| Abstract: | The performance of a transcritical CO_2 automotive air conditioning system was studied experimentally.The results show that lots of factors contribute to the practical performance of CO_2 system.These factors include the ambient temperature,the air flow rate through the gas cooler,the efficiency and speed of the compressor,and the operating high side pressure.The CO_2 outlet temperature of the gas cooler and the high side pressure level should be controlled in order to make the CO_2 system energy-efficient under variable operating conditions,which brings a high requirement to the controller. |
