Disclosed is a radiant floor heating multi-split air conditioning system, which comprises: an outdoor unit; an indoor unit which is connected to the outdoor unit through a refrigerant pipeline; and a controller which is respectively connected to the outdoor unit and the indoor unit through shielding signal lines. The air conditioning system further comprises a radiant floor heating pipe group, wherein the radiant floor heating pipe group comprises a composite radiant floor heating pipe, a third stop valve, a third filter, a third electronic expansion valve, a fourth stop valve and a radiant floor heating pipe group control panel. In a refrigerant inflow direction, the third stop valve, the third filter and the third electronic expansion valve are arranged together on the refrigerant pipeline which is connected to a refrigerant inflow end of the composite radiant floor heating pipe; the third electronic expansion valve is electrically connected to the radiant floor heating pipe group control panel; and the radiant floor heating pipe group control panel is connected to the controller through a shielding signal line. The radiant floor heating multi-split air conditioning system can accurately control temperature during heating, thereby reducing energy consumption, and can stop heating if there is no heating requirement, thereby preventing cracking of the radiant floor heating pipe due to frost. |
