Embodiment Construction

[0060] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0061] (the first embodiment of the invention)

[0062] The first embodiment of the present invention will be described. The air conditioning device (10) in this embodiment performs a vapor compression refrigeration cycle by circulating a refrigerant in the refrigerant circuit (40). Both the sensible heat load and the latent heat load in the room are processed.

[0063] like figure 1 As shown, the air conditioning device (10) is formed as a so-called split type, and includes an indoor unit (11) and an outdoor unit (12). The indoor unit (11) includes an indoor heat exchanger (55), a first adsorption heat exchanger (56) and a second adsorption heat exchanger (57), and is installed indoors. The indoor unit (11) is configured as a so-called wall-mounted type, and is mounted on a wall surface of the room. On the other hand, the outdoor unit (12) i...

Abstract

A refrigerant circuit (40) is provided with two adsorption heat exchangers (56, 57) in addition to an outdoor heat exchanger (54) and an indoor heat exchanger (55). The indoor heat exchanger (55) and the two adsorption heat exchangers (56, 57) are disposed in an indoor unit (11), while the outdoor heat exchanger (54) is disposed in an outdoor unit (12). In the adsorption heat exchanger (56, 57) serving as an evaporator, moisture in the air is adsorbed by the adsorbent. In the adsorption heat exchanger (56, 57) serving as a condenser, moisture is desorbed from the adsorbent and then applied to the air. Then, the air dehumidified or humidified by the adsorption heat exchanger (56, 57) is supplied to a room to cope with latent heat load in the room. On the other hand, in the indoor heat exchanger (55), air is cooled or heated. Then, the air cooled or heated by the indoor heat exchanger (55) is supplied to the room to cope with sensible heat load in the room.

Description

technical field [0001] The present invention relates to an air conditioning device for treating indoor sensible heat load and latent heat load. Background technique [0002] Up to now, as disclosed in International Publication No. 03 / 029728 pamphlet, there has been known an air-conditioning apparatus for cooling and dehumidifying a room. This air conditioner includes a refrigerant circuit provided with an outdoor heat exchanger on the heat source side and an indoor heat exchanger on the utilization side. A refrigeration cycle is performed by circulating a refrigerant in this refrigerant circuit. Furthermore, in the air conditioning apparatus, the evaporation temperature of the refrigerant in the indoor heat exchanger is set lower than the dew point temperature of the indoor air, and the moisture in the indoor air is condensed, thereby dehumidifying the room. [0003] On the other hand, as disclosed in Japanese Patent Application Laid-Open No. 7-265649, there is also known ...
