Comparison Whirlpool ART 9812 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 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 work 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.

A deodorizer is a device that eliminates unpleasant odours in the refrigerator caused by spoiled food or products with strong smells. It purifies the air inside the fridge, preventing foreign odours from being absorbed by other products. This is important as some foods have a tendency to absorb strong odours, which can spoil their taste and quality.

The lowest temperature provided by a refrigerator freezer.

The lower the freezer temperature indicator, the more advanced the freezer is considered to be, and the better it is suited for long-term food storage with wider capabilities. It's important to note that the standard operating temperature for a fully functional freezer is -18 °C, which is suitable for both storing and freezing pre-frozen foods. Some refrigerators are designed with a temperature indicator of -24 °C, but this is mainly achieved through the quick freezing mode (see "Functions"), and the standard operating temperature is still -18 °C. However, if you plan to freeze food frequently and store it for extended periods, it's better to choose a model with a temperature of -24 °C and consider the freezing power as well.

Less expensive refrigerators have a less advanced freezer with a modest minimum temperature of -12°C or even -6°C, which is only suitable for storing pre-frozen foods, not for freezing fresh food. Although they are much more affordable.

To indicate the temperature of the freezer, markings in the form of asterisks (snowflakes) are often used, each of which means a decrease in temperature by 6 °C. For example, the mentioned -18 °C will correspond to 3 asterisks (***).

The freezing capacity of a refrigerator refers to the amount of fresh food it can freeze from room temperature to the freezer temperature within a 24-hour period. For everyday use, a freezing capacity of up to 10 kg/day is sufficient, but if you frequently freeze large volumes of food, you should consider a more powerful freezer.

The forced freezing mode briefly lowers the temperature inside the freezer to as low as -24 °C or -32 °C. This fast freezing function needs to be turned on in advance and has a limited operating time. Some models do not have automatic shutdown, so it's important to clarify these details. It's worth noting that drawers or quick-freeze zones are not considered as this function.

The energy class that the refrigerator corresponds to.

Energy consumption classes were originally designated with Latin letters from A (the most efficient) to D (least efficient), but with technological advancements, more advanced classes such as "A+", "A++", etc. were introduced to indicate increasing levels of efficiency. The more pluses a device has, the more economical it is. This was necessary due to the correlation between energy consumption and decreasing efficiency.

For modern built-in refrigerators, the efficiency indicator at the level of class A can be called average, A+ — not bad, A++ — good, A+++ — excellent. Energy consumption rates B and C are rare and mostly found in outdated or cheaper models. Achieving high efficiency requires design innovations, which results in higher device prices. However, these prices can be justified by the resulting reduction in electricity bills. It's worth noting that some built-in refrigerator models are available in different energy consumption classes, allowing customers to choose the best option for their budget and energy efficiency needs.

The average amount of energy consumed by a refrigerator in a year of operation.

The given parameter is an estimated value and assumes that the refrigerator operates under stable conditions without sudden temperature changes, frequent door openings, and within its designated climate class (see below). Actual energy consumption may deviate slightly from the stated value. Despite this, it is a useful parameter that allows for a rough comparison of different models in terms of energy efficiency.

It should be noted that the energy consumption per year is often a more practical and convenient parameter than the energy consumption class (see above), which is a relative indicator of how efficient a refrigerator is compared to other models of similar size and features. The energy consumption per year, on the other hand, provides an estimate of the actual electricity cost when using a particular refrigerator. For instance, a small two-door refrigerator with an energy class of A can consume less energy per year than a large side-by-side refrigerator with a class of A+++, despite the fact that the latter is formally more energy-efficient than the former in terms of its energy class.
