PURPOSE:To obtain an ultralow noise type, floor type ventilation unit for air conditioning by which simultaneous introduction of outside air into a room and exhaust thereof by one apparatus and also simultaneous supply of humidified air as occasion demands can be executed and the possibility of outflow of a sound of noise can be eliminated. CONSTITUTION:In a floor type ventilation unit for air conditioning, a total enthalpy heat exchanger 2 is installed in the center of an apparatus and a U-shaped airing passage 3 communicating laterally is formed on the right and the left of the total enthalpy heat exchanger 2 as the axis, while both of right and left chambers in the upper part of the airing passage 3 are divided into an air supply chamber 4 and an air return chamber 4a, and an exhaust chamber 5 and an outside air introducing chamber 5a, by partition plates A and B respectively. A heat exchanger coil 12, a humidifier 13, a drain pan 14, a control device 15 and other mechanism devices are provided by using a space part of each chamber, while a muffling chamber is so provided in the upper part of a body 1 of the apparatus as to be integral with and continuous to the body. |
