A humidity control apparatus performs a humidification operation in which outdoor air is supplied to the inside of a room through a moisture-desorption adsorption heat exchanger serving as a condenser and room air is discharged to the outside through a moisture-absorption adsorption heat exchanger serving as an evaporator. The humidity control apparatus includes a preheat heat exchanger which, in the humidification operation, is positioned upstream of the moisture-desorption adsorption heat exchanger in the flow of outdoor air in an air passage and serves as a condenser to heat outdoor air in a refrigerant circuit, and a heat-recovery heat exchanger which, in the humidification operation, is positioned downstream of the moisture-absorption adsorption heat exchanger in the flow of room air in the air passage and serves as an evaporator to recover heat from room air in the refrigerant circuit. |

1. A humidity control apparatus including
a refrigerant circuit configured such that
a compressor, an expansion mechanism, and two adsorption heat exchangers on each of which an adsorbent is supported are connected together through a pipe,a refrigerant circulation direction is reversible, anda vapor compression refrigeration cycle is performed, and an air passage configured such that an air flow path switches, depending on the refrigerant circulation direction in the refrigerant circuit, so as to
cause one of room air or outdoor air taken into the air passage to pass through one of the adsorption heat exchangers serving as a moisture-desorption adsorption heat exchanger functioning as a condenser andcause the other one of the room air or the outdoor air to pass through the other one of the adsorption heat exchangers serving as a moisture-absorption adsorption heat exchanger functioning as an evaporator, in which a humidification operation is performed, in which
the outdoor air is supplied to an inside of a room through the moisture-desorption adsorption heat exchanger, andthe room air is discharged to an outside through the moisture-absorption adsorption heat exchanger, the humidity control apparatus comprising: a preheat heat exchanger connected to the refrigerant circuit and
in the humidification operation, positioned upstream of the moisture-desorption adsorption heat exchanger in a flow of the outdoor air in the air passage and serving as a condenser to heat the outdoor air; and a heat-recovery heat exchanger
connected to the refrigerant circuit andin the humidification operation, positioned downstream of the moisture-absorption adsorption heat exchanger in a flow of the room air in the air passage and serving as an evaporator to recover heat from the room air. |
