The amount of R22 refrigerant a walk-in cooler holds can vary significantly based on its size and design. Typically, a walk-in cooler can contain anywhere from 5 to 20 pounds of R22, although larger units might require more. It's essential to consult the manufacturer's specifications or service documentation for the exact refrigerant charge required for a specific model.
There are so many Refrigerants in use that there is no way to answer this question. Best guess R22 or R134A

The price of R22 refrigerant can vary greatly depending on supply and demand. As of 2021, it can range from $30 to $80 per pound. So, 6 lbs of R22 could be worth between $180 to $480.
Most new equipment is built for and charged with R410a, a refrigerant with much higher pressures than the R22 used for decades, R22 units are still available, dry charged however, you must fill them with R22 onsite. This is how new R22 compatible equipments being sold still.
Absolutely not ... R410 operates at much higher pressures than R22, and mixing would do nothing but contaminate both refrigerants (and possibly mess up your system)
New, i think it is £105,000 for an R22. Yes about 3,00,000 USD.
Current price depending on location $40-60 per lb.
Wal-Mart do not have r22 freon, this is a false ad.

No
R22 gauges are designed for use with R22 refrigerant, and while they can technically be used to read the pressure of R416A, the accuracy may not be reliable. R416A has different pressure-temperature characteristics compared to R22, so using R22 gauges could lead to misinterpretation of the readings and potentially improper servicing. It's advisable to use gauges specifically designed for the refrigerant in use to ensure accurate measurements.
no. it is not a good idea. new hfc refrigerants require a different type of oil than the R22 units. the new refrigerants typically run at higher pressures than the R22 units.
