The Faculty of Automation and Computer Engineering of Novosibirsk State Technical University (NSTU) has developed algorithms for controlling a heat recovery unit, a ventilation system that preserves useful energy while controlling warm or cold air flows.
The ventilation system, which uses a heat recuperator to partially return energy from the exhaust air, has proven itself well not only in enterprises, but also in residential areas. In the cold season, the equipment uses the heat of the outgoing air to heat the incoming air, as a result of which the temperature in the room does not require significant heating; in summer, the system works the other way around. Thus, a comfortable climate is constantly maintained in the room without high costs for heating and air conditioning.
A few years ago, one of the main suppliers of recuperation systems to the domestic market was a Swedish company, now they are developing recuperators in Russia. According to Alexander Yakimenko, Head of the Department of Computer Engineering at the Faculty of Automation and Computer Engineering of NSTU-NETI, one of the university's industrial partners designed a system for residential premises and came up with a proposal to develop control algorithms.
The staff of the Computer Engineering Department, namely Associate Professor Evgeny Romanov, senior lecturer Sergey Menzhulin and assistant Igor Dyminsky started to solve this problem. "Currently, we are working with one of the prototypes in the laboratory, dealing with the hardware component, the selection of pressure, temperature, humidity, CO2 level sensors and device programming, configuring the UNIX environment and developing applications, and connecting students," said project administrator Alexander Yakimenko.
According to the developers, a heat exchanger is not only a heat exchanger, fans, filters and an air outlet, it is also a system that must monitor the operation of all components and air quality, diagnose the condition after a possible power outage and respond to the user's request to choose one mode or another. It will be possible to control ventilation remotely — NSTU-NETI has developed an application for all devices.
Earlier, AUTF employees repaired an imported ventilation system at the Novosibirsk Special Music School. We had to deal with the control module of the Swedish air treatment plant, which has been operating since 2012.
