Description

A kind of energy storage system

Technical field

The utility model belongs to household electrical appliance and energy storage, field of energy-saving technology, particularly relates to a kind of technology of energy storage system.

Background technology

Along with people's living standard and to the raising worked and living environment comfort level requires, electric energy etc. consumption is significantly increased thereupon, cause that energy resource consumption is too fast, environmental pollution increase, network load peak valley be excessive, peak load time the building energy consumption such as the supply of electric power wretched insufficiency problem that increases, the building energy consumption of current European and American developed countries has reached 40% of whole society's total energy consumption, about 30 % of national total energy consumption are accounted at China's building energy consumption, along with the development of economy, improving constantly of living standards of the people, the proportion of building energy consumption will increase further.Therefore, the development & application of energy-saving building technology has become one of hot issue of current building and building material field.

Phase-changing energy-storing is the important technology improving efficiency of energy utilization and protection of the environment; also be usually used in alleviating energy supply and demand both sides unmatched effective means on time, intensity and place; be with a wide range of applications in the field such as energy-conservation of the recycling of the utilization of solar energy, " peak load shifting " of electric power, used heat and waste heat, industry and civil buildings and air-conditioning, become worldwide study hotspot at present.Utilizing the latent heat of phase change of phase-change material to realize storage and the utilization of energy, contribute to improving efficiency and exploitation regenerative resource, is a very active forward position research direction in energy science and material science in recent years.

Under current overall situation, the technology such as low-carbon (LC), energy-conserving and environment-protective, accumulation of energy are prior development directions in the world.

On existing market, ice storage air conditioner is a kind of technology of comparative maturity, at developed country's universalness, although water is also kind of a cheap energy storage materials of phase change, but its phase transformation temperature points is subzero, owing to being low temperature ice making, consume energy comparatively speaking larger, improve phase transition temperature fusing point, the phase-changing energy-storing technology especially about 4-7 degree is the research direction of low temperature accumulation of energy from now on.And pure regenerative apparatus, ripe technology is little, and ice storage air conditioner solves the cold-storage problem in summer, but the accumulation of heat problem in winter does not have good technical solution all the time.

Summary of the invention

The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, structure is simple, volume is little, accumulation of energy is large energy storage system.Energy storage system in the technical program is according to the difference of the phase transformation temperature points of the energy storage materials of phase change selected, both cold-storage can be used as, also can be used as accumulation of heat, if this energy storage system is used for accumulation of heat, the transition temperature range of so selected energy storage materials of phase change is usually at 70 DEG C ~ about 90 DEG C; If this energy storage system is used for cold-storage, the transition temperature range of so selected energy storage materials of phase change is usually at 4 DEG C ~ about 7 DEG C; If this energy storage system is used for traditional air conditioner waste heat recovery, the transition temperature range of so selected energy storage materials of phase change is usually at 40 DEG C ~ about 70 DEG C; Usually, this energy storage system can also combine with heat pump the Teat pump boiler becoming the energy storage of a kind of energy; Especially, after combining heating, this energy storage system just can become pure electric energy-accumulated water heater, and the paddy electricity making full use of evening carrys out accumulation of heat, and daytime just can realize round-the-clock central hot water supply without kilowatt-hour; The heat storage water tank of solar energy can also be become.The topmost technological highlights of the present invention is: 1, thoroughly solve heat transfer problem and the problem of phase separation of energy storage materials of phase change, by energy-accumulation material being filled in diameter in the bellows interior of about 30mm to 50mm and bellows dish in layer in inner bag, be equivalent to energy storage materials of phase change all in being horizontally disposed with and the not super 50mm of the thickness of every layer, tightly wrapped by bellows tube wall, the area of dissipation on its surface is even and large simultaneously; 2, thoroughly solve the expansion issues of energy storage materials of phase change, by the inner bag of this energy storage system is separated into two inner chambers, i.e. the first inner chamber and the second inner chamber, first inner chamber integrated in funnel-form and and the inner space of bellows be integrally formed the container cavity that can be held energy storage materials of phase change, this container cavity top is provided with perfusing hole and exhaust outlet, perfusing hole is convenient to the perfusion of energy storage materials of phase change, exhaust outlet then remains that the pressure in container cavity is normal pressure, reserve corresponding expansion space in container cavity simultaneously, overflowed because of expansion to prevent energy storage materials of phase change; 3, because the tube wall of bellows corrugated ringwise, even if adjacent bellows close-packed arrays, space is each other connected, become a good fluid thermal interchange channel, one end of this passage is fluid inlet, and the other end is fluid issuing, the total body surface area of whole bellows is quite large, is beneficial to very much the timely exchange of heat.

For achieving the above object, the utility model have employed following technical proposal: a kind of energy storage system, is characterized in that: comprise housing, and this housing is provided with fluid inlet and fluid issuing; Inner bag, this inner bag is arranged in described housing, and the inwall of described fluid inlet and fluid issuing and this inner bag is through;
