Absorption heat pump system and process for heating, refrigeration, air conditioning and heat transforming, employing an aqueous buffer solution of a lithium salt therein; an aqueous buffer solution of a lithium salt perfectly neutral in pH useful as a coolant, achieving a very high C.O.P. at a temperature lift much higher than usual, without danger of crystallization, even at high generator temperature (up to 330 DEG C.) and evaporator temperature as low as minus 10 DEG C., while in most cases the absorber and condenser can be economically cooled by (ambient) air.
