Is it ok to have one liquid line for both freezer cabinets and chiller cabinets? The system has a compressor rack with 2 bitzer compound compressor for the freezers, 3 single stage compressor for the chillers and 1 condenser. Suction line is one for the freezer and one for the chiller line. Is this a good design? Also what is the formula for the calculation of liquid receiver? Refrigerant is R404a or R22. Thank you in advance for the help.
