How to calculate or where to look cooler Power

How do I know the power of the refrigerator?

to users of household appliances this issue does not become an impossible task, for more than ten years ago in Europe there was a law under which all the equipment has to be decorated with noticeable marks unambiguous designation of electricity consumed in a day or a year.Meaning, of course, indicates the average, but nevertheless, the specific energy consumption count refrigerator can accurately.

Another thing - the same classification level of energy efficiency.Previously, it was 7 symbols in the Latin alphabet: A, B, C, D, E, F, G, where A - the most economical technique, and the G - the most wasteful.Today were added to A +, A ++ and A +++, which improved performance A. One + is equal to minus 10% of consumption, two + -30%, + three mean minus 50% of consumption.However, the data to enter the classification list are averaged so that even two similar refrigerator, located in the same class may be very different if it comes to power consumption.

typical annual power consumption of a refrigerator in a year - the order of 400kW / h, although this value is very average.On electricity consumption affect the volume of the refrigerator, the lowest possible temperature in each of the cells, the presence of additional functions (samorazmorozka screen, ledegenerator etc.).

problem of calculating the power of the refrigerator

main difficulty to calculate the capacity of the refrigerator is the main energy-consuming element - Compressor - does not work all the time, and periods.In any refrigerator, from Saratov domestic and foreign Biryusa to Samsung Indezitov and Atlanta, Freon circulates exactly as long as the sensors do not celebrate the desired temperature, after which the device is switched off.Also complicate the task of asynchronous motors, which at the time of start can consume many times more watts of rated power.

What is the capacity of freezing?

This power, in contrast to the all electric understandable, designated in obscure kg / day.Many people mistakenly believe that this is the amount of ice produced by the machine.In fact, it supposed to freeze more dense and structurally complex products, so the measurements are made on the simulators - special parallelepiped packages with specially developed for such cases composition.In particular, there are included water ¾, 1/5 hard spoken emulsifier, salt and about 1/20 1/100 antiseptic.Packages are placed in a special way within the chambers, measuring how fast the liquid freezes and how long maintains the set temperature.Thus Refrigerators are separated into classes depending on the climatic conditions in which they will operate.
