Basic Control SiUS39-601
34 Function
2.2 Compressor PI Control
Compressor PI Control
Carries out the compressor capacity PI control to maintain Te at constant during cooling operation
and Tc at constant during heating operation to ensure stable unit performance.
[Cooling operation]
[Heating operation]
Controls compressor capacity to adjust Te to
achieve target value (TeS).
Te : Low pressure equivalent saturation temperature
(°F)
Te setting TeS : Target Te value
(Varies depending on Te setting, operating
frequency, etc.)
