Abstract

The invention discloses a heat pump water heater. The heat pump water heater comprises a water tank, a heat pump unit, a high-temperature water outlet pipeline, a medium-temperature water outlet pipeline, a water supplementing pipeline, a water inlet pipeline, an a heat preservation pipeline. A heat pump water outlet communicates with the water tank, hot water is supplied to the top of the water tank, the high-temperature water outlet pipeline is mounted at the position, close to the upper, of the water tank, the medium-temperature water outlet pipeline is arranged at the position, close to the middle, of the water tank, the water supplementing pipeline is arranged on the position, close to the lower, of the water tank, the water inlet pipeline communicates with a heat pump water inlet, one end of the heat preservation pipeline communicates with the water tank, the other end of the heat preservation pipeline communicates with the heat pump water inlet, when the water level is lower than the low water level, the water supplementing pipeline and the water inlet pipeline both enter water, the heat preservation pipeline is closed, when the water level is higher than the high water level, the water supplementing pipeline and the water inlet pipeline are closed, water in the water tank flows to the heat pump water inlet through the heat preservation pipeline, when the water level isbetween the low water level and the high water level, the water supplementing pipeline is closed, and the water in the water tank flows to the heat pump water inlet through the heat preservation pipeline. Natural layering of water in the water tank is used, high-temperature water is taken from the top of the water tank, the warm water is taken from the middle, the needs of the different water temperatures by a user are met, and the use experience of the heat pump water heater can be improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat pump water heater. Background technique [0002] Heat pump water heater, also known as air source heat pump water heater, absorbs the low-temperature heat in the air, vaporizes it through the fluorine medium, then compresses it through the compressor, pressurizes it to raise the temperature, and then transforms it into water heating through the heat exchanger, and the high-temperature heat energy after compression This is used to heat the water. [0003] In the heat pump industry, the commonly used forms of water tanks are open water tanks and closed water tanks. The difference between the two water tank systems is whether they are pressurized or not. [0004] The entire water tank of the closed water tank needs to be full of liquid and bear the pressure of the water supply pipe network; the open water tank has no pressure, and the hot water fills the water tank ...
