Abstract

The invention discloses a water tank for a heat-pump water heater, the heat-pump water heater and a use method, and relates to the technical field of water heaters. The water tank for the heat-pump water tank, the heat-pump water heater and the use method are invented to solve the problem that a heat-pump water heater in the prior art is low in energy utilization efficiency. The water tank for the heat-pump water heater comprises a water tank inner container, a water tank heat exchanger, a solenoid valve, a first water temperature sensor and a second water temperature sensor, and the water tank inner container comprises an upper container body part and a lower container body part. The water tank heat exchanger comprises a first heat exchange tube surrounding the outer wall of the upper container body part and a second heat exchange tube surrounding the lower container body part, an inlet of the first heat exchange tube is connected with a first flow path, and an outlet of the first heat exchange tube communicates with an inlet of the second heat exchange tube. The inlet of the second heat exchange tube is further connected with a second flow path, the first flow path and the second flow path both communicate with a first refrigerant opening, and an outlet of the second heat exchange tube communicates with a second refrigerant opening. The solenoid valve is arranged on the second flow path. The first water temperature sensor is arranged on the upper container body part, and the second water temperature sensor is arranged on the lower container body part. The heat-pump water heater is used for absorbing heat from air to produce hot water.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a water tank for a heat pump water heater, a heat pump water heater and a use method. Background technique [0002] At present, water heaters mainly include gas water heaters, electric water heaters, solar water heaters, and air-source heat pump water heaters. Air-source heat pump water heaters are more and more popular with users for their energy-saving and comfortable features. [0003] A heat pump water heater is a device that uses the reverse Carnot principle to transfer heat from a low-temperature object to high-temperature water through a medium (refrigerant). The heat pump device can change the phase of the medium and make it cooler than the low-temperature heat source, thereby spontaneously absorbing the heat of the low-temperature heat source; the medium returned to the compressor is compressed into a high-temperature (higher than high-temperature water) high-press...
