The difference between air purification system and general central air conditioning system
There are many friends can not tell the difference between the general air conditioning system and the purification air conditioning system, so today we summed up a few points, I hope to help you.
1. in the aspect of air filtration: the general central air conditioning system adopts the first stage coarse effect filter, the most adopts the two-stage filter, and the filter is not located at the end of the tuyere, and there is no air filter above the sub-efficiency. Therefore, the indoor dust concentration of the two systems is at least tens of times worse.
2. airflow organization: the general central air conditioning system is a turbulent flow form, with smaller ventilation as far as possible to improve the indoor temperature and humidity field uniformity, while purifying the air conditioning system is to limit and reduce the diffusion of dust particles, Reduce secondary airflow and eddy current.
3. indoor pressure control: clean room (area) of purifying air conditioning system requires positive or relative negative pressure, minimum pressure difference is more than 5~10 Pa, which requires supplying certain supplementary fresh air volume or giving certain exhaust air. The general central air-conditioning system has no clear requirements for indoor positive pressure.
4. air volume energy consumption: the general central air conditioning system has only 10/ h air exchange times, and the purification air conditioning system should be more than 12/ h, or even more than ten times the general central air conditioning system. The energy consumption per square meter of purifying air conditioning system is 10~20 times more than that of general central air conditioning system.
5. the investment cost of purifying air conditioning system is much higher than that of general central air conditioning system.
