Thermodynamic analysis of the two-phase ejector air-conditioning system for buses
Applied Thermal Engineering, 2015 Air-conditioning compressors of the buses are usually operated with the power taken from the engine of the buses. Therefore, an improvement in the air-conditioning system will reduce the fuel consumption of the buses. The improvement in the coefficient of performance (COP) of the air-conditioning system can be provided by using the two-phase ejector as

Optimal thermodynamic parameters of two-phase ejector refrigeration system for buses
Applied Thermal Engineering, 2017 Abstract Air-conditioning is necessary for the comfort of passengers in commercial buses. However, installing an air-conditioning system can add extra load on the engine and result in extra fuel cost. Therefore, an improvement in the air-conditioning system can lower the fuel consumption of the buses and reduce the size of the evaporator and the ...
