DEHUMIDIFICATION DEVICE AND DEHUMIDIFICATION SYSTEM

摘要

First and second adsorption heat exchangers are provided for first and second heat exchange chambers, respectively, and each interchangeably function as an evaporator or a condenser. If the first adsorption heat exchanger functions as an evaporator in the first heat exchange chamber, a first adsorption block is arranged at a position downstream of the first adsorption heat exchanger. If the second adsorption heat exchanger functions as an evaporator in the second heat exchange chamber, a second adsorption block is arranged at a position downstream of the second adsorption heat exchanger.

主权项

1. A dehumidification device comprising:
a refrigerant circuit including first and second adsorption heat exchangers loaded with an adsorbent and performing alternately a first operation in which the first adsorption heat exchanger functions as an evaporator to dehumidify air and the second adsorption heat exchanger functions as a condenser to regenerate the adsorbent and a second operation in which the first adsorption heat exchanger functions as a condenser to regenerate the adsorbent and the second adsorption heat exchanger functions as an evaporator to dehumidify the air; first and second heat exchange chambers provided with the first and second adsorption heat exchangers, respectively; a switching mechanism configured to change airflow paths such that air that has passed through one of the first and second heat exchange chambers that is provided with the adsorption heat exchanger functioning as an evaporator is supplied to a humidity-controlled space and that air to regenerate the adsorbent flows through the other heat exchange chamber provided with the adsorption heat exchanger functioning as a condenser; a first adsorption block loaded with the adsorbent, configured to bring air into contact with the adsorbent, and arranged at a position downstream of the first adsorption heat exchanger if the first adsorption heat exchanger functions as an evaporator in the first heat exchange chamber; and a second adsorption block loaded with the adsorbent, configured to bring air into contact with the adsorbent, and arranged at a position downstream of the second adsorption heat exchanger if the second adsorption heat exchanger functions as an evaporator in the second heat exchange chamber.
