3. INTRODUCTION

4. 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.

5. BACKGROUND
To safe the environment from the global warming
2. To ensure a better atmosphere for our next generation

6. WHY THIS STUDY?
● There is no policy or monitoring and regulating institution in GO & NGO level
● DoE (2005) found 2.5 million CFC refrigerators in Bangladesh
● But still a huge number of CFC Refrigerators are available in Bangladesh
● Therefore it is necessary for studying present status of domestic refrigerator

7. OBJECTIVES
1. To identify problems of domestic refrigerator for food preservation that encountered by consumer, manufacturer and repairer
2. To study on different refrigerators and compare based on eco friendly status

8. Materials &
Methods

9. METHODS
1. Questionnaires
2. Interview schedules
3. Literature review
4. Communicated with appliance dealer, consumer and repairer shop

10. METHODS (Contd) A qualitative research design will be employed through
Incorporating interviews
Participant interaction
Field observations
Document review
This approach will be applied to examine
Current status of refrigerators
The Brand commonly used most in Bangladesh
The noise level of the refrigerators
Energy consumption

11. SELECTED SITES Districts: Levels: Dhaka Mymensingh Bogra Rangpur

14. CUSTOMER DEMAND OF REFRIGERATOR AVAILABLE IN BANGLADESH

15. CUSTOMERS’ COMPLAIN Slow ice formation Noise
Time required for ice formatting
Noise Level of Different refrigerants
Slow ice formation
Noise
Less Warrantee period in well-known brand

16. REPAIRERS’ COMPLAIN
HC blend refrigerant is not suitable for conventional compressor
They didn’t get HC blend refilling implements or equipments due to unavailable circumstances from “National ODS phase-out plan” training program

17. MANUFACTURERS’ ACTIVITIES
Manufactures are supplying refrigerator according to the demand of the consumers
The well-known refrigerator companies are generally using eco-friendly refrigerants because of international monitoring and protocols.
Sometimes the well-known companies impose there old or banned model refrigerator

18. COST OF DIFFERENT REFRIGERANTS

19. CONCLUSION &
RECOMMENDATION

20. CONCLUSION
● LG Butterfly, Walton, Samsung, Singer, Sony Rangs are the aged and reliable refrigerator brands in Bangladesh
● R12, R22, R134a, R600 and R600a are the most available refrigerant for domestic refrigerator. R600 and R600a are the eco-friendly refrigerant according to international protocols
● The complain level of R134a is less than R600 and R600a. R600a makes noise after refilling in conventional compressor
● The refrigerators having aluminum compressor make more noise compared with copper compressor

21. RECOMMENDATION
The literature shows that, R-123, R-152a and R-32 strike a good balance between ODP, GWP and efficiency. However, the use of R-152a and R-32 is limited because of flammability. Therefore, it is essential to conduct further details study on the issue
Govt. should make policy to ensure the use of eco-friendly domestic refrigerators and to ban the low quality domestic refrigerators.
It is necessary to conduct further research about other eco-friendly refrigerants
