amount of reflected light. The light from the Sun that is not reflected is absorbed insidethe active region of the device. The active region in a solar panel consists of several very thin layers,some only a few atoms thick, of various types of semiconducting materials. The absorbed light generatesequal amounts of positive and negative electric charge inside the semiconductor and a built-in electricfield drives the charge through the circuit as direct electric current. The direct current (DC) is supplied toan inverter that converts it into alternating current (AC). The alternating current is supplied to the existingelectrical power grid of the building thus reducing the need for external power generation.ADVANTAGES OF SOLAR POWER:RENEWABLE

Concluding ThoughtsThe future of HVAC design is exciting and more important to the future of the U.S., and theworld, than at any point in the past. However, this places great educational demands on thecurrent systems in place to produce qualified HVAC entry level engineers. The needs ofindustry are growing and are not likely to stop any time soon. Students must be prepared tostudy more topics and material during school and after hire. Educators must be prepared toupdate existing curriculums to reflect changes in the industry. They must also be willing toembrace new teaching

This can be observed in the correlation between meanmonthly temperature and electicity and gas demand (Figures 3 & 4). Electricity varies in directrelation with temperature, which reflects that the majority of electric demand is due to airconditioning during warm periods. In contrast, natural gas varies inversely with temperature asits primary use is for heating during cool periods. Both electricity and gas are required for otherpurposes and these values can be seen as the“off-season” demand. These baseline values Page 22.566.6indicate the

The world equipment demand for heating, ventilation and air-conditioning(HVAC) has increased from 50 billion US dollars in 2004 to more than 90 billion US dollars in2014 and for the US from almost 11 billion to 19 billion US dollars over the same period [3]. Areduction in the HVAC energy consumption load would reflect a significant reduction in the totalenergy consumed.In this paper, the improvement in refrigeration efficiency and COP were analytically investigatedby looking into a shaded condenser as compared to unshaded units.

This instrument allows for themeasurement of Beam and Diffuse irradiance as well as reflected irradiance. A Pyranometer isan instrument that has a 180° field of view so it absorbs all the solar irradiance from itssurroundings and delivers a digital reading that can be logged with a micrologger (not shown).The micrologger used is capable of measuring a change in voltage as low as one microvolt.

estimations for practical designs. b) Cool Roofing New technologies are now becoming available to finish roofs that can divert incoming solar radiation that heat up the top floors of buildings. Conventional asphalt and tar shingle roofs are being replaced with ‘green roofs’: rooftop gardens that absorb sunlight and moderate rooftop rainwater runoff. However, green rooftops may not be appropriate atop all buildings, particularly those with steep roof slants, or where regular maintenance is problematic. Group B proposed the use of a ‘cool roof’ coating, which is a pigment or coating that reflects sunlight and insulates the top floor of a building from heat that would otherwise be transmitted to the upper

Module 4 deals with nanotechnology that offers several benefits when makinginexpensive and efficient solar cells on a large scale. In this context, nanostructured layersin thin film solar cells offer three important advantages. First, due to multiple reflections,the effective optical path for absorption is much larger than the actual film thickness. Second,light generated electrons and holes need to travel over a much shorter path and thusrecombination losses are greatly reduced. Third, the energy band gap of various layers canbe tailored to the desired design value by

Average speed for the day was 8.1mph. It is noted from Figure 4 that the average monthly wind speed is 8 mph for Mercedes.This data reflects a typical January day. Expectedly, wind mostly blows during afternoons andslows down significantly during early mornings. While early morning wind speed drops to below5 mph for several hours, the speed picks up as high as 20 mph and above, occasionally hitting 25mph.
