Furthermore, the invention also provides an integrated circulating pipeline system, which effectively solves the problem of annual triple supply of air conditioners, floor heating and domestic hot water, improves the utilization efficiency of the heat energy of the air conditioners and avoids energy waste.
In one embodiment, as shown in fig. 3, the integrated circulation pipeline system provided by the invention comprises a first heat exchanger 1, a second heat exchanger 2 and a third heat exchanger. The first heat exchanger 1 comprises a heat source runner 11, a first heated runner 12 and a second heated runner 13, wherein an inlet of the heat source runner 11 is communicated with a high-temperature refrigerant at an outlet of a primary side heat pump compressor; the second heat exchanger 2 comprises an external heat supply flow channel 21 and a third heated flow channel 22, the external heat supply flow channel 21 is connected with the first heated flow channel 12 in series, the second heated flow channel 13 is connected with the third heated flow channel 22 in parallel, and a switching valve group is arranged on the parallel connection pipeline; the third heat exchanger comprises a water storage tank and a heat supply flow passage 32, the heat supply flow passage 32 is communicated with the third heated passage or the second heated passage through the on/off of the switching valve group, and an electronic expansion valve 5 and a compressor 6 are arranged on a pipeline between the third heated passage 22 and the heat supply flow passage 32.
The water storage tank is connected to a water return pipeline of the external heat supply flow channel through a first communication pipeline, the water storage tank is connected to a water supply pipeline of the external heat supply flow channel through a second communication pipeline, a first electromagnetic valve 72 is installed on the first communication pipeline, and a second electromagnetic valve 73 is installed on the second communication pipeline.
In the actual use process, if the hot water of life is heated through the heat pump system of the air conditioner, because the heating power is lower, the instant heating type water outlet of the hot water of life can not be realized, therefore, the third heat exchanger is arranged in the storage water tank of the hot water circulation of life to utilize the circulating water pump to heat the water circulation in the storage water tank, in order to satisfy the water supply demand of the hot water of life. Meanwhile, the floor heating also needs a circulating water pump to circulate the floor heating water so as to realize the function of the floor heating in winter.
In a specific use scenario, the external heat supply flow channel 21 is communicated with a floor heating system pipeline, that is, the external heat supply flow channel 21 is a flow channel for realizing floor heating. When the primary side heat pump system of the air conditioner is in a working state of heat pump heating and floor heating water needs to be provided, the floor heating water enters the second heat exchanger 2 through the external heat supply flow channel 21, the temperature of the water in the first heated flow channel 12 of the first heat exchanger 1 is increased after heat exchange with the heat source flow channel 11, and the water is conveyed to the external heat supply flow channel 21 through a pipeline connected in series, so that heat supply of the floor heating system is realized.
The backwater of the floor heating firstly passes through the external heat supply flow channel 21 of the second heat exchanger 2 to exchange heat with the third heated flow channel 22 of the second heat exchanger 2, and the refrigerant passes through the third heated flow channel 22, then is heated by the secondary side heat pump system, and then enters the heat supply flow channel 32 connected in series with the refrigerant, so that the domestic water in the water storage tank is heated. Therefore, the water supply temperature of the floor heating is 40 ℃, the water supply temperature of the domestic hot water is at least 55 ℃, and in the fluid circulation process, the return water temperature of the floor heating is reduced, meanwhile, a heat source for preparing the domestic hot water is provided for the secondary side heat pump, and the heat utilization rate is improved.
In this embodiment, the switching valve group includes a first switching valve 41, a second switching valve 42, a third switching valve 43, and a fourth switching valve 44; when the first switching valve 41 and the fourth switching valve 44 are turned off and the second switching valve 42 and the third switching valve 43 are turned on, the heat supply flow passage 32 communicates with the third heated flow passage 22, and heats the water in the water storage tank by absorbing heat from the external heat supply flow passage 21. When the first switching valve 41 and the fourth switching valve 44 are turned on and the second switching valve 42 and the third switching valve 43 are turned off, the heat supply flow passage 32 communicates with the second heated flow passage 13, and heats the water in the water storage tank by the heat absorbed from the condenser of the primary side heat pump system.
In the above embodiment, the pipeline system provided by the invention uses the return water of floor heating as the heat source of the secondary side heat pump to prepare domestic hot water, on one hand, the return water temperature of the floor heating water is reduced, the heat exchange temperature difference is increased, and the heat exchange efficiency of the first heat exchanger is improved, on the other hand, the return water of floor heating is used as the heat source of the secondary side heat pump, compared with the case of directly using ambient air as the heat source, the pipeline system can greatly improve the heating cycle working condition of the heat pump, and greatly improve the heating coefficient of the domestic hot water. And because the water supply temperature of floor heating is generally lower than the water supply temperature of domestic hot water, the mode of firstly preparing low-temperature hot water and then preparing high-temperature hot water by taking the return water of the low-temperature hot water as a heat source is adopted, and compared with the mode of directly preparing high-temperature domestic hot water and then exchanging heat or mixing water to obtain low-temperature hot water, the heating cycle of the heat pump can be better improved, so that the heating coefficient of the whole machine is improved.
