Hello frends now as you all know its very cool outside so I want to share about refrigerator which makes cool from inside. I got samsung double door refrigerator which got seperate ice and cooling section. The concept is great. You can control temprature of both the sections at difrent points. The refrigerator is able to maintain ice till 10 hours after the machine is off. The machine is having cool sensor which control the temprature required by the article. Contineously opening of door does reduce or decrease the efficiency of the machine.
