ENGINEERING GUIDE YORK YZ Centrifugal Chiller

The majority of chiller components on YZ chillers have been time tested on the tens of thousands of air-cooled and water-cooled YORK® chillers operating globally. The YZ chiller employs the most advanced driveline available - an active magnetic-bearing drive to levitate the driveshaft.

another circuit of water (water-cooled). If the compressor-motor is refrigerant cooled, the chiller also rejects heat generated by motor inefficiency. Air-cooled condensers use fans to facilitate cooling by the ambient air. Water-cooled condensers typically use an evaporative cooling tower. After the water has been chilled, it is distributed ...

3- The compressor is not internally reversible in practice, which increase entropy. However, using a multi-stage compressor with intercooler, or cooling the refrigerant during the compression process, will result in lower entropy, state 2’. 4- In reality, the refrigerant leaves condenser as sub-cooled liquid.
