1. An air conditioning system with an integrated heat exchanger, the air conditioning system comprising:
a refrigerant circuit through which a refrigerant is circulated, the refrigerant circuit including a compressor, a condenser, an expander, and an evaporator;
a first coolant circuit through which heating coolant exchanging heat with the condenser of the refrigerant circuit is circulated;
a second coolant circuit through which cooling coolant exchanging heat with the evaporator of the refrigerant circuit is circulated;
an indoor heat exchanger which is provided in an air conditioner and to which the first coolant circuit and the second coolant circuit are connected to receive the heating coolant and the cooling coolant and thereby generate heating air or cooling air; and
a valve module to which the first coolant circuit and the second coolant circuit are connected, the valve module configured to control the heating coolant or the cooling coolant circulated in the indoor heat exchanger,
wherein the first coolant circuit comprises a first water pump and an outdoor heat exchanger, and the second coolant circuit comprises a second water pump.
