Method of controlling relative humidity in gaseous sterilizers
Abstract
Abstract D R A W I N G A METHOD AND APPARATUS FOR CONTROLLING RELATIVE HUMIDITY IN A GAS STERILIZER. THE STERILIZER INCLUDEDS A CLOSED EVAPORATOR AND CONDENSER SYSTEM WHEREIN THE EVAPORATOR IS LOCATED INSIDE AND THE CONDENSER IS LOCATED OUTSIDE THE STERILIZING CHAMBER. THE CLOSED SYSTEM CONTAINS A FLUID HAVING A BOILING POINT SUBSTANTIALLY EQUAL TO THAT SATURATION TEMPERATURE OR DEW POINT WITHIN THE STERILIZER, WHICH CORRESPONDS TO THE DESIRED RELATIVE HUMIDITY AT THE OPERATING TEMPERATURE OF THE STERILIZER. SINCE THE SATURATION TEMPERATURE IS BELOW THE OPERATING TEMPERATURE OF THE STERILIZER, THE FLUID WILL BE CONSTATLY BOILING WHICH MAINTAINS THE EVAPORATOR AT THE DEW POINT TEMPERATURE SO THAT THE MOISTURE IN EXCESS OF THE AMOUNT NECESSARY TO PROVIDE THE DESIRED RELATIVE HUMIDITY WILL CONDENSE ON THE SURFACE OF THE EVAPORATOR. CONDENSATION AND REEVAPORATION OF THIS EXCESS MAINTAINS THE RELATIVE HUMIDITY WITHIN THE STERILIZER SUBSTANTIALLY CONSTANT.
