In the technical and engineering context, "radial" refers to the direction from the center outward, or from the center to the edges or outside. The term is often used to describe a characteristic of movement, an arrangement of components, or…

Radiant ceiling heating

Radiant ceiling heating is a type of heating system that uses the law of radiant heat exchange between a warmer body and a cooler environment to transfer heat to the interior of a room. This system is often installed in the form of panel, pipe or…

Radiant panels

Radiant panels, also known as infrared radiant panels, are technological devices that produce heat using infrared radiation. These panels use the principle of electromagnetic radiation to heat objects and the space around them. Infrared radiation…

radiator

A radiator is a body that serves to transfer heat from one medium to another for cooling or heating. The radiator is used for heating rooms and spaces. It is made of materials that conduct heat well. They are designed in such a way that, if…

radon

Radon is a colorless, tasteless, and odorless radioactive gas that occurs naturally in the earth's subsoil as a product of the decay of uranium rocks. It is considered a natural source of ionizing radiation, which means that exposure to it…

Rated heat output

Rated heat output is a term used in connection with heating devices, especially boilers and heat pumps. It means the heat output that the device is capable of delivering under standard operating conditions. The rated heat output is given in…

recovery

Recovery - a controlled ventilation system clearly contributes to healthier living and has an indisputable number of advantages. The recovery system distributes clean air free of impurities to all parts of the building, extracts odors from areas…

reducing valve

A pressure reducing valve, also known as a pressure regulator, is a device used to reduce the pressure of a gas or liquid in a pipeline to a desired value. Its main function is to maintain a constant outlet pressure even as the inlet pressure…

reduction

Use of reducing valves: Water systems: Pressure relief valves are often used in homes and buildings to reduce the pressure of potable water from the public water supply to a suitable level for domestic use. Gas systems: In gas systems, pressure…

Refrigerant R32

Refrigerant R32 is a mixture that belongs to the group of fluorinated hydrocarbons (HFC), which is used as a refrigerant in air conditioning and refrigeration systems. It is a component of many modern air conditioning units and is increasingly…

regulation

Regulation or regulation can be: in general: controlled intervention, adjustment, guidancein biology: a set of physiological processes maintaining the constancy of the organism's internal environment (temperature, pressure, water, etc.), see…

regulator

A regulator is a device that ensures that a given system works automatically and operates within the required range of values. A controlled system can be, for example, an engine, an electric motor, heating, air conditioning, a chemical process,…

regulatory screwing

  Control screwing in heating refers to the use of control valves that are screwed into heating circuits at various points in the system. These valves enable manual or automatic adjustment of the flow of hot water to individual heating…

relative roughness coefficient

The relative roughness coefficient, also referred to as the pipe roughness coefficient or absolute roughness, is a physical quantity that is used to characterize the surface of the inner walls of pipes, tubes and channels. It expresses how the…

remote control

Remote control is a technological system that enables control and management of devices or systems remotely, without the need for direct physical contact with them. It is a means that allows a user to control and manipulate the functions and…

Renewable energy sources

Renewable energy sources (RES) are energy sources that can be regenerated or renewed in a short time horizon. This means that their use does not exhaust these resources and does not contribute to their depletion. RES are a key factor in efforts for…
