Stainless Steel Plate Heat Exchanger In Water Source Heat Pump

  The plate heat exchanger is a kind of high-efficiency heat exchanger made of a series of metal sheets with a certain corrugated shape. Thin The role of stainless steel plate heat exchanger in water source heat pumprectangular channels are formed between various plates, and heat is exchanged through the plates. The stainless steel plate heat exchanger plays a role in the water source heat pump.

  Cl- and free CO2 in corrosive water are corrosive, and the presence of dissolved oxygen increases the corrosion damage to metal pipelines.When a water source heat pump system is applied, a corrosion-resistant stainless steel plate heat exchanger or a titanium plate heat exchanger should be installed in the system for corrosive and high hardness water sources.Some stainless steel plate heat exchangers have a high degree of mineralization of water sources and are highly corrosive to metals. If they enter the unit directly, the service life of the unit will be reduced due to corrosion.If the degree of mineralization is reduced through water treatment, the cost is high.Usually, a plate heat exchanger is used for intermediate heat exchange to isolate the source water from the unit, so that the unit can completely avoid the corrosive effect of the source water.When the mineralization of the source water is less than 350mg / L, the source system can be connected directly without heat exchanger.When the water source water salinity is 350-500mg / L, a stainless steel plate heat exchanger can be installed.When the source water mineralization is> 500mg / L, a titanium alloy plate heat exchanger with strong corrosion resistance should be installed.
