Summary: It is prohibited by the Environmental Protection Agency (EPA) to mix refrigerant in a heating, ventilation and air conditioning (HVAC) system. In my (2) R22 based HVAC systems, the low pressure side is 40 and 45 degrees Fahrenheit (F) while the high pressure side is 110 and 115 degrees.

Summary: It is illegal for the Environmental Protection Agency (EPA) to mix refrigerant in a heating, ventilation and air conditioning (HVAC) system. In my (2) R22 based HVAC systems, the low pressure side is 40 and 45 degrees Fahrenheit (F) while the high pressure side is 110 and 115 degrees.
The best replacement for Freon R22 is usually R407c. It has very low capacity loss (0-5%) compared to R22 and is cheaper than many other R22 replacement refrigerants. If a system already contains R22, new refrigerant cannot be used to add R22.
No you can not. In summary, R410A and R22 are refrigerants. They are both good refrigerants and they both work, but they need to be fed into the system at different pressures. R410A is a high pressure system and R22 is a low pressure system.
The influence of the evaporation temperature on the compressor supply for R22 and for the two alternative refrigerants at the condensing temperature of 50 ° C is shown in Fig.
R22 is the abbreviation for the halogenated hydrocarbon compound CHClF2 (monochlorodifluoromethane), which is used as a refrigerant. R stands for refrigerant. In the number 22, 2 indicates the number of fluorine atoms in the compound. The boiling point of R22 is 40.8 degrees Celsius (41.4 degrees F).
For a low pressure gauge, a reading of 25 pounds per square inch (psi) at 40 psi is optimal. On the other hand, a high pressure gauge should read between 225 psi and 250 psi.
IMPORTANT TO UNDERSTAND WHAT THE NORMAL SIZE IS.
Manifold sets should be 750 psi (high side) and 200 psi (low side) with a slight delay of 500 psi. Use hoses with a working pressure of 750 psi. Leak detectors must be of the HFC type. R410A is compatible with POE oils.
The high-side connection should be in the line between the condenser and the expansion valve or vent line, while the low-side connection should be in the return line between the evaporator (firewall) and the compressor. The upper side door is larger than the lower side door.
The high readings on the low side (along with the normal readings on the high side) are due to a fault in the thermostat switch. The thermostat may be in the wrong temperature range. For normal measurements, replace the thermostat switch with a local technician.
Excess refrigerant accumulates in the condenser and causes high subcooling and high output pressure. When a TXV collector system is included in the liquid line, most of the refrigerant collects in the collector and part in the condenser. This leads to low hypothermia and low head pressure.
