[0044] Figure 1 FIG. 1 is a schematic diagram of a household technology system according to an embodiment of the present invention. Figure 1 As shown, the household technology system includes a compressor 1, a four-way valve 2, an outdoor heat exchanger 3, a distribution device 4, a capillary heat exchanger 5, a capillary network system 6 and a fresh air unit 7.

[0045] The exhaust port of the compressor 1 is connected to the first port of the four-way valve 2, and the suction port of the compressor 1 is connected to the second port of the four-way valve 2; the first heat exchange port of the outdoor heat exchanger 3 is connected to the third port of the four-way valve 2; the distribution and distribution device 4 includes a first main pipe 41, a second main pipe 42, a first branch loop 43 and a second branch loop 44, the first main pipe 41 is provided with a first main flow port and a plurality of first branch ports, the second main pipe 42 is provided with a second main flow port and a plurality of second branch ports, and the first branch loop 43 and the second branch loop 44 are respectively connected to a first branch at both ends. An outlet and a second branch outlet, a first switch valve 45 is installed on the first branch loop 43, a second switch valve 46 is installed on the second branch loop 44, the first main outlet is connected to the second heat exchange outlet of the outdoor heat exchanger 3, the second main outlet is connected to the fourth port of the four-way valve 2, an expansion valve 8 is connected between the first main pipe 41 and the outdoor heat exchanger 3; the first branch loop 43 passes through the capillary heat exchanger 5; the capillary network system 6 exchanges heat with the capillary heat exchanger 5; a fresh air heat exchanger 71 is arranged in the ventilation duct of the fresh air unit 7, and the second branch loop 44 passes through the fresh air heat exchanger 71.

[0046] When cooling is needed in summer, the first port of the four-way valve 2 is adjusted to be connected with the third port, and the second port is connected with the fourth port. The first switch valve 45, the second switch valve 46 and the compressor 1 are opened. The high-temperature and high-pressure heat exchange medium discharged from the compressor 1 enters the first port of the four-way valve 2 through the pipeline, and is discharged through the third port of the four-way valve 2, enters the outdoor heat exchanger 3 through the pipeline, exchanges heat with the outside in the outdoor heat exchanger 3, becomes a low-temperature and high-pressure heat exchange medium, is discharged from the outdoor heat exchanger 3, flows through the expansion valve 8, becomes a low-temperature and low-pressure heat exchange medium, and then enters the first main pipe 41 of the distribution and distribution device 4 for diversion. Among them, a part of the low-temperature and low-pressure heat exchange medium enters the first branch loop 43 and flows through the capillary heat exchanger 5, and exchanges heat with the capillary network system 6 in the capillary heat exchanger 5. After the heat exchange, the heat exchange medium in the capillary network system 6 dissipates heat and cools down, so that the heat exchange medium in the capillary network system 6 after cooling down exchanges heat with the air in the room, so that the air in the room is cooled down to achieve a cooling effect. At the same time, the heat exchange medium flowing through the capillary heat exchanger 5 absorbs heat in the heat exchange process, and its own temperature rises. The heated heat exchange medium enters the second main pipe 42 along the first branch loop 43. At the same time, another part of the low-temperature and low-pressure heat exchange medium enters the second branch loop 44 and flows through the fresh air heat exchanger 71 in the fresh air unit 7. In the fresh air heat exchanger 71, heat is exchanged with the outdoor wind flow with a higher temperature sucked into the channel of the fresh air unit 7. After the heat exchange, the wind flow with a higher temperature dissipates heat and cools down, so that the cooled wind flow is transported to the indoor room to achieve a cooling effect. At the same time, the heat exchange medium flowing through the fresh air heat exchanger 71 absorbs heat during the heat exchange process, and its own temperature rises. The heated heat exchange medium enters the second main pipe 42 along the second branch loop 44. The high-temperature heat exchange medium after absorbing heat enters the second main pipe 42 from the first branch loop 43 and the second branch loop 44, enters the fourth port of the four-way valve 2 through the pipeline, is discharged through the second port of the four-way valve 2, and flows back to the compressor 1 through the pipeline. This cycle is repeated to achieve a cooling effect for the room in summer.

[0047] When heating is needed in winter, the first port of the four-way valve 2 is adjusted to be connected with the fourth port, the second port is connected with the third port, the first switch valve 45, the second switch valve 46 and the compressor 1 are opened, and the high-temperature and high-pressure heat exchange medium discharged from the compressor 1 enters the first port of the four-way valve 2 through the pipeline, and is discharged through the fourth port of the four-way valve 2, and enters the second main pipe 42 through the pipeline for diversion. Among them, a part of the high-temperature and high-pressure heat exchange medium enters the first branch loop 43, and flows through the capillary heat exchanger 5, and performs heat exchange with the capillary network system 6 in the capillary heat exchanger 5. After the heat exchange, the heat exchange medium in the capillary network system 6 absorbs heat and heats up, so that the heat exchange medium in the capillary network system 6 after the temperature is increased exchanges heat with the air in the room, so that the air in the room is heated up, and the heating effect is achieved. At the same time, the heat exchange medium flowing through the capillary heat exchanger 5 releases heat during the heat exchange process, and its own temperature is reduced. The heat exchange medium after the temperature is reduced enters the first main pipe 41 along the first branch loop 43. At the same time, another part of the high-temperature and high-pressure heat exchange medium enters the second branch loop 44 and flows through the fresh air heat exchanger 71 in the fresh air unit 7, and performs heat exchange with the outdoor wind flow with lower temperature sucked into the channel of the fresh air unit 7 in the fresh air heat exchanger 71. After the heat exchange, the wind flow with lower temperature absorbs heat and heats up, so that the heated wind flow is transported to the indoor room to achieve the heating effect. At the same time, the heat exchange medium flowing through the fresh air heat exchanger 71 releases heat in the heat exchange process, and its own temperature decreases. The cooled heat exchange medium enters the first main pipe 41 along the second branch loop 44. The low-temperature heat exchange medium after heat dissipation entering the first main pipe 41 from the first branch loop 43 and the second branch loop 44 flows through the expansion valve 8 through the pipeline, and flows into the outdoor heat exchanger 3 after the pressure is reduced, and performs heat exchange with the outside in the outdoor heat exchanger 3, absorbs part of the heat, and its own temperature increases to a certain extent, and then enters the third port of the four-way valve 2 through the pipeline, and is discharged through the second port of the four-way valve 2, and flows back to the compressor 1 through the pipeline. This cycle repeats itself to achieve the heating effect for the room in winter.

[0048] By adopting the household technology system of the present invention, through the mutual cooperation of the compressor 1, the four-way valve 2, the outdoor heat exchanger 3 and the distribution distributor 4, a heat exchange medium for heat exchange can be provided for the indoor capillary network system 6 and the fresh air unit 7 at the same time, eliminating the need to provide a heat pump system for the capillary network system 6 and the fresh air unit 7 respectively, reducing the redundant setting of the equipment, saving the required space and reducing the cost.

[0049] In actual use, the compressor 1, outdoor heat exchanger 3, distribution distributor 4, capillary heat exchanger 5 and fresh air unit 7 can be integrated into a housing and placed outdoors as the overall outdoor unit of the household technology system of the present invention. The air supply duct is connected to the air supply port of the fresh air unit 7 to extend the air supply duct to the room. In order to further save space, the fresh air unit 7 and the compressor 1 can be arranged vertically. After such installation, the equipment is highly centralized and the maintenance is centralized. The fresh air unit 7 is arranged outdoors, which reduces the noise caused by the vibration of its motor to the room.

[0050] like Figure 1 As shown, in this embodiment, the upper right corner of the four-way valve 2 is the first port, the upper left corner is the second port, the lower right corner is the third port, and the lower left corner is the fourth port. The first port is the initial inlet, and the second port is the final outlet. The outdoor heat exchanger 3 has the application effects of both an evaporator and a condenser. In summer, a high-temperature heat exchange medium flows through for cooling, and in winter, a low-temperature heat exchange medium flows through for heating. In the fresh air unit 7, the left side is an air inlet for introducing outdoor air flow, and the right side is an air supply port for conveying fresh air. Inside the fresh air unit 7, a filter 73 is also provided before the fresh air heat exchanger 71 to filter impurities in the air flow. After the fresh air heat exchanger 71, a humidifier 74 is also provided to humidify the air flow and convey it to the room. In addition, in winter, the temperature of the heat exchange medium in the fresh air heat exchanger 71 is directly supplied by the compressor 1. The temperature of the heat exchange medium is high, and the airflow introduced into the fresh air unit 7 heats up quickly when passing through the fresh air heat exchanger 71. The airflow with a higher temperature is easy to humidify when passing through the humidifier 74, which can increase the humidification amount. Figure 1 The directions indicated by the different arrows are the directions in which the heat exchange medium flows in summer and winter.

[0051] Optionally, a first temperature sensor 9 is installed on the return water pipe of the capillary network system 6; a first flow valve 47 is installed on the first branch loop 43; the household technology system also includes a controller, the input end of the controller is communicatively connected to the output end of the first temperature sensor 9, and the output end of the controller is communicatively connected to the control end of the first flow valve 47.

[0052] In summer, after the heat exchange medium in the capillary network system 6 exchanges heat with the indoor air, its own temperature rises, and the heated heat exchange medium flows to the capillary heat exchanger 5 through the return water end pipeline, exchanges heat with the low-temperature heat exchange medium in the capillary heat exchanger 5 to cool down, and then is transported to the capillary network system 6 in the room to exchange heat with the indoor air again. The different temperatures of the heat exchange medium in the return water end pipeline indicate different degrees of heat exchange between the capillary network system 6 and the indoor air. Within a certain temperature range, the lower the temperature of the heat exchange medium in the return water end pipeline, the lower the indoor air temperature, and there is no sufficient heat exchange with the heat exchange medium in the capillary network system 6. At this time, the heat exchange medium in the capillary network system 6 does not need to quickly exchange heat with the heat exchange medium in the capillary heat exchanger 5; the higher the temperature, the higher the indoor air temperature, and there is sufficient heat exchange with the heat exchange medium in the capillary network system 6. At this time, the heat exchange medium in the capillary network system 6 needs to fully and quickly exchange heat with the heat exchange medium in the capillary heat exchanger 5 to reach a lower temperature, and then after heat exchange with the indoor air, the room temperature can be lowered faster.

[0053] In winter, the heat exchange medium in the capillary network system 6 exchanges heat with the indoor air, and its own temperature decreases. The cooled heat exchange medium flows to the capillary heat exchanger 5 through the return water end pipeline, exchanges heat with the high-temperature heat exchange medium in the capillary heat exchanger 5 to increase its temperature, and is then transported to the capillary network system 6 in the room to exchange heat with the indoor air again. The different temperatures of the heat exchange medium in the return water end pipeline indicate different degrees of heat exchange between the capillary network system 6 and the indoor air. Within a certain temperature range, the higher the temperature of the heat exchange medium in the return water end pipeline, the higher the indoor air temperature is, and there is no sufficient heat exchange with the heat exchange medium in the capillary network system 6. At this time, the heat exchange medium in the capillary network system 6 does not need to quickly exchange heat with the heat exchange medium in the capillary heat exchanger 5; the lower the temperature, the lower the indoor air temperature is, and there is sufficient heat exchange with the heat exchange medium in the capillary network system 6. At this time, the heat exchange medium in the capillary network system 6 needs to fully and quickly exchange heat with the heat exchange medium in the capillary heat exchanger 5 to reach a higher temperature, and then after heat exchange with the indoor air, the room temperature can be raised faster.

[0054] Therefore, it is necessary to make the heat exchange medium in the capillary network system 6 and the heat exchange medium flowing through the capillary heat exchanger 5 undergo heat exchange processes of different degrees according to the different temperatures in the return water end pipeline in different seasons. Therefore, it is necessary to control the flow of the heat exchange medium flowing through the capillary heat exchanger 5. When rapid heat exchange is required, the opening of the first flow valve 47 is increased, and when rapid heat exchange is not required, the opening of the first flow valve 47 is reduced. The first temperature sensor 9 monitors the first temperature data of the heat exchange medium in the return water end pipeline of the capillary network system 6 in real time, and transmits the first temperature data to the controller in real time. The controller pre-stores the corresponding relationship between the first temperature data and the opening of the first flow valve 47, and then adjusts the opening of the first flow valve 47 according to the received first temperature data and the corresponding relationship, so as to ensure that the indoor temperature can be quickly raised or lowered without causing waste of heat exchange medium. The control logic of the controller adjusting the opening of the first flow valve 47 according to the first temperature data can be realized according to the existing mature algorithm, and its specific working principle is not repeated here.

[0055] Optionally, a second temperature sensor (not shown) is installed at the air supply outlet of the fresh air unit 7; a second flow valve 48 is installed on the second branch loop 44; the input end of the controller is communicatively connected to the output end of the second temperature sensor, and the output end of the controller is communicatively connected to the control end of the second flow valve 48.

[0056] After the outdoor air is introduced into the fresh air unit 7, it is filtered, heat exchanged, humidified, and then transported to the room through the air supply port. Within a certain temperature range, in summer, if the air temperature discharged from the air supply port is higher, in winter, if the air temperature discharged from the air supply port is lower, it indicates that the air introduced into the fresh air unit 7 needs to be more fully and quickly heat exchanged with the heat exchange medium in the fresh air heat exchanger 71; in summer, if the air temperature discharged from the air supply port is lower, in winter, if the air temperature discharged from the air supply port is higher, it indicates that the air introduced into the fresh air unit 7 does not need to be quickly heat exchanged with the heat exchange medium in the fresh air heat exchanger 71.

[0057] The second temperature sensor monitors the second temperature data at the air outlet of the fresh air unit 7 in real time, and transmits the second temperature data to the controller in real time. The controller pre-stores the correspondence between the second temperature data and the opening of the second flow valve 48, and then adjusts the opening of the second flow valve 48 according to the received second temperature data and the correspondence, to ensure that the flow of the heat exchange medium can both perform appropriate heat exchange with the air in the fresh air unit 7, thereby quickly heating or cooling the indoor temperature without causing waste of the heat exchange medium.

[0058] Optionally, a refrigerant reheater 72 is also provided in the ventilation duct of the fresh air unit 7, and the refrigerant reheater 72 is arranged on the side of the fresh air heat exchanger 71 facing the air supply port of the fresh air unit 7; the household technology system also includes a first refrigerant pipe 10 and a second refrigerant pipe 11, and the opposite ends of the first refrigerant pipe 10 are respectively connected to the exhaust port of the compressor 1 and the inlet of the refrigerant reheater 72; the opposite ends of the second refrigerant pipe 11 are respectively connected to the outlet of the refrigerant reheater 72 and one end of the expansion valve 8 connected to the outdoor heat exchanger 3, and a third switch valve 12 is installed on the second refrigerant pipe 11.

[0059] In summer, the air sucked into the fresh air unit 7 passes through the fresh air heat exchanger 71, and the temperature is too low. If it is directly sent into the room, it is easy to cause human discomfort. Therefore, it is necessary to reheat the low-temperature air after heat exchange before sending it into the room. Figure 1 As shown, in summer, the third switch valve 12 is opened, and the high-temperature heat exchange medium discharged from the compressor 1 is transported to the refrigerant reheater 72 through the first refrigerant pipe 10. The super-low temperature air in the fresh air unit 7 that has undergone heat exchange with the fresh air heat exchanger 71 passes through the refrigerant reheater 72, exchanges heat with the high-temperature heat exchange medium, absorbs part of the heat and heats up to a certain extent. The heated air is transported to the room through the air supply port. At the same time, the heat exchange medium that has undergone heat exchange with the super-cooled air in the fresh air heat exchanger 71 is output through the second refrigerant pipe 11 and transported to the first main pipe 41 after passing through the expansion valve 8. In winter, the third switch valve 12 is closed, and no heat exchange medium flows in the first refrigerant pipe 10 and the second refrigerant pipe 11.

[0060] Optionally, a third flow valve 13 is installed on the first refrigerant pipe 10, and a control end of the third flow valve 13 is communicatively connected to an output end of the controller.

[0061] In summer, if the air temperature at the air outlet of the fresh air unit 7 is too high, it may mean that the air in the fresh air unit 7 has undergone excessive heat exchange with the refrigerant reheater 72, resulting in excessive temperature rise. If the temperature is too low, it may mean that the air in the fresh air unit 7 has not undergone sufficient heat exchange with the refrigerant reheater 72. Therefore, it is necessary to adjust the opening of the third flow valve 13 to adjust the flow rate of the heat exchange medium flowing through the refrigerant reheater 72, and then adjust the degree of heat exchange between the air in the fresh air unit 7 and the refrigerant reheater 72. Because the air sucked into the fresh air unit 7 needs to first be cooled down by the fresh air heat exchanger 71 and then heated up by the refrigerant reheater 72, the air temperature at the air outlet of the fresh air unit 7 reflects the sum of these two processes. Therefore, the controller needs to comprehensively adjust the opening of the second flow valve 48 and the third flow valve 13 according to the second temperature data at the air outlet monitored by the second temperature sensor, so that the air sucked into the fresh air unit 7 is appropriately cooled down at the fresh air heat exchanger 71 and appropriately heated up at the refrigerant reheater 72, and finally delivers air at a temperature suitable for the human body.

[0062] Optionally, the capillary network system 6 includes a capillary sub-water collector 61, a heat exchange tube 62 and a plurality of capillary branch networks 63. The capillary sub-water collector 61 includes a water distributor 611 and a water collector 612, the water distributor 611 is provided with a water supply port and a plurality of water outlets, and the water collector 612 is provided with a water return port and a plurality of water inlets; the heat exchange tube 62 passes through the capillary heat exchanger 5, and the opposite ends of the heat exchange tube 62 are respectively connected to the water supply port and the water return port, and the first temperature sensor 9 is installed at one end of the heat exchange tube 62 close to the water return port; the two ends of each capillary branch network 63 are respectively connected to a water outlet and a water inlet, and each capillary branch network 63 is installed with a fourth switch valve 64. With this arrangement, multiple capillary branch networks 63 can be respectively arranged in multiple rooms. After the heat exchange medium in the heat exchange tube 62 exchanges heat with the heat exchange medium in the capillary heat exchanger 5, it enters the multiple capillary branch networks 63 through the capillary sub-collector 61, and heats or cools multiple rooms at the same time.

[0063] like Figure 1 As shown, in this embodiment, the water distributor 611 is located at the top, and the water collector 612 is located at the bottom. There are three capillary branch nets 63, which are respectively arranged in three rooms. After the heat exchange medium in the heat exchange tube 62 exchanges heat with the heat exchange medium in the capillary heat exchanger 5, it flows into the water distributor 611, and after diversion, it enters the capillary branch nets 63 in the three rooms, and then exchanges heat with the air in the room to achieve the effect of cooling or heating the room. The heat exchange medium after heat exchange flows back to the water collector 612, and is further discharged to the heat exchange tube 62, and exchanges heat with the capillary heat exchanger 5 again, and the cycle continues. If one or several rooms do not need heating or cooling, just close the fourth switch valve 64 on the capillary branch net 63 corresponding to the room.

[0064] Optionally, a third temperature sensor 65 and a thermoelectric valve 66 are installed at one end of each capillary branch network 63 close to the water inlet, the output end of the third temperature sensor 65 is communicatively connected to the input end of the controller, and the output end of the controller is communicatively connected to the control end of the thermoelectric valve 66.

[0065] Each capillary branch network 63 is arranged in a different room, and performs independent heat exchange with the air in the respective room. After the heat exchange, the heat exchange medium in the capillary branch network 63 flows back to the water collector 612 through the corresponding water inlet. Within a certain temperature range, in summer, if the temperature of the heat exchange medium at the water inlet is higher, in winter, if the temperature of the heat exchange medium at the water inlet is lower, it indicates that the heat exchange medium in the capillary branch network 63 needs to perform more sufficient and rapid heat exchange with the air in the room; in summer, if the temperature of the heat exchange medium at the water inlet is lower, in winter, if the temperature of the heat exchange medium at the water inlet is higher, it indicates that the heat exchange medium in the capillary branch network 63 does not need to perform rapid heat exchange with the air in the room.

[0066] Each third temperature sensor 65 monitors the third temperature data of the heat exchange medium at the corresponding water inlet of each capillary branch network 63 in real time, and transmits the third temperature data corresponding to each capillary branch network 63 to the controller respectively. The controller pre-stores the correspondence between the third temperature data and the opening of the thermoelectric valve 66. Therefore, the controller adjusts the opening of the thermoelectric valve 66 on the corresponding capillary branch network 63 according to the received third temperature data corresponding to different capillary branch networks 63 and the correspondence, so as to ensure that the flow rate of the heat exchange medium flowing through each capillary branch network 63 can both perform appropriate heat exchange with the air in the corresponding room, thereby quickly heating up or cooling the indoor temperature without causing waste of heat exchange medium.

[0067] Optionally, the household technology system further includes a heating device (not shown), which is used to heat the capillary heat exchanger 5. The capillary heat exchanger 5 is placed outdoors and has a risk of freezing and cracking in winter. A heating device is provided to prevent the capillary heat exchanger 5 from freezing and cracking.

[0068] The heating device can be any structural form that can heat the capillary heat exchanger 5. In this embodiment, an electric heating system is selected, and the electric heating belt is fixed to the outer wall of the capillary heat exchanger 5, and the capillary heat exchanger 5 is heated by electric energy. The electric heating system can be manually started according to the change in air temperature, or an air temperature sensor can be installed outdoors, and the output end of the air temperature sensor is communicatively connected to the input end of the controller, and the output end of the controller is communicatively connected to the control end of the electric heating system. When the air temperature data monitored by the air temperature sensor is lower than the set air temperature, the controller outputs a start signal to the electric heating system, so that the electric heating system starts the heating operation. The electric heating system is a mature prior art, and its specific structure and working principle will not be repeated here. In order to avoid freezing and cracking, an electric heating system can also be set around the pipeline installed outdoors.

[0069] Optionally, the household technology system further includes a third branch loop 49 and an air conditioner 14, the two ends of the third branch loop 49 are respectively connected to a first branch port and a second branch port, and a fifth switch valve 410 is installed on the third branch loop 49; the air conditioner 14 is installed on the third branch loop 49. In addition to providing cooling and heating for the capillary network system 6 and the fresh air unit 7, the distribution and distribution device 4 can also provide a cold source and a heat source for the air conditioner 14. The air conditioner 14 is installed at a desired location indoors, such as a kitchen, and can be used in conjunction with the capillary network system 6 and the fresh air unit 7 for flexible layout.

[0070] In rooms where the capillary network system 6 and the fresh air unit 7 are not convenient to be arranged, such as the kitchen, cooling and heating can be achieved with the aid of the air conditioner 14. The fifth switch valve 410 is opened. In summer, the low-temperature heat exchange medium flowing to the first main pipe 41 flows through the air conditioner 14 through the third branch loop 49, and performs heat exchange with the high-temperature air flowing through the air conditioner 14 to reduce the air temperature, thereby reducing the room temperature. The heat exchange medium after heat exchange flows to the second main pipe 42 through the third branch loop 49; in winter, the high-temperature heat exchange medium flowing to the second main pipe 42 flows through the air conditioner 14 through the third branch loop 49, and performs heat exchange with the low-temperature air flowing through the air conditioner 14 to increase the air temperature, thereby increasing the room temperature. The heat exchange medium after heat exchange flows to the first main pipe 41 through the third branch loop 49. The air conditioner 14 is a mature prior art, and its specific structure and heat exchange process are not described in detail here.

[0071] Optionally, a fourth flow valve 411 is installed on the third branch circuit 49 ; the input end of the controller is communicatively connected to the control end of the air conditioner indoor unit 14 , and the output end of the controller is communicatively connected to the control end of the fourth flow valve 411 .

[0072] The control end of the air conditioner indoor unit 14 can be a thermostat, and the thermostat can input the temperature required by the personnel. The controller receives the input signal of the thermostat and controls the opening of the fourth flow valve 411, thereby adjusting the flow of the heat exchange medium that exchanges heat with the air conditioner indoor unit 14, and then adjusting the indoor temperature.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
