Voltage protector manufacturer tells air conditioner type and function

An air conditioner is an electrical device used to regulate indoor parameters such as temperature, humidity, air cleanliness and air flow rate.

Voltage protector manufacturers talk about types of air conditioners

Split air conditioners

Amperes and wattage:

The power (wattage) and current (amperes) of split air conditioners vary depending on the number of air conditioners, energy efficiency rating, and other factors. Generally speaking, a 1-horsepower (cooling capacity of about 2300-2600W) split air conditioner has a cooling power of about 700-1000W and an operating current of about 3-5A (according to the formula I=P/U, household voltage U=220V); a 1.5-horsepower air conditioner has a cooling power of about 1100-1300W and a current of about 5-6A; a 3-horsepower air conditioner has a cooling power of about 2000-2500W and a current of about 9-11A. The heating power may be higher than the cooling power due to factors such as auxiliary electric heating.

Voltage requirements:

Most split air conditioners are rated at 220V AC, and some high-power commercial or industrial split air conditioners may be 380V AC. In order to prevent voltage fluctuations from damaging the air conditioner, a voltage protector can usually be installed in the air conditioner circuit. When the voltage is too high or too low, the voltage protector can cut off the circuit to protect the air conditioner’s compressor, circuit board, and other key components.

Window air conditioner

Ampere and wattage: Window air conditioners generally have low power, and the common cooling capacity is between 1000 and 2000W. For example, a window air conditioner has a power of about 700-900W and a current of about 3-4A. Because its overall power is not high, it is relatively energy-saving, but the cooling effect is usually limited, and it is suitable for use in small rooms.

Voltage requirements: Window air conditioners’ rated voltage is generally 220V AC, and their voltage stability requirements are also high. Because the compressor and other components are integrated into a relatively compact space, voltage fluctuations may more easily damage their internal components, and installing a voltage protector can also help extend their service life.

Central air conditioners

Amperes and wattage: Central air conditioners have large power and come in various specifications depending on the cooling capacity. Small household central air conditioning systems may have a cooling capacity of 5-10kW, a power of around 2-5kW, and a current of about 9-23A (calculated at 220V AC); large commercial central air conditioning systems can have a cooling capacity of tens or even hundreds of kilowatts, and the corresponding power and current are also very large. For example, a central air conditioner with a cooling capacity of 100kW may have a power of around 30-40kW and a current of 136-182A (calculated at 380V AC).

Voltage requirements: The rated voltage of a central air conditioner can be 220V AC or 380V AC depending on the power size. Due to its high installation cost and complex equipment, the requirements for voltage stability are more stringent. Voltage fluctuations may not only damage the equipment itself but also affect the operation and service life of the entire air conditioning system. Therefore, it is very necessary to install professional voltage protectors, which usually have more complex functions such as multi-level protection, data logging, etc.

Wall-mounted air conditioners

Wall-mounted air conditioners are split air conditioners. Its indoor unit is hung on the wall, and the outdoor unit is installed on the exterior wall of the building or on the ground outdoors. Its power and current range are similar to split air conditioners and also vary according to the horsepower and energy efficiency level.

For example, the cooling power of a common 1.5-horsepower wall-mounted air conditioner is around 1100-1300W, the operating current is about 5-6A, and the rated voltage is generally 220V AC. Like other split air conditioners, it can also be equipped with a voltage protector to ensure its stable operation.
