[0025] A water distribution system is provided between the liquid outlet main pipe and the liquid return main pipe, and the medium flows to the water distribution system. The water distribution system includes a wind disk liquid distributor 3 and a floor heating liquid distributor 9 arranged in parallel.

After heating the room first, the medium flows back to the buffer tank along the corresponding first liquid return branch 121, and continues to flow back to the air source heat pump for continuous circulation.

[0037] At the same time, the medium flows along the corresponding second liquid outlet branch to the corresponding floor heating coil 8, the floor heating coil 8 heats the indoor floor and transfers heat to the indoor air. The medium flows back to the buffer tank 10 along the corresponding second liquid return branch, and continues to flow back to the air source heat pump for continuous circulation.

[0038] Example 4
