This method uses phase-change emulsion to store heat, which reduces the volume of the hot water storage tank compared with conventional heat pump water heaters, but there are multiple heat exchanges in the system, that is, the heat pump heats the phase-change emulsion through a heat exchanger, and the phase-change emulsion passes through another heat exchanger. The heater heats tap water, which additionally increases the volume of the heat exchange equipment and the heat exchange temperature difference, reducing the heat utilization efficiency

The invention relates to an air source heat pump water heater high-density heat storage integrated machine. The air source heat pump water heater high-density heat storage integrated machine comprisesan outdoor fan (6) and further comprises an evaporator (1), a compressor (3), a condenser / heat reservoir integrated device (4) and a throttling device (5) which are sequentially connected through a refrigerant pipeline (2) and form a circulation loop, wherein the condenser / heat reservoir integrated device (4) has the double functions of a refrigerant condenser and a high-density heat reservoir. Compared with the prior art, the design that the condenser and the heat reservoir are integrated is adopted, the heat exchange temperature difference of stored / released heat of the air source heat pumpwater heater high-density heat storage integrated machine can be decreased by 5-15 DEG C compared with the traditional heat storage and exchange technology, the air source heat pump water heater high-density heat storage integrated machine has the remarkable advantages of being compact in structure, efficient in heat exchange, convenient to install, small in heat exchange temperature difference,and the like, if a compressor is driven by off-peak electricity to store heat for a phase change material, in this way, the operation cost is 1 / 3-1 / 6 of the cost of a traditional direct electric heating mode, and the air source heat pump water heater high-density heat storage integrated machine has good energy saving economical efficiency and can be widely applied to the field of domestic hot water.
Description
technical field [0001] The invention relates to a heat pump water heater, in particular to an air source heat pump water heater high-density heat storage integrated machine. Background technique [0002] In recent years, phase change heat storage technology has attracted widespread attention due to its advantages of high heat storage density and stable heat absorption and release temperature. Phase change energy storage is a technology that uses phase change heat storage materials to absorb or release latent heat of phase change during the phase change process to store and release energy. Phase change energy storage technology has broad application prospects in many fields such as solar thermal utilization, waste heat recovery, power "peak shaving and valley filling", thermal management systems, and building energy conservation. [0003] Air source heat pump water heaters have been widely developed as an energy-saving and environmentally friendly product, and have formed an...
