Recently huge crowds have been visiting our site searching for Electrical Engineering in the Chicago area. This is due primarily due to the following we have develop in this types of projects. However, a lot of general contractors from Inverness to Machesney Park, IL, don’t know that NY Engineers is also a top contender for anyone in search of HVAC Contractor in or near Chicago.

The search for energy efficient buildings involves energy efficient HVAC system design. This can include systems for domestic water heating, architectural enclosure, HVAC, lighting, and vertical transportation. The loads for your HVAC systems will come primarily from 5 different bases including lighting (cooling), your building envelope (cooling and heating), ventilation (cooling and heating), equipment for program use (cooling) and occupancy (cooling).
The ventilation load will certainly be a function of either the mechanisms necessary to be able to introduce it in a space and control contaminant concentration or the amount of persons who will occupy the place. In virtually all climates inside the southwestern and eastern parts of the US, to minimize outside air-flow can save energy whenever the surface air is either warm and humid or very cold.
Governing the ventilation rate will be based on occupancy which is called a kind of demand control ventilation. This really is a common type of energy conservation tatic that is used for spaces with occasional or crowded occupancy. Having heating and cooling loads dropped as low as possible can be carried out by using an increased performance building envelope, occupancy sensors, and high performance lighting that utilize daylight response of lighting controls.

Chicago HVAC Engineering services versus HVAC Techs

If you’ve ever thought about the difference between a HVAC Engineers versus HVAC Technicians, then please read on:

HVAC engineers are definitely the people who manage installing of air conditioner systems for both residential and commercial buildings. They spend plenty of their day in offices doing advanced level management and preparation of installations nonetheless they do also stop by job sites every once in awhile.

In contrast, HVAC technicians often do more of the hands-on work  that deals with repair and maintenance. A HVAC technician may work together with an engineer to accomplish a few of the installation work, specifically on smaller jobs. Generally HVAC technicians do far more travel and may spend lots of time identifying leaks, changing filters, doing recharges or getting rid of old and outdated systems that use old refrigerants.

HVAC engineers may have the chance to make more decisions about systems that are used, plus they are the folks that would offer assistance with probably the most sensible refrigerants and which systems would best suit a greater building. In the trade, there is some conflict between ‘the suits’ and ‘the ones that will get their hands dirty’, but both jobs require an excellent understanding of how air conditioning does work. Lately a lot of individuals have been checking out the NY Engineers website looking for HVAC Repair Chicago Il. However, the focus of our firm is to become the top option for anyone seeking a HVAC Chicago and or any of our other services including Sprinkler Design Engineering services.

Electrical Engineers Explain Electric Vehicle Charging Stations

Fire Protection Engineer Certification

Electrical engineers have noted that electric vehicles are gaining a larger share of the automotive market, while also becoming more affordable. Environmental awareness has become a key driving force in EV adoption among consumers, and businesses are realizing they can attract these drivers by offering EV charging stations. Some government programs such as the California Zero Emission Vehicle (ZEV) rule are requiring automakers to offer more environmentally friendly vehicles.

The emissions reduction potential of EVs is significant because they can run with electricity generated by wind turbines or solar panels. Even if an EV relies on a power grid where most electricity comes from fossil fuels, there is a reduction of emissions: power plants use fossil fuels much more efficiently than the combustion engines on cars.

Electric Vehicles and Charging Time

Plug-in electric vehicles (PEVs) obtain most or all of their power from electricity supplied by the power grid. Plug-in hybrid electric vehicles (PHEVs) offer 3-4 miles per kWh of charge, as a rule of thumb, although this may vary depending on driving habits.

There are two main factors that influence battery charging time:

  1. Battery capacity, typically measured in kilowatt-hours (kWh). It typically ranges from 4 to 90 kWh, depending on the type of vehicle.
  2. Charging station features: capacity and limit charging speed.

The rate at which the car can accept charge is measured in kilowatts (kW). Each vehicle has its own maximum rate based on its internal charging capacity, and may or may not have a separate DC charging port.

Electric Vehicle Charging Stations

EV charging stations can be classified into three types, based on their charging method:

  1. Level 1 charging
  2. Level 2 charging
  3. DC fast-charging

Level 1 charging uses the standard 120 V AC power supply and offers 2 to 5 miles of range per hour (RPH). Depending on the car and battery specifications, it takes 8-20 hours to add 40 miles of range. Level 1 charging typically uses a three-pronged NEMA 5-15 standard household plug.

Level 2 charging uses a residential or commercial 208-240V power supply and the vehicle’s onboard charger, offering 10 to 30 miles of range per hour. Level 2 charging is characterized by protecting the user from electrified components: commercial units are hard-wired and free from exposed power outlets, only establishing an electric current once connected to the vehicle.  These stations can be installed as a stand-alone system or in a network configuration.

DC fast charging was previously called level 3 charging, requiring 208-480V three-phase power. The charger converts the power input to DC and supplies it directly to the battery. DC fast charging offers up to 100-200 miles of range per hour and takes 15 to 45 minutes to charge from 0 to 80 percent, depending on the vehicle.

Level 2 charging works best where parking times are longer than an hour, which includes overnight charging at homes or hotels, workplace charging or fleet charging. Level 2 charging is also feasible during dining, sports, recreation and shopping.

DC fast charging best serves businesses and locations where the average parking time of the customer is less than one hour. It can be used to complement Level 2 charging. However, take note of the consequences when using the wrong type of charger: a LV2 charger offers a bad user experience for a short parking time, and using DC fast chargers where the vehicles will stay parked for long represents a waste of resources.

Electrical Engineers Detail Relevant Codes and Regulations

In some cities, the following provisions apply for electric vehicle charging in garages and parking lots:

  1. Conduit and solar panel capacityfor up to 20% of newly created parking stalls. This applies for garages and parking lots.
  2. Attachment plugs, EV connectors and inlets must be labeled for their intended purpose.
  3. EV supply equipment must be provided with an interlock.
  4. Overcurrent protection for feeders and branch circuit supplying EVs shall have a rating of at least 125% of maximum load.
  5. The EV supply equipment shall be located to permit direct connection to the vehicle itself.

Conclusion

AC Level 1 and 2 charging provide AC power to the vehicle, where the vehicle’s onboard charger converts AC to DC power needed to charge the batteries. Planning, including site assessment and selection considerations, and assessing electrical needs and availability, is critical for functional, aesthetically pleasing and cost-effective installations that can meet present and future needs. If you need any help in understanding these concepts, it’s best to confer with experienced electrical engineers.
