Heating and Cooling throughout the whole building, or individually if required. The occupant of an office, a room in a hotel, a laboratory or a shop etc... Is able to choose their desired temperature via the thermostat, to control the air conditioner completely independent of the rest of the building.
All the air conditioners are connected to a closed water loop. This water loop provides a stable and permanent heating or cooling source for the building. Such units that function in the cooling mode, reject the excess heat into the water loop. The others that operate in the heating mode will draw from the water loop the necessary heating. Therefore the system will compensate for the imbalance of heating/cooling requirements in the various areas : north face, south face, internal areas, IT rooms, conference rooms, entrance lobbies etc…... A heat injector and a heat rejection plant will be necessary for connection into the water loop to satisfy extreme external temperature conditions.
1- Personal Comfort
The User has the ability to start or stop his or her own unit. They can select,
via their thermostat the temperature of their convenience. In a correctly
designed system, each air conditioner can be set independent of the air quality
in the other areas. This concept provides multiple choices :
2- Low Capital Cost The system provides a very low cost installation
3- Low running Cost
The user will identify the following advantages : A favourable energy assessment,
A reduced maintenance cost due to the concept of a water loop with moderate
temperatures and closed to pollution. The absence of the constraints associated
with large central refrigeration systems. The simplicity of the small air
conditioning units which do not require regular maintenance other than the
changing of the air filter.
Localisation of risk : in the case of the failure of one unit, only that area
served is affected. During a long term contract, 10 years or more, suggested
by France ENERGIE, the return in stages TO THE FACTORY for a very modest forfeit
price and for a very short delivery.
