In addition, since the water in the heat exchange coil 152 and the water in the tank are isolated from each other, the dirty water in the water inlet interface 107 can be prevented from flowing into the domestic water in the tank 151, thereby avoiding the pollution of domestic water.

[0040] For details on the external connection of the water outlet interface 108 and the water inlet interface 107, please refer to Figure 2 The water inlet interface 107 can be used as the return water joint of the air temperature regulating device 200. In addition, the water inlet interface can also be used as a tap water joint to connect to tap water, which is not specifically limited. The water outlet interface 108 can output hot water to the air temperature regulating device 200 for heating in the heat pump heating hot water mode and the fuel heating heating hot water mode, and the water outlet interface 108 can output cold water to the air temperature regulating device 200 for cooling in the heat pump cooling water mode.

[0041] Furthermore, the heat pump system 130 includes a fluorine water heat exchanger 131 and a heat pump circulating water pump 132, the water inlet of the water pipe 1311 in the fluorine water heat exchanger 131 is connected to the first pipe port A1 of the first four-way valve, and the water outlet of the water pipe 1311 in the fluorine water heat exchanger 131 is connected to the first pipe port B1 of the second four-way valve; the heat pump circulating water pump 132 is arranged on the pipeline between the first pipe port A1 of the first four-way valve and the first pipe port B1 of the second four-way valve, so that water flows from the first pipe port A1 of the first four-way valve through the fluorine water heat exchanger 131 to the first pipe port B1 of the second four-way valve.

[0042] Specifically, a heat pump circulation water pump 132 is arranged in the pipeline between the first pipe port A1 of the first four-way valve and the first pipe port B1 of the second four-way valve, which can further control the water flow direction and water flow rate of the pipeline, so that the water flows from the first pipe port A1 of the first four-way valve through the fluorine water heat exchanger 131 to the first pipe port B1 of the second four-way valve at a target water flow rate, thereby controlling the heat exchange speed.

[0043] Optionally, the heat pump circulating water pump 132 is arranged on the pipe between the water outlet of the water pipe 1311 in the fluorine water heat exchanger 131 and the first pipe port B1 of the second four-way valve. This embodiment further optimizes the position of the heat pump circulating water pump 132, and can prevent water from flowing from the first pipe port B1 of the second four-way valve to the water outlet of the water pipe 1311.

[0044] Furthermore, the heat pump system 130 also includes a compressor 133, a third four-way valve 134, an expansion valve 135 and a fin heat exchanger 136, the first pipe port C1 of the third four-way valve is connected to the exhaust port of the compressor 133, the second pipe port C2 of the third four-way valve is connected to the first end of the fluorine pipe 1312 in the fluorine water heat exchanger 131, the third pipe port C3 of the third four-way valve is connected to the suction port of the compressor 133, the fourth pipe port C4 of the third four-way valve is connected to the first end of the fin heat exchanger 136, the second end of the fin heat exchanger 136 is connected to the first end of the expansion valve 135, and the second end of the expansion valve 135 is connected to the second end of the fluorine pipe 1312 in the fluorine water heat exchanger 131.

[0045] Specifically, by setting the third four-way valve 134, the heat pump system has two modes, heating and cooling. The high-temperature and high-pressure gas generated by the compressor 133 can flexibly choose to flow from the first pipe port C1 of the third four-way valve to the second pipe port C2 of the third four-way valve to achieve heating; it can also flexibly choose to flow from the first pipe port C1 of the third four-way valve to the fourth pipe port C4 of the third four-way valve to achieve cooling.

[0046] Furthermore, the trigeneration heating device 100 includes a housing 160, the top of which is provided with an air inlet 103 and an air outlet 104, the internal space of the housing between the air inlet 103 and the air outlet 104 forms a receiving chamber 105, the fin heat exchanger 136 is disposed in the receiving chamber 105 and is located between the air inlet 103 and the air outlet 104; the heat pump system 130 further includes a fan 137 disposed in the receiving chamber 105, the exhaust port of the fan 137 faces the air outlet 104. In order to further save energy, the hot air or cold air discharged from the air outlet 104 can be used for indoor heating or cooling.

[0047] Furthermore, the heating system 140 includes a gas water heater 141 and a heating circulation water pump 142. The water inlet of the gas water heater 141 is connected to the second pipe port A2 of the first four-way valve, and the water outlet of the gas water heater is connected to the second pipe port B2 of the second four-way valve; the heating circulation water pump 142 is arranged on a pipeline between the second pipe port A2 of the first four-way valve and the second pipe port B2 of the second four-way valve, so that water flows from the second pipe port A2 of the first four-way valve through the gas water heater 141 to the second pipe port B2 of the second four-way valve.

[0048] Specifically, a heat circulation water pump 142 is provided in the pipeline between the second pipe port A2 of the first four-way valve and the second pipe port B2 of the second four-way valve, which can further control the water flow direction and water flow rate of the pipeline, so that the water flows from the second pipe port A2 of the first four-way valve through the fluorine water heat exchanger 131 to the second pipe port B2 of the second four-way valve at a target water flow rate, thereby controlling the heat exchange speed.

[0049] Optionally, the heat circulation water pump 142 is arranged on the pipeline between the water outlet of the gas water heater 141 and the second pipe port B2 of the second four-way valve. This embodiment further optimizes the position of the heat circulation water pump 142, and can prevent water from flowing from the second pipe port B2 of the second four-way valve to the water outlet of the gas water heater 141.

[0051] Specifically, the exhaust gas of the gas water heater 141 is medium-high temperature gas. If the heat pump system is in cooling mode, the fin heat exchanger 136 inhales gas from the air inlet 103 to cool the high-temperature gas in the pipe of the fin heat exchanger 136. To avoid affecting the cooling of the fin heat exchanger 136, the exhaust port 106 of the gas water heater 141 is arranged in a direction away from the area where the air inlet 103 and the air outlet 104 are located.

[0052] Furthermore, in order to save space utilization of the trigeneration heating equipment 100 , the water tank 150 is disposed at the bottom of the trigeneration heating equipment, and the heat pump system 130 and the heating system 140 are disposed at the top of the trigeneration heating equipment 100 .

[0053] Furthermore, the heat exchange coil 152 is located inside the box 151. Since high-temperature water flows inside the heat exchange coil 152, the domestic water inside the box 151 is heat-transferred through the heat exchange coil 152, and the heat exchange coil 152 inside the box 151 has a better heat transfer effect than being set outside.
