▪ In heating case
The capacity of the compressor is controlled by assuming the target pressure during a heating operation process.
Measure the pressure using the pressure sensor (high pressure sensor) installed in the outdoor unit. In case the
measured value is lower than the target pressure, enhance the operating capacity of the compressor according
to fuzzy control considering that the operating capacity is lower compared to load. In case the measured value is
higher than the target pressure, lower the operating capacity of the compressor according to fuzzy control consid-
ering that the operating capacity is higher compared to load.
The target pressure value is as in the table and the initial setting value is 30.0 kgf/cm2,g. In case that the setting
value of the target pressure shall be adjusted, it can be adjusted in the main PBA by referring to the installation
manual.
