The six commonly used refrigerants, has four is inflammable and explosive!

Refrigerant is also called the refrigerating agent, is the working medium of refrigeration cycle, the use of phase change of the refrigerant to transfer heat, both the refrigerant in the evaporator vaporization heat absorption, condensed in the condenser heat release. The current can be used for material has more than 80 kinds of refrigerants, ammonia and fluorine is the most commonly used. 。 。

refrigerant is also called the refrigerating agent, is the working medium of refrigeration cycle, the use of phase change of the refrigerant to transfer heat, both the refrigerant in the evaporator vaporization heat absorption, condensed in the condenser heat release. Current can be used for material has more than 80 kinds of refrigerants, ammonia and freon is the most commonly used class, water and a small number of hydrocarbons, etc. The following six is the most commonly used models, but note that there are four is the refrigerant or explosive, must be careful when using. 1, R22

belongs to freon refrigerant R22 refrigerant also, a the methane of cl, chemical name is 2 fluorine chemical formula for CHF2Cl.

temperature refrigerant R22 refrigerant is medium pressure, the boiling point temperature of - 40. 8 ℃, freezing point to - At 96 ℃, 160 ℃, critical temperature and critical pressure of 4. 974MPa 。 R22 burning explosion, toxicity is small, but understand ability is very strong, and leaks are difficult to find. Unit volume of R22 and ammonia refrigerants. While preparing the lowest temperature can reach - 80 ℃, but not the economy.

2, r410a

R410A is made up of R32 and R125 two working medium according to the mixture of 50% and 50% mass fraction of HFCs refrigerant. R410A phase change temperature glide less than 0. 2 ° C, so don't have to put off filling refrigerant leak. 410 a refrigerant volume and pressure higher than that of R22, running 50% higher than that of pressure 60%. R410a running noise ratio significantly lower 2 - R22 compressor 4 db.

since R401A high pressure, high density allows many refrigerant pipe diameter decreases, the compressor size and capacity can be greatly reduced; High thermal conductivity, viscosity of liquid phase and R410A is obviously better than the low has the transmission properties of R22.

3, R32

R32 is short for methylene fluoride, R32 colorless, tasteless, mild combustion ( A2 level) In the air combustion limit is 14% ~ 31%, meet the fire will burn.

R32 also has lower viscosity coefficient and high thermal conductivity. Although R32 advantages, R32 is inflammable, explosive refrigerant; Air-conditioning installation and maintenance is dangerous work, now plus R32 uncertainty, safety issues to consider.

note! R32 refrigerants need pumping air into vacuum state, banned flame!

4, R290

R290 ( Propane) Also called cold coal, is a new kind of environmental protection refrigerants, mainly used for central air conditioning, heat pump air conditioner, air conditioning and other small household refrigeration equipment. R290 as a kind of hydrocarbon refrigerants, ODP value is 0, GWP value is less than 20, with R600a, everything & amp; Compared r404a, has prominent advantages on the cooling performance. Because of its features, flammable and explosive perfusion has been curbed, security level for A3.

note! R290 to vacuum, air mixture can form explosive mixture, when heat and flame is in danger of burning explosion, must open fire! 5, R600a

R600a, isobutane, is a kind of excellent performance of the new type of hydrocarbon refrigerants, derived from natural ingredients, no damage to the ozone layer, without the greenhouse effect, green environmental protection. Characterized by a large latent heat of evaporation and cooling ability; The flow performance is good, delivery pressure is low, low power consumption, load temperature picks up speed. Compatible with all kinds of compressor oil. Colorless gas at room temperature, under pressure from its own colorless transparent liquid. R600a is mainly used to replace the refrigerant R12, now used for household refrigerator equipment.

R600a is also a flammable gas, mixed with air to form explosive mixture, heat and flame is in danger of burning explosion. Contact with the oxidant violent reaction. Its vapor is heavier than air, can spread in the low to very far place, fire will fire back to combustion.

6,汉尼( Ammonia)

汉尼( Ammonia) Refrigerant, ammonia is medium temperature refrigerants, pure ammonia had no adverse effect on oil, but there is water, will reduce the refrigeration oil lubrication, pipe and valve parts in ammonia refrigeration systems are using copper and copper alloy. R717（ Ammonia) Mature synthesis process, making is easy, the price is low, does not destroy the ozone layer, without the greenhouse effect. But ammonia vapor colorless, has a strong stimulating smell. Ammonia has bigger toxicity to human body, when ammonia liquid splashes on the skin can cause frostbite.

when the ammonia vapor in the air volume reached 0. 5 - 0. 6% when can cause explosion. So the concentration of ammonia in air in the room must not exceed 0. 02mg/L。 Ammonia is not easy to burn at room temperature, but when heated to 350 ℃, then decomposed into nitrogen and hydrogen, hydrogen to explode after mixed oxygen in the air.
