摘要： In an air conditioning system, a thermal source device generates cold water from cooling water cooled by a cooling tower. A cooling water circulation passage allows circulation of the cooling water between the cooling tower and the thermal source device. A first heat exchanger exchanges heat between air and the cold water. A cold water circulation passage allows circulation of the cold water between the thermal source device and the first heat exchanger. A second heat exchanger exchanges heat between the cooling water cooled by the cooling tower and the air heat-exchanged with the cold water by the first heat exchanger. A cooling water branch passage, introduces to the second heat exchanger the cooling water introduced to the thermal source device from the cooling tower, and introduces to the cooling water circulation passage the cooling water heat-exchanged with the air by the second heat exchanger.

摘要： An air treatment apparatus includes: a total heat exchanger; a heat supply device having a heater and a cooler; an upper damper; and a complex dehumidification device having a first stationary desiccant and a second stationary desiccant. The upper damper allows return air (RA) to flow into one of the first stationary desiccant and the second stationary desiccant, and allows outdoor air (OA) to flow into the other one of the first stationary desiccant and the second stationary desiccant. The upper damper switches between a return air path and an outdoor air path so that the return air (RA) and the outdoor air (OA) pass through different ones of the first stationary desiccant and the second stationary desiccant.

摘要： A control unit determines, on the basis of a temperature and humidity detected by sensors, whether outdoor air cooling that takes outdoor air into a room is effective. Upon determination that the outdoor air cooling is effective, the control unit opens a damper and causes stoppage of an air supply fan disposed in an air supply path. Due to such operation, indoor air passing through an air discharge path bypasses a total heat exchanger by passing through a bypass air path, and thereby is discharged to the outdoors as exhaust air. However, due to stoppage of the air supply fan, although the outdoor air does not flow through the air supply path, the outdoor air flows into a building from an opening of the building.

摘要： A ventilator includes an exhaust air duct for exhausting air from an interior space to an outside and a supply air duct for supplying air from the outside to the interior space, and is equipped with a heat exchanger and a defroster. The heat exchanger performs heat exchange between air passing through the exhaust air duct and air passing through the supply air duct. The defroster defrosts, when frost attaches to the heat exchanger, the heat exchanger by, after air flows into the exhaust air duct or the supply air duct, changing a state of the air.
