Difference between air pruifier AC motor and DC motor #dcmotor

Posted on 一月 17, 2019 by 

Performance
AC motor technology:
– Motor speed is affected by power supply rate
– small speed range
-Speed control is difficult
– large size and high noise

Brushless DC motor technology：
-The speed is not affected by the power frequency
– Large speed range
– Stepless speed regulation, automatic control of speed can be achieved by closed loop control and temperature or wind pressure monitoring technology
– Large starting torque
-High speed limit

Energy saving
AC motor technology:
– Motor efficiency is 40% less ‘50%
– 200W power consumption when outputting 100W
Brushless DC motor technology:
-High motor efficiency 60-70%
– 150W when outputting 100W, saving more than 30%

Safety
AC motor technology:
– large energy loss
-low efficiency
-The motor temperature rises
– low reliability
Brushless DC motor technology:
– low energy loss
-efficient
– low motor temperature rise
– high reliability

Development Trend of Water Purification Market 2019 Posted on  May 10, 2019   by  olans228 According to the offline monitoring data of AVC, the development speed of high-throughput products greater than or equal to 200L is fast and increasing. The proportion of high-throughput products is nearly 64% in the first half of the year, while the share of low-throughput products is gradually decreasing. The water purification industry is developing towards the direction of large flux, long life, high water saving, and intelligentization. More consumers have opted for high-throughput reverse OSMOSIS WATER PURIFIERS Reverse osmosis technology  has gradually become the mainstream of the market, in ultrafiltration, activated carbon, nanofiltration, and other technologies ranked first. In the first half of 18 years, reverse OSMOSIS technology products accounted for 90% of the total. Large flow for Reverse osmosis with WIFI will be very hot for the market. Welcome...

Red Dot Product Design Awards –#waterpurifier Posted on  April 24, 2019   by  olans228 the best products in the design field each year. The Red Dot Product Design Awards are accepted by manufacturers and designers from all over the world, from fashion and lifestyle accessories, consumer electronics products, to 48 participating groups such as vehicles, home appliances and furniture. . The Red Review Team, consisting of 40 international experts, follows the concept of “In search of good design and innovation” and conducts field testing, discussion and review of all entries. Only products of good quality are designed. In order to be recognized by the jury, the red dot award will be awarded. The Red Dot Awards jury not only reviews a selection of products based on a clear selection criteria, but the selection criteria will continue to evolve as new technology, social, economic and environmental needs evolve. Award-winning products must meet standards in many aspect...

PM2.5 Air Quality Index

图片
PM2.5 Air Quality Index Here provides comparisons of air quality based on factors that have been shown to increase risk from air pollution. These factors can include life stages (children and older adults), specific health conditions (heart or lung disease), and increased likelihood of exposure from being active outdoors. The Air Quality Index (AQI) is the official index for air quality across the United States. The AQI ranges from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. When AQI values are between 101 and 150, or code orange, members of sensitive groups may experience health effects. This is because they are more likely to be affected at lower air quality levels than everyone else. For example, children and older adults, people with lung disease, and people who are active outdoors (outdoor workers) are at greater risk from exposure to ozone. Older adults and children, and people with heart or lung disease ar...
