It has the advantages of compact arrangement, high precision, small size, high heat exchange efficiency, space saving, and high environmental requirements. It is suitable for small refrigeration units. use.</p><p><br></p><p>Under normal circumstances, there is no problem with 15 to 20 years of use, but some air-conditioning system refrigeration hosts can only be used for a few years, and then the plate heat exchanger will be broken down. The main reasons are as follows:</p><p><br></p><p>Quality problems Compared with the heat exchange surface of other heat exchangers, the heat exchange surface of the plate heat exchanger is appropriately thin, that is, 0.5mm, and the allowed corrosion rate is 0.05mm/year. The raw materials of ordinary plate heat exchangers generally use alloy materials (304 or 316). 304 is the cheaper one in stainless steel. It has anti-corrosion ability for some range of materials, but it has weak resistance to hydrochloric acid and sulfuric acid.</p><p><br></p><p>Plate heat exchanger is an important part of heat exchange in process industry equipment. The elastic gasket that seals between the various plate heat sinks is a vulnerable part, and it is also a part that is prone to aging under natural conditions. Its service life has an important influence on the service life of the plate heat exchanger.</p><p><br></p><p>When the gasket of the plate heat exchanger is hardened and no longer has the previous elasticity, or it is not tightened or replaced in time, it will cause the heat exchanger to leak. In addition, the <a href="https://www.empireheatexchanger.com/products.html" rel="noopener noreferrer" target="_blank">plate heat exchanger </a>must be cleaned after long-term operation. It is usually recommended to clean it once every two years.</p>
