dc fan

DC fans are fans that are powered by direct current (DC), as opposed to traditional AC fans that are powered by alternating current (AC). These fans are characterized by some advantages compared to AC fans, such as higher energy efficiency and the…

Decibel

Decibel (dB) is a logarithmic unit for measuring the proportional ratio of a physical quantity, such as sound intensity, power, voltage, or the intensity of an electromagnetic radio wave. It is used to express large differences in the values…

degree Celsia

Today, the Celsius scale (as a minor unit of the SI system) is defined by the triple point of water, which is assigned a temperature of 0.01 °C, and by the absolute magnitude of one temperature scale degree (±1 °C) being equal to…

dehumidifier

A dehumidifier is a device that is used to remove excess moisture from indoor environments such as rooms, bathrooms or warehouses. These devices are important for maintaining adequate indoor humidity levels, as excessive humidity can cause a variety…

demineralizácia
