Abstract: An air conditioner has a heat exchanger, an absorbing agent, and a controller. The absorbing agent performs an absorbing operation for absorbing moisture in passing air flowing through the heat exchanger functioning as an evaporator and a regenerating operation for desorbing moisture from passing air heated by the heat exchanger functioning as a condenser. The controller performs control such that the absorbing operation and the regenerating operation are switched at a predetermined switching time interval. The controller also performs control of a capacity of a compressor and control for changing the predetermined switching time interval such that a predetermined load out of a total heat load, which is the sum of the latent heat load and the sensible heat load, is preferentially processed.

Abstract: The invention provides an air conditioner that is capable of performing optimal control in accordance with the environment of an indoor space at startup, and a method of controlling such. The air conditioner forms a refrigerant circuit, having a first heat exchanger, a second heat exchanger, thermistors, humidity sensors, a temperature sensor, ventilation fans, a compressor, a casing, a control unit, and the like. The control unit is connected to the temperature sensor, the humidity sensors, a storage unit, a timer, a manual input unit, air passageway switching mechanisms, a four-way switching valve, and an expansion valve. In the stage before the air conditioner starts normal operation after startup, the control unit performs a priority control operation that prioritizes either the sensible heat process or the latent heat process.

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 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.

On the other hand, in the indoor heat exchanger (22), air is cooled or heated. Then, the air cooled or heated by the indoor heat exchanger (22) is supplied to the room to cope with sensible heat load in the room.

Abstract: A humidity controller apparatus (20) contains an adsorption rotor (24) and a heater (25). A first passage (21) along which a first air stream flows and a second passage (22) along which a second air stream flows are formed in the humidity controller apparatus (20). The amount of heat exchange between the first and second air streams and the amount of moisture exchange between the first and second air streams vary by adjustment to the rotating speed of the adsorption rotor (24), and the humidity controller apparatus (20) is switched between a dehumidification operation and a humidification/heating operation. During the dehumidification operation, the rotating speed of the adsorption rotor (24) is set low. The first air stream is dehumidified by the adsorption rotor (24) and then supplied to the inside of a room. The second air stream is used for regeneration of the adsorption rotor (24) and then discharged to the outside of the room.
