THE USE OF BATTERIES IN A DOMESTIC HOT

WATER HEAT PUMP DRIVEN BY PV PANELS



1. Objectives of the studya) To analyze the possibility of using batteries in PV supported systems

b) To show the real possibilities of DHW production with a heat pump with PVsupport and batteries.

c) To collect experimental data to calibrate future numerical simulations of DHWproduction systems by heat pumps + photovoltaics + batteries



2. Experimental facilityThe experimental facility was set up on the roof of a Miguel HernándezUniversity building

DHW consumption of a 4 membered family

P=1.5kW

P=470Wp
