Answer :
Final answer:
It is not good practice to re-use refrigerant from a system that had a compressor burnout without proper processing, as it could harm new components. The refrigerant should be purified before reuse to maintain the system's efficiency.
Explanation:
The question asks whether it is good field practice to re-use the recovered refrigerant in a system after repairing an electrical motor failure such as a compressor burnout. The answer to this is false. It is not a good practice to re-use the refrigerant without proper processing because the refrigerant may be contaminated due to the motor burning out. Contaminants from the burnout can cause harm to the new system components and degrade the performance of the refrigerant. Instead, the refrigerant should be recovered, purified, and possibly recycled, ensuring that it is clean before reusing it again. This process helps in maintaining the cooling coefficient of performance (COP cooling) which is crucial for the efficiency of the refrigeration cycle.
