| Abstract: | Air-conditioning system is becoming more and more popular nowadays. Also, Windows normally will not be opened due to security and noise issue. Besides, People concern more with the thermal comfort in their working environment where they spent at least 8 hours a day. Air-conditioning system becomes an essential system in all types of building, such as commercial building, residential building and tertiary building etc. Nevertheless it is always not easy to make a balance between good indoor air quality and energy saving because the consumption of air-conditioning system is almost the largest sector in the overall electricity consumption. Reduce intake of fresh air will reduce the energy consumption in the building but it will affect the indoor air quality in sequence. Therefore, an energy recovery ventilator is a good solution. It can reduce the energy consumption and enhance the indoor air quality due to sufficient fresh air supply. Experimental study and theoretical calculation are conducted in this dissertation. It aims to compare the different between the experimental result and theoretical result. Discussion will be carried out in the comparison part. A case study of an office building using the paper type heat exchanger will be conducted. This case study aims to record the annual energy consumption if the energy ventilator is used. The amount of saved energy can be found in this case study. Discussion and improvement work will be covered in this research. Last but not least, it is found that around 20% of the annual energy consumption can be saved if the air-to-air paper type total heat exchanger. |
