The diagram of the ATS immersion chiller standard refrigeration cycle on this slide shows red dots for where hot high pressure refrigerant gas flows. The solid red lines indicate the chiller’s warm high-pressure refrigerant liquid. Solid blue lines show the chiller’s cold low pressure refrigerant liquid, and the blue dots show where the warm low pressure refrigerant gas is. The heat source connects at the hottest point, next to the compressor outlet.
