In addition, since it has a function of maintaining a substantially constant liquid surface, a predetermined amount of space can be always secured in the vapor phase portion in the liquid pool. Furthermore, since the gas phase part of the liquid pool and the gas phase part in the refrigeration cycle are connected to the air supply pipe, from the gas phase part of the generator to the pressure equalizing pipe, the gas phase part of the liquid pool, and the blower pipe direction. Since the non-condensable gas separated in the liquid pool rises to the gas phase part of the liquid pool in the middle of the gas flow channel, a small amount of the non-condensed gas is absorbed in the rare absorbed liquid. Some of those mixed as bubbles or those dissolved in the rare absorbent are sent to the gas phase part in the refrigeration cycle through the air pipe.
