| About Sample | |
| Samples is ok, but refrigerant is dangerous goods in law, ship agent will not accept mixed stuffing with other goods, so the high sea freight and delivery cost is better been taken into consideration | |
Comparison of R32 and R290
1. R290 and R32 have a relatively small amount of charge, the ODP value is 0, the GWP value is also much smaller than R22, the security level of R32 is A2, and the security level of R290 is A3.
2. R290 is more suitable for medium and high temperature air conditioning systems than R32. Pressure resistance design of R32 is higher than R290, and R32 has lower flammability than R290.
3. The dynamic viscosity of R290 is less than R32, and the pressure drop of the system heat exchanger is less than R32, which helps to improve the efficiency of the system.
4. R32 unit volume refrigeration capacity is about 87% higher than R290, R290 system should use a larger displacement compressor under the same refrigeration capacity.
5. R32 has a higher exhaust temperature, and the pressure ratio of the R32 system is about 7% higher than that of the R290 system, and the overall energy efficiency ratio of the system is about 3.7% lower.
6. The pressure drop of the R290 system heat exchanger is less than R32, which helps to improve system performance. But its flammability is far greater than R32, and has higher investment in safety design.
