Abstract
PURPOSE: To control the width of the variation of water temperature in small value by the quantity of water possessed, which can be ensured in response to the conditions of a locations where a unit is installed, by mounting a temperature detecting means into a water piping system.
CONSTITUTION: A sensor 25 for detecting water temperature is mounted to a water piping 24, and the output signals of the sensor 25 input the temperature of water possessed to a micro-computer 8 through an AD converter 23. Auxiliary relays 26, 27 are connected to the output side of a keyboard 8. When electricity is conducted to the auxiliary relay 26, a condition that water temperature reaches a set point is brought, and an electromagnetic contactor for Number One compressor is de-energized. When water temperature reaches the next set point, electricity is conducted to the auxiliary relay 27, and Number Two compressore also stops. Thus, the control of water temperature suitable for the quantity of water possessed, which is decided according to the conditions of execution, can automatically be controlled, the width of the variation of the water temperature of a unit can be lessened and the operation of the unit can be caontrolled efficiently and stably.
