摘要： The invention relates to a method of refrigerant level monitoring in a refrigerant circuit of an air-conditioning or heat-pump system having a compressor and a refrigerant which may, depending on the operating point, be operated in the supercritical range. The method includes standstill level monitoring with the compressor switched off and/or in-operation level monitoring with the compressor switched on. In the case of in-operation level monitoring, the refrigerant overheat (dTü) at the evaporator is registered and, in the event of excessive overheat, it is concluded that there is underfilling. At a standstill, the pressure and temperature of the refrigerant are registered, and it is concluded that there is an improper refrigerant filling level if the pressure (pKM) lies below a minimum pressure value (pmin) or the temperature (TKM) lies above a maximum saturation temperature value (TS) with the pressure being outside a predefinable intended pressure range ([pu,po]).

摘要： The invention relates to a heat carrier comprising at least one collector pipe (1) for receiving the ends of flat pipes (10a), especially for a CO2 air conditioning unit for motor vehicles. The collector pipe (1) is formed by an open hollow profiled section (7) with edges (8, 9) forming a continuous longitudinal slit extending in a longitudinal direction and the ends of the flat pipes (10a), which are twisted at an angle of 90°, are received in a fluidically tight manner in the longitudinal slot. According to the invention, the edges (8,9) partially abut, forming a separating joint (4) and are partially rolled back, forming receiving openings for the ends of the flat pipes (10a). The receiving openings are produced by plastic deformation.

摘要： The invention is essentially characterized in that in a first step a substrate is provided, which is coated with defined pattern of protrusions of a coating layer of a different material, so that an interface is defined between the substrate and the coating layer. As an example, the patterned coating layer can be applied by first forming an essentially homogeneous coating layer, which is then partially removed by means of photolithographic and etching techniques, leaving nanometer sized protrusions in that layer. As a next step, the surface provided with these structures is modified by selectively removing protrusions by means of a micro-device. Such a micro-device can be formed in a similar way to a scanning probe microscope (SPM) tip. The presence or absence of a protrusion represents a readable data bit information.
摘要翻译：本发明的基本特征在于，在第一步骤中，提供了衬底，其涂覆有不同材料的涂层的突出物的限定图案，使得在衬底和涂层之间界定界面。作为示例，可以通过首先形成基本均匀的涂层来施加图案化涂层，然后通过光刻和蚀刻技术将其部分地去除，在该层中留下纳米尺寸的突起。作为下一步骤，具有这些结构的表面通过借助于微型装置选择性地去除突起而被修改。这样的微器件可以以与扫描探针显微镜（SPM）尖端类似的方式形成。突起的存在或不存在表示可读数据位信息。

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.
