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

good approximate results. The audit may also assess the efficiency‚ physical condition‚ and programming of mechanical systems such as the heating‚ ventilation‚ air conditioning equipment‚ and thermostat. A home energy audit may include a written report estimating energy use given local climate criteria‚ thermostat settings‚ roof overhang‚ and solar orientation. This could show energy use for a given time period‚ say a year‚ and the impact of any suggested improvements per year. The accuracy of energy

Two years ago I purchased an Energy Star home in a newly developed community in Maryland. These types of homes can help homeowners reduce their energy usage by including proper sealing techniques‚ air barriers‚ increased isolation‚ programmable thermostats‚ low E windows and CFL bulbs. There are several different forms of energy I use throughout the year at home‚ work‚ and while traveling and the amounts of these energies I use varies with the different seasons. At home the main sources of energy

------------------------------------------------- ABSTRACT Separation processes by using the application of membrane have become highly demand in various industries. In this newly separation process ‚ the membrane function as a semi-permeable barrier and the separation process occur by the membrane controlling the rate of movement of various molecules between two liquid phases ‚ two gas phases or a mixture of a gas phase and liquid phase. In industries‚ many companies have high demand on both quality

Household energy consumption is examined in the specific context of home heating expenditures. Analysis of home heat costs across stages of the family life cycle reveals a distinctly different pattern than previously found when total household energy costs were examined. In contrast to the curvilinear pattern where expenditures peak during middle stages of the life cycle‚ these data show a positive linear relationship where higher costs are associated with elderly consumers. The research focus is
