Wherein, Part III changes heat treated idiographic flow: under the power drive of blower fan, indoor return air is inhaled in intake stack and mixes with new wind air inlet pipe from return air air inlet pipe respectively with outdoor new wind, form mixing air, first mixing air filters mixing air through filter, then mixing air enters in the ventilation gap of radiant panel from the heat exchanging chamber air inlet of radiant panel, and flow to the heat exchanging chamber air outlet of radiant panel, in the flow process of mixing air in radiant panel ventilation gap, be the heat convection state of adverse current with the flow of hot water in heat exchanging water pipe, the mixing air being heated after heating up is from the heat exchanging chamber air outlet of radiant panel flows out, send into indoor through air-supply escape pipe, promote indoor environment temperature.
