A humidity control apparatus for realizing the dehumidification, humidification, and ventilation operations in a compact configuration. The apparatus includes a rotary humidity control element, an electric heater, and sucking and/or forcing blowers. The rotary humidity control element is of metal silicate gel polymerized in honeycomb laminates of ceramics, and is sectioned into a drying function part, a heat recovery function part, and a humidification function part, for use. The drying function part absorbs and removes moisture from air passing therethrough at room temperatures. The heat recovery function part recovers heat of air passing therethrough. The humidification function part moistens the air passing therethrough if the air is high in temperature. The electric heater is provided on an air passageway between the heat recovery function part and the humidification function part, for heating the air to be introduced to the humidification function part. The first suction- or forcing blower is provided on a first air passageway, and the second suction- or forcing blower is provided on a second air passageway. By the action of the blowers, an outdoor and interior airs are fetched from the exterior and the interior respectively, passed through the rotary humidity control element, and discharged. The air passageways are changed so that the apparatus is operated for dehumidification, humidification, or ventilation selectively.

A compact and effective ventilator/drier assembly for heating the room to which it is installed has a case main body 1 divided into a primary zone 3A communicating with an air inlet port 2A, a tertiary zone 3C communicating with an air outlet port 2B and a secondary zone 3B disposed adjacent to the tertiary zone and the primary zone. Moist air A in a room 100 is forced to flow through the air inlet port, the primary zone, the secondary zone, the tertiary zone and the air outlet port and back into the room by a centrifugal type air blower 21 and moisture contained in the room air is adsorbed by a cylindrical rotary type moisture adsorbing device 31 arranged between the secondary zone and the tertiary zone as the air is made to come into contact with a moisture-removing portion 31A of the adsorbing device 31. Dried air B is moved to into the tertiary zone, where it is heated to produce heating air E, which is discharged from the air outlet port into the room. At the same time, the heat recovered by the heat recovering portion 31C of the rotary type moisture adsorbing device is utilized to heat regenerating air C, which is led to the tertiary zone by a drying/heating changeover damper 48 and then discharged from the air outlet port.

Ventilator/dryer assembly using moisture adsorber

An absorption refrigeration system having a generator, a rectifier, a condenser, an evaporator, an absorber and heat exchangers which are connected by means of conduits in an airtight manner so that circulations for refrigerant and for absorbent solution are formed, wherein the rectifier is mounted upright above the generator, and wherein a receiver for receiving absorbent containing refrigerant is mounted below the rectifier and communicates with the lower portion of the generator through an absorbent passage means, whereby decreasing hindrance of the generation of the refrigerant vapor from the generator, thus increasing the efficiency in generating vapor and, at the same time, preventing local overheating of the solution in the generator.
