A new type of plate heat exchanger for water-refrigerant systems such as chillers has been developed. Plates embossed with pyramid-like structures are stacked up to form the heat exchanger. Measured heat-transfer coefficients (for convective vaporization) of the heat exchanger are about one and a half to two times higher than those of commercial herringbone-type plate heat exchangers. Moreover, its measured heat-transfer coefficients for water convection are generally in the higher range of values for conventional plate heat exchangers. It was found that the developed plate surface reduces the volume of the plate heat exchanger by nearly half, under equivalent heat-transfer rate and water-side pressure drop, compared to conventional plate heat exchangers.
