In summer, the refrigerant in the refrigeration system carries out kind of refrigeration cycle by the order of evaporation → compression → condensation → expansion and realizes the air-conditioner refrigerating operaton; In the winter time, the then switching by four-way change-over valve, refrigerant carries out realizing the air conditioner heat-production operation with the reverse circulation that heats of kind of refrigeration cycle.Except common refrigerating/heating function, air-conditioner also has in the suction chamber contaminated air concurrently and becomes clean air after with its filtration, purification and be discharged into the indoor air purifying function again, and has and be discharged into indoor dehumidification function again after becoming dry air behind the humid air of suction.
Fig. 1 shows that the inside of general window air conditioner constitutes, and illustrates the operation of general air-conditioner as example.
As shown in Figure 1, the indoor heat converter 15 of window air conditioner is arranged at the rear of the indoor air entry that forms on the indoor front panel of air-conditioner body 30, and indoor heat converter 15 inside are provided with the copper tube of the refrigerant that flows.After the refrigerant that flows in the room air that sucks by indoor air entry and the copper tube carries out heat exchange, regulate its temperature and by indoor air outlet discharge.
When carrying out refrigerating operaton, indoor heat converter 15 has the evaporimeter effect, and the liquid refrigerants that flow in indoor heat converter 15 copper tubes is transformed to gaseous coolant through pervaporation, and absorbs the heat of room air.
The copper tube that connects indoor heat converter 15 connects four-way change-over valve 19, and four-way change-over valve 19 connects compressor 14.Four-way change-over valve 19 is used to modulate the flow circuit of refrigerant, and for example, when air-conditioner carried out refrigerating operaton, the refrigerant that spues in the modulation compressor 14 carried out kind of refrigeration cycle; When air-conditioner carries out heating operation, then modulate refrigerant and heat circulation.
The outside part of air-conditioner body 30 is provided with outdoor heat converter 16.The inside of outdoor heat converter 16 also is provided with the copper tube of the refrigerant that flows, and the HTHP gaseous coolant that spues in the compressor 14 will be by copper tube inlet chamber outer heat-exchanger 16.When carrying out refrigerating operaton, outdoor heat converter 16 has the effect of condenser, and the gaseous coolant of inflow will be transformed to liquid refrigerant through condensation.
Be provided with elongated expansion valve 18 between the conduit of junction chamber outer heat-exchanger 16 and indoor heat converter 15.When refrigerant passes through expansion valve 18, will become the state of low-temp low-pressure.
When air-conditioner carried out refrigerating operaton, refrigerant carried out kind of refrigeration cycle with the order of compressor 14 → outdoor heat converter 16 → expansion valve 18 → indoor heat converter 15, and reduced the indoor temperature in air conditioning space; When carrying out heating operation, then the order with compressor 14 → indoor heat converter 15 → expansion valve 18 → outdoor heat converter 16 heats circulation, emits heat and improves the indoor temperature in air conditioning space.
When carrying out refrigerating operaton, the indoor temperature in air conditioning space will be reduced to design temperature, and the reduction of indoor temperature can increase the relative humidity in air conditioning space.Relative humidity has the high more characteristic of the low more then humidity of space temperature.Therefore, the temperature of setting when refrigeration is low more, and indoor high humility can feel to bring uncomfortable sensation to the user more.
For reducing the increase of the space humidity that above-mentioned reason causes, air-conditioner can dehumidify operation to remove the moisture in the air conditioning space.The dehumidifying operation of air-conditioner is finished by refrigerant the flowing in indoor heat converter 15 that temperature remains on below the room air dew point.
Undertaken in the process of heat exchange by the room air of indoor heat converter 15 and the refrigerant of the following low temperature of dew point, its part will be liquefied and form trickle water droplet on the surface of indoor heat converter 15.After trickle water droplet focuses on one, discharge to the outside by the condensate draining pipe that indoor heat converter 15 bottoms are provided with.Thereby the room air with high humility is during through indoor heat converter 15, removes moisture and becomes dry air and reduce humidity in the air conditioning space thus.
Move the moisture that to remove in the air conditioning space by dehumidifying, but meanwhile, the temperature in the air conditioning space must be brought down below the temperature of setting, thereby cause other user to be not suitable for the generation of situation.
Therefore, need to develop the temperature that not only keeps in the air conditioning space be design temperature, but also can remove the air-conditioner with isothermal dehumidifying function of inner moisture.
Fig. 2 and Fig. 3 show that respectively the inside of the air-conditioner that has the isothermal dehumidifying function in the prior art constitutes and the schematic diagram of dehumidifying operation.
Air-conditioner inside with isothermal dehumidifying function shown in Figure 2 is provided with two discrete cover cooling cycle systems.The 1st cooling cycle system is made up of the 1st indoor heat converter the 50, the 1st compressor the 70, the 1st outdoor heat converter the 80, the 1st expansion valve 90; The 2nd cooling cycle system is made up of the 2nd indoor heat converter the 52, the 2nd compressor the 72, the 2nd outdoor heat converter the 82, the 2nd expansion valve 92.

And when air-conditioner carries out the isothermal dehumidifying operation, the refrigerant in the 1st cooling cycle system will carry out kind of refrigeration cycle with the order of the 1st compressor 70 → the 1st outdoor heat converter 80 → the 1st expansion valve 90 → the 1st indoor heat converter 50 → the 1st compressor 70; Refrigerant in the 2nd cooling cycle system then heats circulation with the order of the 2nd compressor 72 → the 2nd indoor heat converter 52 → the 2nd expansion valve 92 → the 2nd outdoor heat converter 82 → the 2nd compressor 72.
Refrigerant in two cooling cycle systems is when carrying out above-mentioned kind of refrigeration cycle respectively and heating circulation, in the room air that sucks by the indoor air entry of air-conditioner, moving air by the 1st indoor heat converter 50 carries out heat exchange with the low temperature refrigerant that connects the 1st indoor heat converter 50 and removes the moisture that comprises in it, then carries out heat exchange with the high temperature refrigerant that connects the 2nd indoor heat converter 52 by the 2nd indoor heat converter 52 flow air and compensates the temperature that is reduced by the 1st indoor heat converter 50.As mentioned above, the kind of refrigeration cycle that refrigerant in two cooling cycle systems carries out respectively simultaneously in the air-conditioner shown in Figure 2 and heat circulation and realize the operation of air-conditioner isothermal dehumidifying.
Cooling cycle system with two indoor heat converters is set in the air-conditioner with isothermal dehumidifying function shown in Figure 3, heat exchanger is connected with throttle expansion valve with compressor by a plurality of by-pass valve controls, form different refrigerant circulation paths, realize refrigeration, heat and isothermal dehumidifying operation heat.
Overlapped setting before and after two indoor heat converters of air-conditioner shown in Figure 3.First indoor heat converter 100 is arranged at the rear of air-conditioner front panel suction inlet, 110 rears that are arranged at first indoor heat converter 100 of second indoor heat converter.One side of two indoor heat converters 100,110 is connected to a side of first and second expansion valve 120,130, a side of the opposite side junction chamber outer heat-exchanger 140 of first and second expansion valve 120,130.
Simultaneously, a side of second indoor heat converter 110 also connects compressor 150 except that connecting second expansion valve 130.One side of compressor 150 connects a side of second indoor heat converter 110 and the opposite side of outdoor heat converter 140 respectively, and its opposite side connects the opposite side of first and second indoor heat converter 100,110 by four-way change-over valve 160.That is, be used for the conduit that refrigerant flows and will be divided into two from what a side of compressor 150 was come out, first conduit, 151 junction chamber outer heat-exchangers, 140, the second conduits 152 are connected in second indoor heat converter 110.
In addition, be provided with between second indoor heat converter 110 and second expansion valve 130 to be used to regulate then be provided with on first valve, 170, the second indoor heat converters 110 that refrigerant between the two flows and the second conduit 152 between the compressor 150 and regulate second valve 180 that refrigerant between the two flows.
The rear of second indoor heat converter 110 is provided with the indoor fan that is used to inhale, arrange room air, and the rear of outdoor heat converter 140 is provided with the fan of suction, emptying gas.
When air-conditioner carries out refrigerating operaton, from a side of first and second expansion valve 120,130 respectively to the liquid refrigerants of a side inflow low-temp low-pressure of first and second indoor heat converter 100,110, in indoor heat converter, evaporate, and the temperature in air conditioning space is reduced; When air-conditioner carries out heating operation, flow into the gaseous coolant of HTHP to the opposite side of first and second indoor heat converter 100 and 110 from the opposite side of compressor 150, condensation in indoor heat converter is carried out heat exchange and is improved the temperature in air conditioning space with room air.When carrying out the operation of aforesaid refrigerating/heating, open first valve 170, close second valve 180, make between second expansion valve 130 and second indoor heat converter 110 to communicate, then do not communicate between compressor 150 and second indoor heat converter 110.
When air-conditioner carries out isothermal dehumidifying, will close between first valve, 170, the second expansion valves 130 and second indoor heat converter 110 and not communicate; Open second valve 180, communicate and make between the compressor 150 and second indoor heat converter 110.Flow into the liquid refrigerants of low-temp low-pressures from a side direction first indoor heat converter 100 of first expansion valve 120, evaporation in first indoor heat converter 100, and the temperature in air conditioning space reduced.Simultaneously, a side direction second indoor heat converter 110 of compressor 150 flows into the gaseous coolant of HTHP, and condensation in second indoor heat converter 110 is carried out heat exchange and improved the temperature in air conditioning space with room air.Therefore, the room air that enters from the suction inlet of air-conditioner, during through first indoor heat converter 100, its moisture that includes will be liquefied and remove and become dry air; During through second indoor heat converter 110, the temperature that is reduced in the time of then can compensating through first indoor heat converter 100, thus room air is remained uniform temperature.That is to say, first indoor heat converter 100 is carried out the dehumidification function of removing the room air moisture, it is the intensification function of uniform temperature that 110 of second indoor heat converters are carried out the maintenance room air, and the operate together of two indoor heat converters makes air-conditioner carry out the isothermal dehumidifying function.
But the air-conditioner with isothermal dehumidifying function of the prior art that Fig. 2 and Fig. 3 show has following problem.
Air-conditioner shown in Figure 2 is provided with the cooling cycle system of two independent operatings.When isothermal dehumidifying, a cooling cycle system refrigerating operaton plays exsiccation; Another cooling cycle system heating operation plays the stable environment temperature.And the autonomous systems of two dehumidifying operations blow out cold wind and hot blast respectively, in indoor mixing to stablize room temperature.Therefore, there are shortcomings such as complex structure, manufacturing cost height in this air-conditioner.
Air-conditioner shown in Figure 3 is provided with an independently cooling cycle system.But when isothermal dehumidifying, the HTHP gaseous coolant that compressor is discharged is divided into two-way, and one the tunnel directly by indoor heat converter 110, and the condensation heat release improves indoor air themperature, gets back to compressor then; Outdoor heat converter, the 2nd expansion valve are passed through in another road, and in indoor heat converter 100 heat absorption dehumidifying, return compressor.
Therefore, the cooling cycle system of above-mentioned air-conditioner shown in Figure 3 existing problems are:
(1) refrigerant carries out two circulations, has disperseed coolant quantity, and compressor is directly got back in the phase transformation of not freezing of a part of refrigerant, reduces the efficient of compressor.
(2) one road refrigerants will pass through throttling expansion, and flow resistance is big, and the flow resistance on another road is less, and it is uneven that this will make refrigerant distribute, and lowers dehumidifying effect.And, indoor heat converter 110 side refrigerant pressure height, indoor heat converter 100 lateral pressures are low, may produce the coolant backflow phenomenon, can make system's fluctuation of service.
