Existing energy-saving heating system Problems

Northern region, most of the buildings have heating energy consumption, but also account for a large proportion. At present, many users due to lack of awareness of energy conservation property or excessive emphasis on security features and ignore the work of energy saving heating systems. Respond positively to the call of the national energy saving, so that the building meets energy efficiency standards for residential buildings.
1. Heat
Heat following problems: Improper operation of regulating heat, heat supply and demand imbalance in the system controller, the indoor temperature fluctuations; rely on manual control of combustion, can not be precisely controlled according to the terminal load, boiler start and stop frequently; exhaust gas temperature is high, the heat loss of large; boilers produce condensate, boiler corrosion and shorten the life of the boiler; higher circulating pump power consumption.
2. Network
Pipe network following problems: non-disposable pipe network design is completed, after several transformation system disorder, an annual pre-heating water balance adjustment is not carried out, the presence of water imbalances; existing system off or damaged pipe insulation
Seriously, poor insulation properties; valves and pipe insulation performance is poor, severe heat loss; not be heating, such as school holidays still heating throughout the day according to different needs of end users, without regulating valve.
3. End of the building
Early years of building construction, building maintenance, structural insulation properties are generally not Diego to energy efficiency design standards.
4. Operation and Management
Boiler operation and management of the following problems: managers determine the return water temperature according to the outdoor temperature, usually by kotelshchik boiler return water temperature control start and stop, set the temperature, randomness is strong. The proximal end of the distal portion of the building and the building of high temperature, low temperature, to solve the problem ends, the "big flow, small temperature difference" mode of operation. In addition, the lack of basic metering devices, extensive management.
