<p>and cooling surface, in the surrounding air, with the walls, roof, shed external envelope structure of radiant heat exchange, so that the surrounding envelope surface temperature. At the same time, the direct radiation heat transfer between the human body and the human body reduces the radiation heat loss. This makes the heating floor has the following prominent advantages: (1) compared with other heating methods, the ground temperature is much higher, and </p>
<p>the indoor is surrounded by the supporting structure of the inner surface temperature increase, reduce the cold wall radiation on the human body. Because of the dual function of radiation intensity and temperature, the thermal state which accords with the comfort requirement of human body is created, and the comfort of human body is improved. (2) the radiation heat dissipation of all kinds of rooms has greatly exceeded the required values of human metabolic </p>
<p>rate under different activities, and fully meets the physiological needs of the human body and meets the requirements of thermal comfort. (3) the heat produced by the floor heating is transmitted by radiation, which will not lead to the rapid flow of indoor air, thus reducing the possibility of dust flying and improving the sanitary conditions. 2, improve the blood circulation of the human body to warm the floor is a carbon fiber heating cable is energized, the electrical </p>
