Résumé

Ships have abundant waste heat which can be recovered to act as the driving heat source for the ejector refrigeration and desiccant air-conditioning (A/C) systems. In this paper a novel marine ejector-refrigeration rotary-desiccant A/C system is proposed and its configuration and working principle are introduced in detail. The novel A/C system driven totally by ship’s waste heat is composed of an ejector-refrigeration unit and a rotary-desiccant A/C sub-system. The A/C system has some excellent advantages to apply on ship such as the independent temperature and humidity control and energy saving. Taking into account the thermal quality of ship’s waste heat, the special ambient environment including the cooling sea water readily available overboard, and the specific working conditions for the A/C system proposed, some environment-friendly working fluids or refrigerants are compared and analyzed for the system’s ejector refrigeration unit. It can be concluded that water should be the most suitable working fluid for the A/C system proposed.
