Emulsifying phase-transition heat-storage type heat-pump water heater

Abstract

The invention discloses an emulsifying phase-transition heat-storage type heat-pump water heater. A heat pump structure comprises a compressor, a condenser, a throttle and an evaporator which are communicated in sequence by pipelines to form a sealed structure. The heat pump structure also comprises a heat-storage box body, an emulsion pump and a heat exchanger, wherein the heat-storage box body is internally provided with phase-transition emulsion; the heat exchanger is provided with a running water inlet and a hot water outlet; the condenser is communicated with the heat-storage box body by a pipeline; and the emulsion pump is communicated with the heat-storage box body by a pipeline after passing through the heat exchanger. In the emulsifying phase-transition heat-storage type heat-pump water heater, the needed volume for storing the same heat is reduced, the forming of scale can be obviously reduced, and the metal corrosion can be prevented, so that the occupied area is smaller and the reliability is higher.

Description

technical field [0001] The invention relates to a heat pump water heater, in particular to an emulsified phase change heat storage type heat pump water heater which utilizes an emulsion of a phase change material to store heat. Background technique [0002] At present, the heat pump water heaters on the market are all beneficial to the temperature rise of water to realize heat storage. This heat storage method has the following disadvantages: that is, in order to store more heat, the temperature of heat storage should be increased, or the volume of the water tank should be increased. Large, but increasing the heat storage temperature is contrary to the efficiency of the heat pump, so that the heat pump water heater can only increase the volume of the heat preservation water tank to store enough heat. At the same time, the scaling and corrosion of tap water also damage the heat preservation water tank of the traditional water heater. How to reduce the volume of the thermal in...
