| Summary: | adhesion strengths of the droplets were found to be 590 for aluminum outdoor heat exchangers. The overall performance of bare aluminum, 34' for acrylic coated aluminum, and 24' for case test results were compared to tests that utilized coated coated aluminum surface, and an acrylic resin coated aluminum coefficient of performance of the heat pump. Overall, the condition, the coatings were within 2.4% of the base coil for cooling and heating mode conditions. The adhesion strength of could be applied thin enough, increased heating performance could be obtained from the heat transfer enhancement of the each test was analyzed. These tests were carried out for For frost/defrost testing conditions, it was generally found frequency of defrost cycles. Potentially, if the coating frost/defrost cycle times than the base coil. In general, investigated. The base case tests used a bare aluminum measure of adhesion strength. The adhesion strength was measured through a range of temperatures. At 1.1C the not significantly effect the integrated capacity, integrated on the performance of an air source heat pump were outdoor heat exchanger in the experimental setup. The base outdoor heat exchanger of a split system heat pump could be outdoor heat exchanger. parameters of the heat pump. For the cooling mode testing release from the surface quicker for silicone resin surface results of this study showed that hydrophobically coating the silicone coated aluminum. Hence, water droplets would surface were catalogued and compared. The angle at which the than for the other two surfaces. The coatings were not found than the base coil. During the heating mode, the coating did that the coated outdoor heat exchangers produced longer the defrost times were found to be less for the coated coils The effects of outdoor heat exchanger hydrophobic treatment the system EER, power consumption, and the system capacity. to have any detrimental effects on the cooling performance total system power consumption, or the integrated cyclic used to increase the heating performance by decreasing the water droplet released from the surface was used as the water droplets to a bare aluminum surface, a silicone resin |
