9 Terms and abbreviations
Term Explanation
Evaporator In the evaporator, energy from the heat source is absorbed by the
refrigerant passing through the evaporator. The refrigerant turns into
gas. (See the ”About your heat pump” section for further information).
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
multiplied by the time during which the difference is active. The
resulting value is referred to as the integral. The integral value is
automatically established when the heating system is in use. 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 refriger-
ant. (See the ”About your heat pump” section for further information).
Condenser In the condenser, the refrigerant supplies its heat energy to the
heat transfer fluid circuit. (See the ”About your heat pump” section
for further information).
CURVE The CURVE value is set via the display. The set value indicates the
supply temperature of the water that is transported to the radiators
at an outdoor temperature of 0°C.
Brine Is a water based mixture that transports energy from the heat
source to the heat pump. (See the ”About your heat pump” section
for further information).
Brine circuit The fluid circuit transports energy from the heat source to the heat
pump. (See the ”About your heat pump” section for further
information).
Refrigerant circuit Is the circuit in the heat pump that through evaporation, compres-
sion and condensation takes energy from the brine circuit and sup-
plies it to the heat transfer fluid circuit. (See the ”About your heat
pump” section for further information).
Refrigerant Is the fluid that transports heat from the brine circuit and supplies
it to the heat transfer fluid circuit. (See the ”About your heat pump”
section for further information).
Radiator Heater element, element.
Control computer The control computer controls the entire heating installation. All set-
tings are stored and the history of the installation is registered here.
The control computer’s settings can be changed via the display.
