Heat recovery is a common approach for effective energy management. Combustion engine is a main source for electric energy consumed be all electrical devices in ships and yachts. Currently, the classic compressor systems driven by electricity generated in generators are used for production of cold water used in AC units. With utilization of the waste heat the investment and operation costs can be reduced. In the paper a different solutions of waste heat recovery node from flue gases in the maritime industry are discussed. The proposed ejection system is an excellent example of an industrial application with a strong potential for implementation. The paper summarizes the first phase of the project dealing with developing of the ejection air-conditioning system driven by waste heat will be presented. Preliminary calculation of the proposed system operating with low-GWP working fluid will be presented and discussed. The geometry of the ejector designed for the specific case and performance operation line will also be shown.
