Title

Test Results Of Energy Saving And Humidity Control Devices

Abstract

The Appliance Laboratory at FSEC/UCF conducts testing of products and HVAC concepts claimed to save energy. This article provides the results of three test projects: (1) Tests of a spray-on coating for AC condensers sold under the brand name Adsil, and claimed to save energy by increasing heat exchange of the condenser; (2) Tests of a compressor oil additive sold under the brand name PolarShield and claimed to save energy by increasing compressor lubricity and improving refrigerant side evaporator and condenser heat exchange; and (3) Tests of a unique desiccant/HVAC combination (Cromer cycle) claimed to increase humidity control in humid environments while saving energy over other dehumidification strategies. The third test is on a concept that is being developed for commercialization. The Adsil product showed statistically significant improvement of the EER of the air conditioner units after it was applied. The improvement ranged from zero improvement when added to a new unit, up to 11.9 percent savings on a degraded condenser estimated at 85 percent of its useful life. The Polarshield product showed no improvement in EER or energy savings in the three before/after tests. The third test showed a statistically significant reduction in performance and more energy use after the Polarshield was added. The Cromer cycle showed a doubling of the moisture removed by the test air conditioner and a reduction of the relative humidity in the space without a reduction in EER of the equipment. The results are promising and thus further effort toward commercialization is warranted. © 2003 Energy Engineering. All Rights Reserved.
