R32 refrigerants properties

2019 - 02 - 19 is short for methylene fluoride, refrigerant R32 is a coolant with zero ozone depletion potential, into a gas at room temperature, under pressure from its own colorless transparent liquid, soluble in oil, poorly soluble in water. Mention R32, will have to review the application of air conditioning refrigerant history, as well as some commonly used refrigerants. R22 is a kind of controlled air conditioning industry decades of refrigerants, due to large harm to the ozone layer, according to the Montreal protocol and the Kyoto protocol, the refrigerant exit time getting closer. Therefore, to find suitable alternative refrigerant has been the important task air conditioning industry in recent years. It is in this context, refrigerant r410a and R290 both walked into the our field of vision. R290 hydrocarbons inflammable and explosive characteristics & other people; A fearful & throughout; And R410A, although do not have a harm to the ozone layer, exacerbate global warming. All in all, both R410A and R290, did not become a mainstream market conditions. R32 as a new generation of energy conservation and carbon reduction environmental non-toxic refrigerants, become an excellent choice. R32 and the difference between the refrigerant and refrigerant R410A compared with R410A, R32 about 3% higher saturation pressure, exhaust temperature 8 - high 15 degrees, high power 3 - 5%, can effect comparing high about 5%. Figure 1 p machine performance parameters of the refrigerant. 1, R32 combustible, but non flammable gas, colorless, normal pressure is colorless transparent liquid; 2, R32 soluble in oil, poorly soluble in water. 3, R32, R22, R410A and toxicity of R290 are belong to the class A security level; 4, R32 light temperature is 648 ℃, burning cap of 33. 4%, the minimum 12. 7%; 5, filling quantity of R32 system less than R10A system. How to see the flammability of R32 refrigerants? 1, the level of security. International standard ISO817 R32, ISO5149 have security level is defined as A2L, namely combustible are lower than those of A2 class. Note: 1, the burning of grade: 1 & ndash; Don't burn; 2 - Moderate combustible; 3 - Highly flammable. 2 l - Micro combustible; 2, Japan will R32 refrigerant is defined as a flammable refrigerant; 2, R32 filling volume is much less than R410A. 3, R32 combustion must have the four necessary conditions of the lighting source of refrigerant 5, 4, R32 R32 refrigerant burning sustainability R32 application note 1, if you need longer copper tube, need to use double copper tube, thickness & ge; 8mm; 2, installation, wiring and cabling note with R22 refrigerant pipe diameter difference; 3, the machine and connecting pipe must be vacuum, pressure maintaining, make sure the system without leakage, are not allowed in the form of emptying instead of vacuum; 4, for the extension of copper tube, it is necessary to add refrigerant: according to the circumstance when connecting pipe is less than or equal to 8 m, if don't need to add refrigerant, connecting pipe more than 8 m ( The liquid pipe shall prevail) , on the basis of 5 m each more than 1 m to add refrigerant, must adopt electronic said additional quantitatively, do not allow the feeling or additional according to parameters such as current, pressure.
