Analysis on the structure and characteristics of ground radiant heating

Ground radiation heating is to make the room warm by radiation on the ground, and the temperature is from bottom to top, making people feel more comfortable Structure form 1 Ground boat pipe It mainly uses heat resistant, pressure resistant, corrosion-resistant and anti-aging XLPE cross linked pipes It has small water resistance and long service life of 60 years It saves metal and pipes, and has no interface and no leakage under the ground floor On the ground surface of the building, the insulation material shall be laid first; the cross-linked pipe with a length of 120-150m shall be fixed on the insulation material at a certain distance by special two-way circulation Then backfill the pea stone concrete, and make the ground layer after tamping and leveling (the material is unlimited, which can be marble, brick, wood floor, carpet, etc.) In order to prevent concrete cracking, additives and expansion joint materials should be added in construction The heat medium can be used as other heating return water, air conditioning return water, residual hot water, geothermal water, or self-contained system after heat exchange, with the water temperature lower than 50 ℃ The low-temperature hot water is circulated in the cross-linked pipe by the low-pressure micro pump, heating the surface layer and radiating heat transfer 2 Geothermal cable The utility model takes the metal wire as the heating element, the EVA heat-resistant material as the insulator, the tinned braided copper wire as the shield, the plastic protective belt extrusion molding outer sleeve (CSP), after being electrified, generates the infrared radiation wave, which is transmitted to the ground, and then radiates to the room to achieve the heating purpose The ground temperature is 26-32 ℃, and the room temperature can reach 18-25 ℃ 3 Ground heating plate There are carbon fiber heater with aluminum alloy shell, and electric heating plate compounded with steel plate through polyurethane foaming process, which is laid on the thermal insulation layer on the cement base surface, and then covered with the ground decoration layer After power on, the electric heating plate heats up, transfers heat to the ground, and then radiates to the indoor heating 4 Ground heating film Some with aggrandizement compound floor cooperates use Some of them inlay the electric heating film in the wood floor slot, once in place, and the construction is simple and convenient Features: 1 The room temperature is from bottom to top, and the temperature gradient is appropriate, which makes people warm their feet and cool their heads It is a comfortable heating way for Zui 2 It does not occupy the ground and can make full use of the indoor effective area However, the floor is thickened and the building load is increased 3 Solve the heating problem of long-span and low window buildings 4 Indoor sanitation and fresh air There is no convection of dirty air, no dust, no peculiar smell and no noise 5 Long service life The crosslinking tube can be used for more than 60 years, and the hot cable and hot plate can be used for 30 years 6 Low temperature heating, energy saving The heating effect of 20 ℃ can be achieved by selecting 16 ℃ parameters The coil water pipe can be used for other heating return water, air conditioning return water, residual hot water, geothermal water, etc 7 Safety and security No need to worry about burns and fires 8 Large thermal capacity and good thermal stability When intermittent heating, the temperature changes slowly 9 Simple operation and management, low maintenance and operation cost 10 Some of them radiate far infrared rays and have physical therapy and health care effects on human body.
