In cooling case
The capacity of a compressor is controlled by assuming the target pressure during cooling operation.
-
ing 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 consider-

▪ The target pressure value is as in the table and the initial setting value is 8.0 kgf/cm2,g. The target pressure is adjusted con-
sidering the rise and fall of the pressure in the pipe. It is calculated using evap in temperature representing the pressure of
