Effective HVAC System For Schools

Healthy and comfortable indoor air climates are essential for any type of building environment. Particularly, classroom air environment and thermal comfort has an important role in the teaching and learning process as it could be engaging students in activities that promote their performances, such as understanding of concepts, abilities of problem solving, and attitudes towards learning, and etc. In order to achieve such better indoor air environment and thermal comfort in classrooms, school buildings usually have been operating with air conditioning system by design norms. By carrying out cooling and heating load calculations one can estimate the capacity that will be required for various air conditioning equipment. The types of air conditioning system selection depends on many factors, including the costs to implement, occupancy, provided security and protect from other hazards. Active cooling using refrigerant-based devices can be replaced by passive cooling methods using surrounding natural resources. This study explains known hybrid technologies, mechanically powered, using natural resources.
