<P>PROBLEM TO BE SOLVED: To provide an air conditioning system using snow capable of drastically reducing operational energy when a cooling load in an intermediate period or the summer season is large by preventing the insufficient humidification of air feeding while effectively performing the outer air cooling using outer air during the intermediate period or the winter season. <P>SOLUTION: A mechanical chamber 2 has: an outer air path 4 communicating with an outer air introduction port 3; a return air path 7 communicating with an air-conditioning objective chamber 6 via an return air intake 5; a mixing part 9 which makes the outer air path 4 divisionally communicate with the return air path 7; and an air-feeding path 11 which divisionally communicates with the mixing part 9 and communicates with the air-conditioning objective chamber 6 via an air-feeding wind path 10. A snow storage part 30 in which snow is deposited is disposed outdoors, a first step humidifier 12 which insulates and humidifies return air RA is disposed at the return air path 7, a cooling coil 15, a second step humidifier 14 which insulates and humidifies mixed air MA and an air-feeding fan 19 are disposed at the air-feeding path 11, an outer air fan 23 is disposed at the outer air path 4, an exhaust fan 27 is disposed at the air-conditioning objective chamber 6, outer air OA and snow-cooled outer air SOA are switched and guided to the outer air path 4, and the cold heat of snow-cooled water 36 is guided to the cooling coil 15. <P>COPYRIGHT: (C)2012,JPO&INPIT |
