| Abstract: | The influences of evaporator＇s performance on water chiller＇s performance are analyzed. Based on it, the key technologies of falling-film evaporator are discussed. Meanwhile, the heat transfer coefficient and oil concentration in the falling-film evaporator are experimentally sludied and compared with flooded evaporator. The results show that when the fluid supply from the distributor is sufficient,the falling-film evaporator has bet- ter performance, which has higher heat transfer coefficient, large oil concentration, etc. |

| Keywords: | water chiller evaporator full falling-film flooded heat transfer coefficient oil concentration |
