The connection between the expansion tank and the hot (cold) water system does not meet the specification requirements

The "Code for Design of Boiler Rooms" (GB 50041-92) stipulates that valves should not be installed on the connecting pipes between the high-level expansion tank and the hot water system. The connecting pipes mentioned here refer to expansion pipes and circulation pipes. This article is also applicable to air conditioning chilled water systems. However, in some air-conditioning chilled water systems, the expansion pipe of the high-level expansion tank is connected to the water collector in the refrigeration machine room and a valve is installed, which is not allowed. Once the operation is wrong, the system security will be endangered.
