Why do supermarket refrigerators not have doors?

Asked by occ (4070points) July 22nd, 2008

Whenever I go to the supermarket and see the open dairy cases, the system seems terribly energy-inefficient . Why don’t supermarket refrigerators have doors? How much energy is wasted by this process? And in a time of high energy prices wouldn’t it make economic sense for supermarkets to add doors?

Hmm.. the super markets here have glass doors. The milk and juices are behind doors. The ice creams and frozen foods, too.

i have seen this at a local supermarket too. why, it’s a mystery. it’s not one of my favorite places to get a 6-pack thats for sure.

The obvious answer is for convenience, but perhaps saving energy will trump convenience in the near future.

One reason is that the technology was such that when condensation formed on the doors, the customers could not see the merchandise. What you can’t see, you don’t buy so the energy loss was worth it to them.

New fixes for the problem are available now so they probably change as they need to replace equipment (which is very expensive).

so people can’t walk into them?

I believe it’s a convenience thing.

“Why should people have to open doors for things they need frequently!? pft!”

..money..money..money.

Update: One of the smaller grocery stores here just added those plastic flappy things. Still easy to get into and doesn’t let out as much cool air.
