Ordinary air purifiers usually place the fan at the front end of the filter or the middle end of the filter (upper and lower piles with filtering wind channels) to reduce noise. It can be said that ALLERAIR has achieved the perfect combination of the core elements of the purifier: high -performance filter material, absolute sealing and strong fan. Allerair's fan efficiency can reach more than 90%.

It was learned from Nankai University that the team of Professor Chen Yongsheng of the school made a breakthrough in the research of organic solar cells, which made the conversion efficiency of organic solar cells reach 17.3%.

When night falls, every corner of the courtyard is waiting to be awakened by light. With their unique charm, solar lights have become the stars of modern garden lighting.Solar lights are not only environmentally friendly and economical, but also give the courtyard unlimited possibilities in the interplay of light and shadow.Solar lights, which absorb sunlight and store energy during the day, automatically light up at night.This design not only reduces energy consumption, but also reduces reliance on traditional power sources.

Recently, Australia will try to use solar and wind energy to produce hydrogen through electrolysis, and then use hydrogen for long-term energy storage in Sydney's natural gas energy.

As an environmentally friendly, energy-saving lighting equipment, solar lights have become increasingly popular among consumers in the market in recent years. However, in the face of a wide range of solar light products on the market, how should consumers choose the right solar light ? 1、When choosing solar lights, consumers need to understand the basic principles of solar lights in order to better choose the right product for them. 2、Consider the use of solar lights in the scene, use time, lighting range, waterproof level and other factors to meet the actual use needs. 3、The most important thing is to focus on the quality and performance of the solar lights. Landsign has been specializing in solar lights for 18 years and has a wide range of solar lights and can give comprehensive advice to each customer.

1. Light conditions Sufficient light: Please make sure to install the solar lights in a location with sufficient light and no blocking shadows on the light-facing surface of the solar panels throughout the day. This ensures that the solar panel receives direct sunlight, thus maximizing power generation efficiency. Avoiding Shadows: It is recommended to avoid installing solar lights in the shade of trees, near buildings, or in other areas that may create shadows. 2. Orientation and Angle Orientation: In the northern hemisphere, it is recommended that solar panels be oriented due south (can be slightly west of 5 degrees in order to better receive sunlight at about 1 o'clock in the afternoon, when power generation is usually higher). Angle Adjustment: For best results, adjust the angle at which the solar panel is tilted to the horizontal according to your local latitude.
