Abstract

PURPOSE: To provide an effective utilization of heat conducting area of a shell- and-coil type heat exchanger to be used in a cooling and heating hot water feeding device having a coolant compressor therein by a method wherein a corresponding length of each of the heat conducting pipes is made to be equal with each other.
CONSTITUTION: After the lengths of pipes of heat conducting coils 24-1W24-3 are made to be equal mechanically, coil diameters of the heat conducting coils 24-1W24-3 are made to be large in sequence in this order under a concentric relation and an equal pitch thereof, and the number of turns of the heat conducting pipe coils 24-1W24-3 are made to be decreased in sequence in this order so as to make equal in each of the corresponding coil lengths. Further, differences in axial lengths of coils caused by the number of turns of the coils are equally distibuted toward an axis of the coil in such a manner as an axial length of the coil 24-1 is made twice as that of the coil 24-3. Thus, resistances in the coil axis of the heat conducting coils are made to be equal and the coolant is equally distributed therefor, a performance of heat conducting operation in each of the heat conducting coils may effectively be provided.
