2, the second heat exchanger 3, the First Heat Exchanger 2 are in the first area of the radiant panel 1, and second heat exchanger 3 is in institute
The second area of radiant panel 1 is stated, the second area is surrounded on around the first area, and the first area is in institute
Radiant panel 1 is stated back to conditioned space side.It should be understood that the outside cold and heat source apparatus 100 is used as the indoor spoke
It penetrates the cooling capacity of end or the feed unit of heat and designs, such as it can be the outdoor unit similar to conventional air conditioner,
It can be the set of corresponding Cooling and Heat Source unit such as water cooler, the present invention is not specially limited, as the outside Cooling and Heat Source
A kind of common design form of device 100, as shown in Figure 1, that includes compressor 103, outdoor heat exchanger 106, throttling dresses
The air-conditioning systems main components such as 107 (such as electric expansion valves) and three-way diverter valve 105 are set, to pass through above-mentioned described first
It is empty that the respective line of refrigerant pipeline 101, the second refrigerant pipeline 102 and the indoor radiation tail end is connected to become the radiant type
Adjusting system.The radiant panel 1 for example can be the floor in conditioned space either tile body, the present invention and also not do special limit
It is fixed, that is, no matter the radiation-type air conditioner system of the invention is applied to floor or the furred ceiling of building, it all can solve this hair
Bright technical problem to be solved.First area above-mentioned is the specific can be that floor (furred ceiling) occupy conditioned space (room)
Middle position, and second area then can be the marginal position that floor (furred ceiling) occupy conditioned space (room), such as floor (is hung
