Learning outcomes of the course unit
Students will gain essential knowledge of ventilation, air-conditioning
and heating systems, evaluation of indoor air quality and the means of
noise reduction.
Prerequisites
Basic knowledge of thermodynamics, heat transfer and fluid mechanics.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
One-day exam consists of both written and oral parts. Four questions (two theoretical and a practical two) are given. A personal calculator is required to solve the practical question; moreover,the examinee may bring and use their own literature. The overall exam evaluation equally accounts for both the theoretical and practical part.
Aims
The course objective is to make students familiar with basic concepts and techniques used for creating an optimal indoor environment. Students will learn of the design and operation of equipments of thermal and humidity comfort (heating/cooling/humidification/dehumidification), air cleanliness control, and means of noise reduction in working environment.
