Condenser pressure in an absorption chiller refers to the pressure within the condenser unit where the refrigerant vapor is condensed into a liquid. It is influenced by the temperature of the cooling medium (usually water or air) used to remove heat from the refrigerant. Maintaining appropriate condenser pressure is crucial for the efficient operation of the chiller, as it affects the overall performance and capacity of the cooling system. High condenser pressure can reduce efficiency and increase energy consumption, while low pressure can lead to inadequate refrigerant flow.

Leak test and repair the chiller.
when the Liebig condenser was invented
A high efficiency purge unit on a chiller is designed to effectively remove non-condensable gases, such as air and moisture, from the refrigerant circuit. By maintaining a low level of these gases, the purge unit helps optimize the chiller's performance, improve energy efficiency, and prevent potential damage to the system. This process enhances the overall reliability and longevity of the chiller while ensuring it operates at peak efficiency.
To add refrigerant to a centrifugal chiller, first ensure the system is safely shut down and properly isolated. Connect a refrigerant cylinder to the service port using appropriate hoses and gauges. Monitor the pressure and temperature to determine the correct amount of refrigerant needed, and then slowly introduce it into the system while observing for any leaks. Finally, confirm the system is operating within the specified parameters before sealing the service port.
According to state of the outlet refrigerant from compressor, it's better we use refrigerant temperature.

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.
A low pressure chiller works by circulating a refrigerant at low pressure through a system that absorbs heat from a process or space. The refrigerant absorbs heat as it changes from a liquid to a gas in the evaporator coils, removing heat from the system. The gas is then compressed to increase its temperature and pressure before being condensed back into a liquid in the condenser coils, releasing the absorbed heat.

When leak testing a low pressure chiller, it is recommended to use a maximum pressure of around 10 psi. This is a safe pressure that can help detect any leaks without risking damage to the chiller components. Always refer to the manufacturer's guidelines for specific pressure recommendations.
In regards to a water chiller unit, the terms low pressure and high pressure refer to the compressor, which takes low pressure and compresses it into high pressure gas, which is then turned into a liquid to cool the unit.
Vfd is used for maintaing the pressure of whole chiller line.
the rupture disc is piped off the chiller barrel (evaporator) and will vent the refrigerant outside incase of over pressure of the unit
