Friends who have studied physics should know that electricity consumption and electrical power are closely related. Using fan coil power / kWh can calculate the amount of fan coil electricity consumption per hour, such as 4500W / 1 hour = 0.45 kWh, so knowing the fan coil power, and then according to the daily use time, you can calculate the daily power consumption of the fan coil, and then add the power consumption of all the fan coils in the room It is the daily electricity consumption of the central air conditioner in the room.
       Therefore, if you want to know the power consumption of the fan coil, you must first figure out the motor power of the fan coil. On this point, the fan coil manufacturer will have the corresponding fan coil technical parameters, which includes the fan coil Motor power, air volume, cooling capacity and other technical parameters are convenient for users to choose fan coils.
       If the fan coil power is unclear, we can also calculate it in reverse, rated current = power / (supply voltage * power factor), if it is 380V, then divided by 1.732, if you do not know the power factor, the general motor is about 0.85, It is recommended to count at 0.85.
       Usually the power of the fan coil is about several hundred watts, which is still very small compared to the power, so the power consumption is not very large, not much worse than the lighting lamp, so many friends say that the power consumption of the fan coil is high, it should be Under the premise that multiple fan coils work at the same time in high-end occasions 24 hours a day, the power consumption of normal household fan coils will not be very high, because they all need to work, so there is not much at home every day. And basically there will be no common use of all fan coils. Horizontal concealed fan coil power is divided into input power and output power:

       The power consumption of the central air-conditioning fan coil motor refers to the input power, which also refers to the power absorbed by the device. The input power is equal to the product of the input voltage and the input current.

       Input power usually refers to input power, and output power = rated power * fan efficiency

       Therefore, the power of the fan coil is an important part of the power consumption of the fan coil, and the power directly determines the amount of power consumption of the fan coil. The power consumption of a small fan coil will naturally be less.
