Description of the spin classes of washing machines, which is better in terms of efficiency
The spin class in the washing machine is the main parameter that determines not only the number of revolutions and the percentage of moisture in the laundry, but also the level of electricity consumed. All manufacturers of these household appliances adhere to European standardization and designate the class with a Latin letter. Knowing these parameters will help you make the right choice for future washing machine owners.
Classification principles
When developing the classification, the number of revolutions, rotational force, mass difference and residual moisture were taken into account.
How to calculate efficiency at home
In order to calculate the productivity of spinning at home, you need to weigh the already spun laundry, then dry and weigh it again. After that, you need to perform a fairly simple calculation: the resulting weight of the already dried laundry is subtracted from the weight of the wet laundry.
The result obtained must be divided by the weight of the dry linen, then the whole is multiplied by 100%.
For convenience, you can follow this example: if immediately after washing the laundry weighed 5 kilograms, and after drying it has already become 3 kilograms, the result of the calculations will be the number 2. It must be divided by 3 and you get 0.66. Multiplied by 10, that gives 66%.
Decryption
The higher the power of the washing machine and the more revolutions the motor makes, the higher the class assigned to it. According to the European quality standard for drying laundry, the Latin letter "A" denotes the high-quality spin class, and the letter "G" - the lowest. Each model is assigned a specific designation.
"G"
The device operates at 400 rpm, the remote humidity percentage is 10. Today, units of this category are practically not produced, since they have extremely low performance.
"F"
The washing machine guarantees 600 rpm, the device of this category removes moisture by 20%. Similar washing machines are practically not produced.
"E"
The drum rotates at 800 rpm, and this category of washing machine removes humidity by 25%.
"D"
The rotation speed of the centrifuge is 1000 rpm, the percentage of moisture removed is 30 (that is, about 65-70% moisture will remain in the laundry).
"VS"
The speed of such a household unit is 1200 rpm. The machine is capable of removing moisture by 40%.
"B"
The washing machine provides a speed of 1400 rpm, a device of this category removes moisture by 45%.
"A"
The appliance guarantees dry spinning and a minimum of residual humidity. The rotation speed of the centrifuge is 1600-1800 rpm, the percentage of moisture removed is 55%.
How not to make a mistake when choosing
Considering that a washing machine is bought for more than a year of use, it is better to familiarize yourself with all the characteristics of the selected equipment before buying it. Experts assure that the centrifuge in the washing machine should remove at least 40% of moisture from things, therefore, devices of category "A", "B" and "C" are favorable options.
The choice of the preferred household unit directly depends on the specifics of the laundry to be washed and financial capabilities.
Optimal speed settings for different materials
Not all materials can be washed as standard. For some types of fabrics you will need a mode such as delicate wash. As a rule, on modern models of washing machines, you can set the required number of revolutions. Too fast rotation of the motor can damage certain fabrics.
Linen, jeans, cotton, large calico
For denim and cotton fabrics, the allowable value is 800 rpm. It is also recommended to activate the delicate wash cycle. Linen is an extremely delicate material, so the spin is either deactivated or activated at the minimum number of revolutions.
satin, silk
Satin, silk and tulle items should be washed at 600 rpm, as they are rather fine and delicate materials. If there is such an opportunity, then the spin is disabled.
Wool
It is not recommended to wring woolen items. If there is no such option, it is recommended to set the minimum spin value (no more than 400 rpm).
Effect of spin on energy consumption
It is important to take into account that the spin class of the washing machine directly affects energy consumption. Appliances of class "E" and lower are capable of consuming a lot of electricity with a low quality of spin.
Although the machine is of a superior class, although it consumes the maximum power, it provides the best spinning.
Experts recommend buying washing machines with spin class "B" - they have good spin quality and do not consume a lot of electricity.
Advice to future owners
When choosing a washing machine, it is recommended to take into account not only the spin class, but also other main characteristics: water consumption, energy consumption, number of modes, manufacturer. If the main requirement is electricity consumption efficiency, you should choose the A++ class household appliances. However, for those who prefer to dry their clothes in the fresh air (courtyard of a private house or balcony), the spin class will not have priority value - you can safely take a washing machine wash with a spin class lower than "B".
However, it should be borne in mind that things that are not completely wrung out when wet become heavier (this is especially true for terry towels, blankets and blankets).The owner of a low-spin washing machine will have to make extra efforts each time to get the laundry out of the drum and send it out to dry. If there are prohibitions on such effects on fabrics, it is recommended to purchase a household unit that will provide the possibility of dry washing.
