Installation / AdjustmentPipe connectionsPressure expansion vesselThe brine circuit should be fitted with a pressure expansionvessel. If there is a level vessel, this should be replaced. Thebrine side should be pressu rised to at least 0.5 bar.The pressure expansion vessel should be dimensioned asset out in the diagram, to prevent operating disturbances.The pressure expansion vessel covers the temperaturerange from -10 °C to +20 °C at a pre-pressure of 0.5 barand the safety valve’s opening pressure 3 bar.Limiting condenser out and condenser inFor HTF in hotter than -5 °C, limiting of max condenserout 65 °C and max condenser in 58 °C.For HTF in colder than -5 °C, max condenser out and maxcondenser in lowers automatically, according to diagram,additional heat maintains desired supply temperature.For HTF in lower than -8 °C, the compressor stops and thedesired supply temperature is only maintained by additionalheat.Pressure expansionkexpansionskärlvessell60504030201000Brinevolume Köldbärarvolym100 200 300 400 500 600 700 800 900 1000 1100 1200 1300 1400 1500 lCondenser outKondensor ut°C706866164626058256545250-9 -7 -5 -3 -1 1 3 5 7 9 11 13 15 17 19 211.
