Optimisation of a carbon dioxide transcritical cycle with flash-gas removal.
Author(s) : DA ROS S.
Summary
An analytical investigation has been carried out to determine the optimal working conditions for a carbon dioxide transcritical cycle with respect to the typical working conditions of the commercial refrigeration. A cycle with flash gas removal has been considered where the throttling is accomplished in two separate stages. The COP has been maximized by varying the value of the high side pressure for a wide range of temperatures at the outlet of the gas cooler. Also the ratio between the mass flow rate for the main compressor and that for the auxiliary compressor have been changed independently, affecting the value of the pressure within the liquid separator. Two different systems are compared in order to find the best solution to put into practice.
