摘　　要：设计研究了一种蒸发冷却与半导体制冷相结合的分体式蒸发空调器，探讨了其原理及三种运行模式。总结出该分体式蒸发空调器的主要设计步骤。对样机进行了实验，得出了该分体式蒸发空调器的出水、出风温度。结果表明，室外机出风温度高于室外湿球温度3-4℃。室外机出水温度低于室外湿球温度1-2℃，经过半导体制冷再次温降后，可低于室外湿球温度4-5℃。依据实验结果，结合气象数据，计算得出该分体式蒸发空调器在我国288个城市的出风、出水温度结果。计算得出，该分体式蒸发空调器可在我国西北地区等高温低湿地区广泛采用，适用率超过90％。A split evaporative air conditioner of evaporative cooling and semiconductor refrigeration was designed. Principle and three modes of operation were discussed, and the design step of split air conditioner was summarized. The water and air temperature of split air conditioner were tested with the experimental prototype. The results show that the air temperature of outdoor unit is 3-4 ℃ higher than outdoor wet bulb temperature. The water temperature of outdoor unit is 1-2℃ lower than outdoor wet bulb temperature. After decreasing by semiconductor refrigeration again, it can be 4-5 ℃ lower than the outdoor wet bulb temperature. According to the test results, com-bined with meteorological data, the air and water temperature in 288 cities in China was calculated . The calculated result shows that the split evaporative air conditioner is widely adopted in Northwest China and other dry areas. The applicable rate is over 90%.
