Question 1. What are the requirements for hydraulic pressure testing of refrigerated and cooling water pipelines?

Question 1. What are the requirements for hydraulic pressure testing of refrigerated and cooling water pipelines? Reference:

(1) After the pipeline system has been installed and the visual inspection has passed, a hydraulic test should be carried out according to the design requirements. When there are no requirements in the design, the following regulations should be met:

① Hot and cold water. The test pressure of the cooling water and energy storage (hot and cold) system, when the working pressure is less than or equal to 1.0MPa, should be 1.5 times the working pressure, and the minimum should not be less than 0.6MPa; when the total pressure is greater than 1.0MPa, it should be Working pressure plus 0.5MPa.

② After the pressure at the lowest point of the system rises to the test pressure, the pressure should be stabilized for 10 minutes, and the pressure drop should not be greater than 0.02MPa. Then the system pressure should be reduced to the working pressure. If there is no leakage in the visual inspection, it is qualified.

(2) The condensate water shall be tested through water flow, and it shall be qualified if there is no leakage and smooth drainage.

(3) air conditioning water system pipeline flushing and drainage. When the system continues to run for more than 2 hours and the water quality remains stable, it can be connected to the equipment.
