According to the first characteristic configuration, the first outside air is conducted to the first heat exchanger and a part of the first sent air that has undergone heat exchange is diverted, and the first diverted sent air and the outdoor air, etc. By adjusting the air volume of the first split-flow delivery air and the air for the first split-flow delivery air, the temperature of the air-fuel mixture of the first split-stream delivery air and the first load-adjusting air can be adjusted. Therefore, by using the air-fuel mixture as the first outside air, it is possible to adjust the temperature of the first outside air as a heat exchange target for the first heat exchanger. The first load adjusting air means the first load adjusting air.
It is air for adjusting the temperature of the outside air. In addition, the second outside air is conducted to the second heat exchanger so that a part of the second delivery air that has exchanged heat is diverted, and the second split delivery air is mixed with the second load adjusting air such as outdoor air.

For example, the first heat exchanger as a condenser, and the second
When performing a heating control experiment with the heat exchanger functioning as an evaporator, the low-temperature second delivery air should be diverted and used as the first load adjustment air for lowering the temperature of the first outside air. Thereby, for example, it becomes possible to perform a heating control experiment even under a high temperature. In addition, for example, when performing a cooling control experiment by making the first heat exchanger function as an evaporator and the second heat exchanger function as a condenser, a first load for adjusting the temperature of the first outside air to increase. By dividing and using the high temperature second delivery air as the adjustment air,

[0006]

According to the first characteristic configuration, the temperatures of the first outside air and the second outside air, which are the objects of heat exchange between the first heat exchanger and the second heat exchanger, are controlled by the air conditioning equipment itself. Since it is possible to adjust the inside of the duct by using the first and second sent air whose temperatures have been exchanged and changed, it is possible to perform a control experiment without separately installing a laboratory and an experimental air conditioner. Moreover, since electric power, fuel, etc. for operating the experimental air conditioner are not necessary, the experimental cost can be reduced. According to the second characteristic configuration, the control experiment can be performed without separately installing the laboratory and the experimental air conditioner, and thereby the experiment cost can be reduced. Moreover, for example, it becomes possible to perform a heating control experiment under a high temperature and a cooling control experiment under a low temperature, and the versatility in the control experiment can be improved.
