Summary

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 about 3-4 °C higher than outdoor wet bulb temperature. The water temperature of outdoor unit is about 1-2 °C lower than outdoor wet bulb temperature. After decreasing by semiconductor refrigeration again, it can be about 4-5 °C lower than the outdoor wet bulb temperature. According to the test results, combined with meteorological data, the air and water temperature in 228 cities in China was calculated. The calculated results show that the split evaporative air conditioner is widely adopted in Northwest China and other dry areas. The applicable rate is over 90%.
