Description
Technical field
The present invention relates to a kind of central air conditioner system, particularly a kind of latent heat type central air conditioner system of utilizing hydrate slurry as refrigerating medium.
Background technology
Existing various big-and-middle-sized central air conditioner system nearly all with the chilled water of liquid state as the storage and the conveying of carrying cold media implementation cold, promptly so-called cold water formula central air-conditioning.In this cold water formula central air conditioner system, cold water obtains cold in the refrigeration unit evaporimeter after, temperature reduces (generally dropping to 7 ℃), be transported in each air conditioning terminal heat transmission equipment (as fan coil etc.) by water pump and insulated piping again and discharge cold, temperature rising (generally rising to 12 ℃), sent back to the evaporimeter of refrigeration unit then again, finished a circulation.Therefore, in big-and-middle-sized central air conditioner system, transmission nearly all circulates by cold water and finishes from refrigeration unit to the cold each terminal heat transmission equipment.Though that cold water has is nontoxic, corrosivity is little, stable in properties, plurality of advantages such as cheap, but carry (promptly not having phase transformation takes place) because cold water carries the mode of cold to belong to sensible heat, its cold carries density (refrigerating medium that is exactly specific discharge utilizes following the cold that can carry of the temperature difference in unit) very low.So the cold that the unit volume fluid can be stored or carry is very limited.For the very high big-and-middle-sized central air conditioner system of various cold water formulas of cold delivery requirements, the flow of required refrigerating medium (cold water) is also very big, and this not only needs thick line size, and the delivery pump merit that is consumed also can be very high.For common central air conditioner system, keep the pump merit that cold water circulation consumed and in the comprehensive energy consumption of whole air-conditioning system, can reach 30% ratio.On the other hand, the transmission of sensible heat heat needs the bigger temperature difference, this problem with regard to having caused the heat-exchange system efficiency to descend.
Compare with sensible heat heat transfer, follow the latent heat of phase-state change to conduct heat then to have the cold transmission density is big, heat transfer temperature difference is little advantages such as (even can realize the constant temperature heat exchange).Up to the present, all there be many application ice is starched to carry out the research report that cold is carried both at home and abroad.These research and propose application ice slurry, and---being the mixed muddy suspension body of solid-liquid two-phase that solid ice pellets and aqueous water form under 0 ℃ by a certain percentage---carries as the high density cold in the refrigerating medium realization central air-conditioning.Because the ice slurry contains solid-state ice, so it can carry cold by the crossing latent heat of ice.The crossing latent heat of ice is 80kcal/kg, and is bigger 80 times than the sensible heat (1kcal/kg) of water under 1 ℃ of temperature difference, and therefore the ice slurry utilizes the cold under the temperature to carry density far above cold water identical.On the other hand, because the ice slurry is a kind of muddy suspension body that contains aqueous water, be a kind of fluid with good fluidity, therefore can carry with pump and pipeline easily as common cold water.If can starch refrigerating medium---the cold water that replaces in the existing central air-conditioning with ice, then the cold of refrigerating medium carries density to be greatly improved, this just means that the circular flow of refrigerating medium in pipes system can reduce significantly, therefore the energy consumption of keeping the refrigerating medium circulation also will significantly reduce thereupon, simultaneously the circulating line downsizing be can also make, material cost and space saved.This shows, utilize the solid-liquid two-phase of ice slurry or other similar ice slurry to mix the refrigerating medium that slurry is carried as cold, will bring huge energy-saving benefit for various central air conditioner systems.
Though the application prospect of ice slurry high density latent heat conveying technology in central air conditioner system is considerable, also is faced with many intrinsic defectives and a technical difficult problem.At first, the generation temperature of ice slurry is on the low side (being below 0 ℃, by the freezing point decision of water).In order to produce out the ice slurry, the evaporating temperature of refrigeration machine must drop to below-5 ℃ usually, low like this evaporating temperature makes that the Energy Efficiency Ratio (COP) of refrigeration system is very low, can only reach about 60% of common handpiece Water Chilling Units usually, has increased the energy resource consumption of refrigeration compressor significantly; Secondly, solid ice particles and the density difference between the aqueous water in the ice slurry are bigger, occur the frozen water lamination in course of conveying easily, and this distribution to the conveying of ice slurry and cold is all unfavorable; The 3rd, between ice pellets and the ice pellets once contacting, very easily be incorporated into bigger particle, therefore the ice slurry is easy to harden and blocking pipe equipment with regard to ice cube occurring in pipe conveying procedure, and this also is to restrict ice slurry high density latent heat conveying technology at present to move towards one of practical major obstacle.
Based on above technical background, the present invention proposes the refrigerating medium carried as cold with a kind of hydrate slurry of ammonium salt, replace refrigerating medium---the cold water in the existing cold water formula central air conditioner system, thereby make central air conditioner system realize the energy-saving benefit of cutting down significantly by the refrigerating medium circulation power consumption that the high density latent heat conveying technology brings
