Air conditioning is commonly used in summer, and heating can be carried out in winter and treatment can be carried out in summer. Therefore, the selection of air conditioning is also a big problem. It is mainly divided into two types: variable frequency air conditioning and constant frequency air conditioning. Variable frequency air conditioning is mainly used for automatic and stepless speed change. It is mainly used to automatically provide the required cold and heat according to the situation in the room After the non-stop operation to ensure the stability of the ambient temperature.
Variable frequency air conditioning is mainly based on the power supply frequency can not be changed, and at the same time, it can cause the room temperature to turn on and off, and it can make more consumption. The main difference is that the principle of compressor operation is different, and many aspects are also different. Let's briefly introduce what the variable frequency air conditioner is, and the host of the variable frequency air conditioner is automatically stepless When the indoor temperature reaches the expected value, the air conditioning host will operate at a constant speed that can accurately maintain this temperature, so as to achieve "non-stop operation", so as to ensure the stability of the ambient temperature.
What is fixed frequency air conditioning
China's power grid voltage is 220 V, 50 Hz, under this condition, the air conditioning is called fixed frequency air conditioning. Because the power supply frequency can not be changed, the compressor speed of the traditional fixed frequency air conditioner is basically unchanged. The indoor temperature can be adjusted by continuously "turning on and off" the compressor. The room temperature is easy to be changed from cold to hot, and consumes more electric energy.
Difference between frequency conversion and fixed frequency of air conditioning
The biggest difference between frequency conversion and fixed frequency air conditioning is the different application principle of products on compressor. The compressor of frequency conversion products can adjust the temperature appropriately under the condition of long-term operation. If there is no need for a large amount of cold and hot indoor, the air conditioner will operate in a low-frequency state with intelligent constant temperature control, while the constant frequency products need to adjust the cold and hot air conditioning on and off manually.
Frequency conversion air conditioning features energy saving. The frequency conversion air conditioner can adjust the running speed of the heart compressor of the air conditioner at any time through the built-in frequency converter, so as to achieve the reasonable use of energy; because its compressor will not be opened frequently, it will keep the compressor in stable working state, which can make the air conditioner achieve the effect of saving energy by more than 30%. At the same time, it can reduce the noise and prolong the service life of the air conditioner.
High temperature control accuracy. It can control the cooling (heating) capacity of the air conditioner by changing the speed of the compressor. The refrigeration (heat) capacity has a change range, for example, the cooling capacity of 36gw frequency conversion is 360-400w, and the heating capacity is 300-6800w. Therefore, the indoor temperature control can be accurate to ± 1 ℃, making the human body feel very comfortable.
The temperature regulation is fast. When there is a big difference between the room temperature and the set temperature, the inverter air conditioner will work at the maximum power as soon as it is turned on, so that the room temperature will rise or fall to the set temperature rapidly, and the cooling (heating) effect is obvious.
Keep the room temperature constant. Frequency conversion air conditioning adopts frequency conversion compressor, which can automatically adjust the operating frequency of compressor according to the change of room cooling (heating) load. After reaching the set temperature, the inverter air conditioner operates at a lower frequency to avoid the discomfort caused by the drastic change of room temperature. When the load is small and the operation frequency is low, the power consumption of the compressor is small, at the same time, frequent start-up and stop are avoided, so as to save power.
The above is the difference between frequency conversion air conditioning and fixed frequency air conditioning. The main difference is that the principle of compressor operation is different. The compressor of variable frequency air conditioner can operate for a long time, and can adjust the temperature moderately. The air conditioner with constant frequency mainly operates at low frequency. Moreover, it can not be controlled intelligently. Therefore, it is better to choose the compressor in daily life More critical.
