Commercial Air-conditioning or HVAC (Heating‚ Ventilation and Air Conditioning) J.Ilangumaran Commercial air-conditioning or HVAC (Heating‚ Ventilation and Air Conditioning) It refers to the mechanical systems which heat‚ cool‚ filter or dehumidify air in a room or building. HVAC systems control the ambient environment (temperature‚ humidity‚ air flow‚ and air filtering) in homes and commercial buildings and are crucial in maintaining environmental conditions in critical applications

WINDOW TYPE Submitted By JOEL A. OOMMEN Air Conditioner Window Type: [pic] . An air conditioner is an appliance‚ system‚ or mechanism designed to extract heat from an area via a refrigeration cycle. In construction‚ a complete system of heating‚ ventilation‚ and air conditioning is referred to as "HVAC." Its purpose‚ in a building or an automobile‚ is to provide comfort during either hot or cold weather. History: In 1820‚ British scientist and inventor Michael Faraday discovered that

energy sources‚ climate change. So it is an big challenge for present and future generations as the cost of energy increase and its supply decrease‚ older buildings needs to modified and new buildings designed to use less energy. The optimization of heating‚ ventilation and air conditioning system in term of energy efficiency is part of this assignment as how wisely to manage and use the energy recourses in our daily life and how the technology can help us in minimize the energy use in building sector

Energy Efficient Building Windows Energy efficient windows have multiple layers of glass. The reason for this is because the more layers of glass you have the better it insulates the house. Three or four layers of glass are one of the best because you have more airspace in between layers. A smaller airspace doesn’t insulate the building as well as a thicker airspace would. The thickest an airspace should be is 1 inch because any thicker than that will cause the glass of the window

within the building and may control temperature‚ carbon dioxide levels and humidity within a building. As a core function in most BMS systems‚ it controls heating and cooling‚ manages the systems that distribute this air throughout the building (for example by operating fans or opening/closing dampers)‚ and then locally controls the mixture of heating and cooling to achieve the desired room temperature. A secondary function sometimes is to monitor the level of human-generated CO2‚ mixing in outside air

CHP Laboratory Analysis Introduction Combined Heat and Power system is a technology that produces electricity and thermal energy in the same process. In this way‚ optimum use can be made of the energy available from the fuel. During the electrical power generation‚ heat is lost‚ which is used to increase the internal energy of the fluid‚ water in this case‚ through the exchangers. Hot water is either directly pumped to the end user during the winter season of the year or it is used to

air-conditioning system utilizing solar energy would generally be more efficient‚ cost wise‚ if it was used to provide both heating and cooling requirements in the building it serves. Various solar powered heating systems have been tested extensively‚ but solar powered air conditioning systems have received very little attention. Solar powered absorption cooling systems can serve both heating and cooling requirements in the building it serves. Many researchers have studied the solar absorption air conditioning
