When the indoor temperature is lower than 12℃, people will feel cold. The average indoor temperature in winter in South China is only 6.5℃. When the air humidity increases by 10%, the temperature felt by human body will decrease by 1℃, and the average humidity in southern winter is 75% (only 25% in northern winter).
So the temperature in the south is 6.5℃, but the temperature felt by human body is 2.5℃. This wet cold is worse than the dry cold in the north. It is particularly necessary to install floor heating in southern families.
Extended data:
Floor heating is short for radiant floor heating, and English is radiant floor heating. It takes the whole floor as the radiator, heats the whole floor evenly through the heat medium in the radiant layer of the floor, and conducts it from bottom to top by using the law that the floor itself accumulates heat and radiates upwards, thus achieving the purpose of heating.
Water heating system refers to a heating method that heats water to a certain temperature, transports it to the water pipe cooling network under the floor, and realizes the heating purpose through floor heating.
The low-temperature geothermal medium forms a gradually decreasing temperature gradient from the sole of the foot to the head indoors, which gives people the comfort of warming their feet and cooling their heads. Radiant floor heating conforms to the fitness theory of "warm feet and cool roof" in traditional Chinese medicine. It is the most comfortable heating method at present and a symbol of modern life quality.
According to the quality of heat medium, it can be divided into circulating system and electric floor heating, and according to the pavement structure, it can be divided into wet floor heating and dry floor heating. Dry floor heating does not need to be backfilled with peas. From the perspective of surface decoration materials, it can be divided into floor floor heating and floor tile floor heating. Functionally divided into ordinary floor heating and far infrared floor heating.
New floor heating-1,carbon crystal floor heating 23 degree ecological floor heating is recognized as carbon crystal floor heating by professional departments. Carbon crystal electric heating plate is a heating element made of carbon fiber modified into carbon crystal particles and synthesized with special polymer resin materials.
Its heating principle is that under the excitation of electric field, carbon molecular groups generate Brownian motion in the heating body, and the heat energy generated by collision and friction between carbon molecular groups is transferred to the outside in the form of far infrared radiation and convection, in which the heat energy of far infrared radiation reaches more than 65% and the heat energy of conduction reaches more than 30%. The conversion rate of electric energy and heat energy is over 98%. ?
The product has the characteristics of high efficiency, energy saving, economy, no pollution, long service life and controllable temperature, and the use cost is only about half of that of ordinary electric heating products. Therefore, the application prospect of carbon crystal technology is very broad. Heating can replace the traditional heating mode with high energy consumption, high pollution and high waste, and has a very broad application prospect in the fields of military, aerospace, snow melting in airports in extremely cold areas, snow melting on roofs, outdoor heat preservation and heating.
