Abstract: A power management system with DC/AC converter for providing power to electrical heating, ventilating and air-conditioning system, having a first electrical power interface (EPI) and a second EPI. Optional DC/DC converter having a third EPI and a fourth EPI, the third EPI being electrically coupled to the second EPI. A switching arrangement of the system has a common connection, the common connection being configured to be coupled to an electromagnetic machine, a first connection selectively electrically coupled to the common electrical connection, the first electrical connection further being electrically coupled to the second EPI and the third EPI, and a second electrical connection selectively electrically coupled to the common electrical connection, the second electrical connection further being electrically coupled to the fourth EPI. The first EPI, the second EPI, the third EPI, the fourth EPI and the common electrical connection are configurable as electrical power inputs and outputs.

Abstract: An adsorption separation unit and process. Valves are used to provide positive isolation between the various components of the unit, for example, when maintenance is required or when repairs are to be made. The valves comprises a first sealing element, a second sealing element and a bleed space between the sealing elements. A valve in a bleed line can be used to drain any fluid in the bleed space when the sealing elements are position in the sealing position.

Abstract: An auxiliary heating and cooling system for vehicles is provided wherein there are two alternative sources of primary thermal fluid, one being driven by the vehicle engine and the other by an electrical source separate from the vehicle, but both using the same secondary thermal fluid, operable under a lower pressure and being water based. Each of the primary fluids is alternatively connectable to a heat exchanger receiving the secondary fluid. The secondary fluid is connected to one or more fluid to air heat exchangers spaced as desired in the passenger compartment and to any internal container or constant temperature box heat exchangers, such as a refrigerator, as desired within the compartment. This invention permits use of modular components mounted from the exterior of the vehicle. Various fluid flow directional valves can be used as desired for flexibility in temperature orientation.
