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% for reheating the supply air stream in an air conditioning system.
