Dust associated microorganism heat treatment characteristics and inactivation dynamic model in an air conditioning system

Taking the dust associated microorganisms in the air conditioning system as the object, investigates the survival situation in different temperature and thermal treatment time. The results show that the microorganisms in the dust reduce significantly after 10 minutes thermal treatment above 50 ℃. Through the data fitting with the Origin software, establishes the inactivation dynamic model of microorganisms at different temperature, which can provide a theoretical basis for the microbial contamination research.
