PURPOSE: To utilize the solar heat properly by judging the advantage of utilizing the solar heat, based on weather conditions and the temperature of a solution in a generator, and thereby controlling a heat collecting pump.
CONSTITUTION: The solar heat utilizing abosrption type refrigerating machine is consisting of a heat collector 1, a heat accumulating tank 2, the heat collecting pump 7, the absorption type refrigerating machine 3, an air conditioner 4, a cooling tower 5 and an auxiliary heat source 6. A solution temperature signal is inputted into a control means 11 by measuring the temperature of the solution in the low temperature generator 3b in the absorption type refrigerating machine 3 by a liquid temperature meter 8 and a solar heat collecting amount is estimated based on the signals of a sunshine amount meter 9 and an atmospheric temperature meter 10, thereby deciding whether the solar heat is to be utilized or not and controlling the heat collecting pump 7.
