“…Almost one third of the chemical energy of the fuel is carried away by the exhaust stream of the vehicle [15][16][17] and another one third by the coolant loop and this has attracted considerable research in making use of the residual thermal energy available from the vehicle to drive the VARS. On the vehicle, the VARS can either be used for a refrigeration system or for an air conditioning system.…”

“…Boatto et al [17,29] discussed a more pragmatic approach for developing VARS as an alternate to the VC system for air conditioning. They stated that every part must be designed and manufactured with appropriate functional and geometrical characteristics owing to the limited space available on the vehicle and retrofitting commercially available VARS on the vehicle was not preferred.…”

“…A requested nominal cooling power of 2 kW corresponds to a generator power supply of some 4 kW. Previous experimental tests on the exhaust system of a 2 l spark-ignition engine allowed the available exhaust power to be correlated with the running conditions [13]. The available thermal power is given in Fig.…”

An automotive air conditioning system based on absorption cycles has been studied. Such a system uses the recovered heat available in the engine exhaust gas. The lithium bromide±water pair is recommended as the working mixture owing to its present technological application level. A possible arrangement of the absorption system for this purpose is proposed. The suitability of such a system has been investigated, taking operating conditions and other standard requirements into account. Finally, the particular features of the proposed scheme are pointed out, and a borderline (at least in stationary conditions) is located in the power±velocity diagram.

“…Several methods were applied for recovering waste heat from exhaust gases of the internal combustion engines [5,6]. The researchers claimed that utilizing exhaust gas waste heat received from engines in the VAR systems could be an alternative for cooling applications [7,8]. When using the VAR system driven by waste heat of exhaust gas, some applications require low temperature refrigeration such as the truck refrigeration system used for preserving the perishable food during the transportation.…”

“…Another experimental research work were conducted on the application of a low-temperature refrigeration system by Horuz [10], who aimed to investigate the performance of a VAR system driven by waste heat received from exhaust gases under different conditions. Many other researchers [11,12] studied VAR systems driven by waste heat from exhaust gas for air-conditioning vehicle cabins. They all confirmed the feasibility of the VAR system application.…”

A Vapor Absorption Refrigeration (VAR) system driven by the exhaust gas waste heat received from the internal combustion engine of an intercity bus is modeled and analyzed for air-conditioning the intercity bus cabin under different operating parameters. Initially, the hourly comfort cooling load of the intercity bus is calculated for a cooling season spanning five months between May and October in Turkey. After determining the capacity of heat source sufficiency for air-conditioning the intercity bus, energy and exergy analyses of the VAR system are conducted, then designed and compared with the vapor compression refrigeration system in respect to the effect of fuel consumption. The results show that approximately 4,489 kg/year of fuel can be saved by using the VAR system driven by an exhaust gas waste heat in an intercity bus. The maximum coefficient of performance (COP) of the VAR system is obtained as 0.78 at 5 a.m. in May, and the maximum total exergy destruction for the VAR system is obtained as 15.25 kW at 4 p.m. in July. Lastly, the specific time is selected to investigate the effect of operating and environmental parameters on the VAR system.
