The liquid refrigerant of two heat exchangers 15 outflow is depressurized in expansion valve 14, becomes the two phase refrigerant of low pressure.As low pressure
The refrigerant of two phase refrigerant flows into First Heat Exchanger 13, the air heat absorption flowed from wind path B, and the air is cooling, and
And heated and evaporated by the air, the gas refrigerant for becoming low pressure is flowed out from First Heat Exchanger 13.It is flowed from First Heat Exchanger 13
Gas refrigerant out is inhaled into compressor 11 by four-way valve 12.
(movement of the air under the second operation mode)
Fig. 3 is the psychrometric chart under the second operation mode of the air-conditioning device of embodiment 1.In addition, in Fig. 3, the longitudinal axis is
The absolute humidity of air, horizontal axis are the dry-bulb temperature of air.In addition, indicating that air is saturated air with curve C in Fig. 3
State.That is, on curve C, relative humidity 100%.
When air around air-conditioning device 100 becomes the state of a point shown in Fig. 3, the air stream enter wind path B it
Afterwards, it is cooled down by First Heat Exchanger 13.At this point, controlled in refrigerant circulation loop A using control device 90, so that the
Refrigerant temperature in one heat exchanger 13 is lower than the dew-point temperature of air, and therefore, the air is by the cooling simultaneously quilt of First Heat Exchanger 13
Dehumidifying, becomes the state of e point shown in Fig. 3, becomes low temperature and the high air of relative humidity.The sky flowed out from First Heat Exchanger 13
Gas flows into desiccant unit 23.At this point, the relative humidity due to the air is high, moisture is adsorbed by desiccant unit 23, the air
In the amount of moisture that contains reduce, which is further dehumidified.In addition, flowing into the air of desiccant unit 23 by along with suction
Attached heat of adsorption heating, the temperature of the air rise.Therefore, the air flowed out from desiccant unit 23 becomes f point shown in Fig. 3
State, become high temperature and low humidity.The air flowed out from desiccant unit 23 is heated by the second heat exchanger 15 after this, at
For the state of g point shown in Fig. 3, become high temperature.From the second heat exchanger 15 flow out air stream enter fan 24, from blow-off outlet 5 to
The outside of air-conditioning device 100 is discharged.
As described above, under the second operation mode, the refrigerant by using First Heat Exchanger 13 cooling and carry out
Dehumidifying (difference of the absolute humidity of the absolute humidity and e point of a point in Fig. 3) on the basis of, in addition utilize desiccant unit 23
Suction-operated carry out dehumidifying (difference of the absolute humidity of the absolute humidity and f point of the e point in Fig. 3).That is, by Fig. 2 and Fig. 3 ratio
Compared with it is found that in the second operation mode, when the first operation mode compared with can ensure more moisture removals.Therefore, air-conditioning fills
The dehumidification function for setting 100 is mainly realized by the second operation mode.
Also, the first operation mode and the second operation mode is alternately repeated in air-conditioning device 100.For example, continuing
In the case that the second operation mode is implemented on ground, the amount of the moisture being able to maintain due to desiccant unit 23 there are the upper limit, when
When by certain time, moisture is no longer adsorbed by desiccant unit 23, moisture removal decline.Therefore, air-conditioning device 100 is in desiccant
The amount for the moisture that unit 23 is kept is switched to the first operation mode close to the stage of the upper limit, and implementation makes moisture from desiccant unit
The operating of 23 desorptions.In this way, by alternately implementing the first operation mode and the second operation mode, to successively play desiccant
The absorption and desorption of unit 23 keep this effect for increasing moisture removal using the suction-operated of desiccant unit 23 long-term
Ground continues.
(opportunity of the switching of the first operation mode and the second operation mode)
Next, the opportunity of the switching of the first operation mode of explanation and the second operation mode.
The respective duration of runs of first operation mode and the second operation mode is set as and air conditions, air-conditioning device
The corresponding reasonable time such as 100 operating condition.In addition, the first operation mode and the respective operating of the second operation mode
Time is also possible to preset regular time.
The duration of runs appropriate of first operation mode is: the moisture of amount appropriate is desorbed from desiccant unit 23, remaining
The required time until the quantitative change of the moisture of desiccant unit 23 is amount appropriate.If remaining in desiccant unit 23
Moisture more than amount appropriate in the state of the first operation mode is switched to the second operation mode, then quilt in the second operation mode
The amount for the moisture that desiccant unit 23 adsorbs is reduced, and the moisture removal under the second operation mode reduces.On the contrary, if the first operating
The duration of runs of mode is too long, then the switching of the second operation mode to moisture removal more than the first operation mode becomes late, first
The duration of runs of operation mode it is later half, the state of moisture can not be desorbed due to continuing drying out agent unit 23 almost, when anti-
In the case where the switching for carrying out the first operation mode and the second operation mode again, the reduction of moisture removal becomes significant.
The duration of runs appropriate of second operation mode is: the moisture of amount appropriate is adsorbed in desiccant unit 23,
The amount for the moisture that desiccant unit 23 is kept becomes the time of amount appropriate.If can also be adsorbed in desiccant unit 23
The second operation mode is switched to the first operation mode in the state of leeway, then second fortune of the moisture removal more than the first operation mode
The duration of runs of rotary-die type shortens, therefore, when repeatedly carry out the switching of the first operation mode and the second operation mode the case where
Under, the reduction of moisture removal becomes significant.On the contrary, if the duration of runs of the second operation mode it is too long, in the second operational mode
Formula it is later half, continue drying out agent unit 23 can not adsorption moisture state, similarly moisture removal reduce.
Also, since the amount of the moisture of the holding of desiccant unit 23 is according to the relatively wet of the air for flowing into desiccant unit 2
It spends and changes, so the duration of runs appropriate of the first operation mode and the duration of runs appropriate of the second operation mode are according to stream
Enter the relative humidity of the air of desiccant unit 23 and changes.That is, when flowing into the high air of relative humidity to desiccant unit 23
In the case where, it is become difficult to desorb by the moisture that desiccant unit 23 is kept, on the contrary, the moisture that desiccant unit 23 adsorbs
Quantitative change is more.In addition, in the case where flowing into the low air of relative humidity to desiccant unit 23, the water of the holding of desiccant unit 23
Partial volume easily desorbs, on the contrary, the quantitative change for the moisture that desiccant unit 23 adsorbs is few.
Therefore, in air-conditioning device 100, according to the detection signal of humidity temperature pickup 81, the phase of sucking air is found out
To humidity, the first operation mode and the second operation mode respective duration of runs are correspondingly determined with the relative humidity.
Specifically, control device 90 stores the relative humidity (phase on the basis of record later of the benchmark as sucking air
To humidity) and the first operation mode and the second operation mode respective benchmark duration of runs, and according to actual sucking air
Relative humidity and benchmark relative humidity size relation, the time that the benchmark duration of runs is suitably increased and decreased is determined as first
Operation mode and the second operation mode respective duration of runs, first operation mode and the respective benchmark of the second operation mode
The duration of runs be by test or simulate in advance etc. it is acquiring, pass through the feelings of wind path B in the sucking air of the benchmark relative humidity
It can make more than moisture removal, the first operation mode and the second operation mode respective benchmark duration of runs under condition.
For example, control device 90 acted according to dehumidifying at the beginning of humidity temperature pickup 81 detection signal, find out
The relative humidity of actual sucking air.Then, in the case that the relative humidity is higher than pre-stored benchmark relative humidity,
Since the amount of the moisture desorbed under the first operation mode from desiccant unit 23 is than the relative humidity when actual sucking air
The amount of the moisture of desorption in the case where equal with benchmark relative humidity is few, so the duration of runs of the first operation mode is set
For the time longer than the benchmark duration of runs of preset first operation mode.In addition, due to being done under the second operation mode
The amount for the moisture that drying prescription unit 23 adsorbs is than the situation equal with benchmark relative humidity when the relative humidity of actual sucking air
Under absorption moisture amount it is more, so being set as the duration of runs of the second operation mode than preset second operational mode
Short time benchmark duration of runs of formula.
In addition, for example in the case that the relative humidity is lower than pre-stored benchmark relative humidity, due in the first fortune
The amount of the moisture desorbed under rotary-die type from desiccant unit 23 is opposite with benchmark wetter than the relative humidity for working as actual sucking air
Spend it is equal in the case where desorption moisture amount it is more, so being set as the duration of runs of the first operation mode than presetting
The first operation mode short time benchmark duration of runs.In addition, due to the suction of desiccant unit 23 under the second operation mode
The moisture adsorbed in the case that the amount of attached moisture is more equal with benchmark relative humidity than the relative humidity for working as actual sucking air
Amount it is few, so by the duration of runs of the second operation mode be set as than preset second operation mode benchmark operate when
Between long time.
In addition, in air-conditioning device 100, when switching to the second operation mode or when executing the second operation mode, control
The temperature determination unit 91 of device 90 processed according to the detection signal determining of humidity temperature pickup 81 suck air temperature whether be
Below preset fiducial temperature.Then, if being judged to sucking air in the temperature determination unit 91 of control device 90
Temperature is preset fiducial temperature hereinafter, then after that immediately or after the stand-by time by setting, control device
Defrosting movement is changed into third operation mode by 90 third operation mode configuration part 92.Third operation mode is in the first heat exchange
Make desiccant unit in the state that the surface temperature of device 13 is higher than the surface temperature of the First Heat Exchanger 13 under the second operation mode
The operation mode of 23 adsorption moistures.Stand-by time be store or calculate in third operation mode configuration part 92, to first
Time until blocking along with frosting occurs for heat exchanger 13.Stand-by time also can be set as the temperature phase with sucking air
The different times answered.That is, the temperature of sucking air is lower, stand-by time is set as the shorter time.When continuing
Third operation mode, when desiccant unit 23 has adsorbed the moisture of amount appropriate, control device 90 switches the flow path of four-way valve 12,
It is changed into the first operation mode.
Hereinafter, illustrating the movement of third operation mode.
(movement of the refrigeration cycle under third operation mode)
Under third operation mode, it is switched to shown in Fig. 1 dotted line with the flow path of the four-way valve 12 under the second operation mode
Flow path state, make compressor 11 stop.That is, under third operation mode, the circulation of the refrigerant of refrigerant circulation loop A
It being stopped, First Heat Exchanger 13 is not re-used as evaporator and plays a role, and the surface temperature of First Heat Exchanger 13 rises, in addition, the
Two heat exchangers 15 are not re-used as condenser and play a role.
(movement of the air under third operation mode)
Under third operation mode, the driving of the fan 24 under the second operation mode continues.Therefore, air-conditioning device 100
The air of surrounding flows into desiccant unit 23 after through First Heat Exchanger 13, and moisture is adsorbed and removed by desiccant unit 23
It is wet.The air flowed out from desiccant unit 23 passes through the second heat exchanger 15 after this, flows into fan 24, and from blow-off outlet 5 to
The outside of air-conditioning device 100 is discharged.
