Its purpose is to provide new insights into complete A/C systems. The modular design of the test bed allows for custom setups to fit the individual needs of each customer, and supports the efficient development of refrigerant cycles and entire A/C system of motorcars, commercial vehicles as well as motor trucks. APPLICATION The A/C test bed has a wide range of applications. Applications range from the development of new A/C systems using R134a, 1234yf, R744 (CO2) and alternative refrigerants, to performance evaluation studies of air conditioning units in connection with the refrigerant cycle, and even to the analysis of potential flaws and faults in the system. The test bed facilitates the development of one or two stage evaporator systems to increase overall system efficiency, tune expansion valve performance to cycle behaviour, and analyse oil displacement and oil transportation, etc. Refrigerant-air heat exchangers are supplied with conditioned air (temperature, volume flow, humidity), thus allowing for the simulation of stationary loads as well as full driving cycles. Using this methodology it is also possible to develop entire refrigerant cycles of hybrid vehicles with integrated battery cooling. Using the test bed as a closed climatic chamber, the refrigerant cycle can be exposed to a wide range of loads and operating conditions. If required, it is possible to generate a controlled outdoor climate with a temperature range between -25°C and 60°C including control of the humidity in the test environment. It is also possible to simulate any desired weather condition as well as e.g. a rapid transition (quick cool-downs & quick heat-ups). Another area of application for the A/C test bed is the use as a climatic chamber for measuring different test set-ups and vehicles.
