Abstract (en)
An air conditioning system (1) is described that is structured to be installed in a building (2) which comprises at least one internal compartment (3) and a hydraulic system (4) comprising at least two ducts which extend into the building between said internal compartment and an external location to said building (2). The air conditioning system comprises a heat pump unit which is arranged in the external location, is hydraulically connected to the two ducts, and is configured to carry out a heat exchange between the water circulating in the ducts and the ambient air in the external location. The system further comprises a heat-pump fan coil unit which is arranged in the compartment, is hydraulically connected to the two ducts, and is configured to carry out a heat exchange between the water circulating in the ducts and the ambient air in the internal compartment. The system further comprises a control system which controls the heat pump unit in order to maintain the temperature of the water circulating in the ducts in a predetermined temperature range.
