Honeywell was founded in the United States in 1885, indoor air quality improvement is its important business area, its professional manufacturing history can be traced back to the middle of the twentieth century, and now it is still the world's leading brand in the field of international air quality control, the technical accumulation is quite strong, as early as the 70s of the last century, it was designated by NASA as a supplier of space shuttle environmental systems, and large domestic office buildings and hotels generally use Honeywell's fresh air system. Public institutions such as the National Museum of China are also among Honeywell's customers of the Central Fresh Air System.
In the sub-field of home-grade central fresh air system, Honeywell's overall performance is also as prominent as its brand value, its product series mainly include ER and ERN, the ER series was launched earlier, and it is also a classic work of Honeywell, with all performance indicators are relatively balanced, and the air volume specifications are covered from 250m³/h to 2000m³/h, which is suitable for large-scale apartments, villas and other family installations.
The appearance of the ERN series is more concise and bright, different tuyeres adopt a brightly colored foolproof installation design, which is convenient for workers to install and construct, and the internal DC motor and control circuit are iteratively upgraded, the operating noise is reduced by about 10%, and the expansion functions such as wind speed mode are also more abundant, and the slim structure design is also adopted, with a thickness of only 220mm, which is about 20% less than the traditional model, effectively saving the installation layer height, but the too compact space leads to its air volume specifications of only 150 and 250m³/h optional. It is more suitable for small and medium-sized families.
Although the fresh air system is mainly used for ventilation, but under the impetus of air pollution, efficient haze removal has become a hard choice index for consumers, frankly speaking, the filtration configuration of Honeywell fresh air host is relatively simple, ER series only has a metal mesh primary filter, and ERN series is only a small upgrade to double micro HEPA filter, in fact, it is not realistic to pile up materials inside the host, because the internal space of the fresh air host is very compact, and Honeywell's solution is very exquisite, That is the introduction of a separate electronic purification box.
In 1956, Honeywell invented the two-stage electrostatic adsorption particulate matter technology, which has long been in the leading position in the industry in this technical field, and can be said to be the originator of electrostatic dust collection technology, the first stage of "two-stage" is to use 8150V high-voltage ionization filament to ionize particles and attach an electric charge, and then use a 4075V high-voltage dust collection plate to adsorb charged particles, so as to achieve the purpose of rapidly purifying the air.
Because the internal structure of the electronic purification box is arranged in layers of metal plates, the airflow can easily pass through, and on the premise of ensuring the haze removal effect, the wind resistance is only one-tenth of that of the HEPA filter, and the consumption of fresh air volume is very slight. The measured ozone release concentration of Honeywell electronic purification box is 0.05ppm, which is lower than the international safety standard line of 0.1ppm, and the indoor air and the outdoor have been in a circulating state, ozone will not be enriched indoors, and the low concentration of ozone also has a certain disinfection and sterilization effect, so there is generally no need to worry.
In addition, the whole Honeywell series is equipped with a specially designed hexagonal full heat exchange core, the overall height is reduced by 15% compared with the traditional diamond-shaped design, the space structure is more compact, the hexagonal design can also increase the contact area with the airflow, the measured air exchange rate is as high as 95%, greatly improving the efficiency of heat and water molecule exchange, the maximum enthalpy exchange rate of Honeywell total heat exchanger reaches 70% of the industry's first-class, maximizing the indoor air intake to achieve the effect of "warm in winter and cool in summer, balanced in greenhouse". This reduces the power consumption of refrigeration and heating equipment such as air conditioners.
Honeywell's central fresh air system is basically the same as similar competing products on the market, 250m³/h host, auxiliary materials, electronic purification box plus installation labor costs about 15,000 yuan, because the central fresh air system involves a series of processes such as pipeline design, and offline installation, Honeywell's products are rarely sold on the online platform, and users had better contact offline agents for detailed communication.
