Since 2011 many property owners throughout East Meadow, New York already know that NY Engineers is the engineering company to contact when you’re ooking for Electrical Engineering in NY. What many local building owners have not realized is the New York Engineers is also your best choice if you’re looking for HVAC Engineering services in Lansing, IL. If you want to learn more about what Lansing HVAC design engineers do? It is an exceptional job which inclides an extensive listing of obligations. An HVAC design personel will have to work through a variety of concundrums to solve the core issue. This task calls for distinct skill, competence, and the opportunity to deal with time prudently.

The moment an HVAC contractor is licensed to operate, they will likely join up with an engineering company and begin to work on various cooling, heating and refrigeration systems. Their function is usually to draw up new and additional selections according to their customer’s requirements. Every single customer will have a unique set of wants whether or not it involves building codes or personal performance expectations. Making use of this material, the engineer goes on a ride towards building something which is energy-efficient, eco-friendly and suitable for the place it might be used in – (industrial, commercial or residential. They usually are in charge of the initial creations and overseeing the actual installation.

Generally, an HVAC engineer in Lansing will likely be seen working with a design company or maybe in a consulting team depending on their many years of expertise. Many engineers move right into a consulting job as they become older and gain a better understanding of what’s expected of them.

Comparing HVAC Engineer vs HVAC Technician

HVAC Technician and HVAC Engineer are often mistaken for each other. Yet, they may have separate tasks in terms of handling HVAC systems. It’s important to know the variance both as a customer and as an expert

An HVAC technician in Lansing carries a more hands-on job, which implies they are often seen going to a customer’s home to deal with their current system. They often take care of the repairs, installations, and overall upkeep which is required from time to time. Almost all of their effort is done alongside the client, meaning they need to learn how to communicate with people properly.

With an HVAC engineer, they are accountable for designing a new HVAC system and making certain it meets exactly what a client is after. It has to fit precisely what the house owner wants whether it involves their setup, property, or anything else associated with new system. Also, they are brought in to check on HVAC creations to make certain things are all in accordance with today’s standards. This is the reason they could find themselves spending time in consulting assignments or at neighborhood engineering companies. This is the distinction between both of these vocation choices; HVAC Technician vs HVAC Engineer.

HVAC Engineering: Understanding Air Balancing in Ventilation Systems

Mechanical Engineers

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.
