What is the potential consequence of failing to evacuate a low-pressure refrigeration system before servicing?

• A. Improved system efficiency
• B. Increased risk of contamination
• C. Lower energy consumption
• D. Enhanced refrigerant stability

Answer: (B)

The potential consequence of failing to evacuate a low-pressure refrigeration system before servicing is an increased risk of contamination. When a refrigeration system is not properly evacuated, moisture and air can enter the system. This can cause several issues, including the formation of acids and ice within the system due to the low temperatures involved. Moisture can lead to corrosion of components, while air can disrupt the normal operation of the system by affecting pressure and efficiency. Contamination in a refrigeration system can result in significant operational problems, including reduced functionality and increased maintenance costs. Proper evacuation helps to ensure that the system operates efficiently and reliably by removing unwanted gases and moisture before any servicing or repairs are conducted.
