Description

[0002] With the gradual maturity of heat pump technology, heat pump hot water units, as a highly efficient, energy-saving and environmentally friendly equipment, have been increasingly widely used in recent years. Conventional circulating heat pump hot water units usually use a constant temperature water replenishment mode when heating, that is, heating stops when the water temperature in the water tank reaches the set temperature, and water is replenished when the water level is lower than the lower limit. The energy consumption of the unit is relatively high. In the current dual-tank system, the two water tanks usually share a unit for heating and insulation, and there are too many water valves, resulting in a high failure rate. If a heat pump unit is used alone for insulation, the number of heat pump units and insulation water pumps will increase, the overall cost will increase, and the energy consumption will be higher.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] In order to solve the technical problem of high power consumption of water tank heating by the heat pump unit in the prior art, the present application provides a dual water tank water temperature and water level control method, which can adjust the operating frequency of the heat pump unit according to the actual water demand and water temperature, thereby further reducing power consumption on the basis of meeting the user's water demand.

[0044] Figure 1A flow chart of a dual water tank water temperature and water level control method provided for an embodiment of the present application. This method can be applied to scenarios where water temperature is automatically controlled, such as air source heat pump hot water systems, household water heater systems, and the like. This method can be executed by a controller of a heating system, or by a general electronic device connected to the heating system, such as a host computer, a smart phone, a personal computer, and the like. In addition, the execution subject of this method can be hardware or software. When the above-mentioned execution subject is hardware, the execution subject can be one or more of the above-mentioned electronic devices. For example, a single electronic device can execute this method, or multiple electronic devices can cooperate with each other to execute this method. When the above-mentioned execution subject is software, this method can be implemented as multiple software or software modules, or as a single software or software module. No specific limitation is made here.

[0045] like Figure 1 As shown, the method specifically includes:

[0046] Step 101, determining whether the current water temperature of the heating water tank is less than or equal to a first preset temperature.

[0047] In some embodiments, the electronic device executing the present method may obtain the current water temperature of the heating water tank from a temperature sensor disposed in the heating water tank, and determine whether the current water temperature is less than or equal to a first preset temperature.

[0048] Step 102, if it is less than or equal to the first preset temperature, determine the current water level of the thermal insulation water tank.

[0049] In some embodiments, if the current water temperature of the heating water tank is less than or equal to the first preset temperature, the current water level of the insulated water tank can continue to be obtained from the water level sensor disposed in the insulated water tank.

[0050] Step 103, obtaining the target water level corresponding to the current moment, and determining the operating frequency of the heat pump unit corresponding to the current moment based on the current water level and the target water level.

[0051] In some embodiments, the correspondence between the target water level and the current time can be preset. For example, different target water levels can be set at different times of the day to adapt to changes in water consumption within a day. Then, the current water level and the target water level can be compared, and the operating frequency of the heat pump unit can be determined based on the comparison result. The correspondence between the comparison result and the operating frequency can be preset. For example, if the current water level is greater than or equal to the target water level, it means that the amount of water in the current insulation water tank is sufficient. A lower operating frequency can be set to slowly increase the water temperature in the heating water tank; if the current water level is less than the target water level, it means that the amount of water in the current insulation water tank is insufficient. A higher operating frequency can be set to increase the water temperature in the heating water tank as quickly as possible and replenish water to the insulation water tank.

[0052] Step 104, heating the water in the heating water tank based on the operating frequency.

[0053] In some embodiments, after the operating frequency of the heat pump unit is determined, the water in the heating water tank can be heated according to the operating frequency.

[0054] Step 105, if the water temperature of the heating water tank is greater than the first preset temperature, control the water replenishing device to replenish water from the heating water tank to the insulation water tank.

[0055] In the process of water replenishment, the water level of the thermal insulation water tank can be determined in real time so that the water level of the thermal insulation water tank reaches the set water level.

[0056] The dual water tank water temperature and water level control method provided in the embodiment of the present application determines the current water level of the insulation water tank when the current water temperature of the heating water tank is less than or equal to the first preset temperature, determines the corresponding operating frequency of the heat pump unit at the current moment based on the water level, heats the water in the heating water tank based on the operating frequency, and controls the water replenishment device to replenish water from the heating water tank to the insulation water tank if the water temperature of the heating water tank is greater than the first preset temperature. The embodiment of the present application realizes the independence of the two water tanks, the heating water tank performs water replenishment and heating, the insulation water tank guarantees the user's water demand, and adjusts the operating frequency of the heat pump unit according to the water level of the insulation water tank, realizes the adjustment of the power consumption of the heat pump unit according to the actual water demand and water temperature, and further reduces the power consumption on the basis of meeting the user's water demand.

[0057] In some optional implementations, such as Figure 2 As shown, step 103 includes:

[0058] Step 1031, if the season at the current moment is the first season, determine whether the current water level of the insulated water tank reaches the first target water level corresponding to the current moment.

[0059] The first season may be a season with a higher temperature in a year. For example, in summer, the temperature is high, the water demand temperature is slightly lower, but the bathing frequency is high; in spring and autumn, the temperature is low, the water demand temperature is slightly higher, but the bathing frequency is reduced. The daily water consumption corresponding to the three seasons is not much different. Therefore, the first season of this embodiment may be spring, summer, and autumn.

[0060] Every day in the first season, target water levels corresponding to multiple times can be set to adapt to water consumption at different times of the day.

[0061] Step 1032: If the first target water level is reached, determine the water demand corresponding to the current moment.

[0062] The water demand corresponding to different times can be preset, and the water demand at different times can be different or the same. For example, for a building's heating system, the daily water consumption in spring, summer and autumn is close to 20 tons. Calculated based on the heat pump unit running 14 hours a day, the average water demand per hour is about 1.4 tons. The water demand corresponding to each hour can be set to a fixed 1.4 tons. If this method is executed once every hour, the water demand corresponding to the current moment is 1.4 tons.

[0063] Step 1033, determining the water output of the heat pump unit according to the current temperature.

[0064] Specifically, when the water is not heated, the air temperature and the water temperature have a certain relationship. You can set different water temperatures according to different seasons, or set the relationship between the air temperature and the water temperature to determine the water temperature corresponding to the current air temperature. For example, the air temperature is generally about 2°C higher than the water temperature, so the water temperature corresponding to the current air temperature can be calculated. After obtaining the water temperature, the heating capacity corresponding to the current water temperature can be determined based on the pre-calibrated heating capacity curve. Based on the heating capacity and the specific heat capacity of water, the water output that a single heat pump system can produce when heating water to a certain temperature can be estimated.

[0065] Step 1034, determining the operating frequency of the heat pump units based on the water production, water demand and the number of heat pump units.

[0066] Specifically, the number of heat pump units can be pre-configured. The corresponding relationship between water production, water demand, the number of heat pump units, and the operating frequency can be set through a corresponding relationship table or calculated through a formula. As an example, the operating frequency of a single heat pump unit can be calculated according to the following formula (1):

[0067] F=M1 / M2 / N (1)

[0068] Among them, F is the operating frequency of a single heat pump unit, M1 is the water demand corresponding to the current moment, M2 is the water output of a single heat pump unit, and N is the number of heat pump units.

[0069] For example, if the hourly water demand is 1.4 tons and the water output of a single heat pump unit is 1.12 tons, if three heat pump units are used, then F = 1.4 / 1.12 / 3 = 41%. If two heat pump units are used, then F = 1.4 / 1.12 / 2 = 62.5%. Usually, if the operating frequency is too low, it will affect the energy efficiency of the heat pump unit. Therefore, two heat pump units can be used to make the operating frequency greater than 60%.

[0070] This embodiment determines the operating frequency of the heat pump unit at different times according to the water demand, water production and the number of heat pump units in the first season, thereby adjusting the operating frequency of the heat pump unit in real time according to the temperature characteristics, so that the energy consumption of the heat pump unit for heating the water in the heating water tank is more targeted, and the energy consumed for heating the water tank is more closely matched with the actual water demand, which helps to reduce the overall energy consumption of the heat pump unit.

[0071] In some optional implementations, such as Figure 3 As shown, after step 1031, the method further includes:

[0072] Step 1035: If the current water level of the insulated water tank does not reach the first target water level, determine the first preset operating frequency as the operating frequency corresponding to the current moment.

[0073] The first preset operating frequency is a fixed operating frequency. For example, the maximum operating frequency allowed by the heat pump unit can be set as the first preset operating frequency.

[0074] Step 105 includes:

[0075] Step 1051, if the water temperature of the heating water tank is greater than the first preset temperature, control the water replenishing device to replenish water from the heating water tank to the insulation water tank so that the water level of the insulation water tank reaches the first target water level.

[0076] That is, when it is detected that the water level of the thermal insulation water tank reaches the first target water level, the water replenishment to the thermal insulation water tank is stopped.

[0077] This embodiment operates the heat pump unit at a fixed first preset operating frequency when the water level in the insulated water tank has not reached the first target water level. This allows the water in the heating water tank to be heated as quickly as possible when the water level in the insulated water tank has not reached the expected level, thereby improving the heating efficiency.

[0078] In some optional implementations, step 1031 may be performed as follows:

[0079] If the current time reaches the target time of the day, determine the pre-set water level gear corresponding to the target time; if the current water level of the insulated water tank reaches the water level gear, determine that the current water level of the insulated water tank reaches the first target water level corresponding to the current time.

[0080] Among them, the target time belongs to at least three detection times preset in a day. Among the at least three detection times, the water level levels corresponding to the first detection time and the last detection time arranged in chronological order are smaller than the water level levels corresponding to other detection times.

[0081] As an example, four water level levels from level 1 to level 4 can be set, with level 1 being the lowest and level 4 being the highest. The water level is tested at 5:00, 14:00, 18:00, and 22:00 every day. 5:00 corresponds to level 2, 14:00 corresponds to level 3, 18:00 corresponds to level 4, and 22:00 corresponds to level 2. Since water consumption is generally low in the morning and low after 22:00, lower water levels are set at 5:00 and 22:00. 18:00-22:00 is the peak water consumption, and the highest water level is set.

[0082] At any detection moment, if the current water level is greater than or equal to the corresponding water level gear, the above steps 1032 to 1034 can be continued to be executed to determine the operating frequency of the heat pump unit in real time. Further, if the current water level is less than the corresponding water level gear, it is determined that the first target water level has not been reached, and the heat pump unit is controlled to heat the heating water tank according to the first preset operating frequency.

[0083] This embodiment sets multiple detection moments in a day and sets a corresponding water level at each detection moment, thereby adjusting the operating frequency of the heat pump unit in a targeted manner according to the water consumption at different times of the day in actual water use scenarios, thereby helping to avoid excessive energy loss caused by heating at a fixed operating frequency and saving energy.

[0084] In some optional implementations, such as Figure 4 As shown, step 103 includes:

[0085] Step 1036: If the season to which the current moment belongs is the second season and the water level has not reached the second target water level, determine the second preset operating frequency as the operating frequency corresponding to the current moment.

[0086] The second season is usually a season with lower temperatures, such as winter. The second target water level is a fixed water level, and the second preset operating frequency is a fixed operating frequency, which can be the same as or different from the first preset operating frequency. For example, in winter, due to the lower temperature, the heat in the water tank dissipates faster. Therefore, the second preset operating frequency is the highest operating frequency that the heat pump unit can reach. If the water level of the insulated water tank is less than the second target water level (for example, the 3rd gear water level), and the water level of the insulated water tank has not reached the first preset temperature, the water in the heating water tank can be quickly heated.

[0087] Step 105 includes:

[0088] Step 1052, control the water replenishing device to replenish water from the heating water tank to the thermal insulation water tank, so that the water level of the thermal insulation water tank reaches the third target water level.

[0089] The third target water level may be the same as or different from the second target water level. Generally, the third target water level may be greater than the second target water level. For example, the second target water level is the 3rd gear water level, and the third target water level is the 4th gear water level.

[0090] This embodiment utilizes a heat pump unit to heat the water in the heating water tank at a fixed second preset operating frequency during seasons with lower temperatures when the water level in the insulated water tank has not reached the set water level, thereby adapting to lower temperatures and improving heating efficiency.

[0091] In some optional implementations, Figure 4 Based on the corresponding embodiment, Figure 5 As shown, step 104 includes:

[0092] Step 1041: If the current air temperature is less than or equal to the preset auxiliary heating air temperature threshold, determine the inlet and outlet water temperature difference of the heat pump unit.

[0093] For example, the auxiliary heating temperature threshold is 0° C. The inlet and outlet water temperature difference of the heat pump unit can be measured and calculated by using temperature sensors at the water inlet and outlet of the heat pump unit.

[0094] Step 1042: Determine the heating power of the electric auxiliary heating device based on the temperature difference, and perform electric auxiliary heating on the heat pump unit according to the heating power.

[0095] The electric auxiliary heating device is arranged on the heat pump unit, and is used to electrically assist the heat pump unit in heating through a thermal resistor, etc. At the same time, according to the operating frequency determined in step 103, the heat pump unit is operated for heating.

[0096] This embodiment realizes the use of electric auxiliary heating to electrically assist the heat pump unit when the temperature is relatively low, thereby rapidly increasing the water temperature and improving the heating efficiency.

[0097] In some optional implementations, after step 101, the method further includes:

[0098] If the current water temperature of the heating water tank is less than or equal to the first preset temperature, the water replenishing device is controlled to start the water circulation of the heating water tank, replenish water to the heating water tank, and stop supplying water from the heating water tank to the insulation water tank.

[0099] Among them, the water circulation of the heating water tank is started, that is, the water in the heating water tank flows from the water outlet to the heat pump unit, and the heat pump unit heats the water and then flows back to the heating water tank. At the same time, when the water level in the heating water tank is lower than the set water level lower limit, the external water is transported to the heating water tank for water replenishment. At the same time, the heating water tank stops sending water to the insulation water tank to avoid the mixing of the water in the two water tanks, which will cause the water temperature of the insulation water tank to drop.

[0100] This embodiment heats and circulates the water in the heating water tank separately when the water level in the heating water tank is low, so that the water in the heating water tank is quickly heated up and a sufficient amount of water is maintained, thereby improving the timeliness of the water supply of the insulation water tank.

[0101] In some optional implementations, step 105 may be performed as follows:

[0102] If the current water temperature of the heating water tank is greater than the first preset temperature and less than the second preset temperature, the water replenishing device is controlled to stop the water circulation of the heating water tank and stop replenishing water to the heating water tank, and the water replenishing device is controlled to transport the water in the heating water tank to the insulation water tank.

[0103] For example, if the first preset temperature is 45°C and the second preset temperature is 50°C, if the water temperature in the heating water tank is greater than 45°C and less than 50°C, the water in the heating water tank will no longer flow back to the heating water tank, but will flow to the insulation water tank. Water from the outside will no longer flow into the heating water tank. At this time, the heat pump unit continues to operate, causing the water temperature flowing to the insulation water tank to continue to rise, preventing the water temperature of the insulation water tank from decreasing, until the water level in the insulation water tank reaches the target water level, and the heat pump unit shuts down.

[0104] If the current water temperature of the heating water tank is greater than or equal to the second preset temperature, the heat pump unit is controlled to stop running, and the water in the heating water tank is transported to the insulation water tank.

[0105] For example, if the water temperature in the heating water tank is greater than or equal to 50°C, the heat pump unit will no longer heat the water. At this time, the water in the heating water tank will be transported to the insulation water tank until the water level in the insulation water tank reaches the target water level, and then the water supply to the insulation water tank will be stopped.

[0106] This embodiment monitors the water temperature of the heating water tank, and when the water temperature reaches the required level, shuts off the water circulation of the heating water tank to prevent the addition of low-temperature water to the insulation water tank due to the decrease in the water temperature of the heating water tank, thereby ensuring the stability of the water temperature of the insulation water tank.

[0107] In some optional implementations, the method further includes:

[0108] If the current water temperature of the insulated water tank is lower than the third preset temperature, the water replenishing device and the heat pump unit are controlled to heat the water in the insulated water tank according to the third preset operating frequency until the water temperature of the insulated water tank reaches the fourth preset temperature.

[0109] The third preset temperature is the lower limit of the water temperature of the insulated water tank, and the fourth preset temperature is the upper limit of the water temperature of the insulated water tank. That is, if the water temperature of the insulated water tank is too low, the water replenishment device is controlled to start the water circulation between the insulated water tank and the heat pump unit, so that the water in the insulated water tank flows to the heat pump unit, and flows back to the insulated water tank after being heated by the heat pump unit. The third preset operating frequency can be the same as or different from the first preset operating frequency and the second preset operating frequency. For example, the third preset operating frequency is the maximum operating frequency that the heat pump unit can reach, so that the water temperature in the insulated water tank can rise rapidly.

[0110] This embodiment heats the water in the insulated water tank separately when the water temperature in the insulated water tank is too low, so that the water in the insulated water tank is heated first and hot water is provided to the user in time.

[0111] In some optional implementations, the method further includes:

[0112] If the water level in the insulation water tank is greater than or equal to the preset upper water level limit, or the water level in the heating water tank is less than or equal to the preset lower water level limit, the water replenishment device is controlled to stop the water circulation in the insulation water tank, and start the water circulation in the heating water tank, and control the heat pump unit to operate at a third preset operating frequency.

[0113] For example, the upper limit of the water level of the insulation water tank is level 4, and the lower limit of the water level of the heating water tank is level 1. When the water level of the insulation water tank exceeds level 4, the water volume of the insulation water tank is sufficient, or when the water level of the heating water tank is lower than level 1, the water volume of the heating water tank is insufficient. At this time, the insulation water tank is no longer replenished and heated, and the heating water tank is replenished and heated alone. When the heat pump unit is running, it can operate according to the fixed third preset operating frequency to make the heating

[0114] This embodiment can control the water levels of the two water tanks in time by setting the upper limit of the water level of the insulation water tank and the lower limit of the water level of the heating water tank, thereby avoiding resource waste or water shortage caused by the water level exceeding the normal range.

[0126] Figure 7 A schematic diagram of the structure of a dual water tank water supply system provided in an embodiment of the present application. The system specifically includes: a heating water tank 701, an insulation water tank 702, a controller 703, a heat pump unit 704, a heating temperature sensor 705 (T1), an insulation water level sensor 706 (L1) and a water replenishment device 707.

[0127] The heating temperature sensor 705 is arranged in the heating water tank 701, and is used for collecting the water temperature of the heating water tank 701. The heat preservation water level sensor 706 is arranged in the heat preservation water tank 702, and is used for collecting the water level of the heat preservation water tank 702.

[0128] The water replenishment device 707 is connected to the heating water tank 701, the heat preservation water tank 702 and the heat pump unit 704 through pipelines. The water replenishment device 707 may include a water pump and a valve, which may be controlled by the controller 703 to automatically transport the water in the heating water tank 701 to the heat preservation water tank 702, and control the water circulation of the heating water tank 701 and the heat preservation water tank 702.

[0129] The controller 703 is electrically connected to the water replenishment device 707 , the heat pump unit 704 , the heating temperature sensor 705 , and the insulation water level sensor 706 .

[0130] The controller 703 is used to execute the dual water tank water temperature and water level control method described in any of the above embodiments to heat the heating water tank 701 and control the water replenishment device 707 to replenish water from the heating water tank 701 to the insulation water tank 702.

[0131] The dual water tank water supply system provided in the embodiment of the present application realizes the independence of the two water tanks by setting a heating water tank, an insulated water tank, a controller, a heat pump unit, a heating temperature sensor, an insulated water level sensor and a water replenishment device, and utilizing at least the above-mentioned dual water tank water temperature and water level control method of the controller. The heating water tank performs water replenishment heating, the insulated water tank ensures the user's water demand, and the operating frequency of the heat pump unit is adjusted according to the water level of the insulated water tank, thereby realizing the adjustment of the power consumption of the heat pump unit according to the actual water demand and water temperature, and further reducing the power consumption on the basis of meeting the user's water demand.

[0132] In some optional implementations, such as Figure 8 As shown, the water replenishing device 707 includes a first valve 7071 , a second valve 7072 , a first water pump 7073 , and a second water pump 7074 .

[0133] The water outlet of the heating water tank 701, the first water pump 7073, the heat pump unit 704, the first valve 7071, and the water inlet of the heating water tank 701 are connected in sequence through pipes; the water outlet of the insulation water tank 702, the second water pump 7074, the heat pump unit 704, the second valve 7072, and the water inlet of the insulation water tank 702 are connected in sequence through pipes.

[0134] The controller 703 is electrically connected to the first valve 7071 , the second valve 7072 , the first water pump 7073 , the second water pump 7074 , the heat pump unit 704 , the heating temperature sensor 705 , and the heat preservation water level sensor 706 .

[0135] Specifically, when water needs to be transported from the heating water tank 701 to the insulated water tank 702, the first water pump 7073 can be controlled to be turned on, the second water pump 7074 can be turned off, and the first valve 7071 can be closed and the second valve 7072 can be opened. Driven by the first water pump 7073, the water in the heating water tank 701 flows back to the insulated water tank 702 through the heat pump unit 704 and the second valve 7072.

[0136] When it is necessary to replenish water and heat the heating water tank 701 separately, the first water pump 7073 can be controlled to be turned on, the second water pump 7074 can be turned off, and the first valve 7071 can be opened and the second valve 7072 can be closed. Driven by the first water pump 7073, the water in the heating water tank 701 flows back to the heating water tank 701 through the heat pump unit 704 and the first valve 7071.

[0137] When it is necessary to heat the insulated water tank 702 separately, the first water pump 7073 can be controlled to be closed, the second water pump 7074 can be turned on, and the first valve 7071 can be closed and the second valve 7072 can be opened. Driven by the second water pump 7074, the water in the insulated water tank 702 flows back to the heating water tank 701 through the heat pump unit 704 and the second valve 7072.

[0138] This embodiment achieves flexible control of the water circulation of the heating water tank and the insulation water tank by setting the first valve, the second valve, the first water pump, and the second water pump, thereby helping to achieve precise control of the water levels and water levels of the two water tanks, ensuring the user's water needs while reducing power consumption.

The third valve 7075 is used to allow external water to flow into the heating water tank 701 under the control of the controller 703 .

[0140] Specifically, when the heating water tank 701 needs to be replenished with water and heated, the controller 703 can control the third valve 7075 to open, so that water from the outside flows into the heating water tank 701 to replenish the heating water tank 701 with water.

[0141] By setting the third valve, when the water in the heating water tank is insufficient, water can be replenished to the heating water tank in time to ensure sufficient hot water supply.

[0142] In some optional implementations, such as Fig. 9 As shown, the system further includes a heating water level sensor 708 (L2) and / or a heat preservation temperature sensor 709 (T2).

[0143] The heating water level sensor 708 is arranged in the heating water tank 701, and is used for collecting the water level of the heating water tank 701. The heat preservation temperature sensor 709 is arranged in the heat preservation water tank 702, and is used for collecting the water temperature of the heat preservation water tank 702.

[0144] The controller 703 is further configured to perform at least one of the following operations:

[0145] Operation 1: If the water level of the insulated water tank 702 is greater than or equal to the preset upper water level limit, or the water level of the heating water tank 701 is less than or equal to the preset lower water level limit, the water replenishing device 707 is controlled to stop the water circulation of the insulated water tank 702 and start the water circulation of the heating water tank 701.

[0146] Operation 2, if the current water temperature of the insulated water tank 702 is lower than the third preset temperature, the water replenishing device 707 and the heat pump unit 704 are controlled to heat the water in the insulated water tank 702 according to the third preset operating frequency until the water temperature of the insulated water tank 702 reaches the fourth preset temperature.

[0147] For the specific description of the above operation 1 and operation 2, please refer to the above method embodiment, which will not be repeated here.

[0148] This embodiment controls the water levels of the two water tanks by setting a heating water level sensor and / or an insulation temperature sensor, thereby avoiding resource waste or insufficient water supply caused by the water level exceeding the normal range. When the water temperature in the insulation water tank 702 is too low, the water in the insulation water tank 702 is heated separately, so that the water in the insulation water tank 702 is heated first and hot water is provided to the user in time.

[0149] In some optional implementations, such as Fig. 9 As shown, the heat pump unit 704 includes an electric auxiliary heating device 7041, an inlet water temperature sensor 7042 (T3) and an outlet water temperature sensor 7043 (T4), and the inlet water temperature sensor 7042 and the outlet water temperature sensor 7043 are used to collect the inlet water temperature and the outlet water temperature of the heat pump unit 704; the electric auxiliary heating device 7041, the inlet water temperature sensor and the outlet water temperature sensor are all connected to the controller 703;

[0150] The controller 703 is also used for:

[0151] If the current air temperature is less than or equal to the preset auxiliary heating air temperature threshold, the heating power of the electric auxiliary heating device 7041 is determined based on the temperature difference between the inlet water temperature and the outlet water temperature, and according to the heating power, the electric auxiliary heating device 7041 is controlled to perform electric auxiliary heating on the water in the heat pump unit 704.

[0152] Regarding the control method of the electric auxiliary heating device, reference can be made to the contents of the above method embodiment, which will not be repeated here. This embodiment realizes that when the temperature is low, the heat pump unit is electrically assisted to heat by electric auxiliary heating, so that the water temperature is quickly increased and the heating efficiency is improved.
