Abstract

The invention provides a heat-pump water heater. The heat-pump water heater comprises a water tank, a heat exchange tube assembly and a main pipeline used for circulating refrigerant; wherein the heat exchange tube assembly is arranged inside or outside the water tank and comprises a plurality of heat exchange tube branches; and the main pipeline is connected with the heat exchange tube assembly. The heat-pump water heater has a first heating mode and a second heating mode. In the first heating mode, parts of the heat exchange tube branches in the heat exchange tube assembly are in an opened state. In the second heating mode, the multiple heat exchange tube branches are all in an opened state. According to the technical scheme, the problems that a water tank of a heat-pump water heater in the prior art can only be integrally heated and energy consumption is high can be solved.

Description

technical field [0001] The invention relates to the technical field of heat pump systems, in particular to a heat pump water heater. Background technique [0002] In recent years, after gas water heaters, electric water heaters, and solar water heaters, heat pump water heaters have been more and more widely used because of their energy-saving, comfortable and environmentally friendly features. In order to meet the demand for domestic hot water, heat pump water heaters need to be equipped with large-volume (150L-400L) water tanks. [0003] In the prior art, the water tank of the heat pump water heater can only be heated as a whole, and the energy consumption is relatively high. Contents of the invention [0004] The main purpose of the present invention is to provide a heat pump water heater to solve the problem in the prior art that the water tank of the heat pump water heater can only be heated as a whole and has high energy consumption. [0005] In order to achieve the...
