CONTROL DEVICE AND CONTROL METHOD FOR BLEED DEVICE

The purpose of the present invention is to achieve stable operation when using a low pressure, low GWP refrigerant. In the present invention, a control device (16) is provided with an estimation unit (31), a determination unit (32), and an activation control unit (33). The estimation unit (31) estimates the amount of air entering using a degree of influence of air entering, which represents the ease with which air enters determined by the structure of the chiller, and a variable obtained by a function including pressure as a parameter. The determination unit (32) determines whether a total value for the amount of air entering is greater than or equal to a preset tolerance value. The activation control unit (33) activates a bleed device when the total value of the amount of air entering is equal to or greater than the tolerance value.
