Description
Technical field
The invention belongs to refrigerant art, relate to a kind of mix refrigerant, relate in particular to the environment-protecting mixed refrigerating agent that contains CF3I of a kind of alternative R22.
Background technology
The R22 refrigeration agent has obtained using widely at air-conditioning and other field with its good thermal technology and transmission performance.Yet R22 is a typical C FCs class material, damages the ozone layer and has Greenhouse effect, and " Montreal Agreement book " and " Kyodo Protocol book " limits it respectively.Regulation: for developed country, R22 uses at most to the year two thousand twenty as refrigeration agent.For developing country, R22 allows to use the year two thousand forty at most as refrigeration agent.Under these circumstances, each state has all carried out the research of the alternative work of R22 refrigeration agent.
At present, mainly contain two kinds of technical schemes in the world about substituting of R22 refrigeration agent: a kind of is to be representative with the Northern European countries, it advocates to adopt natural medium thing as an alternative, as pure working medium R290, R1270, R744, R600a, R600, R717 etc., and the mixture of HCs class; Another kind is to be the employing HFCs thing as an alternative of representative with the U.S. and Japan; zeotrope R410A (R32/R125 as United States Union Signal Co.; the quality proportioning is 50/50), the mixture R407C (R32/R125/R134a of E.I.Du Pont Company and I.C.I company; the quality proportioning is 23/25/52); and R32 and R152a etc.; the ODP of these refrigeration agents is 0, well satisfies the requirement of ozonosphere protection, but global warming potential GWP is higher.In addition, R407C is a tertiary non-azeotropic mixed working medium, and its energy efficiency is low relatively, and the evaporative process temperature glide is big, occur the component separation phenomenon in use easily, the slip temperature that refrigeration agent is big will make operating pressure frequent variations in vaporizer and the condenser, refrigeration system instability.R410A is a kind of binary mix refrigerant, and two components do not meet the thermodynamics substitution principle, and should not directly fill jar, and the two is not fully up to expectations as the long-term alternative refrigerant of air-conditioning.Therefore, the high efficient mixed working medium of carrying out environment-friendly energy-saving still shoulders heavy responsibilities.
With HCs and 1, the mix refrigerant that the 1-C2H4F2 C2H4F2 is formed or HCs forms has stronger thermal technology and transmission performance, has the favorable environment protection energy simultaneously.The for example R432A (R1270/R152A, quality proportioning 80/20) that announces in the recent period of ASHRAE and R433A (R290/R1270, quality proportioning 70/30) etc.Wherein the COP of R432A is 1.085 times of R22, and GWP is lower than 5, and its slip temperature is also very little; The COP of R433A is higher by 4.9～7.6% than R22, and GWP is lower than 5, and its slip temperature is also very little.But HCs, R152a class material all have certain combustibility, and the safety performance aspect do not consider fully, and add the raising security that the flame retardant resistance refrigeration agent can system.
Summary of the invention
The object of the present invention is to provide a kind of environmental protection, safety, reliable, refrigerating efficiency is high, can directly fill the environment-protecting mixed refrigerating agent that contains CF3I of refrigeration equipment such as ullage accent.
In order to achieve the above object, the technical solution used in the present invention is: by 1,1-C2H4F2 C2H4F2 (R152a), propylene (R1270) and CF3I (R13I1) are formed, and the basic parameter of each constituent element material sees Table 1.
