Series-parallel combined cycle efficient heat exchange system

The invention discloses a series-parallel combined cycle efficient heat exchange system, belongs to a series-parallel combined cycle efficient heat exchange system in a gas storage heat exchange system, and aims at solving the technical problems that in the prior art, the flow change is large, and the superheat degree fluctuates. Comprising a heat exchanger C, a heat exchanger B, a heat exchanger A, an air inlet pipe, an exhaust pipe, a condensate pipe, a heat recovery water inlet pipe and a heat recovery water outlet pipe, each of the heat exchanger C, the heat exchanger B and the heat exchanger A is provided with an air inlet, an air outlet, a condensate water outlet, a water inlet and a water outlet, and the air inlets are communicated with the air inlet pipe after being gathered; the exhaust ports are communicated with an exhaust pipe after being gathered; the condensed water outlets are communicated with a condensed water pipe after being gathered, the water inlets are communicated with a heat recovery w
