Download - Redefine Life
Among all of the human culture heritages, this is the most valuable painting. Everyday, thousands of people from all over the world swarm into the Louvre Museum in Paris, eager to catch a glimpse of the mysterious smile. For centuries, unending efforts to uncover the story behind the smile only made it more unfathomable.
Perhaps a good way to pluck out the mystery is to repaint it yourself. Yet, 25 years after doing that, I was still puzzled. It wasn’t until today, when I placed the two paintings side by side, that all of a sudden I decoded my secret: there is an unconquerable impulse in my gene longing for being younger, although it might have offended my most respected master.
Maybe what’s behind the Mona Lisa’s mysterious smile is Leonardo da Vinci’s eternal advice to mankind: no matter what, LIFE is the only thing in this world that deserves our best care.
Zhang YueCo-founder of BROAD Sept 11, 2007
What air do the ordinary people breathe?Clean air is a critical asset to all ordinary men and women.Statistics shows that total global medical fees paid for air pollution-related illnesses are far more than that paid for any other disease. Air pollution troubles the rich and makes the poor even poorer.Is there any simple and inexpensive technology that can produce clean air for mankind?
Yes, and BROAD has developed this kind of technology.
In the Past,You were probably breathing this.
Now,You can breathe this.
BROAD air quality products,equipped with electrostatic cleaners, can filter dust andbacteria TINIER than human CELLS. This protects lungs andprevents blood pollution.
BROAD redefines life.
Comparison
Conventional central air conditioning indoor units (fan coils) are nothing but a combination of “fan + coil + water pan + shell + filter”. The mesh of their filters is 0.6 mm, only a little bit smaller than a matchstick. Helplessly dirty inside, they have become seedbeds for pathogens, as their interiors are completely enclosed and never cleanable.
Conventional split units are similar to “fan coils” with only the addition of atemperature control. Some products have introduced so called “hi-tech features” such as photocatalysts andsilver ions, which are usually hoaxes.

Options and Selection Tips:
1). CO2 Sensor: Customer can select 1 piece if several fan coils are installed in a room.
2). Heat Meter: Optional if the customer doesn’t want to have air conditioning billing and energy saving management.
3). Outdoor Thermometer: Customer can select 1 piece if several fan coils are installed in a room. It is not necessary for a building of closed type (which cannot be cooled down by opening windows or introducing fresh air).
4). Lighting Remote Control: Each fan coil can control 4 lighting loops. Optional if the customer doesn’t want to control lighting by fan coil remote control or implement illumination energy saving management through BMS.
Options and Selection Tips:
5). Colors: “Standard” color of each model is white. An additional price to be charged for “basic” colors. “Optional” colors can be offered on a case-by-case basis, but additional costs may be very high. Colors can be mixed according to the customer’s color palette. Special materials are also available for special orders, such as gold-plating (though thisis very expensive with a long lead time).
6). Remote Control: Controls not only temperature and air speed, but also the room lighting. We recommend one for each room. If several fan coils are installed in a room, one for every three fan coils is recommended. They may not be necessary for public places like hotel rooms.
How can houses breathe freely?
Each BROAD fan coil is equipped with an expensive optical instrument – a CO2 sensor to monitor oxygen deficiency in real time. People inhale O2 and exhale CO2; by measuring the CO2 level, oxygen deficiency can be indicated.To “know” is very important, but to “do” is even more. To meet different building constructions, functions, purchasing power and climates, BROAD has developed dozens of fresh air products that are totally different from conventional products but are cheaper and more energy efficient. They can solve all fresh air problems comprehensively and let each building/room breathe freely.
What is the harm of oxygen deficiency?
Deficiency of fresh air inside a room will lead to oxygen (O2) deficiency and acarbonic acid (H2CO3) concentration increase in our blood. This causes an insufficient O2 supply to the brain, headache, chest pain, cold limb, sleepiness, etc. Extended stay in an oxygen-deficient environment will result in skin-coarsening, premature senility, hypomnesia, slow of response, or, even more serious, heart diseases, brain damnification and stroke. People experiencing serious oxygen deficiency may even lose their lives while unconscious.
BROAD Fresh Air System Conventional Fresh Air System
Eliminates pollution from outdoorsOutdoor fresh air is purified by electrostatic cleaner and active carbon sheet before entering the room.
Outdoor air incompletely filteredThe filters that are widely used cannot filter micro particles.
Eradicates pollution inside air ductsIn order to perfectly match different construction styles, BROAD provides dozens of different products and optional accessories.
Serious pollution inside air ductsAir ducts in a mansion may outstretch several kilometers. Air ducts are usually not cleaned in years or even in the entire lifespan, making air ducts even dirtier than the inside of a drain.
Well-proportioned fresh airFan coils and fresh units in each room are equipped with CO2 sensors, which monitor for fresh air deficiency and excess 24/7.
Unbalanced fresh air CO2 sensors are not used. This may result in excessive fresh air in some rooms and not enough fresh air in other rooms.
Many alternatives•Dozens of models and accessories available.•Custom design can be made, suitable for fresh air system modifications of old building.
Few choicesOnly two modes all over the world.
Space saving•“Direct fresh air system” takes almost no space.•“Exhaust air duct system” is 50% space saving.•The space cost saving can be higher than the investment on equipment.
Takes up a lot of spaceAir ducts outstretch horizontally and vertically into a building and occupy large amounts of space.

INDOOR AIR POLLUTION BASICS
According to the World Health Organization (WHO), diseases brought by indoor air pollution are 5 times more common than those brought by outdoor air pollution.
The United States Environmental Protection Agency (US EPA) and Health Canadaproved that 68% human diseases are related to air pollution.
In addition to outdoor sources, indoor pollution comes also from air conditioning, ventilation ducts, building materials and furniture. People who work indoors often suffer more.
Microscopic particles in the air are the most harmful, especially those particles that are less than 2.5 µm (0.0025 mm) in size, which can enter human cells and blood streams.
Everyone breathes 17 kg of air a day – 11 times more than the amount of drinking water consumed. Thus, breathing purified air is more important than drinking purified water.

THE MIRACULOUS ELECTROSTATIC CLEANING TECHNOLOGY
The electrostatic cleaning technology is not new. It was mainly used for smoke stack cleaning in power plants. It is BROAD’s innovation that has popularized this technology. BROAD patents include:
1. Large absorbing capacity with a compact structure.
2. Three-level current adjustment that can satisfy any place with different degrees of pollution.
3. Constant static voltage and current ensure that no sound of electric shock is heard in any humidity condition and ensure absolute safety.
This seemingly simple innovation has nevertheless changed history. Ever since, people have been able to easily get air that is dust-free and bacteria-free and probably live 30 years longer.
Functions
1. Eliminate dust, bacteria, viruses, mold and fungi in the air as tiny as 0.1 µm (0.0001 mm).
2. Trapped bacteria, viruses, mold and fungi are killed by 6,000V static electricity.
3. Release a moderate amount of ozone (O3)
Striking Benefits
1. Breathe more comfortably
2. Protect against infectious diseases
3. Dustless
4. Minimize the risk of infection
5. Protect against cancers
THE MIRACULOUS ELECTROSTATIC CLEANING TECHNOLOGY
CO2 sensorPeople inhale O2 and exhale CO2. By measuring the CO2 level, oxygen deficiency can be indicated. HealthyCO2 levels are under 1000 ppm. The hi-tech opticalCO2 sensor is used to monitor the O2 deficiency status. Due to its high cost, conventionally only a few areinstalled even in a 5-star hotel. BROAD recognizes the seriousness of health degradations caused by oxygen deficiency.
Active Carbon SheetActive carbon can trap all kinds of chemical gases. Once saturation of the sheet occurs, replacement is needed. There are two common kinds of active carbon: globular granule and meshy carbon sheet. For the latter one, replacement is usually needed every two months. For newly furbished houses, replacement is recommended within two weeks.
