| Abstract | The pickup’s truck air-conditioner is one of the major of environmental impact of pickup’s
truck. In this research, IMPACT 2002+ is used to investigate the environmental impact of
pickup’s truck air-conditioner ranging from manufacturing phase, use phase and end-oflife,
respectively. On the manufacturing phase, we investigate the environmental
performance of the material composition, the production processing and the transportation.
On the use phase, we investigate the environmental performance of fuel consumption of
air-conditioning’s system and we analyze the weight of air-conditioning system on fuel
consumption. For the end-of-life, since the waste treatment of vehicle’s part in Thailand is
unsystematic, we assume that the entire air-conditioner’s components are recycled.
Since the entire life of air-conditioner’s components is investigated, the result interprets
that the compressor is has the highest environmental impact whether the manufacturing
phase or the use phase whiles it gives the most environmental benefit during the recycle.
Finally, for the conclusion and recommendation, it is concluded that the compressor has
the highest environmental impact whether the manufacturing phase or the use phase whiles
it gives the most environmental benefit during the recycle . On the manufacturing phase,
we recommend that the compressor’s manufacturers should replace the aluminum wire
with the copper wire. Hence, we recommend that the manufacturers in Thailand to stop
purchasing R134a and they should purchase R744, if this method is implemented, the
manufacturing phase will be improved for 34%. For the use phase, the fuel consumption is
the major of environmental impact and the refrigerant is also another factor of
environmental impact. As we analyzed, the compressor has the highest environmental
impact whether the fuel consumption of itself or the weighting of itself. Hence, we
recommend the pickup’s truck user to stop using diesel and they should be using biodiesel.
In addition, we recommend the compressor’s manufacturers to downsize the
compressor to reduce the fuel consumption. For the refrigerant, since R134a has the
highest greenhouse gases, hence, the maintenance’s shops in Thailand should stop
purchasing R134a and R744 should be replaced. At the end-of-life, the result interprets that
it gives environmental benefit during the recycle and they should be remaining of recycled.
But as we mentioned before, the waste treatment of vehicle’s part in Thailand is
unsystematic and we recommend that the 2nd hand’s shops should be systemized and
optimizing the facility. If these methods are implemented, it will give environmental
benefit. |
