Description

  The present invention relates to a humidity control apparatus that adjusts the humidity of air and performs a so-called batch operation.

  Conventionally, as disclosed in Patent Document 1, for example, a humidity control device that adjusts the humidity of air using an adsorbent and a refrigeration cycle is known. This humidity control apparatus is configured to perform a so-called batch-type operation.

  The humidity control apparatus includes two adsorption units. Each adsorption unit is configured by a mesh container filled with an adsorbent and a refrigerant pipe that passes through 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 guided to the adsorption unit serving as a condenser, and the air supply 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 in 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 the adsorption unit serving as an evaporator, and the moisture in the air supply 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. And this heat exchange member is comprised so that an adsorbent may be heated and cooled with the fluid which flows through the inside of a copper pipe.

Further, as a humidity control apparatus that performs a batch-type operation, for example, one disclosed in Patent Document 3 is also known. This humidity control apparatus includes two adsorption elements each having a large number of air passages. When the first air is dehumidified by the first adsorption element, the second air heated by the condenser of the heat pump is sent to the second adsorption element to regenerate the adsorbent. Conversely, when the first air is dehumidified by the second adsorption element, the heated second air is sent to the first adsorption element to regenerate the adsorbent. This humidity control apparatus repeats the above two operations alternately to supply dehumidified first air or humidified second air into the room.

  By the way, when humidifying a large space such as a floor in a building, it is necessary to use a humidity control device with a large capacity, and it can be installed near a wall or in a machine room while having such a large capacity device. A compact floor-standing humidity control device is desired. However, there is no floor-mounting type conventional humidity control apparatus as described above, and naturally, no consideration has been given to the configuration of a compact humidity control apparatus suitable for floor-standing.

  The present invention has been made in view of such points, and the object of the present invention is to provide a humidity control apparatus that performs so-called batch-type operation, and devise the arrangement of its internal components to place on the floor. It is in obtaining the structure of the compact humidity control apparatus suitable for.

  In order to achieve the above object, according to the solution means of the present invention, the inside of the casing (11) is vertically divided, and two heat exchangers having an adsorbent supported on the surface in the upper space (17). (61, 62) was placed, while fans (25, 26), etc. were placed in the lower space (18).

  Specifically, in the first aspect of the invention, the first air and the second air are taken in, one of the dehumidified first air and the humidified second air is supplied into the room, and the other is discharged outside the room. Targets humidity control equipment.

  The first and second heat exchangers (61, 62) carrying adsorbents on the respective surfaces are connected to perform a refrigeration cycle, and a refrigerant circuit (60) configured to be able to reverse the refrigerant circulation direction. ), A casing (11) in which the heat exchanger (61, 62) is disposed in an air passage formed therein, and an air supply fan disposed in the air passage in the casing (11) (25), the exhaust fan (26), and the heat exchanger (61, 62) through which the first air passes through the one serving as the evaporator and the second air through the one serving as the condenser. A switching mechanism for switching the air flow path in the casing in accordance with the direction of refrigerant circulation in the refrigerant circuit (60) so that the air passes through the casing. The casing (11) is formed in a box shape and stands upright. And the interior is divided into top and bottom, and in the upper space (17) In which the first and second heat exchangers (61, 62) are disposed, and the air supply and exhaust fans (25, 26) are disposed in the lower space (18). And

  With this configuration, the first air is removed from the evaporator by switching the flow path of the air in the casing in accordance with the switching of the refrigerant circulation direction of the refrigerant circuit in which the two heat exchangers carrying the adsorbent on the surface are connected. It is possible to realize a humidity control device that passes through one of the heat exchangers acting as a dehumidifier and humidifies the second air through the other heat exchanger acting as a condenser, for example, The inside of the casing standing upright on the floor or floor of the machine room is divided into upper and lower parts, the heat exchanger is placed in the upper space, and the fan etc. are placed in the lower space. The configuration of the humidity control apparatus can be obtained.

  And as above-mentioned, when arrange | positioning the heat exchanger (61, 62) and the fan (25, 26) up and down in a casing (11), when arrange | positioning in the left and right or front and back in a casing (11) In comparison, the depth or width of the device can be made relatively small.

  Therefore, it is possible to obtain a humidity control device that can be placed on the floor even in places where the installation space is limited, such as near a wall or machine room.

  In the above-described configuration, the first and second heat exchangers (61, 62) are either left or right or top and bottom when viewed from the front of the casing (11) so that air passes in the front-rear direction of the casing (11). It is preferable that they are arranged side by side (invention of claim 2). If it carries out like this, two heat exchangers (61, 62) can be arrange | positioned if there is space in the depth direction of a casing (11) by the thickness, and can make the depth dimension of a casing (11) small. .

For example, when it is intended to be installed in a building, the loading work depends on the size of the elevator or the entrance. May become difficult. Therefore, in the humidity control apparatus, the portion forming the upper space (17) in which the heat exchanger (61, 62) is housed constitutes the main body (92), and the air supply and exhaust fans (25, 26) ) Forming the lower space (18) accommodated constitutes the machine room part (91), and the main body part (92) and the machine room part (91) are combined and integrated ( Invention of Claim 5).

  This makes it possible to divide and transport the humidity control device into the upper body part (92) and the lower machine room part (91), without being restricted by the size of the elevator or the entrance. It can be easily carried into the building. Further, in the installation work, the united parts can be combined to form an integrated humidity control device, so that the installation work is relatively easy as compared with the case of assembling from parts.

It is preferable that it arrange | positions so that it may open toward either one of these (invention of Claim 7). In this way, even if the multiblade fan is larger in the radial direction than in the thickness direction, the depth dimension of the casing (11) can be obtained by installing the thickness direction in the front-rear direction of the casing (11), that is, in the depth direction. It is possible to install fans (25, 26) in a compact manner without increasing the size.

  On the other hand, in the case of the multi-blade fan as described above, the suction port (25a, 26a) of the fan (25, 26) may be arranged so as to open toward either the upper side or the lower side of the casing (11).
