Forced Air Heating & Cooling heat exchangers

1. The surface heating water to air heat exchangers exposed to contaminated sediments scum, iron oxides and other solids contained in the water network. The intensity and nature of contamination is determined by water quality (hardness, the concentration of impurities) and its temperature.
2. Pollution water to air heat exchangers with high heat transfer coefficient calculation is accompanied by A significant decrease in the thermal efficiency of the device.
3. Chemical rinsing water to air heat exchangers (in particular, contaminated with iron oxides), is a complex technological operation, requires a professional approach to the selection of reagents and technologies pro-rinsing.
4. With a view to reducing pollution water to air heat exchangers corrosion products of iron and other mechanical impurities in the water mains should be applied clarifying filters, inertial-gravity sumps type GIG, and others cleaning devices.
5. To prevent scale formation on heating surfaces water to air heat exchangers, warming up Sete-hand water with a high stiffness, and reduce the corrosion rate of heat networks is recommended applying adopt a reactive (complexones) water chemistry regime of heat networks.
6. An efficient method for diagnosis of contamination of heat exchangers, designed instrumentation and software to create a system for monitoring the degree of contamination with the assessment of residual life of up to washing (cleaning).
7. When designing and selecting water to air heat exchangers necessarily need to take into account the possible contamination of surface heating. The method of selection of water to air heat exchangers in the light pollution.
