Description

Technical Field

[0001] The embodiments of the present invention relate to the field of air conditioning technology, and in particular to a method, device, system and storage medium for integrated control of air conditioners and water heaters. Background Technology

[0002] With the rapid development of society, economy, and technology, people have increasingly higher requirements for air conditioners and water heaters. Traditionally, an air conditioner indoor unit is paired with an outdoor unit, or a water heater tank is paired with an outdoor unit. This increases installation and maintenance costs for users and occupies more space. Therefore, to avoid these drawbacks, existing technology has developed multi-split air conditioning and water heater integrated units.

[0003] Multi-split air conditioning and water heater integrated units can simultaneously operate the air conditioner for cooling and the water heater for heat recovery, making full use of the high-temperature exhaust gas and improving energy efficiency. Therefore, how to achieve efficient integration and control of the combined cooling and hot water supply mode of air conditioning and water heaters has become an urgent problem to be solved.

[0004] Currently, in the use of air conditioning water heaters, when users set the air conditioner to cool and the water heater to heat (i.e., a combined cooling and hot water supply mode), the multi-split air conditioning water heater system will transfer the energy generated by the air conditioner's cooling to the water heater to meet the energy demand for hot water. However, if too few indoor units are turned on or the cooling capacity of the indoor units is too low, energy cannot be efficiently transferred to the water heater, thus failing to meet the family's water needs. If too many indoor units are turned on or the cooling capacity of the indoor units is too high, the excess energy demand cannot be effectively distributed, resulting in excessive load on the unit and compromising the overall reliability of the system. Furthermore, due to the prevalence of inverter air conditioners, the time during which a household needs the cooling unit to operate at high load is very limited. Once the indoor temperature reaches the user's desired temperature, the indoor units will operate at low load, causing a sharp increase in cooling capacity upon startup, followed by a low cooling level after reaching the desired temperature. Moreover, as the water temperature rises, the heat exchange capacity of the water heater decreases, and the water heater cannot efficiently receive the heat transferred from the air conditioner's indoor units. Therefore, how to efficiently control the cooling capacity of air conditioners and the heating capacity of water heaters is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0018] Please see Figure 1 and combined Figures 5-7 ,in, Figure 1 This is a flowchart illustrating an integrated control method for an air conditioner and a water heater provided in an embodiment of the present invention, specifically including steps S101 to S106.

[0019] S101. Obtain the first heat exchange parameters of the indoor unit 1 and the second heat exchange parameters of the outdoor unit 2 of the air conditioner, respectively, and obtain the third heat exchange parameters of the water heater and the third heat exchange parameters of the water heater 3. S102. Obtain the cooling capacity of the air conditioner based on the first heat exchange parameter and the second heat exchange parameter, and obtain the heating capacity of the water heater 3 based on the third heat exchange parameter. S103. Set the energy loss threshold range by combining the first heat exchange parameter, the second heat exchange parameter and the third heat exchange parameter; S104. Determine whether the difference between the cooling capacity and the heating capacity is within the energy loss threshold range, and obtain the determination result; S105. Adjust the cooling capacity of the air conditioner and / or the heating capacity of the water heater 3 according to the judgment result, so that the heating temperature of the water heater 3 reaches the set temperature.

[0020] This embodiment determines the cooling capacity of the air conditioner and the heating capacity of the water heater 3 by acquiring the heat exchange parameters of the indoor unit 1, outdoor unit 2, and water heater 3. At the same time, it sets an energy loss threshold range. Then, by comparing the numerical difference between the cooling capacity and the heating capacity with the energy loss threshold range, it determines what kind of regulation to apply to the air conditioner or the water heater 3. This allows the air conditioner and the water heater 3 to operate in an efficient manner, thereby improving the control effect of the cooling capacity of the air conditioner and the heating capacity of the water heater 3, and thus improving the reliability of the integrated air conditioner and water heater 3 system.

[0021] In one embodiment, such as Figure 2 As shown, step S105 includes steps S201 to S202.

[0022] S201. When the numerical difference is not within the energy loss threshold range, adjust the cooling capacity of the air conditioner or the heating capacity of the water heater 3 so that the numerical difference is within the energy loss threshold range. S202. When the numerical difference is within the energy loss threshold range, the cooling capacity generated by the air conditioner is directly input into the water heater 3, and the difference between the cooling capacity and the heating capacity is further determined to be within the energy loss threshold range until the heating temperature of the water heater 3 reaches the set temperature.

[0023] In this embodiment, when adjusting the cooling capacity of the air conditioner and / or the heating capacity of the water heater 3 based on a judgment result, the judgment result refers to the difference between the cooling capacity and the heating capacity being within the energy loss threshold range, or the difference being outside the energy loss threshold range. Then, the cooling capacity of the air conditioner or the heating capacity of the water heater 3 is adjusted accordingly based on whether the difference is within the energy loss threshold range, thereby meeting the needs of using the air conditioner and water heater 3 together. Specifically, when the difference between the cooling capacity and the heating capacity is not within the energy loss threshold range, the cooling capacity or heating capacity is adjusted so that the difference is within the energy loss threshold range. When the difference between the cooling capacity and the heating capacity is within the energy loss threshold range, the cooling capacity generated by the air conditioner is input into the water heater 3 to bring the water heater 3 to the set temperature.

[0024] In one embodiment, step S102 includes: Calculate the cooling capacity Q within the preset time interval using the following formula. c : Q c =W*C*(T1-T2) Where W represents indoor airflow, C represents specific heat capacity, T1 represents indoor ambient temperature before the preset time interval, and T2 represents indoor ambient temperature after the preset time interval. Calculate the heat output Q within the preset time interval using the following formula. h : Q h =C*q m *(T) in -T out ) Among them, T in and T out q represents the inlet and outlet temperatures of the refrigerant pipes in the water tank of water heater 3, respectively. m This indicates the refrigerant flow rate through the water tank of the water heater.

[0025] In this embodiment, the first heat exchange parameter, the second heat exchange parameter, and the third heat exchange parameter specifically include indoor air flow, indoor ambient temperature, inlet and outlet temperatures of the refrigerant pipe in the water tank of the water heater 3, and refrigerant flow rate in the water tank of the water heater 3, etc. Therefore, the cooling capacity of the air conditioner and the heating capacity of the water heater 3 can be calculated based on the above parameters.

[0026] In another embodiment, step S103 includes: The energy loss threshold Q within a preset time interval is calculated using the following formula: Q=K1A1(T1-T e1 )+K2A2(T2-Te2 )+K3A3(T3-T e3 )+K4A4(T4-T e4 ) Wherein, K1 represents the heat transfer coefficient of the outdoor section of the pipe connecting to water heater 3, K2 represents the heat transfer coefficient of the indoor section of the pipe connecting to water heater 3, K3 represents the heat transfer coefficient of the outdoor section of the pipe connecting to indoor unit 1, K4 represents the heat transfer coefficient of the indoor section of the pipe connecting to indoor unit 1, A1 represents the heat transfer area of ​​the pipe wall of the outdoor section of the pipe connecting to water heater 3, A2 represents the heat transfer area of ​​the pipe wall of the indoor section of the pipe connecting to water heater 3, A3 represents the heat transfer area of ​​the pipe wall of the outdoor section of the pipe connecting to indoor unit 1, A4 represents the heat transfer area of ​​the pipe wall of the indoor section of the pipe connecting to indoor unit 1, T1 represents the pipe temperature of the outdoor section of the pipe connecting to water heater 3, T2 represents the pipe temperature of the indoor section of the pipe connecting to water heater 3, T3 represents the pipe temperature of the outdoor section of the pipe connecting to indoor unit 1, T4 represents the pipe temperature of the indoor section of the pipe connecting to indoor unit 1, T... e1 This indicates the ambient temperature (T) of the outdoor section of pipe 3 connected to the water heater. e2 This indicates the ambient temperature (T) of the indoor section of pipe 3 connected to the water heater. e3 This indicates the ambient temperature (T) of the outdoor section of the pipes connected to indoor unit 1. e4 This indicates the ambient temperature of the indoor section of the pipes connected to indoor unit 1; The heat transfer coefficients are adjusted according to the preset heat transfer coefficient range to obtain the energy loss threshold range corresponding to the energy loss threshold.

[0027] In this embodiment, the heat exchange parameters, in addition to the aforementioned indoor ambient temperature, refrigerant pipe inlet temperature, and outlet temperature of the water tank of the water heater 3, may also include the pipe temperature of the connecting pipe between the indoor unit 1 and the water heater 3, the pipe temperature of the connecting pipe between the indoor unit 1 and the outdoor unit 2, the pipe temperature of the connecting pipe between the outdoor unit 2 and the water heater 3, the heat transfer coefficient of each connecting pipe, the heat transfer area, and the ambient temperature, etc. Therefore, the energy loss threshold Q is obtained by setting these parameters. Then, by adjusting the heat transfer coefficient, the energy loss threshold changes, thereby obtaining the corresponding energy loss threshold range ΔQ. In this way, the operating status of the indoor unit 1, the outdoor unit 2, and the water heater 3 can be determined by the relationship between the cooling capacity, heating capacity, and the energy loss threshold range, and the operating status of the three can be controlled accordingly to improve the control effect of the air conditioner's cooling capacity and the water heater 3's heating capacity.

[0028] In one embodiment, step S201 includes: When the numerical difference is greater than the maximum value of the energy loss threshold range, the opening step of the electronic expansion valve of the water heater 3 is increased, and after the increase, it is determined whether the numerical difference is within the energy loss threshold range. If the numerical difference is still greater than the maximum value of the energy loss threshold range, the opening step of the electronic expansion valve of the water heater 3 is adjusted to the maximum critical value, and the preset exhaust value of the water heater 3 is increased until the numerical difference is within the energy loss threshold range.

[0029] When the numerical difference between cooling capacity and heating capacity is not within the energy loss threshold range, it has two meanings: First, the numerical difference between cooling capacity and heating capacity must be greater than the maximum value of the energy loss threshold range, i.e., Q. c -Q h >△Q max Secondly, the numerical difference between cooling capacity and heating capacity must be less than the minimum value of the energy loss range threshold, Q. c -Q h <△Q min .

[0030] In this embodiment, if the difference between the cooling capacity and the heating capacity is greater than the maximum value of the energy loss range threshold, it indicates that the heat exchange capacity of the water heater 3 has deteriorated due to the rise in water temperature, or that the cooling capacity of the air conditioner is much greater than the heating capacity of the water heater 3 due to the large number of air conditioner indoor units being turned on or the air conditioner indoor units operating at high frequency. In other words, the heating capacity of the water heater 3 cannot meet the high cooling capacity, so it is necessary to increase the heating capacity of the water heater 3. Specifically, as shown in the example... Figure 5 As shown, the electronic expansion valve of water heater 3 is opened a preset number of steps. At this time, indoor unit 1 and outdoor unit 2 are normally connected, and indoor unit 1, outdoor unit 2 and water heater 3 are also normally connected. The heat exchanger 21 and compressor 22 of outdoor unit 2 are both working normally. Afterwards, the heat exchange parameters are reacquired, and the determination of ΔQ continues. min ≤Q c -Q h ≤△Q max Does this hold true? If it still does, Q c -Q h >△Q max Then, continue to increase the opening of the electronic expansion valve until it reaches the highest critical value. Simultaneously, after reaching the maximum opening, execute the command to increase the exhaust temperature, gradually increasing the preset exhaust value of water heater 3. During this process, the determination of △Q continues. min ≤Q c -Q h ≤△Q max Is it true? If it is still Q... c -Q h >△Q maxThen the heat exchanger 21 of outdoor unit 2 will be converted into a condenser to assist in heat dissipation, until Q... c -Q h It is located in △Q.

[0031] In another embodiment, step S201 further includes: When the numerical difference is less than the minimum value of the energy loss threshold range, the outdoor unit 2 is controlled to switch from heat exchange mode to evaporation mode, and the numerical difference is continuously judged to be within the energy loss threshold range until the numerical difference is within the energy loss threshold range.

[0032] In this embodiment, if the numerical difference between the cooling capacity and the heating capacity is less than the minimum value of the energy loss range threshold, it indicates that the heat exchange capacity of the water heater 3 is strong, and the cooling capacity of the air conditioner cannot meet the requirements. Therefore, it is necessary to turn on the heat exchanger 21 of the outdoor unit 2, such as... Figure 6 As shown, the heat exchanger 21 of outdoor unit 2 is operated as an evaporator, and the heat exchanger 21 of outdoor unit 2 remains connected to the water heater 3, thereby increasing the cooling capacity of the air conditioner. During this process, the determination of ΔQ continues. min ≤Q c -Q h ≤△Q max Whether it is true or not, until Q c -Q h Finally landed on △Q min With △Q max Within the range.

[0033] In one embodiment, step S202 includes: The outdoor unit 2 is controlled to stop working, and the cooling capacity generated by the air conditioner is transferred to the water heater 3; The system monitors the heating temperature of water heater 3 in real time. Once the water heater 3 reaches the set temperature, it stops working and controls the air conditioner to operate in an independent normal working state.

[0034] In this embodiment, when the numerical difference between the cooling capacity and the heating capacity is within the energy loss threshold range, i.e., ΔQ min ≤Q c -Q h ≤△Q max When the outdoor unit 2 is established, the heat exchanger 21 of the outdoor unit 2 does not participate in the operation, such as Figure 7 As shown, the heat exchanger 21 of outdoor unit 2 is neither connected to indoor unit 1 nor to water heater 3 at this time. The cooling capacity generated by indoor unit 1 of the air conditioner is directly output to water heater 3. Of course, during this process, the determination of ΔQ continues. min ≤Q c -Q h ≤△Q maxThe system operates until the water temperature in water heater 3 reaches the user's preset temperature, at which point water heater 3 is shut down. After water heater 3 shuts down, the heat exchanger 21 of outdoor unit 2 begins operation, consistent with normal air conditioner operation, which will not be elaborated further here.

[0035] In a specific embodiment, the real-time detection of the heating temperature of the water heater 3 until the heating temperature of the water heater 3 reaches the set temperature includes: Obtain the current heating temperature of water heater 3; The current heating temperature is added to the preset target heating temperature to obtain the target heating temperature threshold. The target heating temperature threshold is set to fluctuate based on a preset temperature fluctuation value to obtain the target heating temperature threshold range, and the target heating temperature threshold range is used as the exhaust interval. Select any target heating temperature threshold from the exhaust zone and use it as the set temperature.

[0036] This embodiment constructs the exhaust zone of water heater 3 based on the water temperature of water heater 3, a preset target heating temperature, and temperature fluctuation values. This gives the heating process of water heater 3 a clear boundary; that is, when water heater 3 heats up to the set temperature within the exhaust zone, it can be considered that the heating of water heater 3 has met the usage requirements, and further heating can be stopped. For example, if the current heating temperature is T... w Let the target heating temperature be X. Therefore, the target heating temperature threshold T = T w -X, further, the temperature fluctuation value is Y, then the exhaust range △T can be obtained as TY≦△T≦T+Y.
