た。2. Description of the Related Art In a conventional duct type air conditioner, only heat load treatment has been considered. That is, in order to cope with the heating and cooling load, the air exhausted from the room is mixed with the outside air, and the cold and warm air conditioned by the heating coil, the cooling coil, etc. is supplied to the room through the duct. The simplest method is to use a signal from a thermostat in the room according to the heat load in the room to blow air while the air with a constant air volume is turned on and off as appropriate (constant air volume method), or to the indoor heat load. In response, there was a system (variable air volume system) in which the air flow rate was changed appropriately by the signal from the thermostat in the room.
