Direct Fired Chiller
Waste Heat Chiller
The input heat energy heats LiBr solution to 140℃ and generate vapor, which is then condensed into water by cooling water. When the refrigerant water enters evaporator (in high vacuum condition), its temperature goes down immediately to 5℃. And it is sprayed over the evaporator tubes, and chilled water from 14℃ drop down to 7℃ to make cooling. The refrigerant water absorbs heat from air conditioning system and evaporates, then is absorbed by concentrated LiBr solution from the generators. The cooling water takes away the heat and rejects it into the air. Diluted solution is pumped into HTG and LTG separately to be heated to begin the process all over again.
Notes: Lithium Bromide is a salt of strong hygroscopicity, nontoxic and harmless, with no greenhouse effect and no damage to the ozone layer.
The input heat energy heats the LiBr solution. The vapor produced by the solution heats the heating water or hot water in tubes, while condensate returns to the solution to be heated and the cycle repeats. As “separate heating” is adopted, the heating cycle becomes very simple, just like a vacuum boiler. Therefore, the lifespan of the chiller can be doubled. A separate heat exchanger can provide dedicated hot water while cooling or heating operation is stopped.
So, only BROAD has the unique technology in the world that can realize “three functions in one unit”: cooling, heating and hot water simultaneously or dedicatedly.
- Cooling, heating, hot water (seperately or simultaneously)
- Provide chilled/heating water for central air conditioning system
- Produce chilled water over 5℃ and heating water below 95℃.
- 233~11,630kW (66~3,307Rt)
- Diesel, LPG, Natural Gas and Town Gas (for direct fired chillers).
- Waste heat from power generation or industrial waste streams i.e steam, hot water, exhaust, etc. (for waste heat chillers).
AS THE GLOBAL LEADER OF NON-ELECTRIC CHILLER,
WHY BROAD ALSO MAKES ELECTRIC CHILLER ?
BROAD non-electric chiller is the world’s most efficient equipment when evaluating
the efficiency of “primary energy”, also it is the only central air conditioning that
can generate chilled water, heating water and sanitary hot water with the highest
reliability, the longest life span and the quietest operation. However, the following
reasons determine that we are manufacturing power-efficient chiller now.
1. Many areas have no access to natural gas or waste energy sources.
2. Some inquires need cooling only, or the yearly operation time is too short to use
multi-function air conditioning.
3. Specific locations powered by wind, hydro or solar PV has great potential to reduce
CO2 emissions.
4. BROAD Power-efficient Chiller is more efficient than traditional electric chillers.
5. BROAD Packaged Water Distribution System is more efficient than traditional distribution
systems.
6. BROAD Power-efficient Chiller can be combined with BROAD non-electric chiller and
BROAD CHP system, which has higher efficiency and energy flexibility than single
energy source equipment.
VALUES OF BROAD POWER-EFFICIENT CHILLER
The Integrated Part Load Value (IPLV) of the chiller can reach 10. This high IPLV can reduce energy consumption by 40% when compared to traditional electric chillers. BROAD Packaged Water Distribution System can reduce electricity consumption up to 76% when compared to conventional field-built systems.
The magnetic oil free and zero friction technology can save up to 40% energy cost and 90% of maintenance cost when compared with traditional electric chillers. BROAD PLC “Smart anti-surge control” module insures the chiller always operate in a safe range. The integrated design of the BROAD chiller, water distribution system and stainless steel metal enclosure reduce design cost and field installation costs for customers.
Compared with the traditional electric chillers, BROAD packaged chiller reduces volume by 30~50% and weight by 30%. BROAD Packaged Water Distribution System and stainless steel metal enclosures can be installed outside which reduces mechanical room footprint requirements.
BROAD Packaged Water Distribution System and stainless steel metal enclosure eliminate risk and reduce system design, procurement and installation errors. BROAD Intelligent Control System (ICS)can be automated for free operation of the chiller and water distribution system. BROAD Global Internet Monitoring System provides customers with 24/7/365 fault prediction, analysis and energy-saving management tools.
75% energy savings versus traditional on-site assembled pumping system
In traditional central air-conditioning systems, the supply and distribution system of cooling water, chilled water and hot water consumes 1/3 of the whole system’s energy. To correct this apparently unreasonable phenomenon, BROAD has pioneered and improved packaged pumping distribution system which saves an average of 75% energy consumption instantly. Simultaneously, the reliability and quality control of the pumping distribution system has been raised to the same level as that of BROAD chiller.This incredible energy saving miracle is indeed not mysterious, it’s attributed to the “zero-resistance filter”and“optimal variable flow intelligent control technology”BROAD has invented. Another BROAD industrial research solution for the 21st century, to replace “inefficient methods of field erected systems” with high quality factory production and low energy engineered systems for our customers.
AIRPRO MASK
AirPro Mask is a Powered Air-Purifying Respirator system. It includes a KN95 mask and a filtration unit with a 3-speed fan, HEPA H13 filter, and chargeable lithium battery. Positive air flow is delivered through the mask, providing the utmost in comfort as well as safety. It is particularly beneficial for professionals and individuals who must wear a mask throughout a full shift. The mask itself is replaceable, but the filtration unit is designed for long term use. The AirPro Mask filters PM2.5 by 99.9%. The product is very effective against pathogens, pollen and dust, and is ideal for consumers and for professionals in a broad range of industrial/occupational settings.
The BROAD Electrostatic Air Purifier is the only product on the market that serves four distinct functions: Electrostatic Dust Cleaning, Ozone Disinfection, Toxic Gas elimination, and Oxygen Deficiency Monitoring. The Ozone generator destroys viruses and bacteria up to 10,000 times smaller than PM2.5. The area covered is up to 9500 sq ft depending on which model is deployed. The technology also enables setting up “Disinfection Cabins” at the point of entry for hospitals, factories, office buildings, schools and other facilities.
BROAD Purifier Saves Our Family from Pollution
- Fewer illnesses such as cough, cold and influenza.
- Far less like to to catch chronic diseases such as rhinitis, laryngitis and pneumonia, and can lessen the effects of asthma.
- The risk of cancer, diabetes and other major diseases can be reduced dramatically
BROAD Purifier Saves Our Family from Pollution
Electrostatic air purification technology is at the top of the pyramid of air purification technologies, and its super filtration efficiency is superior to the physical filtration methods ( paper filter):
- Static electricity helps absorb infinitely tiny particles ( 10,000 time smaller than PM2.5)
- 6000V high-voltage static electricity kills microbes such as virus and bacteria, and clears away pollen.
However, two worldwide global challenges must first be faced:
- The capacity of static electricity changes with air humidity level. Excessive ozone is typically released at high humidity, while purification efficiency will be reduced at low humidity. BROAD’s unique patented technology of constant current and voltage has successfully solved this problem.
- The electrostatic tungsten filament and the electrode grid will short out when coming into contact with fibers in the air or mosquitoes. A crackling sound will be heard and the tungsten filament will even get burnt. BROAD’s patented technology of an independent resistor circuit for every single tungsten filament has solved this problem.
BROAD Purifier Makes Viruses and Germs Less Scary
During the worldwide novel corona-virus pneumonia crisis in 2020, we found ozone disinfection to be the most effective measure with the least side effects and lowest cost to prevent the virus from spreading.
Dozens of anti-epidemic hospitals, such as the Leishenshan Hospital, Huoshenshan Hospital, and several mobile cabin hospitals have used BROAD Purifiers. During the anti-epidemic period, we have also applied ozone at different concentration levels to hospital wards, work areas and living areas for 24-hours uninterrupted operation, effectively curbing the spread of viruses.
Air Disinfection – Additional Ozone Function
Ozone molecules consist of 3 oxygen atoms (Q3). About 95% of the ozone in the atmosphere comes from the photo-chemical reaction between the sun and plant volatiles, as well as the ionization between lighting and air. This product uses static electricity to simulate lighting to produce ozone.
Full coverage: When the disinfection function is activated, the ozone generator continuously generates ozone, which quickly penetrates into every corner and gap of the dwelling, overcoming the problem of ultraviolet sterilization which can only go straight up and down, leaving a dead zone of disinfection and the problem of eye injury.
High efficiency: A large number of scientific experiments have proved that the efficiency of ozone sterilization and antivirus is more than 200 times hight than that of chlorine.
Ultra-cleanliness: Ozone oxidizes microorganisms and organic matter in the air into carbon dioxide and water, and the excess is decomposed into oxygen without any residue. In contrast, chemical sanitizers such as 84 disinfectant (key component NaCIO) are toxic to the human body and have secondary pollution of residues, damaging the ecosystem.
Low cost: Using only small amounts s of electricity and no consumables, the cost is much lower than chemical disinfection.
Trustworthy: Since the invention of electrostatic duct cleaning technology in 2005, BROAD Clean Air has been devoted to researching the benefits and harms of ozone, and carefully exploring the rational application of ozone in different places and epidemic situations to find an effective way to prevent the global outbreak of infectious diseases, pioneering the utilization of ozone for the benefit of mankind.
4 in 1 Function
BROAD purifier is the only products in the world with 4 in 1 function ( BROAD patented).
- Electrostatic Dust Cleaning: The tungsten filament of the electrostatic cleaner continuously releases about 6000V high-voltage static electricity, and charges all particles with a positive charge, which will then be absorbed by a negatively charged electrode grid. Electrostatic cleaner can absorb infinitely small particles ( 10,000 time smaller than PM2.5).
- Ozone Disinfection: Equipped with ozone generator, the purifier can be used for air disinfection and object disinfection in infectious disease wards, operation rooms and places where people are gathered during the outbreak of epidemics, effectively killing bacteria and viruses. Even in seasons without infectious diseases, keeping a certain concentration of ozone indoors is conductive to preventing harm form microorganisms such as influenza virus and motes, as well as pollen.
- Formaldehyde Elimination: The active carbon sheet absorbs various volatile and toxic chemical gases(VOC) such as formaldehyde, benzene, nicotine, etc. In addition, ozone itself is strong oxidant, which can transform organic matter (VOC) into carbon, and itself into water an oxygen. For newly decorated or renovated rooms, use high concentration of ozone for fumigation for 1-2 days to completely eliminate formaldehyde.
- Oxygen Deficiency Monitoring: The CO2 sensor constantly monitors indoor CO2 concentration levels to alert customers if there is indoor oxygen deficiency.
Parameters
- Applicable area depends on the degree of environmental pollution, etc.
- Since there is nearly no filtration resistance for electrostatic dust cleaning, the power consumption is extremely low. It is economical to work continuously 24 hours unless there is no one in the room.
- The filtration energy efficiency for BROAD Purifier is 9. China’s National Standard as per GB/T 19901-2015 is qualified, 5 is highly efficient.
