PURPOSE:To smoothen the retrieval of operating liquid from a liquid reserving tank to a generator by a method wherein second nonreturn valve is provided on a return tube between a liquid absorbing tank and the liquid reserving tank. CONSTITUTION:When the operating liquid 12 is retrieved from the liquid reserving tank 7 to a collector 1 through an opening and closing valve 10 being opened, the operating liquid 12 is retrieved once into the liquid absorbing tank 14 and is retrieved from the liquid absorbing tank 14 into the collector 1 even under the closed condition of the opening and closing valve 10 whereby a time for retrieving the operating liquid is shortened and the average flow amount of the operating liquid 12 is increased. On the other hand, the operating liquid 12 flows from the liquid absorbing tank 14 into the collector 1 to supplement the same liquid 12, which flows out of the collector 1 through a sending pipe 5 under the closed condition of the opening and closing valve 10, therefore, dry-out of the heat collecting pipe of the collector 1 may be prevented and the performances of heat transfer and heat collection may be improved. |
