REFRIGERATION - Plate Heat Exchanger/Plate Heat
Plate Heat Exchanger in Refrigeration. Most commercial refrigeration equipment consists of a compressor and a condenser, outside the cold box, and an evaporator inside. The refrigerant travels in a circuit into and out of the area to be cooled, which is usually within an insulated compartment.Some Problems about Plate Heat Exchanger Used in plate for water to refrigerant heat exchanger equal m15mDec 23, 2016Plate heat exchanger is overlaid by numerous very narrow unit channels, the flow of cold water or refrigerant within each unit is very small, and the plate is very thin, so the heat exchange plate for water to refrigerant heat exchanger equal m15mThe theory behind heat transfer - Alfa Lavalreduced. This means that the plate heat exchanger can remain in service far longer between cleaning intervals. Flexibility the plate heat exchanger consists of a framework containing several heat transfer plates. It can easily be extended to increase capacity. Furthermore, it is easy to open for the purpose of cleaning. (This only appliesrefrigerant to water heat exchangerAug 06, 2009The problem with the plate exchanger is the risk of failure resulting in water/refrigerant contamination. I would always try and avoid the potential and offer an alternative scheme. A very interesting comment, often raised in support of using double-walled heat-exchangers.
