Ammonia Filling Equipment For Chiller Refrigeration System – 3D Model SolidWorks

The 3D model analysis of the chiller refrigeration system ammonia charging equipment designed by SW Design is complex and the structure is reasonable. Welcome to download. Chiller refrigeration system ammonia charging equipment Open the valve leading to the high-pressure system at the ammonia charging station, open the liquid outlet valve of the ammonia bottle (about 1/6 turn), and use the vacuum state of the system to directly charge ammonia to the high-pressure system. When the pressure in the system rises to 0.1-0.2MPa (gauge pressure), a comprehensive inspection should be carried out. After no abnormal conditions, continue to charge ammonia. When the pressure reaches about 0.4MPa (gauge pressure), open the valve leading to the low-pressure system at the ammonia charging station to charge ammonia to the evaporator. In order to speed up the ammonia charging speed, the water pump and compressor can be started to continue to charge ammonia from the low-pressure system. Generally, 60% to 70% of the ammonia required by the refrigeration system is charged first, and the entire refrigeration system is put into normal operation. When the temperature of the cold object to be used drops and the ammonia circulation volume is insufficient, it is charged again.
