AIR CONDITIONING UNIT FOR OPERATION WITH A CURRENT-GENERATING SOLAR PLANT, SOLAR-OPERATED AIR CONDITIONING SYSTEM AND METHOD FOR THE SOLAR OPERATION OF AN AIR CONDITIONING UNIT

摘要

The invention relates to an air conditioning unit (2) for operation with a current-generating solar unit (4) which supplies the air conditioning unit (2) with energy. The air conditioning unit (2) is provided with an electric motor (10) for driving an air conditioning unit component (12), in particular a compressor, and with a regulator (14) for controlling the electric motor (10). In order to avoid the high costs of a battery for temporarily storing the energy generated by the photovoltaic unit, it is provided according to the invention that the regulator (14) has an intermediate circuit (16). The intermediate circuit (16) serves for temporarily storing the energy generated by the current-generating solar unit (4). If sufficient energy is present in the intermediate circuit (16), it is possible to provide the power peak required for starting the electric motor (10). In addition to the air conditioning unit (2), the invention also relates to a solar-operated air conditioning system (1) having such an air conditioning unit (2) and having a photovoltaic unit (4) which is connected to the intermediate circuit (16) of the air conditioning unit (2). The invention also relates to a method for the solar operation of the air conditioning units (2) using an electric motor (10) and a regulator (16) for the electric motor (10).
