1. Optimization of air flow control process with the help of software and new measurement devices Paper author: Mg.sc.ing. Dmitry Ivancov Scientific supervisor: Dr.sc.ing., professor Arturs Lesinskis Riga, Latvia. 2012.

2. Introduction Nowadays construction rates are constantly increasing. New technologies are always developing and presence of engineering technologies in the field of construction gradually overweights construction technologies. Engineering networks and automatization systems become more complex. To install and set them up additional testings and check-ups of system operations are required. 2 Modern buildings incorporate more than 50 engineering systems. Technical facilities of buildings increase constantly. ESСТ ES СТ ES – engineering systems CT – construction technologies

3. Summary Key idea of this proposal is launching software based on algorithm developed by me. This software is designed for checking, testing, inspection, installation and regulation of aerodynamic systems. Main part of data entries and analytical tasks solutions will be done by using resources of personal computer and software, and measuring equipment should work as sensor to read off main information and as wireless data transfer device. 3 New product CO2 P, ∆P m/sek, m3/h °C, %RH The existing instruments

7. General opportunities of the program...CO2P, ∆Pm3/hm/sek%HR°C program The measurement summary

8. Optimization of the instrument Key aspects of instruments’ optimization: division of analytical and measurement blocs, connecting equipment with software. 8 Advantages: Easier and faster entering of data. Data is registered electronically. Number of errors is decreased. Only basic parameters are needed to conduct measurements (Pa, m/s, °C, %RH).
