Definitions
- the invention relates to a device for filling vehicle air conditioning systems with refrigerant R744, wherein the device comprises a filling system with pumps, lines and storage, an adapter hose line as Be Heilllumble, an adapter with a filling valve and a mass measuring system at the beginning of the Be Stirllumble, wherein at the beginning and at the end the filling path are each a temperature and pressure sensor for determining the density of the refrigerant are arranged and wherein the device is associated with a control system.
- the manufacturers of air conditioning systems determine which mass is to be filled into the respective air conditioning system. In this case, compliance with the required close tolerances of great importance in order not to affect the cooling performance and to avoid damage to the air conditioning system by a different filling compound.
- the properties of refrigerants are described in enthalpy diagrams, which show correlations of pressure, temperature, density and phase states.
- the refrigerant R744 undergoes different states of aggregation due to its properties in the typical temperature range that prevails over the year in European factories. Depending on the temperature, pressure and density are.
- Fig. 1 shows the structure of a typical filling line for refrigerant R744.
- a known as prior art filling section consists essentially of a hydraulic cabinet (1) with pumps, lines and memory, a mass measuring system (2), an adapter hose line (3) and an adapter (4) with a filling valve (8).
- a disadvantage of this embodiment is that in the adapter hose design a possible technical segmentation of the hose is not considered and that measuring points and calculation do not form a functional unit that meets the requirements of different hose segments. Because often adapter hose lines are guided by handling systems, an automatic Schlaucheinzug and hose storage over different temperature zones or have coupling points with cross-sectional changes and other specific embodiments.
- Object of the present invention is to provide a technical solution for filling vehicle air conditioning systems, which allows a calculation of mass deviations in line sections when filling with refrigerant R744.
- the adapter hose line is segmented by introducing a plurality of respectively separate temperature and pressure sensor pairs, which are included centrally in a correction calculation by a mass calculator.
- the mass calculator continue to have the parameters of a mass measurement by the mass measuring system available, so that the control of the filling valve of the adapter is taken over by the mass calculator.
- the Massekalkulator can be performed with any number of temperature and pressure sensor pairs as well as with mass measuring system and Golfventil facedung as an encapsulated unit and thus independent of the performance of a plant control system solve the metrological / calculatory task reproducible.
- Fig. 1 shows the basic structure of a filling line for refrigerant R744 (Stand of
- FIG 2 shows a modified filling section for refrigerant R744, in which a temperature and pressure sensor is introduced at the beginning and at the end of the filling line (prior art)
- Fig. 3 shows the basic structure of a device according to the invention for filling with refrigerant R744
- Fig. 1 and Fig. 2 show filling lines according to the already described prior art, as essential components a hydraulic cabinet 1 with pumps, lines and memory, a mass measuring system 2, an adapter hose 3, an adapter 4 with filling valve 8, temperature and pressure sensors 5a and 5b and a control system 7 have.
- Fig. 3 shows an inventively designed filling line for refrigerant R744.
- a hydraulic cabinet 1 with pumps, lines, memory, a mass measuring system 2, an adapter hose 3 and an adapter 4 are provided with a filling valve 8 in a known manner.
- a temperature and pressure sensor 5a and 5b are also arranged in each case and the device is also assigned a control system 7.
- the adapter hose 3 is designed segmented and can be split. This segmentation is derived according to functional requirements, preferably under aspects of handling.
- the individual segments of the adapter hose 3 are each separate temperature and Pressure sensor pairs 6 assigned. Through these temperature and pressure sensor pairs 6, which can be expanded or reduced in number, a calculation of density deviations in each line segment of the adapter hose 3 is possible.
- All measured data are recorded by a mass calculator 9 and processed in real time.
- the control of the filling valve 8, which is dependent on the correction calculation due to different density deviations and the mass measurement at the entrance of the route is taken over by the mass calculator 9.
- An interface to the control system 7 allows the transfer of process parameters such as the mass to be filled and a transfer of the results achieved.
