Sihai network: in summer, more users will choose variable frequency air conditioner when they buy air conditioner. Variable frequency air conditioning is more intelligent and energy-saving than constant frequency air conditioning. The frequency of variable frequency air conditioning is always changing, so is the power consumption of variable frequency air conditioning? How does the variable frequency air conditioner work and how to calculate its power consumption? Let's have a look.
How to calculate the power consumption of variable frequency air conditioning
Because the frequency of variable frequency air conditioning compressor is variable, it is difficult to calculate the power consumption, but we can calculate the power consumption of variable frequency air conditioning in the average time. Generally, the nameplate of variable frequency air conditioner will clearly indicate the power, cooling capacity, etc. However, it is not easy to calculate according to the maximum and minimum set power because the time-space adjustment will run at the maximum frequency at the beginning of operation, and then work at a smaller frequency when the set temperature is reached.
We can use the average calculation method. The power written on the air conditioner refers to the average power used by the air conditioner in a year. As long as we are not going to be very precise, we can install the average power to calculate. As shown in the figure below, the average cooling power of the air conditioner is 1060w. If the air conditioner is used for 10 hours, the power consumption is 10.6kw/h, which is what we call 10.6 kwh.
The frequency of variable frequency air conditioning is always changing. How can we calculate its power consumption? Let's know.
How much electricity does the inverter air conditioner use in one night
How much electricity a variable frequency air conditioner uses depends on the size of the room, the temperature of the room, the set temperature, and the number of people. If it's a 1-HP variable-frequency air conditioner, it needs only one degree of electricity for one hour to reach constant temperature, but it needs more than two degrees of electricity for two hours before starting to make the air conditioner reach the set temperature, so it needs at least 3-4 degrees of electricity for eight hours at night.
How to make inverter air conditioner more power saving
1. Do not turn on and off frequently
The working state of the variable frequency air conditioner is to keep low power operation. At this time, the air conditioner is the most energy-saving state. Don't turn off the air conditioner specially to save power. When the room is hot, it will consume more power. Frequency conversion air conditioning is because of reducing the number of starts and stops, so it has more power saving effect than ordinary air conditioning, so do not always switch on and off the frequency. When the temperature of variable frequency air conditioner is suitable, the longer the start-up time is, the more power is saved. The shorter the start-up time is, the more power is consumed. The longer the time is, the more obvious the power saving effect is.
2. Control the temperature well
The air conditioner should not adjust the temperature frequently. It is OK to adjust the air conditioner once. It is better to adjust it to the temperature suitable for human body, not too high or too low. For example, when cooling, set the temperature to be 1 ℃ higher, and when heating, set the temperature to be 2 ℃ lower, so that the air conditioner can save more than 10% of the electricity.
3. Indoor insulation
When cooling in summer, it is better to draw curtains indoors to avoid direct sunlight, which will lead to indoor temperature rise, ensure smooth ventilation at the air outlet of the air conditioner, install the air conditioner in a position where there is no furniture shelter, and do a good job in the ventilation environment of the air conditioner, all of which are conducive to the rapid adjustment of indoor temperature to achieve the purpose of power saving. It is better to set the automatic mode when the variable frequency air conditioner is started, so that the air conditioner can adjust automatically according to the indoor temperature.
4. Regular air conditioning cleaning
The filter screen and heat sink of the air conditioner should be cleaned frequently to maintain good cooling and heating effect, because after the air conditioner is used for a long time, there will be a lot of dirt and dust inside the heat exchanger, which will cause the heat sink to stick, so that the air volume will be reduced, the heat exchange efficiency will be reduced, and the power consumption will naturally increase.
