<p><P>PROBLEM TO BE SOLVED: To provide a heat transport system efficiently using solar heat which is natural energy, a water supply system, a building environment control system for heating and air-conditioning, hot water supply, and the like, and a cooling device for electronic devices or the like. <P>SOLUTION: When solar heat is applied to a heat collecting plate 101A, an operating fluid evaporates at a low temperature and moves as steam to a header 102B since the interior of the device is decompressed by a vacuum pump 105H. A bumping phenomenon occurs within a heat collecting plate copper pipe, and liquid and steam pushed out by the liquid move to the header. The liquid circulates from a header lower part to a heat collecting plate inlet, and the steam moves from a header upper part to a condenser 103C and is condensed by cooling water controlled in temperature in a circulating constant temperature vessel 104D. A condensate moves again to the heat collecting plate inlet, and the liquid is circulated. In this system, noncondensed gas in the device is exhausted, and the evaporation temperature of the operating fluid can be lowered close to the environmental temperature. Since the operating fluid is circulated in a comparatively low temperature state, heat loss to environment can be suppressed. <P>COPYRIGHT: (C)2004,JPO</p> |
