  This type of conventional air-conditioning ventilation system is provided with a control means for controlling the air-conditioning apparatus and the ventilation apparatus. As the control information of the control means, indoor state quantities such as indoor air temperature and humidity are often captured as main information. In such a system in which an air-fuel mixture obtained by mixing outside air and room air is processed and supplied to the room, the installation location of the state quantity detection means for detecting the state quantity becomes a problem. When the air conditioner is provided, the state quantity of the indoor air cannot be accurately detected, and even when it is provided indoors, it is difficult to detect the same accurate state quantity depending on the route through which the processing air flows. The indoor air inlet of the ventilator installed in a sanitary or the like is the most downstream part of the indoor air flow path, so that the state quantity of the indoor air can be detected accurately if the state quantity detection means is arranged in the part. However, the air conditioner and the ventilator are often installed apart from each other, resulting in troublesome problems such as wiring problems.

  In addition, with regard to operating noise, systems built in condominiums, etc. use a technology that reduces the noise by taking a longer creepage distance because the distance between the intake chamber that takes in indoor air and the air conditioner becomes considerably shorter. It is not possible.

The ventilator is an intake / exhaust type heat exchange ventilator and is provided behind the ceiling of a sanitary or the like, and an indoor air inlet for exhaust is communicated with a room of the sanitary or the like via a duct. The outside air inlet of the ventilator is connected to the outside by a duct, and the outside air outlet is connected to the intake chamber by a duct. That is, the processing air is an air-fuel mixture in which the outside air after heat exchange and room air are mixed, and is cooled and warmed by a cooling coil or a heating coil and supplied to each room as cooling / heating air. The intake chamber has an indoor intake port for taking in indoor air on the lower surface, an inlet port for introducing outside air from the ventilator on one side, and an outlet for an air-fuel mixture on the opposite side. And the state quantity detection means which detects the state quantity of room air is provided in the place which remove | deviated from the line which connects the inlet and outlet of an indoor suction inlet, and a detection output is output to the control means provided in the air conditioner. The control means controls the air conditioner and the ventilator based on this detection output. In addition, the intake chamber is provided with a silencing structure in the form of a transverse bowl between the outlet and the indoor suction port, and the duct connecting the outlet and the air conditioner is also provided with a silencing structure in the upper and lower staggered areas.

  In this air-conditioning ventilation system, since the indoor air state quantity is provided at a location away from the inlet of the indoor suction port, the indoor air state quantity can be reliably detected and sent as control information to the control means. Control operation with high accuracy is possible. The operating noise propagating from the air conditioner is attenuated by the barrier effect due to the silencer structure of the duct and the attenuation effect due to the length of the creepage distance, and further attenuated by the silencer structure of the intake chamber, and is not transmitted to the room much.
