ENERGY SAVING FACT SHEET Introduction Central building cooling options include water chillers and direct-expansion (DX) A/C units. Chillers use a refrigeration cycle to cool water to 42º F to 55º F for pumping to chilled water cooling coils. Air is then blown over the chilled water cooling coils to provide cool air to the conditioned space. DX systems also use a refrigeration cycle‚ but distribute refrigerant directly to DX cooling coils – some are packaged in a single housing‚ others are split

Daylight savings time‚ it happens two times a year‚ causing a multitude of occurrence‚ some of these being good‚ while some are not so good. However‚ it has been a hot topic for debate recently. To keep daylight savings time‚ or to kick it to the curb is the question many congressmen are asking themselves. Keeping daylight savings time allows the people of the United States to continue with years of tradition implemented during war time that has been a part of their daily lives ever since which is

Geothermal Energy Introduction The Geothermal is a clean and sustainable (renewable) energy. It has been estimated that the heat of the centre of the earth may reach 6000°C. It has been found that the increases one degree °C for 30-50 meters. The word geothermal is derived from Greek language where the first syllable “Geo” means “earth” and the second syllable “thermal” means “heat”. How it works The geothermal energy should be made useful through electrical generators. We are not free to dig

Energy Transformation Conduction‚ convection‚ and radiation are things that exist in our life. Thanks to that stuff we have things like electricity and things to cook too. I am going to explain things about energy transformation. Heat transfer is the way heat moves through matter to change the temperature of other objects. There are three types of heat transfers‚ Conduction‚ Convection‚ and Radiation. The first kind of heat transfer‚ conduction‚ is heat transferring through direct contact of materials
