The possibility of a building burnt down as a result of fire is a sight that no one wants to experience. That is the reason why fire protection engineers are hired before a building or apartment is constructed. When you are wondering who needs fire protection engineer, then a first name that you need to know will be the architect from the building. Exactly like an architect is essential to make sure that the style of the property is ideal and resistant to all ends; a fire protection engineer ensures that the property is protected from possible probability of fire.

Having fast answer from the firefighting pros is acceptable but won’t it be great if the fire never occurred? You need to imagine “what if” as an alternative to going through the dreadful experience of your building being on fire. Fire protection engineers glance at the model of the property first and then chart the escape routes to be taken in a fire. Also, they are accountable for installing many fire protection items in and outside the building. Water hosepipes connected to the main water supply, and checking the fitness of the fire extinguishers are among the duties that the fire protection engineer carries out if they are hired.

Difference Between Cragin Chicago Fire Protection Engineers vs Tech

The Society of Fire Protection Engineers carries a precise concept of Fire Technology versus Protection Engineers. The two positions demand a solid education in fire technology and experience as being a firefighter typically.

The engineers use principles to use systems and methods setups in different structures that help protect people and animals from harm during fires. Engineers examine the location where the biggest fire risks lie and where to add protection including sprinklers. They ensure that the utilization of buildings and any materials inside them are created to keep threats to a minimum.

Engineers will even manage the connection and maintenance of smoke detectors, alarms systems, and definately will carry out investigations of fires after it happens. This can help them prevent such things from occurring later on.

This particular position employs scientific principles to help you improve the safety of men and women in commercial buildings. A fire technician works to carry out the testing and repair of the systems which have been arranged and outlined from the engineers.

These people also needs to have the highest education and firefighting experience to function within the field. They could work to aid put in sprinklers and fire alarm systems however they tend not to plan the design of these systems like the engineers do. Even with all of this information you would like additional details on fire sprinkler system engineer services in Cragin Chicago by NY Engineers you should stop by at our blog.

HVAC Engineering: Understanding Air Balancing in Ventilation Systems

Construction Engineering Degree

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.
