The thermal power station in the heating system refers to: the connection place between the heating network and the heat user. Urban centralized heating system: The thermal power plant transmits heat to the thermal power stations in various areas through the first-level pipeline. The thermal power station is responsible for inspecting, regulating and converting the heat medium transmitted by the heat network, and finally transporting it to each user's home through the secondary pipeline.
Central heating is a way to supply heat to a building or area through a centralized heat source. The central heating system usually consists of three main parts: heat source, heat network and user heat dissipation equipment. Heat sources can be thermal power plants, regional boiler rooms or other types of centralized heating facilities, which are responsible for generating heat energy.
Municipal heating system refers to a large-scale centralized heating system built, maintained and managed by the government or urban management department, which is usually composed of a boiler room, a pipe network, a thermal power station and a user terminal. The purpose is to ensure that urban residents can get a comfortable indoor temperature in winter.
Urban centralized heating is a heating method that the steam and hot water generated by the centralized heat source are supplied to the production and life of a city or part of the area through the pipe network. It consists of three parts: heat source, heat network and heat user.
[Answer]: A, B, C, D Urban centralized heating, also known as regional heating, is a heating method that uses centralized heating heat sources to supply thermal energy to industrial enterprises, civil buildings, etc. in one or more areas of the city. The urban centralized heating system consists of heat source, heating pipe network, user and heat conversion facilities.
Central heating refers to the way in which the steam and hot water generated by the centralized heat source are supplied to a city or part of the area with the heat needed for production, heating and life through the pipe network. Central heating is one of the infrastructures of modern cities and an important facility for urban utilities.
提High heating efficiency: The centralized heating system can centrally manage and regulate heating equipment to provide overall and balanced heating effect, so as to improve heating efficiency. Convenient energy-saving management: The central heating system can monitor and adjust the working status and heat release of heating equipment, and can control energy saving according to needs to reduce energy waste.
Poor controllability. The time and temperature of central heating cannot be controlled by the households themselves. Sometimes the temperature may be too high, and sometimes the temperature may be too low for users to adjust by themselves.
The second biggest advantage of centralized heating is that it achieves the protection of the environment. For centralized heating, only one or a few heat sources in a city or a certain unit can be used by all residents, which has changed the pattern of multiple heat sources and pollution.
_Central heating is also conducive to management and can improve the quality of heating.
System monitoring, monitoring and recording system operation parameters, to realize the viewing of historical operation data. The monitoring content includes Various components of the system: cost management, function, statistical analysis of the operating cost of the heating system. Statistics include energy costs, material costs, maintenance costs, labor costs, management costs, etc.
