AC Efficiency: Things You Need to Know

The heat and summer are here! Our air conditioning (AC) systems work harder as the temperature rises to keep us cool. However, are you aware of how these systems work and how to increase their effectiveness? Let's explore the science of air conditioning efficiency and learn some awesome money and energy-saving tricks!

The Cool Science of Air Conditioning

Basic thermodynamics is what air conditioning systems use to provide a comfortable indoor atmosphere. Here's a little explanation of how they operate:

• Evaporator Coil: Your interior air is heated by the evaporator coil, which causes the refrigerant to evaporate and transform into gas.

• Compressor: This gas is then heated even further by the compressor's subsequent high-pressure squeezing.

• Condenser Coil: The heated gas travels outside to the condenser coil, where it cools down and reverts to a liquid by releasing heat into the surrounding air.

• Expansion Valve: Lastly, the expansion valve allows the liquid refrigerant to cool down and become once more heat-absorbing.

What Impacts AC Efficiency?

Several factors play a role in how efficiently your AC system operates:

• Airflow and ventilation are critical for efficient cooling. Poor airflow can lead to hot spots and uneven cooling, forcing your AC to work harder to maintain a consistent temperature.

• Humidity has a direct impact on comfort and AC efficiency. AC decreases the humidity, which causes discomfort and health issues. The humidity should be around 30%-50%.

• Direct sunlight can significantly increase indoor temperatures, especially if windows are not properly shaded or treated. Use curtains, blinds, or reflective window films to block direct sunlight.

• Indoor plants can help improve air quality and slightly cool the air through transpiration. Place indoor plants around your home to enjoy their cooling benefits and enhanced air quality.

• Regular Maintenance is a must. Dirty or clogged filters can reduce the flow of air and thus result in more load and electricity consumption. Professional check-ups and frequent filter cleaning keep your AC running smoothly.
