Pressure expansion vessel
The brine circuit should be fitted with a pressure expansion
vessel. If there is a level vessel, this should be replaced. The
brine side should be pressu rised to at least 0.5 bar.
The pressure expansion vessel should be dimensioned as
set out in the diagram, to prevent operating disturbances.
The pressure expansion vessel covers the temperature
range from -10 °C to +20 °C at a pre-pressure of 0.5 bar
and the safety valve’s opening pressure 3 bar.
Available pressure, heating medium side
Available pressure, collector side (ethanol 28 %)
Limiting condenser out and condenser in
For HTF in hotter than -5 °C, limiting of max condenser
out 65 °C and max condenser in 58 °C.
For HTF in colder than -5 °C, max condenser out and max
condenser in lowers automatically, according to diagram,
additional heat maintains desired supply temperature.
For HTF in lower than -8 °C, the compressor stops and the
desired supply temperature is only maintained by addi-
tional heat.
