To determine the required capacity of an inverter for a 1.5HP air conditioner, we need to consider both the power consumption of the air conditioner and the power factor.
Air Conditioner Power Consumption: The power consumption of an air conditioner is typically given in terms of Watts (W) or kilowatts (kW). To convert the power rating from horsepower (HP) to kilowatts, we can use the following conversion:
1 HP = 0.7355 kW
Therefore, a 1.5 HP air conditioner is approximately equal to 1.1 kW (1.5 * 0.7355).
Power Factor: The power factor is a measure of the efficiency of electrical power usage. It can vary for different devices, but for air conditioners, it is typically around 0.9 to 1.0.
Now, let's calculate the apparent power (KVA) required for the 1.5 HP air conditioner:
Apparent Power (KVA) = Power Consumption (kW) / Power Factor
Assuming a power factor of 0.9, the KVA rating required for the 1.5 HP air conditioner would be:
KVA = 1.1 kW / 0.9 ≈ 1.22 KVA
Therefore, a 1.5 HP air conditioner would generally require an inverter with a capacity of around 1.22 KVA. It's worth noting that it's advisable to choose an inverter with a slightly higher capacity than the calculated value to ensure sufficient power supply and avoid overloading the inverter.
