High-rise building hot water supply system
 
Due to their high high-rise buildings to use hot water requirement standard, long pipeline system. Mechanical circulating hot water supply system has the following two kinds:
A heating water system, centralized heating partitions
So the appropriate set of mechanical circulating hot water supply system

Concentrated heat partition district hot water pipe network of heating water system become independent system, the volumetric water heater is set at the bottom or the basement. The cold water supply from the district water tank water heater, heating hot water to send note respectively after the use, as shown in figure 3, 18, this can make the cold water, hot water faucet and balance of sanitary ware, this system used more upside down pipe to the layout.
The central heating water rationing system, due to the district heating up keeping all set in one \", so the building design is easy to decorate and arrange. At the same time, convenient maintenance and management, HTM pipeline shortest (i.e., high pressure steam and condensate pipe). But this way of partition of the high-rise building the upper water supply heating equipment (from water device in high rice) long cold water pipes, and thus caused the water points in cold and hot water pressure difference is bigger, and heating and circulating water pump pressure is high, therefore, this way is suitable for high buildings within 100 m.
Second, the partition heating heating water systems
South buildings located respectively in every each of the heating equipment of partition (group 3, 39) or the adjacent area within the scope of heated water along the pipe network system in this area to standby water points, the hot water supply system is called partition heating heating water systems. As district heating equipment in this area, or adjacent areas, and small points cold water, hot water pressure difference; Equipment under pressure also small is advantageous to design, manufacture, installation, save steel, low cost. Defect is HTM pipeline, equipment setup, maintenance and management is not convenient, occupy larger area s applicable to partition the system more (more than three partitions) and building height in port 100 m to L buildings, especially tall building YouYi applies.
High-rise building at the bottom of the laundry, kitchen equipment, such as large water because there are differences between the work system and guest room, should set up a separate water supply, hot water supply system for maintenance and management;
High-rise building hot water supply pipe network hydraulic calculation method, equipment selection, pipe network layout is the same as the low-rise buildings of hot water supply system.
In addition, for the average unit high-rise residential, apartments and a few tall buildings used hot water within the local place, can use local hot water supply systems, such as small gas heater and steam heater, electric heater, solar water heater, etc., to supply a single kitchen, toilet, etc. With hot water. Local hot water supply system is simple, easy maintenance and management, flexible, easy renovation, etc.
