This bachelor thesis is focused on design of ventilating and air conditioning of wooden apartment building. In theorethical part are discussed types of wooden constructions, then in the next part there is focus on inner elements such as: injurants made from outer and inner environment, calculation of room's thermal load, types of air conditionings, ways of heat obtaining and ending parts of ventilating and air conditioning systems where these elements are influencing a state of internal microclimate of buildings. Practical part is focused on a design of the of ventilating and air conditioning. It consist of a building dissection on functional parts, thermal balances, air flows and an air distribution into individual rooms, a noise absorptio...
