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 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 МЕТОДИКА ЗА ДЕЙСТВИЯ НА ПРОТИВОПОЖАРНАТА СЛУЖБА ПРИ ИНЦИДЕНТ С ЕЛЕКТРИЧЕСКИ АВТОМОБИЛ(Бургаски свободен университет, 2022) Долчинков, Радостин; Сейменлийски, Камен; Попов, ИванThe methods and actions that the fire services must follow in order to deal with cases of burning electric cars are discussed. Algorithms are set out to be followed by firefighters and what equipment they will need. A manual for firefighters to deal with a burning electric car in a traffic accident has been prepared.Item ПОДВОДЕН РОБОТ-ПРОЕКТИРАНЕ И КОНСТРУКТИВНИ ОСОБЕНОСТИ(Бургаски свободен университет, 2022) Долчинков, РадостинThe underwater robot descends with a cable from the ship and can capture the seabed with an HD camera, controlled remotely from the board. In fact, it performs almost the same functions as the institute's submarine, but without a crew, which makes it safer and can practically be used indefinitely at great depths. The underwater device is multifunctional. Its main application is to capture the relief of the seabed and determine its geological and geomorphological features, monitoring of seabed habitats, the degree of pollution in the bottom layer, and various types of waste.Item ВЯТЪРНИТЕ ГЕНЕРАТОРИ, КАТО ОБЕКТ НА ОЦЕНКА(Бургаски свободен университет, 2022) Долчинков, РадостинThe peculiarity of wind generators as an object of evaluation is that they are a complex system - equipment that has separate elements that can be subject to selfassessment, as well as the fact that the wind generator that produces electricity together with service equipment can be considered and evaluates as a business, through the approaches and methods used in the valuation of commercial enterprises. The second important feature is that the installed and operated wind generator are permanently connected to the ground through their foundations and are essentially immovable facilities. The necessary documents under the Spatial Development Act are being developed for it and construction and installation activities are being carried out. Therefore, in their assessment as an active object, two appraisal competencies are required - an independent real estate appraiser and an independent appraiser of machinery and equipment. When evaluating a wind generator or wind farm, an independent appraiser of commercial enterprises and receivables may be involved as an independent business.Item ПОЖАРНА БЕЗОПАСНОСТ НА ПЛАВАТЕЛНИ СЪДОВЕ(Бургаски свободен университет, 2022) Долчинков, Радостин; Попов, ИванAccording to the accepted classification, there are seagoing ships and inland waterway vessels. According to their purpose, they are subdivided into small vehicles, passenger ships and hotel ships, cargo ships and container ships and tankers. Depending on the transported cargo, they are for bulk cargo, passenger cargo, self-propelled cargo, mixed, special purpose - scientific, navigation, military. Fire safety requirements vary from vessel to vessel. The publication examines the features and differences of fire safety for seagoing ships and inland waterway vessels.Item ИНЦИДЕНТИ СЪС ЗАПАЛВАЩИ СЕ ЕЛЕКТРИЧЕСКИ АВТОМОБИЛИ ПРИ ПЪТНО ТРАНСПОРТНО ПРОИЗШЕСТВИЕ(Бургаски свободен университет, 2022) Долчинков, Радостин; Сейменлийски, Камен; Попов, ИванThe deviation of cells in the battery is likely to lead to a short circuit in one or more cells, which will generate heat and it is possible to ignite the chemical elements in the cell. The flames from one cell quickly spread to other cells in the battery and this led to an explosion that endangered the lives of passengers. Even if no one is injured by a burning battery of an electric car, the fire releases harmful substances into the air, which are toxic and should not be inhaled without a protective mask with a filter.Item БЕЗОПАСНОСТ НА ЕЛЕКТРИЧЕСКИ АВТОМОБИЛ(Бургаски свободен университет, 2022) Долчинков, Радостин; Сейменлийски, Камен; Попов, ИванThe paper will contain information on the safety of electric cars. The standards for testing the car and its battery and the reaction to impact, cases of burning electric cars after a traffic accident are considered. Before going on sale, electric cars are tested by manufacturers and independent organizations in order to ensure a safe environment for the passenger in the event of an accident. The most important requirements for electric cars are that the battery cannot move from its factory location in the event of an impact and that parts of the battery do not go out of the car or into the passenger compartment.Item ПРЕВАНТИВНИ МЕРКИ И ДЕЙСТВИЯ ПРИ ПОЖАР НА БОРДА НА КОРАБ(Бургаски свободен университет, 2022) Долчинков, Радостин; Попов, ИванFires and accidents during shipyard repairs are often accompanied by the dumping of individual crew members or workers overboard and many casualties. There are many examples in the literature of fires that occurred in ships during repairs. The extinguishing of fires in the ships located in the port of the berth until the arrival of the bodies of the General Directorate for the Prevention of Corruption shall be supervised by the master of the ship. Upon the arrival of the coastal fire services, the fire-fighting management of the captain passed to the senior chief of the General Directorate of Firefighting and he became the head of operational operations. A firefighting headquarters shall be set up and must include the master of the ship or his first assistant and a representative of the ship repair port.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.
