This paper deals with the development of optimum high pressure control algorithm for a transcritical CO₂ mobile air-conditioning system to achieve the maximum COP. The experiments were performed under idle and driving operating conditions. The experimental results demonstrated that the COP of the transcritical CO₂ system is a strong function of the gas cooling pressure. In other words, the COP was increased and then decreased with increase of the high pressure. Therefore the value of high pressure which has maximum COP could be selected. Furthermore, the strong(linear) relation between the optimum high pressure and the gas cooler outlet temperature was revealed, which suggests a simple controller of only one parameter for the transcritical CO₂ cycle.
