The difference between variable frequency air conditioning and fixed frequency air conditioning Popularize air conditioning knowledge.

It's spring now, and I still can't feel the pain of the hot weather. In summer, in the face of the helpless high temperature, air conditioning has become an essential weapon for us to cool off the heat! But when buying air conditioners, frequency conversion and fixed frequency have become a difficult problem in front of us! What is frequency conversion? What is a fixed frequency? What's the difference between variable frequency air conditioner and fixed frequency air conditioner? Knowing the air conditioning knowledge I introduced below, frequency conversion and fixed frequency will never be difficult for you!

1. What is inverter air conditioning?

Frequency conversion air conditioner: Frequency conversion air conditioner can adjust the running speed of compressor at any time through the built-in frequency converter, so as to make rational use of energy. After the inverter air conditioner is turned on, it will run at high frequency to reach the set temperature and immediately cool. When the room temperature reaches the set temperature, turn to low-frequency operation, gently blow air, and the sound will be very small. Keep the room quiet and the temperature stable. It is precisely because the compressor of variable frequency air conditioner will not start frequently that the compressor always keeps a stable working state, which can reduce the noise and prolong the service life of the compressor.

Second, what is a fixed frequency air conditioner?

Fixed-frequency air conditioner: Compared with variable-frequency air conditioner, fixed-frequency air conditioner needs more human actions to adjust, and the compressor of variable-frequency air conditioner is automatic. After the fixed frequency air conditioner is turned on, the frequency is fixed and the cooling speed is slow. Stop running before the temperature reaches the set temperature, and the air conditioner itself will not automatically adjust the cooling or heating speed. Users must manually adjust or turn off the air conditioner to achieve the purpose of adjusting the operation of the air conditioner.

Third, the difference between them.

1, cooling and heating capacity

The inverter air conditioner compressor runs at high speed like a gyro. The stronger the running capacity, the faster the indoor temperature changes, and the stronger the rapid cooling and heating capacity. Especially in hot summer or cold winter, rapid cooling and heating are very necessary. The refrigeration capacity of fixed frequency air conditioner is good in summer, but not enough in winter.

2, energy saving

Constant-frequency air conditioner has been heating at rated high power during operation, and the air conditioner stops after the room temperature rises to the set temperature of the air conditioner; When the room temperature drops to the set temperature of the air conditioner, the air conditioner is started again, and so on. Inverter air conditioners are not started as frequently as fixed frequency, and will not generate instantaneous large current again and again; At the same time, the lower the operating frequency of DC compressor, the higher the energy efficiency ratio of air conditioner.

Step 3 be comfortable

Because the running speed of the constant frequency compressor is fixed, the constant frequency air conditioner starts and stops, and the room temperature fluctuates up and down, which brings discomfort to people. The inverter air conditioner works continuously, the indoor temperature is constant, and there is no cold and hot discomfort. Frequency conversion air conditioner has high comfort.

The above is the introduction of the difference between inverter air conditioner and fixed frequency air conditioner, and I hope it will help everyone!
