Embodiment 1

[0037] like figure 1 As shown, a hot water storage tank of an outer disk type condensing heat exchanger includes an outer shell 1, a heat storage mold box 2, a heat storage material 5, a water tank liner 3, a condensing heat exchanger 4 and a thermal insulation material 6. The heat storage material 5 is filled in the heat storage mold box 2, and the phase change temperature point of the heat storage material 5 is between the inlet and outlet water temperatures; the heat insulation material 6 is foamed between the shell 1 and the water tank liner 3, and the water tank liner 3 There are water inlet and outlet ports 7 and 8; the heat storage mold box 2 is outsourced on the outer wall of the water tank liner 3, and the heat storage mold box 2 and the water tank liner 3 are integrally formed; the condensing heat exchanger 4 is outsourced in the water tank The outer wall of the bile 3; the heat storage mold box 2 is arranged on the upper part of the water tank, and the condensing he...

Embodiment 2

[0041] like figure 2 Shown, the difference between this embodiment and embodiment 1 is:

[0042] The heat storage mold box 2 is arranged at the upper and lower parts of the water tank, and the condensation heat exchanger 4 is arranged at the middle part of the water tank.

[0043] The condensing heat exchanger 4 is formed by connecting two microchannel condensers in parallel, the inlet headers 42 of the two microchannel condensers are communicated through the refrigerant flow pipe 45, and the outlet headers 46 of the two microchannel condensers are connected through The refrigerant circulation pipes 45 are connected. One of the refrigerant circulation pipes is located at the lower part of the outlet header 46 and communicates with the refrigerant outlet pipe 43 . The other refrigerant circulation pipe is located at the upper part of the inlet header 42 and communicates with the refrigerant inlet pipe 44 .

Embodiment 3

[0045] like image 3 Shown, the difference between this embodiment and embodiment 1 is:

[0046] The condensing heat exchanger 4 is a coil heat exchanger with a D-shaped cross section.

Abstract

The invention discloses a combination type heat storage water tank of an external disk heat storage casting box and a condensation heat exchanger. The combination type heat storage water tank comprises a shell, the heat storage casting box, a heat storage material, a water tank liner, the condensation heat exchanger and an insulating material; the heat storage material is filled in the heat storage casting box; the insulating material foams between the shell and the water tank liner; the water tank liner is provided with a water inlet and a water outlet; the outer wall of the water tank liner is externally wrapped by the heat storage casting box; and the outer wall of the water tank liner is externally wrapped by the condensation heat exchanger. According to the invention, the heat storage casting box and the condensation heat exchanger are not directly immersed in water, so as to ensure safety of water quality; and at the same time, the heat storage casting box and the condensation heat exchanger are not corroded, so as to prolong the service lives; and the heat storage casting box and the condensation heat exchanger do not occupy volume of the water tank liner, so as to increase the water storage capacity of the water tank.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a combined heat storage tank used for an outer disk heat storage mold box and a condensing heat exchanger of a heat pump water heater. Background technique [0002] The water tank of a heat pump water heater is usually composed of a water tank liner, an insulation layer and a heating pipe (that is, a condenser). It is a thin-walled copper tube, and most of the thin-walled copper tubes are spirally wound on the outer surface of the water tank liner or installed in the water tank liner after being spirally coiled. The refrigerant flows through the heating tube to condense and release heat, and the water in the water tank absorbs the condensation heat, and the temperature rises. [0003] For a water tank in which the heater is a circular thin-walled copper tube with an outer disk in the form of a single tube, the contact between the copper tube of the thin-walled he...
