Abstract
Pressure detection means are provided to detect a gas pressure in a gas absorption and release container. A judgment portion judges the limit of gas absorption and release on the basis of comparison between the gas pressure detected by the pressure detection means and a setting pressure predetermined in a setting portion. A control portion sends out a control signal to a heat medium means, a gas supply means and a gas transportation means on the basis of the result of the judgment to thereby switch over the operation between gas absorption and gas release.
