Heating engineering

Central heating is a type of heating in which heat is produced in one central place and carried by water or air through a pipe network to distribution elements (air) or to radiators (water).

This group covers equipment for treating air in ducted heating and air distribution systems.

A heat substation provides a controlled exchange of heat energy between the primary network and the secondary heating network of individual residential buildings. It consists of a primary and a secondary part, joined by a heat exchanger into a single thermo-technical unit.

A boiler room is part of most technological processes. It is used in the metal and processing industries and in the food, textile, chemical and other industries. Boiler rooms of small, medium or large capacity serve as stand-alone units for heating residential buildings or production plants, and for preparing the hot water that many technological processes need. Whatever their capacity, boiler rooms share the same operating principle and components.

Technologically, a boiler room has two parts: a system that produces heat energy and a system that distributes it. In these systems various process variables have to be kept at set values: water temperature and level, fuel temperature and level, air pressure, fuel flow and others.

Automatic control means running a process on the principle of negative feedback, without a person present. The controller acts on the difference between the input reference value and the control value. The control deviation determines the control value through which the final control element acts on the process. The type of control is chosen in relation to the reference value.
