Energy saving in HVAC systems using nanofluid

The present study tries to use the methanol-silver nanofluid filled thermosyphon heat exchanger and compares the effectiveness as well as energy saving with pure methanol. Experimental results show that using methanol-silver nanofluid, leads to energy saving around 8.8–31.5% for cooling and 18–100%...

Zusammenfassung:	The present study tries to use the methanol-silver nanofluid filled thermosyphon heat exchanger and compares the effectiveness as well as energy saving with pure methanol. Experimental results show that using methanol-silver nanofluid, leads to energy saving around 8.8–31.5% for cooling and 18–100% for reheating the supply air stream in an air conditioning system. ► This study tries to use the silver-nanofluid filled thermosyphon heat exchanger. ► Experimental data on the effectiveness and energy saving with nanofluid is presented. ► The effect of temperature and humidity on the effectiveness has been investigated. ► Ag-nanofluid, leads to energy saving 8.8–31.5% for cooling and 18–100% for reheating. ► The nanofluid will enhance the thermal conductivity of thermosyphon heat exchanger.
