Lately huge crowds have been stopping by our website in search of Electrical Engineering in the Chicago area. That is due because of the following we have develop in this types of projects. Nevertheless, a lot of general contractors from Hickory Hills to Northbrook, do not know that NY Engineers is also the ideal choice for anyone looking for HVAC Chicago, IL.

The pursuit of cost effective buildings involves power efficient HVAC system design. This will likely include systems for architectural enclosure, domestic water heating, lighting, HVAC, and vertical transportation. The loads for the HVAC systems can come primarily from five different places including lighting (cooling), the building envelope (cooling and heating), ventilation (cooling and heating), equipment for program use (cooling) and occupancy (cooling).
The ventilation load will be a purpose of either the machines required to be able to introduce it in to a space and control contaminant concentration or the quantity of persons which will be in the area. In nearly all climates within the southwestern and eastern areas of the united states, to reduce outter air movement helps you to save energy whenever the exterior air is either humid and warm or very cold.
Controlling the ventilation rate will probably be determined by occupancy which is called a kind of demand control ventilation. This really is a common type of energy conservation policy that is utilized for spaces with intermittent or dense occupancy. Having cooling and heating loads dropped as low as possible can be achieved through the use of a high performance building envelope, occupancy sensors, and high performance lighting that apply daylight response of lighting controls.

Chicago HVAC Engineering services versus HVAC Technicians

If you’ve ever considered the distinction between a HVAC Technician vs HVAC Engineers, then please read on:

HVAC engineers would be the folks that oversee the installation of air cooling systems both for commercial and residential buildings. They spend lots of their time in offices doing advanced level supervision and arranging of installations but they do also stop by job sites every once in awhile.

But, HVAC technicians have a tendency to do a lot of hands-on work  that deals with maintenance and repair. A HVAC tech may work together with an engineer to complete some of the installation task, specifically for smaller jobs. Generally HVAC technicians do considerably more travel and may spend considerable time identifying leaks, changing filters, doing recharges or getting rid of old and outdated systems that use old refrigerants.

HVAC engineers might have the ability to make more decisions about systems that are employed, plus they would be the folks that would offer assistance with one of the most sensible refrigerants and which systems would best suit a larger building. In the trade, there is some challenge between ‘the suits’ and ‘the ones that get their hands dirty’, but the two jobs require a good expertise in how air-con does work. Nowadays many Internet users have been crawling the NY Engineers website searching for things like HVAC Chicago NYE. Nevertheless, the focus of our company is to be the number one choice for anyone looking for a HVAC Chicago and or any of our other services including Sprinkler Design Engineering services. We ask that those searching for more details about our Air Conditioning, Heating & Cooling (HVAC) Engineering Firm in Chicago Illinois checks out at our blog.

Technical Standards Used by an HVAC Engineer

Construction Engineer Job Description

The job of an HVAC engineer includes the design of heating, ventilation and air conditioning systems according to the needs of each building. There are many HVAC industry organizations, and they have published standards to guarantee the correct design and installation of these important building systems. HVAC standards apply throughout the USA, and local building codes normally use them as reference – some standards have even been adopted internationally.

An HVAC installation must keep adequate indoor conditions for human occupancy, and these include ambient temperature, relative humidity and outdoor air supply. HVAC systems are characterized by their high energy consumption, exceeding all other building systems combined in residential and commercial applications. Energy efficiency measures are strongly recommended to reduce their operating cost.

The following are some of the main industry associations that publish technical standards for HVAC systems:

  • ACCA – Air Conditioning Contractors of America
  • ARI – Air Conditioning and Refrigeration Institute
  • ASHRAE – American Society of Heating, Refrigerating and Air-Conditioning Engineers
  • NFPA – National Fire Protection Association
  • SMACNA – Sheet Metal & Air Conditioning Contractors National Association

How an HVAC Engineer Applies Standards in Project Design

Technical standards provide calculation procedures for many aspects of HVAC design, considered the best practices in the industry. For example, the ASHRAE Handbook is one of the most important standards for mechanical engineers, and it consists of four volumes: Fundamentals, Refrigeration, HVAC Applications, and HVAC Systems and Equipment

The ASHRAE Handbook is constantly being reviewed and updated by technical committees. An HVAC engineer who is an ASHRAE member gets the latest edition each year as one of the membership benefits. The Handbook is available in printed, CD-ROM and online versions.

ASHRAE also has Standard 90.1, which has been used nationally and internationally to improve the energy efficiency of buildings, and many local energy codes use it as reference. The Standard 90.2 is similar, but focusing on low-rise residential constructions.

ACCA has published a set of technical manuals with calculation procedures for many aspects of HVAC design, as well as equipment selection guidelines. There are both residential and commercial versions of the ACCA manuals, covering the following topics:

  • System concept
  • Load calculation
  • System zoning
  • Air distribution
  • Equipment selection
  • Duct size calculation
  • Adjustment, testing and balance

SMACNA standards are very important in HVAC installations that use air ducts, since they provide the design requirements for both sheet metal and fiberglass ducts. By following the calculation procedures in SMACNA standards, HVAC engineers can ensure that air ducts are properly sized, while meeting airflow and static pressure requirements.

NFPA standards deal with fire protection, which is a very important aspect for heating equipment that burns natural gas, heating oil or any other fuel. One of the NFPA standards is the National Electrical Code (NEC) – it applies for all circuits that deliver power to HVAC installations, as well as their protection systems.

Industry standards may seem overwhelming at first, but they guarantee high performance and safety when designing building systems. A qualified HVAC engineer is familiarized with all applicable standards, and can use them effectively during the design process.
