In one embodiment, two fans 32 are provided, which may be provided at the clean air inlet 42 and outlet 43 positions, respectively, to enhance the convection of clean air when the clean air apparatus 4 is in operation. It can be seen that the fan 32 is mounted on a support, with the fan 32 suspended above the clean air inlet 42 and outlet 43.
In the invention, the setting requirement of the condensing device 3 ensures that the temperature in the smoke box 1 is kept as uniform as possible, on one hand, the air is mixed by the fan 32, and the most important thing is to keep the temperature above the aluminum plate 63 as uniform as possible through the condensing pipe 31, so that the problems that the local cooling is not enough and the local temperature is too low are avoided.
Therefore, the installation and commissioning method of the condensation device 3 of the present invention comprises the following steps:

Before the cooling debugging is carried out, moisture in the building where the aluminum plate is located needs to be removed, so that condensed water is prevented from being collected on the surface of the condensation pipe 31 and affecting other experimental equipment. Specifically, before the condensing unit is turned on for cooling, all the openings of the concrete building 6 are closed, and the inside of the concrete building 6 is dehumidified by the air conditioner. And (3) after the dehumidification operation is carried out until the hygrometer displays that the humidity in the concrete building 6 is less than 10%, starting a condensing unit for refrigeration and cooling, thereby starting formal debugging work, and the steps are as follows:

In this step, if the opening value of the valve after the opening is increased by a% is greater than 100%, the valve cannot be adjusted in the large direction any more, and the valve is kept at the maximum opening of 100%; similarly, if the value of the opening after the valve opening is decreased by B% is less than 1%, the valve opening is maintained at 1%, and the valve does not need to be completely closed. When the above extreme situation occurs, it is indicated that there is a problem in the layout of the condensation duct 31, and it is necessary to perform the debugging work again after readjusting the installation position of the condensation duct 31.
And repeating the process, measuring the temperature and adjusting the opening of the valve until the difference value between the temperature and the average value is less than 5%.
And the whole condensing device is installed and debugged.
