The invention discloses a multi-branch indoor heat exchanger for synchronous heat exchange. The multi-branch indoor heat exchanger comprises a super cooling coil, a multi-branch heat exchange coil, an over-heating coil and a fan, wherein the super cooling coil and the over-heating coil are arranged at the positions with the best heat exchange effect and the poorest heat exchange effect in the indoor heat exchanger respectively and are parallel to the multi-branch heat exchange coil; a refrigeration outlet of the super cooling coil is connected with a refrigeration inlet of the multi-branch heat exchange coil; and a refrigeration outlet of the multi-branch heat exchange coil is connected with a refrigeration inlet of the over-heating coil. The equipment provided by the invention is suitable for various types of air conditioning systems; the stability and the reliability for working of an expansion valve can be effectively enhanced; a compressor is prevented from performing wet compression; and the efficiency of the system and the safety and the reliability for operation are effectively improved.
