In notification mode, indoor be in the situation of the condition of high temperature or high wet condition, automatically urge the notice of entry into service according to indoor temperature and indoor humidity.
In air conditioner 1, when forcing to determine whether in the situation that begins to force to turn round in the operation mode or in notification mode, determine whether in the situation that begins to notify, use the process decision chart of relevant indoor temperature and indoor humidity.The process decision chart as shown in Figure 4 longitudinal axis represents indoor humidity (relative humidity), and transverse axis represents indoor temperature.
Below, illustrate and force operation mode.
Fig. 4 is an example of forcing the process decision chart in the operation mode, is set with high-temperature area, monitor area, standby zone in this process decision chart.High-temperature area is the indoor zone that is the condition of high temperature or high wet condition, needs to reduce indoor temperature or indoor humidity.The standby zone is the zone away from high-temperature area, is the zone that does not need to reduce indoor temperature or indoor humidity.Monitor area is the zone near high-temperature area, is the zone that indoor temperature or indoor humidity become high-temperature area easily.
In the process decision chart of Fig. 4, A point～F point is the following indoor temperature of expression and the point of indoor humidity.
The A point: indoor temperature is that 27 degree, indoor humidity are 100% points.
The B point: indoor temperature is that 27 degree, the point of indoor humidity between 70～80% are y 1
The C point: indoor temperature is that 33 degree, indoor humidity are 30% points.
The D point: indoor temperature is that 28 degree, indoor humidity are 100% points.
The E point: indoor temperature is that 28 degree, the point of indoor humidity between 70～80% are y 2
The F point: indoor temperature is that 34 degree, the point of indoor humidity between 30～40% are y 3
And, connect the line l that A point and B point and C are ordered 1Be the line between standby zone and the monitor area, connect the line l that D point and E point and F are ordered 2It is the line between monitor area and the high-temperature area.Therefore, shown in the process decision chart of Fig. 4, the standby zone is line l 1The zone of lower left, high-temperature area is line l 2Top-right zone (comprise that indoor temperature and indoor humidity are positioned at line l 2On situation), monitor area is that the zone that is sandwiched between high-temperature area and the standby zone (comprises that indoor temperature and indoor humidity are positioned at line l 1On situation).
Therefore, when the running of air conditioner 1 stops, switching in the situation of forcing operation mode, the running action when indoor temperature and indoor humidity are in the regional in high-temperature area and monitor area and standby zone is different.At this, force the running action of the regional behind the operation mode to describe to being switched to.
Be in the situation of high-temperature area in indoor temperature and indoor humidity, need to reduce indoor temperature or indoor humidity, thereby beginning cooling operation (forcing running).In air conditioner 1, forcing the cooling operation in the operation mode is the cooling operation of 28 ℃ of design temperatures.And than low 1 degree of design temperature when above when following (indoor temperature reach 27 degree), cooling operation is in (Thermo OFF) state that stops in indoor temperature.At this, dormant state refers to that compressor stops, indoor fan 16 driven states.In air conditioner 1, be at cooling operation in the situation of dormant state, little air quantity when being made as than cooling operation, and blade 17 is configured near the upper end of movable range up and down, and blow-off direction is changed to upwards.
In addition, be in the situation of monitor area in indoor temperature and indoor humidity, indoor temperature or indoor humidity become high-temperature area easily, thereby need suitable detection indoor temperature or indoor humidity, so the running of blowing.The air-supply running refers to that compressor stops, the 16 driven runnings of the indoor fan of indoor set.In air conditioner 1, indoor temperature transmitter 21 and indoor humidity sensor 22 are installed in the inside of indoor set 2, thereby when when running stops up and down blade 17 closures sometimes can not suitable detection go out indoor temperature and indoor humidity so that the inside of indoor set is full of in the situation of hot gas.Therefore, be in the situation of monitor area in indoor temperature and indoor humidity, by putting in blast running, air is at the internal circulation of indoor set 2, thereby can suitable detection go out indoor temperature and indoor humidity.At this, in the air-supply running when indoor temperature and indoor humidity are in monitor area, be made as the air quantity less than the air quantity of cooling operation, and blade 17 is configured near the upper end of movable range up and down, blow-off direction is changed to upwards.
In addition, be in the situation in standby zone in indoor temperature and indoor humidity, owing to do not need to reduce indoor temperature or indoor humidity away from high-temperature area, thereby do not carry out cooling operation or air-supply running.
Like this, in the present embodiment, when indoor temperature and indoor humidity in the pressure operation mode are in the situation of high-temperature area, begin cooling operation (forcing running).And behind the beginning cooling operation, when dormant state had continued the scheduled time, cooling operation stopped.
Below, the control of the pressure operation mode of air conditioner 1 is described with reference to Fig. 5.
At first, when the running of air conditioner 1 stopped, the pattern switching part 50(by controller 30 was with reference to Fig. 3 (b)) be switched to and force operation mode (step S1).At this, the situation that the indoor temperature when forcing operation mode to switching to and indoor humidity are in standby zone (with reference to Fig. 4) describes.
In forcing operation mode, judge whether be in monitor area (step S2) by indoor temperature transmitter 21 detected indoor temperatures with by indoor humidity sensor 22 detected indoor humidities.Become in the situation of high-temperature area from the standby zone in indoor temperature and indoor humidity, think after becoming monitor area from the standby zone, to become high-temperature area.Therefore, at step S2, whether be in monitor area according to indoor temperature and indoor humidity, judge whether indoor temperature and indoor humidity have approached the high-temperature area that needs the beginning cooling operation.
And, be judged to be indoor temperature and indoor humidity and be in the situation of monitor area (step S2: be), drive chamber's internal fan 16, putting in blast running (step S3).In near the situation of the monitor area indoor temperature and indoor humidity are in high-temperature area, by the putting in blast running, air is at the internal circulation of indoor set 2, thereby can suitable detection go out indoor temperature and indoor humidity.
On the other hand, be judged to be indoor temperature and indoor humidity not (step S2: no) in the situation at monitor area, because indoor temperature and indoor humidity are in the standby zone, thereby continue to carry out the judgement (step S2) whether indoor temperature and indoor humidity are in monitor area.
And, when after step S3 putting in blast running, judge whether be in monitor area (step S4) by indoor temperature transmitter 21 detected indoor temperatures with by indoor humidity sensor 22 detected indoor humidities.Be judged to be indoor temperature and indoor humidity and be in the situation of monitor area (step S4: be), because indoor temperature and indoor humidity are near the monitor area the high-temperature area, thereby the running (step S3) that continues to blow, make it possible to suitable detection and go out indoor temperature and indoor humidity.
On the other hand, be judged to be indoor temperature and indoor humidity not (step S4: no) in the situation at monitor area, thinking that indoor temperature and indoor humidity become standby zone or high-temperature area after the putting in blast running.Therefore, judge whether indoor temperature and indoor humidity are in standby zone (step S5).And, be judged to be indoor temperature and indoor humidity and be in the situation in standby zone (step S4: be), because indoor temperature and indoor humidity become the standby zone from the monitor area near high-temperature area, thereby out-of-blast running (step S6).Then, enter into step S2, judge whether indoor temperature and indoor humidity are in monitor area.On the other hand, be judged to be indoor temperature and indoor humidity not in the situation in standby zone (step S5: no), owing to being in high-temperature area, indoor temperature and indoor humidity need to reduce indoor temperature and indoor humidity, thereby beginning cooling operation (step S7).
Behind the beginning cooling operation, according to by indoor temperature transmitter 21 detected indoor temperature and design temperatures, judge whether cooling operation is dormant state (step S8).Air conditioner 1 is that 28 ℃ of design temperatures, indoor temperature are in dormant state when reaching below 27 ℃ at cooling operation.Therefore, at step S8, whether be below 27 ℃ according to indoor temperature, judge whether cooling operation is dormant state.And, be judged to be (step S8: no) in the situation that is not dormant state, because indoor temperature is higher than 27 ℃, thereby enters into step S7, continue to carry out cooling operation.
On the other hand, be judged to be (step S8: be) in the situation that cooling operation is dormant state, judging under dormant state, whether to become the temperature (step S9) that is higher than design temperature by indoor temperature transmitter 21 detected indoor temperatures.Being judged to be indoor temperature and becoming in the situation of the temperature that is higher than design temperature (step S9: be), enter into step S7, the beginning cooling operation.Being judged to be indoor temperature and not becoming in the situation of the temperature that is higher than design temperature (step S9: no), continue dormant state.
And, in the situation that continues dormant state, determine whether through the scheduled time (step S10).Being judged to be in the situation of having passed through the scheduled time under the dormant state (step S10: be), stop cooling operation (step S11).In air conditioner 1, after under dormant state, having passed through the scheduled time, stop cooling operation, thereby when cooling operation is stopped, even when indoor temperature and indoor humidity rise situation under, also can prevent the cooling operation that will begin in a minute.

[the 5th embodiment]
Below, with reference to Figure 10, Figure 11 the 5th embodiment of the present invention is described.The difference of the air conditioner of the air conditioner of the 5th embodiment and the 1st embodiment is, forces the period of running beginning.In addition, other structure is identical with above-mentioned the 1st embodiment, thereby also suitably the description thereof will be omitted to use identical label.
In the air conditioner of the 5th embodiment, judge that the process decision chart of the beginning of forcing running uses process decision chart shown in Figure 10.The longitudinal axis of process decision chart represents indoor humidity (relative humidity), and transverse axis represents indoor temperature.
As shown in figure 10, in process decision chart, be set with high-temperature area, high wet zone, monitor area, standby zone.High-temperature area shown in Figure 10 is the zone that needs to reduce indoor temperature or indoor humidity.High wet zone is the zone that needs to reduce indoor humidity.The standby zone is the zone away from high-temperature area and high wet zone, is the zone that does not need to reduce indoor temperature or indoor humidity.Monitor area is the zone near high-temperature area and high wet zone, is the zone that indoor temperature or indoor humidity become high-temperature area and high wet zone easily.
In the process decision chart of Figure 10, A 1Point～E 1Point is the following indoor temperature of expression and the point of indoor humidity.
A 1Point: indoor temperature is that 25 degree, the point of indoor humidity between 80～90% are y 4
B 1Point: indoor temperature is that 33 degree, indoor humidity are 30% points.
C 1Point: indoor temperature is that 25 degree, indoor humidity are 100% points.
D 1Point: indoor temperature is that 28 degree, the point of indoor humidity between 70～80% are y 2
E 1Point: indoor temperature is that 34 degree, the point of indoor humidity between 30～40% are y 3
F 1Point: indoor temperature is that 28 degree, indoor humidity are 100% points.
And, connect A 1Point and B 1The line l of point 11Be the line between standby zone and the monitor area, connect C 1Point and D 1The line l of point 12Be the line between monitor area and the high wet zone, connect D 1Point and E 1The line l of point 13Be the line between monitor area and the high-temperature area, connect D 1Point and F 1The line l of point 14It is the line between high wet zone and the high-temperature area.
Therefore, shown in the process decision chart of Figure 10, the standby zone is l 11The zone of lower left, high-temperature area is line l 13Upper right side, line l 14The zone on right side (comprise that indoor temperature and indoor humidity are positioned at line l 13Go up and line l 14On situation), high wet zone is line l 12Upper right side, line l 14The zone in left side (comprise that indoor temperature and indoor humidity are positioned at line l 12On situation), monitor area is that the zone that is sandwiched between high-temperature area and high wet zone and the standby zone (comprises that indoor temperature and indoor humidity are positioned at line l 11On situation).
Therefore, when the running of air conditioner stops, switching in the situation of forcing operation mode, the running action when indoor temperature and indoor humidity are in the regional in high-temperature area, high wet zone, monitor area and standby zone is different.At this, force the running action of the regional behind the operation mode to describe to being switched to.
In the present embodiment, force the pressure running of operation mode refer to dehumidify any one running in the cooling operation of 28 ℃ of running and design temperatures.
Be in the situation of high-temperature area in indoor temperature and indoor humidity, need to reduce indoor temperature or indoor humidity, thereby begin the cooling operation of 28 ℃ of design temperatures.And the cooling operation of forcing operation mode reaches 27 degree in indoor temperature and is in dormant state when following.
Be in the situation of high wet zone in indoor temperature and indoor humidity, indoor temperature is lower than 28 ℃, thereby does not need to reduce indoor temperature, but needs to reduce indoor humidity, thereby does not begin cooling operation, and begins the dehumidifying running.After forcing the dehumidifying of operation mode to operate to begin the dehumidifying running, be in indoor temperature and indoor humidity in the situation of high wet zone and be switched to cooling operation, become from high wet zone in indoor temperature and indoor humidity in the situation of monitor area and stop.And, be in the dehumidifying running of high wet zone in indoor temperature and indoor humidity, be made as the air quantity less than the air quantity of cooling operation, and blade 17 is configured near the upper end of movable range up and down, and blow-off direction is changed to upwards.And when switching to cooling operation after the dehumidifying running, the air quantity the when air quantity during the dehumidifying running is increased to cooling operation slowly increases air quantity when cooling operation.
And, being in the situation of monitor area in indoor temperature and indoor humidity, indoor temperature or indoor humidity become high-temperature area and indoor humidity easily, thereby need suitable detection indoor temperature or indoor humidity, so the running of blowing.
In addition, be in the situation in standby zone in indoor temperature and indoor humidity, do not need to reduce indoor temperature or indoor humidity, thereby do not blow running or cooling operation.
Like this, in the air conditioner of the 1st embodiment, when being in the situation of high-temperature area, indoor temperature and indoor humidity in the pressure operation mode begin cooling operation, and it is relative therewith, in the air conditioner of the 5th embodiment, in forcing operation mode, be in indoor temperature and indoor humidity in the situation of high-temperature area and begin cooling operation, and be in indoor temperature and indoor humidity in the situation of high-temperature area and begin the dehumidifying running.
And, in the air conditioner of the 5th embodiment, with the air conditioner of the 1st embodiment in the same manner, when under dormant state, having passed through the scheduled time, force the cooling operation in the operation mode to stop.On the other hand, force dehumidifying in the operation mode to operate to switch to when indoor temperature and indoor humidity become high-temperature area cooling operation, when indoor temperature and indoor humidity become monitor area, be stopped.
Below, the control of the pressure operation mode of air conditioner is described with reference to Figure 11.
At first, when the running of air conditioner stopped, the pattern switching part 50(by controller 30 was with reference to Fig. 3 (b)) be switched to and force operation mode (step S71).At this, the situation that the indoor temperature when forcing operation mode to switching to and indoor humidity are in the standby zone describes.
In forcing operation mode, judge whether be in monitor area (step S72) by indoor temperature transmitter 21 detected indoor temperatures with by indoor humidity sensor 22 detected indoor humidities.Become in the situation of high-temperature area or high wet zone from the standby zone in indoor temperature and indoor humidity, think after becoming monitor area from the standby zone, to become high-temperature area or high wet zone.Therefore, at step S72, whether be in monitor area according to indoor temperature and indoor humidity, judge whether indoor temperature and indoor humidity have approached high-temperature area and the high wet zone that need to begin to force running (cooling operation or dehumidifying running).
