The minimum required subcooling at the remote condenser level when
installed below is defined in the following table.
Example : If the remote condenser is 10m below the CCUN and the
condensing temperature is 50°C, the refrigerant subcooling leaving the remote
condenser shall not be below 4°C. To increase the amount of subcooling,
more refrigerant charge is required.
Table 11 - Maximum elevation (H) of CCUN above remote condenser
For recommended discharge line diameters refer to the following tables.
For vertical discharge line a double vertical riser must be used and designed
within state-of-the-art.
