Analysis of heat recovery system for air-conditioning application in motor yachts

Combustion engine is a primary source for electric energy consumed in all electrical devices in ships and yachts. Conversion of fuel energy into mechanical and electrical energy is related to creation of a significant amount of heat, which is irretrievably removed. Ejection system can be effectively driven by low-grade heat source such as waste heat from the engine. The paper presents analytical analysis of thermal-flow operating parameters of waste heat node used for small yachts air-conditioning systems. The results show that such solution can produce 15 kW of cold consuming 70 kW of heat at temperature of 120 ºC. Cooling capacity of 15 kW should satisfy cooling demand of small- and mid-size yachts.
