A Bottom Freezer Refrigerator is a home or office cooling device. It has two compartments. An upper and lower compartment. Its upper compartment is a chiller and lower compartment is a freezer. Hence the name bottom freezer.
You keep stuff that needs deep freezing in the freezer compartment and those that need chilling in the cooler.
Although a bottom freezer refrigerator differs in design from its top freezer counterpart, that doesn’t make any difference in cooling efficiency. It only presents a unique taste of style. For example, if the refrigerator’s height is higher, short people or children easily access items in the lower freezer compartment.
Suppose, in a given day, the family’s rate of removing and replenishing stuff from the lower compartment is high. The family members who have to stand on their toes to access the freezer of a top freezer refrigerator, find bottom freezer design convenient.
A basic bottom freezer refrigerator doesn’t have high-end features like the ice cube and water dispenser. With its simplicity, a basic bottom freezer refrigerator requires minimal space in the kitchen or dining area. However, make sure you maintain the recommended distance of two to five inches between the refrigerator condenser and the wall, for ample air circulation. A refrigerator condenser dissipates heat and needs space for the ambient air to neutralize the heat.
Like other basic top freezer refrigerator models, a bottom freezer refrigerator has one compressor. The compressor is the electric motor that pumps the refrigerant around in the refrigerator system in a process called refrigeration cycle. It’s a process that results in heat dissipation at the condenser. The air around the condenser should absorb this heat, and thus the reason you should leave some space between the refrigerator condenser and the wall.
Inner workings of a top freezer refrigerator
Inside the bottom freezer refrigerator chiller compartment, is a small light bulb for illumination.
A defrost heater runs along the door frame, to melt frost that sometimes freezes on the door and block it.
A thermostat is installed inside the upper cooler compartment, and it is marked with minimum to maximum settings. The thermostat switches the compressor off-and-on as the refrigerator temperature dictates.
A user should know whether this intermittent off-on switching exists because it helps in power economy. If it doesn’t, the compressor would run continuously without a stop. This means unnecessary power consumption.
An analog refrigerator thermostat is an affordable field replaceable unit. If yours develop a problem, and you are a lover of DIY, you can buy a new one and replace.
When shopping for a basic bottom freezer refrigerator, the numerous number of models to choose from can overwhelm you. But the bottom line is, focus on time-tested brands.
Quality refrigerator manufacturers install quality compressors and other gadgets on their refrigerators. One sure way of verifying that the refrigerator brand is worth your money is to look at the compressor.
You can also consult a qualified technician or a user who has a good experience with a bottom freezer refrigerator.
Tip: Instead of running a defrost element along the refrigerator door frame, some manufacturers run the condenser tubing. The condensed refrigerant that flows inside the tube is warm, and it melts frost that would trap the refrigerator door. However, there is a disadvantage of a refrigerator built with condenser tubing run along the door frame if the tube is made of iron. Water condensate penetrates the joints to get in contact with the iron tube and cause oxidation.
Eventually, the iron develops pores through which refrigerant leak. If that happens, it would soon be the beginning of a user’s nightmare. She would need to weigh the cost of repairing the refrigerator and buying a new one.
Although every machine has a lifespan, a user should get value for money. Some refrigerators begin to give users a headache so soon.
