Description
What the present invention relates to is a kind of open-type compression refrigerating apparatus, and this device is applicable to air-conditioning and ventilation.
At present, the refrigerating plant of air-conditioning, ventilation usefulness adopts vapor-compression refrigerant cycle more.This refrigerating plant is made up of vapour compression machine, condenser, choke valve, evaporimeter and connecting line, and its refrigeration working medium is not Lyons or ammonia.Not there is destruction in Lyons to atmospheric ozone layer, and ammonia has excitant peculiar smell, explosive.Therefore, seek a functional and free of contamination alternative refrigerants and become one big problem in the present age.Review history, a long time ago people once to study with the air be the compression refrigeration circulation of working medium, the refrigerating plant of its form is by a compressor that is used to compress working medium, heat exchanger that is used for cooling working medium and one be used to expand working medium and reclaim the decompressor three big critical pieces compositions of merit.The open type refrigerating plant of taking back thermic devices is to have added a backheat heat exchanger on above-mentioned refrigerating plant basis.Compressor in the existing refrigerating plant and decompressor generally all adopt piston type or variable displacement type.Have the people once to do on this basis a little and improve the seventies, and the mixture that promptly adopts empty G﹠W is as refrigeration working medium, and compressor and decompressor adopt the variable displacement type compression-expander as one.Though its performance has improvement slightly, but do not overcome itself two big fundamental drawback: the unit volume compressor refrigerating capacity is little and the coefficient of performance is low.Its reason one is that air specific volume is big, and the compression device that needs is big, the 2nd, and the efficient of compressor and decompressor is low.Therefore, seldom be used.
The objective of the invention is to provide a kind of open type air-conditioning, ventilate and use refrigerating plant, to solve the deficiency of prior art.
The object of the present invention is achieved like this: utilize existing axial-flow turbine compressor and axial-flow turbine turbine respectively as have, the compressor and the decompressor of two kinds of open-type compression refrigerating apparatus of no regenerative apparatus, adopt air-water vapour as refrigeration working medium simultaneously.Like this, just formed one by the axial-flow turbine compressor, form air-water vapour compression refrigerating apparatus that heat exchanger and axial-flow turbine turbine three big critical pieces are formed and one are by the axial-flow turbine compressor, heat exchanger, open type air-water vapour compression refrigerating apparatus of taking back thermic devices that backheat heat exchanger and axial-flow turbine turbine four big critical pieces are formed.Open type air-water vapour compression refrigerating apparatus is work like this: utilize the axial-flow turbine compressor that the humid air that has tiny water smoke is compressed, thereafter with cold water the Moist Air at High Temperature and Pressure stream that obtains is cooled off, make part water recovery Cheng Shui, again the high pressure humid air that obtains is sent into and expanded in the axial-flow turbine turbine and the recovery section merit, make it become the low temperature saturated air, the low temperature humid air that obtains just can or ventilate for air-conditioning by dehydration and use.
Take back the open type air-water vapour compression refrigerating apparatus of thermic devices, just on axial flow air-water vapour compression refrigerating apparatus basis, between heat exchanger and axial-flow turbine turbine, add a backheat heat exchanger.Utilize this backheat heat exchanger that the humid air that cooled off in the heat exchanger is in front further cooled off, make more water recovery Cheng Shui, enter again and expand in the axial-flow turbine turbine and the recovery section merit, make it become the low temperature saturated air.The low temperature humid air that obtains by dehydration, enter backheat heat exchanger cold airflow channel entrance, after heat absorption, then obtain the humid air that temperature is not high, water capacity is lower in backheat heat exchanger cold airflow channel outlet, this humid air just can or ventilate for air-conditioning and use.
The present invention's advantage compared with prior art is: this refrigerating plant is a refrigeration working medium with the mixture of empty G﹠W, based on existing axial-flow turbine machinery.Because the efficient height of axial-flow turbine machinery, the characteristics that flow is big, so characteristics such as that this refrigerating method and device have is nontoxic, pollution-free, do not burn, volume is little, refrigerating capacity is big, coefficient of refrigerating performance is high, cost is low.The present invention is specially adapted to big-and-middle-sized air-conditioning, the ventilation of damp-heat area.
