Open-cycle type air conditioner

Abstract

An open-cycle type air conditioner includes three major passges; a room air passage defined between a room air inlet and a room air outlet; an outside air passage defined between an outside air inlet and an outside air outlet; and a regenerative air passage defined between a regenerative air inlet and a regenerative air outlet. A room air blower unit is disposed in the room air passage face to face with the room air inlet. A rotary latent heat exchanger which preferably comprises polyester un-woven fiber impregnated with lithium chloride extends over the room air passage and the regenerative air passage with its side walls in a horizontal direction. The rotary latent heat exchanger is located on the downflow side of the regenerative inlet. There is further provided a rotary sensible heat exchanger disposed on the downflow side of the rotary latent heat exchanger in the room air passage and extending over the room air passage and the outside air passage with its side walls disposed in a horizontal direction and being in communication with the outside air outlet. A first rotary filter type humidifier is disposed on the downflow side of the rotary sensible heat exchanger and in the neighborhood of the room air outlet, while a second rotary filter type humidifier is disposed in the outside air passage and in the neighborhood of the outside air inlet. An outside air blower unit is disposed on the downflow side of the second rotary filter type humidifier in the outside air passage and a regenerative air blow unit is disposed on the downflow side of the rotary latent heat exchanger in the regenerative air passage and in the neighborhood of the regenerative air outlet.
