PURPOSE:To get a desired air feeding having a desired temperature and a desired humidity as well as to improve a rate of heat recovery by a method wherein a cooling operation is carried out by evaporating latent heat and humidifying is carried out by water oozed out of the surface of a sintered metallic pipe as required, for every portion of coils positioned in an air passage. CONSTITUTION:Each of portions of coils 16 arranged in an air passage 14A is enclosed by a sintered metallic pipe 41, both ends are closed to form a water chamber 42, water W from a water pump 18 is supplied to the water chamber 42 through a longitudinal water distribution pipe 43 and each of branch pipes 44. For example, in winter season, in a case that outdoor air A of 0 deg.C and 50% is to be sucked, water W is supplied to the water chamber 42 with a desired pressure, resulting in that the water W is oozed out at the surface of the sintered metallic pipe 41 and evaporated. So, a similar effect to that of water spraying can be attained, its temperature and humidity are increased, so a supply air (a) having 14 deg.C and 60% can be provided. In the discharging side heat exchanger 2, the water W is not supplied, but the return air (e) of 26 deg.C and 50% from the chamber R becomes a discharged gas E of 12 deg.C and 75%.
