Abstract:
A centrifugal chiller, comprising;an evaporator shell; a condenser shell extending above the evaporator shell and being horizontally off center relative thereto, wherein the evaporator shell and the condenser shell provide a combined width of between 5 feet and 8.5 feet; a centrifugal compressor supported by the evaporator shell to provide a combined height of between 6 feet and 12 feet, wherein the centrifugal compressor is in fluid communication with the evaporator shell and the condenser shell; a motor connected to the centrifugal compressor and having a rated voltage of at least 2,000 volts, wherein the motor has sufficient power to enable the centrifugal chiller to create at least 300 tons of cooling; a reduced-voltage starter being electrically coupled to a plurality of motor leads extending from the motor and being supported by at least one of the evaporator shell, the condenser shell, and the motor; and a full-voltage starter being electrically wired to the reduced-voltage starter and being supported by at least one of the evaporator shell, the condenser shell, and the motor; whereby the evaporator shell, the condenser shell, the centrifugal compressor, the motor, the full-voltage starter and the reduced-voltage starter can be transported as a single unit.
