A. Physical principles One of the most common energy storage systems is the hot water tank based on the sensible heat of water. A heating device produces hot water outside or inside an
Hot water storage tanks store excess thermal energy during periods of low demand and redistribute it during peak hours. This ensures consistent temperature control, reduces energy consumption, and
Background Heating water is typically the second largest use of energy in a home (after space heating and cooling).1 Despite its resource intensity, the hot water delivery system is seldom
State of the art Hot water energy storage is a mature technology used at large scale in Europe and all over the world. For example, in France one can count for more than 14 million domestic hot water (DHW) tanks running on electricity and about 10 millions on gas.
One of the most common energy storage systems is the hot water tank based on the sensible heat of water. A heating device produces hot water outside or inside an insulated tank where it is stored for a short period of time (a couple of days maximum). The stored energy depends on the hot water temperature and on the tank volume.
The stored energy depends on the hot water temperature and on the tank volume. The tank insulation determines the thermal losses and limits the storage period. As presented in the figure, fuel is used to generate hot water. The use of solar energy and heat pumps (HP) are more and more employed to produce hot water with a high efficiency.
(1) Very small reservoirs of 25 to 70 dm3 can be used for storing hot water for a short period of time (couple of hours). However, for large scale applications, very large storage containers are in-situ installed with capacity as high as 100 m3. These applications do not represent the majority and they are out of the scope of this study. 2.
In this way, water contained in the lower tank region is used as an energy storage element wherein the energy stored in Mode I is utilized by the system in Mode II to maintain a lower pressure ratio. Fig. 12 (a) shows the comparison between the condenser capacity and compressor power as a function of time for the two systems.
The storage heat pump system can reach a higher bulk average water temperature in the upper tank region due to the higher heating capacity in Mode II when compared to the conventional system. Fig. 13 shows the heating performance factor (HPF) as a function of time for the storage heat pump and conventional heat pump systems.
