Usually according to the standard evaporation temperature of refrigerant, it is divided into high, medium and low temperature. The standard evaporation temperature refers to the evaporation temperature under standard atmospheric pressure, that is, the boiling point.
Low-pressure high-temperature refrigerant: the evaporation temperature is higher than 0℃, and the condensing pressure is lower than 29.41995×104Pa. This type of refrigerant is suitable for centrifugal refrigeration compressors in air conditioning systems.
Medium pressure medium temperature refrigerant: Evaporation temperature -50 ~ 0 ℃, condensing pressure (196.113 ~ 29.41995) × 104Pa. This type of refrigerant is generally used in ordinary single-stage compression and two-stage compression piston refrigeration systems.
High-pressure low-temperature refrigerant: the evaporation temperature is lower than -50℃, and the condensing pressure is higher than 196.133×104Pa. This type of refrigerant is suitable for the low temperature part of the cascade refrigeration device or the low temperature device below -70 ℃.

R32 refrigerant is easily soluble in oil and hardly soluble in water. The ozone destruction potential ODP is 0, and the global warming coefficient value GWP is 675. The pressure is about 60% higher than R22. Products need to withstand high pressure, and tools and equipment used for maintenance also need to withstand high pressure. The pressure is equivalent to R410A, and the thermal performance of R32 and R410A is very close.
In fact, we have published many Knowledge of R32 refrigerants on our website, many friends are asking me, R32 refrigerants are flammable and explosive, why do many manufacturers use R32 refrigerants? Compared with R22, R32 refrigerant has a CO2 (carbon dioxide) emission reduction ratio of up to 77.6%, while R410A has a CO2 (carbon dioxide) emission reduction of 2.5%.
R32 Main Advantages:
1. Global Warming Potential (GWP): R32 has a lower GWP (675) compared to R22 (1810) and R410A (2088). The lower GWP of R32 means it has a lower impact on the environment compared to R22 and R410A.
2. Pressure: R32 operates at a lower pressure compared to R22 and R410A, which can result in smaller and lighter components for air conditioning systems.
3.Cost: R32 is generally less expensive compared to R22 and R410A, making it a more cost-effective option for air conditioning systems.
