acetylene

Acetylene (ethine) is a hydrocarbon belonging to the group of alkynes. Its chemical formula is C2H2, which means it consists of two carbon atoms and two hydrogen atoms. It is a colored and colorless gas with a specific smell. Acetylene is known for…

Acids

  Acids, also called acids (commonly referred to as HA), are chemical compounds whose aqueous solutions have a pH lower than 7.0. This definition is an approximation of the modern Brønsted-Lowry concept, which defines an acid as a substance…

acoustic pressure

Acoustic pressure is a physical quantity that describes the pressure of sound waves on a surface. It is a change in pressure caused by the fluctuation of the molecules of the medium in which the sound propagates. Acoustic pressure is one of the key…

active cooling

Active cooling is a method of removing heat from various devices and systems using active components such as fans, pumps or compressors. These components supply external power to increase the flow of the cooling medium, ensuring efficient heat…

actuator

An actuator is a mechanical or electrical device that changes a signal or energy input into a physical movement, action, or effect. Its main purpose is to convert a control signal into a physical action or change in a certain system. Actuators are…

adapter

  ELECTRONICS In electronics, the term "adapter" is used to refer to a device or component that is used to convert, connect, or adapt one type of connector, interface, or voltage to another. Its main function is to enable…

aerator

An aerator is a small attachment placed at the end of the outlet opening of a water fitting, such as sink faucets, shower heads or faucets. Its main function is to mix the stream of water with air and thus create the so-called "pearl" effect.…

air condition

Air conditioning (denoted by the abbreviation AC from the English air conditioning) is the modification of the quality parameters of the air in closed spaces or a device (a system of devices) for such modification and distribution of such modified…

Air conditioning without an outdoor unit

Air conditioning without an outdoor unit is referred to as "outdoor air conditioning" or "monobloc air conditioning". This type of air conditioning system has all the necessary components for cooling or heating built into one unit located inside a…

Airtightness

Air tightness is the property or ability of a material, structure or system to minimize the penetration of air through unwanted gaps, cracks or fissures. It is an important factor in construction and the energy efficiency of buildings, as impaired…

ALC

In the context of thermostats, the abbreviation "ALC" stands for Automatic Limit Cooling. ALC is a function or mode present on some thermostats that provides indoor cooling or air conditioning control. This function allows the user to set the…
