Thank you

1. This is not painted by AI;
2. This is the conceptual scheme of the original air duct structure we put forward three years ago;
3. Even if you really do air conditioning, it doesn't mean you are a professional. Even if you have been in the industry for more than ten years, you don't necessarily have the tone of your voice. I suggest you don't make any suggestions.

If it is the original air duct, there are three kinds of mainstream air duct in the current market.
1. The single centrifugal fan blade of the old-fashioned square cabinet cannot do the current national standard level 1 energy efficiency.
2. The cross-flow fan blades for mainstream round cabinets are of pure cylindrical foundation and are gradually turning to the front and rear circles (Midea/Haier)
3. Double flow and double air outlet (COLMO/casarte of the United States) or single flow and double air outlet (Gree/Panasonic/Hisense/Xiaomi). Two air outlets are designed to deal with some problems with dead corners of air supply. The earliest plan was LG of South Korea, but it is not done now.
The non-mainstream air duct in China also includes Gree's double centrifugal compasses (Gree Rose), which is a very cow-force air duct system. It can go up and down on the cabinet machine, but it is defeated by the appearance of the first generation. There is also Midea's combined double-fan air duct, which is estimated to avoid Gree's double-centrifugal air supply design and cannot be used for downwind.
In the domestic air conditioning industry, Gree and Midea basically have independent fluid teams to be responsible for the research and development of air ducts for air conditioning. Second-line companies basically buy their machines, take air ducts and blades to plastic, and then use them directly after a slight change. The engineers from Gree Mei in our company are basically focused on a specific type for a long time, and they know very little about new products from the outside world, even LG and Samsung.
If it is to make original air duct, I am very curious about how the basic selection of air duct is determined, and if the current national standard energy efficiency is to be met, the air supply volume of the internal machine should be at least 1300 m/h, which means that the machine should have enough large area of air inlet and outlet.

Otherwise, the small area of air inlet and outlet will lead to various problems such as noise and condensation of air outlets. I have always been very opposed to pure design companies getting involved in air conditioning design. I took over three design companies and came up to do the design without understanding the underlying logic of the product. the scheme made was not right for the horse's mouth.

I can see that brothers are really in the industry. As you said, there are several forms of air duct structure for market products. Most manufacturers repair or change a panel to a shell on this basis. I don't know what form the design company you contacted before is, but until now the design can only be made of pure appearance, then we are ready to eat Xiang. although we can't say how professional it is, we can understand the basic structure and principle clearly. we proposed the change of air duct form in this project. according to our idea, the enterprise has tested and adjusted the functional hand board to verify all kinds of problems you mentioned, before and after more than a year to do the appearance design. Structure Principle Performance Parameters We may not be as professional as you, but what kind of product can a product produce if everyone is stuck in a mindset and goes around in three structure samples? Although this project did not land due to market reasons, I sincerely admire the customers who can make their own air duct innovation. You can question it based on your cognition, but I can't bring out the structural drawings and pull them with you. Welcome to our company for research and discussion, which may make your impression on the design company a little different.

It is quite difficult to use AI to output such complicated category design, at least I don't know how to describe the principle of air duct.

Thank you
