A complex heat exchanger capable of working in different air conditioning modes by controlling flow of coolant in a refrigerant-coolant secondary loop system linked with a primary loop of refrigerant circulation. The heat exchanger is capable to perform heating or cooling operation with the flowing coolant being heated or cooled by the refrigerant, while two heat exchanger cores are disposed in parallel, and a path regulating manifold is provided to connect inlet and discharge ports to allow the coolant to flow sequentially or independently through two heat exchangers. In cooling or heating mode, coolant flows sequentially through two heat exchangers to maximize the heat exchange efficiency. In a dehumidifying mode, the low-temperature coolant and the high-temperature coolant respectively flow through the two heat exchangers independently to smoothly implement the dehumidification. Therefore, the single complex heat exchanger can perform the heating, cooling, and dehumidifying operations with maximum efficiency.
