A refrigeration type air conditioning assembly employing a heat transfer medium for use in a motor home vehicle or the like having a front passenger area and a rear living area, and which is equipped with an engine, a Source of d-c voltage, and an electrical outlet for connecting the motor vehicle or the like to a source of a-c line voltage, comprising: a first compressor means, having a suction port and a discharge port, for compressing the gaseous heat transfer medium passing therethrough; means for drivingly connecting said first compressor to the engine of the vehicle; a second compressor means having a suction port and a discharge port, for compressing the gaseous heat transfer medium passing therethrough; an electric drive motor drivingly connected to said second compressor and mounted on the vehicle; electrical conductor means connected to said electric drive motor for electrically connecting said electric drive motor to the electrical outlet of the motor vehicle to provide a-c line voltage to said electric drive motor; a first condenser coil means, having an inlet port and an outlet port and mounted on the motor vehicle, for condensing the gaseous heat transfer medium passing therethrough into the liquid state; a second condenser coil means, having an inlet port and an outlet port and mounted on the motor vehicle, for condensing the gaseous heat transfer medium passing therethrough into the liquid state; a first evaporator coil means, having an inlet port and an outlet port and mounted on the motor vehicle proximate to the front passenger area, for evaporating the liquid heat transfer medium passing therethrough into the gaseous state; a second evaporator coil means, having an inlet port and an outlet port and mounted on the motor vehicle proximate to the rear living area, for evaporating the liquid heat transfer medium passing therethrough into the gaseous state; a third evaporator coil means, having an inlet port and an outlet port and mounted on the motor vehicle proximate to the rear living area, for evaporating the liquid heat transfer medium passing therethrough into the gaseous state; first discharge conduit means interconnecting the discharge port of said first compressor means and the inlet ports of said first and second condenser coil means, for conducting gaseous heat transfer medium from said first compressor means to said first and second condenser coil means; second discharge conduit means interconnecting the discharge port of said second compressor means and the inlet ports of said first and second condenser coil means for conducting gaseous heat transfer medium from said second compressor means to said first and second condenser coil means; first liquid conduit means interconnecting the outlet port of said first condenser coil means and the inlet port of said first evaporator coil means for conducting liquid heat transfer medium from said first condenser coil means to said first evaporator coil means; second liquid conduit means interconnecting the outlet port of said second condenser coil means and the inlet port of said second evaporator coil means for conducting liquid heat transfer medium from said second condenser coil means to said second evaporator coil means; third liquid conduit means interconnecting the outlet port of said first condenser coil means and the inlet port of said third evaporator coil means for conducting liquid heat transfer medium from said first condenser coil means to said third evaporator coil means; first suction conduit means interconnecting the outlet port of said first evaporator coil means and the suction port of said first compressor means for conducting gaseous heat transfer medium from said first evaporator coil means to said first compressor means; second suction conduit means interconnecting the outlet port of said second evaporator coil means and the suction port of said second compressor means for conducting gaseous heat transfer medium from said second evaporator coil means to said second compressor means; third suction conduit means interconnecting the outlet port of said third evaporator coil means and the suction port of said first cOmpressor means for conducting gaseous heat transfer medium from said third evaporator coil means to said first compressor means; fourth suction conduit means interconnecting the first, second, and third suction conduit means; first blower means disposed adjacent to said first evaporator coil means for moving air over said first evaporator coil means and into the front passenger area; second blower means disposed adjacent to said second evaporator coil means for moving air over said second evaporator coil means and into the rear living area; third blower means disposed adjacent to said third evaporator coil means for moving air over said third evaporator coil means and into the rear living area; air circulating means mounted on the vehicle for moving air over said first and second condenser coil means; a first expansion valve means connected to said first liquid conduit means and disposed adjacent to the inlet port of said first evaporator coil means; a second expansion valve means connected to said second liquid conduit means and disposed adjacent to the inlet port of said second evaporator coil means; and a third expansion valve means connected to said third liquid conduit means and disposed adjacent to the inlet port of said third evaporator coil means.
