In recent times Many people have been taking a look at our site in search of Electrical Engineering in Chicago. This is due primarily due to the reputation we have built in this kind of work. With that said, a lot of builders from Highwood to Woodridge, Illinois, are not aware that NY Engineers is also the ideal choice for anyone in search of HVAC Chicago, IL.

The quest for cost effective buildings involves cost effective HVAC system design. This may include systems for lighting, architectural enclosure, domestic water heating, HVAC, and vertical transportation. The loads for your HVAC systems will come primarily from 5 different bases 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 function of either the mechanisms necessary in order to introduce it right into a space and control contaminant concentration or the quantity of individuals that may occupy the area. In virtually all climates inside the southwestern and eastern regions of the usa, to minimize outter air flow can save energy whenever the

outside air is either humid and warm or very cold.
Governing the ventilation rate is going to be dependant on occupancy which is referred to as a kind of demand control ventilation. It is a common type of energy conservation strategy which is used for buildings with occasional or dense occupancy. Having cooling and heating loads reduced as low as possible can be carried out through the use of a high performance building envelope, occupancy sensors, and high performance lighting that apply daylight response of lighting controls.

Chicago HVAC Engineers vs HVAC Techs

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

HVAC engineers will be the people who oversee setting up of air conditioner systems for both commercial and residential buildings. They spend plenty of their day in offices doing higher level management and planning of installations nevertheless they do also see job sites every so often.

But, HVAC technicians have a tendency to do a lot of the hands-on work with maintenance and repair. A HVAC tech may work together with an engineer to do a few of the installation task, specifically for smaller jobs. In general HVAC techs do a lot more travel and could spend time and effort changing filters, identifying leaks, doing recharges or decommissioning old and outdated systems that utilize old refrigerants.

HVAC engineers may have the ability to make more decisions about systems that are employed, and so they are the folks that would offer assistance with the most sensible refrigerants and which systems would be perfect for a greater building. In the trade, there is some competition between ‘the suits’ and ‘the ones which get their hands dirty’, but both jobs do require an excellent familiarity with how air conditioner is proven to work. Lately many individuals have been getting to our sites searching for HVAC Supply Chicago. With that said, the focus of our organization is to become the top option for anyone seeking a HVAC Companies in or near Chicago and or any of our other services including Sprinkler Design Engineering services.

Electrical Engineers Explain Electric Vehicle Charging Stations

Mechanical Engineering Requirements

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.
