Model of the loss of efficiency of metal structures of the evaporator of refrigerating machine
The article is devoted to the development of a model of the loss of efficiency of a shell-and-tube evaporator with intra tube boiling of freon. It is established that the process of loss of the efficiency of the evaporator is associated with the development of local deformations of the heat exchange tubes caused by the freezing of coolant (water) in the radial gaps of the milling joints of the tubes with the tube sheet.
