Which type refrigerator is better for home use?...

I think it depends on how large is your house. If you have a big house, a bigger refrigerator is always the better. I have a big refrigerator at home, but it is not the biggest because my room is not big enough to have a huge one. My refrigerator is always very full. Before you buy a refrigerator, you have to decide the size at first. And then you have to consider how much power it will spend. Today there are many refrigerator which can save the energy. And then you will have to consider the brand, sales-after service, price etc.
