Most of the research on nanofluids focus on the heat/mass transfer or solar collection, while little consideration is given to the synergistic use of the properties of the nanoparticles themselves. Considering that the hybrid nanofluids are the key to realizing the multi-function of various nanoparticle characteristics, in this paper, an experimental system was built to study the combined applications of different nanofluids in the air refinement and heat recovery field. The results showed that the hybrid nanofluids have better long-term stable operating ability, the heat transfer efficiency of 0.01% TiO2-Ag nanofluids is increased by 1.033% compared with deionized water, and the concentrations of total volatile organic compounds and HCHO (formaldehyde) are reduced to 59.1 and 25.3 μg m−3, confirming the excellent heat recovery and air purification performance. Simultaneously, hybrid nanofluids also have good functions of removing PM2.5, PM10, and sterilization. It is expected that this study can guide the multifunctional usage of nanofluids technology in the field of air refinement and heat recovery. [ABSTRACT FROM AUTHOR] |
