Chiller Refrigeration System Ammonia Charging Equipment SolidWorks

SW design design of chiller refrigeration system ammonia charging equipment 3D model Complex analysis, reasonable structure, welcome to download. The chiller refrigeration system ammonia charging equipment opens the valve of the ammonia charging station leading to the high pressure system, opens the liquid outlet valve of the ammonia bottle (about 1/6 turn), and uses the vacuum state of the system to charge ammonia directly to the high pressure system. When the pressure in the system rises to 0.1~0.2MPa (gauge pressure), a comprehensive inspection should be conducted and no abnormalities should be found before continuing ammonia charging. When the pressure reaches about 0.4MPa (gauge pressure), then open the valve leading to the low pressure system at the ammonia filling station and fill the evaporator with ammonia. To speed up the ammonia charging speed, you 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 filled with ammonia 60% to 70%, so that the entire refrigeration system into normal operation, to be used to cool the object temperature drop, showing the amount of ammonia cycle is not enough to charge again.
