▪ 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
considering the rise and fall of the pressure in the pipe. It is calculated using evap in temperature representing the pres-
sure of the indoor unit. In case that rise and fall of the pressure within the pipe are big, the pressure cannot be maintained
in accordance with load due to high evaporated pressure of the indoor unit despite the target pressure met. The level of
rise and fall of the pressure within the pipe is recognized considering the evaporated pressure using evap in. In case the
temperature reaches the setting temperature, maintain the target pressure judging from the evaporated pressure at a
certain point. In case that the evap in temperature is higher than the setting value, lower the target pressure. Reversely, in
case that the evap in temperature is lower than the setting value, raise the target pressure. In case that the setting value
of the evap in temperature is required to be adjusted, it can be adjusted in the main PBA by referring to the installation
manual.
