US Patent:

20020040280, Apr 4, 2002

Filed:

Sep 26, 2001

Appl. No.:

09/963269

Inventors:

Stephen Morgan - West Chester PA, US

International Classification:

G01M007/00
G01M010/00

US Classification:

702/114000, 702/113000

Abstract:

A system and method for identifying refrigerant-based air conditioning system component-mode failures to provide field technician assistance in diagnosis and repair. A multiplicity of measurement probes for system pressure, system temperature, ambient temperature, ambient relative humidity and refrigerant identification are utilized with a microprocessor unit and a Weighted Probability Inference Engine (WPIE) process. Measured parameters are stored during specific modes of air conditioning system operation and are compared to a stored database of failure modes to determine potential system component-mode failures and provide troubleshooting guidelines. Specific failure modes are displayed to the user through a variety of interface devices.

Abstract:

A system and method for determining the presence of multiple vapor gases in a refrigerant sample. An infrared light source illuminates a refrigerant sample located in a test area between the light source and a plurality of infrared detectors. Each of the infrared detectors is sensitive to a different predetermined wavelength range of infrared light, with each of the detectors outputting a separate electrical signal corresponding to the infrared light received in its respective wavelength range. A processor then reads the output electrical signals and determines whether the electrical output signals correspond to a particular refrigerant and displays the result of the determination on a display.
