Humidity adjusting device

Abstract

The invention discloses a humidity adjusting device. In a casing (11) of a humidity adjusting device (10), a first heat exchanger chamber (37) for receiving a first adsorption heat exchanger (51) and a second heat exchanger chamber (38) for receiving a second adsorption heat exchanger (52) are formed next to each other in the left-right direction. An inside air-side path (32) and an outside air-side path (34) are formed on the rear panel (13) sides of the heat exchanger chambers (37, 38), and an air supply-side path (31) and an air discharge-side path (33) are formed on the front panel (12) sides of the heat exchanger chambers (37, 38). An outside air suction opening (24) and an inside air suction opening (23) are formed to lie to the center in the lateral (left and right) direction of the rear panel (12). An air supply opening (22) is formed to lie to the front of a first side panel (14), and an air discharge opening (21) is formed to lie to the front of a second side panel (15). An air supply fan (26) is connected to the air supply opening (22), and an air discharge fan (25) is connected to the air discharge opening (21). A pressure loss when air passes through inside the casingis suppressed to a low level.

Description

technical field [0001] The invention relates to a humidity adjusting device which uses an adsorbent to adjust air humidity. Background technique [0002] Hitherto, humidity control devices that use adsorbents to control air humidity are known. In Patent Document 1, a humidity control device including an adsorption heat exchanger having an adsorbent carried on its surface is disclosed. [0003] In the humidity control device disclosed in Patent Document 1, a refrigerant circuit including two adsorption heat exchangers is provided. In this refrigerant circuit, an operation in which the first adsorption heat exchanger functions as a condenser and a second adsorption heat exchanger functions as an evaporator and an operation in which the second adsorption heat exchanger functions as a condenser and the first adsorption heat exchanger functions as an evaporator are alternately performed. In an adsorption heat exchanger operating as an evaporator, the moisture in the air is abso...

AI Technical Summary

Problems solved by technology

[0006] As described above, in the humidity control device disclosed in Patent Document 1, it is necessary to make the two kinds of air (outdoor air and indoor air) flow in the housing without mixing with each other, and it is also necessary to control the circulation paths of the above two kinds of air. Switching, so the air circulation path in the housing is easily complicated

Moreover, if the air circulation path in the casing becomes complicated, the flow direction of the air in the casing will suddenly change, which may increase the pressure loss when the air passes through the casing.
