Abstract
The present invention relates to an energy saving refrigerating agent for a compression refrigerator, which is prepared from propane, butane and carbon dioxide. Compared with a freon R12 refrigerating agent widely used at present, the refrigerating agent of the present invention has the advantages of large vaporization latent heat, strong refrigerating capacity, low boiling point, low refrigerating temperature, low molecular weight, low viscosity, easy flow, low price, easy obtainment and no damage to the atmospheric ozone layer and is a refrigerating agent worth of wide generalization.
Description
The present invention relates to a kind of refrigeration agent that is used for compression refigerating machine.Obtain low temperature and be called refrigeration.Refrigeration modes has compression, and is absorption, the electromagnetic oscillation formula, and semiconductor-type and solar energy type are multiple.What use was maximum at present is compression and absorption, uses the most extensive with compression especially.
Compression refigerating machine is made of the refrigeration system of a sealing compressor, condenser, kapillary, vaporizer, the lower boiling refrigeration agent of perfusion in refrigeration system, compressor relies on the power of electric motor to order about refrigeration agent reciprocation cycle in refrigeration system, promptly liquefied by the condenser radiating and cooling by the high temperature and high pressure gaseous refrigerant after the compressor compression, high pressure liquid refrigerant is by capillary-compensated step-down inflow evaporator, in vaporizer, liquid refrigerant is vaporized rapidly and is absorbed extraneous heat acquisition low temperature.The low-temp low-pressure gaseous refrigerant is sucked compression again, so circulation by compressor.
As seen, the latent heat of vaporization of refrigeration agent (heat that absorbs from the external world during 1kg refrigerants vaporize) and two physical parameters of normal boiling point (boiling point under 1atm pressure), be to select the epochmaking technical indicator of refrigeration agent: the latent heat of vaporization of refrigeration agent is bigger, refrigerating capacity is just bigger, and the merit that compressor consumes is just little; The normal boiling point of refrigeration agent is lower, and refrigeration temperature is just lower.
The refrigeration agent kind is a lot: (1), mineral compound class refrigeration agent such as WH

2) make the refrigeration agent of family expenses compression refigerating machine (refrigerator, conditioner), R
12Has the low (R of refrigeration temperature
12Normal boiling point-29.8 ℃), do not fire, not quick-fried, nontoxic, chemical is comparatively stable, corroding metal advantage not, but R
12The latent heat of vaporization very little (39.7 kilocalories/kilogram), refrigerating capacity is low, current consumption is big; R
12Molecular weight big (120.9), viscosity is big, is difficult for flowing, current consumption is big; Especially R
12Atmospheric ozone layer is had destruction, this problem, the whole world is extremely paid close attention to, and cry is very high.
The invention provides a kind of refrigeration agent.It is by propane, molar fraction 0.1～0.5; Butane, molar fraction 0.1～0.7; Carbonic acid gas, molar fraction 0.15～0.8; The denier propylene, butylene, methane, ethane is defended alkane, hydrogen sulfide, the low-boiling composite of composition.
With freonll-11 R
12Compare, the present invention has following advantage:
1, atmospheric ozone layer there is not destruction;
2, R

12Very large many, be a kind of economized refrigerant,
4, R
12Molecular weight be 120.9, the molecular weight of each component among the present invention is all than R
12Little, its adduction molecular weight is also than R
12Little, viscosity of the present invention is little, easily flows, and saves electric power;
5, R
126 yuan/kg of price, the about 3.5 yuan/Kg of price of the present invention.
