Different from the traditional cooling methods for external units: installing water pumps, watering, and adding awnings to external units, these methods cannot fundamentally solve the problem. Installing water pumps requires continuous investment in water and electricity costs. Watering can only solve a temporary emergency. There is a risk of falling off in the later stage. The Valley Wind solution sprays Valley Wind No. 1 synthetic material on the external condenser. It is invested in one time and does not affect the appearance and has no safety risks in later use.

Compressor and motor are the core components of air conditioners, and their power consumption accounts for more than 80% of the air conditioner's electricity consumption. The high temperature of the compressor and poor heat dissipation will lead to increased power consumption while the compressor continues to work at high temperatures. Air conditioning accessories are more easily damaged, resulting in short air conditioning life and high maintenance costs. The valley wind annular heat sink is a heat sink made of various materials mainly composed of rhombic crystals in the semiconductor field after thousands of arrangement and combination tests. By installing this device, combined with condenser surface spray treatment and intelligent control box, the compressor temperature can be continuously reduced by 10-15 degrees, and the compressor can be maintained in the optimal temperature range, thereby improving energy efficiency and saving electricity by more than 30%.

During the research and development and design of Valley Wind No. 1 synthetic spraying material, considering that the external unit of the air conditioner cannot be cleaned all year round, resulting in serious health problems, it has become a breeding ground for bacteria. Therefore, nano-silver, a protective material in the aerospace field, is added to the material. There are many tiny "needle tip structures" on its surface. These structures can penetrate the cell walls and membranes of microorganisms, enter the interior of cells, and destroy the cell metabolic process, thereby achieving the effect of killing bacteria and inhibiting bacterial reproduction and regeneration. Spray the air conditioning condenser to sterilize and disinfect it when air intake is outdoors. Healthy fresh air is blown indoors to reduce air conditioning diseases. At the same time, nano-silver has a high thermal radiation rate, which can improve heat dissipation and cooling while taking into account health.

The outlet temperature of indoor units drops by 4-6 degrees, which increases the cooling capacity per unit time and improves the cooling efficiency of air conditioning. In the same environment, the cooling time is shortened, the compressor usage time is reduced, and the power saving rate is more than 25-30%(more than 40% of inverter air conditioners). Reduce the exhaust temperature at outdoor unit outlets, reduce heat emissions and alleviate the greenhouse effect for more than 5 billion split air conditioners around the world.
