Abstract

<P>PROBLEM TO BE SOLVED: To provide a humidity control device for controlling the humidity of air, shortening a length of time from starting until the relative humidity of room air reaches a target value. <P>SOLUTION: In the humidity control device, starting operation is performed at starting, and when a value detected by a humidity sensor 2 reaches a target value during starting operation, the starting operation is changed over into normal operation. During the starting operation when the temperature of second air to be fed from a regenerating heat exchanger 102 to adsorbing elements 81, 82 on the regeneration side is higher than during the normal operation, water desorbing from an adsorbing agent is increased more than during the normal operation. During the starting operation, the humidified amount of the second air in the adsorbing elements 81, 82 on the regeneration side is therefore increased more than during the normal operation. Along therewith, the amount of water remaining in the adsorbing elements 81, 82 on the regeneration side is reduced at the time of finishing regenerating operation, and so the dehumidified amount from first air in the adsorbing elements 81, 82 on the adsorption side is increased during the starting operation. <P>COPYRIGHT: (C)2005,JPO&amp;NCIPI

Description

  The present invention relates to a humidity control device that adjusts the humidity of air.

  Conventionally, as disclosed in Patent Document 1, a humidity control apparatus that adjusts the humidity of air is known. This humidity control apparatus performs dehumidification or humidification of air supplied to a room by using two adsorbing elements alternately by switching the flow paths of the first air and the second air. The casing of the humidity control apparatus is provided with a refrigerant circuit and two adsorption elements carrying an adsorbent. The refrigerant circuit is provided with a cooling heat exchanger that functions as an evaporator and a regenerative heat exchanger that functions as a condenser.

In the humidity control apparatus, the moisture contained in the first air taken into the casing is adsorbed by one adsorption element. The first air deprived of moisture exchanges heat with the refrigerant while passing through the cooling heat exchanger and radiates heat to the refrigerant. On the other hand, the second air taken into the casing is heated by exchanging heat with the refrigerant while passing through the regenerative heat exchanger, and then supplied to the other adsorption element. In the other adsorption element, moisture is desorbed from the heated adsorbent, and the desorbed moisture is imparted to the second air. In the dehumidifying operation, the dehumidified first air is supplied to the room and the second air is discharged to the outside. During the humidifying operation, the humidified second air is supplied to the room and the first air is discharged to the outside.

-Action-
In the first and second inventions, the humidity control device is provided with the fan (95, 96), the adsorption element (81, 82), and the heating means (1). When the fan (95, 96) is operated, the first air and the second air are taken in. Of these, the first air is sent to the adsorption element (81, 82). Moisture in the first air is adsorbed by the adsorption elements (81, 82). That is, the adsorption operation is performed in the humidity control apparatus. On the other hand, the second air is heated by the heating means (1) and then sent to the adsorption element (81, 82). In the adsorbing element (81 82), the adsorbent is heated by the second air, and moisture is desorbed from the adsorbent. The second air is given this desorbed moisture. That is, the regeneration operation is performed in the humidity control apparatus. Then, one of the first air and the second air after passing through the adsorption element (81, 82) is supplied into the room and the other is discharged out of the room.

  In the present invention, the humidity control apparatus operates at startup until a predetermined reference condition is satisfied after the startup. This start-up operation is performed to make the temperature of the second air sent from the heating means (1) to the adsorption element (81, 82) higher than after the predetermined reference condition is satisfied. Then, during the start-up operation in which the temperature of the second air sent from the heating means (1) to the adsorption element (81, 82) becomes higher than after the predetermined reference condition is satisfied, after the predetermined reference condition is satisfied. Also, moisture desorbed from the adsorbent increases. For this reason, during the startup operation, the amount of humidification to the second air in the adsorption element (81, 82) that is the target of the regeneration operation increases after the predetermined reference condition is satisfied. Along with this, the amount of moisture remaining in the adsorption element (81, 82) at the end of the regeneration operation also decreases. For this reason, during the startup operation, the amount of dehumidification from the first air in the adsorption element (81, 82) that is the subject of the adsorption operation also increases.

  In the first invention, the humidity control device is provided with the refrigerant circuit (100) including the regenerative heat exchanger (102), the first heat exchanger (103), and the second heat exchanger (104). The second air is heated by the regenerative heat exchanger (102) and then sent to the adsorption element (81, 82). The first air and the second air that have passed through the adsorption element (81, 82) pass through the first heat exchanger (103) toward the outside and the second heat exchanger (104) toward the room. Pass through.

In the first and second aspects of the invention, in the refrigerant circuit (100) operating at the time of startup, the regenerative heat exchanger (102) serves as a condenser, and the first heat exchanger (103) and the second heat exchanger (104 ) Is a refrigeration cycle in which both are evaporators. Then, the refrigerant circulating in the refrigerant circuit (100) absorbs heat from the air that goes to the outside by the first heat exchanger (103) and from the air that goes to the room by the second heat exchanger (104). The heat is dissipated to the second air by the vessel (102).

  On the other hand, in the refrigerant circuit (100) during normal operation after the establishment of the reference condition, the regenerative heat exchanger (102) serves as a condenser, and the first heat exchanger (103) and the second heat exchanger (104) A refrigeration cycle is performed in which only the direction through which the first air passes becomes an evaporator. The refrigerant circulating in the refrigerant circuit (100) absorbs heat from the first air when the first air passes through the first heat exchanger (103) and the second heat exchanger (104), and regenerates heat. The heat is dissipated to the second air by the vessel (102).

In the said 3rd invention, a humidity detection means (2) is provided in a humidity control apparatus. The reference condition in the present invention is satisfied when the detection value of the humidity detecting means (2) reaches a predetermined reference value. During the operation of the humidity control device, the relative humidity of the room air is detected by the humidity detection means (2). Then, when the detected value of the humidity detecting means (2) reaches a predetermined reference value, the operation is switched from the startup operation to the normal operation.

In the said 4th invention, a temperature detection means is provided in a humidity control apparatus. The reference condition in the present invention is satisfied when the detected value of the temperature detecting means reaches a predetermined reference value. During operation of the humidity control device, the temperature of the room air is detected by the temperature detection means, and when the detected value of the temperature detection means reaches a predetermined reference value, the operation is switched from the startup operation to the normal operation.

  Here, for example, in winter, the relative humidity remains substantially constant even if the temperature of the outdoor air varies. Therefore, when the temperature of the outdoor air is low, the absolute humidity is also low, and the absolute humidity of the air supplied to the room is low. And since the temperature of outdoor air is low, the temperature of room air rises only moderately, and since the absolute humidity of the air supplied indoors is low, the relative humidity of room air rises only moderately. On the other hand, when the temperature of the outdoor air is high, the absolute humidity is also high, and the absolute humidity of the air supplied to the room is high. And since the temperature of outdoor air is high, the temperature of room air rises rapidly, and since the absolute humidity of the air supplied indoors is high, the relative humidity of room air also rises rapidly.

  Thus, the higher the temperature rise rate of the room air, the higher the relative humidity rise rate. Conversely, the lower the room air temperature rise rate, the lower the relative humidity rise rate. That is, there is a correlation between the temperature of the room air and the relative humidity, and both change in conjunction with each other. Therefore, the relative humidity of the room air can be estimated from the detection value of the temperature detection means. Therefore, in the present invention, when the detected value of the temperature detecting means reaches a predetermined reference value, it is determined that the relative humidity of the indoor air has reached the target value, and switching from the startup operation to the normal operation is performed.

In the fifth aspect, the humidity control device is provided with a timer. The reference condition in the present invention is satisfied when the elapsed time from the start time measured by the timer reaches a predetermined reference value. During the operation of the humidity controller, the elapsed time from the startup is detected by the timer, and when the measured value of the timer reaches a predetermined reference value, the startup operation is switched to the normal operation.

  Here, if a test is performed in advance under various operating conditions and the elapsed time from when the humidity control device starts up until the relative humidity of the room air reaches the target value is measured, it is based on the data obtained in that test. The elapsed time from the start time when the relative humidity of the room air is expected to reach the target value can be set as the reference value. Therefore, in the present invention, when the measured value of the timer reaches a predetermined reference value, it is determined that the relative humidity of the room air has reached the target value, and switching from the startup operation to the normal operation is performed.

In the first and second aspects of the invention, the startup operation is performed after the startup until a predetermined reference condition is satisfied. During the start-up operation, the temperature of the second air sent from the heating means (1) to the adsorption element (81, 82) becomes higher than after the predetermined reference condition is satisfied, and the amount of moisture desorbed from the adsorbent is reduced. To increase. During the start-up operation, the dehumidification amount from the first air or the regeneration operation is performed by the adsorption element (81, 82) that is the target of the adsorption operation after the predetermined reference condition is satisfied. The amount of humidification to the second air in the adsorbing elements (81, 82) increases. Therefore, according to the present invention, in the humidity control apparatus that adjusts the humidity of the air, it is possible to shorten the time from when the relative humidity of the room air reaches the target value after the activation.

In the first and second inventions, both the first heat exchanger (103) and the second heat exchanger (104) serve as an evaporator during the startup operation, and the first heat exchanger (103 during the normal operation). ) And the second heat exchanger (104), only the one through which the first air passes becomes an evaporator. That is, during the start-up operation, the surface area of the heat exchanger serving as an evaporator is larger than during normal operation. For this reason, during the start-up operation, the refrigerant evaporating temperature can be made higher than during normal operation while ensuring the amount of heat that the refrigerant absorbs from the air. And since the low pressure of a refrigerating cycle becomes high, the high pressure of a refrigerating cycle also rises in connection with it, and the condensation temperature of the refrigerant | coolant in a condenser becomes high.

  Therefore, according to the present invention, during start-up operation, the temperature of the second air sent from the regenerative heat exchanger (102) to the adsorption element (81, 82) can be made higher than during normal operation, The amount of dehumidification from the first air at the adsorption element (81, 82) that is the target of the adsorption operation than during normal operation and the second air at the adsorption element (81, 82) that is the target of the regeneration operation The amount of humidification can be increased.

In the third aspect of the invention, when the detected value of the humidity detecting means (2) for detecting the humidity of the room air reaches a predetermined reference value, the operation is switched from the startup operation to the normal operation. Therefore, according to the present invention, the humidity can be accurately adjusted by the humidity detecting means (2), and the indoor comfort can be maintained.

In the fourth aspect of the invention, when the detected value of the temperature detecting means for detecting the temperature of the indoor air reaches a predetermined reference value, the operation at the time of startup is switched to the normal operation. As described above, since there is a correlation between the temperature of the room air and the relative humidity, the relative humidity of the room air can be estimated from the detection value of the temperature detection means. Therefore, according to the present invention, switching from the startup operation to the normal operation can be performed at an appropriate timing using the temperature detection means.

In the fifth aspect of the invention, when the measured value of the timer that measures the elapsed time from the startup reaches a predetermined reference value, the startup operation is switched to the normal operation. As described above, if the elapsed time from the start-up when the relative humidity of the indoor air is expected to reach the target value is set as a reference value by performing a test in advance, the relative humidity of the indoor air is estimated from the measured value of the timer. can do. Therefore, according to the present invention, switching from the startup operation to the normal operation can be performed at an appropriate timing using the timer.

-Operation control at startup-
The operation control at the time of starting in the humidity control apparatus will be described.

<Humidification operation>
When the humidification operation is started, the humidity control apparatus performs an activation operation immediately after activation, and then switches from the activation operation to the normal operation.

  In the startup operation, in the refrigerant circuit (100), the first electric expansion valve (111) is closed, and the opening degree of the second electric expansion valve (112) is appropriately adjusted according to the operating conditions.

  As shown in FIGS. 6 and 7, the refrigerant discharged from the compressor (101) exchanges heat with the second air in the regenerative heat exchanger (102), dissipates heat to the second air, and condenses. The refrigerant condensed in the regenerative heat exchanger (102) flows into the second heat exchanger (104) after passing through the second electric expansion valve (112). In the second heat exchanger (104), the refrigerant exchanges heat with the second air, absorbs heat from the second air, and evaporates. The refrigerant evaporated in the second heat exchanger (104) is sucked into the compressor (101) and compressed.

  On the other hand, when the detected value of the humidity sensor (2) reaches a predetermined reference value (here, relative humidity 40%) during the startup operation of the humidity control device, the startup operation is switched to the normal operation. In normal operation, in the refrigerant circuit (100), the second electric expansion valve (112) is closed, and the opening degree of the first electric expansion valve (111) is appropriately adjusted according to the operating conditions.

  As shown in FIGS. 6 and 8, the refrigerant discharged from the compressor (101) exchanges heat with the second air in the regenerative heat exchanger (102), dissipates heat to the second air, and condenses. The refrigerant condensed in the regenerative heat exchanger (102) flows into the first heat exchanger (103) after passing through the first electric expansion valve (111). In the first heat exchanger (103), the refrigerant exchanges heat with the first air, absorbs heat from the first air, and evaporates. The refrigerant evaporated in the first heat exchanger (103) is sucked into the compressor (101) and compressed.

  Here, in the winter, an example will be described in which the temperature of the outdoor air (OA) when starting the humidity control device is about 0 ° C. and the temperature of the indoor air (RA) is about 10 to 15 ° C. In this state, the temperature of the 1st air taken in in a casing (10) will be about 0 degreeC, and the temperature of the 2nd air taken in in a casing (10) will be about 10-15 degreeC.

  As shown in FIGS. 7 and 8, the first air flows into the first heat exchanger (103) after moisture is adsorbed by the first adsorption element (81). The second air is heated by the regenerative heat exchanger (102), regenerates the second adsorption element (82), and then flows into the second heat exchanger (104). In addition, in order to regenerate the second adsorption element (82), it is necessary to heat the second air to a relatively high temperature in the regenerative heat exchanger (102), and after passing through the second adsorption element (82) The temperature of the second air is also relatively high. The temperature of the first air flowing into the first heat exchanger (103) is about 10 ° C., and the temperature of the second air flowing into the second heat exchanger (104) is about 35 ° C.

  In addition, heat exchange is performed between the second air passing through the second heat exchanger (104) and the refrigerant during the startup operation, and the first heat exchanger (103) is passed during the normal operation. Heat exchange is performed between the first air and the refrigerant. As described above, the temperature of the second air flowing into the second heat exchanger (104) is higher than the temperature of the first air flowing into the first heat exchanger (103). For this reason, during the start-up operation in which the second air exchanges heat with the refrigerant in the second heat exchanger (104), compared to during the normal operation in which the first air exchanges heat with the refrigerant in the first heat exchanger (103). As a result, the evaporation temperature of the refrigerant increases. And since the low pressure of a refrigerating cycle becomes high, the high pressure of a refrigerating cycle also rises in connection with it, and the condensation temperature of the refrigerant | coolant in a regenerative heat exchanger (102) becomes high.

  Therefore, during the start-up operation, the temperature of the second air after heat exchange with the refrigerant in the regenerative heat exchanger (102) becomes higher than during normal operation, and the second adsorbing element from the regenerative heat exchanger (102). The temperature of the 2nd air sent to (82) becomes high. Moreover, when the temperature of the 2nd air sent to a 2nd adsorption element (82) becomes high, the water | moisture content isolate | separated from the adsorption agent of a 2nd adsorption element (82) will increase. For this reason, the amount of humidification to the 2nd air in the 2nd adsorption element (82) increases during operation at the time of starting compared with normal operation.

<Dehumidifying operation>
When the dehumidifying operation is started, the humidity control apparatus performs a startup operation immediately after startup, and then switches from the startup operation to the normal operation.

  In the startup operation, in the refrigerant circuit (100), the second electric expansion valve (112) is closed, and the opening degree of the first electric expansion valve (111) is appropriately adjusted according to the operating conditions.

  As shown in FIGS. 6 and 9, the refrigerant discharged from the compressor (101) exchanges heat with the second air in the regenerative heat exchanger (102), dissipates heat to the second air, and condenses. The refrigerant condensed in the regenerative heat exchanger (102) flows into the first heat exchanger (103) after passing through the first electric expansion valve (111). In the first heat exchanger (103), the refrigerant exchanges heat with the second air, absorbs heat from the second air, and evaporates. The refrigerant evaporated in the first heat exchanger (103) is sucked into the compressor (101) and compressed.

  On the other hand, when the detected value of the humidity sensor (2) reaches a predetermined reference value (here, the relative humidity is 47%) during the startup operation of the humidity control device, the startup operation is switched to the normal operation. In normal operation, in the refrigerant circuit (100), the first electric expansion valve (111) is closed, and the opening degree of the second electric expansion valve (112) is appropriately adjusted according to the operating conditions.

  As shown in FIGS. 6 and 10, the refrigerant discharged from the compressor (101) exchanges heat with the second air in the regenerative heat exchanger (102), dissipates heat to the second air, and condenses. The refrigerant condensed in the regenerative heat exchanger (102) flows into the second heat exchanger (104) after passing through the second electric expansion valve (112). In the second heat exchanger (104), the refrigerant exchanges heat with the first air, absorbs heat from the first air, and evaporates. The refrigerant evaporated in the second heat exchanger (104) is sucked into the compressor (101) and compressed.

  As shown in FIGS. 9 and 10, the first air flows into the second heat exchanger (104) after moisture is adsorbed by the first adsorption element (81). The second air is heated by the regenerative heat exchanger (102), regenerates the second adsorption element (82), and then flows into the first heat exchanger (103). Further, in order to regenerate the second adsorption element (82), the second air is heated to a relatively high temperature in the regenerative heat exchanger (102), and accordingly, after passing through the second adsorption element (82). The temperature of the second air is also relatively high. And the temperature of the 2nd air which flows in into a 1st heat exchanger (103) becomes higher than the temperature of the 1st air which flows into a 2nd heat exchanger (104).

  In addition, heat is exchanged between the second air passing through the first heat exchanger (103) and the refrigerant during the startup operation, and passes through the second heat exchanger (104) during the normal operation. Heat exchange is performed between the first air and the refrigerant. As described above, the temperature of the second air flowing into the first heat exchanger (103) is higher than the temperature of the first air flowing into the second heat exchanger (104). For this reason, the start-up operation in which the second air exchanges heat with the refrigerant in the first heat exchanger (103) is compared with the normal operation in which the first air exchanges heat with the refrigerant in the second heat exchanger (104). As a result, the evaporation temperature of the refrigerant increases. And since the low pressure of a refrigerating cycle becomes high, the high pressure of a refrigerating cycle also rises in connection with it, and the condensation temperature of the refrigerant | coolant in a regenerative heat exchanger (102) becomes high.

  Therefore, during the start-up operation, the temperature of the second air after heat exchange with the refrigerant in the regenerative heat exchanger (102) becomes higher than during normal operation, and the second air flowing into the second adsorption element (82) flows. As the temperature of the air increases, the moisture desorbed from the adsorbent of the adsorption element (82) increases. That is, during the start-up operation, the amount of moisture applied to the second air by the second adsorption element (82) increases more than during normal operation. Further, since the amount of moisture desorbed from the second adsorption element (82) during the start-up operation increases, the amount of moisture remaining in the second adsorption element (82) at the end of the regeneration operation also decreases. Therefore, during the startup operation, the amount of dehumidification from the first air in the second adsorption element (82) also increases.

-Effect of Reference Form 1-
In the present embodiment, the startup operation is performed until the detected value of the humidity sensor (2) reaches a predetermined reference value after startup. Of the first heat exchanger (103) and the second heat exchanger (104), only the one through which the second air passes becomes an evaporator during the start-up operation, and during the normal operation, the first heat exchanger (103 ) And the second heat exchanger (104), only the one through which the first air passes becomes an evaporator.

  Here, the first air is adsorbed by the adsorption element (81, 82) on the adsorption side and then flows into the evaporator, and the second air is heated by the regeneration heat exchanger (102) and then adsorbed on the regeneration side. The element (81, 82) is regenerated and then flows into the evaporator. In addition, in order to regenerate the adsorption element (81, 82) on the regeneration side, it is necessary to heat the second air to a relatively high temperature in the regeneration heat exchanger (102), and this adsorption element (81, 82) The temperature of the second air after passing through becomes relatively high. For this reason, during the start-up operation in which the second air exchanges heat with the refrigerant in the evaporator, the evaporation temperature of the refrigerant becomes higher than in the normal operation in which the first air exchanges heat with the refrigerant in the evaporator. And since the low pressure of a refrigerating cycle becomes high, the high pressure of a refrigerating cycle also rises in connection with it, and the condensation temperature of the refrigerant | coolant in a condenser becomes high.

  Therefore, during the start-up operation, the temperature of the second air sent from the regeneration heat exchanger (102) to the regeneration-side adsorption element (81, 82) can be made higher than during normal operation. The humidification amount to the second air at (81, 82) can be increased. Along with this, the amount of moisture remaining in the regeneration-side adsorption element (81, 82) at the end of the regeneration operation also decreases. For this reason, during the startup operation, the amount of dehumidification from the first air in the adsorption element (81, 82) on the adsorption side can be increased. Therefore, according to this embodiment, in the humidity control apparatus that adjusts the humidity of the air, the time from when the relative humidity of the room air (RA) reaches the target value after activation can be shortened.

  In the present embodiment, when the detected value of the humidity sensor (2) that detects the humidity of the room air (RA) reaches a predetermined reference value, the operation is switched from the startup operation to the normal operation. Therefore, according to the present embodiment, the humidity of the room air (RA) can be accurately adjusted by the humidity sensor (2), and the comfort in the room can be maintained.

-Modification of Reference Form 1-
You may change the structure of the humidity control apparatus of the said reference form 1. FIG. Here, this modification will be described with respect to differences from the first embodiment.

  The humidity control apparatus of the present modification is provided with a temperature sensor (not shown) as temperature detection means instead of the humidity sensor (2) for detecting the relative humidity of the room air (RA). This temperature sensor is for detecting the temperature of indoor air (RA), and is provided in the vicinity of the indoor inlet (15) in the casing (10).

  In the humidity controller, the temperature of the room air (RA) taken into the casing (10) is detected by a temperature sensor. In the humidity control apparatus, the startup operation is performed at the time of startup, and when the detected value of the temperature sensor reaches a predetermined reference value during the startup operation, the operation is switched to the normal operation.

  Here, for example, in winter, even if the temperature of the outdoor air (OA) varies, the relative humidity is about 80%. Further, during the humidifying operation of the humidity control apparatus, the humidification amount and the heating amount to the air (SA) supplied to the room are constant. Therefore, if the temperature of the outdoor air (OA) taken into the casing (10) is low, the absolute humidity is also low, and the amount of moisture in the outdoor air (OA) adsorbed by the adsorption element (81, 82) on the adsorption side is low. The temperature of the adsorption element (81, 82) does not increase so much as it decreases. For this reason, in the adsorption element (81, 82) on the adsorption side, the heating amount to the air (SA) supplied to the room is reduced, and accordingly, the air supplied to the room in the adsorption element (81, 82) on the regeneration side. Less humidification for (SA). And since the temperature of outdoor air (OA) is low, the temperature of room air (RA) rises only moderately, and since the absolute humidity of the air (SA) supplied indoors is low, Relative humidity also rises only slowly.

  On the other hand, when the temperature of the outdoor air (OA) taken into the casing (10) is high, the absolute humidity is high, and the absolute humidity of the air (SA) supplied into the room is high. And since the temperature of outdoor air (OA) is high, the temperature of indoor air (RA) rises quickly, and the relative humidity of indoor air (RA) is high because the absolute humidity of air (SA) supplied to the room is high. Will rise quickly.

  Thus, if the temperature rise rate of the indoor air (RA) is high, the relative humidity rise rate is also high. Conversely, if the temperature rise rate of the room air (RA) is low, the relative humidity rise rate is low. Become. That is, there is a correlation between the temperature of the indoor air (RA) and the relative humidity, and both change in conjunction with each other. Therefore, the relative humidity of room air (RA) can be estimated from the detected value of the temperature sensor. Therefore, the relative humidity of the indoor air (RA) is set to a target value by setting the predetermined reference value to a target value (40% during the humidifying operation and 47% during the dehumidifying operation). When the value is reached, the startup operation can be switched to the normal operation.

  Further, a database may be provided in the humidity control apparatus, and the reference value may be changed using this database. As described above, when the temperature of the outdoor air (OA) is low, the temperature of the air (SA) supplied to the room is low, and the temperature rise rate of the room air (RA) is low. Further, when the temperature of the outdoor air (OA) is high, the temperature of the air (SA) supplied to the room is high, and the temperature rise rate of the room air (RA) is high. For this reason, a database for setting reference values based on temperature data of outdoor air (OA), air supplied to the room (SA), and room air (RA) is provided in the humidity controller, and the outdoor air (OA ) By measuring the temperature of the indoor air (SA) and indoor air (RA) with a temperature sensor and setting a reference value, the accuracy of the estimated relative humidity of the indoor air (RA) can be improved. Can be improved.

  In the present modification, when the detected value of the temperature sensor that detects the temperature of the indoor air (RA) reaches a predetermined reference value, the operation is switched from the startup operation to the normal operation. As described above, since there is a correlation between the temperature of the room air (RA) and the relative humidity, the relative humidity of the room air (RA) can be estimated from the detection value of the temperature sensor. Therefore, according to this modification, it is possible to switch from the startup operation to the normal operation at an appropriate timing using the temperature sensor.

<< Embodiment of the Invention >>
The embodiment of the present invention is such that the startup operation is changed in the humidity control apparatus of the above reference embodiment. Here, the difference between the present embodiment and the first embodiment will be described.

  In the humidity control apparatus of the present embodiment, the opening degree of the first electric expansion valve (111) and the second electric expansion valve (112) is appropriately adjusted according to the operating conditions in the startup operation during the humidifying operation and the dehumidifying operation. Is done. In this state, the refrigerant circulating in the refrigerant circuit (100) is diverted after passing through the regenerative heat exchanger (102) and flows into the first heat exchanger (103) and the second heat exchanger (104). . 11 and 12, the regenerative heat exchanger (102) serves as a condenser, and both the first heat exchanger (103) and the second heat exchanger (104) serve as an evaporator. That is, in the start-up operation of the present embodiment, unlike the first embodiment, the first heat exchanger (103) and the second heat exchanger (104) through which the first air passes is also an evaporator.

  On the other hand, when the detected value of the humidity sensor (2) reaches a predetermined reference value during the startup operation, the startup operation is switched to the normal operation. In the normal operation during the humidifying operation and the dehumidifying operation, only the first heat exchanger (103) and the second heat exchanger (104) through which the first air passes becomes an evaporator. The normal operation during the humidifying operation and the dehumidifying operation is the same as in the first embodiment.

  As described above, the surface area of the heat exchanger, which serves as an evaporator, is larger during startup operation than during normal operation. For this reason, during the start-up operation, the evaporation temperature of the refrigerant can be made higher than that during the normal operation while the amount of heat that the refrigerant absorbs from the first air and the second air is secured. And since the low pressure of a refrigerating cycle becomes high, the high pressure of a refrigerating cycle also rises in connection with it, and the condensation temperature of the refrigerant | coolant in a regenerative heat exchanger (102) becomes high.

  Therefore, during the start-up operation, the temperature of the second air sent from the regeneration heat exchanger (102) to the regeneration-side adsorption element (81, 82) can be made higher than during normal operation. For this reason, the moisture desorbed from the adsorbent of the adsorption element (81, 82) on the regeneration side increases, and the humidification amount to the second air in the adsorption element (81, 82) increases. Along with this, the amount of moisture remaining in the regeneration-side adsorption element (81, 82) at the end of the regeneration operation also decreases. For this reason, during the startup operation, the amount of dehumidification from the first air in the adsorption element (81, 82) on the adsorption side also increases.

-Modification of the embodiment-
In the humidity control apparatus of the said embodiment, you may change the structure of a humidity control apparatus. Here, this modification will be described with respect to differences from the above embodiment.

  In the humidity control apparatus of the present modification, the first heat exchanger (103) and the second heat exchanger (104) provided in the refrigerant circuit (100) are connected in series in the refrigerant circulation direction during the startup operation. Yes.

  Specifically, as shown in FIG. 13, in the startup operation during the humidifying operation, the refrigerant discharged from the compressor (101) passes through the regenerative heat exchanger (102) and then passes through the first heat exchanger (103). Flow into. The refrigerant that has absorbed heat from the first air in the first heat exchanger (103) flows into the second heat exchanger (104) and absorbs heat from the second air. The refrigerant after passing through the second heat exchanger (104) is returned to the compressor (101).

  On the other hand, as shown in FIG. 14, in the startup operation during the dehumidifying operation, the refrigerant discharged from the compressor (101) flows into the second heat exchanger (104) after passing through the regenerative heat exchanger (102). To do. The refrigerant that has absorbed heat from the first air in the second heat exchanger (104) flows into the first heat exchanger (103) and absorbs heat from the second air. The refrigerant after passing through the first heat exchanger (103) is returned to the compressor (101).

-Modification 2 of embodiment-
In the humidity control apparatus of the said embodiment, you may change the structure of a humidity control apparatus. Here, this modification will be described with respect to differences from the above embodiment.

  In the humidity control apparatus of this modification, a timer (not shown) is provided instead of the humidity sensor (2) for detecting the relative humidity of the room air (RA). This timer is for measuring the elapsed time from the startup of the humidity control device.

  In the humidity control apparatus, in each operation of the humidifying operation and the dehumidifying operation, the startup operation is performed at the time of startup, and when the measured value of the timer reaches a predetermined reference value during the startup operation, the operation is switched to the normal operation. .

  Here, tests are performed under various operating conditions in advance, and the elapsed time from when the humidity control device starts up until the relative humidity of the room air (RA) reaches the target value (40% during humidification operation and 47% during dehumidification operation). Can be set as a reference value based on the data obtained in the test, the elapsed time from the start-up when the relative humidity of the room air (RA) is expected to reach the target value.

  In this modification, when the measured value of the timer that measures the elapsed time from the start reaches a predetermined reference value, the operation at the start is switched to the normal operation. As described above, if the test is performed in advance and the elapsed time from the start-up when the relative humidity of the room air (RA) is expected to reach the target value is set as the reference value, the room air (RA) ) Relative humidity can be estimated. Therefore, according to the present modification, switching from the startup operation to the normal operation can be performed at an appropriate timing using the timer.

  As described above, the present invention is useful for a humidity control apparatus that adjusts the humidity of air.
