Ammonia Charging Equipment For Chiller Refrigeration System

SW designed chiller refrigeration system ammonia filling equipment 3D model analysis is complex, the structure is reasonable, and downloading is welcome. Chiller refrigeration system ammonia filling equipment opens the valve from the ammonia filling station to the high-pressure system, and opens the liquid outlet valve of the ammonia bottle (about 1/6 turn), using the vacuum state of the system to directly charge ammonia to the high-pressure system. When the pressure inside the system rises to 0.1～0.2MPa (gauge pressure), a comprehensive inspection should be conducted, and if no abnormalities are found, continue filling ammonia. When the pressure reaches about 0.4MPa (gauge pressure), open the valve from the ammonia filling station to the low-pressure system and fill the evaporator with ammonia. To accelerate the ammonia filling speed, you can start the water pump and compressor, and continue filling ammonia from the low-pressure system. Generally, fill to 60%～70% of the required ammonia amount for the refrigeration system, allowing the entire refrigeration system to operate normally, and when the temperature of the objects being cooled drops and the ammonia circulation appears insufficient, refill.
