How to Choose the Ideal Energy-efficient Air Conditioner

How to choose the ideal energy-efficient air conditioner for your living space

Selecting the right air condiditoner helps you keep your electricity bills low while preserving the environment.

Selecting the right cooling capacity for your rooms

For maximum energy efficiency, it is important to determine the right cooling capacity on your air conditioner. Firstly, have a good idea of the room size (volume) and layout (e.g; wide, two connecting rooms, high ceiling). An air conditioner that is too powerful will blast out cool air then shut off quickly once the desired set temperature is reached, only to repeat the process again, shortly. This repetitive process consumes a lot of energy. On the other hand, If an air conditioner is of insufficient capacity, it requires extra exertion to cool down your space, which guzzles up a lot of energy.

In addition, the amount of sunlight that enters the room, the presence/absence of windows, and the appliances used in the room must be taken into consideration when determining the ideal air conditioning capacity for your room.

Inverter technology:
a greener option

Inverter air conditioners are significantly more energy-efficient than non-inverter units.

The motor of the inverter compressor is able to vary its speed to adjust to the set temperature. Meanwhile a non-inverter's motor can only be turned on or off, unable to adjust its speed according to the workload. This consumes a lot more energy.

Enter Panasonic’s latest inverter air conditioner, the Premium Inverter, which reduces power consumption by adjusting its motor rotation speed once the desired temperature has been reached.

Energy efficiency ratings

To gauge how much energy an air conditioner consumes, compare how it stacks up against other models based on its energy efficiency indicators, such as the energy efficiency rating (EER) and cooling seasonal performance factor (CSPF) ratio. A higher rating generally means greater efficiency.

The Premium Inverter has not only achieved high EER for rated operations, but also has a high CSPF.

The Premium Inverter also has a smaller carbon footprint than conventional air conditioners as it uses the more eco-friendly R32 refrigerant.

Reasons for choosing this energy-efficient air conditioner

• Inverter technology: cut down your power consumption and enjoy powerful, fast cooling with the high-powered inverter compressor technology, P-TECh.

• Energy efficiency: the Premium Inverter’s high energy-efficiency ratings mean a smaller electricity bill and less damage to your wallet.

• Eco-friendly refrigerant: the Premium Inverter uses the more eco-friendly R32 refrigerant, which has zero impact on the ozone layer and consumes less energy.
