1, manufacturing technology of variable frequency compressor.
2. Frequency conversion control chip technology.
The core technologies that Gree has mastered are:
1.GPd DC frequency conversion technology.
2. New high-efficiency centrifuge (remarks are mainly used for large-scale refrigeration equipment, which saves nearly 40% energy compared with the same level)
3. Ultra-low temperature digital multi-connected central air conditioning.
Expand knowledge:
First of all, the four main components of air conditioning are:
1. compressor
2. Capacitors
3. Throttle mechanism
evaporator
Second, the condenser and evaporator are the simplest, and they are basically produced by one air conditioner.
Third, the compressor is the heart of air conditioning, and how an air conditioner works depends on the compressor. Secondly, the accuracy of the throttle mechanism is also very high.
Fourthly, the control system is also an important part of air conditioning. Without a control system, functions such as temperature adjustment, load change and defrosting cannot be realized.
Status:
At present, there are few air-conditioning manufacturers that can independently produce compressors. Many factories are in the assembly stage, just like domestic cars and planes.
