Appl. No.:

10/134875

Inventors:

Terry Zeigler - Byron IL, US
Eric Elias - Loves Park IL, US

Assignee:

Bergstrom, Inc. - Rockford IL

International Classification:

F25B029/00

US Classification:

165240, 165202, 165271, 62133, 236 493, 236 78 R

Abstract:

An air conditioning system for use in an over-the-road or off road vehicle is provided that allows operation during both engine on and engine off conditions. The system utilizes a variable speed, motor driven compressor controlled by an intelligent power generation management controller. This controller selects from one of the available sources of power on the vehicle to drive the compressor, and modulates the compressor speed and capacity based on operational parameters and source availability and depletion. The controller may also operate a coolant or air heater to provide heating to the interior compartments.

Abstract:

An air conditioning system for use in an over-the-road or off road vehicle 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.

Abstract:

An air conditioning system for use in an over-the-road or off road vehicle is provided that provides a method of operation during both engine on and engine off conditions. The method operates the air conditioning system at one capacity when the engine is running, and at a second capacity when the engine is not running. The selection of these capacities is based on the power capacity of the source of electric power from which the air conditioning system is operated. When a storage battery is used to power the air conditioning system during engine off conditions, the second capacity is lower than the capacity at which the system is operated when the engine is running.

International Classification:

F25B 29/00

US Classification:

165240000, 062238600, 062236000

Abstract:

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.
