Evaluation of cooling wall system and phenolic resin as thermal barrier in Buildings
In recent years,thermal barrier technologies have become an important energy-saving for space heating and cooling of residential and commercial buildings in many countries.Building energy efficiency can be improved by implementing either active or passive energy efficient strategies.Improvements to heating,ventilation and air conditioning systems etc.can be categorized as active strategies,whereas,improvements to building envelope elements can be classified under passive strategies.Using cooling wall system and phenolic resin as thermal barrier are one of the effective passive strategies.Cooling wall system is composed of galvanized iron pipes located inside of walls.Fluid flows inside the pipes and then supply constant cooling temperature.In the study,system using of groundwater as renewable energy source for pipes cooling.The groundwater at depth of more than 5 meters below the surface has constant temperature year round.Lower temperature groundwater would cool the pipes of system by heat exchange process to achieve the cooling effect of wall.The phenolic resin is proposed as construction materials to use its thermal insulation property for developing a comfortable living and working indoor environment.The phenolic resin is an environmental friendly material,and an excellent thermal barrier.In this research,cooling wall system and phenolic resin were evaluated to reduce the thermal transfer from sunlight into the buildings,thus reducing the electricity consumption needs for air conditioning of the buildings.
