Abstract
The utility model relates to a new-energy novel air energy refrigeration device which comprises a Rankine expansion work-doing cycle and a reverse Carnot refrigeration cycle. Work consumed by a compressor is generated by an expander; the cooling capacity is obtained by the indoor side from a heat absorber; and the condensation heat in the Rankine expansion work-doing cycle is transferred to the normal temperature environment by the reverse Carnot refrigeration cycle.

Technical field
The utility model relates to a kind of new forms of energy compression-type refrigeration device, and especially a kind of novel air can refrigerating plant.
Background technology
At present, known compression-type refrigeration device adopts contrary Kano kind of refrigeration cycle flow process usually, mainly comprises compressor, condenser, choke valve, evaporimeter.Its consumption high-grade mechanical energy Compressed Gas swell refrigeration again makes heat flow out to normal temperature environment from cryogenic system.Its characteristic is that the evaporimeter of heat energy from the kind of refrigeration cycle of contrary Kano of indoor normal temperature air gets into system, and the indoor also obtains cold from evaporimeter.Existing compression-type refrigeration device must consume a large amount of high-grade energy.
Summary of the invention
In order to overcome the deficiency that existing compression-type refrigeration device must consume a large amount of high-grade energy; The utility model provides a kind of novel air ability refrigerating plant; This novel air can refrigerating plant comprise a Rankine expand acting EGR and a contrary Kano refrigerating circulatory device, and one of its characteristic is that merit that contrary Kano kind of refrigeration cycle is consumed comes from the Rankine acting circulation of expanding; Two of its characteristic is that the heat dump of heat energy from Rankine expansion acting circulation of indoor normal temperature air gets into system, and the indoor also obtains cold from heat dump; Three of its characteristic is that refrigerating capacity that contrary Kano kind of refrigeration cycle is produced is used for Rankine the expand condensation of back cryogenic gas of acting circulation of expanding.In theory; Not only this novel air can need not to consume the high-grade energy by refrigerating plant; And this novel air can refrigerating plant refrigerating capacity much larger than the refrigerating capacity of contrary Kano kind of refrigeration cycle, the refrigerating capacity that novel air can refrigerating plant equals the refrigerating capacity of contrary Kano kind of refrigeration cycle and the energy sum that compressor consumed of contrary Kano kind of refrigeration cycle; In fact, based on present technical merit, same refrigerating capacity, the high-grade energy consumption of this novel air ability refrigerating plant also can be significantly less than existing compression-type refrigeration device; Along with going deep into and development of science and technology of research, and the combining environmental thermal source or the low-temperature receiver temperature difference, novel air can be practiced thrift more high-grade energy by refrigerating plant, even can not consume the high-grade energy; Reach the purpose that makes this novel air ability refrigerating plant not consume or consume less the high-grade energy like this.
The utility model solves the technical scheme that its technical problem adopted: this novel air can mainly comprise compressor, condenser, choke valve, internal exchanger, working medium pump, heat dump, decompressor etc. by refrigerating plant; It also comprises pipeline, annex and detection and the control device that is connected in the system, and it has two closed cycle systems, and two interior working medium of closed system can be the same or different.This novel air can comprise a Rankine expansion acting circulation and a contrary Kano kind of refrigeration cycle by refrigerating plant.Working medium pump, heat dump, decompressor, internal exchanger are in turn connected to form first closed cycle system Rankine expansion acting circulation, and compressor, condenser, choke valve, internal exchanger are in turn connected to form the contrary Kano of second closed cycle system kind of refrigeration cycle.In Rankine expands the acting EGR, the heat dump that absorbs the normal temperature air heat is arranged.Rankine expands the acting EGR with refrigerating circulatory device is connected through internal exchanger against the Kano.In the first closed circulation working system Rankine expands the acting circulation; Condensation working medium becomes normal temperature high voltage working medium through the heat energy heating liquid refrigerant that working medium pump gets in heat dump absorption normal temperature fluid-air, in the water, and normal temperature high voltage working medium gets into decompressor expansion acting then; Decompressor outlet is the low-temp low-pressure gaseous working medium, the low-temp low-pressure gaseous working medium in internal exchanger with second closed cycle system in heat release condensation after the low temperature liquid working medium heat exchange of choke valve throttling, formed first closed cycle system like this.In the kind of refrigeration cycle of the contrary Kano of second closed cycle system; Liquid refrigerant evaporation after the choke valve throttling gets into internal exchanger to absorb in first closed cycle system condensation heat of the low-temp low-pressure gaseous working medium after decompressor expands again becomes gaseous working medium; Gaseous working medium gets into compressor pressurizes then; Gaseous working medium after the pressurization goes the condenser heat release to be condensed into liquid refrigerant, and the heat transferred normal temperature environment has formed second closed cycle system like this.This novel air can refrigerating plant decompressor main shaft with compressor main shaft between can be connected.This novel air can the refrigerating plant decompressor can be a multiple expansion engine, and the final stage decompressor can be the decompressor of anti-liquid hammer the or alternative with choke valve.For two identical closed cycle systems of working medium, the internal exchanger of this novel air ability refrigerating plant can substitute with gas-liquid separator, improves heat transfer efficiency with simplified apparatus.For the contrary Kano cooling cycle system of High Pressure Difference, the choke valve of this novel air ability refrigerating plant can use the decompressor of anti-the liquid hammer to substitute, to reclaim merit and to improve refrigerating efficiency.The cold that this novel air ability refrigerating plant produces can be widely used in low temperature heat resource power generations such as air energy power-generating, waste heat used heat underground heat, high-power central air-conditioning, air liquefaction separation, natural gas liquefaction, other industrial gasses liquefaction, freezer or the like many purposes.
The beneficial effect of the utility model is that this novel air can not consume or consume less the high-grade energy by refrigerating plant.
