The invention provides a heat exchange system, an oil return temperature control method, a readable storage medium and a controller, the heat exchange system comprises a compressor, a first heat exchanger and a second heat exchanger which are connected in series, and a battery cooler and a regulating valve which are connected between an outlet of the first heat exchanger and an inlet of the compressor in series; the regulating valve and the controller are connected with the battery cooler and the first heat exchanger. The controller obtains the working state information of the compressor, and in a refrigeration mode, if the operation rotating speed of the compressor is lower than the set rotating speed and the operation duration reaches the first duration, the adjusting valve is controlled to be opened, and the compressor is controlled to operate at the oil return rotating speed, so that refrigerant oil flowing out of an outlet of the first heat exchanger flows into the compressor through the adjusting valve; when the flow speed of the refrigerant oil in the heat exchange system is increased, the reversing inlet of the reversing valve is controlled to be at least communicated with the second reversing outlet, so that the heat load in the refrigerating fluid flows into the battery cooler, and the sudden drop of the air outlet temperature is prevented.

    本申请提供一种换热系统、回油控温方法、可读存储介质及控制器,换热系统包括串联连接的压缩机、第一换热器和第二换热器,串联连接于第一换热器的出口和压缩机的入口之间的电池冷却器和调节阀,与电池冷却器、第一换热器连接的调节阀及控制器。控制器获取压缩机的工作状态信息,并且在制冷模式下,若压缩机的运行转速低于设定转速且运行时长达到第一时长时,控制调节阀打开,并控制压缩机以回油转速运行,使从第一换热器的出口流出的冷冻油通过调节阀流入压缩机,来提高换热系统内冷冻油的流速,通过在提高换热系统内冷冻油的流速时,控制换向阀的换向入口至少与第二换向出口连通,使得冷冻液中的热负荷流入电池冷却器,防止出风温度骤降。
