Question

Before you dispose of any system containing a refrigerant, you must ______.

1) Recover the refrigerant
2) Recycle the refrigerant
3) Reclaim the refrigerant
4) Release the refrigerant into the atmosphere

Answer 1

Before disposing of any system containing a refrigerant, you must recover the refrigerant; the condenser is the component that converts gas into liquid in an air conditioner. For a refrigerator with a COP of 3.0 that requires 200 J of work, it removes 600 J of heat per cycle from the cold reservoir and discards 800 J to the hot reservoir.

Step-by-step explanation:

Before you dispose of any system containing a refrigerant, you must recover the refrigerant. This is essential to prevent the release of refrigerants into the atmosphere, which can be harmful to the environment. The condenser is the component of an air conditioner that converts gas into liquid. In the context of heat pumps and air conditioners, the condenser works by releasing heat to a warmer area, changing the high-pressure gas into a liquid.

To address the question regarding a refrigerator's coefficient of performance, if a refrigerator has a coefficient of performance (COP) of 3.0 and requires 200 J of work per cycle, it means that the refrigerator removes three times the energy as work done on the system. Therefore, it removes 600 J of heat from the cold reservoir per cycle. Subsequently, because energy is conserved, the heat discarded to the hot reservoir per cycle is the sum of the work plus the heat taken from the cold reservoir, which equals 800 J (600 J from the cold reservoir plus the 200 J of work).
