What is the primary water source for a water cooled recovery unit's condensing coil? (A) A) De-ionized water (B) B) Local municipal water supply (C) C) Condenser water (D) D) Chilled water from the evaporator

The primary water source for a water-cooled recovery unit's condensing coil is **(C) Condenser water**. **Explanation:** In a water-cooled recovery unit, the condensing coil requires a continuous supply of water to effectively remove heat from the refrigerant. This water is specifically designated as **condenser water**, which typically circulates through a cooling tower system to absorb and carry away the heat. Unlike municipal water, which is general-purpose and may contain impurities, condenser water is managed to maintain optimal performance and efficiency of the condensing coil. - **(A) De-ionized water**: Generally used in applications where mineral-free water is necessary, but not typically the primary source for condensing coils. - **(B) Local municipal water supply**: While it could be used, it's not specifically tailored for condenser needs and may require treatment. - **(D) Chilled water from the evaporator**: This refers to the water used in the evaporative side of the system, not the condensing side. Therefore, **Condenser water** is the most accurate and appropriate primary water source for the condensing coil in a water-cooled recovery unit. **Answer:** **C) Condenser water**
