Answer

The process is called **evacuation**.

Solution

The correct answer is: **(D) evacuation** **Explanation:** In the HVAC/R (Heating, Ventilation, Air Conditioning, and Refrigeration) industry, **evacuation** refers to the process of removing both air and water vapor from a system. This is a crucial step before charging the system with refrigerant to ensure optimal performance and to prevent potential contamination or inefficiencies. Evacuation typically involves the use of specialized vacuum pumps to create a deep vacuum, effectively eliminating non-condensable gases and moisture that could impair the system's functionality. - **Degassing** generally refers to the removal of gases but doesn't specifically encompass both air and water vapor in the context of HVAC/R systems. - **Leak justification** involves verifying or identifying leaks within the system, not the removal of substances. - **Moisture removal** specifically targets the elimination of water vapor but doesn't address the removal of air. Therefore, **evacuation** is the most comprehensive term that accurately describes the removal of both air and water vapor in the HVAC/R industry. **Answer:** (D) evacuation

Bonus Knowledge

The correct answer is (D) evacuation. In the HVAC/R industry, evacuation is the process of removing air and moisture from a refrigeration system to ensure it operates efficiently and to prevent damage to the system. This vital step helps in achieving optimal performance and longevity of the equipment, as trapped moisture can lead to corrosion and other issues. When performing evacuation, it's important to use the right equipment, such as a vacuum pump, and to monitor the vacuum level for achieving the correct depth of evacuation, usually around 500 microns or lower. A common mistake is not allowing enough time for the process; rushing through it can leave residual moisture that can wreak havoc on the system later on!
