To the question: "what capacity to choose an air conditioner?" Only a specialist should answer. Properly selected power ensures optimal operation without overloads and the start of unnecessary cycles. Our materials provide several options for a more or less accurate power calculation. They are suitable for an approximate "estimate", but not for the acquisition of HVAC equipment in a large store or office. What is the danger of buying an air conditioner of high power or low power?
High power air conditioners
“I'll take a large capacity air conditioner. He will certainly cope with the cooling of any area. ” This is a very common mistake among buyers who are not constrained by funds. There are several disadvantages of acquiring an air conditioner with a power reserve:
- You knowingly overpay. The more powerful the equipment, the higher its price. This is sometimes used by unscrupulous sellers, persuading buyers to buy equipment "abruptly";
- The air conditioner will not be able to keep the temperature at a predetermined value, since it will need to constantly turn off and on. The likelihood of early wear is greatly increased. This rule does not apply to inverter systems;
- The inverter-controlled air conditioner cannot stop at all. It only slows down. The minimum power is, depending on the model, 0.5 - 1 kilowatt. That is, the owners will pay extra money, and the equipment will work in vain;
- An excessively strong cold air stream will create an uncomfortable atmosphere and can cause colds.
About how much power to choose an air conditioner, read in our articles on calculating the power of an air conditioner.
Low power air conditioner
Customers who want to save on the purchase of HVAC equipment are inclined to this choice. And they are wrong.
How much power do you need air conditioning? - Calculate using a special formula. If you buy a low-power air conditioner, you won’t get any problems.
Here, the compressor is primarily affected. On hot days, it will work almost non-stop. Overheating and breakdown are provided.
And the owners themselves will feel the lack of life-giving coolness from a low-power air conditioner. It will make itself felt in the summer, in the heat.
Thinking about what kind of power an air conditioner needs, it should be borne in mind that an error of up to 15% is allowed between the indication obtained in the calculations and indicated in the technical specifications of the device.
