Background and technological evolution analysis of air jet technology
Air jet technology is a technology based on the principle of fluid injection. The air around the outlet is injected through a ring-shaped air outlet device, thereby increasing the air volume and outlet air temperature and improving comfort. The application of this technology in air conditioners can be traced back to early fluid mechanics research. In recent years, with the improvement of energy efficiency requirements, air injection technology has gradually become an important component of high-performance air conditioners.
Implementation suggestions
- Manufacturers are advised to fully consider the application potential of air injection technology when designing new models
- During the product testing phase, the air volume, air supply distance and air outlet temperature should be tested strictly in accordance with standard requirements
- Users should pay attention to the energy efficiency ratio and actual performance of the product when purchasing air injection air conditioners
