“…It was concluded that by dynamically controlling the amount of heat input, the range of uses of the absorption refrigeration system powered by the heat of the exhaust gases can be expanded. Abu-Ein et al (2009) presents an exergetic analysis of a refrigeration system by absorbing water-ammonia 10 kW, whose energy source is solar. They obtained the coefficient of performance (COP), exergetic coefficient of performance (ECOP) and the loss of exergy (dE) in each of system components for varying operating conditions.…”

This paper examines the available heat of internal combustion diesel engines for activating automotive air conditioning systems with an absorption refrigeration cycle using ammonia-water pair. Firstly, an exergetic study was carried out of both the engine and absorption cycles working together, to assess the technical feasibility of using this system for air-conditioning vehicles for public transport. The modeling and simulation were developed through algorithms on the Engineering Equation Solver platform, taking into account mass balance, the first and second laws of Thermodynamics, identifying tailings and losses in the thermal system. The simulation of the internal combustion engine is modeled for the flexibility of biodiesel, to provide an energy and exergy analysis depending on the type of fuel used in the engine. It was possible to analyze the effects that variations in the engine exhaust gases can cause in the refrigeration cycle and to determine the thermodynamic state in the refrigeration cycle, the behavior of the coefficient of performance, refrigerated power and exergy distributed in function of the variation in the condensation and evaporation temperature, and the conditions of gases in the generator.

This study demonstrated the feasibility of an absorption refrigeration system (ARS) that is capable of utilising the engine exhaust gas of bulk gas carriers as the heat source and generating cooling source either for reliquefaction of the boil-off gas (BOG) or for heating, ventilating and air conditioning. The ARS employed an NH 3 /H 2 O mixture as the working fluid. The process was designed and simulated using the properties of the exhaust gas from the commercially available engines. The coefficient of performance increased with the temperature of the generated cooling source. A decrease in the engine load resulted in a decrease in the exhaust flow rate and, consequently, in a decrease in the cooling capacity. Although the exhaust temperature reached its minimum around the normal continuous rating, the dependence of the cooling capacity on the engine load was not significantly affected. A case study for a liquefied natural gas carrier verified that the refrigeration system afforded a sufficient cooling capacity to satisfy both the required work and the temperature level needed for reliquefaction of the BOG.

Solar energy is an important source of renewable energy. In this paper, renewable energy is used to cooling purpose in the Middle East. The cooling load is calculated for major cities of the Middle East. An ammonia absorption refrigeration cycle (AARC) is used for cooling purpose. Solar energy is used as the source of high temperature. Codes are written in EES software to analysis the solar cooling cycle. In this analysis, temperature, enthalpy, and other thermodynamic properties are obtained in different cases. Weather properties information such as winter and summer design temperatures of these cities are obtained from HVAC handbooks. The variation of temperature and cooling capacity in different months and different hours of a day is calculated and is shown in different figures. Cooling ability of solar cooling system varies in the different month and different hours. Furthermore, the influence of the efficiency of heat exchanger of solar cooling system on the coefficient of performance of cycle and the cooling capacity is investigated. In this paper, different climates with summer design dry bulb between 32º C and 47º C and solar heat gain between 840 w/m 2 and 890 w/m 2 are considered.
