In order to reduce the consumption of oil and improve the motivity of the automobile

the authors used the ICE's engine block

cylinder liners

and cylinder headers as the generator of the absorption refrigeration system

and the lithium bromide solution was charged into the engine cooling cavities

which might realize the objective using one single-effect lithium-bromide absorption hot-cold water unit to replace the automobile air conditioning refrigeration and heating system and the automobile engine cooling system. Through the theoretical analysis using thermodynamics

heat transfer

and hydrodynamics

the authors find that it is practical to use this project for its simple and compact structure. This device is of great value to the future research and development of the automobile air conditioning system.
