Natural Cooling - Viessmann Vitocal 300-G Manual

Natural cooling

NC-Box
Energy efficient and affordable cooling
with the NC-Box
The Viessmann NC-Box helps heat pumps
to provide cooling in a completely natural
way. In fact, it's really quite simple. On hot
summer days, the temperatures inside the
house are higher than those in the ground
or groundwater. The heat pump control unit
then switches to natural cooling, and uses the
ground or groundwater to dissipate the heat
from your living space.
Saving while cooling
The natural cooling function does not use all
the technology of the brine/water heat pump.
This means that, apart from the control unit
and circulation pumps, all other functions
remain off. Only a very small amount of
power is therefore consumed for operation.
This makes natural cooling a particularly
energy efficient and affordable method for
cooling buildings.
The effective thermal insulation of the NC-Box prevents the
formation of condensate.
Everything you need to keep cool
In the Viessmann "Natural Cooling Box", all
components are prefitted. This makes the
thermally insulated box not only compact, but
also particularly simple and quick to install.
With or without mixer
Depending on the sort of cooling needed, the
natural cooling box comes in two different
versions, either with or without mixer. The
integral mixer enables continuous operation
without falling below the dew point.
