Patent ID: 7927406

Claim:
A water droplet generating system comprising: a vessel, which is placed in an atmosphere, and which has an opening portion; a first opening/closing valve, which opens the opening portion when an ambient temperature is lower than a predetermined temperature or when humidity is higher than a predetermined humidity, the first opening/closing valve closing the opening portion when the ambient temperature is higher than the predetermined temperature or when the humidity is lower than the predetermined humidity; a moisture absorbent member, housed in the vessel, the moisture absorbent material constructed to absorb and release water vapor depending on a change of humidity; and a condenser portion disposed to communicate with an inside of the vessel, the condenser portion being constructed to cool the water vapor, which is released form the moisture absorbent member, to a dew point of the water vapor or less; wherein: when the first opening/closing valve opens the opening portion, the moisture absorbent member absorbs water vapor in the atmosphere, when the first opening/closing valve closes the opening portion, the moisture absorbent member releases the water vapor, and the condenser portion condenses the water vapor, which is released from the moisture absorbent member, to generate a water droplet; and the vessel and the condenser portion are connected by a connector that is constructed to permit the water vapor, which is released from the moisture absorbent member, to pass from the vessel to the condenser portion, the connector being made of a material having a heat conductivity lower than a heat conductivity of the vessel and lower than a heat conductivity of the condenser portion.
