Description
Technical field
The present invention relates to a kind of energy storage equipment, particularly relate to a kind of energy storage equipment that is used for air-conditioning, hot water supply.
Background technology
Water resource heat pump has the characteristics of Energy Efficiency Ratio height (COP 〉=5), has obtained developing faster and using at aspects such as air-conditioning, hot water supplies.But owing to be subjected to the restriction of water resource, its promotion and application have been subjected to very big restriction simultaneously again.Therefore in most of the cases, people are in air-conditioning, heating and domestic hot-water's supply, and form still adopts air source heat pump, solar thermal collector more easily.Lower and when having certain humidity when outdoor environment temperature, the just frosting easily of the surface cooler of air source heat pump surface; Efficient is relatively low when heating water, and it is bigger to consume energy, even adopts electric energy directly to heat, and is unfavorable for saving the energy.But air source heat pump has but that the incomparable advantage of other kind heat pumps---energy source is unrestricted when being used for low-temperature heating.The utilization of solar energy had obtained in recent years developing rapidly and had used comparatively widely, mainly concentrated on various ways such as solar water heater, solar energy photovoltaic panel generating, solar boiler generating.But because the discontinuity of its time makes the utilization of solar energy not to be applied to widely in the daily life, as the building heating engineering etc.
Summary of the invention
Above-mentioned defective at existing in the prior art the invention provides a kind of energy storage equipment, and it can store energy efficient is jumbo, to regulate ageing in the energy use.
The present invention is achieved by the following technical solution: a kind of energy storage equipment, comprise casing, and be provided with two groups of capillary heat exchange structures that are used for accumulation of energy and exoergic respectively in the described casing, but be filled with the heat accumulating of phase transformation in the box cavity.
The present invention gives phase change medium by one group of capillary heat exchange structure with heat delivery, and phase change medium absorbs and storage power, and when system needed heat, another group capillary heat exchange structure can extract heat from energy storage equipment, satisfy life or requirement of engineering.Because the phase change medium material when undergoing phase transition, can absorb or discharge lot of energy, therefore can make the accumulation of energy ability of energy storage equipment obtain bigger raising as energy-accumulation material with it.Heat exchange area is big because capillary has, heat exchange is even, good effect of heat exchange, therefore adopts it to can greatly improve heat exchange efficiency as heat exchanger.
Described capillary heat exchange structure comprises two connection pipes that communicate with heat transferring medium confession, return pipe road respectively, is parallel with some capillaries on the connection pipe.In order to meet working condition requirement, the material of capillary heat exchange structure can adopt has hot-melt plastic material high temperature resistant, high pressure resistant, corrosion-resistant characteristic, as PPR, PE-RT or PB etc., and preferred PPR material, not only be green material, and can make energy storage equipment that application is widely arranged.Consider heat exchange efficiency capillaceous and load performance thereof, external diameter capillaceous is generally 5～6mm.
In order to improve heat exchange efficiency, two groups of capillary heat exchange structures of the present invention adopt counter-flow arrangement, and each intercapillary spacing is: 10～15mm, preferred 12mm.This kind counter-flow arrangement mode not only is beneficial to heat exchange, and more phase transformation nuclear is provided simultaneously, makes that to hold (putting) heat more efficient, and the volume of whole energy storage equipment is reduced.
Phase change medium material among the present invention should be selected suitable material according to the phase transition temperature of accumulation of energy requirement, and phase-change material can be inorganic salts or organic matter.When the phase transition temperature that general accumulation of energy requires is low, can adopt inorganic salts as the phase change medium material, it has the accumulation of energy characteristics of low temperature phase change, and the phase transformation temperature points of inorganic salts material can change by filling a prescription, and is cheap, also helps reducing operating cost.
Because phase change medium has corrosivity usually, so the casing of energy storage equipment should adopt corrosion-resistant material to make, and it can adopt corrosion resistant PPR plastic material.
Energy storage equipment of the present invention can be provided with heat-insulation layer according to instructions for use outside casing, can adopt polyurethane heat insulation material foam-in-place insulation between casing and shell at casing peripheral hardware one shell.
The present invention has well compensated the deficiency of various usings energy source such as solar thermal collector, air source heat pump, water resource heat pump, energy is adopted advanced phase transformation and capillary heat transfer technology as requested, store energy efficient is jumbo, to regulate ageing in the energy use.It can unite use with solar thermal collector, air source heat pump, water resource heat pump etc., improve these equipment efficient, expand its application, reduce the volume of existing equipment.
Good effect of the present invention is: its reasonable in design, and heat exchange efficiency height, heat storage capacity are big, and volume is little.Compared with prior art, it has following characteristics: (1) is energy-efficient.The present invention is owing to adopted unique capillary heat exchange structure and inorganic salts phase change technique, its heat exchange efficiency height, phase velocity is fast, and it is efficient to hold (putting) heat, the cop of heat pump (Energy Efficiency Ratio) reaches more than 3.2 at whole heating phase mean value, and the Energy Efficiency Ratio of traditional heat pump has only 1.8 ~ 2.0 in the winter time.Make solar energy utilize scope, timeliness to widen, can realize not having the auxilliary solar water heater of electricity.(2) convenient and reliable.The technology of the present invention can avoid air source heat pump to be subjected to the restriction of environmental condition so that air source heat pump and water resource heat pump are had complementary advantages, and has widened the scope of application of heat pump, reaches energy-efficient purpose.(3) economical and practical.The technology of the present invention can combine with solar thermal collector, air source heat pump, water resource heat pump, improves the efficient of these equipment, makes the investment running cost be suitable for the requirement of space.It also can adapt to energy-intensive present situation now, can solve peak of power consumption electricity charge problem of higher.When non-peak of power consumption, utilize the air source heat pump efficient operation with the low ebb electricity price, adopt this device to store the heat for preparing, when peak of power consumption, the heat that can utilize this device to store efficiently meets the demands, the effect that has good energy-conservation and cut operating costs.(4) environmental protection.Material therefor of the present invention is recyclable material, and corrosion-resistant, does not have power part, without any pollutant, the service life of having improved device greatly.
