Embodiment Construction

[0028] figure 1 There is shown a prior art maintenance station 1 for filling, emptying and / or flushing of an A / C system, in particular a mobile A / C system (hereinafter referred to as MAC) 2 . While utilizing existing maintenance stations (see figure 1 ) when performing normal maintenance on MAC2, externally flush reservoir 3, e.g. figure 1 As shown, it is installed between port G of MAC2 and port E of the maintenance station. Coolant is first drawn from MAC2 and then sucked into inner block 4. Coolant is drawn into the maintenance station 1 via port E, which is connected to port G of the MAC by a pipe or hose (not shown). Gaseous coolant is drawn into compressor 8 via service station line 5 and heated suction reservoir 6 discussed below, optionally through filter 7 . The gaseous coolant is compressed in the compressor 8 into heated gaseous coolant, or heated and partially condensed coolant, and passed through an oil separator 9 and used for condensation cooling before the ...

Abstract

A service station for the filling, emptying and especially flushing of air conditioning systems in vehicles or similar mobile air conditioning systems, which are operating on an inflammable coolant. The service station is coupled to the air conditioning system and comprises a cabinet in which a pipeline (5) for transporting the coolant connects a first port (E) with a compressor (8), cooling means and an internal cylinder (4) for storing the coolant as well as a second port (F). A heated flushing accumulator (14) is arranged inside the service station (1) between the first port (E) and the compressor (8). A method of flushing air conditioning systems is also disclosed, which is faster than known flushing methods. The system and the method eliminate the need for the externally mounted flushing kit, and provide a service station and a flushing method, which are safe to use when servicing and especially flushing air conditioning systems containing an inflammable coolant.

Description

technical field [0001] The invention relates to a system for performing maintenance and flushing of air conditioning systems, in particular mobile air conditioning systems of vehicles such as cars and trucks etc. [0002] In addition, the invention relates to a method of flushing such an air conditioning system. Background technique [0003] Today, air conditioning systems (A / C systems), such as those in vehicles, such as cars, buses or trucks, contain non-flammable coolants. During the manufacture of a vehicle, coolant is added and sometimes maintenance and repairs are performed on the A / C system in the vehicle. Equipment for performing this maintenance and repair are known. [0004] The most commonly used coolant is 1,1,1,2-tetrafluoroethylene, known as R134a. However, due to the high greenhouse effect (GWP, Global Warming Potential) of R134a, it is not allowed to use R134a as a coolant in new vehicles after January 1, 2011. [0005] Alternative coolants have been deve...
