Water cooled
The water cooled models are suitable for all those installations where it is not possible to position the air cooled external unit.
Functioning and installationThe wide range includes wall mounted, floor/ceiling, cassette and ducted models.
Condensing unit for the water cooled models.
FUNCTIONING
The air conditioner works following the refrigerating cycle combined with the compression cycle.
This is the process both to cool and heat:
The air is cooled by the gas present in the copper pipes.This gas is compressed and transformed from the liquid to gasiform state, reducing the heat during this transformation. The evaporating liquid, in this way, produces the refrigerating effect. The gas cools the air that shall be introduced in the ambient at a lower temperature.
On the contrary, when the gas returns from the gasiform to the liquid state, the heat shall be produced. This heat shall be transferred from the gas to the air that shall be introduced in the ambient at a higher temperature (heat pump).
In the water cooled the difference is that the refrigerating gas inside the pipework is cooled by water instead of air, allowing an excellent performance.

INSTALLATION
These models are suitable for installation in ambients of small dimension or in cases of lack of a perimetral wall as for example in a bathroom or utility room.
The indoor and the condensing unit are connected by:
- electrical connection;
- copper pipes connections for the refrigerant R410a.
For this type of installation is necessary the connection to the main water supply. Artel provides as equipment the “kit for the connection to the water supply system” composed by the tap, the connection and the filter.
