The invention supplies a minitype energy saving adiabatic fuel gas absorption air conditioning, comprising high voltage generator, low voltage generator, high temperature heat exchanger, low temperature heat exchanger, condenser, evaporator, absorption machine, air cooling machine, liquid pump and recycling pump. Residual heat of saturated cryogen of heat exchanger outlet of low voltage generator is recovered in low temperature heat exchanger, cryogen condenser and absorber liquid cooler both use air patenting method, absorber without heat exchanger in it has packing within. The heat transfer and mass transfer course is strengthened by using air patenting adiabatic absorption to divide the course into steps, and surface square of absorber is reduced, solving the problem exist in falling film of air patenting pipe and ensuring the system operating reliable and energy-saving, in addition , it avoids potential danger of refrigerant in electricity driving air conditioning, reducing electric power hill and dale difference in summer, eliminates all disadvantages exist in water cooling fuel gas air conditioning, it is safe and healthy, easy to control and has a wide use.
