Description
One, technical field
The present invention relates to a kind of refrigeration air-conditioner, specifically a kind of air condition system of heat pipe storing energy.
Two, background technology
Since reform and opening-up, the overall national strength and the living standards of the people of China all are greatly increased.Though the power industry of China has obtained tremendous development, but the needs of fast development of national economy and people's lives electricity consumption sharp increase are not still satisfied in the growth of electric power, and national short of electricity situation still exists.At present, power supply shortage mainly shows following aspect:
(1) the network load rate is low, and system's peak-valley difference strengthens, and the peak power wretched insufficiency causes the frequent power cuts to limit consumption of electrical network.Peak-valley difference accounts for the ratio of peak load up to more than 30%.
(2) urban electric power consumption increases rapidly, and urban distribution network can not adapt to, and causes the situation of electricity under can not sending, join not.Controller switching equipment overload operation situation all appears in summer high temperature weather, many cities.
The peak-valley difference of electrical network is big characteristics of modern power network, and the trend of aggravation is arranged along with economic development.Along with the continuous development of Chinese national economy, build power plant though department of State Grid consumes a large amount of financial resource and material resource, but still do not satisfy the needs that annual power consumption increases with 5%-7%.Particularly in recent years along with the continuous development of urbanization process, the urban architecture energy consumption presents the trend of accelerated growth.According to statistics, air conditioning electricity has just accounted for more than 30% in the power consumption of the metropolitan peak of domestic part, makes the power system peak-valley difference sharply increase like this, and the network load rate obviously descends, and this has greatly influenced the cost of generating and the safe operation of electrical network.
Energy-storage air conditioner system can transfer electrical power peak power consumption, balance electrical network peak-valley difference, therefore can reduce the new power plant construction investment, improve the utilization rate of existing generating equipment and power transmission and transforming equipment, simultaneously, can reduce the environmental pollution that the energy uses (particularly for thermal power generation) to cause, make full use of limited non-renewable resources, help the ecological balance.According to relevant department's measuring and calculating, if China's network load rate improves one percentage point, then can annually save 7,000,000 tons of mark coals, can reduce SO
2About 400,000 tons of discharge capacity reduces CO
21,200 ten thousand tons of discharge capacitys.
Because electric energy itself is difficult for storing, therefore aspect electricity consumption, consider way usually.Air conditioning electricity is in electrical network, and the ratio in the particularly civilian electricity is increasing.According to statistics, general office building air conditioning electricity accounts for more than 1/3, and air conditioning electricity accounts for 50%-60% in the building of market, and the power consumption of domestic air conditioning year is equivalent to 50% of the three gorges hydropower plant capacity more than 40,000,000,000 kilowatt hours.Starting with from air conditioning electricity, to solve electrical network peak-valley difference problem the most effective beyond doubt, and the energy accumulation air conditioner application is very extensive, is mainly used in following field: the air-conditioning system of commercial building, hotel, restaurant, bank, office block; Domestic air conditioning; Gymnasium, cinema air-conditioning system etc.
For encouraging user's peak load shifting, power department has been formulated the time-of-use tariffs policy together with the place, peak electricity tariff and low ebb electricity price are drawn back, make the 1/3-1/5 of the only suitable peak electricity tariff of low ebb electricity price, encourage the user to use low ebb, this policy is implemented in some areas at present, and will extend to the whole nation.
Under the situation of power supply shortage, because the enforcement of time-of-use tariffs policy, for the energy accumulation air conditioner technology provides vast potential for future development.
At present on the domestic and international market, rarely found have an air-conditioning system that can satisfy refrigeration (heat), cold-storage (heat), cooling (heat) simultaneously.For air condition system of heat pipe storing energy, still blank at home, it will have broad application prospects.
Three, summary of the invention
In order to overcome the deficiency of existing air-conditioning system, the object of the present invention is to provide a kind of air condition system of heat pipe storing energy.Different and common cold-storage or the systems for air conditioning of this system, it will hold (confession) cold, hold (confession) thermal cycle and refrigeration, heat the circulation be coupled, cold or heat by cold-producing medium by indoor units to indoor cooling or heat supply, really accomplished refrigeration, cold-storage, cooling and heat, accumulation of heat, heat supply be integrated.
