The two embodiments the difference is that, in first embodiment shown in Fig. 1, dehumidification system 3 removes for solution
Wet system, namely dehumidification treatments are carried out to air using solution；And in a second embodiment shown in figure 2, dehumidification system 3 is to turn
Dehumidification system is taken turns, is that dehumidifying and regeneration treatment are carried out to air by runner 34.
As shown in Figure 1, in the first of the present invention implements, it is additionally provided with dehumidification device 32 in the heat transfer loop that dehumidifies, dehumidifying is changed
Thermal medium is solution, and solution, which flows through, states heat transfer medium heater 31 after the refrigerant absorption heat flowed out by air conditioner loop by dilute molten
Liquid becomes concentrated solution, and concentrated solution flows through dehumidification device 32 and carries out dehumidification treatments to indoor air inlet.
Next the operation principle of the first embodiment air-conditioning system is illustrated such as so that air conditioner loop is refrigeration cycle as an example
Under：
(1) after indoor unit 2 is opened, if there is dehumidification, the high temperature refrigerant of the outlet of compressor 11 of multi-joint outdoor unit 1
A part enters the outdoor condensation of radiator 14 heat dissipation, and the cold medium flux of this part can pass through the first electric expansion valve EXV1 controls
System；Another part enters heat transfer medium heater 31 and directly heats weak solution, by the moisture evaporation in weak solution, solution is made to become
Concentrated solution, later concentrated solution flow through dehumidification device 32 to indoor air inlet carry out dehumidification treatments, complete dehumidification process, this part refrigerant
Break-make controlled by the first solenoid valve 41, flow then by third electric expansion valve EXV2 control.
(2) if without dehumidification, by the first solenoid valve 41, second solenoid valve 61 and third electric expansion valve EXV3
It closes, cut-out is passed through the refrigerant of heat transfer medium heater 31, and multi-joint outdoor unit 1 can be transported as common multi-joint outer machine at this time
Row.
(3) it if in low temperature or underload, due to being stored with a large amount of liquid refrigerants in gas-liquid separator 12, changes
Thermal effect is poor, and refrigerant evaporation amount is less, it will has a large amount of refrigerant to reside in gas-liquid separator 12, causes system circulation cold
Matchmaker, which measures, to be reduced, at this point, third solenoid valve 71 is opened, then compressor 11 exports high temperature refrigerant some can be introduced into heating
Exothermic condensation in coil pipe 123, the interior liquid refrigerants accumulated of heating gas-liquid separator 12, which is sucked after so that it is evaporated by compressor, to be compressed,
To increase the refrigerant circulation of air-conditioning system, improve the operation conditions of air-conditioning system.
As shown in Fig. 2, in the second embodiment of the present invention, it is additionally provided with radiator 33 on the heat-exchanging loop that dehumidifies, dehumidifying is changed
Thermal medium flows through after heat transfer medium heater 31 absorbs heat from the refrigerant flowed out by air conditioner loop and flows through radiator 33 with to again
Raw air heating, the regenerator section that the runner 34 of dehumidification system 3 is entered by the regeneration air that radiator 33 heats carry out regeneration treatment.
And as shown in Figure 2, in this embodiment, dehumidification system 3 further includes fan 35, in order to which the regeneration that will be heated by radiator 33 is empty
Air-blowing enters the regenerator section of runner 34.
Next the operation principle of the first embodiment air-conditioning system is illustrated such as so that air conditioner loop is refrigeration cycle as an example
Under：
(1) after indoor unit 2 is switched on, if there is dehumidification, the high temperature refrigerant of the outlet of compressor 11 of multi-joint outdoor unit 1
A part of gas enters the condensation heat dissipation of outdoor radiator 14, and the cold medium flux of this part can pass through the first electric expansion valve EXV1 controls
System；Another part enters heat transfer medium heater 31 and exchanges heat with the dehumidifying heat transfer medium for entering radiator 33, and radiator 33 heats
After air, hot-air is blown into the regenerator section of runner 34 by fan 35, realizes rotary wheel dehumidifying regeneration, the break-make of this part refrigerant is by the
One solenoid valve 41 controls, and flow is controlled by third electric expansion valve EXV3.
(2) if without dehumidification, by the first solenoid valve 41, second solenoid valve 61 and third electric expansion valve EXV3
It closes, cut-out is passed through the refrigerant of heat transfer medium heater 31, and multi-joint outdoor unit 1 can be transported as common multi-joint outer machine at this time
Row.
(3) it if in low temperature or underload, due to being stored with a large amount of liquid refrigerants in gas-liquid separator 12, changes
Thermal effect is poor, and refrigerant evaporation amount is less, it will has a large amount of refrigerant to reside in gas-liquid separator 12, causes system circulation cold
Matchmaker, which measures, to be reduced, at this point, third solenoid valve 71 is opened, then compressor 11 exports high temperature refrigerant some can be introduced into heating
Exothermic condensation in coil pipe 123 makes its evaporation to the liquid refrigerants heat release in gas-liquid separator 12, is evaporated to gaseous refrigerant and then can
Enough sucked by compressor is compressed, and to increase the refrigerant circulation of air-conditioning system, improves the operation conditions of air-conditioning system.
As it can be seen that the air-conditioning system of the two embodiments, regenerates and evaporates gas-liquid using the exhaust of compressor 11 as dehumidifying
The heat source of the liquid refrigerants accumulated in separator 12 not only solves multi-online air-conditioning system in the prior art and does not have dehumidifying work(
The insufficient problem of liquid refrigerants evaporation in energy and gas-liquid separator 12 so that air-conditioning system has can independent control but also connection
The refrigeration and heat-production functions and dehumidification function of dynamic control ensure that refrigerant fully participates in recycling, and make being vented for compressor 11
More fully to utilize, can the effectively save energy, improve the functional reliability of air-conditioning system.
The foregoing is merely exemplary embodiment of the present invention, are not intended to limit the invention, all spirit in the present invention
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
