The difference between the analytic refrigerant R404A and R507

refrigerant r404a and R507 introduction believe everyone through introducing the before to have a certain understanding, below small make up for all of the content is the difference between the refrigerant R404A and R507, want to know friends following the introduction of small make up have a look at the following article. 1, refrigerant R404A is by R125 / R143a/everything by 44% / 52% 4% mixed together, R507 consists of R125 / R143a by 50% / 50% mixed together, look from the composition of mixed composition of R404A three ingredients already contains two R507 ingredients. Both kinds of refrigerant ODP is zero, does not damage the ozone layer. 2, R404A and R507 pressure, temperature, pressure on the table data show that the pressure is almost the same between them, the system will not cause any influence, if you usually pay attention to the use of system components, especially the expansion valve on the label that is Shared by R404A and R507. 3, R404A is azeotrope, filling liquid should be used when filling, and R507 is azeotrope. 4, R404A reduce everything to be increased by mass transfer resistance in the heat transfer coefficient is a message, and the heat transfer coefficient of R507 above R404A. 5, and use the results from the current producers, R507 effect than R404A cooling speed is faster. 6, from the price comparison, R507 is 30 - higher than R404A - 40%. Each performance close to 7, R404A and R507A, R404A compressor power consumption is higher than R507A 2. 86%; Low-pressure compressor exhaust temperature is higher than R507A 0. 58%, high pressure compressor exhaust temperature is higher than R507A 2. 65%; The COP is higher than R507A 0. 01; The middle temperature is lower than R507A 6. 14%.
