  The present invention relates to a humidity control device that adjusts the humidity of air, and particularly to a device that regenerates or cools an adsorbent by performing a refrigeration cycle.

  2. Description of the Related Art Conventionally, as disclosed in, for example, Patent Document 1, a humidity control device that adjusts air humidity using an adsorbent and a refrigeration cycle is known. This humidity control apparatus includes two adsorption units. Each adsorption unit is constituted by a mesh container filled with an adsorbent and a refrigerant pipe penetrating the mesh container. The refrigerant pipe of each adsorption unit is connected to a refrigerant circuit that performs a refrigeration cycle. The humidity control apparatus is provided with a damper for switching the air sent to each adsorption unit.

  During the operation of the humidity control apparatus, the compressor of the refrigerant circuit is operated, and a refrigeration cycle in which one of the two adsorption units is an evaporator and the other is a condenser is performed. In the refrigerant circuit, the refrigerant circulation direction is switched by operating the four-way switching valve, and each adsorption unit functions alternately as an evaporator or a condenser.

  In the humidifying operation of the humidity control apparatus, the air supply flowing from the outside to the room is led to the adsorption unit serving as a condenser, and the supply air is humidified with moisture desorbed from the adsorbent. At that time, the exhaust gas flowing from the inside to the outside of the room is led to the adsorption unit serving as an evaporator, and the moisture in the exhaust gas is collected into the adsorbent. On the other hand, in the dehumidifying operation of the humidity control apparatus, the air supply flowing from the outside to the room is led to an adsorption unit serving as an evaporator, and moisture in the intake air is adsorbed by the adsorbent. At that time, the exhaust flowing from the room to the outside is led to the adsorption unit serving as a condenser, and the moisture desorbed from the adsorbent is discharged together with the exhaust to the outside.

In addition, as what has the same function as the said adsorption | suction unit, the heat exchange member as disclosed, for example in patent document 2 is also known. In this heat exchange member, plate-shaped fins are provided around the copper tube, and an adsorbent is carried on the surfaces of the copper tube and the fins. The heat exchange member is configured to heat and cool the adsorbent with a fluid flowing in the copper pipe.

  By the way, in the said conventional humidity control apparatus, in order to reproduce | regenerate an adsorbent, it is necessary to change the circulation direction of a refrigerant | coolant in a refrigerant circuit frequently, and there exists a subject that a sound generate | occur | produces each time.

  The present invention has been made in view of such points, and the object of the present invention is to provide a quiet and comfortable humidity control apparatus by separating the sound source from the main casing of the humidity control apparatus installed indoors. May be offered.

  In order to achieve the above object, in the present invention, the compressor unit (91) including the compressor (63) of the refrigerant circuit (60) is disposed outside the main casing (11).

  Specifically, the first invention is directed to a humidity control apparatus that supplies one of the dehumidified first air and the humidified second air to the room and discharges the other to the outside.

  Then, the first and second heat exchangers (61, 62) carrying the adsorbent are connected to perform a refrigeration cycle and the refrigerant circulation direction can be reversed, and the above-described heat is supplied to the internal air passage. The first air passes through the main casing (11) in which the exchanger (61, 62) is installed and the heat exchanger (61, 62) serving as an evaporator to become a condenser. Main body unit (90) provided with a switching mechanism for switching the air flow path in the main body casing (11) according to the refrigerant circulation direction in the refrigerant circuit (60) so that the second air passes through ) And a compressor unit (91) provided outside the main casing (11) and provided with the compressor (63) of the refrigerant circuit (60).

  According to the above configuration, the two refrigeration cycle operations are alternately repeated by switching the reversing mechanism (64) in the refrigerant circuit (60). During the first refrigeration cycle operation, the second air is sent to the first heat exchanger (61) serving as a condenser, and the first air is sent to the second heat exchanger (62) serving as an evaporator. . In the first heat exchanger (61), 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 heat exchanger (62), the 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 second refrigeration cycle operation, the switching mechanism switches to a different flow path from that during the first refrigeration cycle operation, and the first air is sent to the first heat exchanger (61) serving as the evaporator. Then, the second air is sent to the second heat exchanger (62) serving as a condenser. In the first heat exchanger (61), the 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 heat exchanger (62), the adsorbent is regenerated by being heated by the refrigerant, and moisture desorbed from the adsorbent is given to the second air.

It consists of a multi-blade fan that sucks from the side and blows forward, and is arranged so that the axial center of the impeller faces the thickness direction of the main casing (11).

  According to said structure, since the compressor (63) is arrange | positioned on the outer side of a main body casing (11), the thickness of a main body casing (11) is not restrict | limited to the height of a compressor (63), When a thin fan with a small size of the entire fan in the axial direction of the impeller is arranged with respect to the diameter of the impeller so that the axial center of the impeller faces the thickness direction of the main casing (11), The thickness of the main casing (11) can be reduced.

  In the eighth invention, the first and second heat exchangers (61, 62) are arranged so that air passes in the thickness direction of the main casing (11).

  According to said structure, the 1st and 2nd heat exchanger is set so that the thickness direction of a main body casing (11) and the thickness direction of a 1st and 2nd heat exchanger (61, 62) may correspond substantially. Since (61, 62) is arranged, the thickness of the main casing (11) can be further reduced.

  In the ninth invention, the main casing (11) is connected to the air outlet (24) and the inlet (22) for connecting the ducts (72, 74) communicating with the room, and the duct (71 , 73) are connected to the air outlet (23) and the air inlet (21), respectively.

  According to said structure, a humidity control apparatus can be arrange | positioned in an optimal position by utilizing the duct (71,72,73,74) which makes indoors and the outdoors, and a main body casing (11) communicate.

  The humidity control apparatus of the tenth invention is installed behind the ceiling. The humidity control apparatus according to the eleventh aspect is installed on an indoor floor.

  According to these inventions, it is possible to obtain a humidity control apparatus that exhibits the effects of the present invention remarkably even when it is disposed on the back of a ceiling or on an indoor floor.

  In the twelfth aspect of the invention, the main casing (11) includes a blowout opening (24) and a suction opening (22) for directly communicating the inside of the main casing (11) and the room, and a duct (71, 71) communicating with the outside. 73) are connected to the air outlet (23) and the inlet (21), respectively.

  According to the above configuration, since it is not necessary to provide ducts (72, 74) communicating with the room, a space such as a ceiling can be used effectively.

  As described above, according to the present invention, the compressor (63) that generates sound when the refrigerant circulation direction is switched is arranged on the side of the compressor unit (91) separately from the main casing (11). As a result, a quiet and compact humidity control device can be obtained.
