Physical properties of R290
At -25°C, the pressure of R 290 is similar to that of R22, 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. Therefore, the pressure of R290 is lower than R22. In other words, the suction temperature of R290 can be higher and the evaporation temperature can be lower. some. At 45°C condensing temperature, 32°C suction temperature and no subcooling, 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.
