He is arranged in evaporator 1 distribution form, such as combination, combination of M and M of W and V etc..
In high altitude localities, because local atmospheric density is only the 50%~60% of sea level, the layout of above-mentioned fin component
Structure ensure that so that the evaporator 1 of net for air-source heat pump units provided by the invention increases the heat exchange area with mine return air
Flow does not subtract, and meets the demand of mining area waste heat recycling system.
Further, as shown in Fig. 2, every row's fin component may include evaporation tube 11 and multiple spaced fins
12.Spacing between two adjacent fins 12 is d, and the numerical value of d can be 3-6mm, for example, 3.5mm, 4mm, 4.5mm, 5mm,
5.5mm waiting.
Further, the spacing between two adjacent fins 12 can be 4-5mm.
Further, the spacing between two adjacent fins 12 can be 4.2mm.
Specifically, the spacing between the two adjacent fins of evaporator 1 is 1.8mm in the prior art, and the application is by wing
Spacing between piece 12 increases, and can reduce dust in air and be attached to 12 surface of fin, influence the heat absorption efficiency of fin 12.Together
When, the spacing between fin 12 increases, and also reserves enough spaces for staff, scrubs fin 12 for cleaning means.
Further, above-mentioned refrigerant pipe can be copper pipe.Selecting copper refrigerant pipe to have, at low cost, quality is soft, pliable
The advantages that bent.Meanwhile copper refrigerant pipe is mounted in heat exchange equipment, lighter in weight and corrosion-resistant.
Further, heat pump main frame 2 further includes control cabinet, for controlling the operation of net for air-source heat pump units of the invention,
Such as temperature control, defrosting control etc..
The present invention also provides a kind of return air residual heat in mine recovery systems, are equipped with above-mentioned net for air-source heat pump units.At this
In embodiment, return air residual heat in mine recovery system further includes air ducting, hot water transportation and distrubution apparatus and thermal water utilization device.
Specifically, the well head of air duct one end connection mine return air of air ducting, the other end in air duct connects above-mentioned
The evaporator 1 of net for air-source heat pump units.Air ducting guides mine return air to evaporator 1, for absorbing in mine return air
Waste heat.
Hot water transportation and distrubution apparatus includes hot water feeding pipe and hot water return pipe, one end of hot water feeding pipe and hot water return pipe
The condenser 22 of net for air-source heat pump units is connected, the other end connects thermal water utilization device.
Further, which can be mine air inlet preheating device and/or shower bath and/or heating dress
It sets.It is of course also possible to be other thermal water utilization devices, no longer it is described in detail herein.
Further, the installation site interval of the installation site of evaporator 1 and heat pump main frame 2 is arranged, so that evaporator 1
It is suitable for the specific structure of air ducting, and the air opening end of the air ducting is set.Heat pump main frame 2 is far from evaporator 1
Installation site, without heat pump main frame 2 to be similarly installed to the air opening end of air ducting.Such structure design, saves
The installation space of air ducting reserves enough installation sites for evaporator 1；Meanwhile reducing the installation difficulty of integral device.
Further, hot water transportation and distrubution apparatus can also include water replanishing device, for supplementing return air residual heat in mine of the invention
Recirculated water in recovery system.
In addition, hot water transportation and distrubution apparatus can also include water softening device to reduce the hardness of mining area recirculated water comprising tree
Rouge tank and salt box.Resin container is used to remove the calcium ions and magnesium ions in tap water, softens to water.Salt box can provide salt water, use
To pass through resin container, so that resin container restores softening function of exchange.
Specifically, tap water is introduced into resin container, and resin container cements out the calcium ions and magnesium ions in tap water.Work as resin
After tank absorbs a certain amount of calcium ions and magnesium ions, the efficiency of resin removal calcium ions and magnesium ions is gradually reduced, therefore need to be regenerated.Regenerative process
It is exactly to be cemented out the calcium ions and magnesium ions on resin by resin with the salt water in salt box, is discharged outside resin container, so that resin is extensive
Soften function of exchange again.
It should be appreciated that the present invention is not limited in its application to the detailed construction and arrangement of the component of this specification proposition
Mode.The present invention can have other embodiments, and can realize and execute in many ways.Aforesaid deformation form and
Modification is fallen within the scope of the present invention.It should be appreciated that this disclosure and the present invention of restriction extend in text
And/or it is mentioned in attached drawing or all alternative combinations of two or more apparent independent features.It is all these different
Combination constitutes multiple alternative aspects of the invention.Embodiment described in this specification illustrates to become known for realizing the present invention
Best mode, and will enable those skilled in the art using the present invention.
