At present, ground heating is becoming more and more popular in China, especially in Shandong, Tianjin, Northeast China, Inner Mongolia, Hebei and other places in China. Its application has been quite extensive and widely welcomed by residents. So what are the advantages of floor heating? What are the types of floor heating?

nowadays, ground heating is becoming more and more popular in China, especially in Shandong, Tianjin, Northeast China, Inner Mongolia, Hebei and other places in China. Its application has been quite extensive and is widely welcomed by residents. So what are the advantages of floor heating? What are the types of floor heating? In this issue, the editor will introduce the types of floor heating in detail. Let's get to know it

I. principle of ground heating

ground radiant heating takes the whole ground as the radiator, heats the whole ground evenly through the heat medium in the floor radiant layer, and uses the law of heat storage and upward radiation of the ground to conduct from bottom to top, so as to achieve the purpose of heating

because the temperature gradient from the sole of the foot to the head gradually decreases indoors, it gives people a comfortable feeling of warm feet and cool head, which is in line with traditional Chinese medicine “ Warm feet and cool top ” The fitness theory is the most comfortable heating method at present, and it is also a symbol of the quality of modern life

II. Classification of floor heating

the classification of floor heating is divided into two categories: water floor heating and electric floor heating from the perspective of heat medium, wet floor heating and dry floor heating from the perspective of pavement structure, and floor tile floor heating from the perspective of surface decoration materials; It can be divided into ordinary floor heating and far-infrared floor heating

1. Water floor heating

water floor heating, that is, low-temperature hot water floor radiant heating, is a heating method that takes hot water with a temperature not higher than 60 ℃ as the heat medium, circulates in the heating pipe, heats the floor, and heats the indoor heat through the ground in the form of radiation (primary) and convection (secondary). It has the characteristics of warmth, comfort (even heat dissipation without drying), health, energy saving and so on

water floor heating is divided into dry floor heating and wet floor heating from the pavement structure

(1) dry floor heating

dry floor heating, compared with the installation method of ordinary floor heating that requires backfilling with concrete and other materials, it does not need backfilling, so it is named dry floor heating Because there is no backfill layer, the occupied space is reduced, which is also known as ultra-thin floor heating. The reason why it does not need backfilling is that the coil of the floor heating is stuck in the slot of the insulation board. Due to the ultra-thin characteristics of dry-type floor heating, it is mostly used in rooms with lower floors or rooms with fine decoration

the form of dry-type floor heating is the connected sheet modules. When installing, you only need to put together the pieces of modules according to the designed drawing line and the direction of the floor heating coil, and you can quickly complete the floor heating construction and carry out the floor decoration

the structure of dry-type floor heating module is heat conduction layer, floor heating coil and heat insulation layer. The heat conducting layer is located above the heat insulating layer, and the heat conducting layer is fixedly connected with the heat insulating layer. There is a floor heating coil tank between the two layers, and the floor heating coil tank is inverted ω U-shaped pipe groove. The pipe clamp is omitted, and the glue lamination is not required for fixation, which not only does not occupy the floor height, but also ensures the floor elasticity and good comfort
