MEDIUM VOLTAGE STARTER FOR A CHILLER UNIT
First Claim
1. A chiller system comprising:
- a compressor, a condenser and an evaporator connected in closed refrigerant loop, the compressor, condenser and evaporator being integrally mounted to form a chiller system unit;
a medium voltage motor connected to the compressor to drive the compressor, the medium voltage motor being mounted on the chiller system unit;
a control panel to control operation of the chiller system, the control panel being mounted on the chiller system unit;
a single starter box comprising all starting components used in starting and operating the medium voltage motor, the starter box being mounted on the chiller system unit adjacent to the medium voltage motor; and
wherein the starter box is mounted on the chiller system to permit a close coupling of electrical connections between the starter box and the medium voltage motor without a power conduit connection between the starter box and the medium voltage motor.

Abstract
A single medium voltage starter box is mounted on a chiller unit with the other components of the chiller system. The starter box can be positioned on the chiller system unit to permit the starter box to be close coupled to the motor, and specifically to the main motor lead exit hub without the need for any power conduit connections between the starter box and the motor. In addition, the starter box also does not require any control interface and receives controls from a control panel. A short conduit connection between the control panel and the starter box is used to provide the necessary connections between the control panel and the starter box.
