PURPOSE:To uniformly supply cooling medium liquid to an air heat exchanger consisting of a plurality of cooling pipes and to prevent the cooling medium liquid from returning back, by supplying the cooling medium liquid to part of cooling pipes by the intermediary of a distributor. CONSTITUTION:At a rising time, a cooling medium liquid is supplied to all cooling pipes in the cooling part 4 of a heat exchanger 1 from expansion valves 7, installed in cooling medium liquid feeder pipes 5a and 5b, by the intermediary of a header 3. On the other hand, during the time of steady operation and at the time of load fluctuation, the cooling medium liquid is supplied to part of cooling pipes in the cooling part 4 by the intermediary of expansion valves 7 installed in each cooling medium liquid feeder pipe 5c-5n, distributors 8, and branch pipes 9. By this method, each cooling pipe is prevented from uniform performance of evaporation, so that return back action of the cooling medium liquid is prevented. |
