ECO-FRIENDLY REFRIGERATOR

Eco-friendly refrigerator may be defined as the device which

fulfills the purposes of a refrigerator Consume less power more efficiently Not harmful to environment & eco-

system.

1.To safe the environment from the global warming

2. To ensure a better atmosphere for our next generation

● ● There is There is no policyno policy or or monitoringmonitoring and and regulating institution in regulating institution in GO & NGOGO & NGO level level

● ● DoE DoE (2005)(2005) found found 2.5 million CFC2.5 million CFC refrigerators in Bangladeshrefrigerators in Bangladesh

● ● But still a huge number of But still a huge number of CFC CFC RefrigeratorsRefrigerators are available in Bangladesh are available in Bangladesh

● ● Therefore it is necessary for studying Therefore it is necessary for studying present status of present status of domestic refrigeratordomestic refrigerator

CONCLUSIONCONCLUSION

The literature shows that, The literature shows that, R-123R-123, , R-152aR-152a and and R-32R-32 strike a good balance between ODP, strike a good balance between ODP, GWP and efficiency. However, the use of GWP and efficiency. However, the use of R-R-152a152a and and R-32R-32 is limited because of is limited because of flammability. Therefore, it is essential to flammability. Therefore, it is essential to conduct conduct further details studyfurther details study on the issue on the issue

Govt.Govt. should make should make policypolicy to ensure the use to ensure the use of of eco-friendlyeco-friendly domestic refrigerators and to domestic refrigerators and to banban the the low qualitylow quality domestic refrigerators. domestic refrigerators.
