In this chapter further studies on carbon dioxide-based systems are carried out. Heat transfer and fluid flow of a transcritical throttling process are investigated. A correlation that determines the optimum high pressure using the gas cooler outlet temperature, the effectiveness of internal heat exchanger and the suction line inlet quality is developed. The prediction uncertainty is within ±3.6 %.
