Lately Hundreds of individuals have been stopping by our site searching for Fire Protection Engineering near the Chicago area. That is due because of the following we have develop in this types of projects. However, a lot of building managers from Glencoe to Tinley Park, Illinois, don’t know that NY Engineers is also a top choice for anyone searching for HVAC Chicago.

The pursuit of power efficient buildings involves energy efficient HVAC system design. This will include systems for HVAC, lighting, architectural enclosure, domestic water heating, and vertical transportation. The loads for the HVAC systems can come primarily from five 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 might be a function of either the mechanisms required in order to introduce it right into a space and control contaminant concentration or the number of persons which will occupy the room. In the majority of climates within the eastern and southwestern regions of america, to lessen outter air-flow helps you to save energy whenever the outer air is either humid and warm or very cold.
Managing the ventilation rate will likely be determined by occupancy which is called a form of demand control ventilation. It is a everyday sort of energy conservation approach which is used for buildings with irregular or dense occupancy. Having cooling and heating loads dropped to a minimum can be accomplished by utilizing a higher performance building envelope, occupancy sensors, and performance lighting that apply daylight response of lighting controls.

Chicago HVAC Engineers versus HVAC Techs

When you have ever thought about the difference between a HVAC Engineers versus HVAC Technicians, then read on:

Chicago HVAC engineers are the people who run installing of air-con systems both for commercial and residential buildings. They spend lots of their time in offices doing more impressive range organization and preparation of installations nonetheless they do also visit job sites every once in awhile.

In contrast, HVAC technicians have a tendency to do a lot of the hands-on work with maintenance and repair. A HVAC technician may assist an engineer to complete several of the installation task, particularly for smaller jobs. In general HVAC technicians do far more travel and might spend lots of time identifying leaks, changing filters, doing recharges or decommissioning old and outdated systems which use old refrigerants.

HVAC engineers could have the ability to make more decisions about systems that are being used, and they also are the individuals who would offer assistance with probably the most sensible refrigerants and which systems would be perfect for a larger building. In the industry, there is certainly some challenge between ‘the suits’ and ‘the ones which get their hands dirty’, but both jobs do require a great familiarity with how air conditioner is proven to work. As of late many people have been reading the New York Engineers site searching for things like HVAC Companies Chicago. With that said, the goal of our firm is to become the to go to firm for those searching for a HVAC Firm in or near Chicago and or any of our other services including Architectural Engineering Engineering services. We ask that everyone searching for more details about our Heating and Air Conditioning (HVAC) Engineering Firm in Chicago Illinois checks out at our Mechanical Engineers blog!

Electrical Engineers Explain Electric Vehicle Charging Stations

Is There A Demand For Mechanical Engineers In The Future

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.
