Innovative methods to improve efficiency existing types of shell-and-tube devices
Annotation
Article is devoted to the problem of increasing the efficiency of chillers through improved traditional types of devices, in particular shell-and-tube condensers and evaporators. Among the many ways of intensification of heat and mass transfer in the apparatus should allocate a method comprising the rational organization and distribution of the working fluid flow in the cavities and channels of heat exchangers. The correct organization of flows, for example, working substances, leads to increased heat exchange, which in turn improves energy and weight and dimensions of devices. In result, it becomes possible not only to reduce metal, but increase the energy characteristics of the machine.
