- the open / close damper for the opening (158) is in the closed state.
- the outdoor air (OA) flowing through the rear lower passage (144) flows into the lower space of the second heat exchange chamber (42) from the second rear lower opening (154).
- This air flows from the lower surface of the second filter (124b) toward the upper surface.
- dust in the air is collected on the lower surface of the second filter (124b).
- this air passes through the inflow space of the second heat exchanger (62) and flows into the upper space of the second heat exchange chamber (42).
- the second heat exchange (62) functioning as a condenser, the adsorbent is heated by the refrigerant, the adsorbent removes moisture, and the desorbed moisture is provided to the air.
- the dust that has been removed by the second filter (124b) and the air that has been humidified by the second heat exchange (62) pass through the front upper passage (145) through the second front upper opening (156). Flows into Then, after flowing through the air supply side passageway (131), the air is supplied from the air supply port (117) to the indoor space as humidified air (SA).
- the room air (RA) flowing through the rear upper passage (143) flows into the upper space of the first heat exchange chamber (41) from the first rear upper opening (151). Then, this air flows downward and flows through the inflow space of the first heat exchanger (61).
- moisture in the air is adsorbed by the adsorbent of the first heat exchanger (61) functioning as an evaporator. The heat of adsorption generated at this time is absorbed by the refrigerant in the first heat exchange (61).
- the air that has passed through the first heat exchanger (61) flows from the upper surface of the first filter (124a) toward the lower surface.
- the dust collected on the lower surface of the first filter (124a) by the above-described first operation is blown off by the air flowing down the first filter (124a), and the dust on the lower surface of the first filter (124a) is removed. Dust is removed. Then, the dust is pressure-fed to the outside of the first heat exchange chamber (41) by the air having passed through the first filter (124a).
- the outdoor filter (124) is arranged and formed on the inflow surfaces of the first and second heat exchangers (61, 62), so that the outdoor filter (124) is installed. This can reduce the increase in pressure loss caused by the pressure. Further, by automatically removing dust attached to the outdoor filter (124) by the indoor air (RA), the frequency of maintenance and replacement of the outdoor filter (124) can be reduced.
- the first and second outlets (161a, 161b) are provided in the right side plate (110a) of the main body casing (11). Therefore, as shown in FIG. 15, the indoor filter (123b) can be taken out of the main casing (11) from the first outlet (161a) for maintenance, while the outdoor filter (124) can be taken out of the second filter (124). It can be taken out of the main casing (11) from the outlet (161b) for maintenance. Therefore, maintenance / exchange of each filter (123b, 124) can be easily performed.
- the air supply outlet (24) is provided below the air supply fan (25) on the bottom plate (not shown) of the main casing (11).
- the outdoor air suction duct (71) is connected to the outside air suction port (21) of the fourth side plate (15) of the main body casing (11), and the exhaust air outlet duct (23) is connected to the exhaust air outlet (23). ) Can be connected. This eliminates the need to provide ducts (72, 74) that communicate with the room, so that the space above the ceiling can be used more effectively.
- the main body casing (11) may be installed on the floor instead of the ceiling.
- the compressor unit (91) is arranged outdoors, but may be arranged indoors at a position where sound is not bothersome.
- it is configured separately from the living room that people usually use, and it is a machine room equipped with equipment and equipment, and a place far from the room above the ceiling.
- the noise of the compressor (63) should be confined by the compressor casing (92). It comes out.
- the four-way switching valve (64) is used as the reversing mechanism.
- the circulation direction of the refrigerant may be reversed by connecting four electromagnetic valves in a bridge shape. .
- the first and second heat exchanges are configured by the cross-fin type fin-and-tube heat exchangers, but are not limited thereto.
- Other types of heat exchange for example, corrugated fin type heat exchange may be used.
- the present invention is useful for a humidity control device that performs regeneration and cooling of an adsorbent by performing a refrigeration cycle.
