How much electricity is the difference between inverter and fixed frequency air conditioner overnigh

In the case of confined spaces, the difference in energy consumption is minimal.

There is basically not much difference in power consumption. Frequency conversion will save a little bit of the world, but don't expect a difference of a few kilowatt-hours of electricity, just one or two degrees. The focus is on the temperature of the inverter is more stable and more comfortable.

There are slight differences in air conditioners of different brands and models. Taking 1 HP air conditioner as an example, 1Hz reaches a constant temperature state for 24 hours, but the power consumption in the first two hours of shutdown is large, reaching more than 2 degrees, so it must consume 3-4 degrees of electricity when the inverter air conditioner is turned on for 8 hours a night.

The power consumption and maximum power of the inverter air conditioner are closed, and the greater the power of the air conditioner, the more power will be consumed. In addition, it is also related to the size of the room, whether the room is blocked from the sun, and the thermal insulation effect of the house. All in all, there are many constraints that must be considered comprehensively.

The difference is about 3 degrees.

If the frequency of the inverter compressor is 60 Hz, the energy efficiency ratio.

If it is 3, then after reaching the frequency reduction condition, the energy efficiency ratio will be greater than 3, which will save electricity, and when it is greater than 60 Hz, the energy efficiency ratio will be less than 3, and the electricity will be consumed. As for how much electricity can be saved in a day, it depends on the thermal insulation effect of the use environment.

The higher the efficiency of the air conditioner, the more power saving, and the larger the air conditioner condenser.

Area can improve efficiency. However, it has increased the cost of production.

The efficiency of the inverter air conditioner is not high when it is first turned on, and the power of the air conditioner decreases after approaching the set temperature. Relatively speaking, the area of the condenser is equal to the increase, and the efficiency is very high, so it saves electricity.

Air conditioner size. According to the national standard, the size of the room air conditioner is based on the cooling capacity.

Parameter annotations. For example, a model of KFR-22GW air conditioner, in which the number "22" means that the cooling capacity of this air conditioner is 2200W, which can be referred to as "22 type". However, many people do not call it that, but call it as many "horses", but in fact, it is completely wrong to call them "horses".

"Horse" is a unit of power.

1 hp (horsepower) = 735W (watts), in the past, in Japan, the oral name was called 1 HP air conditioner with an input power of 735W, and an air conditioner with an input power of 1470W was called a 2 HP air conditioner. However, due to the fact that the input power of the air conditioner is not necessarily just the whole horse, such as 1400W or 1600W, it is called 2 horses small and 2 horses respectively; Between 1 horse and 2 horses, it is called a horse, and so on.

The difference between inverter and fixed frequency is a few kilowatt-hours a night, and there will be differences between different brands and models of air conditioners.

Take 1 HP air conditioner as an example, fixed frequency air conditioner.

If the set temperature is above 26 degrees, then the compressor can automatically stop when the set temperature is reached, and then start automatically when the indoor temperature rises, and the power consumption is expected to be about 1 kWh in 1 hour. It takes about 8 hours a night and consumes about 8 kilowatt-hours of electricity. And the change of staring chain frequency air conditioning.

It takes 3 to 4 kilowatt-hours of electricity a night.

The difference between air conditioner inverter and fixed frequency

a. The working principle of DC inverter air conditioner is to convert the 50Hz power frequency AC power supply into DC power supply and send it to the main circuit of the power module, which is also affected by the microcomputer.

The difference is that the module outputs DC and Sun Yuan with variable voltage, and the compressor uses a DC motor.

Therefore, DC inverter air conditioner can also be called full DC variable speed air conditioner. DC inverter air conditioners do not have an inverter link, which is more energy-efficient than AC inverter in this regard.

b. The working principle of AC inverter air conditioner is: inverter technology is a technology that changes the frequency of the power supply through the inverter, thereby changing the speed of the compressor (see Figure 1 Block diagram of the inverter inverter of inverter). The AC to DC conversion is carried out first through the inverter, and then the DC to AC conversion is carried out through the inverter, so as to control the speed of the AC motor.

The control of the inverter is to transmit the indoor temperature information to the microcomputer through the sensor, and output a waveform with a certain frequency change to control the frequency of the inverter. When the indoor temperature is rapidly cooled or heated rapidly, the indoor air conditioning load increases, and the compressor speeds up and the cooling capacity increases.

Proportionally increased, on the contrary, when the indoor air conditioning load decreases, the compressor runs normally or slows down.

The actual difference is not very large, when the external ambient temperature is very high, the difference is about one kilowatt-hour; When the external ambient temperature is not high, the phase difference temperature will be slightly higher. The main reason is that the noise of inverter air conditioning is small, and the comfort is better than that of fixed frequency.
