Technical Field

Background

The traditional heat pump water heating system is generally provided with a large-volume heat storage water tank so as to meet the water consumption requirement of a user in the water consumption peak period; the fractal phase change energy accumulator can store the same heat with smaller volume to meet the requirement of users; in a circulating heating type heat pump hot water system, the temperature of water in a heat storage water tank rises along with the continuous heating, so that the inlet water temperature of a heat pump unit is higher and higher, and the heating efficiency of the heat pump unit is lower and higher; the phase change heat storage energy of the fractal phase change energy accumulator enables the water inlet temperature of the heat pump unit to be maintained at a constant value, and enables the heating efficiency of the heat pump unit to be maintained at a higher level.

In the traditional phase-change heat storage system, the heat conduction coefficient of the phase-change material is generally low, so that the heat storage and release rate is too slow, and the hot water requirement of a user cannot be met in time; the traditional heat pump hot water heat storage system cannot realize heat storage and release integration of the phase change energy accumulator while heat supply of the heat pump unit cannot be realized under the condition of a single working condition unit.
