PURPOSE:To provide a cooling device, the power consumption of which is small and yet which gives an excellent sense of cold air, by a method wherein a humidifier and a heat exchanger are combined. CONSTITUTION:A humidifier 2a has a honeycomb structure consisting in alternately laminating plane plates and corrugated plates, both of which are made of hydrophilic material and also active carbon fiber paper. The air sucked from the suction port 32 of a blower 3 is divided into two flow passages, one of which is led to the humidifier 2a (as indicated with the arrow A) while the other of which is led to a heat exchanger 1 (as indicated with the arrow B).The air flow A is cooled due to the latent heat of evaporation of the water contained in the active carbon fiber paper of the humidifier 2a and sent out as the air flow A'. The air flow A' is heat-exchanged with said air flow B at the heat exchanger 1 and exhausted from an exhaust port 55 in the form of high temperature and high humidity air flow A''. On the other hand, the air flow B is turned into the air flow B' after being removed its heat and cooled by said heat- exchange with the air flow A' and then blown-off from a cold air outlet 56. The temperature of the air flow B' blown-off from the cold air coulet 56 is lowered by about 5 deg.C than that of suction air or the atmospheric temperature without no rise of absolute humidity, resulting in obtaining excellent cooling performance. |
