R32 refrigerant basic performance

Chinese name: difluoromethane; molecular formula: CH2F2;

Physical properties: colorless, odorless, slightly burning (A2 level). Refrigerant R410A is non-toxic and non-flammable (A1 level);

Non-explosive, non-toxic, flammable, but still a safe refrigerant.

The thermodynamic properties of  R32 are similar to R410A.

R22 GWP value is 675.

our sum up:

1. The global warming coefficient of R32 refrigerant is 1/3 of R410A, which is more environmentally friendly than traditional R410A and R22 refrigerants, but R32 has a certain flammability.

2. Compared with R410A refrigerant, the saturation pressure of R32 is about 3%, the exhaust temperature is about 8-15 ℃, the power is about 3-5%, and the energy efficiency is about 5%.

3. Under the same operating conditions and the same operating frequency of the compressor, the cooling capacity and energy efficiency of the R32 system are about 5% higher than the R410A refrigerant.

4.R290 has:

Health hazards: simple asphyxiation and anesthesia. Short-term exposure to 1% propane does not cause symptoms; concentrations below 10% only cause mild dizziness; exposure to high concentrations can cause anesthesia and loss of consciousness; extremely high concentrations can cause suffocation.

Hazardous characteristics: flammable gas, mixed with air can form explosive mixtures, and there is a danger of burning and explosion when encountering heat sources and open flames.

5. Calculated based on the weight of the charge, the amount of R290 refrigerant is only 40% to 55% of R22 and R410a, which is less and more economical.

6. Low freezing point and larger latent heat of evaporation make the cooling rate faster in unit time; smaller isentropic compression ratio does less work to make the compressor work easier and extend the life of the compressor; small molecular weight, good fluidity and more pressure Low, reducing the load on the compressor. Using R290 refrigerant, the energy saving rate can reach 15 ~ 35%.
