The invention discloses a passenger car air conditioner and a defrosting control method, device and equipment thereof and a medium, the passenger car air conditioner comprises a compressor, an external heat exchanger, an internal heat exchanger, a multi-way valve, a gas-liquid separator, a first throttling element and a battery heat exchange auxiliary road, and the battery heat exchange auxiliary road comprises a second throttling element and a battery heat exchanger. The compressor, the multi-way valve, the external heat exchanger, the first throttling element, the internal heat exchanger, the multi-way valve, the gas-liquid separator and the compressor are sequentially connected, the second throttling element is connected with the first throttling element and the external heat exchanger, and the second throttling element, the battery heat exchanger and the multi-way valve are sequentially connected. During defrosting, the compressor communicates with the external heat exchanger and the internal heat exchanger through the multi-way valve, and the battery heat exchanger communicates with the gas-liquid separator through the multi-way valve. According to the invention, the inner heat exchanger and the outer heat exchanger can heat simultaneously during frosting, so that the passenger cabin can be heated continuously while the defrosting effect is achieved, and the comfort of passengers in a vehicle in winter is kept.
