Abstract
This paper presents a novel idea of integrating a refrigeration and power system using Organic Rankine cycle (ORC) and solid sorption technology into Internal Combustion Engine (ICE). A 1-D engine model has been coded to evaluate the waste heat quantity of a medium-duty diesel engine. The recoverable waste heat from the coolant and exhaust system has been analysed under engine overall operational region. Based on these results, the working conditions of a cogeneration are designed and the performance of the cogeneration is evaluated throughout the engine operating region. Results indicate that the maximum recoverable from the coolant and exhaust system is 67.9 kW and 82.7 kW, respectively. Meanwhile, the cogeneration can provide the power of 13.88 kW and refrigeration of 16.58 kW at the engine rated point. This system has the potential to improve the overall energy efficiency of the ICE from 40% to 47% and reduce the average brake specific fuel consumption (BSFC) from 205 g/kWh to 180 g/kWh at full load conditions.
