Summer environment is mostly high temperature and humidity weather, and the present invention can accomplish independent temperature-humidity control, and energy consumption is main
For solar energy, comfort requirement and craftsmanship requirement are also met while saving energy.
Air-conditioning system of the present invention is mainly dehumidified subsystem and solar energy absorption type refrigeration subsystem (including refrigerant by coating solution
Water subsystem) it constitutes.
Coating solution dehumidification system working principle is as follows：
The dehumidification solution and outdoor air of low temperature and high concentration simultaneously flow through film dehumidifier, due to its solution surface vapour pressure compared with
It is low, and outdoor air relative humidity is higher, steam partial pressure is also higher, and then part vapor penetrates film by solution in air
It is absorbed, reaches wet down effect.It flows out the solution of film dehumidifier and is lower because absorbing a large amount of water vapor concentrations, lose dehumidifying energy
Power, and flow into condenser and heated, and heat source is the heat that refrigerant condensation is put in absorption refrigeration subsystem.By adding
Hot dehumidification solution flows into regenerator after reaching regeneration temperature, and solution temperature at this time is higher, and solution surface vapour pressure is also higher,
With indoor return air carry out it is wet exchange, vapor is discharged outdoor from being transferred in the lower air of relative humidity in solution.From
For the solution of regenerator outflow because moisture tails off, concentration is increased to initial concentration, first flows through third heat exchanger, normal-temperature water is to high temperature
Dehumidification solution is pre-chilled, and flows through the second heat exchanger later and chilled water carries out heat exchange cooling, the solution after temperature reduces restores
Dehumidifying effect is stored in dehumidification solution reservoir, can be pumped by dehumidification solution and is drawn into film dehumidifier progress circulating dehumidification.

Solar thermal collector absorbs solar energy and is stored in hot water, and is added by the control of the first water pump to generator
Heat.Refrigerant concentration is higher in generator, by the high-temperature high-pressure refrigerant gas overflowing after heating, and it is cold by condenser
But highly pressurised liquid is condensed into, the heat of releasing is used for heating and dehumidification solution.High pressure refrigerant liquid throttles by first throttle valve
Become low temperature and low pressure liquid and its steam mixture, and flows into evaporator, low-temperature low-pressure refrigerant liquid vaporization absorption therein
The heat of chilled water, so that chilled water temperature reduces.The refrigerant vapour flowed out from evaporator is absorbed refrigerant concentration in device
Lower solution absorbs, and solution temperature increases in absorption process, needs to be cooled down by cooling tower to guarantee its absorbability,
This process is controlled by the second water pump.Mixture refrigerant concentration after absorbing refrigerant vapour increases, through absorbent solution
Pump and solution heat regenerator flow back to generator.And the lower solution of refrigerant concentration formed after heating in generator is by solution
Inflow absorber after heat regenerator and second throttle cooling, completes circulation.
Chilled water subsystem work principle is as follows：
Chilled water flows into First Heat Exchanger after evaporator cools down and flows through the hot friendship of outdoor air progress of film dehumidifier
It changes, it is heat-treated, the chilled water after outflow, which enters dehumidification solution of second heat exchanger further and by pre-cooling, to carry out

Institute's calorific requirement is provided by solar energy absorption type refrigeration subsystem completely, and temperature-fall period institute's chilling requirement is by cooling water, solar absorption
Formula refrigeration subsystem provides jointly.Reach after humidity requires by the air of film dehumidifier using absorption refrigeration subsystem simultaneously
Chilled water in system carries out Temperature Treatment, then discharges into interior by the first blower, and therefore, outdoor air can realize temperature through this system
Humidity-independent control, and the required energy is mainly from solar energy.
Compared with prior art, the present invention has the following advantages and beneficial effects：
First, it is separately adjustable that the present invention compared to general air-conditioning system can preferably carry out temperature and humidity, avoids routine
Air-conditioning is because of the case where can not meeting indoor temperature and humidity demand simultaneously sometimes.In addition, solution dehumidification application so that humidity regulation more
Increase effect, environmental protection；The application of membrane separation technique efficiently solves the problems, such as to carry dehumidification solution drop in dehumidified air secretly.
Second, the present invention has better energy saving compared to general temperature and humidity autonomous system, and coating solution is dehumidified subsystem
System and solar energy absorption type refrigeration subsystem are effectively combined, the heat discharged using condenser in absorption refrigeration subsystem
Heating and dehumidification solution, the cooling air for entering room of cooling capacity discharged using evaporator in absorption refrigeration subsystem.In addition, this
In invention in addition to the devices such as cooling tower, blower and pump need to consume a small amount of electric energy, entire air-conditioning system is only driven by solar thermal energy,
Meet the trend that current using energy source changes to renewable energy.
Third, the present invention in energy utilization more sufficiently, efficiently.High temperature regeneration solution is carried out by normal-temperature water pre-
Cold, the chilled water after processed air themperature is used further to further cool down to actified solution, and indoor return air is for dehumidification solution
But also entire air-conditioning system is more independent while making full use of the energy, operation and control are easy for the measures such as regeneration.
