摘要： The invention relates to a multichannel flat tube for a heat exchanger comprising a plurality of parallel flow channels (2) which are adjacent to one another in a transversal direction with regard to the tube. According to the invention, the flow channels (2) have an oval cross-section, and/or the outer surfaces of the tube have a wave-shaped cross-contour which corresponds to the flow channels in such a way that the flat tube is thinner in the vertical direction of the tube between each two flow channels than in the area of a respective flow channel. The inventive flat tube can be designed for high working pressures while having a relatively low weight and a relatively high heat exchanging capacity. The inventive multichannel flat tube is used, for example, in CO2 motor vehicle air conditioning systems.

摘要： The invention relates to a regulating device for a coolant circuit of an air conditioning system. Said coolant circuit is divided into a high pressure side and a low pressure side by a compressor and an expansion element. The regulating device comprises a regulating part (8 to 12) located on the high pressure side and has a regulating part (1 to 7) located on the low pressure side for respectively regulating one or several system components which can be regulated and which are located on the high pressure side or on the low pressure side.

摘要： The invention relates to a collector pipe unit for a heat exchanger consisting of a block of several heat transmitting pipes. Said unit also has a collector pipe with a common slit into which the ends of heat transmitting pipes are inserted. According to the invention, the collector pipe is made up of one or several individual pipes that are fitted into each other or next to each other on the front face thereof with at least one respective, open longitudinal slit (2) on the front face of each individual pipe, whereby said slit is made before or after the collector pipe is assembled. This makes it possible to compensate manufacturing tolerances of the ends of the pipes that are inserted into the longitudinal slit with respect to the expansion thereof in the direction of said longitudinal slit. The invention can, for instance, be used in gas coolers and evaporators in CO2 air conditioning systems.

摘要： An air-conditioning system operated with CO2 for a vehicle has a high-pressure section that is connected to the output of a compressor and includes a gas cooler, a low-pressure section that is connected to the suction side of the compressor and includes an evaporator, and an expansion member connecting the high-pressure section and the low-pressure section. The expansion member has a fixed restrictor with a throttle opening of predetermined length and diameter connected between an inlet from the high-pressure section and an outlet to the low-pressure section whereby under all operating conditions of the system, a pressure of refrigerant in the high-pressure section of the system is limited to values of less than 14 MPa. The restrictor can be connected in parallel with a pressure limiting valve and can include two or more different throttle openings that can be selectively connected for refrigerant flow.

摘要： An optimized CO2 air-conditioning system for a vehicle has individual components designed and/or matched to one another in such a way that if the high pressures in the high-pressure section deviate by up to ±30% from the optimum high pressures, the associated optimum performance figures are reduced by no more than 20%. The individual components include a controllable compressor, a gas cooler, an internal heat exchanger, an evaporator and an accumulator. As a result, a fixed throttle expansion member can be used between the high-pressure and low-pressure sections of the system.
