Abstract: A compression machine includes a refrigerant condenser, an expansion device, a refrigerant evaporator, a first compressor and a second compressor. Each compressor is arranged to receive lower pressure refrigerant vapor from the evaporator and to deliver higher pressure vapor to the condenser independently of the other compressor. The first compressor operates when the compression machine is operating in a first duty mode, for example a water-cooling mode. The second compressor operates when the compression machine is operating in a second duty mode, for example one of a water-heating mode or a brine cooling. The first compressor is selected for optimal performance in the first duty only and the second compressor is selected for optimal performance in the second duty mode only.

Abstract: A variable frequency drive system including an alternating current electrical power source, an alternating current motor and a variable frequency drive connected to the power source and the motor. The variable frequency drive provides electrical power to the motor, and includes an active rectifier to convert a first alternating current from the power source to a direct current and an inverter to convert the direct current to a second alternating current. A variable frequency drive output voltage is greater than a variable frequency drive input voltage, compensating for the motor apparent current. A method of electrical power conversion includes urging a first alternating current from a power source to a variable frequency drive. The first alternating current is converted to direct current via an active rectifier of the variable frequency drive, and the direct current is converted to a second alternating current via an inverter of the variable frequency drive.

Abstract: A dual refrigeration circuit watercooled chiller has its respective evaporators and condensers interconnected by waterboxes such that the first circuit tubes discharge into the respective waterbox and the flow of water then passes from the respective waterboxes to the respective evaporator/condenser tubes of the second circuit. Instrumentation is attached to the waterboxes to enable the measurement of the leaving temperature differential to provide improved control. Since the first and second circuit tubes are separate and independent, both serviceability and flexibility in design are substantially enhanced.
