7 to the regenerator 18, a heating device 19 is attached to the regenerator 18, and the water vapor from the cooling evaporator 20 is absorbed into the absorbent in the absorber 17. The absorbed water vapor is evaporated and regenerated into the condenser 2.
However, since a liquid absorbent is used, a large amount of thermal energy from the heating device 19 is required to regenerate the steam.
In addition, a heat exchanger 23 for the solution is required to recover the thermal energy, and a pump 22 is required for circulating the absorbent.Moreover, driving the pump 22 requires power and generates vibration and noise. Not only this, but also problems arise in terms of maintenance.Furthermore, the amount of water vapor absorbed by the absorbent itself is extremely small, resulting in an increase in the size of the entire device.
