Description
Technical field
The utility model belongs to power peak regulation and thermal energy storage technical field, relates to a kind of air-conditioning phase-changing energy-storing device that is used for the ecotecture power peak regulation,
Background technology
Energy storage is meant for the moment, the energy on a ground stores with certain form, be used for satisfying At All Other Times and (or) energy requirement in place, for the utilization of eliminating inharmonic contradiction between energy supply and demand, improving energy use efficiency and regenerative resource significant values is arranged all.According to the energy storage temperature, the heat energy storage technology can be divided into low temperature energy storage and high temperature energy-storage.According to energy storage mechanism, also it can be divided into sensible heat energy storage and hidden heat energy storage.Compare advantages such as hidden heat energy storage has energy storage density height (high more than the order of magnitude), energy storage-release can temperature stabilization, volume is little, easy control with the sensible heat energy storage.Phase change material is the functive of latent heat of phase change energy storage, and U.S. Dow chemical company once carried out technical economic analysis to more than 20000 kinds of phase change materials, thinks wherein that kind has to utilize surplus in the of 200 to be worth, and phase transition temperature has contained below 0 ℃ to 1000 ℃.At low temperature range (0 ℃-100 ℃), available phase change material is a lot, as organic phase changing matters such as paraffin (paraffins mixture), aliphatic acid and derivative thereof and inorganic hydrous salt phase transition material etc., especially organic phase changing matter have phase transition process stablize reversible, phase transition temperature can be regulated arbitrarily, latent heat of phase change is big, raw material wide material sources, advantage such as cheap, for the exploitation of low temperature phase change hidden heat energy storage technology provides assurance.
One of focus of phase change energy storage technology is to use in ecotecture at present.Comprise and adopt the compound technology of preparing of material that phase change material and encapsulation or framework material are combined with each other, make composite, for example German BASF AG and the cooperation of Fraunhofer solar energy system research institute adopt microcapsules technology that phase change material is encapsulated in the high molecular polymer, be prepared into the phase-change accumulation energy plaster, be convenient to use at building field.The advantage of this method is a phase change material storage reliability height, the energy storage good endurance, but cost is higher.What also have is directly compound with phase change material and building product, make building structure have the dual-use function of load-bearing and phase-change accumulation energy simultaneously, people such as for example Canadian Concordia professor Feldman of university infiltrate building product (as plasterboard or porous concrete building blocks etc.) with organic phase changing matter, make building wall board with latent heat of phase change energy-storage function and building block etc.The advantage of this method is that cost is lower, but also exists phase change material in use to leak easily at present, problems such as storage reliability.
In recent years, season, the electric power peak-valley difference became increasing in full summer, and a large amount of the popularizing of air-conditioning is its one of the main reasons.High-temperature time in full summer, air-conditioning often some period in one day concentrate and start, cause electrical network can't bear the heavy load.And in the relatively nice and cool period, air conditioner load obviously reduces.Excessive peak-valley difference not only can cause huge energy waste, especially causes electric power the problem that supply falls short of demand to occur in some period.Therefore, be badly in need of exploitation and promote feasible power peak regulation means, reduce the electric power peak-valley difference as far as possible, alleviate the situation of electricity supply and demand anxiety.Phase-change accumulation energy is a feasible user side power peak regulation method.Store the cold of air-conditioning by suitable phase-change accumulation energy device, export to the interior space peak period, can effectively alleviate the electric power peak valley phenomenon at electric power in the output of electric power low-valley interval.

The principle of the phase-changing energy-storing peak regulation of the utility model device is as follows: summer, open the refrigerating function of air-conditioner 3 at electric power low-valley interval (generally go up morning every day 0:00 to 8:00), open simultaneously to be positioned at and change wind blower fan 4 near the air-conditioning, directly import the cold of air-conditioner 3 output on the ceiling phase-transformation energy-storage tank 2, to phase-transformation energy-storage tank 2 cold-storages.The temperature of the thermocouple measurement energy storage tank in the energy storage tank 2, and temperature signal reached temperature controller 1, judge by controller 1 whether the phase-change material in the energy storage tank undergoes phase transition fully, fully cold-storage.After the phase-change material phase transformation in the energy storage tank fully, stop the running of air-conditioner 3 and blower fan 4.In electricity needs peak period (general 8:00 by day is to 17:00), the period in the needs refrigeration, need not start air conditioner refrigerating, only start blower fan, utilize the air circulation heat exchange, the cold that stores in energy storage tank 2 is discharged into the interior space gradually.Can adjust compressor flow according to required temperature and load.As a same reason,, utilize the heating function of air-conditioner and the heat accumulation function of phase-transformation energy-storage tank, reach power peak regulation and save the purpose that the electricity charge are paid in winter.
Promote the use of and the utlity model has following benefit:
(1) can contribute to power peak regulation at user side.The concentrated use of building air conditioning become summer and winter electric power peak-valley difference and one of the major reason of power supply shortage.The utility model is the use pattern by changing building air conditioning-disperse to use by concentrating to use to transfer to just, and the air-conditioning electric load during with the peak alleviates the power supply shortage situation when transferring to paddy, reduces peak-valley difference.
(2) can be the user and save electricity charge spending.Tou power price is all implemented in most of cities in China.In Shanghai, electricity price is 0.232 a yuan/degree during paddy of non-industrial operation electricity consumption in summer (being the office building electricity consumption), and electricity price is 1.044 a yuan/degree during peak, and every degree electricity differs nearly 0.8 yuan.Therefore, if can large tracts of land use the utility model to implement power peak regulation, for very obvious with the benefit of saving electricity charge spending.
(3) compare with existing Technology of Cold Storage Air Conditions-ice storage technology, the energy storage equipment temperature that the utility model proposes is higher, can utilize directly that original air-conditioning system embeds in the building, not only has high system effectiveness (COP), but also the dual-use function of tool cold-storage in summer and accumulation of heat in winter, has less investment, the advantage of instant effect.
