If the air conditioner is used for a long time at home, then frequency conversion is indeed power-saving.
Because the power frequency of the air conditioner is fixed at 50Hz, the speed of the compressor is fixed, that is, the circulation of refrigerant (freon) called "air conditioner blood" is constant. The greater the circulation of refrigerant in a certain period of time, the higher the output power of the air conditioner. In other words, the speed of the compressor determines the output power of the air conditioner.
The variable frequency air conditioner is an air conditioner using variable frequency compressor and fuzzy control technology, which can adjust the cooling speed according to the change of indoor temperature. It has the characteristics of low noise and low energy consumption. In a room of 15 square meters, the speed of variable frequency air conditioning is 6-10 minutes faster than that of constant frequency temperature regulation. After reaching the set temperature, the variable frequency air conditioner can operate at a low speed with only 10% of the power of the constant frequency air conditioner to adjust the small temperature loss and maintain the constant temperature state. The test shows that compared with constant frequency air conditioners, the noise of variable frequency air conditioners is 5-6 decibels lower and the service life is 5-8 years longer, which is the future development direction of the air conditioning market.
Advantages: The variable frequency air conditioner adopts the organic combination of variable frequency power supply, variable frequency compressor, electronic expansion valve and microcomputer technology, which further improves the performance of the air conditioner. The room temperature fluctuation is small during use, and the comfort is better. It is not sensitive to the fluctuation of power supply voltage. After the compressor is started, it generally does not stop, and the cooling capacity changes in the range of 35% to 117%, which avoids the frequent start and stop of the ordinary air conditioner, and extends the service life of the compressor, At the same time, it has the characteristics of high efficiency and energy saving.
Disadvantages: The price is relatively expensive, which is about 1/3~1/4 higher than that of ordinary air conditioners. At the same time, due to the complexity of the control system and frequency conversion system of frequency conversion air conditioners, the requirements for components are high. Compared with ordinary air conditioners, the failure rate of frequency conversion air conditioners is high. Moreover, due to the use of frequency conversion technology, harmonic pollution will occur at the same time of frequency conversion.
Tips for using variable frequency air conditioner
The P number of the selected variable frequency air conditioner shall be determined according to the area of the room. Generally, 1P unit is used in a room of no more than 14 square meters. Try to avoid using in the case of excessive area. Do not set the temperature too low. It is better to set it in the "automatic" gear when using, which is both comfortable and energy-saving.
