What is Portable Air Conditioner? How Do Portable Air Conditioners Work?

A portable air conditioner is a self-contained cooling unit designed to cool individual rooms. It usually features wheels, making it easy to move between rooms.

Unlike split or ducted air conditioning systems, portable air conditioners don’t require permanent installation on walls or ceilings.

They only need an exhaust hose to expel hot air, usually through a window. Setting up this unit doesn’t require professional help, as it can be done with basic tools and DIY skills.

Portable air conditioners are more cost-effective compared to split or ducted systems. They come with lower initial costs and eliminate the need for professional installation and maintenance, saving on labor costs.

To fully appreciate how portable air conditioners work, it's important to understand their operation. Here’s a step-by-step breakdown:

Air Intake: The portable AC draws in warm air from the room.
Cooling: The warm air passes over the evaporator coils filled with refrigerant, transferring the heat into the refrigerant, thus cooling the air.
Air Output: The cooled air is then circulated back into the room through a vent to lower the room’s temperature.
Heat Exhaust: The heat absorbed by the refrigerant is expelled outside through an exhaust hose.
Condensation Removal: The moisture collected on the desiccant surface is either evaporated into a reservoir or drained out.

What You Should Consider When Buying a Portable AC?

When choosing the best portable air conditioner, consider these key features:

Cooling Capacity (BTUs): Higher BTU ratings mean better cooling. For small rooms, 8,000–10,000 BTUs is sufficient; for larger spaces, 12,000 BTUs or more is recommended.
Energy Efficiency: Look for units with high EER ratings or ENERGY STAR® labels to save on electricity and reduce environmental impact.
Noise Levels: Opt for models with noise levels between 50-60 dB for a quieter cooling experience, especially for bedrooms or offices.
Exhaust Hose: Flexible hoses are easier to install and offer better performance compared to fixed-length ones.
Additional Features: Features like a timer, remote control, and air filters can enhance convenience and performance.
Size and Portability: Choose a unit that's the right size for your space. Most portable ACs have wheels, but larger models may be less portable.

1. Poor Cooling

Clean the Air Filter: A clogged filter restricts airflow, reducing cooling efficiency.

Inspect the Exhaust Hose:Make sure it’s properly connected and free of blockages.

Check BTU Rating: Ensure the unit’s cooling capacity matches the room size.

2. Water Leakage

Examine the Drainage: Confirm that the condensation tank is not full and draining properly.

Inspect the Hose: Look for cracks or leaks in the drainage hose.

3. Excessive Noise

Check for Loose Parts: Ensure all parts are securely attached, excluding any spare parts.

Inspect the Fan Blades: Clean or replace damaged fan blades for quieter operation.

How Do You Install a Portable Air Conditioner

Installing a portable air conditioner is a straightforward process. Here’s a simple guide:

Choose the Right Location: Place the unit near a window for easy venting of hot air. Make sure there’s enough space for air circulation and that the exhaust hose can reach the window.
Assemble the Exhaust Hose: Attach the exhaust hose to the unit, ensuring it’s securely fitted to prevent leaks.
Install the Window Kit: Most portable ACs come with a window kit that fits most window types. Place the kit in the window, and adjust it to the size of the opening. Seal any gaps around the window with the provided foam strips.
Connect the Exhaust Hose: Attach the other end of the exhaust hose to the window kit. Ensure the hose is as straight as possible to prevent air resistance.
Plug in and Power Up: Connect the unit to a power outlet. Turn on the portable air conditioner and set the desired cooling mode and temperature.
Maintain Proper Venting: Ensure the exhaust hose is directed outside, and check that the window kit is securely in place.

How to Maintain Your Portable Air Conditioner

Maintaining your portable air conditioner regularly is key to ensuring it performs optimally. Here's how:

Filter Care: Routinely clean (every 1-2 weeks) or replace your unit's filters, especially if they're reusable or damaged, to maintain good airflow.
Condensation Management: If your model lacks self-evaporation, periodically empty the water reservoir according to the manufacturer's guidelines to prevent water buildup.
Exhaust Hose Check: Inspect the exhaust hose for any blockages or bends that could hinder hot air expulsion. Ensure it's securely connected to prevent hot air from re-entering the room.
Coil Cleaning: Keep the evaporator and condenser coils free of dust and debris through regular cleaning. This practice is crucial for efficient heat exchange and sustained cooling power.

FAQs about Portable Air Conditioner

1. What size portable air conditioner do you need?

Room Size	Example	Approx. Capacity (BTU)
Small	Up to 20 m² (Bedroom, Small Office)	8,000 - 10,000 BTU
Medium	20 - 30 m² (Living Room, Larger Bedroom)	10,000 - 12,000 BTU
Large	30 m² and above (Large Living Room, Open Space)	12,000+ BTU

2. Can you use Newentor portable air conditioner without an exhaust vent?

No, you cannot use the Newentor portable air conditioner without an exhaust vent. The exhaust vent is necessary for venting the hot air out of the room. Without it, the unit would recirculate the warm air, making it unable to effectively cool the room. Proper ventilation is required to maintain the cooling process and ensure efficient performance. The exhaust hose must be connected to a window or another outlet to expel the hot air outside.

3. What is the lifespan of a portable air conditioner?

There are some excellent products in the market that offer a standard three-year warranty, such as Aldi Stirling, Chiq, Olimpia Splendid, and TCL, but there's still room for improvement.

DeLonghi and Chiq go a step further, offering five-year and seven-year warranties on the motor and compressor, respectively. However, Newentor’s portable air conditioner stands out with an impressive 10-year warranty, offering exceptional reliability and peace of mind.
