What’s so well known is that NY-Engineers.Com is more than likely your top choice for anyone looking for a fire sprinkler design engineering in Lake Bluff. At New York Engineers our staff has many years of experience designing fire protection and sprinkler systems from Cheektowaga to Lindenhurst, NY. Now, from our Chicago office we are helping general contractor and building owners in Lake Bluff design the fire protection and sprinkler systems they need.

The possibility of a building burnt down due to fire is a sight that no one wants to have. That is the reason fire protection engineers are hired before a building or apartment is created. In case you are wondering who needs fire protection engineer, then the first name you should know is the architect of the building. Exactly like an architect is very important to make sure that the design of the property is perfect and protected from all ends; a fire protection engineer helps to ensure that the property is protected from possible likelihood of fire.

Having prompt answer in the firefighting experts is acceptable but won’t it be fantastic if a fire never happened? You must think about “what if” as opposed to feeling the horrendous experience of your building catching on fire. Fire protection engineers glance at the style of the construction first and then plan the escape paths to be taken during a fire. Furthermore, they are responsible for adding several fire protection things in and outside the structure. Water hoses and pipes connected to the main water tank, and checking the condition of the fire extinguishers are some of the duties which the fire protection engineer performs when they are hired.

Difference Between Lake Bluff Fire Sprinkler Tech versus Protection Engineers

The Society of Fire Protection Engineers features a specific definition of Fire Technology versus Protection Engineers. The two positions call for a solid education in fire technology and skill being a firefighter typically.

The engineers use principles to make use of systems and methods setups in various structures that really help protect folks and things from injury during fires. Engineers study possibilities of where biggest fire threats lie and where you can put protection including sprinklers. They ensure that the use of residences as well as any materials in them are made to keep hazards to a minimum.

Engineers will likely manage the fitting and upkeep of alarm systems, smoke detectors, and may do investigations of fires after it happens. This can help them stop such incidences from happening in the foreseeable future.

This particular title uses scientific principles to assist increase the safety of men and women in homes and offices. A fire technician activly works to carry out the testing and upkeep of the systems which were arranged and laid out from the engineers.

These individuals also needs to possess the best schooling and firefighting training to operate in the field. They may work to aid add sprinklers and fire alarm systems however they do not plan the design of the systems much like the engineers do. There is only so much you can save this page if you would like additional details about fire protection engineering services in Lake Bluff by NY-Engineers.Com you should check out at our Chicago Engineering Reports blog.

Advantages of Electronically Commutated Motors in Electrical Engineering

HVAC Engineers Near Me

Electronically commutated motors (ECMs) can achieve significant energy savings in electrical engineering applications where fractional horsepower is required. Although NEMA Premium Efficiency motors with variable-frequency drives provide the most efficient solution to drive equipment above 1 hp, induction motors are outclassed by ECMs as the rated horsepower is reduced.

What is an Electronically Commutated Motor?

Although ECMs are designed to run with an AC power supply, it is important to note they are actually direct-current motors with permanent magnets on their rotor. Unlike conventional DC motors, which create a rotating magnetic field with a combination of brush contacts and slip rings, ECMs achieve the same effect with a voltage rectifier and an electronic control circuit. As a result, the friction and sparks associated with brush contacts are eliminated, and this is one of the reasons why ECMs are so efficient. They also have a longer service life than brushed motors, since the wear associated with sparks and friction is eliminated. Compared with other common types of fractional horsepower motors, ECMs are the top choice in terms of efficiency:

  • Shaded-pole motors are very common and more affordable, but their efficiency is very poor, going below 20% in some cases.
  • Permanent-split capacitor (PSC) motors have an average efficiency of 40%, which means they outclass shaded-pole motors. In terms of efficiency, they are an intermediate option between shaded-pole motors and ECMs.
  • ECM efficiency is normally above 60%, which means they consume one-third of the energy used by shaded-pole motors on average.

ECMs can also be manufactured with built-in speed control circuits, allowing them to operate at reduced speed without relying on an external VFD. It is also important to note that ECMs do not suffer a drastic reduction in their efficiency when operating below rated RPM. Fixed-speed ECMs are also available for applications where speed control is not necessary.

Electronically Commutated Motors in Electrical Engineering Applications

ECMs are normally the most efficient option in fractional horsepower applications, but they tend to deliver the highest savings when used in air-conditioning and refrigeration systems. Being more efficient that shaded-pole and PSC motors, they also dissipate less heat, and the reduced heating effect helps AC and refrigeration systems operate more efficiently. This effect applies for all air-conditioning or refrigeration components that are found inside the conditioned space, such as air handlers and evaporators.

As an example, assume a cold-storage room has an evaporator unit with five shaded-pole motors, consuming 900W each. They are replaced with ECMs that only consume 300 W each.

  • 600 W are saved per motor, for a total of 3,000 W.
  • However, these 3,000 W are also subtracted from the refrigeration load. If the system operates with a coefficient of performance of 3, an extra 1,000 W of electric power are saved.
  • In other words, this upgrade saves 3 kW in motor power and 1 kW thanks to refrigeration load reduction.

Keep in mind this is just a simple example, and each electrical engineering project requires a detailed analysis to know the exact savings. However, the heating reduction benefit applies for all cases where ECM motors are deployed in air-conditioned or refrigerated locations.

The brushless design of ECMs makes them quieter than their less efficient counterparts, which also provides a comfort advantage. In business applications, the silent operation of ECMs helps employees concentrate better. ECMs are also lighter than other types of fractional horsepower motors, which makes them easier to install.

Electronically Commutated Motors in Ventilation Systems

As previously stated, shaded-pole and PSC motors are inefficient. Also, three-phase motors with VFDs are impractical for fractional horsepower applications, unable to offer the efficiency that characterizes them in larger systems. Ventilation systems represent an excellent opportunity to deploy ECMs, for two main reasons:

  • Fans with fractional horsepower are common, which means they are often driven by shaded-pole or PSC motors.
  • Many fans have intermittent operation, which represents a chance to use ECMs running at reduced speed. For example, running a fan 80% of the time saves 20% of the energy, while running it at 80% speed saves nearly 50%.

ECMs are a highly recommended upgrade for furnace fans, since they can achieve a much more uniform temperature distribution with their speed control, in addition to offering the energy savings that characterize them.

Payback Period of ECM Upgrades

Like with many energy efficiency measures, the financial benefit of an ECM upgrade changes depending on project conditions. The project payback period can only be calculated with precision after a detailed analysis by a professional energy consultant, but in general the following results can be expected:

  • Replacing shaded-pole motors normally yields a faster payback period than replacing PSC motors, since the efficiency gain is higher. Of course, there can be exceptions; replacing a PSC motor that is used frequently may yield higher savings than upgrading a shaded-pole motor that is only used moderately.
  • ECMs can also be an attractive option in appliances that require speed control. Other types of motors may suffer a drastic efficiency reduction at partial speed.
  • As previously mentioned, the energy savings are higher when ECMs are deployed in air-conditioned or refrigerated spaces.

The financial return of an ECM upgrade can also be enhanced if there are incentive programs at the project’s location. The incentive is calculated based on yearly energy savings, at a rate of $0.16/kWh.

Conclusion

Electronically-commutated motors (ECMs) can achieve significant energy savings in fractional horsepower applications, especially when they replace shaded-pole motors. However, like with any energy efficiency upgrade, professional guidance is highly recommended when defining the project scope and specifications.

When upgrading to ECMs, the return on investment is higher in some cases, and it others the payback period may be too long to justify the upgrade. Ideally, upgrades should focus on where the highest return is obtained from each dollar spent upfront.
