A/C Compressor and Component Testbed The heart of each refrigerant cycle is the refrigerant compressor. qpunkt‘s A/C compressor testbed provides requirements. APPLICATION The main application of the compressor testbed is the performance- and endurance testing of refrigerant compressors. An advanced testbed automation provides fully automatic determination of performance characteristic maps and corresponding compressor efficiencies. External heating of the compressor allows for the replication and study of unfavourable thermal loads. All types of refrigerant compressors, electrically as well as mechanically driven, can be measured at the testbed. By extending the compressor testbed or integrating the compressor testbed into the A/C system testbed, all other components of a typical A/C system, such as evaporators, condensers, filters, etc. can be tested. Tests can be performed either standalone or fully integrated into a full A/C system setup. Due to the redundant setup of single components of the refrigerant cycle, each component can be replaced by the internal elements of the testbed at any time. / 72 SIMULATION SOLUTIONS TEST SYSTEM SOLUTIONS Electrification Battery Test Systems E-Motor Test Systems Power Electronics Test Systems Component Test Systems MBD on the virtual testbed Engine Test Systems End of Line Test Systems Real Life Test Systems Driveline Test Systems Fuel and Lube Test Systems Emission Test Systems and Certification Vehicle Test Systems Racing Test Systems TESTING EQUIPMENT SIMULATION TOOLS TESTING TOOLS CUSTOMER SERVICES efficient testing capabilities regarding functionality, quality and safety for all testing conditions and GENERAL TECHNICAL DATA (Adjustments can be made to suit a customer’s specific needs.)
