The operation of the package AC plant of the present utility model with said structure is described below.What should remind is to move the operation of describing package AC plant by the standard of refrigerating mode.
Fig. 9 and 10 is vertical cross-sectional schematic of the utility model package AC plant.What should remind is for describing the operation of air-conditioner, only to show some critical pieces among these figure, and all parts are not shown.
Specifically, shown in Fig. 9 is ruuning situation when not carrying out air-cleaning function, and shown in Figure 10 is ruuning situation when carrying out air-cleaning function.
If the air-conditioner operation, then left and right sides fan electromotor 450 work are rotated left indoor fan 420 and right ventricle's internal fan 420.Make working fluid flow through heat exchange loop when in addition, compressor (referring to the Reference numeral 560 of Fig. 4) moves.Specifically, what meet the requirements is that indoor fan 420 adopts centrifugal fan, so that effectively utilize the interior space, and outdoor fan 460 adopts tube-axial fan, so that increase air quantity.
The rotation that is separately positioned on the indoor fan 420 of left and right sides makes room air suck through preceding air-breathing part 210, and makes air pass through indoor heat converter 400.The lower air of temperature through indoor heat converter 400 heat exchanges is sucked into indoor fan 420, discharges along the circumferencial direction of indoor fan.For this reason, indoor fan 420 can be used centrifugal fan, and specifically, indoor fan 420 can be a turbine fan, thereby can increase air quantity.
The air of discharging along the peripheral direction of indoor fan 420 flows along air guide member 300.In addition, be the direction of guiding discharged air, can distinguish the number of times of carrying out air-cleaning function and not carrying out air-cleaning function.
Ruuning situation under the situation of not carrying out air-cleaning function is at first described.
Under the situation of air being discharged forward by discharge-channel, stepper motor rotates, and makes the rear end of path guide plate 354 up, and the bottom surface of filter mounting portion 360 is closed in the front of Open from This Side discharge-channel 352.
Therefore, as shown in Figure 9, do not flow into high quality of filter 370 by indoor fan 420 force ventilated air, but all be discharged to the front through discharge-channel 352 by discharge unit 220.At this moment, must make exhaust valve 230 descending, open discharge unit 220 with this.Solid arrow is represented the running status of exhaust valve 230 and path guide plate 354.Air-flow when in addition, hollow arrow is represented not carry out air-cleaning function.
Ruuning situation under the situation of carrying out air-cleaning function is described below.
In order to purify the air that is discharged in the conditioned space, the driving of stepper motor 356 makes the rear end of path guide plate 354 descending.As shown in figure 10, block discharge-channel 352 thus, forced the lower surface of the air inflow filter mounting portion 360 that blows out by indoor fan 420.
The air that enters the inner space of filter mounting portion 360 from the bottom is purified after by high quality of filter 370, and the air that purified is discharged into the top by filter grid 740.Certainly, because air is not discharged to the front by discharge-channel 352, thus require exhaust valve 230 to be up to the top this moment, so that block discharge unit 220.
If above-mentioned discharged air is by high quality of filter 370, then airborne impurity obtains filtering, and is indoor thereby the air that will more clean offers.Therefore, owing to offer the air process purified treatment and the cooling processing of conditioned space, so more comfortable environment can be provided.
The driving of outdoor fan 460 is sucked in the air-conditioner outdoor air.In other words, the rotation of outdoor fan 460 makes extraneous air pass through the side draught pore 720 and the last suction hole 730 inflow air-conditioners of casing 700.The air that enters air-conditioner flows along hood 500, to be drawn onto in the outdoor fan 460.In addition, the air that is discharged into the back through outdoor fan 460 carries out heat exchange with the working fluid of heat exchange circulation in by outdoor heat converter 550.At this moment, the Hot air quilt of working fluid passes to and need be discharged in the outdoor exhaust.
At this moment, the air with lower temperature that is introduced into air-conditioner inside under room temperature state flows through the neighboring of compressor 560, and the temperature of compressor 560 is reduced.
By a separate bracket (not shown) fan electromotor 450 is connected on the rear surface of bottom air guide member.Certainly, the method that provided is provided connected mode.In other words, also fan electromotor 450 can be directly connected on the air guide member.Specifically, just the driving shaft of fan electromotor is not inserted in the air guide member of bottom, but is inserted into the integral body of fan electromotor 450 in the air guide member of bottom and installs.
In addition, a picture frame can be contained in the front surface of header board 200, improve the outward appearance of package AC plant with this.Moreover, can form a display panel at the idle position of the front surface of header board 200, for example LCD monitor or PDP plate are as electronic image, monitor or television.
In addition, compressor is contained in the middle part of the utility model package AC plant, so that move.Although be provided with two outdoor fans 460, that is to say a pair of outdoor fan, compressor not necessarily will be arranged between them.In other words, although compressor is set at the either side of outdoor member, as long as, improve heat exchanger effectiveness and just be out of question to spreading all over all area air-supplies of heat exchanger.
In package AC plant of the present utility model, owing to comprehensive be inhaled into of room air from the indoor unit part, so can expect, the whole efficiency of air-conditioner can improve.
In addition, because the front at header board forms grid unlike prior art, so can't see internal part from the outside.In addition, when air-conditioner did not move, because exhaust valve has blocked the indoor exhaust hole, institute was so that the positive appearance of air-conditioner is more attractive in appearance.
Moreover because the header board front side is the curved raised structures in middle part, so appearance is more attractive in appearance.To make the consumer interested so can expect this.
In addition because do not form traditional grid, so header board can be owing to contaminant particles, for example be deposited in the suction hole of grid or the dust on the steam vent and polluted, and be convenient to header board is cleaned.In other words, when not using air-conditioner or during with air cleaning,, passing through steam vent so can prevent contaminant particles, thereby avoided the pollution of header board substantially because exhaust valve has blocked the indoor exhaust hole.
It will be apparent to those skilled in the art that, can make various improvement and conversion the utility model.Therefore, the utility model has covered improvement and the conversion that the utility model is made in the scope of the equivalent that falls into appending claims and they.
