[0002] In the field of energy management of modern buildings and industrial facilities, the demand for intelligent control of cooling and heating systems is increasing day by day. In traditional cooling and heating systems, whether it is a system based on air-conditioning compressors for refrigeration or a system relying on boilers or heat pumps for heating, most of them adopt a fixed operation mode, and manual adjustment is required according to seasonal or weather changes. This operation method is not only inefficient, but also difficult to accurately match the actual energy demand, resulting in energy waste and unnecessary operating costs.

These methods usually switch the working mode manually or automatically to adapt to different seasons and weather conditions.

[0047] The fourth water pump 340 is disposed on the cold water outlet pipe 190 of the water supply device, and the fourth water pump 340 is used to discharge the water in the cold water tank 160 through the cold water outlet pipe 190 of the water supply device.

[0048] For the execution principles and interaction processes of the constituent units in the embodiments of this system, reference may be made to the descriptions of the following method embodiments.

[0049] Figure 2 It is a schematic flowchart of a control method for a water supply device provided by an exemplary embodiment of this application. This method can be applied to a water supply device as shown in Figure 1 and includes at least the following steps S11 to S15:

[0050] S11, obtain the ambient temperature;

[0051] Among them, the ambient temperature may be the temperature of the environment where the host 110 is located.

[0052] S12, if the ambient temperature is greater than the preset cooling temperature, control the host 110 to turn on the cooling mode to cool the water in the water supply pipe 130 connected to the host 110;

[0053] The preset cooling temperature is the temperature that triggers the cooling mode of the water supply device, and the preset cooling temperature can be adjusted according to user needs.

[0054] Specifically, in summer, when the ambient temperature is higher than the preset cooling temperature, the water in the water source inlet pipe 170 of the water supply device is generally water that has been heated by natural heat or solar heat. Therefore, the temperature of the water source flowing into the hot water tank 150 and the cold water tank 160 is very high. The temperature of the water source in the hot water tank 150 and the cold water tank 160 is higher than the preset cooling temperature and can reach 40 to 55 °C. This temperature of water is not suitable for direct use by users. Therefore, the method provided in the embodiments of the present application can be used for cooling treatment, and the control host 110 is turned on to the cooling mode to obtain hot water and cold water with appropriate temperatures.

[0055] In some embodiments, when the ambient temperature is higher than the preset cooling temperature and the host 110 is in the cooling mode, the temperature of the water in the water supply pipe 130 can be controlled to be 20 to 25 °C, and this temperature can be adjusted according to user needs.

[0056] S13, control the water in the hot water tank 150 to exchange heat with the water in the water supply pipe 130 that has been cooled in the heat exchanger 140 to cool the water in the hot water tank 150;

[0057] Then, under the condition that the ambient temperature in summer is higher than the preset cooling temperature, after the host 110 is turned on to the cooling mode, the water in the water supply pipe 130 has been cooled. Then, control the water in the hot water tank 150 to exchange heat with the water in the water supply pipe 130 that has been cooled in the heat exchanger 140 to cool the water in the hot water tank 150.

[0058] For example, for the Figure 1 shown water supply device, the first water pump 230 and the second water pump 320 can be turned on so that the high-temperature water in the hot water tank 150 exchanges heat with the water that has been cooled and enters the heat exchanger 140, completing the cooling treatment of the water in the hot water tank 150 to obtain hot water with an appropriate temperature suitable for user use (such as showering). When the user needs to use hot water, the third water pump 330 can be turned on so that the hot water in the hot water tank 150 is discharged through the hot water outlet pipe 180.

[0059] S14, control the water in the water supply pipe 130 that has been cooled to enter the cold water tank 160 to cool the water in the cold water tank 160;

[0060] Similarly, under the condition that the ambient temperature in summer is higher than the preset cooling temperature, after the host 110 is turned on to the cooling mode, the water in the water supply pipe 130 has been cooled. Therefore, the water in the water supply pipe 130 that has been cooled can be controlled to enter the cold water tank 160 to cool the water in the cold water tank 160.

[0061] For example, for the water supply device as Figure 1 shown, the third control valve 290 can be opened and the fourth control valve 310 can be closed, so that the water after temperature reduction treatment in the water supply pipe 130 enters the cold water tank 160, to cool the water in the cold water tank 160 and obtain cold water suitable for users to use (such as for handwashing and domestic water). When the user needs to use cold water, the fourth water pump 340 can be turned on, so that the hot water in the cold water tank 160 is discharged through the cold water outlet pipe 190.

[0062] S15, control the water in the cold water tank 160 to circulate to the return pipe 120 communicating with the main unit 110.

[0063] In some embodiments, if the ambient temperature is greater than the preset temperature reduction temperature, the method may further include the following steps S16 to S17:

[0064] S16, obtain the water temperature of the hot water tank 150 corresponding thereto;

[0065] In some embodiments, a temperature sensor may be used to obtain the water temperature of the hot water tank 150 corresponding thereto.

[0066] For example, for the Figure 1 water supply device shown, a temperature sensor may be provided on the second branch 220 where the first water pump 230 is located, and the temperature measured by this temperature sensor can be used as the water temperature of the hot water tank.

[0067] S17, if the water temperature of the hot water tank is not greater than the preset hot water demand temperature, control the water in the hot water tank 150 not to enter the heat exchanger 140, so as to stop cooling the water in the hot water tank 150.

[0068] Specifically, if the ambient temperature is greater than the preset temperature reduction temperature and the water temperature of the hot water tank is not greater than the preset hot water demand temperature, then at this time the water temperature in the hot water tank 150 is relatively low and already meets the user's demand temperature for hot water. Therefore, the water in the hot water tank 150 can be controlled not to enter the heat exchanger 140, so as to stop cooling the water in the hot water tank 150.

[0069] For example, for the Figure 1 water supply device shown, the first water pump 230 can be turned off to achieve controlling the water in the hot water tank 150 not to enter the heat exchanger 140.

[0070] In some embodiments, the method may further include the following step S18:

[0071] S18, if the water temperature of the hot water tank is greater than the preset hot water demand temperature, control to increase the water flow rate of the water after temperature reduction treatment in the water supply pipe 130 flowing into the heat exchanger 140.

[0072] Specifically, if the ambient temperature is greater than the preset cooling temperature and the water temperature in the hot water tank 150 is greater than the preset hot water demand temperature, it indicates that the water temperature in the hot water tank 150 is relatively high at this time and does not meet the user's hot water demand temperature. Therefore, it is possible to control and increase the water flow rate of the water that has been cooled in the water supply pipe 130 flowing into the heat exchanger 140.

[0073] For example, as Figure 1 shown in the water supply device, it is possible to turn down the first control valve 260 and turn up the second control valve 270 to increase the water flow rate of the water that has been cooled in the water supply pipe 130 flowing into the heat exchanger 140.

[0074] In some embodiments, if the ambient temperature is greater than the preset cooling temperature, the method further includes the following steps S21 to S23:

[0075] S21, obtain the temperature of the cold water tank corresponding to the cold water tank 160;

[0076] In some embodiments, a temperature sensor can be used to obtain the water temperature of the cold water tank corresponding to the cold water tank 160.

[0077] For example, for Figure 1 the water supply device shown, a temperature sensor can be set near the interface on the return water pipe 120 that is close to the connection with the cold water tank 160, and the temperature measured by this temperature sensor can be used as the water temperature of the cold water tank.

[0078] S22, if the temperature of the cold water tank 160 is not greater than the preset cold water supply demand temperature, control the water that has been cooled in the water supply pipe 130 not to enter the cold water tank 160 to stop cooling the water in the cold water tank 160;

[0079] Specifically, if the ambient temperature is greater than the preset cooling temperature and the water temperature of the cold water tank 160 is not greater than the preset hot water demand temperature, it indicates that the water temperature in the cold water tank 160 is relatively low at this time and meets the user's cold water demand temperature. Therefore, it is possible to control the water that has been cooled in the water supply pipe 130 not to enter the cold water tank 160 to stop cooling the water in the cold water tank 160.

[0080] For example, as Figure 1 shown in the water supply device, the third control valve 290 can be closed and the fourth control valve 310 can be opened to control the water that has been cooled in the water supply pipe 130 not to enter the cold water tank 160. At this time, the cold water tank 160 provides a function similar to an expansion tank to absorb the volume change of the water in the water supply device and maintain the pressure balance of the water supply device.

[0081] S23, control the water that has been cooled in the water supply pipe 130 to circulate back to the return water pipe 120.

[0082] When the water after temperature reduction treatment in the water supply pipe 130 does not enter the cold water tank 160, the water after temperature reduction treatment in the water supply pipe 130 is directly circulated back to the water return pipe 120.

[0083] In some embodiments, the method further includes the following steps S24 to S26:

[0084] S24, if the ambient temperature is less than the preset heating temperature, control the main machine 110 to turn on the heating mode to heat the water in the water supply pipe 130, and the preset heating temperature is less than the preset cooling temperature;

[0085] The preset heating temperature is the temperature to trigger the heating mode of the water supply device, and the preset heating temperature can be adjusted according to user needs.

[0086] Specifically, in winter, when the ambient temperature is less than the preset heating temperature, the water in the water source inlet pipe 170 of the water supply device is generally very cold, for example, only about 15 °C. Therefore, the temperature of the water source flowing into the hot water tank 150 and the cold water tank 160 is very low, and the water at this temperature is not suitable for direct use by users. Therefore, the method provided by the embodiments of the present application can be used for heating treatment, and the main machine 110 is controlled to turn on the heating mode to obtain hot water and cold water with appropriate temperatures.

[0087] In some embodiments, when the ambient temperature is less than the preset heating temperature, when the main machine 110 is in the heating mode, the temperature of the water in the water supply pipe 130 can be controlled to be 45 to 50 °C, and this temperature can be adjusted according to user needs.

[0088] S25, control the water in the hot water tank 150 to exchange heat with the water in the water supply pipe 130 after heating treatment in the heat exchanger 140 to heat the water in the hot water tank 150;

[0089] Then, in the working condition where the ambient temperature in winter is less than the preset heating temperature, after the main machine 110 turns on the heating mode, the water in the water supply pipe 130 is heated, and then control the water in the hot water tank 150 to exchange heat with the water in the water supply pipe 130 after heating treatment in the heat exchanger 140 to heat the water in the hot water tank 150.

[0090] For example, for the Figure 1 shown water supply device, the first water pump 230 and the second water pump 320 can be turned on, so that the low-temperature water in the hot water tank 150 exchanges heat with the water after heating treatment entering the heat exchanger 140, completes the heating and cooling treatment of the water in the hot water tank 150, and obtains hot water with an appropriate temperature suitable for user use (such as showering). When the user needs to use hot water, the third water pump 330 can be turned on, so that the hot water in the hot water tank 150 is discharged through the hot water outlet pipe 180.

[0091] S26, control the water in the water supply pipe 130 after temperature increase treatment to enter the cold water tank 160, so as to perform temperature increase treatment on the water in the cold water tank 160.

[0092] Similarly, in the working condition where the ambient temperature in winter is less than the preset heating temperature, after the main unit 110 turns on the heating mode, the water in the water supply pipe 130 has been subjected to temperature increase treatment. Therefore, it is possible to control the water in the water supply pipe 130 after temperature increase treatment to enter the cold water tank 160, so as to perform temperature increase treatment on the water in the cold water tank 160.

[0093] For example, for the Figure 1 shown water supply device, the third control valve 290 can be opened and the fourth control valve 310 can be closed, so that the water in the water supply pipe 130 after temperature decrease treatment enters the cold water tank 160, so as to perform temperature increase treatment on the water in the cold water tank 160, and obtain cold water suitable for users to use (such as for handwashing and domestic water). When the user needs to use cold water, the fourth water pump 340 can be turned on, so that the hot water in the cold water tank 160 is discharged through the cold water outlet pipe 190.

[0094] In some embodiments, if the ambient temperature is less than the preset heating temperature, the method further includes the following steps S27 to S28:

[0095] S27, obtain the water temperature of the hot water tank 150 corresponding thereto;

[0096] S28, if the water temperature of the hot water tank is greater than or equal to the preset hot water demand temperature, control the water in the hot water tank 150 not to enter the heat exchanger 140, so as to stop the temperature increase treatment of the water in the hot water tank 150.

[0097] Specifically, if the ambient temperature is less than the preset heating temperature and the water temperature of the hot water tank is greater than or equal to the preset hot water demand temperature, then at this time, the water temperature in the hot water tank 150 is relatively high and has already met the user's demand temperature for hot water. Therefore, it is possible to control the water in the hot water tank 150 not to enter the heat exchanger 140, so as to stop the temperature increase treatment of the water in the hot water tank 150.

[0098] For example, for the Figure 1 shown water supply device, the first water pump 230 can be turned off to achieve controlling the water in the hot water tank 150 not to enter the heat exchanger 140.

[0099] In some embodiments, if the ambient temperature is less than the preset heating temperature, the method further includes:

[0100] If the water temperature of the hot water tank is less than the preset hot water demand temperature, control to increase the water flow rate of the water in the water supply pipe 130 after temperature increase treatment flowing into the heat exchanger 140.

[0101] Specifically, if the ambient temperature is less than the preset heating temperature and the water temperature in the hot water tank is less than the preset hot water demand temperature, the water temperature in the hot water tank 150 is relatively low at this time and does not meet the user's demand temperature for hot water. Therefore, it is possible to control the increase in the water flow rate of the water that has been heated in the water supply pipe 130 flowing into the heat exchanger 140.

[0102] For example, as Figure 1 shown in the water supply device, the first control valve 260 can be adjusted smaller and the second control valve 270 can be adjusted larger to increase the water flow rate of the water that has been heated in the water supply pipe 130 flowing into the heat exchanger 140.

[0103] In some embodiments, if the ambient temperature is less than the preset heating temperature, the method further includes:

[0104] Obtaining the temperature of the cold water tank 160 corresponding to the cold water tank;

[0105] If the temperature of the cold water tank is not less than the preset cold water supply demand temperature, controlling the water that has been cooled in the water supply pipe 130 not to enter the cold water tank 160 to stop heating the water in the cold water tank 160;

[0106] Controlling the water that has been heated in the water supply pipe 130 to circulate back to the return pipe 120.

[0107] Specifically, if the ambient temperature is less than the preset heating temperature and the water temperature in the cold water tank 160 is not less than the preset cold water demand temperature, it means that the water temperature in the cold water tank 160 is relatively high at this time and meets the user's cold water demand temperature. Therefore, it is possible to control the water that has been heated in the water supply pipe 130 not to enter the cold water tank 160 to stop heating the water in the cold water tank 160.

[0108] For example, as Figure 1 shown in the water supply device, the third control valve 290 can be closed and the fourth control valve 310 can be opened to control the water that has been heated in the water supply pipe 130 not to enter the cold water tank 160. At this time, the cold water tank 160 provides a function similar to an expansion tank to absorb the volume change of the water in the water supply device and maintain the pressure balance of the water supply device.

[0109] In some embodiments, the method further includes:

[0110] Obtaining the water supply temperature corresponding to the main unit 110;

[0111] Obtaining the return water temperature corresponding to the main unit 110;

[0112] If the temperature difference between the water supply temperature and the return water temperature is greater than the preset water supply and return water temperature difference, increasing the working power of the main unit 110.

[0113] The preset supply-return water temperature difference is a threshold value set according to user requirements and system performance, and is used to determine whether the host 110 needs to adjust its working power. When the temperature difference between the supply pipe 130 and the return pipe 120 exceeds this threshold value, it indicates that the current heat exchange efficiency of the water supply device may be insufficient, or the user's requirements have changed (for example, a large amount of hot water or cold water is needed). In order to improve the response speed and heat exchange efficiency of the device, the water supply device will control the host 110 to increase its working power to accelerate the water temperature adjustment speed and meet the user's needs.

[0114] For example, in winter, when the ambient temperature is lower than the preset heating temperature, the water supply device needs to provide hot water for users. If the water temperature in the supply pipe 130 is much lower than the hot water temperature expected by the user, and the water temperature in the return pipe 120 is also relatively low, it indicates that the heating efficiency of the host 110 may be insufficient. At this time, the water supply device will automatically adjust the working power of the host 110 according to the temperature difference between the supply pipe 130 and the return pipe 120 to improve the heating efficiency and ensure that users can obtain sufficient hot water.

[0115] In some embodiments, the working power of the host 110 can be increased by increasing the number of heat pump hosts included in the host 110 or increasing the power of the host 110.

[0116] The present application provides a method of obtaining the ambient temperature; if the ambient temperature is greater than the preset cooling temperature, controlling the host to turn on the cooling mode to cool the water in the supply pipe connected to the host; controlling the water in the hot water tank and the water in the supply pipe after cooling treatment to perform heat exchange in the heat exchanger to cool the water in the hot water tank; controlling the water in the supply pipe after cooling treatment to enter the cold water tank to cool the water in the cold water tank; controlling the water in the cold water tank to circulate to the return pipe connected to the host. The solution can accurately switch the working mode of the water supply device according to different working conditions, streamline the operation process, ensure the safety and reliability of the system operation, and can provide cold water and hot water with appropriate temperatures for users when the ambient temperature is greater than the preset cooling temperature, thereby achieving the technical effect of improving the control efficiency of the water supply system.
