According to statistics, refrigeration and air conditioning equipment accounted for 30% of global energy use which was the largest part of energy consumption. Therefore, this study aimed to apply moisture-absorbing and quick-drying fabrics, which improving performance and energy saving in the system is due to removing heat and reducing entropy generation in the compression process, Experimental method includes fabrics’ evaluation and room air-conditioner performance testing. Fabrics’ evaluation used 8 different fabrics for dropping, moisture diffusion capacity, wicking method, and moisture drying rate to derive the best fabrics, which passed the evaluation of moisture-absorbing and quick-drying as the coating material of compressor. Room air-conditioner performance testing was mainly tested with the performance of R410A air conditioner for different ambient temperatures (30°C, 35°C and 40°C) and indoor loads (1200W, 1600W, 2000W). According to the result, it showed that using the profiled fabrics as blended material has better effect in moisture-absorbing and quick-drying. In the room air-conditioner performance testing, the compressor irreversible rate reduced 40%, COP improved about 20.7%, and EPC improved about 11.06% in the new air conditioner. The above results showed that with the coated fabrics could enhance cooling effect of compressor, and truly improved the performance of the overall system, and thus achieved energy saving efficiency.
