The student must be able to:

• set up the mass and energy balance of equipment and calculate the heat duty, log-mean temperature difference and heat transfer area of a heat exchanger,
• calculate heat transfer coefficients, the overall heat transfer coefficient and the pressure drop for flow in pipes and tube bundles,
• calculate fuel combustion (air demand, flue gas amount and composition),
• describe the construction of basic process equipment (heat exchangers, pressure vessels),
• work with thermodynamic properties of substances and mixtures and convert SI units,
• process balance measured data and determine the measurement uncertainty.

These skills are acquired in Heat Transfer Processes, Hydraulic Processes, Engineering Thermodynamics, Energy and Emissions, Design of Process Equipment I and Balancing of Process and Energy Systems, which students have completed.

The course is completed by an examination (ECTS grading scale). Course-unit credit from the exercises is part of the assessment. The course-unit credit is a prerequisite for taking the examination.

Lectures: attendance is optional (recommended).

Exercises: attendance is compulsory and checked by the instructor at every class. Two absences are allowed without making up. Every further absence must be duly justified and the student solves the problems that were missed; a missed part of the project-based teaching is made up by arrangement with the instructor.

Course-unit credit requirements:

1. regular and active attendance at the exercises,
2. completion of all problems assigned in the exercises,
3. submission of the measurement report from the project-based teaching, in which each team member orally explains his or her part (verifies learning outcome 5).

The examination has two parts:

1. Written part: calculation problems on equipment design (verifies learning outcomes 1–4), maximum 30 points. A student who obtains at least 50 % of the points, i.e. at least 15 points, proceeds to the oral part.
2. Oral part: a professional discussion with the examiner following up on the results of the written part, verifying theoretical knowledge from the lectures (in particular learning outcome 6), maximum 20 points; passed with at least 10 points.

Final classification: the sum of points from the written and oral parts, maximum 50 points. A: 45–50, B: 40–44, C: 35–39, D: 30–34, E: 25–29, F: 0–24.

Upon completion of the course, the student is able to:

1. select a suitable type of heat exchange equipment (tubular, plate, regenerative of the static or moving type) for a given application in a process or power system and carry out its technological and dimensional design in the given design phase (conceptual design, feasibility study, basic design),
2. set up the balance of equipment with phase change of one working fluid and of a multi-stage system of equipment with phase change of both working fluids, determine the optimal operating parameters of the equipment in the individual stages and carry out their design in a professional program,
3. select a suitable type of combustion equipment (process furnace, boiler) for a direct or indirect heating system and design its main (overall) dimensions with regard to safe and reliable operation,
4. set up a simple model of the transient operation of equipment, quantify the effect of transient operation, fouling of heat transfer surfaces and heat losses on the size and operational safety of the equipment and include them in the design,
5. design, in a team, the layout of a measuring section for determining the thermal-hydraulic characteristics of an additively manufactured TPMS element, evaluate the measured data (heat transfer coefficient, pressure drop) and prepare a measurement report,
6. describe the design stages of process and power systems (conceptual design, feasibility study, basic design), the procedure for the dimensional design of fired heaters (process furnaces and boilers) and the principles and techniques of the design of integrated equipment.

Lecture presentations, exercise problems, project materials and guides to the software used are provided by the instructors continuously during the semester in the course e-learning (Moodle), on a shared drive or in the course group in MS Teams; the environment is agreed between the instructors and the students at the beginning of the semester. Enrolled students have access to them.
