Sihai network: to mention variable frequency air conditioning, we believe that the first reaction is that variable frequency air conditioning is more energy-saving. There is even an advertisement saying that variable frequency air conditioning only consumes one kilowatt hour of electricity a night. So is variable frequency air conditioning really so power saving? How much power does variable frequency air conditioning need in a night? Let's learn how much power is saved by down conversion air conditioning!
How many degrees of electricity does frequency conversion air conditioning have in a 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, one hour's constant temperature can be achieved only once a night, but two degrees of electricity need to be consumed in the first two hours to make the air conditioner reach the set temperature, and two degrees of electricity need to be consumed in the next six to eight hours, so at least three to four degrees of electricity need to be consumed in one night, which is not reliable at all.
How much money does frequency conversion air conditioning save compared with constant frequency air conditioning
If we consider from the perspective of long-term use, the power consumption of variable frequency air conditioning will be less than that of constant frequency air conditioning. Using AC variable frequency air conditioning can save 30% of electricity compared with constant frequency air conditioning, and using DC variable frequency air conditioning can save 50% of energy compared with constant frequency air conditioning. Therefore, in constant frequency air conditioning, DC constant frequency air conditioning can save more electricity than AC variable frequency air conditioning.
I believe you all heard the advertisement that the variable frequency air conditioner only needs one kilowatt hour of electricity in a night. Is this really so energy-saving? How many kilowatts does the variable frequency air conditioner need in a night?
Power saving of variable frequency air conditioning
1. Avoid frequent air conditioning
Do not switch on and off the air conditioner frequently, which is very power consuming, and also has a great loss on the air conditioner compressor. Frequent switching of any electrical appliance will affect the service life of the machine.
2. Open less doors and windows
When the air conditioner is working, the doors and windows should be opened less. If there is sunshine in the room, the curtain should be used to cover the sunshine, and the door should be closed when entering and leaving.
3. Reasonable temperature setting
In summer, it is better to set the temperature between 25 ℃ - 28 ℃. The heating temperature of air conditioner in winter should be set between 20 ℃ and 22 ℃. Winter and summer air conditioning set in the above areas, air conditioning is the most energy-saving, but also beneficial to people's health.
4. Set auto mode
When the indoor temperature reaches the set temperature, it is recommended to set the air speed of the indoor fan to automatic mode. The air conditioner will automatically adjust the fan speed according to the temperature. When the indoor temperature reaches the preset temperature, the fan will automatically turn into low-speed operation.
5. Sleep mode selection at night
During the night rest, the air conditioner can be set to the night sleep mode to achieve the temperature value that is most conducive to human health. The air conditioner will automatically adjust the temperature and save the power consumption at the same time.
6. Clean filter screen of air conditioner regularly
There will be a lot of dust on the filter screen of the air conditioner after the air conditioner has been used for a long time, which will affect the air outlet of the air conditioner and reduce the cooling and heating effect of the air conditioner, which will increase the power consumption of the air conditioner. Therefore, cleaning the filter screen of the air conditioner regularly can also save power.
