Which brand of ventilation fan should I choose?

With economic development, outdoor environmental air quality is becoming more and more serious, which indirectly makes indoor air quality unstable and seriously challenges people's health. This puts higher demands on ventilation fans, which are responsible for refreshing indoor air. Require.Here, professional ventilator companies represented by Fujitec Hardware and Electrical Appliances Company have launched a new low-carbon energy-saving trend this summer with technological innovation and industrial upgrading, bringing new breakthroughs in improving the air quality of people's indoor working and living environments.It is understood that the National Energy Basics and Management Standardization Technical Committee organized and carried out the formulation and revision of 32 energy efficiency standards.During the implementation of energy efficiency standards in my country, cumulative electricity savings were 292.5×1012 kilowatt hours, equivalent to 142 million tons of standard coal in primary energy.The household appliances that have implemented energy efficiency standards are household refrigerators, room air conditioners, electric washing machines, color televisions, rice cookers, electric fans, gas water heaters, and frequency converters.

Typhoon 'Miaobai', the first typhoon to affect my country this year, formed on the 11th and is expected to make landfall on the coast from Zhuhai to Shantou, Guangdong this evening to night.Affected by the combined influence of typhoons and shear lines, heavy rainfall will occur in Guangdong, Zhejiang, Anhui and other places, and local rainfall in Guangdong can reach heavy rainstorms.In this regard, China Weather Network specially interviewed Dong Lin, chief forecaster of the Central Meteorological Observatory, to analyze in detail the characteristics, impact and subsequent development of this typhoon.My friends were shocked that the tropical depression in the South China Sea intensified into this year's No. 2 typhoon 'Miaobai' (tropical storm level, English name: MERBOK; name origin: Malaysia; name meaning: a kind of bird) on the afternoon of the 11th. This is also the first typhoon to affect my country this year. At 5 o'clock in the morning on the 12th, it was located on the northeastern part of the South China Sea, about 345 kilometers south of Shanwei, Guangdong.The Central Meteorological Observatory predicts that 'Miaobai' will continue to move north-west at a speed of about 20 kilometers per hour, and its intensity will increase.

Currently, there are three types of household exhaust fans on the market: ceiling-mounted, wall-mounted and window-mounted.The ceiling-mounted exhaust fan has a better appearance and can be installed on the ceiling of the living room. The duct of this type of ventilation fan is shorter, so you need to purchase a ventilation duct that matches the duct during installation.Since this type of exhaust fan operates in one direction, it can only discharge indoor air. In addition, the length of the pipe during operation weakens the exhaust force. Therefore, it is only suitable for installation in living rooms with good air circulation, and is not suitable for installation in kitchens, bathrooms, etc. The wall-mounted type is smaller in size and can be mounted above the window. However, due to the narrow cross-section of its air outlet, the air exchange is weak, so it is only suitable for installation in small spaces such as bathrooms or enclosed balconies.The window exhaust fan is different from the first two. It has single and double two-way operation, which can exhaust indoor air and replenish fresh outdoor air into the room. Therefore, window exhaust fans are installed in bedrooms, kitchens and other rooms. Exhaust fans are most suitable.Here I introduce to you

In 2017, the first half of the ventilation industry ended on a high note. Dealers’ enthusiasm for stocking up, market agencies’ eye-catching data, and media reports all confirmed the popularity of the air-conditioning market.In the relatively dull major appliance market, air conditioners became the biggest bright spot in the first half of the year.Although there have been frequent rainfalls recently, the high temperature weather after the heavy rain seems to continue the hot market of air conditioning market.However, some industry insiders predict that the situation in the air-conditioning market may reverse in the second half of the year, and the rapid growth momentum may be unsustainable.In the first half of the year, e-commerce has been the 'engine' for growth. Compared with the first half of 2016, the performance of the air-conditioning market this year is a bit unexpected.Throughout the first half of the year, the domestic air conditioner sales market has maintained rapid growth and has become a highlight of the entire home appliance market.According to total data from CMM, from January to May 2017, the retail volume and retail sales of my country's air conditioner market reached 23.99 million units and 84 billion respectively.
