Increasing pressure reference with heat recovery
The function will increase the gas pressure reference to the Pgc HR
Min. value when it receives a signal.
The function is activated by an on/off signal at the voltage input.
Increasing pressure reference with heat recovery, variable
reference
The function will increase the gas pressure reference to the value
where it receives a signal.
The function is activated by a voltage signal between 0-10 V.
• Between 0-2 V it is regulated normally
• At 2 V the reference changes to the setting “Pc HR Min”
• At 10 V the reference will increase further using the setting
“Pgc HR offset”
• Between 2-10 V the reference is variable.
Extra refrigeration capacity (“extra compressor”)
This function improves the system’s refrigeration capacity by
increasing the reference pressure (Pgc Ref) in the gas cooler. The
cooling performance increases to Q0+dh0.
The function also increases the load on the compressor motor as
pressure increases. Power consumption increases to Qm+dQm.
