4.2 Operating principle
The heat pumps in the iMPI V200 range extract the heat found in the air to
restore it to the heating and/or domestic hot water circuit via the refrigerant
fluid. The efficiency of a heat pump is expressed in the form of a
coefficient of performance (COP), defined as the ratio between the heat
provided and the power consumed.
The heat pump comprises an evaporator, a compressor, a condenser and
an expansion valve. The indoor module includes the condenser. The other
components (evaporator, compressor and expansion valve) are located in
the outdoor unit.
1. The refrigerant fluid in the circuit is converted from the liquid state to
the gaseous state in the evaporator, making it possible to recover heat
from the air.
2. The compressor increases the fluid pressure, which thus increases
the temperature.
3. In the condenser, the fluid transfers the heat to the heating circuit
while converting to the liquid state.
4. The refrigerant passes through the thermostatic expansion valve and
returns to the initial state at low pressure and low temperature before
returning to the evaporator.
