Summary

Plate heat exchangers as evaporators or condensers in refrigeration systems have many advantages over shell and tube units. The design is compact, turbulence within the plate channels is high giving high heat transfer values and resistance to corrosion and vibration failure is good. Two designs are available, twin-plate and brazed. The former is openable and easily cleaned, the latter can only be chemically cleaned. Twin-plate design can be erected on site, allowing large installations to be made with reduced access. Downflow condensing is normal with good subcooling. Evaporation can be flooded with pump or thermosiphon circulation, or direct expansion. Both evaporator and condenser can be mounted on the same frame for compact assembly. Volumes of refrigerant within the plate channels are very small compared with other heat exchanger types. D.W.H.
