In existing refrigerating plant, develop the most perfectly with traditional enclosed freon vapor compression refrigeration system, use the most generally.But this type of refrigerating plant energy consumption is higher, and generally all is applied to period peak times of power consumption that electricity consumption is relatively concentrated, thereby has caused the problem of shortage of electric power in a period of time easily, and then has aggravated the contradiction of power supply peak valley.One side is along with living standards of the people improves constantly, and refrigerating plants such as domestic air conditioning refrigerator have begun the more and more general huge numbers of families that enter, and on the other hand, the continuous development of industry and other industry level also proposes increasing requirement to refrigeration industry.This problem and contradiction show outstanding day by day, need solution badly.
In order to overcome the above problems, the various countries scholar launches research one after another, has found some solutions, as adopting cold-storage technology such as ice cold-storage, water cold-storage, eutectic salt cold-storage with the reasonable peak load shifting of electric power resource, alleviate electricity consumption contradiction to a certain extent, reduced electrical network pressure.
Above-mentioned these solutions have remedied the deficiency of traditional freon vapor compression refrigeration system to a certain extent, but still have many problems.With the ice cold-storage is the energy accumulating technique inefficiency of representative, and system's bulky complex, and initial cost is bigger, has also increased management difficulty, has limited it and has promoted on a large scale.
Summary of the invention
The objective of the invention is to avoid the weak point of above-mentioned technology, and a kind of air compressor with energy storage and refrigeration function is provided.
Blower outlet successively with cooler, device for drying and filtering, first stop valve, high-pressure bottle, second stop valve, heat control valve, heat exchanger and decompressor link to each other, another gases at high pressure outlet of automatic water trap import and cooler links to each other, heat exchanger, decompressor and blower fan place first backwind tube, outlet of first backwind tube and decompressor outlet link to each other with the first discharge pipe import, decompressor links to each other by the refrigeration compressor of mechanical transmission mechanism with the compression-type refrigeration device, the air ports of the evaporimeter of compression-type refrigeration device links to each other with the outlet of second backwind tube and the second discharge pipe import respectively, the outlet of the one the second discharge pipes links to each other with total discharge pipe import, the signal input part of control and regulation equipment links to each other with the temperature element of total discharge pipe, and its signal output part links to each other with heat control valve and blower fan respectively.
Accumulation of energy of the present invention and refrigeration can be established one's own system, and independent operating is realized striding the time, strides the space accumulation of energy.Promptly both can be in same local low power consumption phase accumulation of energy, peak times of power consumption freeze, and realize the effect of the peak load shifting on the period; Also can realize the functions of accumulation of energy and refrigeration respectively, thereby realize the space transfer of energy in different places.If by utilizing other driven by energy compressor compressed air such as wind-force, waterpower or nuclear power, utilize expansion work to drive wasted work elements such as refrigeration compressor and blower fan simultaneously and can realize zero power consumption accumulation of energy, refrigeration respectively, can use at have a power failure period or areas without electricity.When cooler adopts water-cooled, can produce the higher domestic water of temperature, thereby realize cold-heat combined.
The present invention adopts the compression-type refrigeration device to reclaim the merit that decompressor does to be used for obtaining more refrigerating capacitys, and this method is simple and reliable, and efficient is higher.Before decompressor, be provided with heat exchanger, and it is placed the return air pipeline together with decompressor, carry out heat exchange, directly increased refrigerating capacity on the one hand, also improved the output work of decompressor on the other hand by return air and they.The pure air of the process purified treatment of air side finally directly enters uses cold place, and not only heat exchange effect is remarkable, and energy loss is little, and can effectively improve the air quality with cold place.
The present invention is simple in structure flexibly, and control is convenient, can reach the cryogenic temperature of 20 ℃～-80 ℃ of warm areas by suitable adjusting, also can satisfy multi-user's requirement by a plurality of total air outlets are set, and divide family control simple.Can select high-pressure bottle is placed underground according to actual conditions, promptly increase safety coefficient, reduce it again and taken up space.
