How Does an Inverter Function with Air Conditioners?

An inverter functions with air conditioners by converting direct current (DC) to alternating current (AC). This process allows the air conditioner to operate efficiently.

The main components involved are the inverter, compressor, and fans. The inverter controls the compressor’s speed based on the cooling demand.

When the temperature rises, the thermostat signals the inverter to activate the compressor. The inverter adjusts the electrical frequency, which changes the compressor’s speed.

A higher speed cools the air quickly, while a lower speed maintains the desired temperature without excessive energy use. This operation reduces fluctuations in energy consumption and provides consistent cooling.

Overall, an inverter enables precise control of the air conditioning system, leading to energy efficiency and enhanced comfort.

To accurately size an inverter for your air conditioner needs, you must consider the air conditioner’s power requirements, the starting and running wattage, and the inverter’s efficiency.

The power requirements of your air conditioner determine the inverter size. Air conditioners have two wattage ratings: starting (or surge) wattage and running wattage.

• Starting Wattage: This is the amount of power your air conditioner needs to start up. Typically, this wattage is significantly higher than the running wattage. According to EnergyStar, the starting wattage can be up to three times greater than the running wattage.
• Running Wattage: This is the amount of power the air conditioner consumes while it is operating. It remains constant once the unit is running. For example, a 1.5-ton air conditioner may require about 1,500 watts to run.

To size the inverter accurately, you should select an inverter that can handle both the starting and running wattages.

• Calculate Total Wattage: Add the starting and running wattages. If the running wattage is 1,500 watts and the starting wattage is 4,500 watts, the total wattage requirement would be 4,500 watts.
• Inverter Efficiency: Consider the inverter’s efficiency. Most inverters have an efficiency rating of around 85% to 95%. To ensure you have sufficient power, divide the total wattage needed by the inverter efficiency percentage. For instance, if your total wattage requirement is 4,500 watts and your inverter is 90% efficient, you would divide 4,500 by 0.90, giving you a requirement of about 5,000 watts for the inverter.

Selecting an inverter with a slight margin of excess capacity is advisable. This accounts for any additional power loads that may be drawn, such as fans or lights. For example, if your total calculation indicates you need 5,000 watts, choose an inverter rated for 6,000 watts to ensure reliable performance.

Following these steps ensures that you select an appropriately sized inverter to support your air conditioning needs efficiently.
