In order to compare the effects of the embodiments and the comparative examples, the design conditions of the refrigeration system selected are as follows: the evaporator evaporation temperature (the arithmetic mean of the evaporator inlet temperature and the dew point temperature under the corresponding pressure) was 283.15K, the condenser condensation temperature (the arithmetic mean of the dew point and bubble point temperature in the condenser) was 313.15K, the vapor phase at the evaporator outlet was in the superheated state, the degree of superheat was 5K, the liquid phase at the condenser outlet was in the supercooled state, the degree of supercooling was 5K, and the adiabatic efficiency of the compressor was 0.75. Experiments were conducted using the cycle performance parameters of the refrigerants of examples 1 to 13, comparative examples 1 to 6 and R410A described above in the refrigeration system, respectively, to compare GWP, relative refrigerating capacity per unit volume Qv (ratio of refrigerating capacity per unit volume of R410A), relative coefficient of performance COP (ratio of coefficient of performance of R410A), compressor discharge temperature, compressor pressure ratio, among the refrigerants produced in each of the examples, and are recorded in table 3.
As can be seen from Table 3, the ternary environment-friendly mixed refrigerant provided by the invention has environmental performance far better than R410A and has lower GWP. Particularly, the GWP of all refrigerant formulas is less than 450, and the refrigerant has better environmental protection property; the relative unit volume refrigerating capacity of all refrigerant formulas is not lower than 0.95, the relative performance coefficient is not lower than 0.95, the refrigerating capacity and energy efficiency are basically equivalent to or obviously superior to those of R410A refrigerants, and the refrigerating capacity can be improved by 17% to the maximum extent; the compressor discharge temperature and pressure ratio for all refrigerant formulations are close to R410A, which is advantageous for the overall system.
Through experimental comparison, the technicians know that when the ternary environment-friendly mixed refrigerant comprises 4 to 72 percent of difluoromethane, 16 to 88 percent of trifluoroethylene and 4 to 24 percent of 1, 1-difluoroethane in terms of mole percent, the refrigerant consisting of difluoromethane, trifluoroethylene and 1, 1-difluoroethane, good environment-friendly characteristics and thermal performance equivalent to R410A can be obtained; for the refrigerant consisting of difluoromethane, trifluoroethylene and trifluoromethyl methyl ether, good environmental protection characteristics and thermal performance equivalent to R410A can be obtained when the ternary environment-friendly mixed refrigerant comprises, by mole percent, 4-68% of difluoromethane, 24-84% of trifluoroethylene and 4-20% of trifluoromethyl methyl ether. If only one of the three components is not in the molar ratio range, the loss of environmental protection performance or thermal performance can be caused, for example, the GWP of the comparative example 1 and the GWP of the comparative example 4 provided by the invention are higher than 450, and the environmental protection performance is poorer; the coefficient of performance of comparative example 2 and comparative example 5 is low; the volumetric cooling capacity of comparative example 3 and comparative example 6 was low.
