As of late huge crowds have been taking a look at our site looking for Value Engineering near Chicago. That is due primarily due to the reputation we have built in this kind of work. However, many general contractors from Chicago Ridge to Palos Hills, Illinois, are not aware that NY-Engineers.Com is also a top choice for anyone in search of HVAC Chicago.

The quest for energy-efficient buildings involves cost effective HVAC system design. This will likely include systems for lighting, architectural enclosure, domestic water heating, HVAC, and vertical transportation. The loads for your HVAC systems may come primarily from 5 different places including lighting (cooling), the property envelope (cooling and heating), ventilation (cooling and heating), equipment for program use (cooling) and occupancy (cooling).
The ventilation load is a purpose of either the devices required in an attempt to introduce it right into a space and control contaminant concentration or the quantity of folks which will occupy the area. In the majority of climates in the southwestern and eastern regions of the US, to reduce outside ventilation will save energy whenever the

outside air is either humid and warm or very cold.
Governing the ventilation rate will probably be dependant upon occupancy which is known as a type of demand control ventilation. This can be a everyday sort of energy conservation policy that is used for rooms with occasional or heavy occupancy. Having cooling and heating loads reduced to a minimum can be accomplished by using a higher performance building envelope, occupancy sensors, and performance lighting that uses daylight response of lighting controls.

Chicago HVAC Engineers versus HVAC Technicians

When you have ever considered the difference between a HVAC Engineers vs HVAC Engineers, then please read on:

HVAC engineers are definitely the people who watch over the installation of air cooling systems for both residential and commercial buildings. They spend plenty of their work in offices doing higher-level organization and arranging of installations nonetheless they do also stop by job sites from time to time.

In contrast, HVAC technicians have a tendency to do a lot of the hands-on work with repair and maintenance. A HVAC tech may work together with an engineer to complete a number of the installation work, specifically on smaller jobs. Generally speaking HVAC techs do a lot more travel and may even spend a lot of time identifying leaks, changing filters, doing recharges or decommissioning old and outdated systems that utilize old refrigerants.

HVAC engineers might have the ability to make more decisions about systems that are being used, plus they would be the individuals who would offer advice about one of the most sensible refrigerants and which systems would be perfect for a larger building. In the industry, there is some challenge between ‘the suits’ and ‘the ones that get their hands dirty’, but the two jobs require a great expertise in how air-con works. In recent times many people have been checking out our sites looking for HVAC Chicago Illinois. Nevertheless, the goal of our company is to become the number one choice for anyone looking for a HVAC Contractor in or near Chicago and or any of our other services including MEP Engineering Engineering services. We ask that anybody searching for additional info about our Heating Cooling Air Conditioning Furnace (HVAC) Engineering Firm in Chicago Illinois stops by at our Value Engineers blog.

Using Proper MEP Engineering to Protect Water Booster Pumps from Cavitation

What Do Architectural Engineers Do

Booster pumps play a very important role in ensuring a continuous water supply. In the absence of a booster system, most buildings only get a reliable water supply for the first five floors. For this same reason, keeping booster pumps under optimal operating conditions is a very important part of MEP engineering, and one of the main causes of impeller failure is an hydraulic phenomenon called cavitation. This article will provide an overview of cavitation and how it can be prevented.

What is Cavitation?

Everyone knows that water can be boiled with heat, turning it into vapor. However, low pressure can also vaporize water, and this can happen inside a pump if water is not supplied with enough pressure at the intake. When the pressure of a fluid drops below a critical value called the vapor pressure, small bubbles form in the flow, and these bubbles collapse violently once pressure increases again – the phenomenon is called cavitation, because the bubbles are cavities in the fluid.

You may be wondering how a pump reduces fluid pressure, when its actual purpose is to increase it. The answer can be explained with Bernoulli’s principle, which states that a fluid loses pressure as it speeds up or as it rises to a higher elevation. Water speeds up at the pump suction, and its pressure drops momentarily before being increased.

One bubble forming and collapsing does not cause major issues, but consider that thousands are continuously forming and imploding when a pump has severe cavitation issues. The combined shockwaves of all these bubbles gradually erode the pump impeller. When removed, the impeller blades will seem to have corroded, even though cavitation does not involve any chemical processes.

Other than impeller erosion, cavitation has many negative consequences in water booster pumps and other similar systems:

  • Vibration: The ongoing formation and collapse of bubbles not only wears down the impeller. The resulting shockwaves also shake the impeller, inducing vibrations in the entire shaft, with the potential to damage other system components. Seals and bearings are especially vulnerable to vibration.
  • Noise: Cavitation is very noisy due to the imploding bubbles. For a person close to the affected pump, it may sound like there are small rocks or marbles are being pumped along with water.
  • Decreased performance: Cavitation represents wasted energy, and this can be reflected as a reduction in flow or discharge pressure. A sudden drop in pump performance without an evident reason may indicate cavitation.

Preventing Cavitation With Adequate MEP Engineering

The technical specifications for pump manufacturers typically include a value called the Net Positive Suction Head (NPSH) required, which can be defined as simple terms as the minimum water head required at the pump suction for normal operation. If the actual head is above the NPSH required, no cavitation occurs.

In theory, cavitation can be prevented by increasing the suction pressure or by reducing the speed of water as it flows through the pump impeller. In practice, there are many ways to accomplish this effect.

  • Reduce pump speed: Cavitation is less likely at lower RPM values, so a booster pump can be slowed down with a variable frequency drive (VFD), as long as the system continues to meet the pressure and flow requirements in the local plumbing code.
  • Install the pump at a lower level: Static water pressure is higher at the lower levels of a building, so installing it at the lowest elevation possible reduces the chance of cavitation.
  • Reduce temperature: The critical pressure at which cavitation occurs increases as fluid temperature increases. If water must be pumped and heated, make sure the pump is installed upstream from the water heater.
  • Selecting the right pump: Many cavitation issues can be attributed to poor pump selection, and the issue disappears when a pump that matches the application is used.

The best solution for cavitation is not allowing it to occur in the first place, and this can be accomplished by working with qualified MEP engineering professionals from the start of a project. Modifying actual projects is far more expensive and time consuming than editing construction plans and specifications. A high-level professional design will not only prevent cavitation, but also optimal equipment capacity, energy efficiency and local code compliance.
