T he Correct Answer and Explanation is :
1. Primary Advantages of a Room Air Conditioner:
- Affordability: Room air conditioners are generally more cost-effective than central AC systems.
- Ease of Installation: They are relatively easy to install, especially window or portable units.
- Energy Efficiency (for Small Spaces): They can cool specific rooms without wasting energy on unoccupied spaces.
- Portability (in case of portable units): Some units can be moved from room to room as needed.
- Quick Cooling: They can quickly lower the temperature in small to medium-sized spaces.
2. Disadvantages of a Room Air Conditioner:
- Limited Coverage: They are only effective in small to medium rooms and not suitable for whole-house cooling.
- Aesthetic Impact: Window units can block natural light and may detract from a room’s appearance.
- Noise: Many room ACs produce noticeable noise during operation.
- Security Risk: Window-mounted units can create a potential entry point for intruders.
- Reduced Energy Efficiency (in larger applications): They may become inefficient if used in large spaces or multiple rooms.
3. What is a common problem with window air-conditioning units?
Correct Answer: Water leakage (condensate drainage problems)
Explanation
A common problem with window air-conditioning units is water leakage, typically caused by improper drainage of condensate water. During operation, window AC units remove heat and humidity from the air. The moisture condenses into water and collects in a drip tray or pan at the base of the unit. This water is normally expelled outside through a drainage hole or channel. However, several issues can interrupt this process and cause the unit to leak water inside the room.
One common cause is a clogged drain hole, which prevents water from exiting properly. Dust, dirt, or mold can build up and block the outlet. Another frequent issue is improper installation—if the unit is not tilted slightly backward (toward the outside), water can flow inward instead of draining out. Also, excessive humidity or overcooling the room can generate more condensate than the unit can handle efficiently, leading to overflow.
Additionally, damaged or missing seals between the unit and the window frame can allow rainwater or condensation to seep indoors. Poor maintenance, such as not cleaning filters and drip trays regularly, can also exacerbate the problem.
Water leakage not only reduces the cooling efficiency of the unit but can also damage walls, window sills, and furniture. It may even lead to mold growth if not addressed promptly. Regular inspection, proper installation, and routine cleaning are essential to prevent and fix this common issue in window air-conditioning units.
