Operating principle
| Phase changing of PCM ① If cooling compressor and condenser fan are operated for coolant recirculation, coolant in the chiller freezes PCM. ② If the PCM becomes frozen, coolant compressor and condenser fan stop operation. ③ While the coolant circulation is stopped, compressed air is continuously cooled and dehumidified by frozen PCM and the energy can be reduced with no consumption of electricity. ④ With continuously flowing compressed air, PCM starts melting. When PCM is completely melted, freezing compressor and condenser fan start operation and PCM cooling is carried out. |
| Dehumidification of compressed air If high-temperature compressed air moves into dryer, condensate water and foreign substance are removed from front filter / separator. ② Compressed air goes through 1st cooling and moves to chiller following the path in the heat exchanger for cooling PCM and 2nd heat exchange. ③ In this case, condensate water is separated from compressed air and separator at the bottom of heat exchanger and discharged to the outside. ④ Dehumidified air goes through heater and exchanges heat with high-temperature compressed air in the dryer, leading to increase in temperature and decrease in relative humidity, and good quality of dry compressed air is supplied to the outside. |
