Abstract
The utility model discloses an underground water taking, recharging and heat-exchanging system for a water source heat pump air conditioning system, belonging to a heat-exchanging system. The system comprises a pumping well with a sealed cover, wherein the pumping well is internally provided with a submersible pump; the underground water extracted by the submersible pump is transported into a cyclone desander through a water taking pipeline; after the fine sands and the impurities in the water are removed, the water enters into a vacuum degasser, the well water enters into an energy extracting device after the gas is discharged by using the air release valve of the vacuum degasser; the well water the energy is extracted is dispersed into a recharging well with the sealed cover through a recharging pipeline; and the pumped well water is re-pumped after sufficiently changing the heat with the soil, and the steps are repeated in this way. The system has the beneficial effects that the conventional open type self-flow water taking is changed into the sealed type water taking, the open type self-flowing recharging is changed into the sealed type pressurizing recharging, and the concentrated water pumping, dispersing and recharging are adopted, so that the aims of the improvement of the water taking quantity and the whole recharging can be achieved.
Description
Technical field
The utility model relates to underground heat exchange system; Specifically be that a kind of water source heat pump air conditioning system recharges heat-exchange system with the underground water water intaking.
Background technology
Phreatic water has four seasons constant temperature characteristics, and as water source heat pump units heat exchange water source, refrigeration and heating can both obtain the higher energy efficiency ratio, is the comparatively general earth source heat pump form of using at present.Because existing water source heat pump system groundwater abstraction all is to adopt traditional open pumped well water intaking; Rely in the well water level to descend fully and the underground water standing level forms the pressure reduction water intaking of could flowing automatically; Water yield is limited by underground reservoir thickness and porosity, is difficult to get enough water yields in the relatively poor place of geological conditions.Because existing recharging technique mostly is to adopt open inverted well to recharge; Relying on the interior water level rising of inverted well could flow automatically with underground water standing level formation pressure reduction fully recharges; The amount of recharging is limited by underground permeable layer thickness and porosity not only; Also receive multiple effects limit such as underground water hydrostatic level buried depth, inverted well obstruction, underground reservoir obstruction, therefore, it is a difficult problem of generally acknowledging that the water intaking of water source heat pump system is recharged always.
Summary of the invention
For addressing the above problem, the utility model provides a kind of water source heat pump air conditioning system to recharge heat-exchange system with the underground water water intaking.
The utility model is realized with following technical scheme: a kind of water source heat pump air conditioning system recharges heat-exchange system with the underground water water intaking; It comprises pumped well that is embedded in underground band closing cap and the inverted well that seals well lid; Hydrocyclone, degasser, energy extraction device; Immersible pump is installed in pumped well, and immersible pump is connected with hydrocyclone, degasser, energy extraction device through the water intaking pipeline successively, and energy extraction device also is connected with inverted well through recharging pipeline.Described pumped well is that inverted well is many mouthfuls that are in parallel flatly.
Principle is: the immersible pump in the pumped well extracts well water and passes through the water intaking pipeline to hydrocyclone; After removing the fine sand and impurity in anhydrating, get into vacuum degassing machine, get into energy extraction device through the well water behind the air bleeding valve discharge gas of vacuum degassing machine; The well water that was extracted energy is sent in the inverted well through recharging pipeline; Behind abundant and soil heat exchange, extracted out again by pumped well, so circulation.
Owing to adopted technique scheme, water intake well is added removable sealed well lid, through immersible pump and vacuum degasser, when groundwater abstraction, make the vacuum that reaches certain in the pumped well, let be always negative pressure in the pumped well.Well water can be separated the silt in the well water through hydrocyclone, prevents that silt from blocking energy extraction device and inverted well; Well water gets into before energy extraction device and the inverted well, separates all gases in the well water through vacuum degasser, guarantees that heat transfer process and inverted well pressurize to recharge in the process can not produce vapour lock, does not have gas counter-pressure to recharge smoothly.Inverted well is added removable sealed well lid, guarantee that recharge system is air tight, guarantee to have when recharging to be not more than 1 kilogram pressure.Adopt the vacuum outgas function to let well water obtain vacuum outgas in water intake well and pipeline, adopt the eddy flow sand cleaning machine to separate the silt in the well water.Rely on pressurization to recharge and guarantee that well water all recharges.Adopt totally-enclosed form, well water is come recharge the underground process from taking-up and is not contacted with air.
The utility model good effect is: adopt above system, guarantee that well water does not contact with air from taking out to recharge the underground process, do not have oxidation reaction to keep water quality constant; In the water intake well is negative pressure, holds water level minimizing fall in the well, causes surface subsidence in order to avoid form hopper zone.Vacuum is drawn water and is with and pushes back filling, is convenient in the less fine sand layer of infiltration coefficient, draw water recharge; Be convenient to draw water and recharge in the very shallow place of groundwater level.
