What is the difference between the two refrigerant pipes for air conditioners? The purpose of connecting the outdoor unit and the indoor unit is to connect the indoor unit and the outdoor unit. The refrigerant (freon, also called refrigerant) passes through the connecting pipe. For example, in the c... read more
Why should the refrigerant be filled in liquid form? What are the best methods of filling? Refrigerants can be divided into three categories: single working fluid refrigerants, non-azeotropic mixed refrigerants, and azeotropic mixed refrigerants. Regardless of whether the single-working-substance re... read more
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
Refrigerants can be divided into three categories: single working fluid refrigerants, non-azeotropic mixed refrigerants, and azeotropic mixed refrigerants. No matter whether the single-working-substance refrigerant is gaseous or liquid, its composition will not change, so it can be charged into gase... read more
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
