[0016] The following combines the attached drawings to specifically describe the present utility model. As shown in the attached Figure 1 and the attached Figure 2 As shown, an energy-saving system for a circulating air air-conditioning heat pump includes a housing 1. A maintenance door 2 is installed at the upper middle opening of the front part of the housing 1 through a hinge; an exhaust pipe 3 is fixedly connected to the lower middle opening of the front part of the housing 1; an evaporator 4 and a condenser 5 are respectively fixedly connected to the left and right parts inside the housing 1; a first connecting pipe 6 is fixedly connected to the upper end between the evaporator 4 and the condenser 5, and a throttle valve 7 is fixedly connected to the middle position of the first connecting pipe 6; a second connecting pipe 8 is fixedly connected to the lower end between the evaporator 4 and the condenser 5, and a reversing valve 9 is fixedly connected to the middle part of the second connecting pipe 8; a compressor 10 is fixedly connected to the bottom inside the housing 1, and the compressor 10 is connected to the reversing valve 9 through a pipeline; a fan 11 is fixedly connected to the opening at the middle rear side inside the housing 1; a three-way valve 12 is arranged at the upper middle side of the housing 1; one end of a third connecting pipe 13 is fixedly connected to the right end of the three-way valve 12, and the other end of the third connecting pipe 13 penetrates through the right middle side inside the housing 1 and is fixedly connected to the right end of the condenser 5; a thermal insulation layer 14 is wrapped on the outer wall of the third connecting pipe 13, and the thermal insulation layer 14 is located outside the housing 1.

[0017] An energy-saving system for a circulating air air-conditioning heat pump further includes a heat storage type auxiliary heating pipe structure 15, and one end of the heat storage type auxiliary heating pipe structure 15 is fixedly connected to the left end of the three-way valve 12; the other end of the heat storage type auxiliary heating pipe structure 15 penetrates through the left middle side inside the housing 1 and is fixedly connected to the left end of the evaporator 4, which is beneficial to achieving the effect of auxiliary heating of air, can make the air temperature close to the required temperature of the evaporator, and thus can effectively improve the energy-saving effect.

[0018] In this implementation scheme, as shown in the attached Figure 3 As shown, the heat storage type auxiliary heating pipe structure 15 includes a heating cylinder 152. Through holes are respectively opened on the upper and lower sides of the middle part inside the heating cylinder 152, and a fourth connecting pipe 151 is integrally connected inside between the through holes; a heat storage heating block 153 is filled inside the heating cylinder 152; a heat absorption layer 154 is coated on the outer wall of the heating cylinder 152.

[0019] In this embodiment, specifically, one end of the fourth connecting pipe 151 is fixedly connected to the left end of the three-way valve 12 , and the other end passes through the left side inside the shell 1 and is fixedly connected to the left end of the evaporator 4 .

[0020] In this embodiment, specifically, the heating tube 152 is an aluminum alloy tube with a circular cross-section, and the heating tube 152 is located outside the shell 1.

[0021] In this embodiment, specifically, the fourth connecting pipe 151 is made of an aluminum alloy pipe.

[0022] In this embodiment, specifically, the heat storage heating block 153 is a ceramic heat storage block.

[0023] In this embodiment, specifically, the heat absorption layer 154 is made of blue titanium heat absorption coating.

[0024] In this embodiment, specifically, the thermal insulation layer 14 is made of an aluminum silicate thermal insulation cotton layer.

[0025] In this embodiment, specifically, the evaporator 4, condenser 5, reversing valve 9, compressor 10, fan 11 and three-way valve 12 are electrically connected to an external control panel respectively.

[0026] When the heat storage auxiliary heating tube structure 15 is used, the heat absorption layer 154 absorbs the heat of the sunlight and conducts the heat to the heating tube 152. Then the heating tube 152 heats the heat storage heating block 153, and the heat storage heating block 153 stores the heat and heats the fourth connecting tube 151 at the same time. When the air passes through the fourth connecting tube 151, the temperature of the air can be effectively improved, so that the temperature of the air can be closer to the required temperature of the evaporator 4, thereby allowing the evaporator 4 to consume less electrical energy, which can effectively improve the energy-saving effect. Since the heat storage heating block 153 can store heat, when the heat absorption layer 154 can no longer absorb the heat of the sunlight, the heat storage heating block 153 can still heat the fourth connecting tube 151, which can further improve the energy-saving effect. Since the third connecting tube 13 in the utility model is wrapped with the insulation layer 14, the insulation layer 14 can prevent the third connecting tube 13 from being affected by the external environment, thereby preventing the problem of the air temperature rising when the air passes through the third connecting tube 13.
