PURPOSE: To utilize the solar heat properly by judging the advantage of utilizing the solar heat, based on weather conditions and the temperature of cool water from the absorption type efrigerating machine, and thereby controlling a heat collecting pump.
CONSTITUTION: The solar heat utilizing absorption 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. The temperature of the cool water from the refrigerating machine 3 to the air conditioner 4 is measured by a meter 11 and a cool water temperature signal is inputted into a control means 12 together with the signals of a sunshine amount meter 8, an atmospheric temperature meter 9 and an atmospheric humidity meter 10, in order to estimate a heat collecting amount and decide whether the solar heat is to be utilized or not, thereby controlling the heat collecting pump 7. The measurements of the cool water temperature and the atmospheric humidity may be omitted and assumed values therefor may be employed.
