In the air-conditioning industry, the original meaning of 1 air conditioner is a cold air conditioner made of 735W electricity.
1 horse = 1 horsepower =735W, horse originally does not mean refrigeration capacity. Usually, the number of air conditioners is based on the power consumption of air conditioners to estimate the cooling capacity of air conditioners. Generally, the refrigeration capacity of 1 pcs is equal to 2500w (i.e. 25 models), and that of 1.5 pcs is equal to about 3500 pcs (i.e. 35 models).
Extended data:
The ideal energy efficiency ratio of air conditioners is generally around 3.0-3.6, that is, the ratio of refrigeration capacity to input power. Therefore, the refrigeration capacity of 1 air conditioner is about 2500W W, but in the air conditioning industry, air conditioners with refrigeration capacity of 2300 to 2700W can all be called 1 machine.
Watt was named after james watt, a British scientist, who made great contributions to the development of steam engines. This unit name was first adopted by the second meeting of the British Association for the Advancement of Science in 1889.
1960, the international metrology congress 1 1 adopted watt as the unit of power in the international system of units. People often use unit of power times time unit to express energy. For example, 1 kwh is the energy consumed by an energy-consuming device with a power of 1 kw in 1 hour, which is equal to 3.6* 1000000 joules.
