Air conditioning unit

Abstract

The invention relates to an air conditioning unit ( 1 ), in particular for a stand-alone operation in a motor vehicle, comprising a compressor, condenser ( 3 ) and evaporator ( 2 ) that are situated in a coolant circuit, for cooling the air to be conditioned. According to the invention, the unit is equipped with a single fan ( 5 ) for the air that dissipates the heat and for the cooled air that is to be fed to the interior of the vehicle, said fan transporting part of the air through the condenser ( 3 ) and the other part through the evaporator ( 2 ).

1 .
