Definitions
- the invention relates to a device for filling vehicle air conditioning systems with refrigerant R744, wherein the device has at least one storage tank for liquid refrigerant which is operatively connected via at least one pumping station and a supply line and a return line to a filling system, from which the refrigerant via an adapter in the vehicle air conditioning system is fed.
- 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 vehicle air conditioning systems are first filled with the manufacturer in the vehicle final assembly using filling systems.
- the accuracy requirements with regard to the masses to be filled are therefore to be placed on the filling system.
- the task of the manufacturers of filling systems is to control the phase conditions which change as a result of temperature and pressure, and thus also the density of the refrigerant, in order to be able to fill in the required tolerance limits.
- this is especially difficult with the R744 refrigerant because significant changes are already made in the assembly hall temperature range and in compression by required pumps.
- the object of the invention is to provide a technical solution with the refrigerant R744 can be kept constantly in the liquid phase within a supply concept with a filling system.
- the object is achieved in that a temperature sensor and a valve circuit are arranged at the transition region between the supply line and filling system, which regulate the refrigerant flow in such a way depending on the particular actual operating situation, that in an interruption of the decrease of refrigerant which inevitably warming by the Abtenepause refrigerant for Storage tank returned or removed and cold refrigerant is conveyed from the storage tank to the filling.
- the control of the valve circuit and consequently a return and / or cooling of the refrigerant is initiated by the filling system.
- the device triggers a return and / or cooling of the refrigerant only at times in which the application-specific operating behavior of the filling system is not affected.
- an adapter tray is designed so that the adapter can be stretched in its storage position via a sealing fit on a special port (service port) such that via a the adapter storage associated return line is carried out a return and / or cooling of the refrigerant.
- the refrigerant R744 is kept in its liquid phase with a valve circuit and temperature monitoring assigned to the filling system.
- This makes it possible to fill the vehicle air-conditioning system within narrow tolerance limits that can be achieved with Massflow measuring devices without additional real-time correction of line sections until they enter the air conditioning system.
- an automatic process is realized, which takes into account the removal profile through the filling system on the assembly line and, for example, automatically establishes the operational readiness of the system at the supply concept at the beginning of the shift.
- the filling distance up to the adapter is also considered.
- the adapter can be brought into operative connection with a service port, which is similar to the vehicle valve by a sealing positive engagement within the adapter tray.
- the adapter is clamped in its tray accordingly, a release of heated refrigerant and a Nachellen of cold refrigerant are automatically possible. Accordingly, can be dispensed with advantageously in a return line in the adapter and in the hose package.
- the device shown in the drawing is designed for a first filling of vehicle air conditioning systems with the refrigerant R744.
- the device has a storage tank 1 for liquid refrigerant R744, which is in operative connection via a line 5 and a pumping station 2 and via a supply line 6 and a return line 7 with a filling system 3.
- the refrigerant R744 is fed via an adapter 4 in an assembly of the vehicle air conditioning system.
- Tanks 1 for liquid refrigerant R744 with a connected pumping station 2 as well as the ring lines and return lines required for this purpose are known as prior art, so that these assemblies need not be explained in detail at this point.
- the refrigerant R744 it is essential to regulate the temperature and pressure of the refrigerant R744 automatically, to take the extraction profile into account and to leave the enthalpy diagram corresponding to the medium in a largely optimal range.
- a range of 5 ° C to 18 ° C and a pressure of 60bar is mentioned here. If the refrigerant R744 can be filled within these physical limits up to the filling opening in the vehicle air conditioning system, a filling without a complex real-time correction using Massflow measurement technology is possible.
- the supply system for the refrigerant R744 also comprises a return line 7 in addition to the supply line 6.
- a temperature sensor T and a valve circuit 10 are arranged
- the valve circuit 10 is assigned to the filling system 3 advantageous because of this, the removal regime is known or controlled by itself.
- a return or cooling of medium can be carried out in times in which the required performance is not impaired.
- the filling line within the filling system 3 up to the adapter outlet must also be monitored with regard to the medium temperature and pressure position.
- the adapter tray can be advantageously designed so that the adapter 4 is stretched in the storage position on a special connection similar to that of the vehicle system.
- medium can be drained and colder medium via the supply line and the filling 3 nachgeschreibt.
- the controller is advantageous to leave the filling system 3, since it is the removal regime known or controlled by them.
- a media return or cooling can be performed at such times in which the required performance is not affected.
- the removal or return of the medium may e.g. via a line 8 via the roof of the building or a return line 9 to the supply tank 1 done.
