Comparison Whirlpool ART 9811 vs Whirlpool ART 6711

The total volume of a refrigerator is the sum of the volumes of all its compartments, which can vary in specific capacity between different models. It's important to consider this when choosing a refrigerator.

A larger volume for a refrigerator can be beneficial for accommodating more food, but it can also increase the price and size of the appliance. This is especially important to consider if you plan to build the refrigerator into a specific space.

The circuit in a refrigerator refers to the cooling system connected to the compressor. Typically, the number of circuits corresponds to the number of compressors, but some models have two cooling circuits are connected to a single compressor for the refrigerator and freezer. While a dual-circuit refrigerator with one compressor cannot turn off one compartment while keeping the other functional, it allows for separate temperature control.

The presence of the No Frost system in one or more refrigerator compartments.

This system prevents the formation of frost on the walls of the compartment, as happens in models without No Frost. No Frost is a technology used in refrigerators that removes moisture from the air inside to prevent frost buildup. It works by condensing water vapor and evaporating it outside the refrigerator. However, this feature can cause food to dry out more quickly, so proper packaging is essential.

In modern refrigerators, No Frost can be provided both in the refrigerator and in the freezer, and often in both compartments at once. When deciding whether to choose a No Frost refrigerator, it is important to weigh the benefits of not having to defrost against the possible downside of faster drying of food products. This feature is more advantageous for the freezer, as the benefits of No Frost are more significant at sub-zero temperatures and the disadvantages are less noticeable.

Common features that apply directly to the entire appliance include holiday mode, control via smartphone, child lock, display, door alarm, auto door closer, and reversible door. More about them:

— Holiday mode is an energy-saving feature intended for times when the refrigerator is not in use for an extended period, such as when there is no food inside. During this mode, the temperature inside the fridge compartment is kept around 12 degrees, which helps prevent the development of mold and unpleasant odors.

— Control via smartphone. This feature allows users to access and manage the unit from anywhere with an internet connection. This is achieved through Wi-Fi connectivity to a router or smart home system. The control can be done through a smartphone application or a web page available on any browser. This function provides users with information about the refrigerator's operating mode, including temperature, humidity, malfunctions, and emergency situations. The control via the internet is convenient and provides flexibility in controlling the refrigerator.

— Child lock. Many modern refrigerators come with safety features designed to prevent small children from tampering with the settings. These features usually involv...e locking the control panel to prevent accidental adjustments. However, child locks for the doors are not typically included as a standard feature and must be purchased separately.

— Display. Displays can be found on refrigerators of various levels, from basic to advanced models. Regardless of the level, the display adds convenience to the operation of the unit by providing detailed information about its operation and displaying useful data, such as the time. In some cases, the display can also integrate with other smart home components. However, the cost of refrigerators with such features is typically higher.

— Door alarm. The refrigerator door alarm system alerts the user if the door has been left open for an extended period of time or not closed properly. This prevents spoilage of food due to a critical increase in temperature. The alarm usually gives a sound signal after a certain amount of time and some models also have a light indicator to confirm the correct closure of the door.

— Auto door closer. Auto-closing devices are installed on some refrigerators and are responsible for assisting in the closing and, in some cases, opening of the door. This helps to reduce the risk of leaving the door partially open or closed, while also ensuring a smooth, shock-free movement that can prolong the life of the refrigerator.

— Reversible door. Refrigerators with a classic design offer the ability to choose the location of the hinges, allowing users to decide on which side the door will open for optimal access. note that this function is only available for classic design models, including refrigerated display cases (see “Type”). This feature is not available in Side-by-Side and French Door models due to their design.

The refrigerating compartment is designed for storage of products that do not require freezing, i.e. cooling down to temperatures below zero. The temperature range inside varies from +2 to +10. In almost all modern refrigerators, it is this compartment that has the largest volume.

To ensure optimal performance and food quality, it's important to choose the appropriate volume for the refrigerating compartment based on your actual food storage needs and how often you replenish your supplies. Overfilling the compartment can have a negative impact on both the refrigerator's performance and the quality of the stored food.

For singles or couples, a refrigerating compartment of up to 200 liters is enough, while families or those who stock up on food should opt for models with up to 400 liters. Vertical refrigerators with separate freezer access are suitable for those who need moderate storage space, while side-by-side refrigerators with their typically larger volumes are a good option for those who require even more space and have ample free space.

Apart from shelves, there are several additional compartments in a refrigerator, including a a freshness zone, a humidity zone, a multi-zone and a shelf for bottles.

— Freshness zone.It is a special compartment in a refrigerator designed for storing fresh products for an extended period. The temperature in this zone is slightly lower than the refrigerating chamber, typically around zero degrees, earning it the nickname "zero chamber". Such conditions help to preserve the freshness of products for up to 3-4 days. However, it's important to note that the temperature in the zero chamber may vary depending on the refrigerator model, ranging from 0 °C to +1...3 °C, which can impact the preservation of stored products.

— Humidity zone. Another specialized compartment, similar to the freshness zone, is designed to preserve the freshness of food items for an extended period. However, this compartment maintains high humidity at the same temperature as the rest of the refrigerator, which prevents the products from drying out. This feature is especially important for refrigerators with No Frost systems, which tend to blow moisture out of the refrigerator, leading to quicker drying of the contents.

— Multi-zone. This compartment in a refrigerator combines several functions of different compartments, such as the ability to w...ork as a refrigerator or a freezer, along with other specific features like quickly cooling drinks, slow defrosting, and cooling hot dishes. Modern refrigerators offer more extensive capabilities with specific features, making the multi-zone compartment a valuable addition. Some models have the entire freezer performing the function of a multi-zone chamber, but most models have a separate compartment for it. The presence of a multi-zone compartment significantly expands the capabilities of a refrigerator.

— Shelf for bottles. It is a hanging accessory, typically in the form of a lattice, that is installed under a shelf in the refrigerator. It allows bottles to be stored horizontally, which saves space in the refrigerator while keeping them organized.

The presence of a LED lighting system in the design of the refrigerator.

LEDs are currently the most advanced type of household lighting due to their high efficiency, providing bright light with low power consumption. They emit minimal heat, making them ideal for refrigerator lighting. Their compact size also allows for even distribution throughout the interior, illuminating all shelves, which is not the case with incandescent lamps that can only shine in one location, leaving some areas poorly lit.

The primary function of the freezer is to store food in a state of deep freeze, which helps preserve perishable products such as meat, vegetables, fruits, etc. for extended periods of time. The necessary volume of the freezer depends on the planned amount of food to be stored and the length of time it will be stored. A larger freezer is particularly useful if you plan to store food for several months. A compact freezer is relevant for short-term storage (for a day or two) or for seasonal devices (for example, in the village). It is best to ensure that the freezer is not overloaded and has enough space for proper circulation of air to maintain the desired temperature.

Refrigerator control panel. To date, there are such options:

— Rotary switches. While a rotary switch technically has the potential to be used for a wide range of functions, in practice, this variety is typically only found in basic models with limited functionality. In such cases, control is often done manually by turning a thermostat knob, with limited options for adjusting temperature, humidity, and other settings.

— Push-buttons. CRefrigerators can have a control panel with classic buttons that offer various functionalities depending on the model. These functionalities can range from basic adjustments (similar to rotary switches) to fine-tuning of temperature and humidity, control of special modes, and more. Compared to rotary switches, push-buttons generally offer a wider range of possibilities.

— Touch. Touch panels are a modern and stylish control option for refrigerators, which requires a light touch to operate. They are considered the most advanced type of control, providing convenient and extensive functionality. Touch panels are typically installed in premium models, where they add to the device's aesthetic appeal with a minimum of unnecessary protruding parts.
