<p>PURPOSE:To permit to operate the device so as to obtain an objective heating capacity in accordance with the seasons at all times by a method wherein atmospheric temperature is detected at a predetermined time in morning to detect the objective heating capacity and a capacity control signal is outputted to a compressor so that the heating capacity of a heat collecting circuit becomes the objective heating capacity. CONSTITUTION:The inlet and outlet temperatures of a liquid heater 8 are being inputted into a main control circuit 13A from first and second temperature detectors 11, 12 and the heating capacity is being detected at all times in the main control circuit 13A by employing a temperature difference between them and a preset amount of flow of water. The season is decided by detecting atmospheric temperature by an atmospheric temperature detector 15 at a predetermined time in the morning to decide the objective heating capacity automatically and memorize it into the main control circuit 13A. In the operation of the day, the revolving number of the compressor 1 is controlled in accordance with the change of atmospheric condition so as to obtain the objective heating capacity.</p> |
