Improvement of air quality for a passive earth air heat exchanger (EAHE)

Global warming and the excessive emission of CO 2 due to human activities contributed to the increase of temperature in the earth's atmosphere. The increase of the earth's temperature thus leads to the reduction in the thermal comfort. In order to improve the level of thermal comfort, many...

Sanitary engineering Global warming and the excessive emission of CO 2 due to human activities contributed to the increase of temperature in the earth's atmosphere. The increase of the earth's temperature thus leads to the reduction in the thermal comfort. In order to improve the level of thermal comfort, many air conditioning systems are designed. Earth Air Heat Exchanger, (EAHE) is a device used to provide the cool or hot air into the building's interior by taking advantage through the soil thermal conductivity. However, the air quality drawn out from the EAHE system was not assured. The typical EAI-IE system usually prioritizes the cooling/heating effect of air rather than its quality.

The objective of this thesis was to determine the quality of air drawn out from the EAHE system and how the use of filters helps in improving the performance of the air quality. A small scale model of EAHE was constructed which made up of a horizontal 2.5 in Polyvinyl Chloride (PVC) pipe buried 0.5 in underground and attached to an air blower/pump. The air blower was used to drive surrounding air into the buried pipe. A filter attachment consists of a green cotton filter was then attached to the outlet of the system. Additionally, filtration system was later further improved by adding activated carbon powder with the readily available filter to determine the improvement in the air quality of the EAHE system. The results indicated that a simple EAFIE system can be constructed to reduce ambient temperature about 0.3°C. The temperature was further reduced to a maximum of 2.9°C with the addition of filter attachment. Furthermore, in the case of air quality dropped, the filter attachment improved the air quality supplied through the EAHE system up to 93% for all parameters considered. The use of EAHE system with activated carbon filtration system may significantly reduce temperature of the building's interior, economical, as well as improving the air quality drawn into the dwelling. 2013-06 Undergraduates Project Papers NonPeerReviewed application/pdf en http://umpir.ump.edu.my/id/eprint/10821/1/NURFARAHIN%20BINTI%20SHARKAWI.PDF Nurfarahin, Sharkawi (2013) Improvement of air quality for a passive earth air heat exchanger (EAHE).
