Main Factors

The main factors of choice of thermal energy source for residential and public buildings in case of central heat supply unability are viewed. The current regulatory documents of the Russian Federation in the matt er of design of decentralized heat supply sources - independent boiling rooms and individual boilers - are analyzed. The comparative analysis of proposed fi ndings is made.

Hot Water Supply

A modified scheme of heat supply of residential buildings with dependent connection to external heating networks is considered, providing reliability of heat supply and the necessary comfort in the premises due to mixing in some of wastewater after hot water supply (DHW) heaters at an outdoor temperature exceeding the break point of the temperature graph. The main equations describing the dependence of the water temperature in the supply line on the outside air temperature are analyzed, and a review of possible ways of regulating the heat supply and preventing "overflows" near the beginning and the end of the heating period is carried out, taking into account the requirements of the current regulatory documents of the Russian Federation. Calculations are made to determine the required proportion in the mixture for water consumption after the heaters of hot water supply in the conditions of the application of the scheme of connection of buildings to the heating network. The analysis of obtained results is given, and conclusions are drawn concerning expediency of application of the considered scheme. It is established that, from the power point of view, mixing of wastewater after heaters of DHW in the calculated quantity will allow to provide reliability of heat supply of the main group of residential buildings and safety of activity of people at high temperatures of outside air. It is shown that, at the same time, that the higher the current outdoor temperature, the greater the share of wastewater in the mixture, with the above dependence close to linear, and its numerical coefficients associated only with the calculated outdoor temperature in the construction area for the cold season. It is noted that the introduction of the proposed scheme is possible with a minimum reconstruction of existing units and structures without significant capital costs, and also gives a system-wide effect in the form of increased electricity generation in thermal power plants on thermal consumption.

Hot Water Supply

The arrangement for heat supply of residential buildings with indirect connection to external heating systems is considered, providing reliability of heat input and required comfort in case of cold snaps after the official end of the heating season or before its beginning by supplying water from the return main of the heating system downstream the hot water supply heat exchangers. The calculations have been made to determine the amount of the main components of heat balance of a residential building on an example of one of standard projects being currently used in the climatic conditions of Moscow, subject to the structural characteristics of the building and its occupancy level. It is established that the actual heat output of the heating system when using the system of chilled water downstream the hot water supply heat exchangers as a heat source enables to main-tain an indoor temperature required for safe living conditions with the average daily outdoor air temperature above +2°C, the heat gain from solar radiation being moderate. It is proven that, tak-ing into account the thermal stability of the enclosing structures, the daily flow rate fluctuations do not significantly affect the stability of the temperature conditions of residential buildings or the comfort of their indoor microclimate at high outdoor air temperatures. It is noted that, in terms of reliability of heat supply of the main group of residential buildings and ensuring the life safety, the proposed arrangement is not inferior to the standard two-stage arrangement of connection of DHW heat exchangers with restriction of the total consumption of delivery water and with the associated regulation of heat supply for DHW, heating and ventilation. It is shown that the use of this arrangement involves virtually no extra costs, provides hydraulic resistance of the heating system and ensures a system-wide effect in the form of higher electricity generation at thermal consumption when using cogeneration.

An elementary arrangement of a heat supply of residential buildings with direct connection to external heating systems is considered, providing reliability of heat supply and comfort required in indoor premises in case of cold snaps after the official closure of the heating season, or before the beginning of the same, by supplying water from the return main of the heating system after the hot water heat exchangers. The basic equations are analyzed relating the heat transfer to the heating system with water temperature in the manifold, the inside air temperature and the characteristics of the heaters, with a review of possible methods of regulating the heat supply near the beginning and the end of the heating period provided taking into account requirements of normative documents of the Russian Federation. Calculations are performed to determine the amount of the main components of the heat balance of a residential building on the example of one of the standard projects used currently in the climatic conditions of Moscow taking into account the constructive structural characteristics of the building and its occupancy level. Analysis of the obtained results and conclusions regarding the appropriateness of the application of this arrangement are provided. It is established that the actual heat output of the heating system when using a chilled water network down-stream the hot water supply heat exchangers as a heat source enables to maintain the safe indoor temperature in the building, with the average daily temperature of outdoor air above +2° C in conditions of moderate amount of heat received with solar radiation. It is shown that the use of this arrangement is virtually not accompanied by additional costs, provides hydraulic resistance of the heating system and gives a system-wide effect in the form of higher electricity generation at thermal consumption when using cogeneration.
