Backflow Line Dimensioning (Liquid) - Trane MERCURY EDAB 1105A Technical Manual

BACKFLOW LINE DIMENSIONING (LIQUID)

To avoid gas development inside the line and to ensure an
adequate pressure is reached inside the laminating unit,
the liquid line must be correctly dimensioned. Generally, the
systems are dimensioned so that pressure loss along the line
causes a variation of the saturation temperature between
0,5 K and 1 K
During the installation of the cooling unit, a solenoid
valve should be fitted on the liquid line between
the inner unit and the external condenser, to avoid
malfunctioning and to protect the compressor from
unwanted liquid migration during start- up.
