A Guide to Finding the Best Infrared Heating Pads Infrared technology provides heat that doesn’t burn your skin like traditional electric heating pads. Infrared heating mats provide deeper and long-lasting pain relief over conventional heating pads. The Benefits of Infrared Heating Pads • Blood circulation enhancement • Pain reduction • Joint inflammation and stiffness relief • Skin cell revitalization These are only a few benefits of this heating technology that works much like the sun, which…

Did you know that "insulation reduces average home heating and cooling costs by around 20%". Many parts of the country have changed in temperature that affects the comfort in homes and workplaces. Season to season, these temperatures drive people crazy. In cold weather, this means it keeps the warm air inside and in the hot weather, it prevents hot air from coming in. Insulation helps maintain comfort no matter where you are. The best types would be the ones that keep the hot air out in the…

Energy performance of the original house is not terribly bad but not satisfied, either. It wastes a huge amount of energy in cooling the living area. Strategies of achieving better passive heating and cooling will be illustrated as following. Reducing cooling energy consumption will be emphasized in designing the new house. The original orientation (315 degrees with living room faces south-west) resulted in excessive heat gain during summer, especially in the afternoon, and insufficient heat…

One of the challenges chemical engineers face with ethane cracking in a tubular reactor is the formation of a detrimental coke layer on the inner tube wall. According to the article [1], the mechanism is mainly induced by degradation of hydrocarbons to an aromatic structure by condensation and dehydrogenation. This brings about a bunch of various effects described in the article. In my model built during the term project, I decided to introduce a new effect of reducing the diameter, consider…

Maciej Szwoch Chm 131-005 5/5/18 Writing Assignment Figure 1 [This diagram shows at what temperatures/pressures water changes phases. As shown in Figure 1 (“Interactive Student Tutorial”) above water turns into a gas at 100 degrees Celsius. At 0 degrees Celsius and below it becomes a solid. This diagram makes it easy to see that the energy needed (temperature) to change phases greatly increases] Molality Molality is the number of Moles of solute divided by kilograms of solvent (Tutapoint…

Introduction Heat exhaustion is a condition caused by exposure to extreme heat. Heat exhaustion means that your body is too hot. Your body cools itself by sweating. When your body cannot cool down, you could develop heat exhaustion. Untreated heat exhaustion could lead to heat stroke. Heat stroke can be deadly. Elderly adults have a greater risk for heat exhaustion than younger adults. Other adults who may be at higher risk are those who are overweight, have high blood pressure, or have heart…

You asked the following question: “I have an existing building with a wet system. The owner is installing a walk-in cooler that will be maintained between 33°F and 39°F with a thermostat. The top of the cooler is approximately 10 feet below the ceiling so I will need to drop sprinklers into the cooler. Are the sprinklers I am dropping into the cooler required to be dry pendent sprinklers or are standard pendent sprinklers acceptable because it is being maintained above 32°F?” In response to…

Considering A Whole-Home Evaporative Cooler? Know The Advantages And Disadvantages An evaporative cooling system will use air outside your home to cool the air inside your home by having it pass over a moistened pad. It can cool down your home from anywhere between 15-40°F, making it an acceptable way to keep your home cool in the summer. That said, the unit has its own advantages and disadvantages over central air conditioning. Consider the following things when researching a whole-home…

Background Research Focused, hard work is the real key to success. Keep your eyes on the goal, and just keep taking the next step towards completing it. If you aren't sure which way to do something, do it both ways and see which works better (John Carmack). The question, does the brand of insulation affect how cold the temperature is in a model house, is yet to be determined. The brand of insulations are, Green Fiber, Owens Corning, InsulFoam, and Johns Manville. The hypothesis is, If a model…
