1. Physical properties of R290
At -25℃, the pressure of R290 is similar to that of R22, which is higher than R134a and lower than R404A. The standard boiling point of R290 is similar to R22, and the critical temperature is also close to R22, but the exhaust temperature of R290 is lower than that of R22, so the pressure of R290 is lower than R22. The volumetric cooling capacity of R290 is similar to that of R22, which is 1.5 times that of R134a. It is 2.5 to 3 times that of R600a, which means that for household refrigerators with the same cooling capacity, the structure of the R290 refrigerator refrigeration system is smaller and the overall space occupied by the refrigerator is reduced.
2. The safety performance of R290
The disadvantage of R290 as a refrigerant is the flammability of R290. The compressor, condenser, evaporator, pipeline and other components of the refrigeration system may cause the leakage of working fluid. Therefore, the maximum filling volume of R290 in the refrigerator should be controlled at about 150g. In order to ensure safe operation, the refrigeration system and control components should be arranged in different spaces. The R290 refrigeration system should be closed, and leak detection should be strictly carried out before charging the refrigerant.
3. R290 refrigeration system performance
The theoretical COP values of R290, R600a and R134a are higher than those of R22 at the evaporating temperature of -25°C and the condensing temperature of 45°C. The COP values of R290 and R134a are similar. Just like R134a, R 404A and R600a, suction superheat is very important to the performance of the R290 refrigeration system, which can improve the COP of the refrigeration system, while R22 has little effect.
