Built-Up System / Centrifugal Chiller
Centrifugal Chiller
In a built-up system, a centrifugal chiller moves heat from chilled water to condenser water via the vapor compression cycle. The chilled water is moved to air handling units and other components for comfort cooling or industrial processing. The compressor is the distinguishing component; this type of chiller has a centrifugal compressor that uses a rise and subsequent drop in velocity to compress refrigerant.
Condenser Water Connections: Condenser water connections serve as condenser water supply and return piping.
Chilled Water Connections: Chilled water connections serve as chilled water supply and return piping.
Condenser: The condenser moves heat from refrigerant to condenser water, which causes vapor refrigerant to condense.
Evaporator: The evaporator removes heat from chilled water using refrigerant, which then causes the liquid refrigerant to evaporate.
Controls: Safety and temperature controls properly operate the chiller.
Lubrication Pump: The lubrication pump supplies lubrication oil to the compressor during operation.
Compressor: The compressor circulates refrigerant through the system. It compresses refrigerant gas to create a pressure difference between the evaporator and condenser. This enables the transfer of heat from a cool system (chilled water) to a warmer system (condenser water).
Motor: The motor rotates the compressor.
Condenser Water Connections: Condenser water connections serve as condenser water supply and return piping.
Chilled Water Connections: Chilled water connections serve as chilled water supply and return piping.
