- FIG. 7 (b) shows a wet air diagram in the case of frost formation.
- FIG. 7B shows the case where the first heat exchanger 12a is frosted.
- the air to be dehumidified introduced from the suction port 1a of the dehumidifier 100 flows into the first heat exchanger 12a.
- the air to be dehumidified is heated by the first heat exchanger 12a functioning as a condenser, and the temperature rises (point 2-2 in FIG. 7 (a)).
- the air that has passed through the first heat exchanger 12 a flows into the moisture adsorption member 20.
- the relative humidity of the air heated by the first heat exchanger 12a is lower than the relative humidity of the air at the time of introduction, the adsorbent of the moisture adsorbing member 20 can easily desorb moisture.
- the air to be dehumidified introduced from the suction port 1a of the dehumidifier 100 flows into the first heat exchanger 12a.
- the first heat exchanger 12a is frosted, and in the second operation mode, it is defrosted by the first heat exchanger 12a that functions as a condenser.
- the relative humidity of the air passing through the first heat exchanger 12a is increased by defrosting (FIG. 7B, point 2-2a) and flows into the moisture adsorbing member 20.
- the temperature of the air at this time varies depending on the temperature and humidity of the introduced air and the defrosting situation.
- the adsorbent of the moisture adsorbing member 20 is less likely to desorb moisture than when no frost is formed. Therefore, the air passing through the moisture adsorbing member 20 flows into the second heat exchanger 12b with little humidification (point of FIG. 7 (b), 2-3a). The adsorption / desorption reaction changes with the passage of time for defrosting. Since the second heat exchanger 12b functions as an evaporator, the air passing through the second heat exchanger 12b is cooled to a dew point temperature or less and dehumidified air from which moisture has been dehumidified (FIG. 7B, 2- 4a).
- the refrigerant flow path (operation mode) is switched by the flow path switch 14, It is possible to defrost using the heat of condensation. Thereby, it becomes unnecessary to provide a heater for defrosting or to stop the compressor 11 for defrosting, and it becomes possible to reduce power consumption and defrosting time.
- the second operation mode dehumidification by the moisture adsorbing member 20 is not performed, and only dehumidification by the second heat exchanger 12b is performed. Therefore, in the present embodiment, the third heat exchanger 12c is provided to suppress the heat of condensation in the first heat exchanger 12a. This makes it possible to reduce the amount of moisture that cannot be captured by the second heat exchanger 12b.
- the dehumidifying apparatus 100 performs dehumidification of the air in the dehumidifying target space by alternately switching the first operation mode and the second operation mode.
- the timing for switching between the first operation mode and the second operation mode is determined based on the operation time map 65 stored in the storage unit 6.
- FIG. 8 is a diagram for explaining the operation time map 65.
- the operation time map 65 includes a time for operating in the first operation mode (hereinafter referred to as “adsorption time”) and a time for operating in the second operation mode (hereinafter referred to as “desorption time”) for each temperature and humidity of the dehumidification target air. Are mapped in advance. In the example of FIG.
- the temperature and humidity of the dehumidification target air is divided into nine areas A to I, and the adsorption time and the desorption time are set in each of the areas A to I.
- the dehumidification amount in the first operation mode is the sum of the dew condensation amount in the first heat exchanger 12a and the moisture adsorption amount in the moisture adsorption member 20, whereas in the second operation mode.
- the dehumidification amount is only the dew condensation amount in the second heat exchanger 12b, and generally the dehumidification amount is larger in the first operation mode. Therefore, the adsorption time is set longer than the desorption time.
- the setting of the adsorption time and desorption time in the operation time map 65 will be described in detail.
- the optimum adsorption time and desorption time in the region E are obtained in advance by experiments or the like based on the temperature and humidity in the region E in FIG. 60 minutes, desorption time 15 minutes).
- standard is set as the adsorption
- the dehumidifying apparatus 100 switching from adsorption (first operation mode) to desorption (second operation mode) is performed before the moisture adsorbing member 20 is saturated and immediately before the adsorption speed decreases.
- the capacity of the moisture adsorbing member 20 can be maximized.
- the time for which the moisture adsorbing member 20 is saturated is determined by the temperature and humidity of the dehumidifying space. For example, when the relative humidity of the dehumidifying space is high and the amount of moisture in the air is large, the amount of moisture that reaches the moisture adsorbing member 20 is large and the time until saturation is reached is shortened.
- the adsorption time is set short when the relative humidity in the dehumidifying space is high, and the adsorption time is set long when the relative humidity is low.
- an adsorption time shorter than that of the region E is set in the region D having a higher humidity than the region E.
- an adsorption time longer than that of the region E is set in the region F of lower humidity than the region E.
- the adsorption time is set short when the temperature is high, and the adsorption time is set long when the temperature is low.
- an adsorption time shorter than that of the region E is set in the region H having a higher temperature than the region E.
- an adsorption time longer than that of the region E is set in the region B having a temperature lower than that of the region E.
- the time required for desorption of the moisture adsorbing member 20 also varies depending on the temperature and humidity of the dehumidifying space. After the desorption from the moisture adsorbing member 20 is completed, the amount of condensation in the second heat exchanger 12b is smaller than before the desorption. Therefore, in the second operation mode, the efficiency is improved by switching to the first operation mode at the same time as the desorption of the moisture adsorbing member 20 is completed. Desorption takes time to complete when the relative humidity of the dehumidifying space is high and the amount of moisture in the air is large, and is completed quickly when the relative humidity of the dehumidifying space is low and the amount of moisture in the air is small.
- the desorption time is set to be long when the relative humidity in the dehumidifying space is high, and the desorption time is set to be short when the relative humidity is low.
- a longer desorption time than that of the region E is set in the region D of higher humidity than the region E.
- a desorption time shorter than that of the region E is set in the region F of lower humidity than the region E.
- the desorption time is set short when the temperature is high, and the desorption time is set long when the temperature is low.
- a shorter desorption time than the region E is set in the region H having a higher temperature than the region E.
- a desorption time longer than that of the region E is set in the region B having a temperature lower than that of the region E.
- FIG. 9 is a flowchart of the operation mode switching process using the operation time map 65. This process is executed by the control means 4 when the operation of the dehumidifying device 100 is started.
- the flow path switch 14 is controlled so as to operate in the first operation mode (S1).
- the temperature and humidity of the dehumidifying space is acquired from the temperature and humidity sensor 2 (S2), and it is determined whether or not a predetermined time has passed (S3).
- the passage of the predetermined time is determined based on the time measured by the time measuring means 5.
- the temperature and humidity of the dehumidifying space often fluctuates due to opening and closing of the door of the dehumidifying space. Even if the door is not opened and closed, the temperature and humidity of the air blown from the dehumidifying device 100 change in the first operation mode and the second operation mode, and the temperature and humidity of the entire dehumidification space also change. Here, since the operation in the same mode is longer in the first operation mode than in the second operation mode, the temperature and humidity in the dehumidification space are stabilized.
- adsorption time and desorption time from the operation time map 65 using the average value of the temperature and humidity obtained at the predetermined time in the first operation mode, the influence of fluctuation is suppressed, and the optimum adsorption time and Desorption time can be acquired.
- temperature / humidity at the start of operation may be used instead of the average value of temperature / humidity at a predetermined time.
- the operation in the first operation mode is performed (S5).
- the air passage 1 may be blocked by frost formation, the air volume may be reduced, and the dehumidifying capacity may be insufficient. . Therefore, when there is frost formation, it is desirable to switch the operation mode regardless of the adsorption time acquired in the operation time map 65.
- it is determined that the wind speed detected by the wind speed sensor 3 has decreased below the reference value it is determined that the first heat exchanger 12a is frosted.
- the flow path switch 14 is controlled to perform the second operation.
- the mode is switched (S8).
- the second heat exchanger 12b is frosted (S9).
- the wind speed detected by the wind speed sensor 3 falls below the reference value, it is determined that the second heat exchanger 12b is frosted.
- the second heat exchanger 12b is not frosted (S9: NO)
- the passage of the desorption time is determined based on the time measured by the time measuring means 5.
- the process returns to S8 and the operation in the second operation mode is continued.
- the flow path switch 14 is controlled to perform the first operation.
- the mode is switched (S5).
- the air path 1 is linearized to form a rotor shape.
- the pressure loss when air is conveyed can be reduced.
- the power consumption of the air blower 30 which conveys air can be reduced, and it can be set as a more efficient apparatus.
- the moisture adsorption member 20 is placed between the first heat exchanger 12a and the second heat exchanger 12b, and adsorption and desorption are performed by switching the operation mode by the flow path switch 14. As a result, a member for rotationally driving the moisture adsorbing member 20 becomes unnecessary, and the apparatus can be reduced in size and cost.
- the first operation mode and the second operation mode can be obtained at a more appropriate timing according to the dehumidification target air. Can be switched. Thereby, it becomes possible to operate the dehumidification apparatus 100 efficiently.
- Embodiment 2 Next, the dehumidifying device 100 in Embodiment 2 of this invention is demonstrated.

- Other configurations of the dehumidifying apparatus 100 and operation mode switching processing are the same as those in the first embodiment.
- the wind speed may change depending on the location where the dehumidifying device 100 is installed.
- the operation time map 65 is created assuming a wind speed of 200V.
- the voltage is about 180V to 220V.
- a wind speed and an air volume become large with respect to 200V.
- a duct may be connected to at least one of the suction inlet 1a and the blower outlet 1b of the dehumidification apparatus 100 in the field. In this case, the amount of air passing through the air path 1 is reduced. Therefore, in the present embodiment, the operation time map 65 can be changed according to the site where the dehumidifying device 100 is installed.
- FIG. 10 is a flowchart showing map change processing in the present embodiment. This process is executed by the control means 4 before the operation mode switching process of FIG. In this process, the driving time map 65 is changed according to the wind speed detected by the wind speed sensor 3. First, the flow path switch 14 is controlled to operate in the first operation mode (S11). Then, the wind speed is acquired from the wind speed sensor 3 (S12), and the acquired wind speed is compared with the reference range (S13).
- the reference range in this case is a range in which a predetermined width is given to the wind speed assumed when the operation time map 65 is created.
- the operation time map 65 is changed (S14).
- the wind speed (air volume) passing through the moisture adsorption member 20 is small, the saturation time and the desorption time in the moisture adsorption member 20 become long. Therefore, when the wind speed is smaller than the reference range, both the adsorption time and the desorption time set in the operation time map 65 are changed longer. Then, the operation mode switching process of FIG. 9 is executed by the changed operation time map 65 (S16).
- the operation time map 65 is changed (S15).
- the wind speed (air volume) passing through the moisture adsorption member 20 is large, the saturation time and the desorption time in the moisture adsorption member 20 are shortened. Therefore, when the wind speed is larger than the reference range, both the adsorption time and the desorption time set in the operation time map 65 are changed short. Then, the operation mode switching process of FIG. 9 is executed by the changed operation time map 65 (S16).
- the adsorption time and the desorption time can be set according to the actual operation status by changing the operation time map 65 according to the situation at the site. Thereby, it becomes possible to operate the dehumidification apparatus 100 efficiently irrespective of the condition of the field.
- FIG. 11 is a schematic configuration diagram of the dehumidifying apparatus 100 according to the third embodiment.
- the dehumidifying device 100 according to the present embodiment is different from the first embodiment in that the third heat exchanger 12c is not provided.
- Other configurations of the dehumidifying apparatus 100 and operation mode switching processing are the same as those in the first embodiment.
- the refrigerant flows from the compressor 11 into the flow path switch 14, and thereafter flows through the refrigerant circulation path corresponding to the operation mode, as in the first embodiment.
- the dehumidifying apparatus 100 can be operated efficiently by switching between the first operation mode and the second operation mode at an appropriate timing according to the dehumidification target air. It becomes possible.

- both dehumidification by the heat exchanger first heat exchanger 12 a or second heat exchanger 12 b
- dehumidification by the moisture adsorption member 20 are performed.
- the contribution rate of the dehumidification amount by the moisture adsorbing member 20 to the entire dehumidification amount differs.
- a model in which the amount of dehumidification by the moisture adsorbing member 20 is larger than that of a standard model a large amount of moisture adsorption can be secured, and therefore it is preferable to set the adsorption time and desorption time to be long in advance.
- the amount of dehumidification by the moisture adsorbing member 20 is less than the standard model, the moisture adsorption amount can be secured only a little.
- the operation time map 65 is provided for each model, and the dehumidifying operation can be performed more efficiently by selecting and using the map according to the model.
- the configuration for switching between the first operation mode and the second operation mode has been described, but the present invention is not limited to this.
- the air is high temperature and high humidity, dehumidification by the refrigerant circuit 10 is dominant, and when the air is low temperature and low humidity, dehumidification by the moisture adsorbing member 20 is dominant. Therefore, when the temperature detected by the temperature / humidity sensor 2 is high temperature and high humidity, the first operation mode may be continued. Specifically, when the temperature / humidity detected by the temperature / humidity sensor 2 is the region G in FIG. 8, the adsorption time is set to the maximum operation time of the dehumidifier 100 and the operation is performed only in the first operation mode. It is also good.
- the stable air can be provided to dehumidification space, without switching the refrigerant flow path of the refrigerant circuit 10.
- FIG. Furthermore, the switching frequency of the flow path switching device 14 can be reduced, the failure accompanying the increase in the number of opening and closing operations can be suppressed, and the highly reliable dehumidifying device 100 can be provided.

Description
図1は本発明の実施の形態1における除湿装置100の概略構成図である。図1に示すように、除湿装置100は、筐体(図示せず)内に収容される、圧縮機11、第1の熱交換器12a、第2の熱交換器12b、第3の熱交換器12c、減圧装置13および流路切替器14が冷媒配管で接続された冷媒回路10と、水分吸着部材20と、送風機30とを備える。また、除湿装置100の筐体内には、除湿対象空間からの空気を取り込む吸込口1aと除湿対象空間へ空気を放出する吹出口1bとをつなぐ風路1が形成される。風路1には、吸込口1aから順に、第1の熱交換器12a、水分吸着部材20、第2の熱交換器12b、第3の熱交換器12cおよび送風機30が配置される。
まず、図4を参照して第1の運転モードでの冷媒回路10の冷媒動作を説明する。第1の運転モードでは、図4に示す実線に沿って冷媒が流れる。詳しくは、圧縮機11によって圧縮され、吐出された冷媒は第3の熱交換器12cに流入する。第3の熱交換器12cは凝縮器として機能し、冷媒は空気と熱交換して一部が凝縮液化する。第3の熱交換器12cを通過した冷媒は、流路切替器14を通って第2の熱交換器12bに流入する。第2の熱交換器12bは凝縮器として機能し、冷媒は空気と熱交換して凝縮液化する。第2の熱交換器12bを通過した冷媒は、減圧装置13に流入し、減圧装置13で減圧された後、第1の熱交換器12aに流入する。第1の熱交換器12aは、蒸発器として機能し、冷媒は空気と熱交換して蒸発する。第1の熱交換器12aを通過した冷媒は、流路切替器14を通って再び圧縮機11に吸入される。
次に図5を参照して第1の運転モードでの除湿装置100の風路1内における空気の動作を説明する。第1の運転モードでは、まず、除湿装置100の吸込口1aから導入された除湿対象空気(図5、1-1点)が第1の熱交換器12aに流入する。ここで、除湿対象空気は、蒸発器として機能する第1の熱交換器12aによって露点温度以下に冷却され、水分が除湿された除湿空気となる(図5、1-2点)。第1の熱交換器12aによって冷却除湿された空気は、水分吸着部材20に流入する。ここで、冷却除湿された空気の相対湿度は80~90(%RH)程度と高くなっているため、水分吸着部材20の吸着剤は水分を吸着しやすくなる。水分吸着部材20の吸着剤により水分が吸着(除湿)され、低湿化された空気(図5、1-3点)は、第2の熱交換器12bに流入する。第2の熱交換器12bは凝縮器として機能しているため、通過する空気は加熱され、温度が上昇する(図5、1-4点)。第2の熱交換器12bを通過した空気は、第3の熱交換器12cに流入する。第3の熱交換器12cは凝縮器として機能しているため、通過する空気は加熱され、温度が上昇する(図5、1-5点)。第3の熱交換器12cを通過した空気は、吹出口1bより放出される。
次に、図6を参照して第2の運転モードでの冷媒回路10の冷媒動作を説明する。第2の運転モードでは、図6に示す実線に沿って冷媒が流れる。詳しくは、圧縮機11によって圧縮され、吐出された冷媒は第3の熱交換器12cに流入する。第3の熱交換器12cは凝縮器として機能し、冷媒は空気と熱交換して一部が凝縮液化する。第3の熱交換器12cを通過した冷媒は、流路切替器14を通って第1の熱交換器12aに流入する。第1の熱交換器12aは凝縮器として機能し、冷媒は空気と熱交換して凝縮液化する。第1の熱交換器12aを通過した冷媒は、減圧装置13に流入し、減圧装置13で減圧された後、第2の熱交換器12bに流入する。第2の熱交換器12bは、蒸発器として機能し、冷媒は空気と熱交換して蒸発する。第2の熱交換器12bを通過した冷媒は、流路切替器14を通って再び圧縮機11に吸入される。
次に、図7を参照して第2の運転モードでの除湿装置100の風路1内における空気の動作を説明する。なお、第2の運転モードにおいては、第1の熱交換器12aまたは第2の熱交換器12bに着霜しているか否かによって空気の動作が異なる。そのため、着霜無しの場合の湿り空気線図を図7(a)に示し、着霜ありの場合の湿り空気線図を図7(b)に示す。なお、図7(b)の例では、第1の熱交換器12aに着霜した場合について説明する。
次に本発明の実施の形態2における除湿装置100について説明する。実施の形態2の除湿装置100は、運転モード切り替え処理に先立って、運転時間マップ65を変更する点において、実施の形態1と相違する。その他の除湿装置100の構成および運転モード切り替え処理は実施の形態1と同様である。
次に本発明の実施の形態3における除湿装置100について説明する。図11は、実施の形態3の除湿装置100の概略構成図である。本実施の形態における除湿装置100は、第3の熱交換器12cを備えていない点において、実施の形態1と相違する。その他の除湿装置100の構成および運転モード切り替え処理は実施の形態1と同様である。本実施形態において、冷媒は、圧縮機11から流路切替器14に流入し、その後は実施の形態1と同様に、運転モードに応じた冷媒循環経路を流れる。本実施の形態においても、実施の形態1と同様に、除湿対象空気に応じた適切なタイミングで第1の運転モードと第2の運転モードとを切り替え、除湿装置100を効率良く動作させることが可能となる。
