The invention discloses a multi-split air source double-
tail-
end system of wall-mounting type duplex
metal radiant panels. The multi-split air source double-
tail-
end system comprises a controller connected with a
heat pump outdoor unit and multiple air conditioner indoor units arranged in multiple rooms, and each room is internally provided with one wall-mounting type duplex
metal radiant panel; each wall-mounting type duplex
metal radiant panel comprises a duplex metal radiant panel body directly wrapping a refrigerating fluid heating
pipe, the outer surface of the wall-mounting type duplex metal radiant panel is coated with an
infrared radiation ceramic coating, the heat transferring effect of a condenser
pipe is improved, and the effect of protecting the
pipe is achieved; and the wall-mounting type duplex metal radiant panels and the air conditioner indoor units are connected in parallel through adjusting
control valves and splitters, the switching states of the adjusting
control valves and the splitters are controlled, and
refrigeration in summer and heating and
defrosting in winter can be achieved. When the multi-split air source double-
tail-
end system is used for heating, the indoor temperature field is evenly distributed, the
heat pump condensing temperature is further reduced, the COP of the air source
heat pump is improved, and energy saving and emission reduction are achieved.
