  • Publication number: 20040129011
    Abstract: Disclosed is an air conditioning apparatus which is provided with two adsorption elements (81, 82). The air conditioning apparatus repeats in alternation an operation in which the second adsorption element (82) is regenerated and, at the same time, air is dehumidified by the first adsorption element (81), and an operation in which the first adsorption element (81) is regenerated and, at same time, air is dehumidified by the second adsorption element (82). Additionally, the air conditioning apparatus includes a refrigerant circuit. The refrigerant circuit performs a refrigeration cycle in which a regenerative heat exchanger (92) operates as a condenser and a first cooling heat exchanger (93) or a second cooling heat exchanger (94) operates as an evaporator. For example, air, which has robbed heat of adsorption in the first adsorption element (81), is further heated by the regenerative heat exchanger (92) and is introduced into the second adsorption element (82).

  • Publication number: 20040123615
    Abstract: Disclosed is an air conditioning apparatus with two adsorption elements (81, 82). The air conditioning apparatus repeatedly alternately performs a first operation in which air is dehumidified by the first adsorption element (81) simultaneously with regeneration of the second adsorption element (82) and a second operation in which air is dehumidified by the second adsorption element (82) simultaneously with regeneration of the first adsorption element (81). At the time of switching between these operations, only the flow path of air is changed, with the adsorption elements (81, 82) remaining stationary. The air conditioning apparatus includes a refrigerant circuit. The refrigerant circuit performs a refrigeration cycle in which a regenerative heat exchanger (92) operates as a condenser and either one of first and second cooling heat exchangers (93, 94) operates as an evaporator.

  • Publication number: 20040050077
    Abstract: An indoor unit (Z1) has a casing (1) which is embedded or suspended in/from a ceiling (50), and an indoor panel (2) which is provided on a lower side of the casing (1) and installed in an indoor exposed state. The indoor panel (2) is provided with an air inlet (3), a plurality of air outlets (4) which surround the air inlet (3) in a rectangular shape and have a rectangular shape. An infrared sensor (15) is provided on an exposed portion of the indoor panel (2). The indoor unit (Z1) further has an airflow changing unit (52) for changing characteristics of airflow blown out from each of the air outlets (4), and a control unit (53) for controlling the airflow changing unit (52) based on output information of the infrared sensor (15).
