Indoor heat exchanger and air conditioning system having the same

Abstract

The utility model provides a kind of indoor heat exchanger and the air conditioning system with it, the reheating heat exchange section of indoor heat exchanger therein has first inlet and second inlet, first inlet is located in the upstream of air inlet direction relative to second inlet, reversing valve has A,B,C,D four valve ports, A valve port is connected in the first pipeline of air conditioning system, B valve port is connected to first inlet, C valve port is connected to second inlet, D valve port is connected in dehumidification heat exchange section by first throttling element, reversing valve has the first state of making A valve port and C valve port conductive, B valve port and D valve port are conducted.Through the control reversing valve is in first state when the utility model is applied to air conditioning system and system runs dehumidification mode, make refrigerant flow into reheating heat exchange section from second inlet and flow out from first inlet, then the flow direction of refrigerant is countercurrent relative to the air inlet direction of reheating heat exchange section, so it can improve the dehumidification energy efficiency of system.
