Description

Operating two-circuit automated water heating system according to an independent scheme with a heat exchanger in a modular floor design. The unit is autonomous, does not require connection to heat, water and sewerage networks, it can be freely moved indoors.
The unit is monitored and controlled by a controller for heating systems. Information from the unit can be transmitted to a PC placed on a console table for dispatch control and laboratory work.
The unit is designed to study the structure and principle of operation of an autonomous water heating system, experimental study of processes in the heating system, automatic and manual balancing of the heating system, and determination of the characteristics of heating devices.
It can be used for laboratory work on the courses «Heat Supply», «Heating and Heating Systems», «Thermal Engineering Measurements» and «Automation of Heating Systems» in higher, secondary and vocational educational institutions.
