Difference between Clean Workshop and General Air Conditioning Workshop
The difference between clean workshop and general air-conditioning workshop is mainly based on the purpose, means, air supply, indoor pressure, maintenance management, capacity consumption, control of people's access and so on.
Different purposes: General air conditioning plant is to control temperature, humidity, wind speed, air composition, etc. In addition to the parameters of air-conditioning plant, the focus of clean workshop is to control the concentration of particles in the air and maintain cleanliness.
1: Different purposes
2: Different filtering methods
Filtration means are different: general air conditioning plant uses coarse, medium-effect filtration and heat and moisture exchange equipment; In addition to the use of air-conditioning plant means, the clean workshop should also carry out high-efficiency and ultra-high-efficiency filter filtering, and sterilize and disinfect the living particles in the air, so as to ensure the clean air of the clean workshop.
Different air supply: general air conditioning plant cooling 8-10 times / H ventilation, constant temperature room 10-15 times / H ventilation; One-way flow clean workshop 400-600 times / H ventilation, non-one-way flow clean workshop 15-60 times / H ventilation, air supply is much larger than the general workshop.
3: Different air supply
4: Different pressure in workshop
Pressure in workshop is different: there should be positive pressure in general air-conditioning plant, but it is not an important indicator; In the clean workshop, there must be positive pressure to prevent the infiltration of external dust and the escape of internal pollutants, which will affect the quality of products. For the sake of safety, negative pressure should be maintained to ensure the normal operation of the clean workshop in three aspects.
5: Maintenance management is different
Maintenance management is different: general air-conditioning plant periodic detection of temperature and humidity on it; In addition to temperature and humidity monitoring, the cleanliness of clean workshops should be tested regularly, and the testing requirements are strict.
6: Energy consumption is different
Energy consumption is different: refrigeration capacity of general air-conditioning plant is 100-200W/m2, power consumption is 50-100W/m2; refrigeration capacity of clean workshop is 400-1200W/m2, power consumption is 150-1500W/m2, which is much higher than that of general air-conditioning plant.
The control of people's entry and exit is different: general air-conditioning plant has no special control means for people's entry and exit; When entering and leaving the clean workshop, the staff must change shoes, change clothes, blow shower and sometimes shower. When entering the clean workshop, the goods should be cleaned and tested, and the flow and logistics should be separated, so that the pollution can be separated and the pollution can be prevented.
