Description
Technical field
The present invention relates to a kind of chilling air conditioning system, particularly a kind of high temperature ice ball type cold storing air-conditioning system of utilizing hydrate as cool storage medium.
Background technology
Along with the increase year by year of various air conditioner users, the power consumption of air-conditioning unit occupies increasing proportion in electrical network, brings very big pressure to supply of electric power.In the peak period that summer air-conditioning uses, just in time be the rush hour of network load when need use air-conditioning daytime particularly, supply falls short of demand for electric power.And when night network load at a low ebb, when supply of electric power was had more than needed, air-conditioning but mostly was in closed condition.So there be serious conflicting in the power consumption of air-conditioning and the peak load of electrical network between distributing.Especially under the present situation of present China power shortages, how the reasonable use energy has become one of the most urgent current problem.In order to alleviate supply of electric power burden, reach the purpose in electrical network peak clipping Pinggu, encourage daytime power load transfer to the corresponding appearance of various policies at night.Such as carrying out the peak valley different pricing of electric power, night, electricity price was lower than daytime significantly; Whenever the peak valley electric load of finishing certain unit shifts, and Utilities Electric Co. or government will give certain award or the like.In this case, cool storage air conditioning technology is arisen at the historic moment.
The basic principle of cold accumulation air-conditioner is exactly to utilize night valley power more than needed to start refrigeration machine, cold is stored by cool storage medium, to daytime again released cold quantity for the air-conditioning use, to avoid or to reduce peak of power consumption electrification in period by day.Cold accumulation air-conditioner can be divided into phase change cold-storage and two kinds of forms of non-phase change cold-storage according to the difference of cold-storage mode, and the former is as various ice cold-storages, hydrate cold-storage etc., the latter such as water cold-storage etc.Because with the water cold-storage is that the non-phase change cold-storage of representative is to utilize the sensible heat of cool storage medium to store cold, so storage density of cold is little, it is big to take up an area of the space, and this cold-storage mode is eliminated gradually.With the ice cold-storage is that the phase change cold-storage of representative then is to utilize the latent heat of phase change of cool storage medium to come cold-storage, so storage density of cold is big, and it is little to take up an area of the space.So the ice cold-storage has become the first-selection of present cold accumulation air-conditioner.
The ice cold-storage can be divided into various ways such as coiled, ice ball type and dynamic ice cold-storage according to the concrete form of ice making and ice-melt is different.Wherein coiled and ice ball type all are that technology is the most ripe, most widely used ice cold-storage mode.Coiled belongs to open system, and ice ball type then is a kind of packaged system, and the two respectively has its different characteristics.Dynamic ice cold-storage is a kind of emerging technology, but up to the present also is not very ripe.
Though the ice-storage air-conditioning that with water is cool storage medium can effectively be network load peak clipping Pinggu, alleviate the electrical network pressure in peak of power consumption period on daytime, ice-storage air-conditioning also has its inevitable defective.As everyone knows, the freezing point of water is 0 ℃, no matter the ice-storage air-conditioning of which kind of form, the evaporating temperature of refrigeration unit all must be lower than 0 ℃ when the ice making cold-storage, otherwise ice can not form.According to the law of thermodynamics, under the identical situation of other condition, the Energy Efficiency Ratio (COP) of the low more then kind of refrigeration cycle of the evaporating temperature of refrigeration unit is also low more, that is to say that the electric energy that is consumed under the situation of making identical cold is also many more.Therefore, the low evaporating temperature of ice-storage air-conditioning causes its Energy Efficiency Ratio (COP) very low, approximately only be equivalent to common non-cold-storage water-cooled handpiece Water Chilling Units (the refrigeration evaporator temperature can reach more than 4 ℃) 60%, under the situation that satisfies identical refrigeration duty demand, the comprehensive energy consumption of ice-storage air-conditioning is than common handpiece Water Chilling Units height at least 30%.
The shortcoming that ice-storage air-conditioning COP is low, energy consumption is high mainly causes by the refrigeration evaporator temperature is low excessively.If can raise the refrigeration evaporator temperature, then this defective will be overcome.Based on above analysis, the present invention proposes a kind of hydrate high temp ice ball type cold storing air-conditioning system.The hydrate ice hockey that this chilling air conditioning system is higher than ice with a kind of phase transition temperature replaces the common ice hockey in the ice ball type cold storing air-conditioning, the refrigeration evaporator temperature is greatly improved, thereby both inherited the major function in common ice ball type cold accumulation air-conditioner peak clipping Pinggu, improved its shortcoming that cold-storage Energy Efficiency Ratio is low, energy consumption is big again.
Summary of the invention
The objective of the invention is for a kind of ice ball type cold storing air-conditioning system is provided, this air-conditioning system adopt the hydrate high temp ice hockey but not common cold-storage ice hockey as cool storage medium, the phase transition temperature of this hydrate high temp ice hockey is far above ice, when cold-storage moves the Energy Efficiency Ratio (COP) of refrigeration machine is greatly improved at night, thereby makes this hydrate high temp ice ball type cold storing air-conditioning realize tangible energy-saving benefit.
