First embodiment that the present invention discloses has plurality of operating modes, wherein Fig. 1 can reflect the state with pattern one operation, among Fig. 1, the drop front 16 that can open fits tightly with the housing 9 of indoor set, the first auxiliary air inlet 14 is in closure state, this moment, heat exchanger 6 was not worked, also promptly by compressor in the off-premises station, outdoor heat exchanger, throttling arrangement (is a prior art, among the figure and not shown) and the refrigerating/heat pump system that formed of heat exchanger 6 do not move, heat exchanger 6 is air-treatment function not, electrostatic precipitation layer 4 in the air cleaning unit powers up, and promptly has DC voltage between discharge electrode 4A and the dust collecting electrode 4B, and the control of dust dust removing effects is arranged.The muddy air 10 of room air is at air inlet 2, each filter course through air cleaning unit 20, promptly, discharge from air outlet 8 by blower fan 7 pressurizations, become clean air 11 through the pure air that fully filters successively by filter course 3, electrostatic precipitation layer 4 and Combined Processing layer 5.

Because when indoor machine of air-conditioner is moved according to pattern one, have only electrostatic precipitation layer 4 and blower fan 7 energising work, electricity consumption situation when moving with the common air-conditioning device has bigger different, with 1.5 air-conditionings is example, when normal refrigerating operaton, the power consumption of compressor+blower fan+electrostatic precipitator will be far longer than an employing pattern one dedusting air vent mode.As shown in figure 13, when adopting common refrigeration+dedusting pattern, operate power is 1104 watts, if employing pattern one, i.e. dedusting air vent mode, the power of indoor high rotating speed operation has only 50 watts, air output per hour can reach 600 cubic metres, for the room that adopts 1.5 air-conditionings, this air quantity makes room ventilation quantity hourly can reach 10, generally there is no need to select so big; In order to reach the state that the user is suitable for, can select lower wind speed, can reach the indoor air-changing air-conditioning requirement, further reduce noise, adopt the actual motion power of low wind speed to have only 35 watts, energy consumption is also wanted power saving less than a thirtieth of the normal operation energy consumption of air-conditioner than the fluorescent lamp of T8, air circulation reach nearly 300 cubic metres per hour.The user requires high to IAQ, or fits up back suggestion long period operation dedusting air vent mode, improves indoor air quality, and energy consumption is very low simultaneously.This pattern of employing, air-conditioner can be used as an air cleaner and use, no matter be can use in what season, increase hardly at air-conditioner on the basis of cost, have realized a kind of brand-new function more.

When the first embodiment employing pattern two, see Fig. 1, the drop front 16 that can open fits tightly with the housing 9 of indoor set, the first auxiliary air inlet 14 is in closure state, heat exchanger 6 work simultaneously, also promptly by the compressor in the off-premises station, outdoor heat exchanger, throttling arrangement (compressor, outdoor heat exchanger, throttling arrangement is a prior art, among the figure and not shown) and the refrigerating/heat pump system that forms of heat exchanger 6 moving, heat exchanger 6 is in any working condition in refrigerating/heating/dehumidifying, the function that air is had cooling/heating/dehumidifying, simultaneously, electrostatic precipitation layer 4 in the air cleaning unit powers up, be to have DC voltage between discharge electrode 4A and the dust collecting electrode 4B, the control of dust dust removing effects is arranged, indoor muddy air 10 is at air inlet 2, each filter course through air cleaning unit 20, promptly successively by filter course 3, electrostatic precipitation layer 4 and Combined Processing layer 5, pass through the hot wet process of heat exchanger 6 again through the pure air that fully filters, discharge from air outlet 8 by blower fan 7 pressurizations, become clean and treated comfort air 11.

Pattern two and pattern one are compared, its main difference is that the refrigerating/heat pump system in the pattern two is in running order, because the filtration, purification of air inlet has multilayer, its windage is bigger, but for the user, operation of air conditioner more is in the sub-load situation, such as, operation of air conditioner is after a period of time, and indoor temperature is basicly stable, and air-conditioning is in the sub-load situation, if employing frequency-changeable compressor, the rotating speed of compressor is not along with indoor temperature and design temperature difference are so not big, and adopts lower running frequency, and ventilation also there is no need to adopt excessive.For the occasion of certain curve motion of setting according to the user, air-conditioning/heat pump more also is to be in sub-load, and, for the requirement of sound often being adopted lower rotation speed of fan, at this moment, the resistance for air inlet does not have great requirement, suitable employing pattern two operations.And, when indoor temperature is suitable, but when needing dehumidifying, often adopt low wind speed for fear of blowing feeling, all can be better in the effect of low wind operating mode dedusting and dehumidifying.

Schematic diagram when Fig. 2 adopts pattern three operations for the first embodiment of the present invention, the main distinction of the indoor set of first embodiment among Fig. 2 and Fig. 1 is, see Fig. 2, drop front 16 lower ends are provided with rotating shaft 15, and an end is fixed on the drop front 16, and the guide pad 13 that can freely rotate and slide, rotating shaft 15 and guide pad 13 drive by driving mechanism 12, the top that makes drop front 16 is away from housing, opening of drop front 16 makes that having formed first between drop front 16 and the housing 9 assists air inlet 14, forms the opening of V-arrangement to front opening.The room air of introducing from the first auxiliary air inlet 14 19 mixes in housing with the muddy air 10 that enters through air cleaning device 20, carries out hot wet process through heat exchanger 6, is discharged from air outlet 8 by blower fan 7 pressurizations, becomes treated comfort air 11.Drop front 16 is to carry out closure or openness by driving mechanism 12, driving mechanism 12 includes the drive motors that is installed on the housing, gear train, tooth bar and chute guide rail etc., the driving drive disk assembly by driving mechanism 12 can make panel carry out closure or openness with the V-arrangement opening automatically.When drop front 16 is opened, can see that the positive side of fixed frame 37 is provided with gauge tap 35, when needs take out air cleaning unit 20, need press earlier gauge tap 35 with its outage after, do the operation of taking-up again.

Because the user is in using air-conditioning process, often there is the situation that needs indoor temperature to descend as early as possible, higher as indoor temperature, just begun to start the situation of air-conditioning, at this time the user can feel awfully hot, wish to reduce surrounding air and temperature on one's body at once, at this time, the user more pays close attention to the refrigerating capacity of air-conditioning and the air output of air-conditioning, require nature just so high to air quality, so have part not participate in the air handling process, close refrigerating capacity and improve air output through filtered air.The employing of the first auxiliary air inlet 14 has been avoided can't satisfying the demand of user's refrigerating capacity only adopting air inlet 2 air intakes and air inlet to have the pattern two of multiple filtration will influence air output.

During employing pattern three, muddy air 10 can enter the air-conditioner inner chamber from air inlet 2, also can enter the indoor machine of air-conditioner inner chamber simultaneously from the first auxiliary air inlet 14, be equivalent to increase the area of air flow channel, so both improve the outward appearance of air-conditioning and increased intake, and under off-mode, can reduce materials such as dust and enter air-conditioning inside, thereby guarantee the performance of air-conditioner.See Figure 14, for 1.5 wall-hanging air conditioners is example, be under the cooling condition situation, when adopting operational mode two and operational mode three, both a plurality of key parameters have bigger difference, as air output, when employing pattern three, when auxiliary air inlet was opened, air circulation per hour per hour rose to 630 cubic metres from 500 cubic metres, and air quantity has risen 26%; Simultaneously refrigerating capacity rises to 3700 watts from 3480 watts, and the Energy Efficiency Ratio of refrigeration also is significantly increased, and is elevated to 3.35 from 3.15.The raising of operational energy efficiency has special meaning for the market access of product, and the requirement of efficiency is generally all arranged on market, various countries, and the employing of the first auxiliary air inlet 14 can enlarge the market scope of product adaptation.

In the present embodiment, filter course adopts rustless metal net filtration layer, the very thin tungsten filament of the positive discharge of electrostatic precipitation layer, the negative pole control of dust is aluminium flake very, and the Combined Processing layer adopts individual layer active carbon adsorption layer, and overall windage is smaller, if the user has higher requirement to air cleaning, as adopt the MULTILAYER COMPOSITE processing layer, and then windage can continue to increase, and auxiliary air inlet is more remarkable to the lifting meeting of heat pump performance.Operational mode that present embodiment is above-mentioned and characteristics go for following various embodiments.
