Description
Technical field
The present invention relates to the dehumidification equipment of field of air conditioning, especially relate to the double low-temperature receiver solution dehumidification unit of a kind of ground source heat pump type.
Background technology
In filed of air conditioning, typically require the air come in outdoor summer and carry out cool-down dehumidification process, typically require right winter
The air come in outdoor carries out warming and humidifying process.Traditional air conditioning system uses dehumidification by condensation processing mode mostly, i.e. uses
The cooling water of low temperature prepared by refrigeration machine, and logical supercooled water circulates in the coil pipe of surface cooler and carries out heat exchange, by sky with air
Temperature is reduced to below dew point, so that air condenses out moisture and realizes the dehumidification treatments for new wind.This processing mode
Dehumidifying and temperature-fall period are integrated and control and carry out simultaneously, due to cold far below needed for cooling of the cooling water temperature of dehumidification requirements
But coolant-temperature gage, causes the property of refrigeration machine by usually 7～12 DEG C, on the one hand, in the case of making refrigeration machine be operated in low evaporating temperature
Energy coefficient is relatively low, and on the other hand, though the air humidity after dehumidification by condensation meets requirement but temperature is too low, typically also needs to reheating
Wind pushing temperature requirement can be reached, cause the secondary waste of the energy.Further, since the existence condensing water makes surface cooler coil pipe etc.
It is easy to breed bacteria, goes mouldy, thus reduce air-supply quality, have a strong impact on the quality of room air.
For the defect overcoming traditional air-conditioning system dehumidification by condensation mode to exist, those skilled in the art has researched and developed solution humidifying
Mode, i.e. uses and has the saline solution of damping character as working media, directly contact with new wind and carry out caloic exchange, working as sky
When the partial pressure of water vapor of gas is higher than the surface vapor pressure of saline solution, saline solution is absorbed by the moisture in air；And when air
When partial pressure of water vapor is less than the surface vapor pressure of saline solution, the operative liquid water in saline solution is changing to gaseous state and enters in air,
Thus realize the regulation purpose to air humidity.Solution dehumidification mode is compared with the dehumidification by condensation mode of legacy system, it is not necessary to mistake
The low-temperature receiver of low temperature (7～12 DEG C), for utilizing resource low-grade energy widely to create condition；And in solution dehumidification mode
Saline solution directly contacts with air and carries out heat and mass, by the filtration of saline solution, sterilizing function, can remove in air
Dust, antibacterial, mycete and some other harmful substance, can be effectively improved air-supply quality and the quality of room air.Use solution

In this heat exchange mode, saline solution sprays the heat exchanger that filler that middle part arranges is tower from the sprinkler part on top, and under
Portion arranges saline solution collection box in order to reclaim saline solution, and during this one, air directly contacts with saline solution and conducts heat
Mass transfer, it is achieved saline solution is to the dehumidifying of air or adds wet process, saline solution realizes regeneration by closed circuit simultaneously, and with this kind
Mode iterative cycles runs.But the air conditioning system using this heat-insulating solution dehumidification device and regenerative device of solution generally exists

It is known that saline solution only just has preferable dehumidifying effect in the case of low temperature and high concentration, once saline solution
Temperature raises or concentration reduction all can affect effect on moisture extraction and dehumidification rate；Similarly, saline solution in the case of high temperature low concentration,
By with air contact could the saline solution of regeneration high concentration effectively, otherwise can affect saline solution regeneration effect and efficiency.?
Solution dehumidification or the process of humidification, can there is the release of latent heat of phase change while carrying out heat and mass or absorb in air and saline solution
Journey, makes the temperature of air and solution that Rapid Variable Design to occur simultaneously, and this change exactly suppresses or reduce mass transfer force, as
In time latent heat of phase change can not be passed or eliminate, can largely affect solution dehumidification and the effect of solution regeneration and efficiency.
Phase transformation, due to the defect of self structure, exactly can not quickly be dived by the saline solution dehydrating unit of employing heat-insulating and regenerative device of solution
Heat transfers or eliminates, and this field solves the main way of this problem and is to increase the usage amount of saline solution at present, in order to suppression or dilute
Release air and carry out the latent heat of phase change of generation in heat and mass transfer process with saline solution, although this processing mode alleviates in certain journey
The adverse effect of latent heat of phase change, but do not tackle the problem at its root, due to hygroscopicity its price of preferable saline solution the most all
Relatively higher, virtually increase operation cost, and make the operational factor of total system and precision wayward, on the other hand by
Relatively big in the usage amount of saline solution, will also result in overall unit and strengthen, increase manufacturing cost.The saline solution of the most this heat-insulating
The heat exchanger of dehydrating unit and regenerative device of solution mainly uses the relatively noble metal material manufacture such as copper, steel alloy, and its manufacturing cost is also
Of a relatively high.Additionally, use the air conditioning system of solution dehumidification mode at present, it is saline solution dehumidifying and regeneration mainly by heat pump
Link provides energy support, and its energy consumption is of a relatively high, makes the COP of total system relatively low.

Under dehumidifying operating mode summer, solution dehumidification regeneration cycle loop is in running, and the saline solution of low temperature and high concentration is at solution
During Dehumidifying element sprays, directly contact with by new wind therein and carry out hot and humid area, the water in this stylish wind
Vapor partial pressure power is higher than the surface vapor pressure of saline solution, and new wind is carried out at dehumidifying by the moisture that saline solution can absorb in new wind from realization
Reason, and the saline solution of high concentration is owing to absorbing the moisture in new wind thus concentration reduction.Then by circulating pump from solution dehumidification
The second solution spraying device that the first liquor box in unit is transported in solution regeneration unit, sprays in solution regeneration unit
During pouring, directly contacting and carry out hot and humid area with by return air therein, now the partial pressure of water vapor in return air is less than salt
During the surface vapor pressure of solution, the operative liquid water in low concentration salt solution can become gaseous state and enter in return air, simultaneously by second
Heat-exchanger rig heats, and makes the saline solution of saline solution regeneration high-temperature high concentration, then by the heat exchanger on this closed circuit
The saline solution making high-temperature high concentration becomes the saline solution of low temperature and high concentration, finally by another circulating pump by molten for the salt of low temperature and high concentration
Liquid is transported to the first solution spraying device of solution dehumidification unit and sprays, and such iterative cycles runs.
In the running of solution heat recovery cycle loop, saline solution is sprayed by the 3rd spray equipment of bottom heat regenerator,
Directly contacting with by new wind therein during spray and carry out hot and humid area, the thermal temperature of the new wind of salt-solution absorption raises,
Then saline solution temperature raised by solution circulation pump is transported to top heat regenerator from the 3rd liquor box of bottom heat regenerator
3rd spray equipment, directly contacts with by return air therein during spray and carries out hot and humid area, and return air takes away saline solution
In heat, saline solution temperature reduces, then flows to the 3rd spray of bottom heat regenerator from the 3rd liquor box of top heat regenerator
Shower device, such iterative cycles runs.
In earth source heat pump closed circuit running, subsoil water or river, lake, marine deep water are natural cold source, by source, ground
Heat pump cycle constantly the first heat-exchanger rig in solution dehumidification unit is passed through low-temperature receiver, takes away in time in saline solution dehumidification process and produces
Raw latent heat of phase change (now the moisture in air can release heat because becoming liquid), and heat is transported to underground, can effectively keep away
Exempt from the temperature in saline solution dehumidification process to raise, make the temperature levels that saline solution maintenance is relatively low, keep long-acting dehumidifying effect.
In the running of heat pump cycle loop, on the one hand at condenser, carry out heat exchange, continuously with heat transfer self circular loop
Thering is provided thermal source to the second heat-exchanger rig, (now the moisture in saline solution is because becoming for the latent heat of phase change produced in make-up solution regenerative process
Become gaseous state can absorb heat), the temperature being avoided that in saline solution regenerative process reduces, and makes the temperature levels that saline solution maintenance is higher,

Adding in the winter time under wet cooling condition, the heat exchange direction in saline solution closed circuit and the heat exchange circulation loop operating mode that dehumidifies with summer is contrary.
Solution dehumidification regeneration cycle loop is in running, and the saline solution of high temperature low concentration carries out spray process in solution dehumidification unit
In, directly contact with by new wind therein and carry out hot and humid area, the partial pressure of water vapor in this stylish wind is less than saline solution
Surface vapor pressure, the operative liquid water in high temperature low concentration salt solution can become gaseous state and enter in new wind, thus realize new wind
Add wet process, and saline solution enters in new wind thus concentration raises owing to operative liquid water therein becomes gaseous state.Then by following
Saline solution is transported to the second solution spraying device of solution regeneration unit by ring pump from the first liquor box of solution dehumidification unit, molten
During liquid regeneration unit sprays, directly contact and carry out hot and humid area with by return air therein, now in return air
When partial pressure of water vapor is higher than the surface vapor pressure of saline solution, saline solution can absorb the moisture in return air thus realize low concentration regeneration.
By the heat exchanger on this closed circuit, the saline solution of low-temperature and low-concentration is become the saline solution of high temperature low concentration subsequently, and by another
The saline solution of high temperature low concentration is transported to the first solution spraying device of solution dehumidification unit by one circulating pump.So iterative cycles fortune
OK.It should be noted that add in the winter time under wet cooling condition, the most only tend not to meet low by the moisture in salt-solution absorption return air
The regeneration requirements of concentration saline solution, need to supplement a certain amount of water by water compensating valve and can meet the low concentration requirement of saline solution.
In the running of solution heat recovery cycle loop, saline solution carries out spraying also by the 3rd spray equipment of bottom heat regenerator
Carrying out hot and humid area with directly being contacted by new wind therein, new wind absorbs the heat in saline solution, makes saline solution temperature reduce,
Then from the 3rd liquor box of bottom heat regenerator, saline solution is transported to top recuperation of heat by the solution circulation pump in this closed circuit
3rd spray equipment of device, carries out spraying and carrying out hot and humid area with directly being contacted by return air therein in the heat regenerator of top,
Heat in salt-solution absorption return air and temperature raises, flow to bottom recuperation of heat from the 3rd liquor box of top heat regenerator the most again
3rd spray equipment of device, such iterative cycles runs.
In earth source heat pump closed circuit running, subsoil water or river, lake, marine deep water are natural thermal source, by source, ground
Heat pump cycle constantly the first heat-exchanger rig in solution dehumidification unit is passed through thermal source, and the saline solution of spray is carried out heat make-up
The latent heat of phase change (now the aqueous water in saline solution become gaseous state can absorb heat) produced in solution humidification, makes saline solution tie up
Hold higher temperature levels, keep long-acting humidification capability.
In the running of heat pump cycle loop, heat pump cycle loop changes the flow direction of refrigeration working medium by four-way changeover valve, the coldest
Condenser plays vaporizer effect, and vaporizer then plays condenser effect, by the circular flow in heat pump cycle loop, on the one hand cold
At condenser, the heat transfer self circular loop with the second heat-exchanger rig carries out heat exchange, provides low-temperature receiver to the second heat-exchanger rig continuously,
