Recently huge crowds have been stopping by the New York Engineers website searching for Electrical Engineering in or near the Chicago area. This is due because of the following we have develop in this kind of work. However, a lot of building managers from Carpentersville to Phoenix, are not aware that NY-Engineers.Com is also a top contender for anyone searching for HVAC Chicago.

The pursuit of energy efficient buildings involves energy-efficient HVAC system design. This may include systems for domestic water heating, architectural enclosure, HVAC, lighting, and vertical transportation. The loads for that 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 certainly be a function of either the devices required to be able to introduce it into a space and control contaminant concentration or the quantity of people that may be in the room. In the majority of climates within the southwestern and eastern regions of the united states, to reduce outter air-flow will save energy whenever the

outside air is either humid and warm or very cold.
Managing the ventilation rate is going to be dependant upon occupancy which is called a form of demand control ventilation. This really is a everyday sort of energy conservation strategy that is utilized for homes with intermittent or heavy occupancy. Having heating and cooling loads dropped as low as possible can be achieved through the use of a very high performance building envelope, occupancy sensors, and performance lighting that apply daylight response of lighting controls.

Chicago HVAC Engineering services versus HVAC Technicians

If you’ve ever discussed the distinction between a HVAC Technician vs HVAC Engineers, then continue reading:

HVAC engineers are the people who watch over installing of air conditioning systems both for residential and commercial buildings. They spend a great deal of their day in offices doing higher-level organization and arranging of installations but they do also visit job sites every once in awhile.

But, HVAC technicians in Chicago have a tendency to do a lot of the hands-on work with repair and maintenance. A HVAC technician may work together with an engineer to do some of the installation work, especially on smaller jobs. Generally HVAC techs do a lot more travel and may even spend considerable time identifying leaks, changing filters, doing recharges or getting rid of old and outdated systems that utilize old refrigerants.

HVAC engineers could possibly have the opportunity to make more decisions about systems that are used, and they also are definitely the people who would offer assistance with one of the most sensible refrigerants and which systems would best suit a greater building. In the trade, there is certainly some conflict between ‘the suits’ and ‘the ones that will get their hands dirty’, but the two jobs do require an effective understanding of how air conditioner really works. Nowadays huge crowds have been crawling our sites searching for things like HVAC License Chicago. Nevertheless, the goal of our organization is to become the number one choice for anyone looking for a HVAC Chicago and or any of our other services including Protection Engineering services. We ask that anybody looking for additional information about our Heating & Air Conditioning (HVAC) Engineering Firm in Chicago Illinois visits at our blog…

Electrical Engineers Explain Electric Vehicle Charging Stations

Construction Engineering Companies

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.
