of years. Solar energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy‚ such as heat and electricity. * In the 1830s‚ the British astronomer John Herschel famously used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. solar energy can be used to: * Heat water — for use in homes‚ buildings‚ or swimming

Hardik Patel 4/28/2011 Alternate energy source: Solar Energy Solar energy is one of most popular energy sources around the world. this is because it us conveniently to obtainable‚ as well as space efficient. It doesn’t take up a lot space and give superb energy. The sun is one of the most reliable energy sources on this planet. This is because the sun has been predicted to stay “alive” for many million years to come. It’s radiation also does not fluctuate from day to day like other sources

Executive Summary The following is a thermal‚ mechanical and hydraulic design response report to a heat exchanger problem where ethylene glycol and a poor quality feed of water are put through a shell and tube exchanger with the objective of cooling the ethylene glycol feed. A shell and tube exchanger was chosen over several other exchangers due to its high efficient performance and its relative ease of maintenance in processing these fluids. From the data given and specific heat capacity researched

achieved through passive solar‚ solar thermal energy conversion and photovoltaic conversion (sunlight to electricity) methods. >Passive solar does not use thermal energy to create a cold environment or drive any direct cooling processes. Is implemented by using Cool roofs‚ that are roofs that can deliver high solar reflectance (the ability to reflect the visible‚ infrared and ultraviolet wavelengths of the sun‚ reducing heat transfer to the building) and high thermal emittance (the ability to radiate

The chiller efficiency depends on the energy consumed. Absorption chillers are rated in fuel consumption per ton cooling. Electric motor driven chillers are rated in kilowatts per ton cooling. • KW/ton = 12 / EER • KW/ton = 12 / (COP x 3.412) • COP = EER / 3.412 • COP = 12 / (KW/ton) / 3.412 • EER = 12 / KW/ton • EER = COP x 3.412 If a chillers efficiency is rated at 1 KW/ton‚ • COP = 3.5 • EER = 12 Cooling Load in - kW/ton The term kW/ton is commonly
