  • Why it is forbidden to mix the R22 and R410A refrigerants

    Why it is forbidden to mix the R22 and R410A refrigerants

    Because R22 and R410A have different compositions and pressures, R410A needs to be filled in liquid, and the thickness of the copper tube of the machine is also different, so it is forbidden to mix the two refrigerants. Maintenance measuring instruments and quantitative refrigerant charging equipmen... read more

  • Do you really understand the differences and precautions between R410a and R22?

    Do you really understand the differences and precautions between R410a and R22?

    Analysis of physical properties and advantages and disadvantages of R410A R410A is a HFCs refrigerant mixed with two working fluids of R32 and R125 at a mass fraction of 50% and 50%. R410a refrigerant is non-flammable, ODP is 0, and global warming coefficient value GWP is 2340, so R410a is not a tru... read more
