Compressor – Capacity control
▪ Purpose
Adjust the compressor operation frequency through fuzzy control. This adjusts the capacity according to load in cooling
or heating mode.
▪ Concept
The compressor frequency is adjusted through fuzzy control to enable cooling according to the target low pressure.
The compressor frequency is adjusted through fuzzy control to enable heating according to the target high pressure.
▪ Control specifications in detail
In cooling case
The capacity of a compressor is controlled by assuming the target pressure during cooling operation.
Measure pressure using the pressure sensor (low pressure sensor) installed in the outdoor unit.
In case that the measured value is lower than the target pressure, lower the operating capacity of the compressor consid-
ering that the operating capacity is higher compared to load.
In case that the measured value is higher than the target pressure, raise the operating capacity of the compressor consid-
ering that the operating capacity is lower compared to load.
