The functionality of any HVAC equipment is determined by several parameters, one of which is the power consumption of the air conditioner. The units for measuring the power of 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 inserting a plug into an outlet.
Power consumption or cooling power?
These are two completely different metrics that mislead many buyers.
Therefore, with the cooling capacity of the air conditioner in kW 2 - 4, you can fearlessly power it from a conventional electrical outlet.
By the way, the power consumption of an air conditioner, as a rule, is measured in watts, since it rarely even reaches 1 kilowatt in household models.
Power consumption
The indicator of the power consumption of the air conditioner is calculated, according to international standards, in laboratory conditions at a set temperature outside +35 and inside the room +27 degrees Celsius.
Interestingly, as the temperature changes, the average cooling capacity changes. So, at an outdoor temperature of -15 degrees, it can fall by 50 - 60%, while the power consumption of the air conditioner remains unchanged.
In connection with the consumed power of the air conditioner in kW, many consumers have a question about how much electricity does the air conditioner consume 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, which will approximately cost the operation of the device for a year. The total amount of consumed electricity is also calculated in laboratory conditions. At the same time, the recommended indoor temperature is +26.5 degrees Celsius.
If the consumer is accustomed 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 connection method of the air conditioner
In houses of modern construction, electrical wiring can withstand up to 16A of current, in old ones - no more than 10A. To prevent overload, the current consumption must be one third less than the maximum allowed.
That is, if the power of the air conditioner is 1500 - 2400 W for consumption (cooling in this case is 5 - 9 kW), its operating current is from 7 to 11 Amperes. For him, you do not need to pull a special cable, but only if other powerful electrical appliances are not connected to this cable.
