1.2.2 Compressor PI Control
Carries out compressor capacity control to maintain Te at constant during cooling operation
thus ensuring stable unit performance.
Cooling operation
Controls compressor capacity to achieve target Te value (TeS).
Te: Low pressure equivalent saturation temperature (°C)
TeS: Target temperature of Te (Varies depending on Te setting, operating frequency,
etc.)
Compressor Frequency
4/5 HP
Depending on the operating conditions of the compressor, the compressor can be run in an
operating mode different from the modes listed in the table above.
