PROBLEM TO BE SOLVED: To solve problems in a cogeneration system of a conventional Rankine cycle engine wherein the size is increased, the cost is increased, and the increase of performance is hard since a high temperature heat exchange part (heater) heating a working medium for driving and a water heating part (water heater) for generating hot water by exhaust heat are formed separately, and particularly excessive heat insulation is applied therearound to prevent the loss of heat radiation from these devices to the outside from occurring. SOLUTION: In this system, the heater 10 is installed in a hot water device to minimize heat loss, and an efficiency is improved, device systems are facilitated, and cost is reduced. A heat medium provided from a high temperature heat source is introduced into the heater from the outside to heat and evaporate mainly a working fluid in a liquid state. To properly control the temperature, the periphery of the heater is simply insulated or the inflow state of the heat medium is controlled. COPYRIGHT: (C)2007,JPO&INPIT
