Embodiment Construction

[0044] see in conjunction Figure 1 to Figure 10 As shown, according to an embodiment of the present application, a heat storage component includes:

[0045] The heat accumulator 9 includes a heat exchanger 901;

[0046] The heat exchanger 901 is provided with a first heat exchange tube and a second heat exchange tube, and a phase change heat storage material 902 is filled between the first heat exchange tube and the second heat exchange tube.

[0047] Combining the phase change heat storage technology with the hot water system, the latent heat of the phase change heat storage material 902 can be used to store heat for supplying hot water or defrosting of the heat pump system. Due to the high heat storage density of the heat storage material, the phase change temperature is relatively stable Therefore, the heat exchanger 901 filled with the phase change heat storage material 902 has the advantages of high energy storage density, small volume, and relatively stable heat releas...

Abstract

The invention provides a heat storage assembly, a heat pump hot water system and a control method of the heat pump hot water system. The heat accumulation assembly comprises a heat accumulator and a heat exchanger. A first heat exchange tube and a second heat exchange tube are arranged in the heat exchanger, and a phase change heat storage material is filled between the first heat exchange tube and the second heat exchange tube. The phase change heat storage technology and a hot water system are combined, latent heat of the phase change heat storage material can be used for storing heat to be supplied to hot water or a heat pump system for defrosting, and due to the fact that the heat storage material is large in heat storage density and stable in phase change temperature, the phase change heat exchanger has the advantages of being large in energy storage density, small in size and stable in heat release temperature.

Description

technical field [0001] The application belongs to the technical field of hot water systems, and in particular relates to a heat storage component, a heat pump hot water system and a control method thereof. Background technique [0002] Air source heat pump water heaters have been widely promoted and applied due to their energy saving, environmental protection, safety and other characteristics. However, because the water storage tank of conventional air source heat pump water heaters uses the sensible heat of water to store heat, the heat storage density is small, resulting in a large volume of the water tank. , restricting its further promotion and use. Contents of the invention [0003] Therefore, the present application provides a heat storage component, a heat pump hot water system and a control method thereof, which can solve the problem in the prior art that the heat storage density is relatively small, resulting in a large volume of the water tank. [0004] In order...
