ПРЯМЫЕ И ОТНОСИТЕЛЬНЫЕ ИЗМЕНЕНИЯ ТЕМПЕРАТУРЫ В ЗДАНИИ, А ТАКЖЕ ВНУТРЕННИЕ И ВНЕШНИЕ ФАКТОРЫ, ВЛИЯЮЩИЕ НА ТЕМПЕРАТУРУ В ЗДАНИИ

Аннотация

This article is focused on small and medium capacity local heating boilers, together with excessive fuel consumption, lead to a significant non-ecological state of the environment. Therefore, the increase of large-scale thermal plants (IS) will lead to relief from additional fuel extraction. It is known that the main cost of the amount of heat used for utility, residential and public buildings (heating of buildings, ventilation, air condensation and hot water supply) is the cost of heating buildings. Key words: temperature, heat flow, flux, ventilation, human heat, internal barriers, working zone, height limit, lanterns, slat, pipe, rip, infiltration ТЕХНОЛОГИИ ИЗМЕРЕНИЯ ВНУТРЕННИХ ТЕМПЕРАТУР СОВРЕМЕННЫХ СИСТЕМ ОТОПЛЕНИЯ ПРИ ТЕПЛОСНАБЖЕНИИ Аннотация. Эта статья посвящена котлам местного отопления малой и средней мощности, которые в сочетании с чрезмерным потреблением топлива приводят к значительному неэкологическому состоянию окружающей среды. Таким образом, увеличение числа крупномасштабных тепловых электростанций (ИС) приведет к освобождению от дополнительной добычи топлива. Известно, что основной стоимостью количества тепла, используемого для коммунальных, жилых и общественных зданий (отопление зданий, вентиляция, конденсация воздуха и горячее водоснабжение), является стоимость отопления зданий. Ключевые слова: температура, тепловой поток, флюс, вентиляция, сердце человека, внутренние барьеры, рабочая зона, ограничение по высоте, фонари, планка, труба, разрыв, инфильтрация. The useful heat output of any heating circuit consists of the sum of the heat flow transferred to the heat devices through the heat pipes and the heat lost during the movement in the distance between the pipes. Although the flow of heat consumed in the process of movement in the pipes is not very large, it still constitutes some part of the total useful heat flow. To calculate the useful heat flow, first of all, it is necessary to determine the heat flow from the external walls of the building to the outside air, which keeps the temperature in each room at a certain level. In short, it is necessary to fill the wasted heat flow with the heat supplied to the building with the help of heat devices.1 In addition, the heat flow from the heating equipment is used for heating the air passing through the filtration process, equipment inside the building, etc. It is known that in addition to heating devices, there are other sources of heating in the building. The main sources of heat in the building can be lighting equipment, technological equipment, additional heat emitted from people and the kitchen. Therefore, together with the determination of the absolute amount of heat supplied to each room from the heating devices, all the amounts of heat brought into the building from additional sources and consumed from external 1 Anufriev L.N., Kozheinov I.A., Pozin G.M.

It is known that according to the law of conservation of energy, the flow of heat entering the building and the heat flowing out of the building should be equal to each other. In general, to calculate the heat balance of buildings, heat flows entering the building and spending through external barriers are determined. In order to determine the heat capacity of the heating system, the heat balance is determined using the following formula: Q =ΔQ =Q +Q +Q i to’s h.a t.i there: Q is the heat flux lost through external barriers; to’s Q - heat used to heat the air entering the room; h.a Q - heat flow released as a result of technological and household processes or consumed t.i by the economy; Q is the missing part of the heat. h.a If, as a result of the heat balance calculation, there is a lack of heat, additional heat devices are installed in the building rooms, if there is excess heat, the amount of excess heat is absorbed by means of ventilation. Inside a number of buildings, most of the heat content is from human heat. In such a room (lecture room in higher educational institutions, cinema, theater, circus rooms, etc.), the temperature of the internal air is reduced. This reduced temperature is provided by heating devices, and the increase in air temperature and its return to normal is due to the heat released from the gathered people. Often, the calculated heat capacity of heating equipment in public buildings is equal to the amount of heat consumed. To determine the power of heating systems and to fully calculate all their equipment (the number of boilers and their heat-producing surface, heating equipment, calculated amounts of heat and their transfer to consumers; calculation of heat pipes), the external barrier of buildings The remaining heat flow sh
