Solar thermal energy

Thermal energy strorage Thermal Energy Storage is the temporary storage of high or low temperature energy for later use, bridging the gap between requirement and energy use. The storage cycle might be daily, weekly or seasonal depending on the system design requirements, and whilst the output will always be thermal, the input may be thermal or electrical. Principle 1) Sensible Heat Storage Heating a liquid or solid, without changing the phase: This method is called sensible heat storage.…

Solar power is one of the three main energy sources associated with alternative energy amongst hydro and wind. In today’s world, the need for this alternative energy is at an all-time high as fossil fuels and other conventional sources of energy are beginning to damage this planet’s ecosystem at an alarming rate. Solar energy, although not completely pollution-free, is an inexhaustible fuel source. Every hour energy from the sun is sent into Earth’s atmosphere and within this hour, there is…

of thermal comfort, which depends on the aims and expectations of those who defined it (Chappells, and Shove, 2004). Jiao (2010) stated that, the rate at which human body gain and lose energy, and also the state of comfort is satisfactory once all heat flow in and out of the body are in equilibrium. Also, (ASHRAE 2004), described it as “the state of mind that expresses satisfaction with the surrounding environment.” This definition highlights subjective and psychological dimension of thermal…

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…

Throughout our lives we have been living off the energy source of fossil fuels, but what if there were other sources of energy besides the fuels? And what could they be? Well, there are many other methods of gathering energy. There is solar, hydrogen fuel cells, biofuel, geothermal and more. But today you’ll be reading about the pros and cons of fossil fuels, wind energy, and thermal energy, more precisely geothermal energy. As well as some fun facts listed in the below paragraphs. Enjoy.…

another topic mentioned: alternative energy resources. Alternative energy resources are defined as, “current technologies that have comparable or better performance, but do not emit carbon dioxide (Alternative Energy 2015).” Due to the harmful nature of the overuse of fossil fuels, scientists hope to replace them with four alternative energy resources. The four alternative energy resources are solar power, nuclear power, wind power, and hydroelectric power. Solar energy is derived from the sun.…

The ideal relative humidity is between 30 and 50 percent, for optimal comfort. The consistent airflow provides improved air filtration and improved air quality. • Energy Efficiency: Variable-speed motors consume less energy than conventional motors. For example, the variable speed motor uses approximately one-eighth the amount of electricity used for a conventional single-speed fan motor when it operates at half speed. Consequently, the variable…

Introduction Our group came up with a new and never before done idea: a heat insulation cream. This product will be called Heat Wave. Our target markets will consist of Millennials, Generation X, and Baby Boomers. Our promotional plans will focus on social media and door to door selling. The total price of our product will be ten dollars, yielding an approximate profit of four dollars. We aim to sell our product in drugstores and on our own website. Product Our Product, Heat Wave, is a heat…

What do your results tell you? Are there any relationships, patterns or trends in your results? From our [processed] results, we can conclude that the polystyrene cup served as the least effective conductor of heat, the tin mug coming in at a close second. The most effective material for heat conduction was the plastic mug. At the beginning of the tests, all of the water in the cup declined in temperature at a steady, even rate, but once one minute had passed, they had all started to cool down…

Factors That Affect The Best Type Of Attic Insulation For Your Home You have a few choices to consider when it's time to put new insulation in your attic. Some types of insulation work better than others, but they cost more too. You'll examine several factors when deciding on the best type of insulation for your home. Here are some things to think about. Cost If your budget is the deciding factor, then fiberglass batt insulation could be the best choice. Although it is more affordable, you'll…
