Analysis Models

Energy consumption analysis models of ship energy system were established. The performance indexes, such as energy loss ratio, waste heat recovery rate and waste heat recovery perfect degree were defined. A 70000 - ton crude oil carrier was taken as an example for energy consumption analysis. The results show that the waste heat recovery rate of exhaust smoke was 15.69%, and the waste heat recovery perfect degree was 52.76%.

Water Heating

In this paper, a heat pump water heating system with waste heat recovery in ammonia refrigeration system was put forward, based on the practical project analysis of energy demand and waste heat emission. Based on the operating characteristics of ammonia refrigeration system, the ammonia heat exchanger was designed to be installed in series on the ammonia main pipe, which can ensure the system operate efficiently and reliably. Through the analysis of measured data, significant economic benefits had been brought about by using the heat pump water heating system. This project can save 2.19 million RMB in annual operating cost, and the investment recovery period will be only 1.5 years. The heat pump water heating system has excellent development prospect.
