Comparisons and economical analysis of heating, cooling and ventilation installations in a building

The purpose of this thesis is to provide a source for mechanical installation systems while comparing the present systems with the systems of today?s improving technology.On the base point; this work was prepared because of my uneasiness for unlucky solutions due to the different approaches of system operators and purchasers.The primary reason for this unlucky system solutions is the purchasers approach of chosing the minimum costing investments.For the present building heating, cooling and ventilation installations were considered completely and compared with the alternative installations with in the same perspective.While comparing systems , net present value method was used among the economical analysis methods. Different from the recent works in this field, in this thesis calculations of the investment cost includes labor costs of installing. While getting at the conclusions sub costs like scrap value, maintenance costs were evaluated with the primary costs of fuel/electric consumptions.In the conclusion, advantages and disadvantages of the alternative systems were evaluated. In consideration with the system comparions suitable system solutions were examined.Although there is many publications on system solutions, there is no comprehensive publucations for designers without directing manner.This is also a source of purpose for the preparation of this document.Keywords: Heating, cooling, ventilation, economical analysis
