ABSTRACT:
To capacity control a refrigeration system including a compressor, a condenser, and an evaporator all connected in a closed refrigeration circuit, the compressor having a plurality of adjustable inlet guide vanes and driven by an internal combustion engine, signals indicating the condenser pressure; the evaporator pressure; the inlet guide vanes position; the engine speed; the chilled water discharge temperature; and the engine intake manifold pressure are processed by a microprocessor to continuously calculate a surface speed and to equalize engine speed and calculated surface speed utilizing a fuzzy logic algorithm.
