The installation has a reversible heat recovery thermodynamic device (100) for recovery of heat from extracted air (15) from an interior space. A heat recovery device comprises a compressor (10), a pressure reducer (11), heat exchangers (9, 12) and a ventilator (13). The thermodynamic device preheats ambient air (8) in a heating mode, or pre-cools the ambient air in a cooling mode, and sends mixture of returned ventilation air (16) and the preheated or pre-cooled ambient air to a heat exchanger (4), a resistor (5) and/or a water/oil battery of a main heating and air-conditioning device (50). An independent claim is also included for a method for utilizing an embarked heating and air-conditioning installation. |
