Term Explanation
Evaporator In the evaporator, energy is retreived from the heat
source and the refrigerant passing through the evapora‐
tor turns to gas.
De-superheater In the de-superheater part of the total heating output is
released (approx. 15%). A higher temperature than the
normal condensation temperature can found here.
Integral INTEGRAL is the heating system’s energy balance. Heat
generation is controlled by a calculated requirement.
This value is determined by comparing the actual supply
temperature with its calculated supply temperature. The
difference between the temperatures is added over time.
The resulting value is referred to as the integral. The
integral is calculated automatically. The value of the
integral can be viewed in the display under the sub-menu
TEMPERATURE.
Compressor The compressor raises the temperature and pressure of
the refrigerant.
Condenser In the condenser, the refrigerant supplies its heat energy
to the heat transfer fluid circuit.
Curve The CURVE value is set via the display. The set value is
the calculated set point value of the flow line at outdoor
temperature of 0°C.
Brine Is a water based mixture that transports energy from the
heat source to the heat pump.
Brine circuit The fluid circuit transports energy from the heat source
to the heat pump.
Refrigerant circuit Is the circuit in the heat pump that through evaporation,
compression and condensation takes energy from the
brine circuit and supplies it to the heat transfer fluid cir‐
cuit.
Refrigerant Is the fluid that transports heat from the brine circuit and
supplies it to the heat transfer fluid circuit.
Radiator Heater element, element.
