“Top-freezer functionality is relatively uniform across manufacturers,” says Kennet Johansson, an appliance merchant at The Home Depot. “These units feature a single compressor that cools the freezer, with cold air routed down to the refrigeration compartment through a series of vents or baffles.”
Why freezer is in upper part of refrigerator?
Freezer is the source for the refrigerator’s coldness. When the freezer is placed on top, the cold air produced from it is denser than the warmer air in the bottom. So cold air being dense sinks down and the warm air is forced to rise up so when the warm air rises up it and gets cold in the freezer.
Which is better freezer on top or bottom?
Energy Efficiency Winner: Top FreezerIn general, top freezers are more energy efficient than bottom freezers. … Therefore, a bottom freezer is closer to the compressor and forces it to work harder to keep cool whereas a top freezer is further away making it easier to keep heat out with less effort.
What is the coldest part of a top freezer refrigerator?
Cold air sinks, so it collects at the bottom and, in a fridge freezer, the bottom shelves will be coldest. But in a fridge with an ice-making compartment at the top, it will be the top.

Why is a top freezer more efficient?
Energy Efficiency Top freezers are generally more energy efficient than bottom freezers. Since the compressor that generates heat while working to keep the fridge and freezer cool is located under the unit, it takes more energy to keep a bottom freezer at optimal storage temperatures.
Are top freezers better than side-by-side?
Freezer on Top Top freezers have more room than bottom freezers in comparably-sized refrigerators. They are also the most energy efficient. The Department of Energy says top freezers use up to 25 percent less energy than side-by-side or bottom freezers, so they save money.
Why are bottom freezer refrigerators more expensive than top freezer?

Which type of refrigerator freezer is most energy efficient?
side-by-side fridges — yes, it does matter where that freezer sits: The most energy efficient refrigerator style is a top-mount freezer refrigerator.

Why is the freezing chest?
Textbook solution The freezing chest of a refrigerator cools the remaining space of the refrigerator by convection currents.
How does the evaporator work?
The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment. When the liquid refrigerant reaches the evaporator its pressure has been reduced, dissipating its heat content and making it much cooler than the fan air flowing around it.
How does a refrigerator evaporator work?
The evaporator is located inside a refrigerator and is the part that makes the items in the refrigerator cold. As the refrigerant turns from a liquid into a gas through evaporation, it cools the area around it, producing the proper environment for storing food.
Should you keep bread in the fridge?
