Abstract:
The invention relates to an air conditioning unit with a coolant circuit which consists of a compressor, an evaporator, a collector located at the low pressure side between the evaporator and the compressor and an inner heat transfer unit with a beat transfer channel located at the high pressure side and a low pressure side beat transfer channel. According to the invention, the inner heat transfer unit has an at least segmentally spiraling and/or spiral-shaped steps between the outer and inner pipe of a coaxial pipe system. Additionally or alternatively, the inner heat transfer unit contains a multiple channel line which surrounds the collector in a spiral fashion and/or in which a low pressure side pipe longitudinal channel has a first segment which exits into said collector housing and a second segment which exits out of the said collector housing in addition to a high-pressure side pipe longitudinal channel which traverses the collector housing or leads into a first segment in a high-pressure execution chamber of said collector housing and a second segment leads out of the said chamber. Said invention can be used as a CO2-air conditioning unit in vehicles.
