Question

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

1) Replaced with a new refrigerant
2) Reused
3) Disposed of
4) d. Recycled

Answer 1

The refrigerant R-12 must be recycled, the air conditioner's condenser converts gas to liquid, and Freon-12 is a gas at room temperature.

Step-by-step explanation:

During servicing of a refrigeration system containing R-12, the refrigerant must be recycled. Recycling is the process where the refrigerant is cleaned of contaminants and reused in the same system or another system that is designed for the same refrigerant. This is an environmentally responsible practice to prevent the release of refrigerants like R-12, which is a chlorofluorocarbon (CFC) and can damage the ozone layer, into the atmosphere. Recycling also conserves resources and adheres to environmental regulations.

Regarding the component of an air conditioner that converts gas into liquid, the answer is the condenser. In an air conditioning system, the condenser is responsible for condensing the refrigerant gas back into a liquid form after it has absorbed heat from the indoor environment.

In regards to Freon-12, with a boiling point of -29.8°C, it would be a gas at room temperature, which is typically around 25°C. Since its boiling point is well below room temperature, this refrigerant is used for its phase change properties in refrigeration cycles.
