On the Performance and Efficiency of Surface Air Cooler Working under High Temperature and High Humidity Condition

Surface air cooler is widely used in refrigeration, conditioning, chemical dehumidification, and other related fields. Nowadays, the application of surface has been mature under standard working conditions, more research carried out on its application. However, when conventional coolers are directly high temperature humidity conditions (the higher than 30°C, both ratios 20 g/kg dry air), or with strict dehumidification requirements, expected results often not achieved. Therefore, taking as an example, performance efficiency investigated specifically this paper. Based above model experiment, influence operation parameters heat mass transfer analyzed. At same time, change law capacity, performance, a specially investigated. Results proved that (34.8°C, 23.03 lower head-on wind velocity could realize deeper humidification effects effectively, while water showed fewer impacts. As shown increased to 1.2 m/s, dropped 1.06 ratio at outlet reduced 8.88 heat-transfer reached 0.778; however, 2.5 m/s rose 13.17 only, merely 0.572. In conclusion, paper established accurate effective mathematical for analyzing characteristics which provides reference development design special conditions. More importantly, conclusion also points that, different from adjusting strategy reducing speed best This only conducive promoting achieve better effect but can effectively improve cooler.
