| Abstract: | According to Werkel's theory, sets up the heat and mass exchange equations inside a spray-type cooling tower without packing layer. Deduces an expression of COP. Calculates the COP of the tower under a working condition with numerical method. By way of the experiments, determines the performance curve of the tower. Based on the curve, regresses an experiential expression of the COP of the tower. |
