As of late if you approach any contractor or developer anywhere from Lakeview Chicago to Merchant Park, about a reliable Electrical Engineering in Chicago, the most popular answer is contact NY Engineers. What is so well known is that NY Engineers is probably your top choice for anyone looking for a fire sprinkler design engineering in Mount Greenwood Chicago. At New York Engineers our crew has many years of experience designing fire protection and sprinkler systems from Ithaca to Medford, New York. Today, from our Chicago office we are helping general contractor and building management companies in Mount Greenwood Chicago design the fire protection and sprinkler systems they seek.

The possibility of a building burnt down because of fire is really a sight that no one wants to experience. That is the reason why fire protection engineers are hired before a building or apartment is built. When you are wondering who needs fire protection engineer, then this first name that you should know will be the architect of your building. Exactly like an architect is vital to ensure the style of the construction is ideal and safe from all ends; a fire protection engineer makes sure that the property is protected from possible likelihood of fire.

Seeing fast reaction from the firefighting experts is acceptable but wouldn’t it be better if a fire never took place? You should imagine “what if” as an alternative to going through the horrifying experience of your building being on fire. Fire protection engineers glance at the model of the construction first then plan the escape routes to be used during a fire. Also, they are accountable for adding several fire protection items inside and outside the structure. Water hoses and pipes linked to the main water tank, and checking the fitness of the fire extinguishers are a few of the duties the fire protection engineer performs when they are hired.

Difference Between Mount Greenwood Chicago Fire Protection Engineers vs Tech

The Fire Protection Engineers Society has a explicit definition of Fire Technology versus Protection Engineers. Both positions call for a solid education in fire technology and skill as a firefighter typically.

The engineers use principles to utilize systems and methods setups in various buildings that really help protect folks and things from harm during fires. Engineers study where the biggest fire threats lie and the best places to implement protection such as sprinklers. They make certain that the use of structures as well as any materials in them are meant to keep risks to a minimum.

Engineers will even oversee the fitting and upkeep of smoke detectors, alarms systems, and will do investigations of fires after one occurs. It will help them avoid such things from happening down the road.

This particular title employs scientific principles to help improve the safety of individuals in homes and offices. A fire technician functions is to do the testing and maintenance of the systems that have been arranged and laid out with the engineers.

These people should also have the highest schooling and firefighting experience to be effective in the field. They can also work to help install sprinklers and fire alarm systems however they usually do not create the layout of those systems like the engineers do. There is a great possibility you would like more information about fire sprinkler engineer services in Mount Greenwood Chicago by New York Engineers you should visit at our Chicago CAD to Revit Modeling blog.

HVAC Engineering: Understanding Air Balancing in Ventilation Systems

Fire Protection Engineering Salary

Air balancing is a fundamental design skill in HVAC engineering. Depending on the intended purpose of each building area, it may require negative, positive or neutral pressurization. This is accomplished by adjusting supply and exhaust airflows: a higher air supply causes positive pressure, while a higher air exhaust causes negative pressure.

Although the ideal scenario would be to ventilate all building areas naturally, this is not possible in practice. For example, there is no way to use natural ventilation in areas that are completely surrounded by other rooms, as well as in underground levels. The purpose of ventilation can range from human comfort to facility safety: ventilation in residential and commercial settings is focused on delivering air of breathable quality, while industrial ventilation is often deployed to keep dangerous gases away from certain areas or below a certain concentration.

Indoor spaces are subject to many airflows, and they are normally measured in cubic feet per minute (CFM). We tend to think only about the outdoor air supply and the exhaust air, but consider there is also unwanted air escape (exfiltration) and air gain (infiltration). Unwanted air flows typically occur around the edges of windows or doors.

Poorly balanced ventilation systems often lead to air quality issues, according to HVAC engineering professionals. For example, negative pressurization may draw in pollutants from above the ceiling or from outdoors, and air may rush in suddenly when a window or door is opened. 

Intake and Exhaust Air Calculation

Before air balancing calculations, it is important to know the required air supply and air exhaust. There are many valid procedures, as indicated by the following codes:

  • ASHRAE 62.1 – Ventilation for Acceptable Indoor Air Quality
  • In the case of hospitals, ASHRAE 170 – Ventilation of Health Care Facilities

The total air supply is 60 cfm, while air exhaust is 150 cfm. Since exhaust is higher by 90 cfm, the result is negative pressurization. Increasing supply to balance airflow is acceptable, since the values provided in the code are only minimum values.

Assume all intake airflows are increased to the following values, in order to prevent negative pressurization:

  • Electrical room: 25 cfm
  • Corridor: 125 cfm
  • Storage: 25 cfm

This results in a total air intake of 175 cfm, which is higher than the 150 cfm of exhaust air. This causes cellar areas to be pressurized with respect to the trash room, preventing the spread of unpleasant odours. Since the airflow must be balanced at the end, the extra 25 cfm are released by exfiltration, but trash odour is confined to its intended location.

Troubleshooting Air Balancing Issues in HVAC Engineering

If a ventilation system suffers from air balance issues, do not immediately assume the cause lies in the fans themselves. Consider that system components such as dampers can be damaged, and also that air ducts can get disconnected. When in doubt, the best recommendation is getting a professional opinion from an HVAC design engineer.

When ventilation systems are equipped with variable frequency drives for fan speed control, air balancing is simplified. VFDs can adjust the rpm of both supply and exhaust fans, to match the ventilation load while keeping airflows balanced.

HVAC engineering is a complicated matter that is best approached by engineers that have specialized in this area of expertise.
