Comparison Bosch KIN 86KF31 vs Bosch KIN 86AD30

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.

Common features that apply directly to the entire appliance include holiday mode, control via the Internet, 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 the Internet. 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 in...volve 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.

In refrigerators with dynamic air cooling, the air inside the working compartment moves not due to the temperature difference, but due to the operation of the built-in fan. This ensures uniform distribution of cold air and the same temperature throughout the volume.

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.

The quantity of freezer drawers in a refrigerator affects the optimal organization of frozen foods. A larger number of drawers allows for better separation of different types of frozen products. However, in the majority of standard two-compartment refrigerators, there are typically three freezer drawers.

One of the desirable features in a freezer are big drawers that can accommodate large items such as a whole turkey. However, what one manufacturer considers as a large drawer may differ from another manufacturer's definition. In some cases, a large drawer in one model may be equivalent in size to a standard drawer in another model.

The slim shelf is a low (up to 5 cm) tray, which is the best suited for storing seasonings, rolled puff pastry, ice, butter, meat preparations and other small-sized products. In such a container, you can’t place products one on top of the other, so finding the right frozen item will be much easier.
