    • PROBLEM TO BE SOLVED: To provide a solar heat collecting system wherein a heat medium such as water can be efficiently circulated without using motors. SOLUTION: A plurality of heat collectors 12 each having a heat collecting tube 12a, through each of which a heat medium passes, are provided, and an inlet port, into which the heat medium to be heated flows, is provided at an end of a heat collecting tube 12a, while an outlet port, from which the heated medium flows out, is provided at the other end of the tube 12a. Each of the collectors 12 is oriented vertically or approximately vertically with its outlet port being located above, while the inlet port is located below. A heat storage tank 14 is provided to store the heat medium heated at the collector 12, and the tank 14 is disposed so that the outlet port of the collector 12 is located at a level below the liquid level of heat medium in the tank 14. The outlet port of each collector 12 is connected to a first inlet port located slightly below the liquid level of the medium in the tank 14 so that the collector 12 communicate with the tank 14 through a first tube. The inlet port of each collector 12 is connected to a first inlet port located below the tank 14 so that the collector 12 communicates with the tank 14 through a second tube.

    • PURPOSE:To obtain a heat exchanging system using temperature difference between a sunny place and a shade by a method wherein heat carrier is condensed by a condenser located on a north side and a tank where the condensed heat carrier is stored and a connecting pipe which connects the tank and fine tubes are provided. CONSTITUTION:Heat carrier in fine tubes 4 located on a south side receives the sunlight radiation and is heated up to 80 deg.C, for example. Then, the heat is released through a heat-radiation surface 5 to heat a floor, for example. The heat carrier after releasing heat is condensed by a condenser 6, stored in a tank 8 through a connecting pipe 7, enters the fine tubes 4 through fine pipes 9 and is heated again. In another words, the heat absorbed on the south side is carried by the heat carrier and consumed by a heat exchanger. In the drawing, a floor heater is a heat exchanger, and the floor is heated. In the condenser on the north side, the heat carrier is turned into liquid by using the low temperature in the shade, and returned to the tank 8 by gravity. A heat exchanging system using temperature difference is composed of this closed circuit without a driving pump.
