Description

Dry floor heating system

technical field

The invention relates to the technical field of floor heating, in particular to a dry floor heating system.

Background technique

Floor heating is the abbreviation of radiant floor heating. It uses the whole ground as a radiator, heats the whole ground evenly through the heat medium in the radiant layer of the floor, and uses the heat storage and heat radiation of the ground itself to conduct from bottom to top to achieve The purpose of heating. Compared with traditional heating methods, floor heating is more in line with the law of heat conduction, more conducive to aesthetics, more scientific, and more energy-saving.

From the heat medium, it can be divided into two categories: water floor heating and electric floor heating. Water floor heating refers to a heating method that heats water to a certain temperature, transports it to the water pipe cooling network under the floor, and achieves the purpose of heating through floor heating.

Electric floor heating is a heating method that embeds heating cables or electric heating films whose outer surface allowable working temperature is 65°C in the floor, uses them as a heat source to heat the floor, controls the room temperature or floor temperature with a thermostat, and realizes radiant floor heating.

Water floor heating can be divided into wet floor heating and dry floor heating from the pavement structure. Wet floor heating refers to the use of concrete to embed the floor heating pipes, and then lay floor or floor tiles and other ground decoration materials on the concrete layer. Dry floor heating is a floor heating method that does not use concrete backfill when laying floor heating. Traditional wet floor heating first lays a layer of insulation on the original cement floor, then lays heating pipes on top of the insulation layer, then uses concrete to backfill the heating pipes, and finally installs floors or tiles on top of the concrete backfill layer. The material, plus the ground decoration layer, is generally 8 cm high, which accounts for too much floor height; this kind of wet floor heating is difficult to maintain, it is laid with cement mortar, and the temperature rises slowly after heating; the heat conduction is uneven; the pH value is around 8, and alkali reversion occurs It can reach 12 to 13; the traditional wet floor heating structure is limited by the impact of concrete floor anti-alkali and uneven heat conduction.
