[condensation prevents from operating]
Fig. 3 is the figure that an example of the action that operating is prevented to the condensation of the air conditioner described in Fig. 1 illustrates.Example
Such as, first, in Fig. 3 step S02, if the air conditioner 1 after receiving the instruction of user starts cooling operation or heating fortune
The air adjustment of the operation of air conditioner turned, then the indoor set 100A described in Fig. 1 and indoor set 100B progress interior.
In Fig. 3 step S04, if the indoor set 100 of more than 1 turns into operating dormant state, into step S06.
Indoors under the operating dormant state of machine 100, for example, the action of indoor machine fan 140 turns into halted state, expansion gear 104
As closed mode, shutter board 107 closes outlet 106.In addition, for example, indoor set 100 by receive the instruction of user and
As operating dormant state.In addition, for example, indoor set 100 is stopped, for interior by the timer operating realized using timer
Automatic operating in the case that the region that machine 100 is set reaches target temperature is stopped, and turns into operating dormant state.In addition, with
Under, indoor set 100A is illustrated as the example in the case of operating dormant state.
In the indoor set 100A in operating dormant state, the misgivings for producing condensation as described below be present.
For example, when air conditioner 1 just carries out cooling operation, in the indoor set 100A in operating dormant state, due to
Indoor machine fan 140A action stops, therefore is gradually reduced using the temperature around the heat exchanger 102A of side.In addition, hundred
In the case of impeller 107A closing outlets 106A, further increase is reduced using the temperature around the heat exchanger 102A of side.Separately
Outside, even if in the case where being closed expansion gear 104A, there is also cause expansion gear 104A simultaneously because of laying dust etc.
The situation for not completely closing but opening slightly, in this case, in using side heat exchanger 102A flowing have a small amount of low
The refrigerant of temperature, therefore gradually reduced using side heat exchanger 102A temperature.In addition, in order to suppress expansion gear 104A's
The misgivings that valve is fixed, sometimes also open expansion gear 104A slightly.As a result, in the indoor set 100A in operating dormant state
In, the temperature inside indoor set 100A is greatly reduced compared with the temperature of interior, when the indoor set in operating dormant state
In the case of the high proximal site of 100A humidity such as being arranged at bathroom or kitchen, the inside of machine 100A indoors be present
Or the misgivings of the generation such as outlet 106A condensation.If producing condensation, misgivings that dew drips to interior etc. be present.
In addition, for example, when air conditioner 1 just carries out heating operation, in the indoor set 100A in operating dormant state,
Because indoor machine fan 140A action stops, therefore it is gradually increasing using the temperature around the heat exchanger 102A of side.In addition,
In the case of shutter board 107A closing outlets 106A, the rising using the temperature around the heat exchanger 102A of side further increases
Greatly.Even if in addition, in the case where being closed expansion gear 104A, there is also cause expansion gear because of laying dust etc.
The situation that 104A is not completely closed but opened slightly, in this case, being flowed in using side heat exchanger 102A is had less
The refrigerant of the high temperature of amount, therefore be gradually increasing using side heat exchanger 102A temperature.In addition, in order to suppress expansion gear
The misgivings that 104A valve is fixed, sometimes also open expansion gear 104A slightly.In addition, it is accumulated in operating to suppress refrigerant
The indoor set 100A of dormant state, sometimes also opens expansion gear 104A slightly.As a result, in the room of operating dormant state
In interior machine 100A, the temperature inside indoor set 100A is substantially increased compared with the temperature of interior, in operating dormant state
In the case of the high proximal site of indoor set 100A humidity such as being arranged at bathroom or kitchen, machine indoors be present
The misgivings of the generations such as 100A inside condensation.If producing condensation, misgivings that dew drips to interior etc. be present.
Therefore, in the air conditioner 1 of the example of present embodiment, in step S06, it is used in operating dormant state
Indoor set 100A heat-exchanger temperature sensor 130A testing result, temperature sensor 132A testing result and humidity
Sensor 134A testing result, presumption is with the presence or absence of the possibility for producing condensation.
For example, in the case where air conditioner 1 just implements cooling operation, according to temperature sensor 132A testing result with
Humidity sensor 134A testing result calculates dew-point temperature.Then, using dew-point temperature and heat-exchanger temperature sensor
130A testing result, presumption is with the presence or absence of the possibility for producing condensation.
In addition, for example, in the case where air conditioner 1 just implements heating operation, according to heat-exchanger temperature sensor 130A
Testing result and humidity sensor 134A testing result calculate dew-point temperature.Then, sensed using dew-point temperature and room temperature
Device 132A testing result, presumption is with the presence or absence of the possibility for producing condensation.
Thus, for example, testing result and the testing result of heat-exchanger temperature sensor 130 to temperature sensor 132
Be compared, judge the high high-temperature temperature cryogenic temperature low with temperature of temperature, according to the testing result of humidity sensor 134 and
High-temperature temperature calculates dew-point temperature, and produces the possibility of condensation with cryogenic temperature presumption using dew-point temperature.
In the case of being estimated as there is a possibility that to produce condensation in step S06, into step S08.In step S08
In, stop the operating of the indoor set 100B in running well.For example, stopping the operating of the compressor 202 of outdoor unit 200, make room
Interior machine 100B expansion gear 104B turns into closed mode, stops indoor machine fan 140B action, and shutter board 107B is sealed
Close outlet 106B.
In step slo, convection current circuit switching device 204 switches over, and in step s 12, starting condensation prevents from operating.
When condensation prevents operating, be formed as making the expansion gear 104A of the indoor set 100A in operating dormant state turn into open shape
State, indoor machine fan 140A action is set to keep stopping, and shutter board 107A keeps closing outlet 106A state.So
Afterwards, act compressor 202.In condensation prevents operating, flow passage selector device 204 is switched, therefore heat exchanger temperature passes
Testing result of the testing result of sensor 130 close to temperature sensor 132.By approaching the temperature inside indoor set 100A
Indoor temperature, it can suppress to produce the misgivings of condensation.
In step S14, if heat-exchanger temperature sensor 130A testing result and temperature sensor 132A detection
As a result difference is changed into below threshold value, then into step S16 and terminating condensation prevents from operating.In addition, for example, air conditioner 1 just performs
Threshold value T2 when threshold value T1 during cooling operation is just performing heating operation from air conditioner 1 is different values but it is also possible to be identical
Value.
In step s 16, for example, stopping the operating of compressor 202, be formed as making the indoor set in operating dormant state
100A expansion gear 104A turns into closed mode, makes indoor machine fan 140A action keep stopping, and shutter board 107A
Closing outlet 106A state is kept, thus, terminating condensation prevents from operating.
In step S18, convection current circuit switching device 204 switches over, and in step S20, starts again at originally positive carry out
The indoor set 100A of normal operation operating.That is, the indoor set 100B expansion gear 104B just to be run well originally is made
As open mode, start indoor machine fan 140B action, and outlet 106A is formed as open shape by shutter board 107B
State, act compressor 202.
As above, the air conditioner 1 of the example of present embodiment has is cut using refrigerant piping connection compressor 202, stream
Changing device 204, heat source side heat exchanger 206, expansion gear 104 and using side heat exchanger 102 and formed, for refrigeration
The refrigerant loop 1A of agent circulation, in above-mentioned air conditioner 1, possesses to be arranged at interior and contain and utilizes side heat exchanger 102
Indoor set 100, indoor set 100 has：Carry out the indoor machine fan 140 towards the air-supply using side heat exchanger 102；Sensing chamber
The temperature sensor 132 of interior temperature；Detection utilizes the heat-exchanger temperature sensor 130 of the temperature of side heat exchanger 102；With
And it is accommodated in above-mentioned indoor set 100 and detects and passed with the humidity of the humidity using the air before the heat exchange of side heat exchanger 102
Sensor 134, during the operating of the out-of-blast indoor set 100 of machine fan 140 indoors of indoor set 100 is stopped, passed using room temperature
The testing result and heat-exchanger temperature sensor that testing result that sensor 132 detects, humidity sensor 134 detect
130 testing results detected, presumption produce the possibility of condensation, when there is a possibility that to produce condensation, flow path switching
Device 204 switches over, and execution makes the testing result of heat-exchanger temperature sensor 130 close to the detection of temperature sensor 132
As a result condensation prevents from operating.
For example, air conditioner 1 is also equipped with carrying out the control device of the control of air conditioner 1, control device is to temperature sensor 132
Testing result compared with the testing result of heat-exchanger temperature sensor 130, judge the high high-temperature temperature of temperature and temperature
Low cryogenic temperature is spent, dew-point temperature is calculated according to the testing result of humidity sensor 134 and high-temperature temperature, and use dew point
Temperature produces the possibility of condensation with cryogenic temperature presumption, and when there is a possibility that to produce condensation, performing condensation prevents from operating.
In addition, " control device " of the present utility model is equivalent to indoor set control device 150 or outdoor unit control device 250.
In addition, for example, when the testing result and the testing result of temperature sensor 132 of heat-exchanger temperature sensor 130
Difference when being changed into below threshold value, terminating condensation prevents from operating, and convection current circuit switching device 204 switches over.
In the air conditioner 1 of the example of present embodiment, perform by making the temperature inside indoor set 100 close to interior
Temperature come prevent condensation condensation prevent from operating, therefore, it is possible to suppress because perform condensation prevent operating cause interior

Consider.Also, in the air conditioner 1 of the example of present embodiment, due to out-of-blast when condensation prevents operating, therefore it can press down
The change of indoor temperature when system condensation prevents from operating.
For example, air conditioner 1 possesses more indoor sets 100 being connected in parallel with each other, the indoor set in stopping in the presence of operating
100 and when operating is stopped and just performing the indoor set 100 in the normal operation of cooling operation or heating operation, holding
When row condensation prevents operating, the indoor set 100 in normal operation stops indoor machine fan 140.By preventing from operating in condensation
When stop the indoor machine fan 140 of indoor set 100 in running well, the misgivings of indoor temperature change can be suppressed.
For example, more indoor sets 100 have expansion gear 104 respectively, when execution condensation prevents operating, in normal operation
Indoor set 100 reduce expansion gear 104 aperture.In addition, for example, perform condensation prevent operating when, in normal operation
Indoor set 100 closes expansion gear 104.By reducing the swollen of the indoor set 100 in running well when condensation prevents operating
The aperture of swollen device 104 closes the expansion gear 104, and the refrigerant of different temperatures flows into when can suppress and run well
Utilize this case of side heat exchanger 102.As a result, after condensation prevents operating from terminating, the interior that is just being run well originally
Machine 100 can recover rapidly to execution condensation to prevent the state before operating.
More indoor sets 100 have the shutter board 107 that the outlet 106 for discharging Air Conditioning is opened and closed respectively,
When performing condensation prevents operating, the indoor set 100 in normal operation closes shutter board 107.By preventing from transporting in execution condensation
Turn in advance to close the shutter board 107 of the indoor set 100 in normal operation, the change of indoor temperature can be suppressed.
The utility model is not limited to above-mentioned embodiment, and various change can be carried out in the scope of the utility model
Become.That is, the structure of above-mentioned embodiment can be suitably modified, alternatively, it is also possible to be replaced by other structures at least partially.And
And it is not configured and makes the constitutive requirements being particularly limited to and is not limited to disclosed in embodiment configuration, can be configured at can be real
The position of its existing function.
