Abstract
PURPOSE: To improve operability by a method wherein a large capacity pump and a small capacity pump are connected in series, the small capacity pump being provided with non-return valves in series and parallel and an operation of a warm water heating machine is controlled by signals from pressure switches provided at discharging sides of these pumps.
CONSTITUTION: Warm water as a heat source is reserved in an open system warm water receiving rank 1 and is sent by pressure of a main pump 3 to a heat exchanger 10 through a non-return valve 2, thereafter, is sent to a fan convector 6 after it is heated in the heat exchanger 10. A pump for a signal also is operated simultaneously at this time. Here, when a valve 9 associated with an operating switch for a fan of the fan convector 6 is closed totally and a sum of pressures of the pumps 3, 4 is exceeding a preset pressure of a pressure switch 7, the switch 7 is opened and both of the pumps 3, 4 and a warm water heating machine are stopped. Next, when the fan convector 6 is operated, the valve 9 is opened, the pressure switch 7 is closed and the pumps 3, 4 as well as the heating machine are bugun to operate.
