Today if you solicit any general contractor or developer anywhere from Dearborn Homes to Polish Village, about a reliable Architectural Engineering in Chicago, the most popular answer is contact NY Engineers. What is so well known is that NY Engineers is probably your best option for anyone looking for a fire sprinkler engineer in Evanston Chicago. At NY Engineers our crew has many years of experience designing fire protection and sprinkler systems from Niagara Falls to Garden City, NY. Now, from our Chicago office we are helping contractor and building owners in Evanston Chicago design the fire protection and sprinkler systems they need.

The possibility of a building burnt down as a result of fire can be a sight that no one wants to discover. That is the reason fire protection engineers are hired before a building or apartment is made. When you are wondering who needs fire protection engineer, then your first name that you need to know will be the architect in the building. The same as an architect is essential to ensure the style of the construction is ideal and safe from all ends; a fire protection engineer makes certain that the property is protected from possible likelihood of fire.

Having direct answer from your firefighting professionals is okay but won’t it be great if a fire never took place? You need to think of “what if” as an alternative to feeling the horrifying experience of the building being on fire. Fire protection engineers check out the design of your building first then chart the escape routes to be used in a fire. Furthermore, they are accountable for connecting many fire protection components inside and out of the building. Water hosepipes linked to the main water tank, and checking the condition of the fire extinguishers are the duties which the fire protection engineer carries out while they are hired.

Distinction Between Evanston Chicago Fire Sprinkler Tech versus Protection Engineers

The Fire Protection Engineers Society includes a precise concept of Fire Protection Engineers vs Tech. Both positions need a solid education in fire technology and know-how working as a firefighter in many instances.

The engineers use principles to apply methods and systems setups in several structures that really help protect individuals and animals from injury during fires. Engineers examine the location where the biggest fire hazards lie and where you should implement protection like sprinklers. They ensure that the utilization of buildings and any materials inside them are meant to keep risks to a minimum.

Engineers will even supervise the fitting and upkeep of alarm systems, smoke detectors, and may do investigations of fires after one occurs. This helps them avoid such incidences from happening later on.

This particular title needs scientific principles to aid increase the safety of individuals in homes and offices. A fire technician operates to carry out the testing and repair of the systems that were arranged and laid out from the engineers.

These people should also hold the highest schooling and firefighting skill to be effective within the field. They can also work to help you put in fire alarms and sprinkler systems however they tend not to plan the layout of the systems such as the engineers do. There is only so much you can save this page if you would like additional details on fire sprinkler system engineering services in Evanston Chicago by NY Engineers you should take a look at our Chicago Building Commissioning blog.

HVAC Engineering: Understanding Air Balancing in Ventilation Systems

MEP Engineering Denver

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.
