What size air conditioner should you choose? Before facing this question, you may have another question: What does "1 piece" air conditioner stand for? Today we will discuss these two issues in depth.
The "piece" and "tile" on the air conditioner
When we went to the mall and asked the shopping guide: how big is the air conditioner?
You'll probably hear two answers: "It's a 1 piece," or "It's a 26." Both statements are true, but the latter is more standard.
First, a horse: A horse refers to 1 horsepower, and the relationship between the watt is "1 horsepower =735.5 watts". The air conditioner will blur this number and think that 800W is about 1 horse.
When air conditioning is used as a unit, it generally refers to the input power of air conditioning, that is, electricity consumption.
In those days, the technical level of air conditioning was relatively poor, without the concept of efficiency 39bet-xsmb-xổ số tây ninh-xổ số binh phước-xổ số binh dương-xổ số đồng nai. The more you eat, the more you work. So the greater the input power, the greater the output power.
So there is a convention: for every piece of input power, there is 2600W of output power.
But clearly, in today's environment of high and low product efficiency, this argument is outdated.
A more popular term today is "type X": here "X" refers to thousands and hundreds of places. For example, Type 26 refers to the power of 2600W (the actual reference is not clear, the power around 2600W is called type 26).
When the air conditioner is "unit", it refers to the output power (cooling capacity) of the air conditioner. We choose the size of the air conditioner not to see how much it eats, but to see how much work it can do. So the term "type" is more practical and more formal.
In the formal occasion of air conditioning, or formal advertising, almost you can not see the "piece", saying "X type".
Ps: Frequency conversion air conditioning will also say "this is how many pieces". However, in frequency conversion air conditioning, it is pushed back with "2600W output power corresponding to 1 piece of input power". In fact, if you look at the input power, it's not even 800 Watts.
Therefore, in frequency conversion air conditioning, "PI" is redefined as 1 PI = 2600W input power -- this definition can only be applied to frequency conversion air conditioning.
Air conditioning size influencing factors
There are three factors that affect the selection of air conditioning size:
1 room area, the greater the area, the greater the air conditioning should be.
2. Thermal insulation, the western sun, the roof, no external wall insulation layer, will affect the room thermal insulation effect, the choice of air conditioning should also choose a slightly larger.
3. Closed situations, such as bedrooms, are relatively closed. But the living room is often the living room, dining room, corridor together. This kind of room is an open room. Open room, should also choose a larger air conditioning.
4. Heating demand, that is, do you need to rely on air conditioning heating in winter? Air conditioning is less effective at heating than cooling, so if you need it for heating, you'll need to buy a size up.
Choice of air conditioning size
Firstly, according to the room area, a basic data is estimated: 150W cooling capacity per square meter is required.
For example, a room of 15 square meters needs a refrigerating capacity of 150x15=2250W, that is, a type 23 air conditioner. The smallest air conditioning on the market is type 23, 15 square meters below the room, so you should choose type 23.
Consider the other cases mentioned above: insulation/sealing/heating requirements.
For each case, the cooling capacity is increased by 30W/m2.
For example, 15 square meters of the living room, you need 180x15=2700W, that is, 27 type air conditioning - on the market in addition to 26 type is 28 type, no 27 type how to do?
There are a few words in the air conditioning choose and buy, called "buy big do not buy small". So we're going to go up a step and pick the 28.
It IS THE SITTING ROOM OF THIS 15 SQUARE METERS likewise, encountered TOP BUILDING again. How should I DO AGAIN? And the answer is to add two more 30Ws, so your cooling capacity requirement per square meter becomes 210W.
For the living room of 15 square meters on the top floor, the air conditioning size required is 210x15=3150W. Therefore, we are going to buy a model 32 air conditioner.
The same is true when insulation is poor and heating is required. Each time you encounter one, you increase it by 30W.
