DEHUMIDIFICATION SYSTEM

摘要

A dehumidification system equipped with a dehumidification unit that uses two adsorption heat exchangers (46, 47) which are alternately switched between an adsorption side and a regeneration side, said dehumidification system being provided with a front-stage dehumidification unit (20) and a rear-stage dehumidification unit (30). In addition, by providing an outdoor circulation circuit (11) in which outside air circulates between the regeneration side of the front-stage dehumidification unit (20) and an outdoor space, providing an indoor circulation circuit (12) in which indoor air circulates between the adsorption side of the rear-stage dehumidification unit (30) and a space (S) to be dehumidified, and providing an intermediate circulation circuit (13) in which air circulates between the adsorption side of the front-stage dehumidification unit (20) and the regeneration side of the rear-stage dehumidification unit (30), a configuration is implemented whereby the dew point temperature of the indoor air can be lowered without raising the regeneration temperature.
