Comparison Blaufisch BCF-22IL 198 L vs Heinner HCF-200CNHE++ 198 L

Unlike classic compressors, inverter compressors operate continuously, with the power changing depending on current needs. Freezers with an inverter compressor are free of the main drawback - regular switching on / off, which negatively affects the durability, energy consumption and noise of the device. On the other hand, such units are quite expensive.

The lowest temperature that the freezer can maintain in normal operation. First of all, the duration of food storage in the freezer depends on this parameter: it is believed that a temperature of -12 ° C is enough to preserve food for a month, -18 ° C – 3 months, -24 ° C – up to a year. At the same time, it must be taken into account that not only temperature affects the shelf life but also the type of product and its quality before freezing.

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.

It is the forced freezing mode, in which the temperature inside the freezer is briefly reduced to -24 °C. This mode is intended for the case when you need to freeze numerous products at the same time — without a sharp decrease in temperature, the heat from numerous non-frozen products could lead to its critical increase.
Usually, the fast freeze mode must be turned on in advance — 5 to 6 hours before loading the products. Thus the freezer has time to decrease the temperature in the chamber. In this case, it is necessary to take into account the increased load on the compressor — it is impossible to turn on fast freeze for a long time. In some models, automatic shutdown of the fast freeze mode is provided. In some, it must be done manually.

Freezer interior lighting system. This function is very helpful given that the working chamber of the unit, even with the door open, is often shaded, and it is not so easy to see its contents. The lighting usually works automatically — similar to how it is implemented in refrigerators: the light turns on when the door is opened and turns off when it is closed.

If a child lock provides for electronic locking of controls, then mechanical lock is a lock for the door, which can be opened with a key. This solution is in high demand in chest freezers intended for non-domestic use.

A handle made in the form of a notch at the end of the door. Thanks to the hidden handle, the freezer at least gets a neat, discreet appearance — with a minimum of unnecessary details on the doors. In addition, a traditional handle can be touched by careless movement, but with a hidden one, it is impossible. It is especially relevant in cramped conditions.

The energy class shows how economical the freezer is in terms of electricity consumption. Initially, the classes were designated in Latin letters from A (most economical) to G (high power consumption). Recently, improved classes A+, A++ and A+++ appeared (the more pluses - the more economical the device).

It should be borne in mind that this indicator represents not the actual energy consumption but the efficiency of the unit compared to similar models. Therefore, a small class A freezer may have a lower power consumption than a large class A++ model. And other things being equal, a more economical device, as a rule, costs more, but this difference can quickly pay off during the operation.

This parameter shows the efficiency of electricity consumption by the freezer. Classes are designated in Latin letters from A to G, in ascending order of energy consumption. It was originally conceived until more energy-efficient models pulled up to class A, which eventually received the marking A+, A++, and A+++. Further development of technology has made it possible to go even further and, in order not to produce pluses in energy efficiency labelling, in March 2021, manufacturers returned to the previous indices from G to A, where A is the most energy-efficient freezer. Accordingly, the 2021 models will have modern markings, while older models will be marked the old way.
