A heating, ventilating and air conditioning (HVAC) system for use in an over-the-road or off road vehicle is provided. The HVAC system may be operated regardless of the operational state of the engine. That is, the HVAC system may be operated to condition the interior compartments of an over-the-road vehicle while the engine is running and while the engine is in a no-idle (off) condition. In general, the HVAC system efficiently shares one or more typical air conditionings components with those already found in the vehicle. In one instance, the HVAC system operates an electrically-driven compressor when a belt-driven compressor is idle. In another case, the HVAC system operates both an electrically-driven compressor and a no-idle condenser when a belt-driven compressor and condenser are idle. In yet another embodiment, the HVAC system shares an evaporator.

Vehicle air conditioning and heating system providing engine on and off operation

An air conditioning system for cooling an environment in an over-the-road vehicle is provided. The air conditioning system includes an electrically driven, variable speed compressor, which enables operation of the system when the engine of the over-the-road vehicle is not running. The system is modular and is adapted to be installed in the side luggage compartment of the vehicle to enable existing vehicles to be retrofitted to provide no-idle air conditioning. The housing of the system defines two flow paths therethrough; one cold air path and one hot air path. The hot air path is configured to intersect the condenser at least two times, and draws and expels the air through the same wall of the housing. An air direction device is used to reduce the amount of air recirculation through the hot air path to increase the efficiency of the system.
