PURPOSE:To enable a solar heat collector to be used for two different purposes, by providing both a passage for heating a refrigerant such as a Freon and a passage for heating water in the same apparatus. CONSTITUTION:A heat-collecting plate 4 is provided in a casing 1 which is covered by a sunlight-transmitting body 2 on the upper surface thereof and is provided with a heat insulator 3 at the lower surface thereof. Two independent passages 5, 6 provided with inlets 7, 8 and outlets 9, 10, respectively, are alternately placed in parallel to each other on the heat-collecting plate 4. One of the passages 5 is used as a passage for heating the refrigerant such as a Freon, while the other 6 is used as a passage for heating water. |
