Abstract

The subject of the invention is a method of controlling energy in a central heating system or a central hot water system in a building, characterized in that it comprises the following steps: a) initiation by the central unit of taking measurements, wherein for a central heating system, the measurement of temperature and flow is initiated by the heating medium temperature sensors, the outside air temperature sensor and the flow sensors in a continuous mode, while for a central hot water installation, the central unit initiates the measurement of the return temperature and the supply temperature; b) collecting data from the sensors by the data acquisition unit; c) sending data from the sensors to the analysis module, in which the first algorithm for controlling central heating and the central heating installation, for central heating, calculates on the basis of input data: the value of the supply temperature necessary to maintain thermal comfort in the building and the flow, and then calculates the basic relationship between the outside air temperature and the actual demand for thermal power of the building, wherein the input data are data obtained from the temperature and flow sensors and reference data including: calculations of the useful energy and thermal capacity of the building, the actual demand for thermal power of the building, the time needed to cool the building by 1 °C; the demand for thermal power of at least two of the most unfavourably located apartments; whereas for the central central hot water installation, the first algorithm calculates the supply temperature value necessary to maintain the temperature according to the Technical Conditions, and then calculates the basic relationship between the supply and circulation temperatures at the appropriate hours of the day on individual days of the week; d) calculation by the first algorithm of the mixer operation schedule in order to regulate the heating medium in the building installation regardless of the temperatures supplied to the supplier; e) starting the mixer operation in accordance with the schedule calculated in stage d), wherein for central heating installations the mixer operation schedule includes its opening and closing depending on the data supplied from the temperature and flow sensors, where closing the mixer cuts off the heating medium from the heat source, preventing its heating, while for central hot water system the mixer operation schedule includes its opening and closing depending on the data supplied from the return temperature sensors, where closing the mixer cuts off the heating medium from the heat source, preventing its heating, f) controlling the mixer operation in real time, wherein for central hot water system the control is carried out by means of an algorithm that checks the return temperature (i.e. circulation) from the installation in real time and, based on the received data, determines the opening or closing of the mixer, thereby maintaining the desired temperature, while for central heating installations the control is carried out by means of an algorithm that checks the supply temperature, return temperature, heating medium flow, outside air temperature in real time and, based on the received data, determines the opening or closing of the mixer, thereby maintaining the desired temperature and flow.
