REFRIGERANT
TECHNOLOGY
MAJOR PROBLEMS CAUSED BY
DOMESTIC REFRIGERATOR
Cooling refrigerants such as chlorofluorocarbons (CFCs) and hydrofluorocarbons (HFCs) will cause negative impacts to the environment. 
Description:
PROBLEM 1
Leakage of chloro-fluorinated refrigerants will cause cause ozone depletion and lead to high global warming potential. 
Hydroflurocarbons will lead to high potential releasing greenhouse gases and accelerates global warming
The domestic vapour compression household refrigerators are heavy and nonportable may cause difficulty in refrigerated transportation and lead to broken cold chain. 
Description:
PROBLEM 2
Almost 1 in 10 worldwide – fall ill after eating contaminated food and 420,000 die every year and estimated that nearly 50% of freeze-dried and 25% of liquid vaccines are wasted each year primarily due to broken cold chains. 
SUSTAINABLE REFRIGERANT TECHNOLOGY
OUR SOLUTION
HERE'S
A portable refrigerator is designed based on thermoelectric technology with input powered using power bank. The working principle of thermoelectric cooling uses Peltier effect to create a temperature difference by transferring heat between two electrical junctions.
