The direct air absorbing air conditioning ventilation device has high efficiency absorbent aqua as medium and heat source in temperature higher than 50deg.C as thermal power. It heats the absorbent aqua to evaporate its partial water for concentrating regeneration, absorbs water vapor from fresh air with concentrated absorbent aqua in high hygroscopicity to lower the humidity and temperature of the air, and freshness the indoor air with the air with lowered humidity and temperature. The direct air absorbing air conditioning ventilation device has low power consumption, simple manufacture, low cost and environment friendship. |
