Abstract: An intelligent energy-saving air conditioner includes a control device (1), a heat-exchange circulation system (2), a refrigerating system (3), and an inner air blower (41) and outer air blower (42) both are shared by the heat-exchange circulation system (2) and the refrigerating system (3). The control device (1) includes a temperature collecting and comparing unit and a control unit. The heat-exchange circulation system (2) includes a first heat exchanger (21) and a second heat exchanger (22) separately arranged from each other, and heat-exchange circulation pipes (24) connecting the first and second heat exchangers (21), (22). The refrigerating system (3) includes an evaporator (31), a condenser (32), a compressor (33) and refrigerating circulation pipes (34) connecting the evaporator (31), the condenser (32) and the compressor (33).
