Title of the articleStudy of hydraulic characteristics of standardized units of apartment heating systems with copper pipes
Abstract.Apartment heating system makes it possible to turn off the flat from the central heating system in a high-rise building. This makes it possible to eliminate the accident or to reconstruct heating system without affecting other users. Such system also allows to use the individual devices for control of heat transfer and measurement of heat consumption for each apartment separately. For apartment heating systems can be used special valves of the reinforcement and the collector node. Thus, in the apartment heating systems may use different piping components of heating appliance with different connection schemes heaters and pipes made of different materials. For hydraulic calculations of this system it is important to know the coefficient of hydraulic resistance of heating appliance and collector nodes. Since local resistance of individual elements is located close to each other, the overall resistance of the node cannot be equal to the sum of the individual elements. It is also unknown how the resistances of the nodes changing at different tuning levels of balancing valves and at different positions of valves control the flow of heat transfer agent. The coefficients of local resistance of heating appliance and collecting nodes of heating system of copper tubes with different tuning levels of balancing valves and at different positions of valve control the flow of heat transfer agent are obtained in KSUAE laboratories and can be used in the calculation of such systems.
Keywords.Reduced coefficient of local resistance, thermostatic valve with bypass, collector nodes and heating appliances of the copper pipes.
