Publication number: 20210369890Abstract: An antimicrobial lighting system is used to reduce microbial growth on surfaces in or on air conditioning and/or heating equipment. In some examples, antimicrobial light within one or more antimicrobial wavelength ranges is applied to inactivate one or more microorganisms on target surface(s) within or on a packaged terminal air conditioner (PTAC). The antimicrobial light may include light within a first antimicrobial wavelength range and/or light within a second antimicrobial wavelength range. The antimicrobial lighting system may include an array of individually controllable antimicrobial light segments. An array controller may individually control activation of the one or more antimicrobial light segments based on the status information or commands received from a PTAC controller or from an external computing device.Type: ApplicationFiled: May 20, 2021Publication date: December 2, 2021Inventors: Peter Andrew Voss, Paul Dominic Christian, Teresa C Podtburg, Paul R.

Patent number: 8246906Abstract: A method for antimicrobial treatment (e.g. antimicrobial treatment of food packaging and equipment) comprising applying to microbes a composition containing a diluting solvent (e.g., water), an antimicrobially-active solvent having a density different from the density of the diluting solvent, and an optional cosolvent, surfactant, or additional antimicrobial agent, wherein the amount of antimicrobially-active solvent or additional antimicrobial agent is sufficiently high and the amount of cosolvent or surfactant is sufficiently low so that the composition will provide greater than a 1-log order reduction in the population of bacteria or spores of Bacillus cereus within 10 seconds at 60° C. Preferred methods of the invention employ compositions containing an additional antimicrobial agent such as peroxyacetic acid. Compositions for use in the method can be prepared as concentrates, and used full strength or in diluted form.Type: GrantFiled: February 9, 2009Date of Patent: August 21, 2012Assignee: Ecolab USA Inc.Inventors: Robert D. P. Hei, Guang-jong J. Wei, David A. Halsrud, Kim R. Smith, Teresa C. Podtburg
