摘要： A method is used for cleaning heat exchanger systems. The method is performed at a computer system having one or more processors and memory storing one or more programs configured for execution by the one or more processors. The method determines component percentages of a cleaning solution based, at least in part, on operational parameters of a heat exchanger system. The operational parameters include chemical composition of fluids passing through the heat exchanger system and operating temperatures of the fluids passing through the heat exchanger system. The component percentages of the cleaning solution include: (1) hydrogen peroxide, 2-90 wt. %; (2) a complexing agent, 3-30 wt. %; (3) water-soluble calixarene, 0.01-10 wt. %; and (4) water. The complexing agent includes a polybasic organic acid or a sodium salt thereof, or a derivative of phosphorous acid.

摘要： 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.

摘要： The invention relates to a method for evaluation of fouling of passages of a spacer plate (10) of a tubular heat exchanger (11), wherein first, second and third pressure sensors (31, 32, 33) are arranged, the method comprising steps of: (a) during a transient operation phase of the heat exchanger determination of a value over time of Wide Range Level NGL, from the measurements of the first and third pressure sensors (31, 33), and of a value over time of Narrow Range Level NGE, from the measurements of the second and third pressure sensors (31, 33); (b) determination of a value over time of Steam Range Level deviation ΔNGV, corresponding to the NGL from which a component representative of a variation of free water surface in the heat exchanger has been filtered, from the values of NGL and NGE; (c) comparison of the determined value of ΔNGV with a set of reference profiles ΔNGVi for said transient operation phase of the heat exchanger, each reference profile ΔNGVi being associated with a level of fouling so as to identify a target reference profile ΔNGVopt among the reference profiles ΔNGVi for said transient operation phase of the heat exchanger, which is that closest to the determined value ΔNGV. (d) restored on an interface (3) of the level of fouling associated with the identified target reference profile ΔNGVopt.
