Item ИЗСЛЕДВАНЕ НА ЕФЕКТИВНОСТТА НА PV СИСТЕМИ ЗА БИТОВО ГОРЕЩО ВОДОСНАБДЯВАНЕ(Бургаски свободен университет, 2022) Йовков, Атанас; Лецковска, Силвия; Сейменлийски, Камен; Долчинков, Радостин; Симионов, РадославThis report presents an analysis of the results obtained from a study of the efficiency of photovoltaic systems for domestic hot water supply. The performance of a solar photovoltaic water heating system with direct coupling of a photovoltaic array to a DC resistive heating element is studied and compared with a solar photovoltaic system. The analysis was carried out under the same climatic conditions for both systems.Item АЛГОРИТЪМ ЗА ТЕЛЕМАТИЧЕН МОНИТОРИНГ НА ЕЛЕКТРИЧЕСКИ АВТОМОБИЛИ(Бургаски свободен университет, 2022) Венциславов, Кристиан; Сейменлийски, Камен; Лецковска, Силвия; Моллова, СтоянкаСтатията представя общия принцип на работа на конкретен авторски алгоритъм, който е внедрен в реално работеща телематична система за електромобили.Item ИЗСЛЕДВАНЕ ВЛИЯНИЕТО НА ШУМА В РАБОТНА СРЕДА ВЪРХУ ЕКИПАЖА НА КОРАБ(Бургаски свободен университет, 2022) Орешков, Кольо; Долчинков, Радостин; Лецковска, Силвия; Сейменлийски, КаменThis document presents the study results of the ships working environment factors, in specific – the noise, produced by different kind of machines and the influence on the ship's crew. Measurements and tests are carried on a cruise vessel. Certified devices are used, which are described in the exhibition.Item ПРОИЗВОДИТЕЛНОСТ И ЕНЕРГИЙНА ЕФЕКТИВНОСТ НА RASPBERRY PI БАЗИРАН КОМПЮТЪРЕН КЛЪСТЕР(Бургаски свободен университет, 2022) Моллова, Стоянка; Лецковска, Силвия; Орешков, Кольо; Заеров, Елдар; Лодкаджиев, КристиянA cluster structure of single-board Raspberry Pi microcomputers has been implemented. Laboratory studies and analysis of performance and energy efficiency characteristics for the created cluster have been carried out.Item ИЗСЛЕДВАНЕ НА ПОВЕДЕНИЕТО НА ХИБРИДНАТА ЕЛЕКТРИЧЕСКА СИСТЕМА НА КАТАМАРАН ПО ВРЕМЕ НА МОРСКИ ПРЕХОД(Бургаски свободен университет, 2021) Георгиев, Гинко; Лецковска, Силвия; Долчинков, РадостинThis report examines a hybrid propulsion system for a sea vessel for tourist trips. The behavior of the system during the sea transition - charge and discharge of batteries, energy production, etc. Was studied.Item ПРИЛОЖЕНИЯ НА СЪВРЕМЕННИТЕ ДРОНОВЕ В ТРАНСПОРТНИТЕ ТЕХНОЛОГИИ(Бургаски свободен университет, 2021) Драгнева, Николина; Долчинков, Радостин; Лецковска, Силвия; Сейменлийски, Камен; Георгиев, ГинкоDrones have been around for years, are used for a variety of purposes, and can be helpful in a number of cases. However, these devices have become more popular and more affordable in recent times and their applications in various fields are growing rapidly. Their use in transport technologies is possible for both freight and passenger transport and is a way to reduce environmental pollution and traffic safety.Item ИЗСЛЕДВАНЕ ПРИЛОЖЕНИЕТО НА МИКРО ВЕИ ЦЕНТРАЛИ ЗА СГРАДИ С ПОЧТИ НУЛЕВА КОНСУМАЦИЯ НА ЕНЕРГИЯ(Бургаски свободен университет, 2021) Лецковска, Силвия; Сейменлийски, Камен; Симионов, РадославIn 2010, the Energy Performance of Buildings Directive 2010/31 / EU (EPBD) was adopted, which states that from 31 December 2020, all new buildings in the EU must be constructed as buildings with almost zero energy consumption. Nearly zero or very low energy needs must be covered to a large extent by energy from renewable sources, including energy from renewable sources, produced on site or near the building. Achieving zero energy consumption is not possible in all buildings. For school buildings, however, the goal of net zero consumption is feasible. The report presents research aimed at reaching zero net consumption for the BSU building. Results for production of energy from a photovoltaic power plant for own needs, located on the roof of the university, realized modularly using photovoltaic panels of different types are shown.Item БУРГАСКИ СВОБОДЕН УНИВЕРСИТЕТ – ПРОИЗВОДИТЕЛ НА ЕНЕРГИЯ(Бургаски свободен университет, 2015) Заеров, Елдар; Сейменлийски, Камен; Лецковска, СилвияIn recent years, with increasing requirements of the European Union for reducing harmful emissions and increasing energy efficiency in public buildings and industrial systems increasingly topical issue is the problem of the generation of electricity from its own power plants using renewable energy sources. The purpose of this work is to present part of the results that the collective has received in studies of the potential for electricity production from the roof of Bourgas Free University.Item МОДЕЛ НА ВЪЛНОВ ПРЕОБРАЗУВАТЕЛ ЗА ДОБИВ НА ЕЛЕКТРОЕНЕРГИЯ ОТ ЧЕРНО МОРЕ(Бургаски свободен университет, 2021) Долчинков, Радостин; Лецковска, СилвияThe present work aims to assess the energy resources of the waves in the Black Sea basin. The study focuses on the use of the wave energy potential in the Black Sea coastal zone. Based on the analysis of the different technologies for the conversion of energy from sea waves, a classification of the different wave converters is made. As part of the study, a real model of a wave converter was made, which combines two ways to drive the working body of the converter.Item ПЕРСПЕКТИВНИ ТЕХНОЛОГИИ ЗА ОПОЛЗОТВОРЯВАНЕ НА МОРСКИЯ РЕСУРС(Бургаски Свободен Университет, 2020) Лецковска, Силвия; Сейменлийски, Камен; Заеров, Елдар; Симионов, РадославThis article discusses the desalination of sea water. The focus is on the use of renewable energy for the desalination of sea water. Existing desalination plants from the Black Sea have been studied.
