PEA advises on cost-effective air conditioners amid Thai heat

In this sweltering heat, many turn to air conditioners for relief, yet the cost of electricity remains a concern. The Provincial Electricity Authority (PEA) of Thailand has provided guidance on how to use air conditioning efficiently without incurring high electricity bills.

The PEA recommends selecting the right size of air conditioner, as measured in British Thermal Units (BTU), for the room.

An air conditioner with 9,000 to 21,000 BTU is suitable for small to medium spaces such as apartments, while units with 21,000 to 30,000 BTU are better for medium to large rooms such as living rooms and halls. For large spaces such as home offices, restaurants, or cafes, a 30,000 to 36,000 BTU air conditioner is appropriate.

Setting the air conditioner to 26 to 27 degrees Celsius and using it alongside a fan may help circulate air, and cool the room quicker, potentially reducing electricity costs by 10%.

Regular maintenance is also essential. Cleaning the air conditioner’s filter every month and washing the unit every six months can remove dust and ensure it operates at full capacity.

Turning off the air conditioner when not in use is more energy-efficient than frequently switching it on and off. The highest power consumption occurs when the air conditioner starts, so frequent switching leads to higher electricity usage.

Using a timer to set when the air conditioner should turn off, especially at night when the temperature drops, can also save on electricity costs.

Ensuring that doors and windows are closed tightly will prevent cool air from escaping and warm air from entering, which makes the air conditioner work harder to maintain the desired temperature.

The PEA also shared some insights on the use of inverter air conditioners, which can cool rooms quickly and efficiently. Many users have misconceptions about air conditioner usage that they believe save energy, but in reality, these practices could lead to higher electricity bills.

As summer temperatures rise, these tips from the PEA offer practical ways to stay cool while managing energy consumption and keeping electricity bills in check.
