An absorption-type air conditioner core structure is provided, which uses lithium bromide solution as absorbent and has a small volume and compact structure. The air conditioner core structure includes an upper vessel (24) and a lower vessel (21). The upper vessel and lower vessel are connected by a refrigerant water pipe (22), a cooling water pipe (7), a heating steam pipe (5), two concentrate solution pipes (27, 58) and two dilute solution pipes (46, 52). The concentrate solution and dilute solution pipes are disposed within a solution pipe protecting cover (23) which connects to both vessels. Because of its compact structure, small volume, fewer welding seams, high level of vacuum, and having the heat exchange pipes (30, 39, 61, 73) of the condenser 1, low temperature generator 2, evaporator 10 and absorber 11 all made of helical copper pipes, the air conditioner core structure has high heat exchange efficiency.
