What are the differences between common refrigerants

refrigerants in daily life is very common, refrigerant type is various, but choosing refrigerants, there are many factors to consider, because choose any kind of refrigerant will all the workings of the air conditioning system, reliability, cost and market acceptance of a certain impact. So that we are interested in, new refrigerant because of its heat transfer and pressure drop caused by the different refrigerant transmission function is different, this will eventually on system planning and system function have a significant impact. Let's briefly discuss the several common difference features of difference between refrigerants.

at present commonly used refrigerants R410a, everything, R407C, R22, several common models

R134a has a small capacity than that of R22, the pressure is lower than R22. Because of these characteristics, the same to everything air-conditioning demand a greater displacement compressor, evaporator, condenser, and pipeline. The result is that, as a result of production and operation a and R22 system of the same amount of cold, R134a has a system would demand higher capital.

volume and pressure of R407C and R22 is drawing near. Therefore, as long as the short adjustment system design can make the original R22 system is suitable for R407C system. However, the system can effect comparing is the original system will be reduced by about 5%. This is because the relative to other refrigerant R407C will have up to 6 degrees of temperature drift. Thus R407C system under the same standard will reduce heat transfer when the condenser and evaporator, influence system can effect comparing.

R410A capacity and pressure is higher than that of R22, working pressure is higher than 50% 60%. High pressure and high gas density as a result, not only can use the smaller displacement compressor, also can use the smaller the diameter of the pipe and valve. The use of high pressure exhaust valve to eliminate system condensing pressure brings hidden trouble. Thick compressor housing system has higher operation pressure. A further advantage of compressor made some heavy, namely R410A running noise than noticeably lower 2 - R22 compressor 4 db.

compared with R22 system, R410A system has an obvious advantage of heat transfer - 5% higher than 35% higher heat transfer of evaporator, condenser. And everything heat transfer coefficient were lower than that of R22 and R407C system. Equal mass flow rate, the smaller the pressure drop of R410A, allow them to use more than the refrigerant R22 or other small piping and valves. This cut for R410A system more information capital more may and in the long piping console and many have more advantages in the online system.

now whether you already understand the differences between those refrigerants, refrigerant choice should be more reference in later days. If there is demand for refrigerants, welcome consultation discussion with us, we wholeheartedly at your service.
