How much area can I use with 1 HP air conditioner? Many people don't know how to choose the number of horsepower of the air conditioner? Today's article will solve the problem of how to choose the number of air conditioners? and the problem of power consumption of air conditioners.
Nowadays, there are very few air conditioners with 1 horse and 1 horse, and most of them are large 1 horse and 1.5 horse air conditioners on the market, because the principle of buying air conditioners is to buy big and not small. Because of the use in the same environment, the power consumption will not be much different, and the experience of using a larger air conditioner will be much better.
Let's take a large 1 hp air conditioner as an example.
01
How much area does a large 1 HP air conditioner use?
The current number of air conditioners is defined by the cooling capacity, with an output of 2300W cooling capacity as 1 horse, and the large 1 horsepower air conditioner on the market is the KFR-26GW model, that is, an air conditioner with an output cooling capacity of 2600W.
According to the calculation of 200W cooling capacity per square meter, a large air conditioner can use a 13 square meter room. Of course, this is only a theoretical value, not an absolute number, and it is related to the following factors:
1. Air conditioning is used in a space, and air conditioning is in a space, which is actually more scientific to use space. In other words, the usable area of a large 1 HP air conditioner is also related to the floor height of the house.
When we say 13 square meters, we are just calculating the height of an ordinary house, such as 2.8-3 meters, and the space of a house with an area of 13 square meters is 39 cubic meters. If the floor height of the house is 5 meters, then the area that can be used by the air conditioner of 1 hp is only 39/5 = 7.8 square meters.
2. If your house is in the west, or on the top floor, and it is usually hot, then when choosing an air conditioner, it is recommended to go directly to the larger one. If you are less than 15 square meters, you can directly choose a 1.5 hp air conditioner, and if you are more than 15 square meters, you should consider a 2 hp machine. Otherwise, the walls are hot, and the air conditioner is not cool for a long time.
I used to live in a west-drying room, and it usually took 2 hours to turn on the air conditioner before the temperature of the room dropped overall. If you want to cool down in the early stage, you can only let the cold air of the air conditioner blow directly.
3. The choice of the number of air conditioners is also related to personal physique and usage habits. After all, air conditioners are for people, and different people have different requirements for temperature when they use them.
People with cold bodies do not have such high requirements for air conditioning and refrigeration, and the temperature set when the air conditioner is usually turned on is also high, such as 28 degrees. In this case, the room is 15-17 square meters, and it is enough to use a large 1 hp air conditioner.
People with body heat have high requirements for air conditioning and refrigeration, and you can appropriately increase the requirements when choosing air conditioning, such as 1 horse for less than 10 square meters, and 1.5 horses for more than 10 square meters. Or rooms under 10 square meters can also be directly 1.5 horses.
I have a colleague in my company, who belongs to the body heating person, the office uses a 3 hp cabinet machine, open 26 degrees, I feel a little cold, but he still needs to add a fan.

How many kilowatts is 1 HP air conditioner power? How many kilowatt-hours of electricity per hour?
For the same 1 hp air conditioner, the power of the air conditioner is different for different energy efficiency levels. In other words, the air conditioner with the same amount of cooling can be generated, and the power consumption of the first-class energy efficiency is less. How much power is it? Let's illustrate with the following parameter label of a first-class energy efficiency air conditioner with 1 HP:
In the refrigeration mode under standard operating conditions, the input power is 555W, that is, about 1 kWh of electricity in 2 hours. This is when the indoor temperature does not reach the set temperature, the power consumed by the air conditioner for refrigeration.
The minimum power of the air conditioner quality is 70W, that is to say, after the temperature reaches the set temperature, if the insulation effect of the room is good, the air conditioner runs at a minimum power of 70W, and can maintain the set temperature, the actual power consumption of the air conditioner is only 70W, of course, this is only a theoretical value.
In the actual use of the air conditioner, the power of refrigeration in the first half hour is generally fully on, and after reaching the set temperature, it is basically running at about 100W to maintain the set temperature.
Air conditioning, of course
The amount of electricity consumption is mainly related to the loss of cooling capacity (heat) in the room.
1. For example, if the insulation effect of the walls of the room is good? Is there air leakage in the windows of the room, the door footing? will affect the loss of air conditioning. The more air is lost, the more cold air needs to be replenished by the air conditioner, and the more electricity the air conditioner consumes.
2. The temperature difference between indoor and outdoor. The greater the temperature difference between indoor and outdoor, the more cooling will be lost, and the more power will be consumed by the air conditioner.
For example, if the outdoor air conditioner is 32 degrees Celsius, and the indoor air conditioner is turned on at 28 degrees, the power consumption is different from that of 26 degrees.
The power consumption of the air conditioner is also different when the indoor is 26 degrees Celsius, the outdoor is 32 degrees Celsius and the outdoor is 36 degrees.
Therefore, the power consumption of air conditioners is closely related to the environment of the house and personal usage habits, and cannot be generalized.

What is the difference between a large 1 hp and a 1.5 hp air conditioner?
The cooling capacity of the large 1 hp air conditioner is 2600W, also known as the KFR-26GW model, and the cooling capacity of the 1.5 hp air conditioner is 3500W, also known as the KFR-35GW model. It's just that the power is different.
In fact, most of the large 1 hp air conditioners and 1.5 hp air conditioners are the same size, just the same series of air conditioners with 1 hp and 1.5 hp large air conditioners, the filter is exactly the same.
The 1.5 hp air conditioner is a standard machine, and the larger 1 hp air conditioner is the reduced version of the 1.5 hp air conditioner, and the 1.5 hp air conditioner is actually only about 200 yuan more expensive than the larger 1 hp.
Is a 1.5 hp air conditioner more power-hungry than a 1 hp one?
In fact, whether the air conditioner consumes electricity or not depends mainly on the loss of cooling capacity. In practice, the 1.5 hp air conditioner and the 1 hp air conditioner are maintained at 100W power after reaching the set temperature. The actual power consumption is about the same. The 1.5 hp can reach the set temperature more quickly.
In the following two extreme cases, a 1.5 hp air conditioner consumes more electricity than a 1 HP air conditioner:
1. The thermal insulation effect of the room is quite good, and after reaching the set temperature, only the lowest operating power is needed to maintain the set temperature.
2. The air conditioner has been running at full speed if the set temperature has not been reached, such as opening the window and opening the air conditioner.
