Reusable Energy And Cooling Systems Essay

2027 words - 8 pages

Traditional cooling method can initiatively decrease the inside temperature, but it may consume extra energy, while novel building structure can ease the problem of energy consumption through utilizing nature energy and reducing the conduction of heat which from exterior to inside.

At present, to meet the increasing need of society and environment, bringing in reuse energy and advanced structure are essential in cooling system of intelligent buildings.

Cooling means “the amount of heat that must be removed from a building in order to maintain desirable indoor temperature and humidity conditions” (M.Santamouris, 1993). The most comfortable temperature and humidity for human is 18-25°C and 45% RH - 75% RH, the aim of cooling is changing the indoor condition to be suitable for people. There are many methods to achieve, it divides into two parts, one is using energy, another is structure of building. Both of these have negative and positive effects on intelligent building.

In addition, the most widely using in cooling control is traditional ventilation, for the reason that they are easily found and suitable for normal cooling system, the other one is the structure of building, different structures and figures may have different impacts for indoor cooling, this kind of method may be save more fuel and decrease pollution.

However, the traditional energy has negative impacts on global environment, due to energy consumption and greenhouse emission during cooling processing, it has increased global warming, soil pollution and fuel-wasting. Thus it is necessary to search new ways to solve these problems.

There are two traditional methods, one is adopting low energy technologies such as natural ventilation and mechanical ventilation, it may cope with environment pollution greatly, and bring in new life style for human, the other is the improvement of the structure of intelligent building has changed the old fashioned form of common buildings. Thus new intelligent building can be more convenient and comfortable for human to live.

Although there still has disadvantages between the improvement of traditional system and new structure, new energy need more advanced technology which means high cost; new structure may contain new materials and technics, Thus before designing a new intelligent building, it should be consider more aspects, such as cost and available technology.

Traditional cooling system: The most ordinary traditional cooling methods contain natural ventilation and mechanical ventilation. Natural ventilation uses air velocities by natural forces (wind and buoyancy) in openings such as doors and windows to reduce indoor temperature and humidity to provide comfortable environment and fresh air to occupants (Jankovic, 1993).

Mechanical ventilation: Mechanical ventilation usually uses fans which is the most common equipment in cooling system to...
