Technological optimization.Projecting design,as a de,represents itself the sequence of iterations with the purpose of detection of sizes of the heat exchanger satisfying to input definition of the area of heat change F.Further there is a necessity for creation of this surface with the help of that or diverse ribbed laminas,and also with allowance for of dimensional limitations.This purpose - essence of technological optimization of the heat exchanger.In the basis of algorithm of the program the calculation of group ("set") compact heat exchangers with different number of packets is utilised at identical low regimes of heat carriers.As criterion for selection of an optimum design the principle of equality of three dimensional sizes (form of an equilateral cube) will be used.In this case alongside with optimum costs of manufacturing of a heat-transport section,receive minimum costs of manufacturing of connective fitting pipes.
Thermal optimization.The technological optimization is relevant,but not by an along problem projecting design.In-particular there is opened a problem on an overall performance of the designed heat exchanger.Most generalized effectiveness criterion of the heat-exchange is its thermal efficiency:relation of an actual heat flow in the actual heat exchanger maximum theoretically possible in an ideal infinite countercurrent heat exchanger.In the bas of algorithm of the program the calculation efficiency of "set" of heat'exchangers is utiliseand also specialized calculation according to thermal efficiency of utilised ribbed laminas hot and cold channels.As creations of a thermal optimality there is used the principle Correspondence of efficiency of the heat exchanger from set" to computational (given efficiency,and also efficiency of utilised ribbed laminas.
