Be located at the off-premises station control part 15 and the indoor set control part 16 of outdoor unit 2 and indoor units 3, possess not shown microcomputer respectively, each does the control operation according to contents of program of pre-installing in the microcomputer or the preceding content of setting of operation, now is described as follows.
That is,, carry out the basic controlling of operation with off-premises station control part 15 and indoor set control part 16 according to the table of each operating state of expression among the program of Fig. 6 and Fig. 9.At first the 1st step S1 is the lid 18b that opens remote controller 18 body 18a parts in the coverage diagram 5 (a), display part 18c content displayed such as liquid crystal are seen on the limit, the temperature key 58 of refrigerating operaton, heating operation switch key 56, dehumidifying key 57 and design temperature etc. is selected in the limit operation, select the operational mode of requirement, this is same with well-known air conditioner.
And, whenever press Menu key 59, then such shown in Fig. 5 (b), operational mode circulation described later is switched.Here the operational mode of She Dinging is to make the inner dry drying operation of indoor units and purify the self-purging operational mode of moving combination, or only make the inner dry dry operational mode of indoor units, so seeing display part 18c content displayed limit, the limit from the pattern of these 3 operations, implements the selection of required mode.When these patterns are switched, display part 18c show fixed time, for example show 10 seconds, then the user confirms selected operational mode easily.
The implementation operation beginning of operating air conditioner machine 1, the operation key 60 that stops to make power switch 13 closed action, and then power supply inserts and brings into operation.In addition, when refrigerating operaton, during heating operation, make the occasion of anion generator 53 work, with air cleaning key 61 by at ON.
Then in the 2nd step S2, judge and set which kind of operational mode.If refrigeration mode, the refrigerating operaton control that then enters the 3rd step S3; If heating mode, the heating operation control that then enters the 4th step S4; If dehumidification mode then enters the 5th step S5 dehumidifying operation control.Various controls and well-known air conditioner are same, carry out according to Fig. 9 tabulation.Then enter the 6th step S6, judge whether end of run.The 6th step is carried out repeatedly and is confirmed end of run.Confirm that at the 6th step S6 end of run then enters the 7th step S7.
At the 7th step S7: whether the operational mode before judging is refrigerating operaton pattern or dehumidification operating mode.Being judged as when not being refrigerating operaton pattern and dehumidification operating mode, then enter the 8th step S8, handle according to Fig. 9 tabulation carrying out end of run.In the 7th step S7, when judgement is refrigerating operaton pattern or dehumidification operating mode, then enter the 9th step S9.
In the 9th step S9, the refrigerating operaton of setting when judgement begins prior to operation, the postrun operational mode setting of dehumidifying are any situations in self-purging operational mode, dry operational mode, the non-selected pattern, judged result is when purifying operational mode, then in the 10th step S10, carry out making the inner dry drying of indoor units move processing, carry out purifying the operation processing again at the 11st step S11.When described judged result is dry operational mode, then enter the 12nd step S12, carry out that the inner dry drying operation of indoor units is handled.After implementation, then enter the 8th step S8 and carry out end process.Described judged result is the occasion of non-selected pattern, then enters the 8th step S8 and carries out the end of run processing.
Because carry out above several basic controlling, so air conditioner 1 is except can carrying out common refrigerating operaton, heating operation, dehumidifying operation, by selecting, set operational mode in advance, after refrigerating operaton or dehumidifying operation, can carry out the drying operation processing, the purification operation that make the indoor units inner drying as described below and handle.Do not implement the processing of such operational mode, promptly non-selected drying operation processing and the purification operation processing that makes the inner drying of indoor units.If select like this, then no matter operation is stopped, all can tackling and worry that air conditioner continues operation, handle thereby can make inner these the dry dry operations of indoor units handle, purify operation.
After refrigerating operaton or dehumidifying operation, the inner dry drying operation of indoor units is handled according to program and each operating state table control of Fig. 9 of Fig. 7.At first in the 1st step T1, each one is set in the duty dry in service that makes the inner drying of indoor units shown in Figure 9, be about to compressor 4 and set the state that refrigerating capacity is reduced, outdoor machine fan 9 is set in the continuous running status of low speed, or low speed and the running status that stops to replace mutually, indoor fan 10 is set in the utmost point low cruise state also lower than when operation dehumidifying, indoor set choke valve 14 is set in the valve state that closes, off-premises station expansion valve 7 states of being set in out, cross valve 5 is set in the refrigerating operaton position.
The last inlet scoop louvre window 42 of indoor units 3 places closed condition, and front panel 23 places out state, the position Yb that front air outlet louvre window 44b places level to go up slightly, and back air outlet louvre window 44a places closed position Xa.And, air door 36 places closed condition, front openings 24 when front panel 23 is out state is as the room air in the inlet scoop inspiration indoor units 3, in main channel stream 30, flow, behind heat exchanger indoor unit 8, indoor fan 10, slightly go up direction from air-out 26 to level and blow out, nearby flow at indoor set 3, and very fast being inhaled into again in the indoor units 3.About precipitator 49 be, can place the ON state, discharge electrode 50a is applied the 1st high voltage V
H1,, also can make its operation OFF as ozone generator 52 operations.Anion generator 53 also can place the ON state, also can place the OFF state.
Then be the 2nd step T2, measure the humidity Ha of the room air in the main channel stream 30 that flows into heat exchange department 8b upstream, front side with humidity sensor 21.Then be the 3rd step T3, judge the degree of humidity Ha.If humidity Ha is more than 70%, then enter the 4th step T4, not shown timer was set in 10 minutes.If humidity Ha is lower than 70%, but, then enter the 5th step T5, timer was set in 8 minutes,, then enter the 6th step T6, timer was set in 5 minutes if humidity Ha is lower than 40% more than 40%.
Enter the 7th step T7 afterwards, continue to make the inner dry drying operation of indoor units in the setting corresponding time of humidity Ha, be the 8th step T8 then, judge whether time through the timer setting, when reaching setting-up time, just enter the 9th step T9, finish to make the inner dry drying operation of indoor units.Afterwards,, be transferred to the control content of the purified treatment of the 11st step S11 in the primary control program (PCP) of Fig. 6, or be transferred to the control content that the end of run of the 8th step S8 is handled according to predefined content.
The inner dry drying operation of indoor units that makes is like this handled, and is that a kind of dehumidifying operation is handled.Through refrigerating operaton or dehumidifying operation, the a large amount of dew of indoor units 3 inner generations, major part is discharged to outdoor through not shown scupper hose, a part before refrigerating operaton or dehumidifying remain in behind the end of run, drip receiving plate 32 and after drip in receiving plate 34, or be attached on the heat exchanger indoor unit 8 etc.Behind refrigerating operaton or dehumidifying end of run, the temperature in the indoor units 3 evaporates the dew that remains in the indoor units 3 because of the room air that enters rises quickly.Thereby like this, the humidity in the indoor units 3 is near 100%, and by inner dry described dry processing of indoor units dehumidified, can prevent that indoor units 3 inside from becoming the perfect environment of microbial bacterial breeding.
Implementation makes inner dry described dry processing of indoor units, so that personnel do not contact the high temperature malaria in the chamber, just different with common dehumidifying operation shown in Figure 9, compressor 4 is controlled at the slow-speed of revolution, refrigerating efficiency is descended, and close and to close inlet scoop louvre window 42, then make room air as far as possible by rear side heat exchange department 8a as evaporator operation.And indoor fan 10 places than the low utmost point slow-speed of revolution of dehumidifying operation, reduces its air output as far as possible.And close back air outlet louvre window 44a, only open front air outlet louvre window 44b, and towards level slightly upward to, the air that then blows out is not delivered to the residential area in the room R, is back to the operation in the indoor units 3 once more, becomes so-called short circuit operation.
Make outdoor fan 9 keep continuous running status of low speed or low speed and stop the alternately state of switching, the temperature of rising front side heat exchange department 8b makes the water evaporates of condensation on its fin etc., attached water.And the flow air temperature in indoor units 3 that raises, quicken indoor units 3 internal condensation evaporations of water.In addition, rising indoor fan 10, air outlet 26 and in various louvre window 44a, the 44b of its near side (ns), 46 etc. temperature prevent dewfall.The result is that the moisture content of condensation evaporates rapidly in the indoor units, owing to be short circuit operation, then as evaporator operation, thereby at the rear side heat exchange department 8a that becomes low temperature the dewfall condensed water takes place, and is recovered as dripping.
Promptly, in refrigerating operaton, because indoor set choke valve 14 is open modes, rear side heat exchange department 8a, front side heat exchange department 8b are as evaporator operation, thereby moisture is becoming two heat exchange department 8a of low temperature, the fin surface dewfall of 8b in the room air, if it is many that dew becomes, then flow to the below, wander each receiving plate 32,34 that drips below two heat exchange department 8a, 8b, be discharged to outdoor along fin surface.
, when refrigerating operaton finishes, the residual condensed water to a certain degree of two heat exchange department 8a, 8b.Here, employing makes the inner dry drying operation of indoor units, and indoor set choke valve 14 places closed condition, and rear side heat exchange department 8a is as evaporator operation, front side heat exchange department 8b is as condenser working, thereby attached to the condensate evaporation of front side heat exchange department 8b, moisture evaporated is in rear side heat exchange department 8a condensation once more, because the air of rear side heat exchange department 8a suction area is little, the condensed water quantitative change of its per unit area is many, and the receiving plate that drips after successfully falling is discharged to outdoor.Consequently, when making the dry end of run of the inner drying of indoor units, the moisture in the indoor units being reduced, at least only is the water yield of adhering to of front side heat exchange department 8b condensation.And when making the inner dry drying operation of indoor units, the indoor fan low-speed running is low during than the dehumidifying operation, so, the minimizing effect of indoor units 3 internal water components height during than the dehumidifying operation.
In this dry running time that makes the inner drying of indoor units, Ying Yuqi when beginning operation, when refrigerating operaton finishes or during the dehumidifying end of run in the room R humidity Ha (temperature of humidity sensor measuring) direct proportion change, for example, under the high state of described humidity Ha, setting operation 10 minutes, is under the intermediateness at temperature Ha, then sets operation 8 minutes, under the low state of temperature Ha, set operation 5 minutes.These setting-up times also can be according to the variations such as efficient of air conditioner 1.Owing to be that 3 inner dry dry running times of indoor units and humidity Ha direct proportion ground change, so in the more occasion of indoor units 3 inner quantity of residual, implement to make for a long time the drying operation of the inner drying of indoor units, therefore will implement the suitable inner dry drying of indoor units that makes and move according to state.
Make the dry in service of indoor units inner drying this, precipitator 49 and anion generator 53 both can be ON, also can be OFF, if passable, and ON preferably.If ON, the anion that produces of the ozone that produces of precipitator 49 and anion generator 53 then, be mixed in the air that blows out and produce short-circuit flow, be drawn onto once more in the indoor units 3, then ozone of Hui Liuing and anion to a spot of microorganism of each, bacterium in the indoor units 3 also can sterilization, sterilization.
As previously discussed, the described drying operation that makes the indoor units inner drying is to make rear side heat exchange department 8a as evaporator operation, front side heat exchange department 8b is as condenser working, the ability that suppresses indoor fan 10, room air is not sucked indoor units 3 inside as far as possible, make the water evaporates of indoor units 3 internal condensations, utilize evaporimeter that it is reclaimed, and to outdoor drainage, thereby be a kind of operational mode that can reduce indoor units 3 interior humidities in the short time efficiently.And, make inner dry dry in service of indoor units this, deliver to air in the room R and be by air as the rear side heat exchange department 8a of evaporator operation, with the air mixing air that passes through as the front side heat exchange department 8b of condenser working, its humidity is lower, and the temperature appropriateness is even a part flows to the residential area, make hardly that personnel produce unplessantness displeasure in the chamber, the possibility that humidity Ha raises in the room R is also little.
(hereinafter referred to as the 1st dry operation Processing Example) handled in the described drying operation that makes the indoor units drying is to carry out short circuit operation, even air door 36 place's closed conditions, front air outlet louvre window 44b is transferred to the position Yb that level makes progress slightly, air in the indoor set 3 that air outlet 26 blows out blows once more from front openings 24 parts of the front panel 23 that is in out state and to pass back in the indoor units 3.Adopt short circuit operation, the moisture of indoor units 3 internal condensations is in the front side heat exchange department 8b evaporation as condenser working, in the rear side heat exchange department 8a dewfall as evaporator operation, forms discharge water and is discharged to outdoor.In contrast, below as with another embodiment (hereinafter referred to as the 2nd dry operation Processing Example) of Figure 10 explanation, air blows to outside the machine hardly in the indoor units 3, refluxes in indoor units 3, also can make the inner dry drying operation of indoor units.
That is, drying operation described the 2nd embodiment, that make the inner drying of indoor units is handled and is carried out according to program among Fig. 7 and each operating state table of Figure 10.At first be the 1st step T1, Jiang Gebu is set to the duty that the inner dry drying of indoor units is moved shown in Figure 10.Just the occasion with the 1st dry operation Processing Example that makes the inner drying of indoor units is different, front panel 23 is transferred to closed condition, front air outlet louvre window 44b is transferred to closed position Xb, and air door 36 is transferred to out state, and last inlet scoop louvre window 42 is transferred to closed condition or is opened state.Other each ones then occasion with the 1st dry operation Processing Example that makes the inner drying of indoor units are identical, compressor 4 places the continuous running status of low speed, outdoor machine fan 9 places the continuous running status of low speed, or the running status alternately switched of low speed and stopping, indoor fan 10 places utmost point low cruise state, and indoor set choke valve 14 places closed condition, and off-premises station expansion valve place opens state, cross valve 5 places the position of refrigeration, and back air outlet louvre window 44a is arranged on closed position Xa.
Adopt such setting, air in the indoor units 3 flows in main through-flow road 30, flow through heat exchanger indoor unit 8, indoor fan 10, by open communication 35, be back to main through-flow road 30 and heat exchanger indoor unit 8 again through communication paths 38 from air outlet 26 parts.Precipitator 49 also can be arranged on the ON state, and as ozone generator 52 operations, anion generator 53 also can be arranged on the ON state, also can make the OFF state.Each step T3～T9 after following the 2nd step T2 carries out equally with making inner the 1st dry dry occasion of moving Processing Example of indoor units, makes the inner dry drying operation of indoor units processing with end.
By making this structure, inner the 1st dry dry operation Processing Example of indoor units is different with making, be to become the operation that in indoor units 3, forms the circulation road, that is: the air in indoor units 3, utilization be transferred to utmost point low-speed running indoor fan 10 and from the heat exchanger indoor unit 8 main through-flow road 30 of flowing through, by left and right sides louvre window 46, flow through the back air outlet louvre window 44a that is in closed condition again, air outlet 126 parts of front air outlet louvre window 44b, and air door 36 is in the open communication 35 of open mode, the communication paths 38 that forms through front panel 23 back sides of closed condition and be back to the upstream side of heat exchanger indoor unit 8 once more.
Utilization forms the operation of circulation stream in indoor units 3, indoor set choke valve 14 places closed condition (throttling is arranged), from as condenser working, thereby the front side heat exchange department 8b that reaches a high temperature, air suction area is big flows out the high air of temperature, indoor units 3 inner moisture evaporated during with outflow refrigeration, dehumidifying end of run, air themperature in the indoor units 3 is raise, quicken condensate evaporation in the indoor units 3, also raise various louvre window 44a, the 44b of indoor fan 10, air outlet 26 and air outlet 26 near side (ns)s, 46 etc. temperature prevent dewfall.Consequently, the moisture of condensation evaporates rapidly in the indoor units 3, moisture evaporated flows in the circulation stream, thereby suck the little rear side heat exchange department 8a condensation of area at the air that reaches low temperature afterwards, successfully form discharge water and collect, discharge by the receiving plate 34 that drips as evaporator operation.
Therefore, effect and the 1st dry operation Processing Example that inner the 2nd dry dry operation Processing Example of indoor units is obtained are same, and, because front panel 23 places closed condition, minimizing is from the inspiratory capacity of room R, be that indoor units 3 interior air reflux in inner loop, with rear side heat exchange department 8a as evaporator operation, carry out dehumidification treatments, thereby the condensed waters such as dew of indoor units 3 inside are increased draining, can carry out efficient higher make the inner dry drying operation of indoor units.And, all place closed position Xa, Xb to move owing to be arranged on back air outlet louvre window 44a, the front air outlet louvre window 44b of air outlet 26, almost there is not air to blow in the room R.In addition, be transferred to closed condition though preferably will go up inlet scoop louvre window 42, inlet scoop 25 is closed, even there is not the structure etc. of switching mechanism, the state that air draught 25 is being opened wide also can obtain making the effect of the inner dry drying operation of indoor units.Left and right sides louvre window 46 relies on end user's operation, but from the front, if make left and right sides louvre window 46 deflection lefts, the air circulation in the indoor units 3 also can be carried out on the whole smoothly.
As operational mode, when refrigerating operaton or dehumidifying operation back setting self-purging operational mode, the operational mode control that the purification operation of carrying out after the inner dry drying operation of indoor units is handled is handled is to carry out according to each operating state table among Fig. 8 program list and Fig. 9.At first the 1st step U1 is that Jiang Gebu is set in the operating state that the inner dry drying of unit is moved shown in Figure 9, promptly, compressor 4 and outdoor machine fan 9 place halted state, indoor fan 10 places the low utmost point low cruise state of rotating ratio dehumidifying operation, off-premises station expansion valve 7 and indoor set choke valve 14 place the state of opening, and cross valve 5 places the position of refrigeration.
And, the last inlet scoop louvre window 42 of indoor units 3 is placed closed condition, front panel 23 also in off position, back air outlet louvre window 44a and front air outlet louvre window 44b place closed position Xa, Xb.Left and right sides louvre window 40 is rotated, and from front openings 24 sides, its fore-end forwards the left side to, so that the air-flow deflection left that indoor fan 10 produces.The state that valve 36 places out by the open communication 35 that can circulate, makes near the air outlet 26 through-flow roads 30 of master form with the rear side of front panel 22 and is communicated with stream 38 connections.
Like this, form the circulation stream in the indoor units 3, promptly from being positioned at indoor fan 10 process anion generators 53 next doors of leading through-flow road 30, flow to communication paths opening 35, flow through communication paths 38 again, flow through on the through-flow road 30 of master of heat exchanger indoor unit 8 upstream portion that precipitator 49 (ozone generator 52) is set, just be back to the circulation stream of indoor fan 10.In the indoor units, utilize indoor fan 10 to produce the backflow of the utmost point velocity air shown in the hollow dotted arrows among Fig. 3, promptly from indoor fan 10, in main through-flow road 30, flow to air outlet 26, flow to open communication 35, for another example shown in the hollow solid arrow like that, flow during being communicated with stream 38 from open communication 35, the precipitator 49 of flowing through (ozone generator 52), heat exchanger indoor unit 8, flow to indoor fan 10.In addition, precipitator 49 places the ON state, and discharge electrode 50a is applied the 1st high voltage V
H1, as ozone generator 52 actions, anion generator 53 also places the ON state.
Then be the 2nd step U2, not shown timer was set in 10 minutes.Enter the 3rd step U3 afterwards.This step starts timer, begins to purify operation.Enter the 4th step U4 afterwards, judge whether the stipulated time through setting in the timer, promptly whether through 10 minutes, judge the time (10 minutes) that has reached setting, then enter the 5th step U5, finish to purify operation in this step, Jiang Gebu is controlled at halted state shown in Figure 9.
Described purification operation is handled when reducing refrigerating operaton and the microorganism, the bacterium that are attached to each one in the indoor units 3 during heating operation implemented.This purification operation is handled and is, is stopping kind of refrigeration cycle, and indoor fan 10 rotating speeds place the state of utmost point low speed, and air is refluxed in indoor units 3.That is, close air outlet 26, and the inlet scoop of front openings 24 and last inlet scoop 25, remain on air-tight state in the indoor units as far as possible.Open throttling 33, make left and right sides louvre window 46 deflection lefts, thereby in indoor units, form the utmost point velocity air stream of the oval circulation of diagonal.Adopt like this and reflux, the discharge electrode 50a of precipitator 49 applies the 1st high voltage V
H1, make it as ozone generator 52 work, the ozone of its generation, and anion generator 53 places the anion that the ON state takes place can be full of indoor units inside.
Consequently, microorganism, bacterium sterilization effectively, the sterilization that each one in the indoor units 3 is adhered to.And ozone and anion exist simultaneously, more effectively reduce microorganism, bacterium than individualism is a kind of.And during this purification operation was handled, the front openings 24 of air outlet 26, inlet scoop, last inlet scoop 25 were closed conditions, and ozone does not leak in the room R, does not have the stink of ozone in the room R.In order to prevent that ozone from leaking in the room R, the concentration that improves the inner ozone of indoor units is effective.
The precipitator of use in refrigeration system in the past depends on refrigeration, the heating efficiency of air conditioner, and volume is bigger.By comparison, the volume of the precipitator that uses of air conditioner of the present invention is one medium-sized approximately.This volume also is half of heat exchanger indoor unit approximately, thereby precipitator can be biased in any one side about heat exchanger indoor unit.State is being set like this, the ozone concentration that takes place when promptly precipitator is worked as ozone generator, higher in the nearby scope of precipitator is set, and other zones are, this is improper.In the present embodiment, when especially purifying the operation processing, form communication paths 38 in the indoor units 3 air is refluxed, the ozone integral body of generation is distributed equably.Thereby, with not relying on connection stream 38 example in the past of air circulation is compared, can in the extremely short time, ozone be distributed to other zones equably, make indoor units 3 interior ozone concentrations reach even distribution in the short time.
Among the described embodiment, precipitator 49 also can be as ozone generator 52 performance functions, but ozone generator 52 also can be provided with separately, and is independent separately with precipitator 49.The drying operation of indoor units inner drying is handled, when purifying operation and handling, is used inlet scoop louvre window 42 and will go up inlet scoop 25 and close, and do not load onto inlet scoop louvre window 42, to go up the state that is opening wide inlet scoop 25 also passable.This occasion though effect reduces, can obtain drying effect in enough indoor units 3 and microorganism, the sterilization of bacterium, sterilization effect.
That is understood as described is such, if adopt the present invention, can worry many humid air blows to indoor, reduce personnel's comfort in the chamber, after refrigerating operaton stops, but solve the interior many wet conditions of high temperature of indoor units in the short time, reduce microorganism, bacterial reproduction, thereby prevent the stench that microorganism, bacterial reproduction produce, can obtain to carry out on the health effect of good air-conditioning etc.
