To provide the best circulation in the entire system. Freezers are designed for maximum circulation, while refrigerators are normally fitted to be at the top or in the middle of the cabinet, where airflow tends to be more limited.
Freezers are a crucial part of the refrigerator and freezer, which are highly valued as a crucial storage resource in our modern lifestyle.
All over the world, refrigerators and freezers are almost always placed on top of refrigerators, and there are three types of freezers: standard freestanding freezers (which have only one door), and freestanding cabinets (which have two doors), and the most common cabinet freezers (which have four doors). While cabinet freezers can still work in a standard refrigerator setup, they tend to be designed for cooler, fresher environments and lack the cooling power of other freestanding freezers.
Besides having a fully insulated and chilled environment, refrigerators usually have an active cooling system to maintain a controlled temperature of a refrigerator. Unfortunately, while refrigerators have many benefits, like the relatively low consumption of energy and the fact that they do not require filling with ice, the refrigeration units do not have the cooling power to cool down the ambient air temperatures as efficiently as possible. So, while refrigerators provide cold storage, they do not offer sufficient cooling capabilities to cool down our climates.
A key ingredient in cooling down a refrigerator is a compressor, a motor that can generate a small amount of electrical power. The modern refrigerator and freezer units use smaller high efficient compressors in their refrigeration systems.
Compressors are known for providing efficient cooling power, but their high power consumption poses a considerable burden on consumers and energy providers. While energy consumption varies from fridge to fridge and even from appliance to appliance, refrigerators are usually significantly more power-hungry and consuming almost four times more energy than an average refrigerator.
And the process of cooling up the refrigerators is not that easy either. Cooling up an average refrigerator in modern times is typically a complex process involving many stages. In the beginning, the refrigerators are set to cold temperature, while the compressor starts to provide a relatively high flow of air.
Air from the compressor circulates through the refrigeration unit to cool down the refrigerating unit. This is followed by another process, which involves increasing the amount of cooling power in the compressor unit and further chilling and cooling the refrigeration unit. Once this process is complete, the refrigeration unit is then allowed to come back to a normal temperature, and the compressor unit is turned off.
If the refrigeration unit does not come back to a stable temperature, the compressor will start to run at high power and waste electricity. Also, the refrigeration unit will eventually come back to a safe temperature, but the compressor will be engaged again when air is pumped into the refrigeration unit. This is another process, and the refrigeration unit will come back to a stable temperature when the compressor is turned off, just to start all over again.
And, since refrigerators can have an active cooling system, the process can be repeated repeatedly until the ambient temperature in the refrigeration unit is achieved. In addition to this process, air circulation is required to bring more fresh air in to decrease the humidity in the refrigeration unit.
Now that you know more about why freezers are placed at the top of refrigerators and the characteristics of refrigerators, and how they influence our surroundings, it is time to take action. Before you buy an energy-hungry and high electricity consumption refrigerator or freezer, consider what the end product might be and what the benefits are. Consider how your house or the environment will be affected by the high energy consumption.
