Description
Technical field
The present invention relates to refrigerating field, the closed refrigeration system of the single thermal source of especially a kind of conventional piston.
Background technology
Refrigeration Technique and equipment are widely used at present, but its wasted work is big, for this reason, human consumption mass energy, also environment has been caused severe contamination.If can invent a kind of with environment as high temperature heat source (promptly be cooled cooling target thermal source); And through low-temperature heat source of built-in system structure; And absorb heat from environment as refrigeration heat sink with this low-temperature heat source; In other words, do not need wasted work just can freeze, this will have epoch making significance.
Summary of the invention
Want to utilize environment as high temperature heat source, in refrigeration system, make up a low-temperature heat source, unique method is exactly with gas that comes from environment or the gas that will in environment, absorb heat, carries out adiabatic degree of depth compression or be similar to adiabatic degree of depth compression; The pressure and temperature of compressed gas all increases substantially in degree of depth compression process; In by the gas of degree of depth compression, sneak into liquid (containing critical condition), liquid takes place to conduct heat with gas and is phase-changed into gas, makes the pressure rising, temperature slightly raises or do not raise or descend; Carry out the adiabatic expansion work done then; The amount of expansion working is greater than the power consumption of compression process, so the external outputting power of system, the gas temperature when work done is over drops to the temperature that is lower than before the compression; At least portion gas liquefies, and has so just made up a new low-temperature heat source.If on the surface; This process has been violated thermodynamic (al) law of correlation, but labor can be known and in high temperature and high pressure gas, sneak into liquid when (containing critical condition); Pressure can significantly raise; Gas temperature when the rising of pressure can cause expansion working to be over declines to a great extent, and the essence of this process is to have utilized the exchange of mass transport process and diabatic process, has replaced diabatic process with mass transport process; Thereby realized making up the purpose of low-temperature heat source, this low-temperature heat source can be used as the low-temperature receiver of process of refrigerastion.
In by the gas of degree of depth compression, sneak into product that the amount of liquid (containing critical condition) should satisfy liquid gasification back gas phase total mole number n, temperature T and gas constant R greater than this product before sneaking into liquid.In by the gas of degree of depth compression, sneaking in the liquid process of (containing critical condition), should keep the constant volume state as far as possible.
In order to address the above problem, the technical scheme that the present invention proposes is following:
The closed refrigeration system of the single thermal source of a kind of conventional piston comprises cylinder and piston, and said piston is arranged in the said cylinder; On the cylinder cap of said cylinder, establish air inlet; The place establishes inlet valve at said air inlet, on the cylinder cap of said cylinder, establishes exhaust outlet, establishes exhaust valve in said exhaust ports; Said air inlet and said exhaust outlet are communicated with through advancing to arrange communication passage; Advance to arrange to establish on the communication passage gas working medium absorption refrigeration device said, advance to arrange communication passage and establish gas-liquid separator with the place of connection of said exhaust outlet said, the liquid outlet of said gas-liquid separator is communicated with said cylinder through liquid working substance high pressure send-back system; Said inlet valve, said exhaust valve and said liquid working substance high pressure send-back system are controlled by process control mechanism, realize after gas working medium is compressed by the degree of depth in said cylinder
When temperature and pressure increases substantially; Said liquid working substance high pressure send-back system is transmitted back to liquid working substance in the said cylinder; Said liquid working substance mix with said gas working medium being heated the gasification pressure is further improved, promote said descent of piston work done, the amount of said descent of piston work done greater than said gas working medium by the needed merit of degree of depth compression process; Said piston is to work done outside the system; The temperature of the said gas working medium behind the expansion working is reduced to and is lower than the temperature of said gas working medium before being compressed, the said gas working medium after the cooling when said piston stroking upward in said exhaust valve is discharged into said gas working medium absorption refrigeration device self heat absorption externally refrigeration that heats up, when said descent of piston; In said inlet valve was inhaled into said cylinder, said gas working medium was got into next circulation by degree of depth compression when said piston stroking upward.
On the circulation passage of said liquid working substance, establish liquid working substance absorption refrigeration device.
Said between gas working medium absorption refrigeration device and said air inlet advances to arrange to establish on the communication passage gas working medium heat absorption low-grade heat source heater.
Establish liquid working substance heat absorption low-grade heat source heater on the circulation passage of the said liquid working substance after said liquid working substance absorption refrigeration device.
The pressure of the disclosed conventional piston of the present invention closed refrigeration system of single thermal source when compression stroke is over is more than or equal to 3.5MPa; 4MPa; 4.5MPa; 5MPa; 5.5MPa; 6MPa; 6.5MPa; 7MPa; 7.5MPa; 8MPa; 8.5MPa; 9MPa; 9.5MPa; 10MPa; 10.5MPa; 11MPa; 11.5MPa; 12MPa; 12.5MPa; 13MPa; 13.5MPa; 14MPa; 14.5MPa; 15MPa; 15.5MPa; 16MPa; 16. 5MPa; 17MPa; 17.5MPa; 18MPa; 18.5MPa; 19MPa; 19.5MPa; 20MPa; 25MPa; 30MPa; 35MPa; 40MPa; 45MPa; 50MPa; 55MPa or 60MPa.
Principle of the present invention is with gas degree of depth compression, sneaks into liquid (containing critical condition) after its temperature and pressure is risen significantly, pressure is further improved and the amplification of temperature is less or do not heat up or lower the temperature, and carries out the external work done of adiabatic expansion then.Because the initial pressure of expansion process is to a great extent greater than compression pressure at the end, thus the amount of gas expansion working greater than the power consumption of compression process, for this reason, system is outputting power externally.The temperature of the gas after expansion working is over is lower than the gas temperature in when beginning compression, so quite a lot of low-temperature heat source can utilize the low-temperature receiver of cryogenic gas as process of refrigerastion, compresses the formation closed circulation after the intensification again.Utilizing cryogenic gas to absorb heat from low-grade heat source; Compress again after the heat absorption in the structure that constitutes closed circulation; The heat of low-grade heat source can be absorbed into earlier in the said liquid working substance, compresses after the said gas working medium after utilizing said liquid working substance to the expansion working cooling heats again.In process of refrigerastion, be equivalent to from the low-grade heat source heat absorption, the back of perhaps in said gas working medium absorbs heat back and/or the said liquid working substance absorption refrigeration of said liquid working substance device in said gas working medium absorption refrigeration device, absorbing heat is at draw heat from low-grade heat source.
So-called low-grade heat source refers to seawater, underground heat, tail gas, waste heat of plant and solar thermal collection system etc. all can provide the thermal source of heat to the working medium in the closed refrigeration system of the single thermal source of the disclosed conventional piston of the present invention among the present invention.
