VidEB001 [GVIEB001] Maintenance of Heating Systems
Course abstract
The aim of the study course is to acquire the design and maintenance of building heating systems with water, hot air, electric heaters, gas heaters, heated floors and their component parts as well as heat generators and installation elements. The design of up-to-date heating systems, control principles and it's components are analyzed as well as solutions to improve energy efficiency.
Learning outcomes and their assessment
Knowledge - the construction and operation of heating systems and component parts, operation providing elements, maintenance;
Skills - to be able to calculate the components of heating system, to make reasoned choice of working conditions and to evaluate those suitability for object;
Competence - to choose the most suitable heating system for the given object, to evaluate solutions of the heating system operation and control energy efficiency improving.
