Description

The ice slurry cold storage central air conditioner system
Technical field
The invention belongs to central air conditioner system, specifically is a kind ofly to shift the load energy-conserving and environment-protective central air conditioner system of night dip electric load of peak power on daytime with ice slurry as the energy storage carrier.
Background technology
In recent years, although China's electric power industry development is very fast, but it is still very nervous in some developed area electricity consumptions, the bottleneck, particularly summer air-conditioning power consumption that become the restriction local economic development have generally surpassed 1/3rd of electric power total load, a few cities even near 50%, what form sharp contrast with it is electrical network about night, volatile quantity can be up to 50%, in time unbalanced of electricity needs is to cause the very important reason of power tense, and main cause is again on air-conditioning so.Simultaneously, the quick growth of urban life, commercial electricity consumption, particularly summer the increasing suddenly of power load, make urban distribution network far can not adapt to.Therefore, " saving peak power " become government and electric administrative department is devoted to one of important and long-range measure of alleviating power shortages, and by the realization of economic means such as formulation electricity consumption preferential policy with promotion electric power " peak load shifting ".
We can say that the cold-storage technology is exactly to adapt to this needs and a new and high technology that is applied to air conditioner energy saving being born, utilize unnecessary electricity, the low-price electricity cold-storage at night, to ice-melt during peak of power consumption on daytime, stored cold is discharged, alleviate peak electricity consumption pressure, satisfy building cooling demand, realize that daytime, air-conditioning used few power consumption or " zero power consumption ".Application result shows, can be the user and saves the electricity charge about 20-30%.For country, reduced to dealing with the input that daytime, peak of power consumption was appended, coal is burnt in few generating less, and few the discharging improved the utilization ratio of electric energy at night again.The penetration and promotion of cold-storage technology can not only greatly promote the adjustment of national electric energy structure, can also reduce a large amount of raw coal wastings of resources for country, can reduce emissions such as a large amount of carbon dioxide, sulfur dioxide again simultaneously.
Based on this, cold accumulation air-conditioner has obtained the approval of society.The building of developed country more than 60% all used cold accumulation air-conditioner at present, China also implemented electricity price peak-valley difference policy in 2004 in the whole country appearance, for example the present cold accumulation air-conditioner valley period power in Shenzhen valency is 0.28 a yuan/kilowatt hour, the time-of-use tariffs ratio has surpassed 4 times, and will constantly widen electricity price between peak and valley, " peak load shifting " technology of support is used and is promoted, and some areas government has put into effect mandatory policy, requires the above newly-increased building of 30,000 square meters must use cold accumulation air-conditioner.
The cold-storage technology is utilized technology as a class important energy, has obtained very great development recently, has the associated companies that many families are engaged in cold-storage on the domestic market at present.
With the excellent company of Beijing Pei Er is the water cold-storage company of representative, the advantage of water cold-storage is to increase and to change original refrigeration system, only need to increase and utilize cold the getting final product of existing fire-fighting cistern storage, newly-built low with improvement cost, but the storage density of cold of water cold-storage lower (be about ice cold-storage 1/6~10), if water cold-storage tank volume is 6~10 times of ice cold-storage tank volume under the identical situation of cold storage capacity, therefore the cold-storage jar is too big, can only have than the place in large space place at some and use, as the airport, use and be subjected to certain limitation.
Eutectic salt cold-storage mainly is that the CIAT company of France is promoting, more domestic mechanisms such as Tsing-Hua University, Chinese Academy of Sciences Guangzhou Energy Research Institute etc. have also developed some phase-change materials, advantage is that system is simple and application is convenient, shortcoming is can progressively decay in phase change material cool storage performance and life-span, there are problems such as the replacing that expires service life, add the more expensive and replacement cost of cost own, so use less at present.
From cold-storage applicable cases both domestic and external, the most general cold-storage of still icing, it accounts for more than 95% of total cold accumulation system quantity, and the existing ice storage air conditioner engineering 99% of China all belongs to static ice-reserving technology at present.
The ice cold-storage is divided into static ice making and dynamic ice-making again according to the ice making mode.Static ice storage air conditioner mainly is with the static mode ice making, promptly freezes outside coil pipe or in the ice filling container (ice hockey, slab), and ice itself is in relative static conditions all the time.It needs coil pipe, ice hockey, slab and a large amount of refrigerating mediums of corresponding cold storage capacity to freeze, and reaching ice making and ice-reserving is one.The dynamic ice-making mode then is that ice making and ice-reserving separately carry out, and makes water generate ice crystal or ice slurry, and ice crystal, ice slurry can be carried with pump.
But there is following shortcoming again in a large amount of at present static ice makings of adopting, because ice itself remains static, growth along with the ice making time, the ice thickness degree will slowly increase, the thermal resistance effect of ice is just more and more obvious, the heat transfer property of ice itself and ice thickness degree are inversely proportional to, and are directed at ice making middle and later periods refrigeration host computer refrigerating efficiency and seriously descend, and directly bring the decline of efficiency of energy utilization.
Static ice storage air conditioner ice making and ice-reserving are one, cold storage capacity is proportional with coil pipe quantity or ice hockey, slab quantity, consequence is that the big more cost of investment of cold storage capacity is also big more, so consider that from cost of investment it is limited shifting peak load, usually be about 20%~30% of the highest total refrigeration duty, but also have problems such as refrigerating medium leakage and coil pipe, ice hockey, slab manufacturing cost height.
Summary of the invention
The present invention seeks to release a kind of ice slurry cold storage central air conditioner system, to solve the deficiency of existing static ice-reserving central air-conditioning based on the dynamic ice-making technology.
The ice slurry cold storage central air conditioner system is refrigeration, heat exchange, ice making, ice storage, with the central air conditioner system that assembly branch such as cold is arranged, and is purpose for improving ice making efficient and reducing system cost.Main heat-exchange system adopts the higher liquid liquid plate heat exchanger of heat exchange efficiency, thoroughly solves static ice making ice sheet thermal resistance and is directed at refrigeration host computer refrigerating efficiency decline problem.Ice making is carried out separately in ice slurry generator after water temperature is reduced to below the zero degrees celsius, and the ice slurry of generation is delivered to ice storage tank by pipeline and stores.Cooling of the present invention send water, cold air distribution that condition is provided for the big temperature difference.Have the advantages that to be in best heat exchange efficiency section in the ice making cycle all the time, also have: no coil pipe, no ice hockey, no slab, ice-melt are fast, load follow is good, ice storage tank is provided with flexibly, ice starch can carry at a distance with pump, advantages such as leaving water temperature is low, effluent temperature constancy.
