<p><P>PROBLEM TO BE SOLVED: To provide a heat exchanger which heats a heat collecting liquid of low temperature with high temperature efficiency while collecting heat energy of a heat source liquid of high temperature with a high rate. <P>SOLUTION: The heat exchanger for exchanging heat between the heat supply-side heat source liquid and a heat receiving-side heat collecting liquid flowing in the directions opposite to each other in two liquid passages partitioned by a thin partitioning wall of high heat conductivity, respectively, is operated in a defoaming operation mode for discharging bubbles in two liquid passages in starting an operation, and then operated in a heat exchanging operation mode exchanging heat between the heat source liquid flowing in a laminar flow state and the heat collecting liquid flowing in a laminar flow state. At this moment, flow rates of the heat source liquid and the heat collecting liquid are determined while considering a heat transferring area and an energy collection rate. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
