In recent times huge crowds have been stopping by the NY-Engineers.Com site searching for Mechanical Engineering near Chicago. This is due primarily due to the following we have built in this types of projects. However, many general contractors from Downers Grove to Northbrook, Illinois, are not aware that NY-Engineers.Com is also a top contender for anyone looking for HVAC Chicago

The search for power efficient buildings involves energy efficient HVAC system design. This can include systems for lighting, architectural enclosure, domestic water heating, HVAC, and vertical transportation. The loads for your HVAC systems may come primarily from 5 different places including lighting (cooling), the construction envelope (cooling and heating), ventilation (cooling and heating), equipment for program use (cooling) and occupancy (cooling).
The ventilation load will be a function of either the devices necessary to be able to introduce it in a space and control contaminant concentration or the amount of individuals that can be in the space. In the vast majority of climates from the southwestern and eastern regions of america, to minimize outter air-flow will save energy whenever the

outside air is either humid and warm or very cold.
Controlling the ventilation rate will probably be dependant on occupancy which is referred to as a kind of demand control ventilation. This can be a common type of energy conservation strategy that is used for buildings with irregular or dense occupancy. Having cooling and heating loads reduced to a minimum can be achieved by using a higher performance building envelope, occupancy sensors, and high performance lighting that utilize daylight response of lighting controls.

Chicago HVAC Engineers versus HVAC Techs

If you have ever considered the difference between a HVAC Technician versus HVAC Engineers, then continue reading:

HVAC engineers are the people that watch over the installation of air conditioner systems both for residential and commercial buildings. They spend a lot of their day in offices doing higher level organization and preparation of installations nevertheless they do also see job sites from time to time.

In contrast, HVAC technicians usually do more of the hands-on work with repair and maintenance. A HVAC technician may deal with an engineer to perform some of the installation work, particularly for smaller jobs. In general HVAC technicians do much more travel and might spend lots of time identifying leaks, changing filters, doing recharges or decommissioning old and outdated systems which use old refrigerants.

HVAC engineers could have the opportunity to make more decisions about systems that are employed, and they also will be the individuals who would offer assistance with the most sensible refrigerants and which systems would be perfect for a bigger building. In the industry, there is certainly some challenge between ‘the suits’ and ‘the ones that will get their hands dirty’, but both jobs require an effective understanding of how air-con works. Nowadays a lot of individuals have been reading our website looking for HVAC Chicago NYE. With that said, the goal of our organization 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 everybody looking for more info about our Air Conditioning, Heating & Cooling (HVAC) Engineering Firm in Chicago Illinois takes a look at our blog!

Selecting the Right Type of Electrical Raceway for your Architectural Engineering Project: Nonmetallic Conduit Options

Is There A Demand For Mechanical Engineers In The Future

Our previous article covered the main types of metallic conduit for electrical conductors, and now we will discuss nonmetallic conduit and its applications in architectural engineering and other engineering areas. Nonmetallic conduit is normally the more affordable option, providing improved electrical isolation and corrosion resistance, while reducing the degree of physical protection.

Like with metallic conduit, all electrical installations must be according to the NFPA National Electric Code and local electrical codes. Conductors are not intended for unprotected installation, except for specific types that include metallic armor or polymer sheathing.

Keep in mind that this article is no replacement for electrical codes; the technical information provided here is very general. When working with engineering projects that involve electrical installations, you should check the specific code requirements for each application.

Rigid Polyvinyl Chloride Conduit (PVC)

PVC is possibly the most common type of nonmetallic conduit used in architectural engineering projects, being lightweight and affordable, while offering decent mechanical resistance for its low weight. In addition, it is virtually unaffected by humidity and corrosion, and is also an electrical insulator. However, the insulating properties of PVC are both a benefit and a disadvantage: the conduit itself cannot be electrified, but a grounding conductor becomes mandatory as a result, while metallic conduit can be used as both raceway and grounding in various applications.

PVC also offers features that simplify installation: it can be heated for quick manual bends, recovering its rigidity once it cools down. In addition, its low weight simplifies handling, and the conduit is easy to cut. PVC fittings are unthreaded and designed for slip-on installation, using solvent cements. PVC pull boxes also bring the reduced weight advantage, making them easier to handle and install.

This type of nonmetallic conduit is available with three different wall thicknesses: Schedule 20 is the thinnest, Schedule 40 is intermediate, and Schedule 80 is the thickest. Trade sizes range from ½” to 6”.

  • Schedule 20 PVC, with its thin walls, is not approved by the NEC for electrical installations. Therefore, it is used mostly in communication systems.
  • Schedule 40 PVC is the general-purpose option, adapting to a wide range of applications.
  • Schedule 80 PVC is used there conduit is exposed to physical damage. It is more expensive than Schedule 40, but its added strength increases the allowed applications.

The use of PVC conduit is not allowed in hazardous locations, areas where the ambient temperature exceeds 50°C (122°F), or applications where conductor insulation temperature exceeds the rated temperature of PVC. When used for lighting circuits, PVC cannot be used as physical support to hang lighting fixtures. Although the code does not prohibit its use with low ambient temperatures, consider that extreme cold can make PVC brittle, offering reduced protection for conductors.

High Density Polyethylene Conduit (HDPE)

HDPE is a type of nonmetallic conduit for applications where the circuit is buried or encased in concrete. It is not approved for indoor use or for exposed installation. Like PVC conduit, HDPE is not allowed in hazardous locations unless the code makes a direct exception, and it subject to the same ambient temperature and conductor insulation temperature limitations. The approved HDPE trade sizes range from ½” to 6”.

Reinforced Thermosetting Resin Conduit (RTRC)

RTRC is more commonly known as fiberglass conduit. Its applications are very similar to those of Schedule 40 PVC, but there is one key advantage: PVC can become brittle when exposed to very cold weather, while RTRC conserves its mechanical properties. RTRC is suitable for exposed or buried installation, indoor or outdoor use, and is unaffected by humidity and corrosion.

The applications where RTRC is not allowed are similar to those of Schedule 40 PVC: hazardous locations, luminaire support, and areas where it is exposed to physical damage or high temperature. Like with PVC and HDPE, trade sizes range from ½” to 6”.

Liquidtight Flexible Nonmetallic Conduit (LFNC)

LFNC has a self-explanatory name: it is a type of nonmetallic conduit intended for connections and cable runs with obstacles that are difficult to bypass with rigid conduit. LFNC is a versatile option, approved for various indoor and outdoor applications. Usage is not allowed where it will be exposed to damage, in hazardous locations, or if temperatures exceed conduit ratings. Like PVC, LFNC is vulnerable to extreme cold: it may become brittle, losing its flexibility. Unless codes make an exception, LFNC should not be used in runs longer than 6 ft or with circuits above 600V. Approved trade sizes range from ⅜” to 4”.

Electrical Nonmetallic Tubing (ENT)

ENT has similar applications to LFNC, but can be used for runs longer than 6 feet. In indoor locations, ENT can be either exposed or concealed. It resists moisture and corrosion, but can only be used outdoors if encased in concrete or protected from sunlight. Direct burial is not allowed, and it can only be installed exposed to the sun if specified as sunlight resistant.

ENT trade sizes range from ½” to 1”, and it is subject to the same usage restrictions that apply for many other types of nonmetallic conduit: hazardous locations, high temperatures and luminaire support.

Additional Recommendations from an Architectural Engineering Professional

Although each application is unique, non-metallic conduit generally offers a cost advantage over metallic conduit, giving up on some physical protection. However, keep in mind that metallic conduit may be mandatory in various architectural engineering applications; for example, the most demanding environments typically require rigid metal conduit (RMC) or intermediate metal conduit (IMC).

To achieve the best results in electrical installations, working with qualified professionals is highly recommended. In new construction, you can achieve drastic cost reductions with smart design decisions. For example, energy efficiency reduces the electrical load, which in turn reduces conductor and conduit diameter.
