Claim:
1. An integral air conditioning system for heating and cooling, the integral air conditioning system comprising: an air conditioner comprising a first compressor and a first indoor heat exchanger, the air conditioner forming a first refrigeration cycle; a cooler comprising a second compressor and a second indoor heat exchanger, the cooler forming a second refrigeration cycle; an outdoor heat exchanger comprising a first heat exchange part being part of the first refrigeration cycle and a second heat exchange part being part of the second refrigeration cycle; a blower fan for blowing outdoor air into the first heat exchange part and the second heat exchange part; a sensing part being adapted to detect a pressure and/or temperature of a refrigerant circulating in the second refrigeration cycle; a branch part comprising a plurality of branches for dividing the refrigerant to be introduced into the second heat exchange part; a plurality of valves disposed in the branches of the branch part; and a control unit configured to compare the detection value received from the sensing part with a preset value, and configured to control the flow of refrigerant through the branches into the second heat exchange part depending on the comparison result, wherein the control unit is configured to control the plurality of valves in accordance with a plurality of valve adjustment stages being previously set, wherein each of the valve adjustment stages represents an open degree of the plurality of valves, wherein the plurality of valve adjustment stages is ranked according to the amount of the refrigerant condensed in each stage, wherein the higher the stage number is in the ranking, the lower is the pressure or temperature of the refrigerant being introduced into the second heat exchange part, wherein the smaller an open degree of the plurality of valves is, the lower ranked is the valve adjustment stage in the ranking of the plurality of valve adjustment stages, wherein the second heat exchange part comprises: wherein the branch part comprises: wherein the plurality of valves comprise:
