Manufacturer of urban centralized heating system

Applicable occasions: Intermediate medium used to transfer heat in urban central heating systems, also known as heat medium or heating element. The widely used heating medium in modern thermal processes is water, because water exists in large quantities in nature, has a large heat capacity, and can circulate economically and effectively in the heat exchange process.

Project Introduction

The intermediate medium used to transfer heat in urban central heating systems, also known as heating medium or heating element. The widely used heating medium in modern thermal processes is water, because water exists in large quantities in nature, has a large heat capacity, and can circulate economically and effectively in the heat exchange process.

The hot water heating system is driven by a water pump for circulation, with a water flow rate of about 1-2 meters per second and a conveying radius of over 10 kilometers. The supply and return water temperature is determined based on technical and economic comparisons. When calculating the outdoor temperature for heating in Chinese urban centralized heating systems, the designed supply water temperature is often 130 ° C or 150 ° C, while the return water temperature is 70 ° C., Therefore, even when there are fluctuations in the operation of the heating system, the heating situation remains relatively stable. During the operation of the hot water heating system, there is less medium leakage, and the required amount of makeup water is relatively small. The treatment requirements for the makeup water are also relatively low.
