Abstract

An air conditioning system for use in an over-the-road or off road vehicle that provides operation during both engine on and engine off conditions. The system includes a variable speed compressor, a motor, and a controller. The controller receives electric power from the vehicle's electric power generation system when the engine is on to enable operation of the compressor during an engine on condition. When the engine is off, the controller receives electric power from a battery to enable operation of the compressor during the engine off condition.
