  "textContent": "Device for servicing an air conditioning system (27), in particular for air conditioning systems that use CO2 or R744 as refrigerant. The device has at least a first coupling (10) for connecting the device to a service connection of the air conditioning system, a storage container (3) for the refrigerant, a compressor (4), and a plurality of blocking valves (101-111) for the selective release of different fluid connections. A number of intermediate storage containers (7a, 7b, 7c) are provided, each with at least one storage valve (20a, 20b, 20c, 20a', 20b', 20c'). Through switching combinations of the blocking valves (101-111) and the storage valves (20a, 20b, 20c, 20a', 20b', 20c'), for each intermediate storage container (7a, 7b, 7c) an intermediate storage fluid connection (Aa, Ab, Ac) from the storage container (3) to the intermediate storage container (7a, 7b, 7c), a pressure increase fluid connection (Ca, Cb, Cd) from the storage container (3) via the compressor (4) to the intermediate storage container (7a, 7b, 7c), and a refilling fluid connection (Ba, Bb, Bc) from the intermediate storage container (7a, 7b, 7c) to the first coupling (10) can be selectively released.",
