Generally speaking, the larger the horsepower of an air conditioner, the larger the area range of cooling and heating energy it can reach.

One horsepower of refrigeration is approximately 2500 watts, which is usually suitable for use in a room of 12 square meters; Two horses are 5000 watts, suitable for a room of about 25 square meters. At present, the air conditioners in the market include 1p, 1.5P, 2P, 3P, and 5P.

Here is a simple calculation formula, usually:

The cooling capacity of 1 horsepower is approximately 2 kilocalories. Multiplying 2 kilocalories by 1.162, the wattage of 1 horsepower is 2324 watts. And so on:

A 2-horsepower air conditioner has a cooling capacity of approximately 5000W;

The cooling capacity of a 2.5-horsepower air conditioner is approximately 6250W;

The cooling capacity of a 3-horsepower air conditioner is approximately 7500W;

The cooling capacity of a 4-pair conditioner is approximately 10000W.

If the usable area of a small house at home is 10 square meters, and the required cooling capacity per square meter is approximately 115w, then the cooling capacity of the air conditioner is 115w multiplied by 10, which equals 1150w. When purchasing, you can choose an air conditioner with a cooling capacity of 1150w.

Here are some commonly used air conditioning cooling capacities corresponding to the usage area:

The cooling capacity of a one horsepower air conditioner is approximately 2500W, suitable for a room of about 12 square meters;

A 2-horsepower air conditioner has a cooling capacity of approximately 5000W, suitable for rooms of around 25 square meters;

The cooling capacity of a 2.5-horsepower air conditioner is approximately 6250W, suitable for a room of about 40 square meters;

The cooling capacity of a 3-horsepower air conditioner is approximately 7500W, suitable for a room of about 50 square meters;

The cooling capacity of a 4-pair conditioner is approximately 10000W, suitable for a room of about 70 square meters.

Generally speaking, in China, the cooling capacity of air conditioners is calculated based on a cooling capacity of 150-220W per square meter. However, this is also affected by the environment, such as: for those with poor sealing and insulation conditions, the cooling capacity should be appropriately larger, while for those with good sealing and insulation conditions, the cooling capacity can be smaller.

The reason why the outdoor unit of the air conditioner does not operate

1Sudden power outage: If there is a sudden power outage at home and the outdoor unit of the air conditioner does not turn, we need to check whether the indoor unit and outdoor unit are connected normally, because both indoor and outdoor units are connected by AC contactors.

2Condenser malfunction: Generally, when an air conditioner malfunctions, it is likely due to damage to the condenser. The outdoor condenser also has a self-protection system, which will start on its own when it is not regularly cleaned. Therefore, in order to avoid unnecessary trouble, the outdoor unit of the air conditioner should be cleaned regularly.

3Freon leakage: There is a certain limit to the amount of Freon, and too much or too little can affect the normal operation of the air conditioner. At this time, high-pressure protection automatic power on/off will occur.

4Computer board failure: The operation of the outdoor unit is controlled through the computer board, so when the outdoor unit is not running, it may also be due to a computer board failure; Compressor and outdoor unit burnout can also cause the outdoor unit to malfunction.

Solution to Air Conditioning External Unit Not Running

The external dirt and blockage of the evaporator and condenser of the air conditioner can lead to a significant decrease in effectiveness, and even result in non cooling phenomenon. Users should pay attention to regular cleaning and maintenance of air conditioners.

Remove the transformer and measure that there is no resistance in the primary coil. If the secondary resistance is normal, it is obvious that the primary coil of the transformer is damaged. After replacing it with a new transformer and connecting it to the power supply, the power indicator light will light up and the machine will work normally.
