Abstract
PURPOSE: To reduce power consumption of a water circulating device and to reduce the peak current at the starting time by changing the number of poles of a water feeding pump motor to drive the motor when controlling the quantity of water responsive to the variation of the load in the water circulating system of an air conditioning facility.
CONSTITUTION: When the quantity of water responsive to the variation in a load of a water circulating system for an air conditioning facility is controlled, a pole change motor is used as a motor for driving a water feeding pump, and the number of poles of the motor can be increased or decreased in response to the variation in the load of the system. The power consumption of the case that 4P-6P pole change motor is, for example, it is reduced in the range designated by the shaded adrea in Figure as compared with the method of controlling the number of conventional pumps.
