Název v původním jazyce

Fouling of plastic fiber heat exchanger

Popis výsledku v původním jazyce

Warm wastewater can be used as a source of heat for heat pumps in buildings such as gyms, swimming pools, and laundries. Unfortunately, heat exchangers installed in a sewage channel are negatively affected by fouling because deposits on the heat exchangesurface create additional resistance to heat transfer and decrease the efficiency of the system. Heat exchangers consisting of polypropylene hollow fibres were prepared and tested to transfer heat from wastewater. Two types of wastewater were studied asfoulant: from a shower and from laundry. It was found that these devices have high thermal performance (with an overall heat transfer coefficient of up to 2020 W/m2 K) and can transfer significant amounts of heat (up to 6.5 kW) while working in clean conditions. Fouling tests showed that fouling strongly depends on the type of wastewater. The experiment with shower wastewater showed that fouling was low because it was associated with the accumulation of a small amount of solid particles
