, control device 80, in order to manage the action of air conditioner 10, only uses target temperature not enough.That is, after reaching target temperature, switch action, but will substantially exceed target temperature according to the characteristic of indoor variations in temperature, or be significantly less than on the contrary target temperature.Therefore,, in order to control the action of the compressor 51 of air conditioner 10, according to target temperature, set the 1st threshold temperature and the 2nd threshold temperature.The 1st threshold temperature is being used under heating mode conventionally, and the 2nd threshold temperature is configured to higher than the 1st threshold temperature, is using fast under heating mode.
About common heating mode and the switching of heating mode fast, according to the flow chart of Fig. 8, describe.Conventionally heating mode and quick heating mode are the patterns of selecting in heating running, thereby control device 80 carries out the confirmation (step S1) of operating condition when the starting that heats running according to the control information of air conditioner 10.
Functioning example beyond heating running, as in cooling operation etc., can not be selected quick heating mode, thereby omit the non-explanation that heats the situation of running.In judgement, be to heat after running, then control device 80 is prepared for judging common heating mode or the information of quick heating mode.Control device 80 is obtained and the relevant information of starting, and such as whether storing in the memory in Indoor Control Device 82, represents that user's 84 grades that use a teleswitch have selected the information (step S3) of quick heating mode.
In the starting that heats running under quick heating mode, judge whether the indoor temperature being determined by indoor temperature transmitter 26 has reached the 2nd threshold temperature (target temperature) (step S7).If reach the 2nd threshold temperature, reached target, thereby finished quick heating mode, control device 80 makes timer starting (step S8).The in the situation that of miss the mark temperature, continue to monitor whether reached target temperature (step S7).
When after timer starting through during the scheduled time, in control device 80, determine to finish quick heating mode (step S9), make to enter common heating mode (step S10).Through heating mode (step S9) continuously and healthily before the scheduled time.
(4-3) action under quick heating mode
Below, the action of the air conditioner 10 under quick heating mode is described according to the sequential chart of Fig. 9.In the indoor temperature of Fig. 9 and the curve map of compressor operation frequency, solid line represents an example of the indoor temperature change generated in case under quick heating mode, and single-point line represents an example of the indoor temperature change generated in case under common heating mode.Moment tm0 in Fig. 9, judgement is quick heating mode (step S4), sets the 2nd threshold temperature (step S5), the starting under heating mode starts (step S6) fast.
At this moment tm0, the temperature T 0 being determined by indoor temperature transmitter 26 is significantly less than target temperature Tg.At moment tm0, meet to measure temperature T 0 lower than target temperature Tg(Tg>T0) condition, and meet the condition of quick heating mode, thereby control device 80 output command compressor electric motor portions 59 make operating frequency become maximum signal.From moment tm0, compressor electric motor portion 59 makes the operating frequency of compressor 51 become maximum.
In addition, control device 80 is owing to meeting above-mentioned two conditions, thereby output command indoor fan motor portion 23 is set as making the signal of the tap of air quantity maximum.According to this order, the tap corresponding to maximum (top) speed is selected in a plurality of taps corresponding with many grades of rotating speeds by indoor fan motor portion 23.Thus, indoor fan 22 is made as maximum by rotating speed and blows to indoor heat converter 21.Interval shown in oblique line in the curve map of the maximum quantity of wind of Fig. 9, indoor fan 22 is made as maximum by rotating speed and blows.In addition, when indoor fan 22 is made as rotating speed maximum and blows, horizontal blade 34 and vertical vane 32 move to the pressure loss making in air-supply and are minimum position and are fixed on this.Specifically, vertical vane 32 moves in Fig. 6 of two vertical vane 32a, 32b with the position shown in double dot dash line, the angle θ with respect to front and back is minimum position, the state in standard-sized sheet.In addition, horizontal blade 34 so that horizontal blade 34a, the 34b of the first half and the latter half all the mode in level move and fix.In the structure of this indoor set 20, horizontal blade 34 is in level, and the pressure loss in air-supply is minimum thus.
Then, at moment tm1, indoor temperature transmitter 26 is measured to and surpasses the 1st threshold temperature.But owing to being quick heating mode, thereby control device 80 do not reduce the operating frequency of compressor 51, and makes compressor 51 maintain transport maximum frequency.Equally, indoor fan 22 maintains maximum quantity of wind, and vertical vane 32 and horizontal blade 34 maintain the state that wind loss is minimum position that is fixed in.
At moment tm2, indoor temperature transmitter 26 is measured to over target temperature (the 2nd threshold temperature).This result detected, control device 80 reduces the operating frequency of compressor 51.But control device 80 is configured to and makes to reduce by stages according to per scheduled time, to the operating frequency of compressor 51 can sharply not reduced.Therefore,, at this moment tm2, control device 80 reduces by 1 grade by the operating frequency of compressor 51.But after moment tm2, the operating frequency that makes compressor 51 is 0, do not stop the control of compressor 51.If mean stopping of compressor 51 in the situation that moment tm2 makes the operating frequency of compressor 51 reduce by 1 grade, the reduction of the operating frequency of compressor 51 is limited.Such as not making like this control that compressor 51 stops continue to carry out in during quick heating mode.
In addition, from moment tm2, control device 80 starts to change the wind direction of vertical vane 32 and horizontal blade 34.By the end of being all now by vertical vane 32 and horizontal blade 34 is fixing comes to indoor air-supply, thereby likely there is bias in indoor Temperature Distribution, but indoor temperature transmitter 26 is measured target temperature Tg.Therefore, control device 80 makes vertical vane 32 and horizontal blade 34 alternately move from moment tm2, for example, according to the order change wind direction of bottom right, lower-left, upper left, upper right.Now, vertical vane 32 and horizontal blade 34 is back and forth in up and down between maximum inclination separately.
Then, in moment tm2, control device 80 makes timer starting.
During from moment tm2 to moment tm3, indoor temperature overshoot (overshoot), and rise over target temperature Tg.Therefore, control device 80 is when through the scheduled time, and the measured value that is judged to be indoor temperature transmitter 26 surpasses target temperature Tg, and the operating frequency of compressor 51 is sequentially reduced.But, can not make the operating frequency of compressor 51 lower than predetermined lower limit RL.
Then, at moment tm3, indoor temperature transmitter 26 is measured temperature controller closing temperature Toff.This temperature controller closing temperature Toff refers to the temperature that under common heating mode, compressor 51 is stopped.But, under quick heating mode, make the operating frequency of compressor 51 keep lower limit RL.Therefore, even if room temperature surpasses temperature controller closing temperature Toff, also a little rises, then head for target temperature T g slow decreasing.
At moment tm4, from timer, start starting through the scheduled time, control device 80 finishes quick heating mode.And after moment tm4, air conditioner 10 is turning round under heating mode conventionally.

On the other hand, as shown in figure 11, the display frame 28a being also provided with in the front of indoor set 20.In the display frame 28a shown in Figure 11, show and represent that the power-monitoring that enters quick heating mode shows that the demonstration 28c of 28b, design temperature, timer show 28d etc.
Want the user who air conditioner 10 is set as to quick heating mode to press for example starting button 84g of remote controller 84.After starting button 84g is pressed, from remote controller 84, to control device 80, send the indication that makes to be set as quick heating mode.From remote controller 84, receive the control device 80 of the indication of quick heating mode, in memory, storage is set to the information of quick heating mode.In this state, as shown in the moment tm0 of Fig. 9, in the mensuration temperature of indoor temperature transmitter 26, during lower than target temperature Tg, under heating mode, start (step S6) fast as shown in Figure 8.
When starting after starting under heating mode fast, at the display frame 84h of remote controller and the display frame 28a of indoor set 20, carry out demonstration shown in Figure 12 (a)～Figure 12 (h), that expression enters quick heating mode.The numerical value of the demonstration 28c of design temperature is design temperature, learns the on-state of timer by the mark of Displaying timer device demonstration 28d, and by showing change pattern in 28b at power-monitoring, it is quick heating mode that user can easily clearly learn.The demonstration of the display frame 84h of remote controller and the display frame 28a of indoor set 20 (changes shown in g, Figure 12 (h) according to Figure 12 (a), Figure 12 (b), Figure 12 (c), Figure 12 (d), Figure 12 (e), Figure 12 (f), Figure 12.
(4-5) starting of cooling operation
Starting for cooling operation in this air conditioner 10 is provided with two kinds of patterns.Be a common refrigeration mode, another kind is fast-refrigerating pattern.In this embodiment, the starting of so-called cooling operation refers to when indoor temperature miss the mark temperature and blows out cold air, makes indoor temperature reach the action of expecting state.
Wherein, in cooling operation, in order to control the action of the compressor 51 of air conditioner 10, according to target temperature, the 3rd threshold temperature and the 4th threshold temperature have been set.The 3rd threshold temperature is being used under refrigeration mode conventionally, and the 4th threshold temperature is configured to, lower than the 3rd threshold temperature, under fast-refrigerating pattern, use.
Switching about common refrigeration mode and fast-refrigerating pattern, describes according to the flow chart of Figure 13.Conventionally refrigeration mode and fast-refrigerating pattern are the patterns of selecting in cooling operation, thereby control device 80 carries out the confirmation (step S21) of operating condition when the starting of cooling operation according to the control information of air conditioner 10.
Functioning example beyond the cooling operation, as heated in running etc., can not be selected fast-refrigerating pattern, thereby omit the explanation of the situation of non-cooling operation.When judgement is cooling operation, then control device 80 is prepared for judging common refrigeration mode or the information of fast-refrigerating pattern.Control device 80 is obtained and the relevant information of starting, and such as whether storing in the memory in Indoor Control Device 82, represents that user's 84 grades that use a teleswitch have selected the information (step S23) of fast-refrigerating pattern.
In the starting of the cooling operation under fast-refrigerating pattern, whether the indoor temperature that judgement is determined by indoor temperature transmitter 26 has reached the 4th threshold temperature (target temperature) (step S27).If reach the 4th threshold temperature, reached target, thereby finished fast-refrigerating pattern, control device 80 makes timer starting (step S28).The in the situation that of miss the mark temperature, continue to monitor whether reached target temperature (step S27).
After timer starting, through during the scheduled time, in control device 80, determine to finish fast-refrigerating pattern (step S29), make to enter common refrigeration mode (step S30).Through refrigeration mode (step S29) continuously and healthily before the scheduled time.
(4-6) action under fast-refrigerating pattern
Below, according to the action of the air conditioner 10 under the sequential chart explanation fast-refrigerating pattern of Figure 14.In the indoor temperature of Figure 14 and the curve map of compressor operation frequency, solid line represents an example of the indoor temperature change generated in case under fast-refrigerating pattern, and single-point line represents an example of the indoor temperature change generated in case under common refrigeration mode.In the moment of Figure 14 tm10, judgement is fast-refrigerating pattern (step S24), sets the 4th threshold temperature (step S25), and the starting under fast-refrigerating pattern starts (step S26).
At this moment tm10, the temperature T 0 being determined by indoor temperature transmitter 26 substantially exceeds target temperature Tg.At moment tm10, meet to measure temperature T 0 higher than target temperature Tg(Tg<T0) condition, and meet the condition of fast-refrigerating pattern, thereby control device 80 output command compressor electric motor portions 59 make operating frequency become maximum signal.From moment tm10, compressor electric motor portion 59 makes the operating frequency of compressor 51 become maximum.
In addition, control device 80 is owing to meeting above-mentioned two conditions, thereby output command is set as indoor fan motor portion 23 and outdoor fan motor portion 58 to make the signal of the tap of air quantity maximum.According to this order, the tap corresponding to maximum (top) speed is selected in a plurality of taps corresponding with many grades of rotating speeds by indoor fan motor portion 23 and outdoor fan motor portion 58.Thus, indoor fan 22 is made as rotating speed maximum to indoor heat converter 21 air-supplies.Interval shown in oblique line in the curve map of the maximum quantity of wind of Figure 14, indoor fan 22 is made as maximum by rotating speed and blows.In addition, when indoor fan 22 is made as rotating speed maximum and blows, horizontal blade 34 and vertical vane 32 move to the pressure loss making in air-supply and are minimum position and are fixed on this.Specifically, vertical vane 32 moves in Fig. 6 of two vertical vane 32a, 32b with the position shown in double dot dash line, the angle θ with respect to front and back is minimum position, the state in standard-sized sheet.In addition, horizontal blade 34 so that horizontal blade 34a, the 34b of the first half and the latter half all the mode in level move and be fixed.In the structure of this indoor set 20, when cooling operation, horizontal blade 34 is also in level, and the pressure loss in air-supply is minimum thus.
Then, at moment tm11, indoor temperature transmitter 26 is measured to lower than the 3rd threshold temperature.But owing to being fast-refrigerating pattern, thereby control device 80 do not reduce the operating frequency of compressor 51, and makes compressor 51 maintain transport maximum frequency.Equally, indoor fan 22 and propeller fan 57 maintain maximum quantity of wind, and vertical vane 32 and horizontal blade 34 maintain the state that wind loss is minimum position that is fixed in.
At moment tm12, indoor temperature transmitter 26 is measured to lower than target temperature (the 4th threshold temperature).This result detected, control device 80 reduces the operating frequency of compressor 51.But control device 80 is configured to and makes to reduce by stages according to per scheduled time, to make compressor 51 can sharply not reduce operating frequency.Therefore,, at this moment tm12, control device 80 reduces by 1 grade by the operating frequency of compressor 51.But after moment tm12, the operating frequency that makes compressor 51 is 0, do not stop the control of compressor 51.If mean stopping of compressor 51 in the situation that moment tm12 makes the operating frequency of compressor 51 reduce by 1 grade, the reduction of the operating frequency of compressor 51 is limited.Such as not making the control that compressor 51 stops continue to carry out in during fast-refrigerating pattern like this.
In addition, from moment tm12, control device 80 starts to change the wind direction of vertical vane 32 and horizontal blade 34.By the end of now, be all that vertical vane 32 and horizontal blade 34 is fixing next to indoor air-supply, thereby likely there is bias, indoor temperature transmitter 26 mensuration target temperature Tg in indoor Temperature Distribution.Therefore, control device 80 makes vertical vane 32 and horizontal blade 34 alternately move from moment tm12, for example, according to the order change wind direction of bottom right, lower-left, upper left, upper right.Now, vertical vane 32 and horizontal blade 34 is back and forth in up and down between maximum inclination separately.
Then, in moment tm12, control device 80 makes timer starting (step S28).
During from moment tm12 to moment tm13, indoor temperature overshoot, and decline lower than target temperature Tg.Therefore, control device 80, when through the scheduled time, is judged to be the measured value of indoor temperature transmitter 26 lower than target temperature Tg, and the operating frequency of compressor 51 is sequentially reduced.But, can not make the operating frequency of compressor 51 lower than predetermined lower limit RL.
Then, at moment tm13, indoor temperature transmitter 26 is measured temperature controller closing temperature Toff.This temperature controller closing temperature Toff refers to the temperature that under common refrigeration mode, compressor 51 is stopped.But, under fast-refrigerating pattern, make the operating frequency of compressor 51 keep lower limit RL.Therefore, even if room temperature surpasses temperature controller closing temperature Toff, also a little declines, then head for target temperature T g rising.
At moment tm14, from timer, start starting through the scheduled time, control device 80 makes fast-refrigerating pattern finish (step S29).And at this moment tm14, indoor fan 22 and propeller fan 57 finish with the running of maximum quantity of wind, the stereomutation of vertical vane 32 and horizontal blade 34 also finishes.And, after moment tm14, air conditioner 10 turn round under common refrigeration mode (step S30).
(4-7) demonstration of fast-refrigerating pattern
The demonstration of fast-refrigerating pattern and quick heating mode are that the mode of fast-refrigerating pattern is carried out clearly to notify user in the same manner.The user who wants the air conditioner 10 to be set as fast-refrigerating pattern for example presses the starting button 84g of remote controller 84 under cooling operation pattern.Under cooling operation pattern, after starting button 84g is pressed, from remote controller 84, to control device 80, send the indication that makes to be set as fast-refrigerating pattern.From remote controller 84, receive the control device 80 of the indication of fast-refrigerating pattern, in memory, storage is set to the information of fast-refrigerating pattern.In this state, as shown in the moment tm10 of Figure 14, in the mensuration temperature of indoor temperature transmitter 26, during higher than target temperature Tg, under fast-refrigerating pattern, start as shown in figure 13 (step S26).
When start starting under fast-refrigerating pattern after, at the display frame 84h of remote controller 84 and the display frame 28a of indoor set 20, represent to enter the demonstration of fast-refrigerating pattern.For example, preferably carry out distinguishing at a glance the demonstration of turning round under which kind of pattern, as Figure 12 (a)～Figure 12 (h) if as shown in utilize the quick heating mode of red display, utilize the blue fast-refrigerating pattern etc. that shows.
(5) feature
(5-1), in the refrigerating circuit 14 of above-mentioned embodiment, heating when running, cold-producing medium is according to an example of compressor 51, indoor heat converter 21, the motor-driven valve 54(mechanism of decompressor), the order of outdoor heat converter 53 circulates.Under common heating mode (step S10), as shown in the single-point line in Fig. 9, when the temperature being determined by indoor temperature transmitter 26 (example of indoor temperature) reaches the 1st threshold temperature Th1, the operating frequency of compressor 51 starts to decline.Specifically, in an example of the 1st threshold temperature Th1 and target temperature Tg(the 2nd threshold temperature) between, for example with 0.5 ℃ of scale, set a plurality of C.Ts, when surpassing this C.T, by control device 80, the operating frequency of compressor 51 is declined.Therefore,, under the common heating mode representing with single-point line, reach target temperature Tg and become delay.
In the refrigerating circuit 14 of above-mentioned embodiment, when cooling operation, cold-producing medium is according to an example of compressor 51, outdoor heat converter 53, the motor-driven valve 54(mechanism of decompressor) and the order of indoor heat converter 21 circulate.Under common refrigeration mode (step S30), as shown in the single-point line in Figure 14, when the temperature being determined by indoor temperature transmitter 26 (example of indoor temperature) reaches the 3rd threshold temperature Th3, the operating frequency of compressor 51 starts to decline.Specifically, in an example of the 3rd threshold temperature Th3 and target temperature Tg(the 4th threshold temperature) between, for example with 0.5 ℃ of scale, set a plurality of C.Ts, when lower than this C.T, by control device 80, the operating frequency of compressor 51 is declined.Therefore,, under the common refrigeration mode representing with single-point line, reach target temperature Tg and become delay.
On the other hand, under any one pattern of quick heating mode and fast-refrigerating pattern, even indoor temperature transmitter 26 determines the 1st threshold temperature Th1 or the 3rd threshold temperature Th3, the operating frequency of compressor 51 does not decline yet, and maintains peak frequency.Like this, even the 1st threshold temperature Th1 declining from the operating frequency of compressor 51 under common heating mode to the temperature province of target temperature Tg or from the 3rd threshold temperature Th3 to the temperature province of target temperature Tg, if select quick heating mode or fast-refrigerating pattern, compressor 51 can turn round in the situation that not reducing operating frequency.Under quick heating mode, the operating frequency that prevents compressor 51 reduces during from the 1st threshold temperature Th1 to target temperature Tg, thereby can accelerate the temperature rising of indoor temperature.Under fast-refrigerating pattern, the operating frequency that prevents compressor 51 reduces during from the 3rd threshold temperature Th3 to target temperature Tg, thereby the temperature that can accelerate indoor temperature declines.Like this, by selecting quick heating mode, compare with common heating mode, can shorten the time that indoor temperature reaches design temperature, can improve comfortableness.Equally, by selecting fast-refrigerating pattern, compare with common refrigeration mode, can shorten the time that indoor temperature reaches design temperature, can improve comfortableness.
(5-2) known according to the block curve of the compressor operation frequency of Fig. 9, under quick heating mode, control device 80 makes the operating frequency of compressor 51 maintain peak frequency until reach an example of target temperature Tg(the 2nd threshold temperature).Like this, if select quick heating mode, at compressor 51 with peak frequency running until while reaching target temperature Tg, the running by compressor 51 before reaching target temperature Tg is provided to indoor heat and is maximized.That is, the area the solid line from moment tm1 to moment tm2 and single-point line is maximized as shown in Figure 9.Consequently, the time that reaches target temperature Tg is shortened.
Known according to the block curve of the compressor operation frequency of Figure 14, under fast-refrigerating pattern, control device 80 makes the operating frequency of compressor 51 maintain peak frequency until reach an example of target temperature Tg(the 4th threshold temperature).Like this, if select fast-refrigerating pattern, at compressor 51 with peak frequency running until while reaching target temperature Tg, be maximized from the indoor heat of taking away by the running of compressor 51 before reaching target temperature Tg.That is, the area the solid line from moment tm11 to moment tm12 and single-point line is maximized as shown in figure 14.Consequently, the time that reaches target temperature Tg is shortened.
(5-3) moment tm0 in the curve of the known maximum quantity of wind at Fig. 9 is to moment tm4, and indoor fan 22 reaches maximum (top) speed.That is,, under quick heating mode, control device 80 makes indoor fan maintain maximum (top) speed until reach an example of target temperature Tg(the 2nd threshold temperature).
Moment tm10 in the curve of the known maximum quantity of wind at Figure 14 is to moment tm14, and indoor fan 22 reaches maximum (top) speed.That is,, under fast-refrigerating pattern, control device 80 makes indoor fan 22 maintain maximum (top) speed until reach an example of target temperature Tg(the 4th threshold temperature).
Like this, due under quick heating mode or make indoor fan 22 maintain maximum (top) speed until reach target temperature Tg, thereby the air quantity of sending to indoor heat converter 21 can be increased to the maximum capacity of indoor fan 22 under fast-refrigerating pattern.Thus, the ability that realizes air conditioner 10 improves, and shortens the time that reaches target temperature Tg.
In addition, selecting under the situation of quick heating mode, compressor 51 is with peak frequency running until reach target temperature Tg, thereby compressor 51 is easily in superheat state.Like this, by making indoor fan 22 turn round to increase the air quantity that offers indoor heat converter 21 with maximum (top) speed before reaching target temperature Tg, cooled dose of more heat seizes, thereby when making indoor temperature fast rise, can suppress compressor 51 overheated and have problems.
(5-4) as shown in Figure 9,, during from moment tm0 to moment tm2, control device 80 is by an example of vertical vane 32 and horizontal blade 34(wind direction adjusting plate) be fixed on maximum quantity of wind position.Specifically, it is minimum position that vertical vane 32 is fixed in angle θ, and horizontal blade 34 is fixed to level.These vertical vanes 32 and horizontal blade 34 towards with air-supply in the pressure loss be minimum towards consistent.Now, although indoor fan 22 is turning round with maximum (top) speed, the pressure loss of vertical vane 32 and horizontal blade 34 is minimum, thereby can carry out heat exchange with maximum quantity of wind.Therefore, easily to indoor, heat fast, and reaching target temperature Tg with the compressor 51 of transport maximum frequency run under quick heating mode before, be not easy overheated.
Equally, as shown in figure 14, during from moment tm10 to moment tm12, control device 80 is by an example of vertical vane 32 and horizontal blade 34(wind direction adjusting plate) be fixed on maximum quantity of wind position, easily fast to the cold row of indoor system.
(5-5) shown in Fig. 9 from moment tm2 to moment tm4 during although to belong to be quick heating mode, reached target temperature Tg(the 2nd threshold temperature) after during.Wind direction is fixed during from moment tm0 to moment tm2, to do not provide as far as possible many heats to indoor in the situation that not adding as far as possible thermocompressor 51.Therefore, in the indoor bias that often easily produces temperature.Therefore, during from moment tm2 to moment tm4, make vertical vane 32 and horizontal blade 34 alternately change up and down the action of the action of wind direction and left and right change wind direction.In this embodiment, successively according to the order change wind direction of bottom right, lower-left, upper left, bottom right.At this, importantly three-dimensionally change wind direction with left and right directions along the vertical direction, be not limited to above-mentioned order.By making vertical vane 32 and horizontal blade 34 alternately change up and down the action of wind direction and the action of left and right change wind direction, air is stirred, the bias of the indoor temperature producing for many heats etc. along with wind direction Quick to fix is eased, and comfortableness improves.
Under the fast-refrigerating pattern from moment tm12 to moment tm14 shown in Figure 14, by three-dimensionally changing wind direction, the bias of indoor temperature is also eased, and comfortableness improves.
(5-6) as shown in Figure 9,, under quick heating mode, even if suppose indoor temperature toning, control device 80 does not make the operating frequency of compressor 51 lower than lower limit RL yet.That is, the moment tm0 under quick heating mode is to during tm4 constantly, the control that control device 80 does not make temperature controller cut out.
When being issued to after target temperature Tg at quick heating mode, estimate that indoor temperature, with respect to target temperature toning, if temperature controller is closed in the mode identical with common heating mode, will cause temperature sharply to descend degradation, variations in temperature is easily excessive.Therefore,, by temperature controller not being closed, the variation that can make to reach the indoor temperature after target temperature Tg flattens slow, makes not destroy comfortableness.
Under fast-refrigerating pattern, as shown in figure 14, control device 80 does not make the operating frequency of compressor 51 lower than lower limit RL equally.Under fast-refrigerating pattern, also temperature controller is not closed, the variation that can make thus to reach the indoor temperature after target temperature Tg flattens slow, makes not destroy comfortableness.
(5-7) control device 80 has been when being instructed to quick heating mode, from surpassing the moment tm2 of target temperature Tg through the moment tm4 of timer counting after predetermined time be the moment of predetermined time, finish quick heating mode.Like this, by make to finish quick heating mode when having passed through regular time, can after surpassing target temperature Tg, quick heating mode be finished reliably.And, observe tm4 constantly, can in the set time before end, approach lentamente stable indoor temperature.By quick heating mode reliably being finished and providing stable indoor temperature the finish time of heating mode fast, user easily utilizes quick heating mode.
When fast-refrigerating pattern, control device 80, at the moment tm1 of timer counting predetermined time from surpassing the moment tm12 of target temperature Tg, finishes fast-refrigerating pattern.Therefore, can after surpassing target temperature Tg, fast-refrigerating pattern be finished reliably, and stable indoor temperature can be provided in the finish time of fast-refrigerating pattern.
(5-8) at the remote controller 84 shown in Figure 10, being provided with for inputting the special-purpose action button of quick heating mode is start button 84g.Remote controller 84, after action button 84g is operated, sends to control device 80 indication that switches to quick heating mode from common heating mode.Like this, utilization is exclusively used in the start button 84g arranging to quick heating mode switching and switches to quick heating mode, thereby user can switch to rapidly quick heating mode.Therefore, can shorten the time that switches to quick heating mode, realize as early as possible comfortable state.
Also can be by start button 84g as the action button that is exclusively used in input fast-refrigerating pattern, user can switch to rapidly fast-refrigerating pattern.Therefore, can shorten the time that switches to fast-refrigerating pattern, realize as early as possible comfortable state.
