With the serious environmental pollution, the country's requirements for environmental protection have become increasingly strict. Heat pumps are slowly replacing boilers in the leisure and entertainment industry, such as hot spring pools, soaking pools, and constant temperature swimming pools. Chloride ions and free carbon ions in corrosive water are all corrosive. The presence of dissolved oxygen ions greatly enhances the corrosion damage of metal pipelines. How are plate heat exchangers used in the swimming pool industry?
When a heat pump system is used, corrosive stainless steel or titanium plate heat exchangers need to be added to the system for corrosive water sources. Otherwise, if scaling and corrosion of the heat pump system occurs, the cleaning and maintenance of the heat pump system will be greatly enhanced.
Some plate heat exchangers have a high degree of mineralization in the water source, and they are also corrosive to metals.If directly into the system, its corrosive effect will greatly reduce the service life of the unit.If the degree of mineralization is reduced through water treatment, the cost will also be large.Will use the installation of plate heat exchangers in the middle of the heat exchange method to isolate the source water from the unit system, so that the unit system as little as possible contact with the source water to reduce its corrosion.When the mineralization of the source water is 150-500mg / L, a stainless steel plate heat exchanger can be installed.When the source water mineralization is greater than 500mg / L, a titanium alloy plate heat exchanger with corrosion resistance is used.Compared with other types of heat exchange equipment, the plate heat exchanger has a small footprint, small size, high heat exchange efficiency, simple maintenance and low cost.
