Freezers at bottom

Few might have got a question, why we have freezers in Refrigerators are not at bottom?

We use freezers little less than other part of Refrigerators and still we have freezers placed conveniently at top while vegetable basket, which most of household use at least twice are placed at bottom and which requires more bending to access it i.e. human energy.

Many Product managers might have already thought about it? Product Engineering would be able to design such product easily. I read somewhere one of Japanese company in 1976 did market research and found that freezers are used only 20% of time, yes I'm saying Market research was completed almost 33 years ago.

On doing some research I found that Freezers at bottom are more energy efficient as warmer air rises up so it is easier to design warmer part of Refrigerators being at top while cooler part i.e. Freezer at bottom.

Interesting is it??

In this era of climate change, Refrigerator manufacturers should think about it?
