Abstract
A chiller system includes: a chiller; a load; a feed pipe through which water flows from the chiller to the load; a return pipe through which water flows to the chiller from the load; a first controller that controls the chiller; and a second controller that outputs a chiller operating command to the first controller. The chiller includes a first sensor, a second sensor, and a third sensor. The first sensor measures an inlet water temperature of water flowing through the return pipe. The second sensor measures an outlet water temperature of water flowing through the feed pipe. The third sensor measures an outside air temperature at a chiller installation location. The first controller calculates a temperature range for the chiller based on an inlet water temperature, an outlet water temperature, and an outside air temperature, and then outputs the temperature range to the second controller.
