It is necessary to remove the door(s) and the refrigerant. The doors so a child can't get trapped in the discarded frig, the refrigerant so it doesn't leak out.
tis is normal for an expansion valve/receiver dryer type
Request your recovery questions to be removed, however, this process takes 14 days.
Refrigerant should be removed from the condenser outlet when:
The most heat is removed from the refrigerant during the condensing process when it changes from a gas to a liquid state. This typically occurs in the condenser where the high-pressure, high-temperature refrigerant releases heat to the surroundings, causing it to condense.
Thermal energy is absorbed from inside the refrigerator by the evaporator coil, which then turns the refrigerant gas into a liquid. This liquid is then pumped through the condenser coil on the back of the fridge where the heat is released into the surrounding air. The refrigerant then returns to the evaporator coil to repeat the cycle.
When the maximum pressure of the refrigerant is achieved in the condensor and the maximum temperature differential is acheived between the condensor coil and the surrounding medium. (air, water, or other)
If an HFC-134a AC system still has pressure, additional recovery is necessary to ensure that all refrigerant is safely removed from the system. This typically involves using a refrigerant recovery machine to extract the remaining refrigerant until the pressure gauge indicates a vacuum or a safe level. It's important to follow proper procedures to prevent any leaks or environmental harm, adhering to regulations regarding refrigerant handling. Always ensure that the system is properly evacuated before maintenance or disposal.
When r-500 is recovered from an appliance, it is a refrigerant that is being removed and collected for proper disposal or recycling. r-500 is a blend of R12 and R152a, both of which are ozone-depleting substances, so the recovery process is necessary to prevent environmental harm.
