This paper establishes the coupled calculation formulas of the economic thickness of the chilled water pipeline insulation layer and the chilled water temperature rise of the air conditioning based on the existing formulas.Taking the DN50 air conditioning chilled water pipeline as an example,under the actual heat transfer coefficient of the insulation layer's outer surface,the insulation layer's economic thickness of the air conditioning chilled water pipeline and the temperature rise of the air conditioning chilled water in the pipelines are calculated,and the influence of the main parameters on the calculation results is analysed.The insulation layer's economic thickness of the air conditioning chilled water pipeline with different pipeline diameters and the temperature rise of the air conditioning chilled water in the 100 m long steel pipeline are also given.
