The performance characteristic of a variable-speed centrifugal chiller is different
from that of conventional fixed-speed centrifugal chiller. The variable-speed centrifugal chiller
has highest COP point in partial load (we call optimal load), which varies according to the
cooling water temperature. This optimal load can be easily calculated from the machine
characteristic of centrifugal chiller. In this paper, we report the calculation of optimal load and
the optimal operation method of heat source system using the optimal load.
