Abstract

This study is the first and so far the only one in Ukraine dedicated to the experience of using mobile thermal energy storage in emergencies, in particular blackouts. The article considers the issue of ensuring energy security. The classification of heat storage system parameters is given. The considered model of an autonomous heating system with a heat storage system. The impact on the thermal energy storage heating system with different designs of heat generators and fuel types is shown. The results of the operation of a combined system consisting of an autonomous heating system of a separate building equipped with an electric boiler and thermal energy storage are presented. Thermal energy storage is used not only as a buffer between the heat generator and the heating system but also as a source of heat. Integrating the thermal energy storage into the building's heating system ensures constant heat supply to the building, 100% coverage of peak dynamic loads, halving the boiler unit capacity and operating costs by 20%. It has been proven that the presence of thermal energy storage allows solving the problem of providing a stable heat supply in the conditions of a power outage. A detailed description of the conducted study of methods and equipment used during field operation and data processing is given. The results of the field tests of the thermal energy storage in winter operation conditions are provided. Features of the use of the controller for monitoring the heating system's operation with thermal energy storage are provided. The results of field tests are given. An analysis of the received data was carried out. Formulated directions for further scientific research, development, and practical recommendations for the use of mobile heat accumulators in the national economy and the state emergency service of Ukraine. Economic criteria and efficiency criteria aimed at reducing operational costs are considered. The obtained research results can be used to predict the operation of heating and cooling systems equipped with thermal energy storage. Keywords: Heating system, security, blackout, thermal energy storage, monitoring.
