摘要:
An air-treatment system includes a cooling circuit, a first heat exchanger in thermal communication with the cooling circuit, and a secondary circuit in thermal communication with the first heat exchanger. The air-treatment system also includes a controller in communication with at least one of the cooling circuit, the first heat exchanger, and the secondary circuit. The controller is operable to receive at least one input indicative of a desired ambient condition, operable to receive at least one input indicative of current ambient conditions, operable to receive at least one input indicative of at least one of the cooling circuit operation and secondary circuit operation, and operable to change the operation of at least one of the cooling circuit and the secondary circuit when the current ambient condition is outside of a desired operation condition range.

A thermal management system for a vehicle includes an engine operable to generate energy. An energy storage unit may be associated with the engine and adapted to receive and store the energy generated by the engine. A temperature control unit may be associated with the energy storage unit and adapted to control a temperature in the vehicle. The temperature control unit may be adapted to selectively draw stored energy from the energy storage unit to control the temperature when the engine is not operating. A controller may be adapted to monitor an operating condition of the thermal management system and to control the transfer of the energy from the engine to the energy storage unit based on the monitored operating condition.

A mounting system is provided for supporting a weight of a compressor in a mobile application. The compressor may include a top end and a bottom end. The mounting system may include a housing having a top plate and a bottom plate, the top plate being disposed a distance above the bottom plate. A mounting bracket may be connected to the top plate and the bottom plate. An isolation assembly may be disposed on the mounting bracket and may be configured to connect to the compressor at a connecting location below the top end and above a location at or adjacent to the bottom end of the compressor. The isolation assembly is configured to support the weight of the compressor at the connecting location without the compressor being supported adjacent to its bottom end.

摘要:
A valve is provided having a housing with an inlet and an outlet. Within the confines of the housing is a fluid flow path that allows for fluid communication between the inlet and the outlet. The valve includes a valve element that is movable to and from a position where it blocks fluid communication along the fluid flow path, thereby closing the valve. The valve also includes a resilient member provided in a chamber of the valve that is fluidly sealed from the fluid flow path. The resilient member urges the valve element to move to the position for closing the valve. When the pressure of fluid entering the inlet exceeds a preselected amount, the pressure of the fluid overcomes the urging of the resilient member and the valve element moves towards a position that allows fluid communication along the fluid flow path, thereby opening the valve.
