Abstract:

The invention recites a multi-zone temperature control system operable to control the temperature within a plurality of compartments. The system includes a scroll compressor operable at a speed to compress a flow of fluid and a condenser, operable to cool the flow of fluid. The system also includes a plurality of heat exchangers. Each heat exchanger is associated with one of the plurality of compartments and is operable to maintain the temperature of the compartment within a desired range. A plurality of valves are operable to direct and vary the amount of the flow of fluid from the compressor to the condenser and the plurality of heat exchangers. The valves are configurable to allow each of the heat exchangers to heat or cool their associated compartment. The system also includes a controller operable to control the valves to maintain the temperature of each compartment within its desired range.

Appl. No.:

12/721325

Inventors:

Gregory Robert Truckenbrod - Fridley MN, US

Richard W. Schmidt - Plymouth MN, US

International Classification:

B60H 1/32

US Classification:

62236, 62244

Abstract:

Systems and methods for providing power to a refrigeration unit or an air conditioner used on a hybrid vehicle. The system includes an accumulation choke, a PWM rectifier, and a frequency inverter. The accumulation choke is configured to receive a first AC power, a second AC power, and a DC power. The accumulation choke and PWM rectifier convert the received power into an intermediate DC power having a peak voltage. The PWM rectifier provides the intermediate DC power to the frequency inverter. The frequency inverter converts the intermediate DC power to an output AC power. The frequency inverter provides the output AC power to the refrigeration unit.
