Abstract:
An HVAC system to be installed in a vehicle comprises a battery management controller. The battery management controller comprises at least one connection for electrically coupling a first power source with a first voltage; at least one connection for electrically coupling a second power source with a second voltage; and a first memory storage device configured to record data collected by the battery management controller. The battery management controller is configured to run a temperature control system and to supply power to the temperature control system from a combination of the first and second power sources with a combined voltage, and wherein the second power source is disconnected when the combined voltage drops below a predetermined amount.
Abstract:
An HVAC system that uses a mechanical compressor powered by vaporized refrigerant and/or electric power, to increase efficiency in a jet ejector cooling cycle. The device is further able to convert thermal energy to electric power which may be used to meet internal or external requirements, for example, to activate control a system or charge a battery. Compatible input power includes only thermal energy, only electric energy or a combination of the two. Motive thermal energy may be input at a wide range of temperature and include both waste and non-waste heat sources such as that from an internal combustion engine and fuel-fired heater. Solar thermal and solar photovoltaic may also be used when collected from either concentrated or non-concentrated sources. Embodiments of the device are equally well suited to both mobile and stationary applications.

Abstract:
A cascade cooling system that uses low-grade thermal and other energy input sources to provide refrigeration and air conditioning in stationary and mobile applications. A two-loop embodiment includes a heat-powered first loop incorporating a vapor-jet compressor and a second loop based on a mechanical compressor powered by an electric motor or other source of rotational torque. The system uses waste heat, solar thermal or a fuel-fired heat source to partially or fully offset mechanical/electrical energy input. The system can also operate entirely on thermal, electrical or mechanical input. The ability to use multiple energy sources in any combination maximizes energy efficiency, performance and reliability. The system is well suited to making beneficial use of waste heat in vehicle applications. In stationary applications, solar thermal and/or waste heat from industrial processes can be used to improve the efficiency of conventional cooling systems.

Abstract:
An environmental control and power system (ECAPS) including an ECU with at least one variable-speed compressor driven by a DC motor, wherein the ECU is adapted to condition air and output the conditioned air and a variable-speed diesel engine connected to a generator. The generator is configured to vary in speed so as to output AC power at a variable frequency. The system includes a rectification assembly which transforms the AC power from the generator and/or external AC power into DC power. The ECAPS directs the DC power to the DC motor to drive the variable-speed compressor and varies, in a controlled manner, at least one parameter of the outputted conditioned air from the HVAC system.

Abstract:
A variable speed air compressing system includes a compressor, a motor configured to actuate the compressor, and a rectifier configured to receive alternating current from a first power source and to provide rectified direct current having a first voltage. The system also includes an inverter configured to receive the rectified direct current and to receive direct current from a second power source having a second voltage. The inverter is configured to provide alternating current to the motor. The alternating current provided to the motor is based on the rectified direct current if the first voltage is greater than the second voltage and the alternating current is based on the direct current from the second power source if the second voltage is greater than the first voltage.
