HVAC (heating, ventilation, and air-conditioning) systems vary depending on the complexity of room units size from single rooms to large systems, central control, which serves several areas of a building. In large, modern office buildings with heat gains from lights, people and equipment, interior spaces often require constant cooling. Rooms within the building itself (rooms with exterior walls, ceilings or roofs), it may be necessary to heat and / or cooled the weather conditions change hourly or daily outside. In buildings over one story in height, perimeter zones in the lower levels tend to be the penetration of air infiltration without so much control. (more…)

From the turn of the century to 1911, more than a dozen inventors filed patents that improved on the Climax. However, none changed the fact that the heating unit and the storage unit were one and the same and both laid exposed to the weather and the cold night air. Hence, water heated by the sun the night before never stayed hot enough to do the wash the next morning or to heat the bath. In 1909, William J. Bailey patented a solar water heater that revolutionized the business. (more…)

The moisture content of the feedstock affects the gas composition and the energy balance of the process since gasification is an endothermic process. Water vapor, however, is an essential component of gasification reactions. Therefore, there is a trade-off between the extent of fuel drying and the quality of product gas. Drying of the feedstock to a moisture content of approximately 15% is commonly adopted. Fuel drying is likely to be the most energy intensive activity in the biomass gasification process. Important contributions can be made to the energy balance by using flue gases or steam to dry the biomass. The heat used for drying does not have to be high temperature, and a low temperature level is actually desired because it will prevent the evaporation of undesirable organic components. (more…)

In Europe, modern renewable energy sources technologies were explored thoroughly for the first time after the oil embargo/ price crisis of 1973. Notably, market introduction of renewable energy technology started in about 1985, but the renewable energy sources industry has become vital only during the past decade. Accordingly, relevant statistical renewable energy sources data have been systematically compiled only over the past decade, although reliable and consistent statistical renewable energy sources data, collected since 1989, exist for all 15 countries of the European Union and for Western Europe (defined here as the EU-15 plus Switzerland, Norway, and Iceland).

Active solar hot water systems water are usable with air, liquid, vapor or liquid collector fluid or gas to liquid process. Hot water production with an air-heating collector’s distribution for heating is usually performed in the large space heating panel systems. The losses in the process of heat transfer are high. Air systems work not as well as units of the liquid to heat the water. Air systems are generally only capable of hot water 70 to 95F. (more…)

Steam heating is an absolutely wonderful method to heat your home. Steam heat is always driven by steam produced from water in a pot of natural gas, oil and electricity. Then it draws through pipes and radiators and heat exchangers to heat your house or residential. Boiler is used to generate steam from water. When the water boils, steam rises through pipes to radiators to heat. Then, the hot radiators play its role to warm the house. (more…)
