Abstract

The invention relates to the technical field of fluid heaters, in particular to a heat pump hot water unit. The heat pump hot water unit comprises a heat storage water tank and a heat pump main engine. A heat insulating layer, a liner and heat exchanging coil pipes are arranged in the heat storage water tank. The heat pump main engine is connected with the heat storage water tank through a circular water pipe. A heat replacing device communicated with the heat storage water tank is further arranged on the heat storage water tank. The liner comprises an upper liner section, a middle liner section and a lower liner section. The middle liner section is of an S-shaped structure. The lower liner section is parallel to the upper liner section in the vertical direction and located on the inner side of the upper liner section. A cylindrical groove is formed in the bottom axis of the lower liner section in a sunken mode. The heat exchanging coil pipes comprise the first heat exchanging coil pipes coiled on the upper liner section, the second heat exchanging coil pipes coiled on the lower liner section and the third heat exchanging coil pipes arranged in the cylindrical groove. The heat pump hot water unit is low in cost, good in energy-saving effect, rapid in temperature rising of the heat pump water tank and high in heat transferring efficiency.

Description

technical field [0001] The invention relates to the technical field of fluid heaters, in particular to a heat pump water heating unit. Background technique [0002] With the development of people's economy, people's requirements for quality of life are getting higher and higher. People's requirements for showering and bathing are getting higher and higher. Gas water heaters, electric water heaters, and solar water heaters are far from meeting people's needs for comfort, energy saving and safety. It can replace boilers with energy-saving and environmentally friendly hot water supply devices that are not limited by resources. Heat pump hot water units are suitable for indoor swimming pools, hotels, villas, hair salons, bathing and foot therapy, factories and farms and other places that require hot water heat sources. [0003] However, there are still certain defects in the current hot water unit: 1, the cost is relatively high, and energy saving is not enough; 2, the temperat...
