HEATING SYSTEM SIMULATOR – didactic equipment
The simulator must allow the study, the performing of experiments and the troubleshooting for the following systems:
•
Central heating system;
•
Heating system with distributed regulation;
•
Zone heating system.
These systems must be reproduced on the panel, through a colour representation which allows a complete analysis of
the fluid circuit, of its components and of the electrical/electronic circuit for control and regulation.
It must be possible to simulate the behaviour of components and systems, on the basis of the operating conditions
which will be monitored directly on the Personal Computer.
The central heating system must be composed of the following main elements:
•
Liquid or gas heat generator;
•
Forced circulation circuit, two pipes, with closed expansion tank and inverse return;
•
Electronic central regulation of the delivery temperature, on the basis of the external temperature, trough
three- way mixing valve;
•
Re-circulation anti-condensate pump;
•
Boiler regulation thermostat and block thermostat;
•
Block pressure switch and safety valve;
•
Fuel interception valve.
The heating system with distributed regulation must be composed of the following main elements:
•
Gas heat generator;
•
Forced circulation circuit, single pipe, with closed expansion tank and inverse return;
•
Regulation distributed on each user, through:
•
Two-way thermostatic valve;
•
Three-way thermostatic valves;
•
ON/OFF thermostats
•
Boiler regulation thermostat and block thermostat
•
Block pressure switch and safety valve;
•
Fuel interception valve.
The zone heating system must be composed of the following main elements:
•
Gas heat generator;
•
Forced circulation circuit, zone type, with closed expansion tank and direct return;

The trainer must be specially designed in vertical frames, bench-top, so as students can watch the theoretical and
practical study of the thermotechnics area . The simulator must consist of a panel operated by a PC with a coloured
diagram that should clearly show the structure of the system and should allow the location of components on it. The
display of the information available on the PC screen must allow the continuous control of the educational system and
shall display its behaviour through analog and digital signals and meters. The operational conditions must be entered
by the students. The insertion of faults must be carried out through the PC.
The trainer must be supplied with the software and the documentation that shall guide the student to the study and
the performance of the simulation exercises.
The scheme must utilize the symbols specified by the DIN regulations
The simulator panels must be made of fire varnished metal covered by a coloured polyester glue 150μ 3M7962. The
front panel must have the RAL colour 1007 and schematic diagram. External dimensions: 1041 x 690 x 150 (470 with
the base) mm.
All components and leads must be made to protect the safety of the students according to the laws in force.
It must be provided with manual in English language.
