1 .7 Operating principle
The heat pump transmits the energy in the outdoor air to
the home to be heated and the production of domestic
hot water.
The heat pump is formed of four main elements inside
which a refrigerating fluid circulates (R410A).
- In the evaporator ( item 13 , figure 6, page 11 ):
The calories are taken from the outdoor air and
transmitted to the refrigerating fluid. As its boiling point
is low, it changes from the liquid state to the vapour
state, even when the weather is cold.
- In the compressor ( item 10 or 16 , figure 6, page 11 ):
The vaporised refrigerating fluid is pressurised and
thus carries more calories.
- In the condenser ( item 3 , figure 7 ):
The energy of the refrigerating fluid is transmitted to
the heating circuit. The refrigerating fluid returns to its
liquid state.
- In the pressure regulator ( item 9 or 15 , figure 6, page 11 ):
Then liquefied refrigerating fluid is reduced to low
pressure and its initial temperature and pressure.
The heat pump has a regulator that controls the
indoor temperature based on the measurement of
the outdoor temperature, regulation by water logic.
The ambient sensor (optional) provides a corrective
action to the water logic.
The hydraulic module is equipped gas generator which
operates at the request of the regulator:
- to provide additional heating during the colder
periods,
- to reach the DHW comfort value
- to provide a relay during "Peak rate" days
(load shedding or EJP function).
Priority is given to the operation of the heat pump.
When the heat pump is not sufficient for the heating, the
gas generator automatically takes over.
Leakproof type appliance (C13, C33).
The new air needed for combustion is taken from
outside the horizontal or vertical terminal and is then
aspirated into the boiler through the pipes (concentric
or separate).
Separate pipe adaptor (C53)
Configuration possible only in boiler room.
Chimney type appliance (B23, B23P)
The new air needed for combustion is taken from the
room where the appliance is installed.
