As of late huge crowds have been browsing the NY-Engineers.Com website looking for Electrical Engineering in or near 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 Glenview to Park Ridge, Illinois, don’t know that NY-Engineers.Com is also the ideal choice for anyone searching for HVAC Chicago.

The quest for cost effective buildings involves power efficient HVAC system design. This can include systems for lighting, architectural enclosure, domestic water heating, HVAC, and vertical transportation. The loads for the HVAC systems will come primarily from 5 different places 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 machines necessary so as to introduce it into a space and control contaminant concentration or the amount of people that will use the space. In nearly all climates from the southwestern and eastern regions of america, to lower outter air-flow helps save energy whenever the

outside air is either warm and humid or very cold.
Governing the ventilation rate will be dependant upon occupancy which is known as a variety of demand control ventilation. It is a common type of energy conservation approach that is used for rooms with irregular or dense occupancy. Having cooling and heating loads reduced as low as possible can be achieved by making use of a higher performance building envelope, occupancy sensors, and performance lighting that apply daylight response of lighting controls.

Chicago HVAC Engineers versus HVAC Techs

If you have ever wondered about the difference between a HVAC Technician versus HVAC Technicians, then continue reading:

Chicago HVAC engineers will be the people who supervise setting up of air cooling systems for commercial and residential buildings. They spend a lot of their time in offices doing more impressive range management and planning of installations however they do also go to job sites from time to time.

But, HVAC technicians tend to do a lot of the hands-on work  that deals with maintenance and repair. A HVAC technician may work with or for an engineer to accomplish several of the installation task, especially on smaller jobs. On the whole HVAC technicians do far more travel and may even 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 opportunity to make more decisions about systems that are used, and they would be the folks that would offer advice about by far the most sensible refrigerants and which systems would be perfect for a much bigger building. In the industry, there exists some challenge between ‘the suits’ and ‘the ones that get their hands dirty’, but the two jobs require an excellent understanding of how air conditioner really works. Nowadays a lot of individuals have been checking out the NY-Engineers.Com site searching for things like HVAC West Chicago Il. However, the focus of our firm is to be the number one choice for anyone looking for a HVAC Firm in Chicago and or any of our other services including Construction Engineering Engineering services. We ask that those searching for additional info about our Air Conditioning, Heating & Cooling (HVAC) Engineering Firm in Chicago Illinois stops by at our blog.

Electrical Engineers Explain Electric Vehicle Charging Stations

What Do Mechanical Engineers Do

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.
