The paper analyzes the various factors that cause failure of refrigerator evaporator. The refrigerator evaporator failure spectrum is constructed through qualitative analysis of the fault tree system after building a corresponding fault tree system. There is an analysis procedure of fault tree system based on computer aided fault tree analysis system (CAFTA).

In this study, we investigate the linear and weakly nonlinear stability of a liquid film flowing down an inclined plane with insoluble surfactant. First, evolution equations thickness surfactant concentration are derived using long-wave expansion method at moderate Reynolds number (0 < Re ≤ 20). The flow is examined normal-mode method, criterion critical Rec obtained. results reveal dest...

• A new test rig based on the falling film spray technology was set up. Four different designs such as empty tower, plates were proposed. The heat and moisture recovery performance from flue gas testedsystematically. effects of control parameters water–air ratio inlet air temperature transfer effectiveness examined. Increasing or decreasing can improve for all cases. discharge is rich in water ...
