The functionality of any climate technology is determined by several parameters, one of them is the power consumption of the air conditioner. The units of power for the air conditioner are W and BTU \ h. This indicator affects the size of electricity bills, as well as the way the device is connected to the power supply: directly, through its own bag or simply by plugging in a power outlet.
Power consumption or cooling power?
These are two completely different indicators that mislead many buyers.
The power consumption of the air conditioner in kW is 3 times lower than the cooling power. So, if 3 kilowatts is indicated on the case, then it consumes an air conditioner of approximately 900 watts. Which is much less than a microwave or hairdryer.
Therefore, with the cooling capacity of the air conditioner in kW 2 - 4, you can fearlessly power it from a conventional power outlet.
By the way, the power consumption of the air conditioner, as a rule, is measured in watts, since it rarely reaches even 1 kilowatt in household models.
Power consumption
The power consumption indicator of the air conditioner is calculated, according to international standards, in laboratory conditions at a set outdoor temperature of +35 and inside the room +27 degrees Celsius.
Interestingly, as the temperature changes, the average cooling power changes. So, at a temperature outside of -15 degrees, it can fall by 50-60%, while the power consumption of the air conditioner remains unchanged.
In connection with the power consumption of the air conditioner in kW, many consumers have a question about how much electricity the air conditioner consumes per year? For this, the total amount of electricity used is calculated. This indicator is measured in kWh / year or kWh \ annum. Multiplying it by the price of one kilowatt hour, we get the amount that will cost approximately the operation of the device per year. The total amount of electricity consumed is also calculated in the laboratory. At the same time, the recommended indoor temperature is +26.5 degrees Celsius.
If the consumer is used to cooling the air to +24, his air conditioner will “eat” much more electricity. The indicator directly depends on the kW power of the air conditioner.
Power consumption and method of connecting the air conditioner
In modern buildings, the electrical wiring can withstand up to 16A of current, in old ones - no more than 10A. In order to prevent overload, the current consumed should be one third less than the maximum allowed.
That is, if 1500 - 2400 W of air conditioning power for consumption (cooling in this case is 5 - 9 kW), its operating current is from 7 to 11 Amps. You can not pull a special cable for it, but only if other powerful electrical appliances are not connected to this cable.
