Floor heating is geothermal radiant heating. It is a heating method that buries hot water or heating cables with a temperature no higher than 60°C in a coil system under the geothermal floor to heat the entire floor and radiate heat evenly into the room. . Floor heating is a new heating method that has begun to emerge in my country in recent years. Our government has listed floor heating as a key building energy-saving technology for promotion and application. From the perspective of development prospects, more than 60% of future residential heating will use floor heating. The application prospects are promising and there is a huge development market. HT foam concrete floor heating material is a foam concrete insulation material made with special foaming agent, cement and auxiliary materials in appropriate proportions.
Floor heating foam concrete is our company A new type of high-quality foam concrete thermal insulation material developed by the company is a patented product and has been strongly supported and promoted by China Engineering Construction Industry Association, China Construction Standards Committee and other units. Our company has developed a new floor heating insulation layer construction method through technological transformation. The physical quality of the products produced by this method complies with Q/NHW01-2007. The energy-saving index exceeds 30% of the energy-saving index for civil buildings in Henan Province.
Floor heating foam concrete thermal insulation Material product features:
(1) Good thermal insulation performance: its thermal conductivity The coefficient is lower than 0.20W/(m.k).
(2), heat-resistant High degree. The heat resistance can reach above 400℃, there is no thermal decomposition, and it will not cause thermal insulation failure.
(3), green and environmentally friendly ,toxic free and safe. Foam concrete does not contain any toxic ingredients, and the foaming agent and various admixtures have no volatile harmful substances, which is beneficial to the indoor environment.
(4) Carrying capacity powerful. The compressive strength is 0.6~0.8 MPa, and the compressive resistance is better.
(5) Cost of use Low. The cost is 30% to 40% lower than polystyrene foam, which has obvious economic advantages.
(3). The temperature difference between supply and return water: should not be greater than 10 degrees.
(4). The flow rate of hot water in the heating pipe: should be controlled at 0.25-0.5m/s.
(5), geothermal radiation Heating structure thickness: 50-80mm (excluding the thickness of the leveling layer and ground decorative layer), of which the insulation layer is 30-50 mm and the filling layer is 25-30 mm.
(6) Geothermal radiation Heating layer structural weight: 70-120kg/m2.
(7), each ring The length of the road heating pipe should be controlled at 60-80 meters, and the longest should not exceed 100 meters.
(8), ground temperature Control: The ground temperature where people stay for a long time should be controlled at 24-26 degrees, the ground temperature where people stay for a long and short time should be controlled at 28-30 degrees, and the ground temperature in areas where no people stay should be controlled at 35-40 degrees.
(7). The length of each loop heating tube should be controlled at 60-80 meters. The length should not exceed 100 meters.
(8), ground temperature Control: The ground temperature where people stay for a long time should be controlled at 24-26 degrees, the ground temperature where people stay for a long and short time should be controlled at 28-30 degrees, and the ground temperature in areas where no people stay should be controlled at 35-40 degrees. </p
