Capacity control
3.4.1 Compressor PI Control
Compressor PI Control
Controls the compressor to maintain Te at constant during cooling operation and Te at constant
during heating operation to ensure stable compressor performance.
[Cooling operation]
Controls compressor capacity to adjust Te to achieve target value (TeS).
Te setting
Te: Low pressure equivalent saturation temperature (°C)
TeS: Target Te value
(Varies depending on Te setting, operating frequency, etc.)
[Heating operation]
Controls compressor capacity to adjust Tc to achieve target value (TcS)
Tc setting
Tc: High pressure equivalent saturation temperature (°C)
TcS: Target Tc value
(Varies depending on Tc setting, operating frequency, etc.)
