Question

During servicing of a refrigeration system containing R-12, the refrigerant must be:

a.) Recovered
b.) Recovered and replaced with R-134a, no exceptions
c.) Vented
d.) Destroyed

Answer 1

During servicing, R-12 refrigerant must be recovered due to environmental regulations. The air conditioner's condenser converts gas into liquid. At room temperature, R-12 is a gas.

Step-by-step explanation:

During servicing of a refrigeration system containing R-12, the refrigerant must be recovered. It is important to follow this procedure to comply with environmental regulations that protect the atmosphere from harmful substances. R-12 is a chlorofluorocarbon (CFC) which can damage the ozone layer if released into the atmosphere.

The component of an air conditioner that converts gas into liquid is the condenser. The condenser plays a crucial role in the refrigeration cycle by releasing heat to the outside air and condensing the refrigerant from its gaseous state back into a liquid state.

Freon-12, also known as R-12, would be in a gaseous state at room temperature (25°C). This is because its boiling point is -29.8°C and room temperature is significantly higher than this boiling point.
