eries Mini Chiller Cooling: in cooling mode, refrigerant is condensed in the aluminum fin-copper tube and evaporated in the plate heat exchanger. Via heat exchange with water in the plate heat exchanger, the temperature of water decreases and it releases heat while the refrigerant absorbs heat and evaporates. With the help of the wired controller, the outflow temperature can meet the user’s requirement.
