In order to ensure the clean environment of pharmacy, a clean air conditioner is needed to provide clean air supply for the pharmacy. Due to the pharmaceutical particularity, the clean air conditioning system usually has five working conditions to meet the production requirements. The five operating conditions are: normal operation condition, disinfection exhaust operation condition, on-duty operation condition and shutdown condition. Under these different conditions, the amount of fresh air required by the system is different. In order to achieve the goal of different fresh air volumes under different working conditions, it is a common practice in the industry to add an adjustable electric valve on the fresh air pipeline, and adjust the fresh air volume by adjusting the opening of the electric valve, i.e. increasing or decreasing the resistance (see fig. 2).
When the fresh air volume difference under different working conditions is not large, the traditional mode can meet the requirement of fresh air volume adjustment. However, when the fresh air volume difference under different working conditions is large, the requirements cannot be met through the adjustment of the electric valve due to the limitation of the adjustment range and the adjustment precision of the electric valve.
The required fresh air volume in normal operation is as follows: 3700m3The required fresh air volume during the operation on duty is as follows: 1000m3H, the required fresh air quantity during the operation of disinfection and air exhaust is as follows: 12000m3H is used as the reference value. The change range of the fresh air volume is as follows: 1000 to 12000m3H, since the maximum value is 12000m3And h, in order to meet the fresh air volume at the moment, the valve body with the larger pipe diameter is selected as the electric valve. And only 1000m is needed in duty working condition3The electric valve is required to be closed to a very small opening degree at the moment of the fresh air volume,/h, but when the electric valve is in a very small opening degree, air vortex is easily caused, and the fresh air volume is difficult to stabilize. The fluctuation of the fresh air volume directly causes the fluctuation of the pressure of the clean air-conditioning area, which is not allowed by the acceptance standard of the clean room.
The utility model provides a fresh air control device for a purification air-conditioning system under different working conditions, which is used for solving the problem that fresh air fluctuates due to adjustment of a large-diameter electric valve when the fresh air quantity difference under different working conditions is large, and further the problem that the pressure of a clean room fluctuates.
