Course abstract
The aim of the study course is to acquire the design, operation and choice of building heating systems and their component parts as heat generators, pumps, pipes, safety and installation elements. Electric heating systems, heating with gas heaters, heated floors with water pipes and electric heating cables, heating with hot air are acquired. The design of up-to-date heating systems, control principles and it's components are analyzed.
Learning outcomes and their assessment
Knowledge - knows types of building heating systems and the design and operational principles of their elements, selection criteria, systems management principles – tests 1 and 2;
Skills - calculation of the parameters for the elements of the heating system, making their reasonable choices, assessing their suitability for the site - test 1 and 2;
Competence - calculation and selection of the the heating system type and its elements suitable for a given object, assessment of the operation and control of the heating system, development of improvement solutions - tests 1 and 2.
