Ahu (air handling unit) and chiller are both components of a building's HVAC system. The AHU is responsible for circulating and conditioning air, while the chiller is responsible for cooling the water that circulates through the building to remove heat. The AHU uses the chilled water from the chiller to help control the temperature and humidity levels in the building.
The substance commonly used in HVAC chiller systems to make it cold is a refrigerant. This refrigerant circulates through the system, absorbing heat from the surrounding air or water and transferring it outside of the building. Common refrigerants used include R-134a, R-410a, and R-22.
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.
A chiller system uses heat to create chilled water by transferring heat from the water to a refrigerant, which then circulates to reject the heat to the outside environment. The chilled water is then used for air conditioning or refrigeration purposes.

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.
the rupture disc is piped off the chiller barrel (evaporator) and will vent the refrigerant outside incase of over pressure of the unit
