COMPONENTS
2.3.1.
REFRIGERANT CIRCUIT COMPONENTS
COMPRESSOR
A hermetic inverter rotary piston compressor that is highly efficient and uses an energy-saving DC electric
motor. Mounted on elastic vibration-damping compensators.
COMPRESSOR INVERTER MODULE
The inverter module infinitely controls the compressor speed using the sensor-controlled power
specification on the system controller. This means the compressor motor is continually monitored and
protected from damage.
CONDENSER
Featuring a plate structure (stainless steel, 1.4401). Featuring closed cellular insulation material on the
outside to minimise heat loss.
EVAPORATOR
Featuring a plate structure (stainless steel, 1.4401). Featuring closed cellular insulation material on the
outside to minimise heat loss and to prevent condensate formation.
REFRIGERANT COLLECTOR
A refrigerant collector ensures a bubble-free liquid upstream of the expansion valve in all performance
ranges.
FILTER DRYER
A hermetic-mechanical filter dryer with cartridges made of ceramic and hygroscopic material retains
impurities and any traces of moisture present in the cooling circuit.
THERMOSTATIC EXPANSION VALVE
The mechanical expansion valve with external pressure compensation regulates the gas flow to the
evaporator depending on the thermal load to ensure the intake gas overheats to a sufficient degree.
REFRIGERANT SIGHT GLASS WITH HUMIDITY INDICATOR
Used to check the refrigerant fill level and any possible humidity in the cooling circuit.
2.3.2.
WATER CIRCUIT COMPONENTS
SINK CIRCUIT (HOT
WATER)
SOURCE CIRCUIT
(AWN BRINE
CIRCUIT)
WATER FILTER
A steel filter net prevents the heat exchangers from clogging.
DIFFERENTIAL PRESSURE CONTROLLER
A differential pressure sensor allows continuous
water circulation to be controlled in the AWN heat
exchanger circuit. In the event of a fault, the
cooling circuit is switched off.
SAFETY VALVE (6 BAR)
In the event of pressure faults in the brine and heating water pipes, a safety valve is triggered and
excess pressure is released. This can be connected to a drain on site.
