How split systems work
3. How split systems work
An air/water heat pump extracts thermal energy from the
ambient air (low temperature) and transmits it together with
electrical drive energy in the form of useful heat (higher
temperature) to a heating and/or DHW circuit.
The heat pump consists of separate circuits linked together
via heat exchangers:
► Heat source circuit (extracting heat)
► Refrigerant circuit
► Heat sink circuit (supply of heat for room heating and/
or DHW)
Outdoor air is a heat source that is available everywhere
in unlimited amounts and can be utilised without a permit.
It is especially suitable for retrofit projects.
A split system consists of an indoor unit and a separately
installed outdoor unit. The outdoor air is routed through the
outdoor unit by means of a fan. The indoor and outdoor
units are connected through refrigerant lines.
Due to the defrosting function integrated into OCHSNER
air/water heat pumps, the system also operates flawlessly
at temperatures below -15°C.
For air/water heat pumps, the most efficient and therefore
most common operating mode is bivalent parallel opera-
tion.
Due to the integral defrosting function, monovalent oper-
ating mode is also theoretically possible. However, as the
heating output of an air/water heat pump at an outdoor
temperature of +15°C is approx. triple the heating output
at -15°C, such systems would be vastly oversized for opera-
tion in spring and autumn and therefore not recommended.
