Mechanical Engineers Say Proper Ventilation is Crucial for Your Small Business

2018-10-26T09:39:38+00:00

Engineers Explain How Good Ventilation Helps Your Business We’ll start with a fact that often startles people: (indoor air quality is a major health threat in the country).  According to the U.S. Environmental Protection Agency, the air quality inside buildings is often 3 to 4 times worse than the air outside. This goes against what most people think air pollution is like— fumes from cars and smoke stacks casting dark clouds over cities.  Heavy wall insulation, tightly fitted, non-opening windows ( Window Efficiency ), and commercial synthetic carpeting in modern buildings allows for the rapid build-up of contaminants inside without the chance to escape. Proper ventilation in your business that was designed by a licensed mechanical engineer(Licensed Mechanical Engineer ), is a key [...]

Engineers Develop Ways to Ventilate Your Home

2018-09-25T15:38:05+00:00

Why ventilate? For centuries homes weren’t ventilated, and they did all right, didn’t they? Why do we need to go to all this effort (and often considerable expense) to ventilate houses today?  Engineers have developed several reasons that ventilation is more important today than it was long ago. Most importantly, houses 100 years ago were leaky. Usually they didn’t have insulation in the walls, so fresh air could easily enter through all the gaps, cracks, and holes in the building envelope., the building materials used 100 years ago were mostly natural products that didn’t result in significant off gassing of volatile organic compounds (VOCs), formaldehyde, flame retardants, and other chemicals that are so prevalent in today’s building materials, furnishings, [...]

Engineers Test “CHP” – Combined Heat and Power

2018-09-04T12:40:22+00:00

Figure 1. Self Sufficient Home with Combined Heat and Power Combined Heat and Power (CHP) Engineers combined heat and power (CHP) systems, also known as cogeneration, generate electricity and useful thermal energy in a single, integrated system. CHP is not a technology, but an approach to applying technologies. Heat that is normally wasted in conventional power generation is recovered as useful energy, which avoids the losses that would otherwise be incurred from separate generation of heat and power. While the conventional method of producing usable heat and power separately has a typical combined efficiency of 45 percent, CHP systems can operate at levels as high as 80 percent. Some micro-CHP technologies use mechanical engines, such as internal combustion [...]

  Material Scientist Ponder What to Do With Used EV Batteries  As electric vehicles become mainstream, mechanical engineers and chemical engineers are trying to address the big environmental question: what do we do with the used lithium-ion batteries? The batteries used in electric cars are physically large, last 8 to 10 years, and will account for 90 per cent of the lithium-ion battery market by 2025.  This will increase lithium demand fourfold, and more than double the demand for cobalt — two of their essential elements.  The price of cobalt has already risen by more than 80 per cent in 2018.   Most expert Material Scientists agree that a replacement hybrid car battery can range from $1,000 to more than $6,000.  The [...]

Semiconductor Worldwide: Samsung Takes Over

2018-06-22T11:44:20+00:00

Samsung topples Intel as top dog semiconductor market share  Gartner beancounters say price rises driven by memory shortages propelled Samsung into the lead based on semiconductor vendor revenue, vaulting past Intel and its CPUs. The largest memory supplier, Samsung Electronics, gained the most semiconductor market share and took the No. 1 position from Intel – the first time Intel has been toppled since 1992. Memory accounted for more than two-thirds of all semiconductor revenue growth in 2017, and became the largest semiconductor category.  DRAM prices rose 44 per cent from 2016 to 2017, and NAND flash prices went up 17 per cent year-over-year for the first time.

Window Energy Efficiency: Solar Heat Gain and Visible Transmittance

2018-08-22T11:55:28+00:00

Conduction and Radiation of Thermal Energy In my last blog post, I wrote about the conduction and radiation of thermal energy through windows and the thermal transmittance value, called the U-Factor, that characterizes that heat transfer.  The U-factor is useful in evaluating window performance and making wise decisions when specifying components for a building, but it is only one piece of the puzzle.  The National Fenestration Research Council (NFRC) mandates a second value alongside U-factor in its certification process, called the Solar Heat Gain Coefficient (SHGC).  SHGC represents the ability of a window to resist heat gain from radiation, like the sunlight in Figure 1.  This is obviously a challenge, given that the entire point [...]

Window Energy Efficiency: Thermal Transmittance

2018-08-22T11:46:58+00:00

Figure 1: Windows catching sunlight By Magda S [FreeImages.com Content License] In our last blog post, I wrote about the thermal resistance (R-value) and transmittance (U-factor) of insulation and windows.  The R-value represents how well a material prevents heat transfer through its thickness, and U-factor is its inverse, representing how much heat a material will conduct through.  These values are fairly simple to calculate for most building materials materials like the bricks and panels in Figure 1, as they primarily experience only conductive heat transfer.  Windows are a more challenging proposition, however, since the heat transfer through them includes radiation across the entire spectrum, not just the visible light we see and the infrared we feel.  In [...]

Energy Efficiency in Building Materials, Insulation and Windows

2018-04-04T09:48:28+00:00

Figure 1: FLIR image of two houses showing energy loss. Colors towards red on the scale indicate warmer surfaces and more energy loss. The basic principle behind thermal insulation is simple to understand.  The harder it is for heat to travel through a material, the better insulator that material will make.  In this blog, I’m going to take a look at how that effectiveness is quantified, after a brief review of the three methods of heat transfer.  The building and construction industry use a ratio called the R-factor to indicate how well a building material can insulate a space.  Also called the thermal insulance or thermal resistance, a higher R-value indicates a more effective insulator. Heat Transfer Methods There are [...]

Thermal Expansion in a Glass and Aluminum Window: Part 2

2018-02-20T13:29:14+00:00

Figure 1: Simplified model of an aluminum-glass window   In last week’s blog, Thermal Expansion in a Glass and Aluminum Window: Part 1, we introduced the basic concept of thermal expansion in solid materials.  Since CTE mismatch can impose extremely high stress, during mechanical engineering design one must consider the temperature exposure and expansion or contraction of a material.  In order to help the read gain insight, we used a simplified aluminum-framed window to demonstrate that a hot summer day would be enough to shatter glass if the window wasn’t equipped with a flexible gasket between the frame and the glass.  For this entry, we utilize a finite element analysis (FEA) to elucidate the stress effects caused by both high and [...]
