EAST Dfgzl High-Rise Direct Connected Heating Unit Water Pump

Product Applications

• Heating systems in high - rise buildings that require zoning (new construction).
• Heating systems in high - rise buildings that require zoning (reconstruction).
• Central air - conditioning water systems in high - rise buildings that require zoning.
• Heating systems in multi - story buildings located at the end of the heat network, where the pressure difference between the supply and return water is too small to ensure normal flow.
• Multi - story buildings located at the highest point within the same heat network, where the topographic height difference is too large.

1.Direct - connection Heat - supply Pipeline Network

• Direct - connection pipeline network, utilizing existing pressure for energy - saving;
• Without additional equipment like heat exchangers, water tanks, and make - up water devices, saving land and investment.

2.High - efficiency Water Pumps

• Variable - frequency operation;
• High - efficiency hydraulic model optimized by CFD design.

3.High Integration Degree

• Automatic operation, data collection, analysis, and control via the Internet of Things, maximizing energy - saving and reducing operating costs.

5.Low - resistance Valves

• Full - bore non - slamming low - resistance check valves;
• Full - bore quick - closing butterfly valves.

6.Low - resistance Corrosion - resistant Pipelines

• Cut by laser equipment and welded by robots, with smooth ports, low resistance, and reliable welding quality;
• Made of well - known brand pipes or tubes, with anti - rust treatment like passivation and electrolytic polishing to prevent corrosion.

DFGZL Energy - saving and Cost - reducing
With the continuous increase in high - rise buildings in our country, the heating hot - water pressure from municipal and heat - exchange stations often fails to meet the demand. Traditional heating units have complex systems, numerous equipment, high maintenance costs, large initial investments, and occupy a lot of space. In some cases, heat loss during heat exchange occurs, and the heating standards for buildings may not be met. Increasing the heat - exchange area or raising the network pressure would significantly increase investment, but our DFGZL high - rise direct - connection heating unit offers a solution.
This unit combines the high - zone heating system and low - zone heating system in high - rise buildings directly. It overcomes many technical drawbacks of traditional high - rise building heating equipment. Without dedicated high - zone boilers, water tanks, and it directly pressurizes the heat - supply water from coal - fired sources to the high zone, avoiding a large amount of heat loss in the heat - exchanger system. It features a simple structure, low equipment investment, high heat efficiency, and fully automatic operation. This heating system is widely applied in high - rise building heating.

Working Environment

• Power supply: 380V×(100±5)%, three - phase five - wire system;
• Ambient temperature: 4°C ~ +40°C (appropriate measures must be taken if beyond this range);
• Relative air humidity: 20% ~ 90% (at 20°C), no condensation;
• Installation site should be free of conductive dust, gases that can corrode metals and damage insulation, and areas with explosion hazards;
• Altitude should not exceed 1000m. When it exceeds, control components should be adjusted accordingly.

Selection of the Unit

Selection of the Pressure - boosting Circulating Pump:

• Head of the Pressure - boosting Pump (m)
  H=Hj−Hw+Hn+Ha
  • Hj: Geometric height from the pump to the top of the system (m)
  • Hw: Resistance loss of the indoor system (m)
  • Hn: Dynamic water - line height of the heat - network supply water at the pump location (m)
  • Ha: Safety margin, can be taken as [a specific value, which is not given in the original content] (m)
• Flow Rate of the Pressure - boosting Pump (m3/h)
  G=kρ(t1−t2)0.86Q
  • k: Additional coefficient, can be taken as 1.1
  • Q: Heat load of the high - zone system (W)
  • t1: Supply water temperature (°C)
  • t2: Return water temperature (°C)
  • ρ: Density of the supply water (kg/m3)
