Plate heat exchangers (PHEs) have been installed in larger heat pump systems and refrigeration systems since the 1980s. Tech-nicians who deal with these systems need to know some specific details of how they work. Part one of this article covered PHE design, on-site assembly and service, leak indication, freezing risk, and resistance from vibration, pressure, and seismic occurrences. This week the article continues its discussions of the plate heat exchanger as vaporizer and condenser.

Physical examination on the heat exchange station is much simpler than that on human beings, the examination items are no more than temperature, flow, pressure, power and several key points, through these simple parameters, 3 important indicators of heat rate, power consumption and pressure drop were examined, so as to find the crux of the problem of “three highs” of the heat exchange station. Let us see the high-end customized health care services that heating stations can enjoy:
