Title: Joseph L. Spurney: Innovator in Refrigeration Technology
Introduction
Joseph L. Spurney is a notable inventor based in Rochester, NY (US), recognized for his contributions to refrigeration technology. He holds a total of 4 patents, showcasing his innovative approach to enhancing air conditioning systems.
Latest Patents
One of his latest patents is the "Variable displacement refrigerant compressor passive destroker." This invention involves a unique design where the bellows in the stroke control valve of a variable stroke axial piston wobble plate refrigerant compressor are partially filled with an anti-freeze solution. This design continuously exposes the bellows to both suction pressure and crankcase pressure, effectively reducing the piston stroke at high compressor speeds while maintaining air conditioning performance.
Another significant patent is the "Control method for a variable displacement air conditioning system." This method tailors the operating point of a variable capacity automotive air conditioning compressor to the nonlinear control characteristics of variable displacement compressors. It employs a coarse gain closed-loop control when the error between desired and actual values is large, and fine control when the error is within a defined range. An adaptive tuning technique updates predetermined control point values to accommodate compressor differences and changing operating conditions.
