The purification laboratory is a totally-enclosed environment, and the air in the indoor environment is continuously and circularly filtered through the primary, intermediate and high-efficiency filters of the air-conditioning air supply and return systems so as to ensure that suspended particles in the air are controlled to a certain concentration. The purification laboratory mainly has the main function of controlling the cleanliness, the temperature and the humidity of the atmosphere contacted with products (such as silicon chips and the like) so that the products can be detected and researched in a good environmental space. Clean laboratories are therefore also commonly called ultraclean laboratories, clean-class laboratories, etc.
Therefore, aiming at a purification laboratory or a laboratory with requirements on environmental pressure and other scientific research and production environment places, in order to maintain the environmental pressure, the air quantity difference between the environmental air supply and the air exhaust is maintained by adjusting and controlling the air supply air valve and the air exhaust air valve of the environment. The adopted technical means are two, one is that the air supply and exhaust valve for adjusting the environmental pressure adopts a variable air volume air valve, the environmental pressure is collected through a set of active control system, and the variable air volume air valve is actively controlled in a closed loop mode through a P confirmation code algorithm, so that the environmental pressure is maintained within the design range. Because the control valve, the sensor and the control system which are invested by the technical means have higher manufacturing cost, most debugging personnel cannot bear the construction cost. The other air supply and exhaust valve for adjusting the environmental pressure adopts a manual air valve, and manually adjusts the air supply and exhaust volume of the environment through manpower and a simple differential pressure detection tool, so that the environmental pressure is kept in a design range. The second technical method has low initial investment, and is low in efficiency because the adjusting valve operation place and the indoor environment are not on the same operation level any more in projects with more pressure requirement environment construction, and the debugging process consumes time and manpower, and requires multiple persons to cooperate to complete the environment pressure debugging work.
