When heating in winter, water in a system pipeline can be preheated by an air conditioner external unit, the preheated water is heated to a higher temperature by a gas water heater, the heated water flows into an indoor fan coil, and after wind absorbed from the indoor blows over a high-temperature coil fin, the heated air can be sent into the indoor space, so that the purpose of heating is achieved. The air conditioner main machine is used for preheating firstly, and then the gas water heater is used for heating, so that firstly, the gas price is far lower than the electricity fee, and meanwhile, the price of the gas heat exchanger is lower than that of the compressor. Secondly, because the unified air supply and air exhaust is adopted, the fan of the indoor fan coil is cancelled, so that when the number of indoor units is large, the cost of accessories is low. Finally, because the indoor fan coil adopts a fan-free structure, the air quantity at the tail end is small, although the effect on the temperature rise and drop speed is slight, the comfort level is greatly improved, and the air feeder and the exhaust fan can be arranged outdoors, so that the noise is basically avoided indoors.
