Ammonia Charging Equipment For Chiller Refrigeration Systems SolidWorks 3D Model

SW design design chiller refrigeration system ammonia charging equipment 3D model Analyze complex, reasonable structure, welcome to download. Chiller refrigeration system ammonia charging equipment Open the valve of the ammonia charging station to the high-pressure system, open the liquid outlet valve of the ammonia bottle (about 1/6 turn), and charge ammonia directly to the high-pressure system by utilizing the system’s vacuum state. When the pressure in the system rises to 0.1 ~ 0.2MPa (gauge pressure), a full inspection should be carried out, no abnormalities, and then continue to charge ammonia. When the pressure reaches about 0.4MPa (gauge pressure), and then open the ammonia filling station to the low-pressure system valve, to the evaporator ammonia. In order to speed up the charging speed, can start the pump and compressor, continue to charge ammonia from the low-pressure system. Generally, the first charge to the refrigeration system needs to be charged with 60% to 70% of the amount of ammonia, so that the entire refrigeration system into normal operation, to be used to cool the object temperature drop, showing that the ammonia cycle is insufficient to charge again.
