Hi all,
I just want to throw some ideas and get feedback from the community on refrigerator door design.
If anybody notices in supermarkets, etc, the frozen food are kept in glass-doored refrigerators. the prupose of the glass door is so the customers can see if the stuff they're looking is behind door number X, so, no opening door and got nothing, thus, increasing the temp in the compartment for nothing, where this would mean need to consume extra electricity to decrease the temp back to where it was for nothing.
now, the problem with this is that glass, even if it's not a good conductor, it still conducts heat. meaning, it heat from outside will still seep into the compartment, even when it's closed. I have 2 ideas:
1. in normal fridge in houses, we have 2 solid (non transparent) doors, top and bottom. I suggest we change this to a transparent material (glass, plastic, etc), but it a layered design. so the door is something like glass - vacuum - glass. the vacuum between glass is to prevent heat transfer from outside to inside compartment.
2. create more compartments in each section. so, right now, there are only 2 sections in a fridge --> freezer and refrigerator. normally, refrigerator section is quite big, so, I think it's better to further divide it to several compartment (tray level), so each tray is one separate compartment, so, when we open the compartment, we don't increase the temp for the other compartments.
the main objective is of course to save electricity, in tandem with inverter tech
any input ?
thanks
