The invention discloses an air conditioner and refrigerator integrated machine which comprises a compressor, an outdoor heat exchanger, an indoor heat exchanger and a refrigerator. The refrigerator comprises a refrigeration zone and an unfreezing zone, the refrigeration zone comprises a frozen zone and a cold storage zone, the unfreezing zone is arranged in correspondence with the frozen zone, a bypass pipe is connected between the compressor and the unfreezing zone, an exhaust opening of the compressor is connected to an inlet of the unfreezing zone through the bypass pipe, and an air return opening of the compressor is connected to an outlet of the unfreezing zone through the bypass pipe. In addition, an operational control method of the air conditioner and refrigerator integrated machine is provided. According to the air conditioner and refrigerator integrated machine and the operational control method, electric heating unfreezing is not needed, the unfreezing cost can be saved, the unfreezing efficiency can be improved, the unfreezing energy consumption is reduced, and the problems in safety caused by electric leakage are avoided.
