摘要(Abstract)：

设计制作了蒸发冷却与半导体制冷相结合分体式蒸发空调器的试验样机,在标准的空调焓差检测实验台上,模拟室内外侧空气温湿度,在室外侧干球温度34℃,湿球温度18~23℃之间的工况下,对该分体式蒸发空调器的冷水的温度、流量,冷风的温湿度进行了试验。结果表明,该分体式蒸发空调器在室外工况湿球温度20℃以下不开启半导体制冷装置即可满足需要;配合4组半导体制冷装置即可满足室外工况湿球温度23℃时需要,同时也保证了半导体制冷装置较高的能效比;得出了该分体式蒸发空调器的最佳气水比为2,亚湿球效率为110%。进而为分体式蒸发空调器的优化设计与产品开发奠定基础。
Experimental prototype of split evaporative air conditioner of evaporative cooling and semiconductor refrigeration is developed.Simulating the outdoor and indoor air,it is under operating conditions that the outdoor dry-bulb temperature is 34℃,wet-bulb temperature is between 18℃ and 23℃.The water temperature and flow,air temperature and humidity of split air conditioning is tested.The results shows that it doesn't need semiconductor refrigeration device under the wet-bulb temperature of 20℃ in outdoor conditions.To tie four groups semiconductor refrigeration device,it can meet the temperature of water which system needed under wet-bulb temperature of 23℃ in outdoor conditions.Also it guarantees a higher EER of semiconductor refrigeration device.It obtains the best air-water ratio is about 2 and sub-wet bulb efficiency is about 110%.And thus lay the foundation for the optimization of design and product development for the split air-conditioning.
