A cooling system utilizes an organic ionic salt composition for dehumidification of an airflow. The organic ionic salt composition absorbs moisture from an inlet airflow to produce an outlet airflow with a reduce moisture from that of the inlet airflow. The organic ionic salt composition may be regenerated, wherein the absorbed moisture is expelled by heating with a heating device. The heating device may be an electrochemical heating device, such as a fuel cell, an electrochemical metal hydride heating device, an electrochemical heat pump or compressor, or a condenser of a refrigerant cycle, which may utilize an electrochemical pump or compressor. The efficiency of the cooling system may be increased by utilization of the waste heat the cooling system. The organic ionic salt composition may circulate back and forth or in a loop between a conditioner, where it absorbs moisture, to a regenerator, where moisture is desorbed by heating.

An absorption type carbon dioxide removal and concentration device can remove or concentrate a carbon dioxide throughout four seasons and can be manufactured with a relatively simple structure. The device includes a carbon dioxide removal rotor that holds a carbon dioxide absorbent. The rotor is divided into at least a treatment zone and a regeneration zone. Air to be treated is ventilated through the treatment zone, so that carbon dioxide contained in the air to be treated is absorbed by a holding absorbent of the rotor portion, so that the CO.sub.2 can be separated and removed from the air to be treated. In the regeneration zone, regeneration air is ventilated, so that the carbon dioxide absorbed by the holding absorbent in the treatment zone is desorbed with the regeneration air to regenerate the holding absorbent. A total heat exchanger recovers latent heat and sensible heat from the regeneration exhaust.

To reduce loss due to water evaporation and to efficiently release moisture from a moisture absorbing portion, in the humidity controller according to the present invention, a moisture absorbing portion (2) is formed to include at least two gel sections each with a different thermal conductivity and to release absorbed moisture from an exposed surface (31) that is a specific region exposed outside and that is disposed on the surface opposite to a heater (5) on the basis of heating by the heater (5).

An apparatus is provided and arranged with an air control system to alternately direct a first and a second airflow to a first and a second energy-absorbing body in order to achieve a heat and moisture transfer between the two airflows. The energy exchange bodies alternate between recovery and release modes such that when one energy exchange body is in the release mode the other is in the recovery mode. Each of the first and second energy absorbing bodies is divided into a first latent energy recovery portion which includes a moisture absorbent material so that it is arranged to absorb latent energy and a second sensible energy recovery portion which is substantially free from moisture absorbent material so as to absorb primarily sensible energy.
