Description

Phase-change energy storage aerial floor heating structure

Technical Field

The utility model relates to the technical field of buildings, in particular to a phase change energy storage overhead ground heating structure.

Background

The raised floor is paved by a plurality of floor units, and the block-shaped floor is supported by the bracket below, so that a raised layer is formed between the floor units and the concrete floor slab. The cable is originally commonly used in rooms where power systems are arranged, such as machine rooms and computer rooms, cables can pass through an overhead floor space below a floor, and the overhead floor can also prevent static electricity. In recent years, due to the requirement of environmental protection, sand bailing operation is completely forbidden in inland river channels, and the construction mode of a sand cushion layer below a ceramic tile originally used for indoor floor decoration is gradually eliminated; on the other hand, floor heating, household cables and the like are arranged below the raised floor and are accepted by a plurality of people due to the requirements of household comfort and attractiveness; and thirdly, the raised floor is constructed quickly, maintenance is not needed when the raised floor is laid, and the raised floor can be used after being installed and leveled.

On the other hand, the floor heating uses the whole ground as a radiator, the whole ground is uniformly heated through the heating medium in the floor radiation layer, and heat is supplied to the indoor through the ground in a radiation and convection heat transfer mode, so that the purpose of comfortable heating is achieved. Is popular with users in cold regions. Usually, the heating wire pipe is laid on the floor slab, then the floor slab is filled with heat insulation materials, and floor tiles are laid on the heating wire pipe to finish the floor heating construction. The ground heating spool may be formed of a pipe through which a heating medium flows, such as a hot water pipe, or an electric heating wire. Because the floor heating system needs to consume a large amount of heat and has higher energy consumption, the use cost is high.

In recent years, the phase-change material energy storage technology is more and more favored by the architectural decoration industry, and the phase-change material is mainly applied to the aspect of building energy conservation to prepare an envelope structure of a building, a solar phase-change heating and heat storage system and an indoor phase-change air-conditioning and cold storage system. Energy storage is necessary for solving carbon peak reaching and carbon neutralization, a large number of clay walls, brick walls and cement concrete walls are used for energy storage in the traditional buildings, however, modern buildings pursue light weight and high rise, so that steel structures are more, light weight and heat preservation are more, and the materials cannot store energy, so that a large amount of energy is consumed inside to heat or cool, the temperature of people is suitable, the energy storage performance of the phase-change material is 200 times that of the cement concrete, the wall bricks and the soil, and the problems can be solved. The phase change material is a medium like a storage battery, stores heat, and releases energy when needed so as to achieve maximum utilization of the energy. The phase-change heat storage material can be widely applied, and the application of the phase-change material building decoration material has excellent energy-saving and consumption-reducing effects, and accords with the development direction of energy conservation and emission reduction, carbon emission reduction and efficient resource utilization in China.

How to organically combine the raised floor, the floor heating system and the phase change energy storage system to achieve the comprehensive advantages of convenient installation, good sound insulation effect, floor heating, energy conservation, consumption reduction, low use cost and the like of the household floor, and is a problem to be considered by technical personnel in the field.

Therefore, the floor heating system can completely use off-peak electric energy, has a large-capacity energy storage function and saves a large amount of electricity cost. For example, in some cities, the low-valley electricity price is several times different from the high-peak electricity price, if the whole building uses the raised floor structure, the annual saved electricity fee is considerable, and the raised floor structure has very important significance for the stable operation of a power grid.

On the other hand, if the floor heating system is connected to a solar photovoltaic system or a solar water heating system, the solar water heating system can be used for night and day storage to realize zero-carbon heating.

Furthermore, if the energy storage system is used in hot summer, the cold energy at night can be stored in the phase change material, and the cold energy is diffused again when the temperature is higher in the daytime, so that the indoor temperature is balanced, the refrigerating power of the air conditioner is reduced, and the energy is effectively saved.
