Air Showers Effective for Clean Rooms!!!

Air Showers are self contained chambers installed at entrances to clean rooms and controlled environments. Air showers quickly and effectively remove particulate that otherwise would be carried into a clean room. They are intended as the "final polish" after gowning prior to entering a clean room environment. Air showers from Clean Air Products are ideal for a variety of clean room applications in industries including pharmaceutical/ bio processing; semiconductor/electronics; and automotive painting and finishing.Worker cleanliness is essential in any workplace where contamination control is the norm. Although water showers can help you reduce soil on your body, air showers are an effective means of removing contamination from your work clothes.

Facilities use air showers to minimize the movement of biological contaminants attached to other particles. Air showers are enclosed chambers with entry/exit systems, and they use door interlocks and timers to direct strong bursts of air that dislodge contaminants on personnel or parts.The greatest source of particulate contamination in a clean room is the operator. Air showers are installed between change areas and the clean room. The air shower enhances clean room operating protocol by serving as a reminder to all operators that they are entering a controlled environment. Personnel therefore develop the habit of gowning up properly before entering the air shower.

Identifying Users of Air Showers..

Electronics manufacturers use air showers because of the sensitive nature of constructing integrated circuits or chips. Strict sanitation is also required in the pharmaceutical industry, where the design and development of drugs and medications are prevalent. Air showers are also employed in the biotech industry, where clean rooms are used to experiment with bio-molecular and cellular processes. Similarly, in the medical industry, workers take air showers to ensure that surgical procedures are kept sterile.

Air showers are beneficial for contamination control across many industries. By making the work atmosphere cleaner and safer for personnel and products, air showers form a reliable link to clean rooms. Users of air showers can help to maintain high standards of air cleanliness by following proper protocol and operation parameters.

Ductless Ventilation System !!

Ductless ventilation system is the latest in applying modern technology in building management system. Hither to car parking ventilation has been done with conventional duct system. In this system a set of fresh air fans and exhaust fans are used. Through a well laid out duct the fresh air is being pumped to the car parking area and the exhaust fan sucks these air and remove it out.

A series of jet fans and exhaust fans are used in ductless ventilation systems for the removal of exhaust. The jet fans provide a high velocity to the gas stream entering into it and pass it onto the next exhaust or jet fan which then releases the gas stream to the outside surrounding while also replacing it with fresh air from outside.

The first and foremost advantage that these systems have over ducted ones is that due to the lack of ducts, it is extremely to install ductless systems in car parking spaces. The time and cost taken for the installation is also considerably lower.

Advantages of Ductless Ventilation Systems-

• With the absence of ducts, the weight of the installation is also less. The jet fans are made of lightweight, less density corrosion resistant aluminum and the outer casting is made up of stainless steel.

• The overall height of the basement gets restricted due to the installation height of the ducts and then the parking space is also convenient for small and medium cars and larger cars do not fit in. Whereas with ductless systems, one does have to face such issues.

• The jet fans in ductless systems are synced with CO2 detectors and they automatically adjust themselves to work according to the CO2 level in the parking space. Whereas in ducted systems, the fresh air and exhaust fans would be required to work all day leading to more energy consumption.

• The jet, impulse or induction fans are designed to have a characteristic thrust that ensures a relatively even distribution of air.

• The jet fans can be worked in single or in both directions, according to the requirement.

In light of the above advantages that ductless systems offer over ducted ones, it can be safely said that ductless ventilation systems are ideal for underground car parking spaces in malls which already have less space and need to provide for hundreds of cars that come day in and out. The level of fresh air need to be maintained if people are to be prevented from getting suffocated and also a good ventilation system will come in handy when fire breaks out as it would neither be possible for people to vacate the space if there is smoke everywhere nor will the fire fighters be able to do their job.

Fire Fighting System !!

SAVING LIVES! PROTECTING PROPERTY!

We offer the best in quality & technology Hi-tech Wireless firefighting system with high levels of service through leading edge Research & Development. Firefighting System is one of the more significant concerns for owners and managers of commercial buildings, Safety is important for everyone whether it is residence or working place so every building might incorporate the best fire fighting system to stop the spread of fire breakouts which can create damage to property and mortality. The vast majority of the corporate workplaces, shopping centers, film theaters and even homes are provided with indispensable gears to smother fire.A fire in a commercial establishment could lead to serious injury or even death of employees and customers. To a lesser degree, fires could damage merchandise, destroy important records, ruin expensive equipment and electronics, and put a company out of business.

A fire fighting system is probably the most important of the building services, as its aim is to protect human life and property, strictly in that order.  

It consists of three basic parts:

• a large store of water in tanks, either underground or on top of the building, called fire storage tanks
• a specialized pumping system,  
• a large network of pipes ending in either hydrants or sprinklers 

Fire sprinkler systems provide a critical element of safety for occupants of buildings. Sprinklers are designed to detect heat from a fire and automatically activate, providing a flow of water that is intended to slow or extinguish a fire. By the time a sprinkler system detects enough heat to activate, a fire may already be well underway. The sprinkler can provide enough early suppression to allow building occupants to safely evacuate the building before the fire spreads or gets worse. In addition, a sprinkler system can reduce the severity of a fire enough to allow firefighters easier and safer access to the affected area.Sometimes a simple fire extinguisher is not enough. Fires can come in many different forms and can require a number of different techniques to minimize damage or prevent injury. Fire extinguishers are a very important part of every fire safety procedure. But there is more to fire protection than you may realize, and there are advantages of fire protection systems.  

Here are features of complete fire safety equipment:

• Fire Extinguishers
• Fire Alarms
• Emergency and Exit Lights
• Sprinkler Systems

Fire protection systems come in various forms and are designed to deal with fire emergencies in different ways. There are distinct advantages of fire protection systems that everyone should learn: 

• Fire extinguishers – used to immediately attack a fire that is localized to a specific area. There are different types of fire extinguishers that are made to attack certain types of fires. For example there are extinguishers for grease or cooking fires, and different extinguishers used for rubbish fires. 
• Fire blankets – the fire blanket is helpful when a small fire has occurred and needs to be smothered quickly. Because fire relies heavily on oxygen in the air a blanket can be extremely effective. However if the blanket is not used correctly or it is used on a large fire there could be further damage or injuries, so training is necessary to make sure fire blankets are used correctly. 
• Sprinkler systems – the use of water is very common to extinguish a fire. Water can cool the fire, depriving it of heat in order to grow. Water can also smother the fire, reducing its ability to consume oxygen. When a large fire has occurred a sprinkler system can quickly extinguish the fire and minimize damage or injuries. While a sprinkler system can be messy after it is used many people would prefer using some mops and towels to clean up instead of dealing with smoke or fire damage.

Poorly Maintained Duct System Affect Air Quality?

If your place is equipped with an HVAC system, it may seem like you no longer need to worry about the air quality. Air quality is affected by a wide range of factors, an improperly maintained HVAC and ventilation duct systems are typically at the top of the list.

Poor air quality can cause a wide range of health issues, right from headaches or congestion to asthma and other breathing disorders. It’s essential to keep the air duct and ventilation system in great shape, since its maintenance and upkeep has a direct connection to the quality of air you and your loved ones are breathing!

Let’s look at the top 5 effects of leaky or damaged air duct systems:

1. They Pull In Bad Air – Pollutants from outside your place can get into the ventilation system if there are any leaks or gaps in the HVAC return ducts. When you’re running your air conditioner or heating, the system could be pulling in and distributing contaminants throughout the buliding!
   Since return ducts pull air into the unit and then supply it through the system after conditioning, it’s crucial to check for contaminants around them. Bad air doesn’t just come in from outdoors. It can also be pulled into leaky ducts from rarely-used, musty spaces like attics, basements and crawl spaces.
2. They Create Negative Pressure – It’s not just leaky return ducts that increase the intake of bad air. From the supply side of the HVAC system, duct leakage leads to its own set of IAQ concerns by creating negative air pressure inside your building. This increases infiltration of outside air, as the system tries to balance the air pressure.
   If the amount of air being supplied through the ducts (after conditioning) is less than the amount that went into it, the negative pressure will cause more air to leak into the house through attics, crawl spaces, basements, windows and doors. Since this is unfiltered air, it can raise pollutant levels indoors.
3. They Raise the Risk of Back drafting–When you use a combustion appliance (water heater, cooking range, oven, etc.) the harmful gases emitted by it exit your house through a flue or chimney. However, if there’s negative pressure in the air around these appliances, these gases can get pulled back into the house (back drafting).
   Back drafting poses a serious risk to IAQ, especially in term of carbon monoxide poisoning. It’s more likely to be an issue if you run multiple combustion appliances in the same room, like a clothes dryer and a furnace. Leaking return ducts and even closed room doors near the central return vent can create pressure imbalances.
4. They Reduce Humidity Control – Humidity is often the main culprit to blame for diminished IAQ, since it encourages the growth of mold. Mold spores thrive in a moist, warm environment, which may be found within certain sections of a leaky duct system.
   Most HVAC systems have built-in moisture control, but if humid air is entering the buliding from outside or inside sources (damp basements, for instance), this functionality may be affected.
5. They Affect HVAC Performance – While bad air is typically filtered out by the HVAC, excessive leaks can put more pressure on these systems than they’re designed to handle. This can lead to performance or efficiency issues, increasing energy consumption in addition to affecting IAQ and comfort.

Efficient Commercial Cooling System !!!

HVAC chiller is a key component of many commercial and industrial cooling and refrigeration systems. A chiller is a machine that removes heat from a liquid via a vapor-compression . Industrial chillers are generally installed in a mechanical equipment room, beside an industrial process, or outside the building. Residential HVAC chillers can be installed in a storage tank next to the home. Chiller system changes the physical state of refrigerant to transfer heat from one area to another. The laws of pressure-temperature relationship state that increased pressure on a refrigerant increases its temperature while decreased pressure lowers its temperature. As the refrigerant circulates through the HVAC chiller, various components change its pressure and temperature, causing it to boil into a gas and condense into a liquid. During the change of state from liquid to gas, the refrigerant absorbs heat, and the refrigerant releases heat when it returns to its liquid state. A commercial chiller system is a form of air conditioning, mounted on the roof of an office building or similar structure. They come in two types: air cooled and water cooled. Air-cooled systems blow warm air from your building across a set of coils circulating refrigerant. Water-cooled systems send the heat from the air into water, which facilitates a heat exchange with a series of copper tubes containing refrigerant. It works more effectively than air-cooled chillers for larger offices, which naturally have higher demands on an air conditioning system.

Water Cooled Chiller vs Air Cooled Chiller in HVAC System

• Initial cost of air cooled chillers is lower than water cooled chillers as air cooled systems don’t require cooling towers,condenser water pumps and associated HVAC components.
• Small systems are almost always air-cooled since the extra requirements of water treatment and maintenance are capital intensive and will not be offset quickly by the lower operating costs.  Larger HVAC water chillers are almost always water cooled .HVAC engineers and technicians feel easy with maintenance free or less maintenance equipment.
• Water cooled chillers may be preferred because of  better heat transfer properties of water as compared to air cooled chillers.The primary advantage of water is that the film coefficient is 10-100 times better with water than air.Film coefficient controls heat transfer with given constant area and temperature difference.
• Water-cooled HVAC units make less noise and give more cooling per square foot.While air cooled chillers have comparatively less cooling per square foot and are more noisy HVAC machines.Noisy machines are annoying especially for occupants of nearest offices or zones.
• While comparing  air and water cooled chillers, an overall system cost (both running and installed) has to be worked out. Size of HVAC unit matters when selecting the water cooled chiller or air cooled chiller.Smaller HVAC units are usually air cooled, larger are water cooled.
• HVAC engineers have to evaluate air cooled and water cooled chillers keeping in mind various factors.Refrigeration engineer has to consider the ambient conditions (wet bulb and dry bulb), number of hours of operation, part load pattern and cost of maintenance etc.
• HVAC experts have no single answer to when asked “water cooled chiller is better or air cooled chiller?”. The fact is that “It all depends”. Water-cooled chillers will normally condense at an average lower pressure than air-cooled chillers.  This is because the water temperature will usually be less than the air temperature.If your condenser is operating at lower pressure then it is directly reflected and translated into lower operating costs.
• The difference between the wet-bulb temperature and the dry-bulb temperature gives the available difference between the condensing temperatures of water-cooled and air-cooled condensers respectively.  
• Cooling towers and/or evaporative condensers have main disadvantage of maintenance and water treatment costs. This running cost is not present in air cooled chillers.
• When comparing water cooled and air cooled chiller,scarcity of water and hence cost of water is another issue which is a point to be considered while deciding on the system.  This happens in many countries .
• Space is also of importance in some applications. Air cooled chillers can utilize open space, such as a parking lot, roof or ground level area. Although smaller in size but Water cooled chillers require a mechanical room and cooling towers.
• Air recirculation is very important for air cooled chillers.Any obstruction in the circulation of air near water chillers would adversely affect the performance of air cooled chillers.Air cooled chillers can have problems with recirculation if there are walls higher than the unit or too many units to close together. If there is a situation where outside walls are required for building code and the unit will not be receiving enough fresh air, then a water cooled application may be the best option.
• Water cooled chillers have longer life,higher efficiency,large capacity and also refrigerant containment.While looking on dis-advantatges of air cooled chillers,they have lower efficiency,comparatively short life span and available in low capacity range.

Ensure Good Ventilation to Avoid Health Hazards !!

Ventilation Control

All occupied buildings require a supply of outdoor air. Depending on outdoor conditions, the air may need to be heated or cooled before it is distributed into the occupied space. As outdoor air is drawn into the building, indoor air is exhausted or allowed to escape (passive relief), thus removing air contaminants. The term “HVAC system” is used to refer to the equipment that can provide heating, cooling, filtered outdoor air, and humidity control to maintain comfort conditions in a building. HVAC systems range in complexity from stand-alone units that serve individual rooms to large, centrally controlled systems serving multiple zones in a building. 

Some buildings use only natural ventilation or exhaust fans to remove odors and contaminants. In these buildings, thermal discomfort and unacceptable indoor air quality are particularly likely when occupants keep the windows closed because of extreme hot or cold temperatures.

In order to exhaust air from the building, make-up air from outdoors must be brought into the HVAC system to keep the building from being run under negative pressure. This make-up air is typically drawn in at the mixed air plenum as described earlier and distributed within the building. For exhaust systems to function properly, the control air must have a clear path to the area that is being exhausted. To prevent operating the building under negative pressures (and limit the amount of unconditioned air brought into the building by infiltration), the amount of make-up air drawn in at the air handler should always be slighter greater than the total amount of relief air, exhaust air, and air exfiltration through the building shell. Excess makeup air is generally relieved at an exhaust or relief outlet in the HVAC system, especially in air economizer systems. In addition to reducing the effects of unwanted infiltration, designing and operating a building at slightly positive or neutral pressures will reduce the rate of entry of soil gases when the systems are operating. 

The selection of a specific ventilator should be based on the following factors:

         

•  Job details such as the atmospheric hazard, the size of the confined space, etc
• Airflow required
• Airflow volume required at the end of the duct to control the hazards present; and Breeze to ensure worker comfort in the space.
• Duct friction loss to ensure adequate air volume reaches the end of the duct.

Aims of HVAC Control Systems:

• HVAC Control Systems are used for the following benfits:
• Lower energy cost.
•  Lower operations cost.
• Increase flexibility.
• Ensure quality building environment.
