Comparison Liebherr IGS 1624 vs Liebherr IGN 1664

It is the total working capacity of the freezer. A larger capacity allows you to accommodate more products but affects the dimensions and cost of the unit. Therefore, when choosing according to this parameter, you should not chase after the maximum capacity but the capacity you really need. For example, the average required capacity is 50 litres per person. And when choosing a display chest freezer (see "Product type"), you need to take into account the number of products offered for sale.

It is also worth considering that the freezer is often divided into several compartments (see below) - which means that a large capacity does not guarantee that large pieces of food can fit in the device.

No Frost system inside the freezer. A special fan provides air circulation, while moisture condenses in the frost, not in the working chamber, but in a special compartment. Periodically, the fan turns off, the frost melts, and the meltwater flows into a special tray, from which it evaporates. Such a system eliminates the need to defrost the freezer to remove frost periodically. On the other hand, it imposes special requirements on the packaging of products, since in such freezers the products dehydrate fast.

The amount of time the freezer keeps food cold enough when the refrigeration system is turned off, for example, due to a breakdown or power outage. Technically, the power failure autonomy for each model is calculated differently; For example, for a freezer with an operating temperature of -18 ° C, this is the period during which the products in the chamber heat up from -18 ° C to -9 ° C. To sum up, the time is indicated during which the frozen products are guaranteed not to heat up to a temperature at which they could lose their properties.

The door auto-closer is responsible for “pulling” the door when closing, and in some models also when opening. The idea is that the user does not need to close/open the door completely: pull it to the right place, and then the door will be "picked up" by the auto-closer and smoothly brought to a fully open or closed state. Such a system performs two functions. Firstly, it reduces the risk of leaving the freezer not closed. Secondly, such a device provides a very smooth opening and closing without shock. Thus it has a positive impact on the life span of the entire device.

The presence of removable refrigerants (cold accumulators) in the freezer design. This solution allows you to extend the temperature retention time in case of a power outage and also allows you to take it with you for use outside the freezer if necessary.

It is the average amount of energy consumed by the freezer in a year of operation. Of course, these figures are not absolutely accurate. The actual power consumption may vary depending on the specific operating conditions. However, this parameter makes it possible to evaluate the consumption of the device and compare different models with each other. At the same time, it often turns out to be more convenient and visual than the energy consumption class (see above) because, in this paragraph, we are talking about a specific figure (from which you can also calculate the cost of electricity consumed).

The average noise level generated by the freezer during operation. The quietest models give out about 25 - 30 dB — this is the average noise background in a residential area at night (comparable to the ticking of a wall clock); the loudest — is about 60 dB (loud conversation). More detailed comparison tables can be found in special sources.

In any case, the lower the noise level, the more comfortable the use of the unit. However, it does not always make sense to look for the quietest freezer: in some situations (for example, in a noisy workshop), the freezer's sound may be lost against the surrounding noise background. In addition, reduced noise often affects the price.

— Sliding hinget. A sliding hinge involves the connection of a decorative panel with a freezer door using movable guides. So, with the sliding hinge, the front decorative facade is equipped with its hinges, and the freezer door is practically not loaded by the panel. On the other hand, with this type of hinge, there is a small gap between the decorative panel and the freezer door, in which dust can accumulate. Additionally, the sliding hinge does not allow the freezer door to be opened more than 90-95˚.

— Fixed hinge. With a fixed hinge, the panel is hung on the freezer door. It is the easiest and fastest option for installing the decorative panel. The fixed hinge assumes that the decorative panel loads the door hinges of the freezer. When choosing the fixed hinge for the panel, it should be taken into account that if the door of the freezer is not sufficiently reliable, the door of the built-in unit may be overloaded. Most often, the fixed hinge of the panel is used when installing a relatively small freezer. The compact panel is unlikely to overload the freezer door.
