of employing is U-shaped pipe or snake pipe.
Operation principle: when platform need heat, when the tunnel wind of high temperature passes through the tunnel, by forced-convection heat transfer, the heat transferred surrounding soil, thereby further pass to the ground pipe laying 8 that is embedded in the subway tunnel both sides, this moment by water circulating pump 5 these heat transferred evaporimeters 1, as the low-temperature heat source of heat pump 11.Further by heat pump heat is risen to condenser 3 from evaporimeter 1 then, passing to needs the platform of heating room.Constant pressure arrangement 13 plays the effect of supply quantity of circulating water and level pressure.
