Nioise level (drying cabinet)

Ensure that drying cabinet supplied under the contract meet the noise level requirement. This can be done, for example, by checking product specification.

Energy consumption is often shown in kWh/X kg of laundry, where X represents the amount of clothes the cabinet is capable of drying at one time. Energy consumption is sometimes given in kWh/year. This number is often calculated according 200 uses, but ask the supplier in such cases to show how they convert to kWh/kg of laundry.

An energy-efficient drying cabinet that uses, for example, heat pump technology is more expensive to purchase but the more efficient energy consumption results in lower operating costs. A calculation should be made to ascertain the combined purchase and operating cost.

Example calculation

Assume that the drying cabinet will be used 200 times per year and that the price of electricity is 1 SEK/kWh.

The cost over 10 years = initial purchase price + annual consumption × price of electricity × 10 (years).

Drying cabinet 1:

Purchase price: 15,000 SEK.

Energy used to dry 4 kg of laundry: 1.3 kWh/load, which equates to 520 kWh/year.

Total cost, including purchase and 10 years of operation: 15,000 + 520 × 1 × 10 = 20,200 SEK.

Drying cabinet 2:

Purchase price: 6,000 SEK.

Energy used to dry 4 kg of laundry: 6 kWh/load, which equates to 2,400 kWh/year.

Total cost: 6,000 × 2,400 × 1 × 10 = 30,000 SEK.

Noise level or noise does not have an environmental impact, but it affects the work environment or the sound environment in the home. The sound that is not desirable for a listener is called noise. Noise can be harmful to hearing, disturbing, cause different physiological reactions and cause sleep disturbances. It can also make work tasks more difficult to perform and thus impair work performance. Therefore, noise level requirements when appliances are procured for use in workplaces as well as for use in households in new construction and similar are important.
