Abstract
Description
本発明は、吸着剤を用いて空気の湿度を調節する調湿装置に関するものである。 The present invention relates to a humidity control apparatus that adjusts the humidity of air using an adsorbent.
従来より、吸着剤を利用して空気の湿度調節を行う調湿装置が知られている。特許文献１には、表面に吸着剤が担持された吸着熱交換器を備えた調湿装置が開示されている。この調湿装置は、いわゆるバッチ式の動作を行う。 Conventionally, a humidity control apparatus that adjusts the humidity of air using an adsorbent is known. Patent Document 1 discloses a humidity control apparatus including an adsorption heat exchanger having an adsorbent supported on its surface. This humidity control apparatus performs a so-called batch operation.
具体的に、特許文献１に開示された調湿装置には、２つの吸着熱交換器を備えた冷媒回路が設けられている。この冷媒回路は、第１の吸着熱交換器が凝縮器となって第２の吸着熱交換器が蒸発器となる第１動作と、第２の吸着熱交換器が凝縮器となって第１の吸着熱交換器が蒸発器となる第２動作とを、所定の時間間隔で交互に行う。蒸発器として動作する吸着熱交換器では、吸着剤に空気中の水分が吸着される。凝縮器として動作する吸着熱交換器では、水分が吸着剤から脱離して空気に付与される。 Specifically, the humidity control device disclosed in Patent Document 1 is provided with a refrigerant circuit including two adsorption heat exchangers. The refrigerant circuit includes a first operation in which the first adsorption heat exchanger serves as a condenser and the second adsorption heat exchanger serves as an evaporator, and the second adsorption heat exchanger serves as a condenser. The second operation in which the adsorption heat exchanger becomes an evaporator is alternately performed at predetermined time intervals. In the adsorption heat exchanger operating as an evaporator, moisture in the air is adsorbed by the adsorbent. In an adsorption heat exchanger that operates as a condenser, moisture is desorbed from the adsorbent and applied to the air.
特許文献１に開示された調湿装置は、各吸着熱交換器を通過した空気の一方を室内へ供給して他方を室外へ排出する。除湿運転中の調湿装置では、第１及び第２の吸着熱交換器のうち蒸発器として動作する方を通過した空気が室内へ供給されて凝縮器として動作する方を通過した空気が室外へ排出される。また、加湿運転中の調湿装置では、第１及び第２の吸着熱交換器のうち蒸発器として動作する方を通過した空気が室外へ排出されて凝縮器として動作する方を通過した空気が室内へ供給される。
除湿運転中や加湿運転中の調湿装置では、吸着熱交換器に空気中の水分が吸着されてゆく。その際には、吸着剤を担持する吸着熱交換器が実質的な飽和状態となった時点で第１動作と第２動作の相互切り換えを行えば、調湿装置の調湿能力が最大限に発揮されるので望ましい。 In the humidity control apparatus during the dehumidifying operation or the humidifying operation, moisture in the air is adsorbed by the adsorption heat exchanger. At that time, if the adsorption heat exchanger carrying the adsorbent is substantially saturated, the humidity control capacity of the humidity control device can be maximized by switching between the first operation and the second operation. It is desirable because it is demonstrated.
一方、調湿装置に除湿運転が求められる場合は、調湿装置に加湿運転が求められる場合に比べ、室内外の空気の湿度が高くなるのが通常である。つまり、除湿運転中には、加湿運転中に比べて、吸着熱交換器が実質的な飽和状態に達するまでに要する時間が短くなる。 On the other hand, when the dehumidifying operation is required for the humidity control device, the humidity of the indoor and outdoor air is usually higher than when the humidifying operation is required for the humidity control device. That is, during the dehumidifying operation, the time required for the adsorption heat exchanger to reach a substantially saturated state is shorter than during the humidifying operation.
このため、例えば第１動作と第２動作の切り換え時間間隔が、加湿運転中に吸着熱交換器が実質的な飽和状態に達した時点で動作が切り換わるような値に設定されていると、除湿運転中には、吸着熱交換器が実質的な飽和状態に達してからある程度の時間が経過した後でなければ動作が切り換わらないことになる。また、第１動作と第２動作の切り換え時間間隔が、除湿運転中に吸着熱交換器が実質的な飽和状態に達した時点で動作が切り換わるような値に設定されていると、加湿運転中には、吸着熱交換器が実質的な飽和状態に達する前に動作が切り換わってしまうことになる。従って、第１動作と第２動作の切り換え時間間隔が除湿運転中と加湿運転中とで同じ値に設定されていると、除湿運転と加湿運転の一方でしか調湿装置の能力を充分に発揮させることができない。 For this reason, for example, when the switching time interval between the first operation and the second operation is set to such a value that the operation is switched when the adsorption heat exchanger reaches a substantially saturated state during the humidification operation, During the dehumidifying operation, the operation is not switched until a certain time has elapsed after the adsorption heat exchanger reaches a substantially saturated state. In addition, if the switching time interval between the first operation and the second operation is set to a value such that the operation is switched when the adsorption heat exchanger reaches a substantially saturated state during the dehumidifying operation, the humidifying operation is performed. In some cases, the operation switches before the adsorption heat exchanger reaches substantial saturation. Therefore, if the switching time interval between the first operation and the second operation is set to the same value during the dehumidifying operation and during the humidifying operation, the ability of the humidity control apparatus can be sufficiently exerted only in either the dehumidifying operation or the humidifying operation. I can't let you.
本発明は、かかる点に鑑みてなされたものであり、その目的は、いわゆるバッチ式の動作を行う調湿装置において、除湿運転と加湿運転の両方で調湿装置の調湿能力を充分に発揮させることにある。 The present invention has been made in view of the above points, and its purpose is to fully demonstrate the humidity control capability of the humidity control apparatus in both the dehumidifying operation and the humidifying operation in a humidity control apparatus that performs so-called batch operation. There is to make it.
第１の発明は、それぞれが吸着剤を有して該吸着剤を空気と接触させる第１及び第２の吸着ユニット（51,52,111,112）を備え、第１の吸着ユニット（51,111）で吸着剤を再生して第２空気を加湿すると同時に第２の吸着ユニット（52,112）で第１空気を除湿する第１動作と、第２の吸着ユニット（52,112）で吸着剤を再生して第２空気を加湿すると同時に第１の吸着ユニット（51,111）で第１空気を除湿する第２動作とを所定の切換時間間隔で交互に繰り返し、除湿された第１空気を室内へ供給する除湿運転と、加湿された第２空気を室内へ供給する加湿運転とを選択的に行う調湿装置を対象とする。そして、除湿運転中における上記切換時間間隔が、加湿運転中における上記切換時間間隔よりも短くなっているものである。 The first invention includes first and second adsorption units (51, 52, 111, 112) each having an adsorbent and contacting the adsorbent with air, and the adsorbent is provided by the first adsorption unit (51, 111). Regenerating and humidifying the second air, and simultaneously dehumidifying the first air with the second adsorption unit (52, 112), and regenerating the adsorbent with the second adsorption unit (52, 112) to humidify the second air At the same time, the second operation of dehumidifying the first air by the first adsorption unit (51, 111) is alternately repeated at a predetermined switching time interval, and the dehumidifying operation for supplying the dehumidified first air to the room and the humidification are performed. A humidity control apparatus that selectively performs a humidifying operation for supplying the second air into the room is intended. The switching time interval during the dehumidifying operation is shorter than the switching time interval during the humidifying operation.
第１の発明の調湿装置（10）では、除湿運転と加湿運転が選択的に行われる。除湿運転中および加湿運転中の調湿装置（10）は、第１動作と第２動作とを相互に繰り返し行う。第１動作中の調湿装置（10）では、第１の吸着ユニット（51,111）へ第２空気が送られ、第２の吸着ユニット（52,112）へ第１空気が送られる。第１の吸着ユニット（51,111）では、吸着剤の再生が行われ、吸着剤から脱離した水分が第２空気に付与される。第２の吸着ユニット（52,112）では、第１空気中の水分が吸着剤に吸着される。一方、第２動作中の調湿装置（10）では、第１の吸着ユニット（51,111）へ第１空気が送られ、第２の吸着ユニット（52,112）へ第２空気が送られる。第１の吸着ユニット（51,111）では、第１空気中の水分が吸着剤に吸着される。第２の吸着ユニット（52,112）では、吸着剤の再生が行われ、吸着剤から脱離した水分が第２空気に付与される。そして、除湿運転中には吸着ユニット（51,52,111,112）で除湿された第１空気が室内へ供給され、加湿運転中には吸着ユニット（51,52,111,112）で加湿された第２空気が室内へ供給される。 In the humidity control apparatus (10) of the first invention, the dehumidifying operation and the humidifying operation are selectively performed. The humidity control apparatus (10) during the dehumidifying operation and the humidifying operation repeatedly performs the first operation and the second operation. In the humidity controller (10) during the first operation, the second air is sent to the first adsorption unit (51, 111), and the first air is sent to the second adsorption unit (52, 112). In the first adsorption unit (51, 111), the adsorbent is regenerated, and moisture desorbed from the adsorbent is given to the second air. In the second adsorption unit (52, 112), moisture in the first air is adsorbed by the adsorbent. On the other hand, in the humidity controller (10) in the second operation, the first air is sent to the first adsorption unit (51, 111) and the second air is sent to the second adsorption unit (52, 112). In the first adsorption unit (51, 111), moisture in the first air is adsorbed by the adsorbent. In the second adsorption unit (52, 112), the adsorbent is regenerated, and moisture desorbed from the adsorbent is given to the second air. The first air dehumidified by the adsorption unit (51, 52, 111, 112) is supplied to the room during the dehumidifying operation, and the second air humidified by the adsorption unit (51, 52, 111, 112) is supplied to the room during the humidifying operation. Is done.
第１の発明の調湿装置（10）では、第１動作と第２動作が所定の切換時間間隔で交互に実行される。また、この調湿装置（10）では、除湿運転中において第１動作と第２動作が相互に切り換わる時間間隔（即ち、切換時間間隔）が、加湿運転中において第１動作と第２動作が相互に切り換わる時間間隔（即ち、切換時間間隔）よりも短くなっている。例えば、除湿運転中には第１動作と第２動作が３分間毎に交互に実行されるとすると、加湿運転中には第１動作と第２動作が３分間よりも長い時間間隔（例えば４分間毎）で交互に実行されることになる。つまり、この調湿装置（10）において、１回の第１／第２動作の継続時間は、除湿運転中の方が加湿運転中に比べて短くなる。 In the humidity control apparatus (10) of 1st invention, 1st operation | movement and 2nd operation | movement are performed alternately by a predetermined switching time interval. In the humidity control apparatus (10), the time interval (that is, the switching time interval) at which the first operation and the second operation are switched to each other during the dehumidifying operation is different, and the first operation and the second operation are performed during the humidifying operation. It is shorter than the time interval (that is, the switching time interval) at which they switch to each other. For example, if the first operation and the second operation are alternately performed every 3 minutes during the dehumidifying operation, the first operation and the second operation are performed at a time interval longer than 3 minutes (for example, 4 minutes) during the humidifying operation. Every other minute). That is, in the humidity control apparatus (10), the duration of one first / second operation is shorter during the dehumidifying operation than during the humidifying operation.
第２の発明は、上記第１の発明において、除湿運転中には、第１空気として室外空気を、第２空気として室内空気をそれぞれ取り込み、除湿された第１空気を室内へ供給して加湿された第２空気を室外へ排出する一方、加湿運転中には、第１空気として室内空気を、第２空気として室外空気をそれぞれ取り込み、加湿された第２空気を室内へ供給して除湿された第１空気を室外へ排出するものである。 According to a second invention, in the first invention, during the dehumidifying operation, outdoor air is taken in as the first air, indoor air is taken in as the second air, and the dehumidified first air is supplied to the room and humidified. While the second air thus discharged is discharged to the outside, during the humidifying operation, the indoor air is taken in as the first air and the outdoor air is taken in as the second air, and the humidified second air is supplied into the room to be dehumidified. The first air is discharged outside the room.
第２の発明では、調湿装置（10）によって室内の換気が行われる。つまり、除湿運転中の調湿装置（10）は、第１空気として取り込んだ室外空気を吸着ユニット（51,52,111,112）で除湿してから室内へ供給すると同時に、第２空気として取り込んだ室内空気を吸着ユニット（51,52,111,112）から脱離した水分と共に室外へ排出する。また、加湿運転中の調湿装置（10）は、第２空気として取り込んだ室外空気を吸着ユニット（51,52,111,112）で加湿してから室内へ供給すると同時に、第１空気として取り込んだ室内空気を吸着ユニット（51,52,111,112）で除湿してから室外へ排出する。 In the second invention, the room is ventilated by the humidity control device (10). That is, the humidity control apparatus (10) during the dehumidifying operation dehumidifies the outdoor air taken in as the first air by the adsorption unit (51, 52, 111, 112) and then supplies it to the room, and at the same time, the indoor air taken in as the second air The moisture desorbed from the adsorption unit (51, 52, 111, 112) is discharged outside the room. In addition, the humidity control device (10) during the humidifying operation humidifies the outdoor air taken in as the second air by the adsorption unit (51, 52, 111, 112) and supplies it to the room. After dehumidifying by the adsorption unit (51, 52, 111, 112), it is discharged outside the room.
第３の発明は、上記第１又は第２の発明において、表面に吸着剤が担持された吸着熱交換器（51,52）が複数接続されると共に、第１の吸着熱交換器（51）が放熱器となって第２の吸着熱交換器（52）が蒸発器となる第１の冷凍サイクル動作と、第２の吸着熱交換器（52）が放熱器となって第１の吸着熱交換器（51）が蒸発器となる第２の冷凍サイクル動作とが切換可能な冷媒回路（50）を備え、上記冷媒回路（50）では、第１動作中に第１の冷凍サイクル動作が、第２動作中に第２の冷凍サイクル動作がそれぞれ行われ、上記第１の吸着熱交換器（51）が第１の吸着ユニットを、上記第２の吸着熱交換器（52）が第２の吸着ユニットをそれぞれ構成しているものである。 According to a third invention, in the first or second invention, a plurality of adsorption heat exchangers (51, 52) each having an adsorbent supported on a surface thereof are connected, and the first adsorption heat exchanger (51) Becomes the radiator, the first refrigeration cycle operation in which the second adsorption heat exchanger (52) becomes the evaporator, and the second adsorption heat exchanger (52) becomes the radiator and the first adsorption heat. The exchanger (51) includes a refrigerant circuit (50) that can be switched to a second refrigeration cycle operation that serves as an evaporator. In the refrigerant circuit (50), the first refrigeration cycle operation is performed during the first operation. A second refrigeration cycle operation is performed during the second operation, the first adsorption heat exchanger (51) serving as the first adsorption unit, and the second adsorption heat exchanger (52) serving as the second. Each of the adsorption units is configured.
第３の発明では、吸着熱交換器（51,52）を備える冷媒回路（50）が調湿装置（10）に設けられ、この吸着熱交換器（51,52）が吸着ユニットを構成する。冷媒回路（50）は、第１動作中には第１冷凍サイクル動作を行い、第２動作中には第２冷凍サイクル動作を行う。 In 3rd invention, the refrigerant circuit (50) provided with an adsorption heat exchanger (51,52) is provided in a humidity control apparatus (10), and this adsorption heat exchanger (51,52) comprises an adsorption unit. The refrigerant circuit (50) performs the first refrigeration cycle operation during the first operation, and performs the second refrigeration cycle operation during the second operation.
この第３の発明において、第１の冷凍サイクル動作中には、放熱器となる第１の吸着熱交換器（51）へ第２空気が送られて、蒸発器となる第２の吸着熱交換器（52）へ第１空気が送られる。そして、第１の吸着熱交換器（51）では、冷媒により加熱されて吸着剤が再生され、吸着剤から脱離した水分が第２空気に付与される。また、第２の吸着熱交換器（52）では、第１空気中の水分が吸着剤に吸着され、その際に生じる吸着熱を冷媒が吸熱する。一方、第２の冷凍サイクル動作中には、蒸発器となる第１の吸着熱交換器（51）へ第１空気が送られて、放熱器となる第２の吸着熱交換器（52）へ第２空気が送られる。そして、第１の吸着熱交換器（51）では、第１空気中の水分が吸着剤に吸着され、その際に生じる吸着熱を冷媒が吸熱する。また、第２の吸着熱交換器（52）では、冷媒により加熱されて吸着剤が再生され、吸着剤から脱離した水分が第２空気に付与される。 In the third aspect of the invention, during the operation of the first refrigeration cycle, the second air is sent to the first adsorption heat exchanger (51) serving as a radiator, and the second adsorption heat exchange serving as an evaporator. The first air is sent to the vessel (52). In the first adsorption heat exchanger (51), the adsorbent is regenerated by being heated by the refrigerant, and moisture desorbed from the adsorbent is given to the second air. In the second adsorption heat exchanger (52), moisture in the first air is adsorbed by the adsorbent, and the refrigerant absorbs the heat of adsorption generated at that time. On the other hand, during the operation of the second refrigeration cycle, the first air is sent to the first adsorption heat exchanger (51) serving as an evaporator and to the second adsorption heat exchanger (52) serving as a radiator. Second air is sent. In the first adsorption heat exchanger (51), moisture in the first air is adsorbed by the adsorbent, and the refrigerant absorbs the heat of adsorption generated at that time. In the second adsorption heat exchanger (52), the adsorbent is regenerated by being heated by the refrigerant, and moisture desorbed from the adsorbent is given to the second air.
上述したように、調湿装置（10）で除湿運転が行われる場合は、調湿装置（10）で加湿運転が行われる場合に比べ、吸着ユニット（51,52,111,112）に水分を奪われる第１空気の湿度が高くなるのが通常である。つまり、除湿運転中には、加湿運転中に比べて、吸着ユニット（51,52,111,112）が実質的な飽和状態に達するまでに要する時間が短くなる。 As described above, when the dehumidifying operation is performed by the humidity control apparatus (10), the adsorption unit (51, 52, 111, 112) is deprived of moisture as compared with the case where the humidifying operation is performed by the humidity control apparatus (10). The humidity of air is usually high. That is, during the dehumidifying operation, the time required for the adsorption units (51, 52, 111, 112) to reach a substantially saturated state is shorter than during the humidifying operation.
それに対し、本発明の調湿装置（10）では、除湿運転中における第１動作と第２動作の切り換え時間間隔が、加湿運転中における第１動作と第２動作の切り換え時間間隔よりも短くなっている。つまり、第１空気の湿度が比較的低く、吸着ユニット（51,52,111,112）が実質的な飽和状態に達するまでに要する時間が比較的長い加湿運転中には、第１／第２動作の継続時間を長く設定する一方、第１空気の湿度が比較的高く、吸着ユニット（51,52,111,112）が実質的な飽和状態に達するまでに要する時間が比較的短い除湿運転中には、第１／第２動作の継続時間を短く設定している。 In contrast, in the humidity control apparatus (10) of the present invention, the switching time interval between the first operation and the second operation during the dehumidifying operation is shorter than the switching time interval between the first operation and the second operation during the humidifying operation. ing. That is, the duration of the first / second operation during the humidification operation in which the humidity of the first air is relatively low and the time required for the adsorption unit (51, 52, 111, 112) to reach a substantially saturated state is relatively long. In the dehumidifying operation, the humidity of the first air is relatively high and the time required for the adsorption units (51, 52, 111, 112) to reach a substantially saturated state is relatively short. The operation duration is set short.
従って、本発明によれば、除湿運転と加湿運転の両方において、吸着ユニット（51,52,111,112）が実質的な飽和状態に達する時点と、第１動作と第２動作の一方から他方への切り換えが行われる時点との差を短縮することができる。その結果、除湿運転と加湿運転の両方で調湿装置（10）の調湿能力を充分に発揮させることが可能となる。 Therefore, according to the present invention, when the adsorption unit (51, 52, 111, 112) reaches a substantially saturated state in both the dehumidifying operation and the humidifying operation, switching from one of the first operation and the second operation to the other is performed. It is possible to reduce the difference from the time when it is performed. As a result, it becomes possible to fully exhibit the humidity control capability of the humidity control apparatus (10) in both the dehumidifying operation and the humidifying operation.
以下、本発明の実施形態を図面に基づいて詳細に説明する。本実施形態の調湿装置（10）は、室内の湿度調節と共に室内の換気を行うものであり、取り込んだ室外空気（OA）を湿度調節して室内へ供給すると同時に、取り込んだ室内空気（RA）を室外に排出する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The humidity control device (10) of the present embodiment performs indoor ventilation as well as indoor humidity adjustment. At the same time, the taken outdoor air (OA) is humidity-adjusted and supplied to the room. ) To the outside.

In the refrigerant circuit (50) during the first operation, the four-way switching valve (54) is set to the first state (the state shown in FIG. 3A), and the first adsorption heat exchanger (51) is condensed. The second adsorption heat exchanger (52) becomes an evaporator. That is, in the refrigerant circuit (50), the first refrigeration cycle operation is performed.
外気側通路（34）へ流入して外気側フィルタ（28）を通過した第１空気は、第２外気側ダンパ（44）を通って第２熱交換器室（38）へ流入し、その後に第２吸着熱交換器（52）を通過する。第２吸着熱交換器（52）では、第１空気中の水分が吸着剤に吸着され、その際に生じた吸着熱が冷媒に吸熱される。第２吸着熱交換器（52）で除湿された第１空気は、第２給気側ダンパ（46）を通って給気側通路（31）へ流入し、給気ファン室（36）を通過後に給気口（22）を通って室内へ供給される。 The first air that has flowed into the outside air passage (34) and passed through the outside air filter (28) flows into the second heat exchanger chamber (38) through the second outside air damper (44), and thereafter It passes through the second adsorption heat exchanger (52). In the second adsorption heat exchanger (52), moisture in the first air is adsorbed by the adsorbent, and the heat of adsorption generated at that time is absorbed by the refrigerant. The first air dehumidified by the second adsorption heat exchanger (52) flows into the supply air passage (31) through the second supply air damper (46) and passes through the supply air fan chamber (36).

In the first adsorption heat exchanger (51), moisture is desorbed from the adsorbent heated by the refrigerant, and the desorbed moisture is given to the second air. The second air given moisture in the first adsorption heat exchanger (51) flows into the exhaust side passage (33) through the first exhaust side damper (47) and passes through the exhaust fan chamber (35).

外気側通路（34）へ流入して外気側フィルタ（28）を通過した第１空気は、第１外気側ダンパ（43）を通って第１熱交換器室（37）へ流入し、その後に第１吸着熱交換器（51）を通過する。第１吸着熱交換器（51）では、第１空気中の水分が吸着剤に吸着され、その際に生じた吸着熱が冷媒に吸熱される。第１吸着熱交換器（51）で除湿された第１空気は、第１給気側ダンパ（45）を通って給気側通路（31）へ流入し、給気ファン室（36）を通過後に給気口（22）を通って室内へ供給される。 The first air that has flowed into the outside air passage (34) and passed through the outside air filter (28) flows into the first heat exchanger chamber (37) through the first outside air damper (43), and thereafter Passes through the first adsorption heat exchanger (51). In the first adsorption heat exchanger (51), moisture in the first air is adsorbed by the adsorbent, and the adsorption heat generated at that time is absorbed by the refrigerant. The first air dehumidified by the first adsorption heat exchanger (51) flows into the supply air passage (31) through the first supply air damper (45) and passes through the supply air fan chamber (36). Later, the air is supplied into the room through the air supply port (22).
一方、内気側通路（32）へ流入して内気側フィルタ（27）を通過した第２空気は、第２内気側ダンパ（42）を通って第２熱交換器室（38）へ流入し、その後に第２吸着熱交換器（52）を通過する。第２吸着熱交換器（52）では、冷媒で加熱された吸着剤から水分が脱離し、この脱離した水分が第２空気に付与される。第２吸着熱交換器（52）で水分を付与された第２空気は、第２排気側ダンパ（48）を通って排気側通路（33）へ流入し、排気ファン室（35）を通過後に排気口（21）を通って室外へ排出される。 On the other hand, the second air that has flowed into the room air passage (32) and passed through the room air filter (27) flows into the second heat exchanger chamber (38) through the second room air damper (42), Thereafter, it passes through the second adsorption heat exchanger (52). In the second adsorption heat exchanger (52), moisture is desorbed from the adsorbent heated by the refrigerant, and the desorbed moisture is given to the second air. The second air given moisture in the second adsorption heat exchanger (52) flows into the exhaust side passage (33) through the second exhaust side damper (48) and passes through the exhaust fan chamber (35). It is discharged outside through the exhaust port (21).

As shown in FIG. 7, during the second operation, the first inside air damper (41), the second outside air damper (44), the second air supply damper (46), and the first exhaust damper ( 47) is opened, and the second inside air damper (42), the first outside air damper (43), the first air supply side damper (45), and the second exhaust side damper (48) are closed. In the refrigerant circuit (50) during the second operation, the four-way switching valve (54) is set to the second state (the state shown in FIG. 3B), and the first adsorption heat exchanger (51) is evaporated.

<Simple ventilation operation>
The operation of the humidity control apparatus (10) during the simple ventilation operation will be described with reference to FIG.
単純換気運転中の調湿装置（10）では、第１バイパス用ダンパ（83）及び第２バイパス用ダンパ（84）が開状態となり、第１内気側ダンパ（41）、第２内気側ダンパ（42）、第１外気側ダンパ（43）、第２外気側ダンパ（44）、第１給気側ダンパ（45）、第２給気側ダンパ（46）、第１排気側ダンパ（47）、及び第２排気側ダンパ（48）が閉状態となる。また、単純換気運転中において、冷媒回路（50）の圧縮機（53）は停止状態となる。 In the humidity control apparatus (10) during the simple ventilation operation, the first bypass damper (83) and the second bypass damper (84) are opened, and the first room air damper (41) and the second room air damper ( 42), a first external air damper (43), a second external air damper (44), a first air supply damper (45), a second air supply damper (46), a first exhaust air damper (47), And the 2nd exhaust side damper (48) will be in a closed state.

−コントローラの制御動作−
コントローラ（60）が行う制御動作について説明する。
-Controller control action-
The control operation performed by the controller (60) will be described.
上述したように、コントローラ（60）は、除湿換気運転中や加湿換気運転中に各ダンパ（41〜48）や四方切換弁（54）の動作を制御することによって、第１動作と第２動作の切り換えを行う。コントローラ（60）は、除湿換気運転中には３分間毎に第１動作と第２動作を相互に切り換える一方、加湿換気運転中には４分間毎に第１動作と第２動作を相互に切り換える。 As described above, the controller (60) controls the operations of the dampers (41 to 48) and the four-way switching valve (54) during the dehumidification / ventilation operation and the humidification / ventilation operation, so that the first operation and the second operation are performed. Switch. The controller (60) switches between the first operation and the second operation every 3 minutes during the dehumidification ventilation operation, and switches between the first operation and the second operation every 4 minutes during the humidification ventilation operation. .
このように、本実施形態のコントローラ（60）において、第１動作と第２動作の切り換え時間間隔は、除湿換気運転中の方が加湿換気運転中に比べて短い時間に設定されている。その理由について説明する。 Thus, in the controller (60) of the present embodiment, the switching time interval between the first operation and the second operation is set to a shorter time during the dehumidification ventilation operation than during the humidification ventilation operation. The reason will be described.
除湿換気運転中の調湿装置（10）では、第１空気としてケーシング（11）内に取り込まれた室外空気が、蒸発器として動作している吸着熱交換器（51,52）へ送られる。一方、加湿湿換気運転中の調湿装置（10）では、第１空気としてケーシング（11）内に取り込まれた室内空気が、蒸発器として動作している吸着熱交換器（51,52）へ送られる。 In the humidity control apparatus (10) in the dehumidification / ventilation operation, outdoor air taken into the casing (11) as the first air is sent to the adsorption heat exchanger (51, 52) operating as an evaporator. On the other hand, in the humidity control apparatus (10) during the humidifying and humidifying operation, the indoor air taken into the casing (11) as the first air is transferred to the adsorption heat exchanger (51, 52) operating as an evaporator. Sent.
除湿換気運転が行われるのは、夏季等の室内の冷房が行われる期間（いわゆる冷房シーズン）であるのが一般的であり、加湿換気運転が行われるのは、冬季等の室内の暖房が行われる期間（いわゆる暖房シーズン）であるのが一般的である。そして、通常であれば、冷房シーズンにおける室外空気の温度と相対湿度は、暖房シーズンにおける室内空気の温度と相対湿度に比べて高くなる。つまり、蒸発器として動作している吸着熱交換器（51,52）へ第１空気として送られる空気の相対湿度は、除湿換気運転中の方が加湿換気運転中に比べて高くなるのが通常である。 The dehumidification ventilation operation is generally performed during the indoor cooling period (so-called cooling season) such as in summer, and the humidification ventilation operation is performed during indoor heating in the winter season. It is common for this period (the so-called heating season). And normally, the temperature and relative humidity of the outdoor air in the cooling season are higher than the temperature and relative humidity of the indoor air in the heating season. In other words, the relative humidity of the air sent as the first air to the adsorption heat exchanger (51, 52) operating as an evaporator is usually higher during dehumidification ventilation operation than during humidification ventilation operation. It is.
一方、単位時間当たりに吸着熱交換器（51,52）へ吸着される水分の量は、吸着熱交換器（51,52）へ送られる空気の相対湿度が高いほど多くなる。このため、第１動作や第２動作が開始された時点から、吸着熱交換器（51,52）に吸着された水分の量がある程度大きな値に達するまでに要する時間は、除湿換気運転中の方が加湿換気運転中に比べて短くなる。 On the other hand, the amount of moisture adsorbed to the adsorption heat exchanger (51, 52) per unit time increases as the relative humidity of the air sent to the adsorption heat exchanger (51, 52) increases. For this reason, the time required for the amount of water adsorbed by the adsorption heat exchanger (51, 52) to reach a certain large value from the time when the first operation or the second operation is started is the same as that during the dehumidification ventilation operation. Is shorter than during humidified ventilation operation.
また、単位時間当たりに吸着熱交換器（51,52）へ吸着される水分の量は、吸着熱交換器（51,52）における水分の吸着量が増えるにつれて減少してゆく。このため、吸着熱交換器（51,52）に吸着された水分の量がある程度大きな値に達すると、その後に吸着熱交換器（51,52）へ空気を供給し続けても、吸着熱交換器（51,52）における水分の吸着量は殆ど増えてゆかなくなる。つまり、吸着熱交換器（51,52）は、実質的な飽和状態となる。そこで、本実施形態のコントローラ（60）では、第１動作と第２動作の切り換え時間間隔が、加湿換気運転中に比べて除湿換気運転中の方が短い時間に設定されている。 In addition, the amount of moisture adsorbed to the adsorption heat exchanger (51, 52) per unit time decreases as the amount of moisture adsorption in the adsorption heat exchanger (51, 52) increases. For this reason, if the amount of moisture adsorbed on the adsorption heat exchanger (51, 52) reaches a certain value, the adsorption heat exchange will continue even if air is continuously supplied to the adsorption heat exchanger (51, 52). The amount of moisture adsorbed in the vessel (51, 52) hardly increases. That is, the adsorption heat exchanger (51, 52) is substantially saturated. Therefore, in the controller (60) of the present embodiment, the switching time interval between the first operation and the second operation is set to a shorter time during the dehumidifying ventilation operation than during the humidifying ventilation operation.
なお、本実施形態のコントローラ（60）では、除湿換気運転中における第１動作と第２動作の切り換え時間間隔が３分間に設定され、加湿換気運転中における第１動作と第２動作の切り換え時間間隔が４分間に設定されているが、これらの値は単なる一例である。
つまり、第１動作と第２動作の切り換え時間間隔は、例えば吸着熱交換器（51,52）の大きさや吸着剤の性能等に応じて適宜設定されるものである。ただし、除湿換気運転中における第１動作と第２動作の切り換え時間間隔は、加湿換気運転中における第１動作と第２動作の切り換え時間間隔の６０％以上９０％以下の範囲の値に設定されるのが望ましく、その７０％以上８０％以下の範囲の値に設定されるのが更に望ましい。
In the controller (60) of the present embodiment, the switching time interval between the first operation and the second operation during the dehumidification ventilation operation is set to 3 minutes, and the switching time between the first operation and the second operation during the humidification ventilation operation is set. Although the interval is set to 4 minutes, these values are merely examples.
That is, the switching time interval between the first operation and the second operation is appropriately set according to the size of the adsorption heat exchanger (51, 52), the performance of the adsorbent, and the like. However, the switching time interval between the first operation and the second operation during the dehumidifying ventilation operation is set to a value in the range of 60% to 90% of the switching time interval between the first operation and the second operation during the humidifying ventilation operation. It is desirable to set the value within the range of 70% to 80%.
−実施形態１の効果−
本実施形態の調湿装置（10）では、除湿換気運転中における第１動作と第２動作の切り換え時間間隔が、加湿換気運転中における第１動作と第２動作の切り換え時間間隔よりも短くなっている。つまり、第１空気の湿度が比較的低く、吸着熱交換器（51,52）が概ね飽和状態に達するまでに要する時間が比較的長い加湿運転中には、第１／第２動作の継続時間を長く設定する一方、第１空気の湿度が比較的高く、吸着熱交換器（51,52）が実質的な飽和状態に達するまでに要する時間が比較的短い除湿換気運転中には、第１動作および第２動作の継続時間を短く設定している。
-Effect of Embodiment 1-
In the humidity control apparatus (10) of this embodiment, the switching time interval between the first operation and the second operation during the dehumidification ventilation operation is shorter than the switching time interval between the first operation and the second operation during the humidification ventilation operation. ing. That is, the duration of the first / second operation during the humidification operation in which the humidity of the first air is relatively low and the time required for the adsorption heat exchanger (51, 52) to reach a substantially saturated state is relatively long. While the humidity of the first air is relatively high and the time required for the adsorption heat exchanger (51, 52) to reach a substantially saturated state is relatively short, The duration of the operation and the second operation is set short.

図１３に示すように、本変形例の調湿装置（10）は、冷媒回路（100）と２つの吸着素子（111,112）とを備えている。冷媒回路（100）は、圧縮機（101）と凝縮器（102）と膨張弁（103）と蒸発器（104）が順に接続された閉回路である。冷媒回路（100）で冷媒を循環させると、蒸気圧縮冷凍サイクルが行われる。第１吸着素子（111）及び第２吸着素子（112）は、ゼオライト等の吸着剤を備えている。各吸着素子（111,112）には多数の空気通路が形成されており、この空気通路を通過する際に空気が吸着剤と接触する。 As shown in FIG. 13, the humidity control apparatus (10) of the present modification includes a refrigerant circuit (100) and two adsorbing elements (111, 112). The refrigerant circuit (100) is a closed circuit in which a compressor (101), a condenser (102), an expansion valve (103), and an evaporator (104) are connected in order. When the refrigerant is circulated in the refrigerant circuit (100), a vapor compression refrigeration cycle is performed. The first adsorption element (111) and the second adsorption element (112) include an adsorbent such as zeolite. A large number of air passages are formed in each adsorption element (111, 112), and the air comes into contact with the adsorbent when passing through the air passages.

Outdoor air passes and room air passes through the other. The outdoor air is supplied to the room after passing through the adsorption elements (111, 112), and the room air is discharged to the outside after passing through the adsorption elements (111, 112). In the humidity control apparatus (10) during the simple ventilation operation, the outdoor air and the indoor air are not switched.
