It is divided into three types: upper exhaust type, lower exhaust type and upper and lower simultaneous exhaust type. The wind speed in the work area is uniform. The lower exhaust type should be adopted for the cold process, the upper exhaust type should be adopted for the hot process, and the exhaust outlets can be set up and down to adjust with the change of the heat generation in the cabinet for the process of unstable heat generation. The ratio of the upper and lower exhaust air volume to obtain a uniform wind speed.
According to the type of air intake, it is also divided into three categories. It is called the full exhaust type, which is a type that is widely used.
When it is installed in a room with heating or temperature and humidity control requirements, in order to save heating and air conditioning energy consumption, the method of taking the supply air from the outside and circulating it in the cabinet and exhausting it to the outside is called the supplementary air type.
The other is the variable air volume control type. Ordinary constant air volume systems need to manually adjust the air valve with fixed blades, adjust the exhaust air volume, and reach the desired surface wind speed when the valve is adjusted to a certain angle. Variable air volume control is to change the air volume to reach a given surface wind speed by adjusting the sensor of the valve. Of course, the standard type has low cost and high variable air volume cost, which is suitable for occasions that require high precision.
According to the status of use, it can be divided into integral lower part open type, floor-standing type, two-sided type, three-sided glass type, desktop type, conjoined type, and radioactive experiments and synthetic experiments designed according to different experimental use needs. Dedicated for perchloric acid experiment.
