Description

High-efficiency heat-transfer heating floor

Technical Field

The utility model relates to a floor and the method of mating formation, specifically speaking, the utility model relates to a but built-in little heat pipe's heating floor and the method of mating formation.

Background

With the improvement of the life quality of people, the design requirements of people on houses for living are higher and higher. At present, most of rooms are not provided with obvious and exposed heating pipelines and radiators, and floor heating is basically adopted.

The floor heating is short for floor radiation heating, the whole floor is used as a radiator, the whole floor is uniformly heated through a heating medium in a floor radiation layer, and the heat conduction from bottom to top to the indoor is carried out by utilizing the principle of heat storage and upward radiation of the floor.

The ground radiation heating is mainly divided into water floor heating and electric floor heating according to different heating modes. The water floor heating is characterized in that a water pipe is coiled in an interlayer of a floor, hot water with the temperature not higher than 60 ℃ is heated by heating water in the water pipe, the floor is heated by means of the circulating flow of the hot water in the water pipe, and heat is supplied to the indoor through the ground in a radiation (main) and convection (secondary) heat transfer mode. In the electric floor heating, a low-temperature heating cable is laid in a floor interlayer, the floor is heated through the low-temperature heating cable, and then the floor is heated indoors through the ground in a radiation (main) and convection (secondary) heat transfer mode.

The advantage of floor heating: 1. comfortable, sanitary and health-care. The ground radiation heating is the most comfortable heating mode, the temperature of the indoor ground surface is uniform, the room temperature is gradually decreased from bottom to top, and people can feel that feet are warm and cool when feet step on a warm floor; improving blood circulation and promoting metabolism; the convection of the dirty air is not easy to be caused, and the indoor air is clean. 2. Saving space and beautifying rooms: the radiator and the branch pipe thereof are eliminated indoors, the use area is increased, the decoration and the household arrangement are convenient, and the sanitary dead angle is reduced. 3. High-efficiency and energy-saving: the radiation heating mode has higher heat efficiency than the convection heating mode, and the heat is concentrated in the height beneficial to the human body; the heat loss in the transmission process is small; the low-temperature ground radiation heating can be controlled in a layered, household and chamber-by-chamber mode, and users can regulate and control according to conditions, so that energy is effectively saved. 4. The thermal stability is good: the ground heating ground layer and the concrete layer have large heat storage capacity and good thermal stability, and the indoor temperature changes slowly under the condition of intermittent heating.

However, at present, there is a fatal determination for such a heating method: 1. maintenance is troublesome: no matter warm water or warm electricity, all need when building the house, pre-buried water pipe or cable in indoor floor intermediate layer in advance, then, lay ground again. When people take in a house for decoration, the floor tiles or the floor are paved on the ground, so once a water pipe of a water floor heating system or a low-temperature heating cable of an electric floor heating system fails, when the water floor heating system cannot normally heat, the floor tiles or the floor with a large area need to be damaged, a floor layer is damaged, a fault point is searched, and maintenance is carried out, so that the house is high in destructiveness and troublesome in maintenance. 2. Early construction/installation costs are high. 3. Keels and pipelines need to be laid, the height of the house is reduced, and the quality of life is sacrificed. 4. The use cost is high. For water floor heating, a heating coil pipe under a floor needs to be cleaned and maintained regularly (2-3 years), so that water scales are prevented from being accumulated in the water pipe, and the heating effect is prevented from being influenced. The low-temperature heating cable for electric heating needs to be checked for leakage, and once the cable is found to be aged, the cable needs to be replaced completely.
