As of late huge crowds have been browsing the NY-Engineers.Com site looking for Mechanical Engineering near Chicago. This is due primarily due to the following we have built in this types of projects. Nevertheless, many builders from Alsip to Bloomington, Illinois, do not know that NY-Engineers.Com is also a top contender for anyone searching for HVAC Companies in Chicago, IL.

The pursuit of power efficient buildings involves power efficient HVAC system design. This will likely include systems for domestic water heating, architectural enclosure, HVAC, lighting, and vertical transportation. The loads for the HVAC systems will come primarily from 5 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 certainly be a purpose of either the mechanisms needed in order to introduce it into a space and control contaminant concentration or the quantity of persons that can occupy the area. In nearly all climates in the eastern and southwestern regions of america, to minimize outter air movement helps save energy whenever the exterior air is either humid and warm or very cold.
Manipulating the ventilation rate will likely be dependant on occupancy which is known as a variety of demand control ventilation. This can be a everyday sort of energy conservation approach that is used for spaces with irregular or dense occupancy. Having cooling and heating loads dropped as low as possible can be accomplished by making use of a high performance building envelope, occupancy sensors, and performance lighting that uses daylight response of lighting controls.

Chicago HVAC Engineering services versus HVAC Techs

When you have ever wondered about the distinction between a HVAC Engineers vs HVAC Engineers, then read on:

Chicago HVAC engineers are the individuals who supervise installing of air conditioner systems for residential and commercial buildings. They spend plenty of their day in offices doing more impressive range supervision and planning of installations but they do also go to job sites every so often.

In comparison, HVAC technicians in Chicago usually do more of the hands-on work with repair and maintenance. A HVAC tech may deal with an engineer to do a few of the installation work, specifically for smaller jobs. Generally HVAC techs do far more travel and may spend time and effort identifying leaks, changing filters, doing recharges or getting rid of old and outdated systems which use old refrigerants.

HVAC engineers could possibly have the opportunity to make more decisions about systems that are being used, and they would be the individuals who would offer advice about one of the most sensible refrigerants and which systems would work best with a larger building. In the industry, there exists some rivalry between ‘the suits’ and ‘the ones that will get their hands dirty’, but the two jobs require an effective expertise in how air conditioning works. As of late many Internet users have been checking out the NY Engineers website looking for things like HVAC Supply Chicago Il. With that said, the goal of our firm is to be the to go to firm for those searching for a HVAC Contractor near Chicago and or any of our other services including Value Engineering Engineering services.

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

Best MEP Engineering Firms

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.
