Abstract: A sealed induction motor for a chiller assembly is provided. The induction motor includes a stator, a rotor, and a shaft with a first end and a second end. The rotor and the shaft are configured to rotate relative to the stator. The induction motor further includes a first magnetic bearing assembly located proximate the first end of the shaft and a second magnetic bearing assembly located proximate the second end of the shaft. The first and the second magnetic bearing assemblies are configured to support the shaft. The shaft is coupled to a centrifugal compressor using a direct drive connection.

Abstract: A modular water based heating and cooling system for providing chilled or heated water to terminal devices in a building to heat/cool individual zones in the building. The system includes a flow control device in fluid communication with a riser chilled water supply line, a riser chilled water return line, a riser heated water supply line, and a riser heated water return line. The flow control device includes first control valves and second control valves. Terminal device supply lines extend from the flow control device and are connected to respective first control valves. Terminal device return lines extend from the flow control device and are connected to respective second control valves. The first control valves and the second control valves cooperate to supply required chilled water or heated water through the terminal device supply lines to terminal devices based on the cooling/heating requirements of the terminal devices.
