INDoor AIr QuAlIty In another approach, application software available from the UV system supplier can be integrated with the OEM’s manufacturing software. The shop order will then select and add the proper UV equipment to the manufacturing bill of materials and production plans. A third approach, one taken by a large OEM, is to stock a modest inventory of modular UV components. Then, when an order is received, a UV software program is run to specify the UV equipment required. The UV parts are delivered to the appropriate point on the assembly line and the stock replaced as necessary. application is the Honeywell line of UV products for residential central HVAC systems. The UV appliance has been designed to install easily and to integrate with their control systems. Logic has been incorporated in the UV appliance to control the duty cycle of the UV appliance and thus optimize lamp life. In addition, the home control system warns the user when lamp replacement is recommended, just as it does with filter changes. As this development suggests, the growing application of UV equipment into HVAC/R systems has led more OEMs to consider the wisdom of incorporating the UV equipment, by design, during assembly of the system. In the controlled factory environment, they can provide optimal installations that will maximize the benefits of UV, while reducing or eliminating safety and material concerns. < For more information, enter . . . . . . . . . . . . . . 311 or email: sales@uvdi .com rEFlECtIVIty For VArIouS MAtErIAlS Around the wavelength of of 253.7 nanometers Material Aluminum - untreated surface Aluminum - treated surface Aluminum - sputtered on glass Aluminum paint Stainless steel Tin plate Magnesium oxide Calcium carbonate New plaster White baked enamel White oil paint White water paint Zinc oxide paint Galvanized Sheet Metal uV reflectance range % 40 60 60 89 75 85 55 75 25 30 25 30 75 88 70 80 55 60 5 10 5 10 10 35 4 5 50 64 MIN MAX MIN MAX MIN MAX MIN MAX MIN MAX MIN MAX MIN MAX MIN MAX MIN MAX MIN MAX MIN MAX MIN MAX MIN MAX MIN MAX Average % 50 74.5 80 65 27.5 27.5 81.5 75 57.5 7.5 7.5 22.5 4.5 57 residential success To date, a good portion of the OEM systems incorporating UV have been for large commercial systems. However, UV equipment is quickly gaining popularity in residential systems. Several OEMs currently offer UV appliances for residential equipment. One particularly successful table 1. Reflectivity of various materials. Your One Global Source for Innovation A. O. Smith is pleased to introduce the patented PAX Fan. The PAX Fan is uniquely designed to model the efﬁciency of ﬂuid ﬂow in nature. When attached to an A. O. Smith motor, the resulting system is more efﬁcient and quieter than traditional motor and fan combinations. A. O. Smith also provides next level features such as mounting bracket and wiring harnesses to increase efﬁciency on the assembly lines. Take advantage of the latest innovations in airmoving technology to reduce evaporator and condenser fan power consumption and noise. Contact A. O. Smith to learn more about how we can reduce power consumption, noise and assembly costs in your refrigeration system. www.aosmithmotors.com 531 N.
