Before recovering refrigerant from a chiller suspected of having tube leaks, it is essential to conduct a thorough leak inspection to confirm the presence of leaks and assess their severity. Ensure that all safety protocols are followed, including wearing appropriate personal protective equipment (PPE) and ensuring proper ventilation. Additionally, it is advisable to isolate the chiller from the system, and, if possible, to use a recovery machine designed for the specific refrigerant type to manage any potential contaminants. Lastly, consider using a refrigerant identifier to ensure that the recovered refrigerant is properly classified.

Before recovering refrigerant from a chiller suspected of having tube leaks, it’s essential to conduct a thorough leak detection process to identify the exact location and extent of the leaks. Additionally, ensure that all appropriate safety measures are in place, including wearing personal protective equipment (PPE) and ensuring proper ventilation in the work area. It’s also important to isolate the chiller from the system and verify that the refrigerant pressures are at safe levels before initiating the recovery process.
When evacuating refrigerant from a chiller system, circulating water through the chiller helps dissipate the heat generated during the evacuation process. This prevents the chiller components from overheating and ensures efficient and safe evacuation of the refrigerant. It also helps maintain the chiller's operational efficiency.
There is no single answer to this question as the amount of refrigerant in a chiller can vary based on the specific model, operating conditions, and refrigerant type used. It is best to consult the manufacturer's specifications or technical documentation for the exact amount of refrigerant required for the Carrier 19DK 242 ton chiller.
Chiller uses chilled water while vrv uses refrigerant directly
Leak test and repair the chiller.
According to state of the outlet refrigerant from compressor, it's better we use refrigerant temperature.

The amount of refrigerant vapor left in a 350 ton chiller at 0 degrees would depend on the specific system design, operating conditions, and refrigerant type used. A professional HVAC technician would need to assess the system to determine the exact amount of refrigerant vapor remaining.
Water cooled chiller work on principal that water is circulated in condenser for removal of heat from the system and refrigerant gas is thus condensed in condensor.
