Description

TECHNICAL FIELD

[0001] The present application relates to the field of temperature control, and in particular to a heating time calculation method and device, a storage medium and an electronic device. BACKGROUND

[0002] The variable frequency heating device refers to a device that automatically adjusts the working power according to the actual situation, so that the object being heated can maintain a constant temperature. The general non-variable frequency heating device is a device that automatically adjusts the heating time by setting different temperatures and performs heat preservation. The variable frequency heating device not only has better heating effect, but also has the functions of reducing power consumption and loss because its working principle is to change the power supply frequency to adjust the load, and has a longer service life than the non-variable frequency heating device.

[0003] However, since the working frequency of the variable frequency heating device is in a changing state, it is difficult to calculate the time for heating the object to the set temperature when using the variable frequency heating device for heating. For example, when using the variable frequency heating device to heat the pool water, if the function of providing the user with the heating time required by the pool cannot be provided, the user cannot know the heating time required by the pool during the use of the variable frequency heating device, and cannot properly select the time to start the variable frequency heating device. When the user starts the variable frequency heating device too early, the pool water temperature reaches the set temperature in advance before the use time of the pool, and the variable frequency heating device needs to continue to maintain the pool water at the set temperature, which consumes more energy and causes waste. When the user starts the variable frequency heating device too late, the pool water temperature cannot reach the set temperature within the expected use time, and the user experience is poor. SUMMARY

In other words, since the working frequency of the variable-frequency heating device is not constant and changes due to the influence of the ambient temperature and the object temperature of the target object, the embodiments of the present application determine the heat differences between sub-heat output by the heating device and sub-heat dissipated by the target object in the sub-periods, fully consider the influence of the heat differences in the sub-periods on sub-heat output by the heating device and sub-heat dissipated by the target object in the next sub-period, so as to improve the accuracy of calculating the time required for the variable-frequency heating device to heat the object to the set temperature, and greatly improve the user experience.

Obviously, the described embodiments only represent some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0030] The present application is described in detail below with reference to specific embodiments.

[0031] Variable frequency heating equipment automatically adjusts operating power based on actual conditions to maintain a constant temperature of the heated object. Conventional non-variable frequency heating equipment automatically adjusts heating time and maintains heat by setting different temperatures. Variable frequency heating equipment not only provides better heating results, but also, because it operates by varying the power supply frequency to adjust the load, reduces power consumption and losses, resulting in a longer lifespan than non-variable frequency heating equipment.

[0032] In one embodiment, Figure 1 , which is a schematic diagram of a scenario in which a heating device according to an embodiment of the present application heats a target object. In this embodiment, the heating device 101 includes at least a condensing device 1011 and a compression device 1012. The heating device 101 is configured to heat the target object 103 from an initial temperature to a set temperature set by the user based on user input instructions. For example, if the target object 103 is swimming pool water, the heating device 101 heats the pool water entering the compression device 1012 and further injects the heated pool water into the swimming pool until the pool water temperature reaches the set temperature set by the user. In this embodiment, the heating device 101 is a variable frequency heating device.

[0033] In the heating scenario provided in this embodiment, the outlet temperature of the condensing device T co Sensor 1021, condensing device outlet pressure P co Sensor 1022, condensing device inlet temperature T ciSensor 1023, condensing device inlet pressure P ci Sensor 1024, compression device suction temperature T s Sensor 1025, compression device suction pressure P s Sensor 1026, ambient temperature T3 Sensor 1027 and object temperature T1 of target object 103 Sensor 1028.

[0034] Condensing device outlet temperature T co Sensor 1021, condensing device outlet pressure P co Sensor 1022, condensing device inlet temperature T ci Sensor 1023 and condensing device inlet pressure P ci Sensor 1024 is arranged near condensing device 1011, and is used to collect outlet temperature T co , outlet pressure P co , inlet temperature T ci and inlet pressure P ci of condensing device 1011 respectively. Compression device suction temperature T s Sensor 1025, compression device suction pressure P s Sensor 1026 is arranged near compression device 1012, and is used to collect suction temperature T s and suction pressure P s of compression device 1012 respectively. Object temperature T1 Sensor 1028 of target object is arranged near or on the surface of target object 103, or arranged on heating device 101, and is used to collect object temperature T1 of target object 103. Ambient temperature T3 Sensor 1027 is arranged near heating device 101, and is used to collect ambient temperature of heating device 101.

[0035] It can be understood that the above is only an exemplary embodiment provided by the embodiment of the present application, and heating device 101 at least includes condensing device 1011 and compression device 1012, and can further include throttling device, evaporation device and pipeline connecting multiple devices, etc. Heating device 101 does not include the above multiple temperature sensors and pressure sensors, and in another embodiment, heating device 101 can include the above multiple temperature sensors and pressure sensors or other any one or more devices required for performing heating work.

[0036] However, since the working frequency of the variable frequency heating device is in a state of change, it is difficult to calculate the time for heating the object to the set temperature when heating is performed using the variable frequency heating device. For example, when heating pool water using the variable frequency heating device, if the function of providing the user with the heating time required by the pool cannot be provided, the user cannot know the heating time required by the pool in the process of using the variable frequency heating device, and cannot properly select the time of starting the variable frequency heating device. When the user starts the variable frequency heating device too early, the pool water temperature reaches the set temperature in advance before the use time of the pool, and the variable frequency heating device needs to continue to maintain the pool water at the set temperature, which consumes more energy and causes waste. When the user starts the variable frequency heating device too late, the pool water temperature cannot reach the set temperature within the expected use time, and the user experience is poor.

[0037] Therefore, in order to solve the above problems, the embodiment of the present application provides a method for calculating the required heating time of a target object by a variable frequency heating device. In one embodiment, as shown in the figure, a flowchart of a heating time calculation method provided by the embodiment of the present application is shown. The method can be implemented by relying on a computer program and can run on a heating time calculation device based on the von Neumann system. The computer program can be integrated in an application or can run as an independent tool application. Figure 2

[0038] Specifically, the heating time calculation method comprises:

[0039] S101, obtaining the environment temperature corresponding to each of a plurality of sub-time periods in a preset time period.

[0040] The determination method of the required time for the heating device to heat the target object from the initial temperature to the set temperature is the ratio of the difference between the heat required for the object temperature of the target object to rise from the initial temperature to the set temperature and the heating power of the heating device and the heat dissipation power of the target object. Specifically, the determination of the required heating time comprises the following formula:

[0041]

[0042] Wherein, t is the time required for heating the target object from the initial temperature to the set temperature, the unit is h, Q is the total heat required for heating the target object from the initial temperature to the set temperature, P1 is the output power of the heating device, and P2 is the heat dissipation power of the target object.

[0043] However, since the output power of the heating device is affected by the environment temperature and the object temperature of the target object, the heat dissipation power of the target object is also affected by the difference between the current object temperature and the environment temperature, so the above formula cannot completely express the time required for heating the target object from the initial temperature to the set temperature.

[0044] ​Therefore, in the embodiment, the heat difference between the sub-heat output by the heating device and the sub-heat dissipated by the target object in each sub-time period is determined, and the number of sub-time periods required for accumulating the heat difference to the total heat is obtained by determining the heat required for heating the target object from the initial temperature to the set temperature, and therefore the time required for heating the target object from the initial temperature to the set temperature is determined according to the number of sub-time periods and the length of the sub-time period.

[0045] Specifically, the ambient temperature corresponding to each of the plurality of sub-time periods in the preset time period is obtained. For example, the ambient temperature corresponding to each of the plurality of sub-time periods can be obtained by publicly obtaining the ambient temperature change curve or a discrete set of ambient temperature data of the preset time period published by the meteorological bureau, or other forms of ambient temperature data. The preset time period can be a time period of any length, and the length of the preset time period can be determined by the length preset in the memory of the heating device, or set by the user as needed when starting to perform the heating task. For example, the user inputs the length of the preset time period to the heating device through the input device of the heating device, and the input method includes touch, voice, remote control, etc., and the input device of the heating device includes an interactive display screen, a keyboard, a mouse, a remote control, etc.

[0046] The length of each of the plurality of sub-time periods in the preset time period can be the same or different. For example, the length of the preset time period is 12 hours, and the length of each sub-time period is 0.5 hours, so the preset time period includes 24 sub-time periods. For another example, the length of the plurality of sub-time periods increases in order from near to far, the length of the preset time period is 12 hours, the length of the initial sub-time period is 0.5 hours, the length of the second sub-time period is 0.6 hours, and the length of the third sub-time period is 0.7 hours. For another example, the length of the plurality of sub-time periods decreases in order from near to far, the length of the preset time period is 12 hours, the length of the initial sub-time period is 1 hour, the length of the second sub-time period is 0.9 hours, the length of the third sub-time period is 0.8 hours, and the length of the fourth sub-time period is 0.7 hours.

[0047] In the embodiment, by reasonably setting the length of each of the plurality of sub-time periods, the calculation of the heat difference corresponding to each sub-time period can be more accurate and more in line with the actual working conditions of each heating device. For example, as the object temperature of the target object approaches the set temperature, the output power of the heating device will fluctuate around a lower power value, and therefore the length of the plurality of sub-time periods is set to increase in order from near to far, thereby reducing the calculation of the heat difference corresponding to the later sub-time period, saving the calculation logic resources of the heating device, and improving the efficiency of determining the heating time.

[0048] S102, determine the heat difference value between the sub-heat output by the heating device and the sub-heat dissipated by the target object according to the environment temperature corresponding to each of the plurality of sub-time periods.

[0049] According to the output power of the heating device corresponding to the sub-time period and the heat dissipation power of the target object, the sub-heat output by the heating device and the sub-heat dissipated by the target object corresponding to the sub-time period can be obtained respectively, so as to determine the heat difference value between the sub-heat output by the heating device and the sub-heat dissipated by the target object. The heat dissipation power of the target object is determined by the difference between the object temperature of the target object and the environment temperature, and the output power of the heating device is determined by the environment temperature and the object temperature of the target object.

[0050] As shown in Figure 3 , taking the environment temperature change curve as an example, Figure 3 is a coordinate diagram of time and environment temperature provided by an embodiment of the present application, and the environment temperature corresponding to each of the plurality of sub-time periods is obtained according to the environment temperature change curve L of the preset time period, for example, the sub-time period H1 corresponds to the environment temperature T 31 , the sub-time period H2 corresponds to the environment temperature T 32 , the sub-time period H3 corresponds to the environment temperature T 33 , and the sub-time period H n corresponds to the environment temperature T 3n .

[0051] Among them, the sub-time period H1 corresponds to the heat difference value Q1=t1×(P 11 —P 21 ), t1 is the time length corresponding to the sub-time period H1, P 11 is the output power of the heating device corresponding to the sub-time period H1, and P 21 is the heat dissipation power of the target object corresponding to the sub-time period H1. The sub-time period H2 corresponds to the heat difference value Q2=t2×(P 11 —P 21 ), t2 is the time length corresponding to the sub-time period H2, P 12 is the output power of the heating device corresponding to the sub-time period H2, and P 22 is the heat dissipation power of the target object corresponding to the sub-time period H2. The sub-time period H3 corresponds to the heat difference value Q3=t3×(P 13 —P 23 ), t3 is the time length corresponding to the sub-time period H3, P 13 is the output power of the heating device corresponding to the sub-time period H3, and P 23 is the heat dissipation power of the target object corresponding to the sub-time period H3. The sub-time period H4 corresponds to the heat difference value Q4=t4×(P 14 —P 24 ), t4 is the time length corresponding to the sub-time period H4, P14 is the output power of the heating equipment corresponding to the sub-time period H4, P 24 is the heat dissipation power of the target object corresponding to the sub-time period H4.

[0052] S103. Obtain the heat required for the sub-time period when the multiple heat differences are accumulated to a total heat according to the heat differences corresponding to the multiple sub-time periods. The total heat is the heat required to heat the target object from the initial temperature to the set temperature.

[0053] The total heat is the amount of heat required to heat the target object from its initial temperature to its set temperature. Specifically, the amount of heat required to heat the target object from its initial temperature to its set temperature can be calculated based on the size and specific heat capacity of the target object. The total heat Q required to heat the target object from its initial temperature to its set temperature is given by the following formula:

[0054] Q = c × V × ρ2 × (T2 - T1);

[0055] Where c is the specific heat capacity of the target object, unit is kJ / (m 2 ·℃), V is the volume of the target object, unit is m 3 , ρ2 is the density of the target object, unit is kg / m 3 , T2 is the set temperature, unit ℃, T 11 is the starting temperature of the target object, in °C.

[0056] According to the heat difference corresponding to multiple sub-time periods, such as Figure 2 As shown, the heat difference between the sub-heat output of the heating device and the sub-heat dissipated by the target object in each of the multiple sub-time periods is calculated. When n satisfies the following formula, the target value of n is obtained:

[0057] Q1+Q2+Q3…+Q n-1 <Q≤Q1+Q2+Q3…+Q n-1 +Q n ;

[0058] In other words, the target value n is obtained when the sum of the heat differences in n-1 sub-time periods is less than the total heat Q and the heat differences in n sub-time periods are greater than or equal to the total heat Q. For example, if n is 3, the duration t1 corresponding to sub-time period H1 = the duration t2 corresponding to sub-time period H2 = the duration t3 corresponding to sub-time period H3 = 0.5 hours, and the time required to heat the target object from the initial temperature to the set temperature is t = nt1 = 1.5 hours.

[0059] The embodiment of the present application determines the heat difference between the sub-heat output by the heating device and the sub-heat dissipated by the target object in each sub-time period corresponding to the environment temperature, and obtains the number of sub-time periods required for accumulating the heat difference to the total heat by determining the heat required for heating the target object from the initial temperature to the set temperature, so as to determine the time required for heating the target object from the initial temperature to the set temperature according to the number of sub-time periods and the time length of the sub-time period; in other words, since the working frequency of the variable frequency heating device is not constant and changes due to the influence of the environment temperature and the object temperature of the target object, the embodiment of the present application calculates the heat difference between the sub-heat output by the heating device and the sub-heat dissipated by the target object in the sub-time period, fully considers the influence of the heat difference in the sub-time period on the sub-heat output by the heating device and the sub-heat dissipated by the target object in the next sub-time period, so as to improve the accuracy of calculating the time required for the variable frequency heating device to heat the object to the set temperature, and greatly improves the user experience.

[0060] In one embodiment, as shown in Figure 4 FIG. 1 is a flowchart of a heating time calculation method provided by the embodiment of the present application. The method can be implemented by relying on a computer program and can be run on a heating time calculation device based on the von Neumann system. The computer program can be integrated in an application or run as an independent tool application.

[0061] Specifically, the heating time calculation method comprises:

[0062] S201, according to the environment temperature change curve of the preset time period and the actual environment temperature corresponding to the starting sub-time period, taking the actual environment temperature as the environment temperature corresponding to the starting sub-time period.

[0063] Since the obtained environment temperature change curve is a predicted value of the environment temperature of the future preset time period, and may be the environment temperature value of the outdoor environment, the obtained environment temperature curve may be quite different from the environment temperature in which the heating device works. For example, the target object is the pool water of an indoor swimming pool, and the obtained environment temperature curve corresponds to the environment temperature change value of the outdoor environment. Therefore, the embodiment of the present application corrects the environment temperature change curve by collecting the actual environment temperature corresponding to the starting sub-time period. It can be understood that when a discrete set of environment temperature data or other forms of environment temperature data in the preset time period is obtained instead of the environment temperature change curve, the environment temperature in the plurality of sub-time periods can also be corrected by the following steps, which are not limited by the present application.

[0064] In the embodiment, the plurality of sub-time periods include a starting sub-time period and at least one non-starting sub-time period. The starting sub-time period can be understood as the first sub-time period when the heating device starts heating. The processor collects the actual ambient temperature where the heating device and the target object are located through the ambient temperature sensor, for example, as shown in Figure 1 the ambient temperature T 31 collected by the ambient temperature T3 sensor 1027.

[0065] S202, correcting the ambient temperature change curve according to the actual ambient temperature to determine the ambient temperature corresponding to each of the at least one non-starting sub-time period in the preset time period.

[0066] According to the difference between the actual ambient temperature corresponding to the starting sub-time period and the predicted ambient temperature corresponding to the ambient temperature change curve, the ambient temperature change curve is corrected to determine the ambient temperature corresponding to each of the at least one non-starting sub-time period in the preset time period.

[0067] As shown in Figure 5 , Figure 5 is a flowchart for correcting the ambient temperature provided by the embodiment of the present application. According to the plurality of predicted ambient temperatures determined by the ambient temperature change curve L, the predicted ambient temperature T 41 corresponding to the starting sub-time period H1, the predicted ambient temperature T 42 corresponding to the non-starting sub-time period H2, the predicted ambient temperature T 43 corresponding to the non-starting sub-time period H3, …, and the predicted ambient temperature T n corresponding to the non-starting sub-time period H. 4n

[0068] Further, the ambient temperature correction value T0 between the actual ambient temperature T 31 collected by the ambient temperature T3 sensor in the starting sub-time period H1 and the predicted ambient temperature T 41 is obtained. Therefore, the ambient temperature T 32 corresponding to the non-starting sub-time period H2 is T 42 + T0, the ambient temperature T 33 corresponding to the non-starting sub-time period H3 is T 43 + T0, the ambient temperature T n corresponding to the non-starting sub-time period H is T 3n + T0. 4n

[0069] S203, determining the sub-heat output by the heating device corresponding to the sub-time period and the sub-heat dissipated by the target object according to the ambient temperature corresponding to the sub-time period and the object temperature corresponding to the target object.

[0070] ​​Specifically, the sub-heat dissipated by the target object in the sub time period is determined according to the difference between the environment temperature corresponding to the sub time period and the object temperature of the target object; the operation parameter of the heating device corresponding to the sub time period is determined according to the environment temperature corresponding to the sub time period and the object temperature of the target object; and the sub-heat output by the heating device corresponding to the sub time period is determined according to the operation parameter of the heating device corresponding to the sub time period.

[0071] In the embodiment, the operation parameter of the heating device corresponding to the non-starting sub time period is determined according to the object temperature difference between the object temperature of the target object corresponding to the non-starting sub time period and the object temperature of the target object corresponding to the previous sub time period adjacent to the non-starting sub time period, and the environment temperature difference between the environment temperature corresponding to the non-starting sub time period and the environment temperature corresponding to the previous sub time period adjacent to the non-starting sub time period.

[0072] In other words, the operation parameter includes a first operation parameter and a second operation parameter, the first operation parameter is affected by the object temperature, and the second operation parameter is affected by the environment temperature. In one embodiment, as shown in Figure 1 The heating device 101 includes a condensing device 1011 and a compression device 1012, the first operation parameter at least includes one of the following: the condensing device outlet temperature T co1 , the condensing device outlet pressure P co1 , the condensing device inlet temperature T ci1 , and the condensing device inlet pressure P ci1 ; and the second operation parameter at least includes one of the following: the compression device suction temperature T s , and the compression device suction pressure P s . It can be understood that, Figure 1 The structure of the heating device shown in the figure is only schematic, and the heating device shown in the embodiments of the present application can also include other devices, in other words, the operation parameter of the heating device can also include other types of operation parameters, which are set by the user as needed.

[0073] Specifically, the plurality of sub time periods correspond to a starting sub time period and at least one non-starting sub time period, the sub-heat output by the heating device corresponding to the starting sub time period and the sub-heat dissipated by the target object are determined according to the environment temperature corresponding to the starting sub time period and the object temperature of the target object.

[0074] The environment temperature corresponding to the starting sub time period and the object temperature of the target object are the actual environment temperature and the object temperature of the target object collected by the sensor, for example, as shown in Figure 1 The environment temperature corresponding to the starting sub time period is collected by the environment temperature T3 sensor 1027, and the object temperature T 11 of the target object is collected by the object temperature T1 sensor 1028 of the target object, the condensing device outlet temperature T co sensor 1021, the condensing device outlet pressure P coSensor 1022, condensing device inlet temperature T ci Sensor 1023, condensing device inlet pressure P ci Sensor 1024, compression device suction temperature T s Sensor 1025, compression device suction pressure P s Sensor 1026, condensing device outlet temperature T co1 , condensing device outlet pressure P co1 , condensing device inlet temperature T ci1 , condensing device inlet pressure P ci1 , compression device suction temperature T s1 , compression device suction pressure P s1 .

[0075] Further, through the refrigerant property parameter data table stored in the memory, and the condensing device outlet temperature T co1 , condensing device outlet pressure P co1 , condensing device inlet temperature T ci1 , condensing device inlet pressure P ci1 , the enthalpy difference DH1 corresponding to the starting sub-time period is obtained, including:

[0076] DH1 = Hi1 - Ho1;

[0077] Wherein, Hi1 is the inlet specific enthalpy of the condensing device, which is obtained by querying the refrigerant property parameter data table through the condensing device inlet temperature T ci1 and the condensing device inlet pressure P ci1 , unit kJ / kg, Ho1 is the outlet specific enthalpy of the condensing device, which is obtained by querying the refrigerant property parameter data table through the condensing device outlet temperature T co1 , condensing device outlet pressure P co1 , unit kJ / kg.

[0078] Through the related parameters of the compression device and the compression device suction temperature T s1 , compression device suction pressure P s1 , the suction density of the compression device is obtained by looking up the refrigerant property parameter data table, and then the flow rate M1 of the compression device is calculated using the formula, including:

[0079] M1 = F × D × ρ1 × η v ;

[0080] Wherein, M1 is the flow rate of the compression device, unit kg / s, F, D and η v are respectively the running parameter acquisition value (unit r / s) of the compression device, the rated displacement (unit cm 3r), volumetric efficiency of the compression device, the suction gas saturation density ρ1 is the suction gas temperature T s1 , the compression device suction pressure P s1 In the refrigerant property parameter data table, the unit is kg / m 3 .

[0081] Further, the enthalpy difference DH1 and the flow M get the output power P 11 of the heating device, including:

[0082] P 11 = DH1 x M1;

[0083] P 11 is the output power of the heating device in the initial sub-period, the unit is kW.

[0084] According to the ambient temperature corresponding to the initial sub-period and the object temperature of the target object, the heat dissipation power P 21 of the target object corresponding to the initial sub-period is determined, including:

[0085] P 21 =kxs(T 11 -T 31 );

[0086] k is the heat dissipation coefficient of the target object, the unit is kJ / (m 2 ·℃), s is the area of the target object, the unit is m 2 .

[0087] According to the output power P 11 of the heating device corresponding to the initial sub-period and the heat dissipation power P 21 of the target object, the heat difference Q1 between the sub-heat output by the heating device and the sub-heat dissipated by the target object corresponding to the initial sub-period is obtained, including:

[0088] Q1=t1x(P 11 -P 21 );

[0089] The ambient temperature and the object temperature of the target object corresponding to the starting sub-time period are actual values ​​collected, and the ambient temperature and the object temperature of the target object corresponding to the non-sub-time period are predicted values. Specifically, when the sub-time period is a non-starting sub-time period, the sub-heat output by the heating device and the sub-heat dissipated by the target object corresponding to each sub-time period are determined based on the ambient temperature and the object temperature of the target object corresponding to the sub-time period, including: determining the object temperature of the target object corresponding to the non-starting sub-time period based on the heat difference corresponding to the previous sub-time period adjacent to the non-starting sub-time period and the object temperature of the target object; determining the sub-heat output by the heating device and the sub-heat dissipated by the target object corresponding to the non-starting sub-time period based on the object temperature of the target object and the ambient temperature.

[0090] In other words, after obtaining the heat difference value for the previous sub-period and the target object's temperature for the current sub-period, the object temperature for the current sub-period is calculated by taking into account the effect of the heat difference value for the previous sub-period on the object temperature. Therefore, the heat dissipation power of the target object for the current sub-period can be calculated based on the difference between the object temperature for the current sub-period and the ambient temperature, thereby determining the target object's heat dissipation power for the current sub-period.

[0091] Furthermore, after obtaining the heat difference value for the previous sub-time period and the target object's object temperature for the current sub-time period, the operating parameters of the heating device corresponding to the sub-time period are determined based on the target object's object temperature and ambient temperature corresponding to the current sub-time period, the target object's object temperature and ambient temperature corresponding to the previous sub-time period adjacent to the current sub-time period, and the ambient temperature difference. Therefore, the output power of the heating device and, therefore, the sub-heat output of the heating device are determined based on the operating parameters of the heating device corresponding to the current sub-time period.

[0092] like Figure 6 As shown, Figure 6 This is a flow chart of determining the output power of a heating device provided by an embodiment of the present application. In the starting sub-time period H1, the object temperature T is collected. 11 and ambient temperature T 31 , through the object temperature T 11 Determine the first operating parameter: condensing device outlet temperature T co1 , condensing device outlet pressure P co1 , condensing device inlet temperature T ci1 , condensing device inlet pressure P ci1 , through the ambient temperature T 31 Determine the second operating parameter: the suction temperature T of the compression device s , compression device suction pressure P sThus, the output power P of the heating device corresponding to the starting sub-period H1 is obtained. 11 .

[0093] Further, in the non-starting sub-period H2, and the non-starting sub-period H2 is adjacent to the starting sub-period H1, the first operating parameter corresponding to the non-starting sub-period H2 is determined by the object temperature difference (T 12 -T 11 ), and the second operating parameter corresponding to the non-starting sub-period H2 is determined by the environment temperature difference (T 32 -T 31 ), thus the output power P of the heating device corresponding to the non-starting sub-period H2 is obtained. 12 .

[0094] The output power P of the heating device corresponding to the non-starting sub-period H3 adjacent to the starting sub-period H2 is obtained according to the above. 13 According to the above, details are not repeated here.

[0095] S204, according to the sub-heat output by the heating device corresponding to each of the plurality of sub-periods and the sub-heat dissipated by the target object, determine the heat difference value corresponding to each of the plurality of sub-periods.

[0096] According to the output power of the heating device corresponding to the sub-period and the heat dissipation power of the target object, the sub-heat output by the heating device corresponding to the sub-period and the sub-heat dissipated by the target object can be obtained respectively, thus the heat difference value between the sub-heat output by the heating device and the sub-heat dissipated by the target object is determined. As shown in Figure 3 details are not repeated here.

[0097] S205, according to the heat difference value corresponding to each of the plurality of sub-periods, obtain the number of sub-periods required for accumulating the plurality of heat difference values to the total heat, and the total heat is the heat required for heating the target object from the initial temperature to the set temperature.

[0098] Referring to S103, details are not repeated here.

[0099] The embodiment of the present application determines the heat difference between the sub-heat output by the heating device and the sub-heat dissipated by the target object in each sub-time period corresponding to the environmental temperature, and obtains the number of sub-time periods required for accumulating the heat difference to the total heat by determining the heat required for the target object to heat from the initial temperature to the set temperature, so as to determine the time required for the target object to heat from the initial temperature to the set temperature according to the number of required sub-time periods and the length of the sub-time period. In other words, since the working frequency of the variable frequency heating device is not constant and changes due to the influence of the environmental temperature and the object temperature of the target object, the embodiment of the present application calculates the heat difference between the sub-heat output by the heating device and the sub-heat dissipated by the target object in each sub-time period, fully considers the influence of the heat difference in the sub-time period on the sub-heat output by the heating device and the sub-heat dissipated by the target object in the next sub-time period, so as to improve the accuracy of calculating the time required for the variable frequency heating device to heat the object to the set temperature, and greatly improves the user experience.

[0100] In one embodiment, as shown in Figure 7 , a flowchart of a heating time calculation method provided by the embodiment of the present application is shown.

[0114] DH1=Hi1-Ho1;

[0115] Wherein, Hi1 is the inlet specific enthalpy of the condensing device, which is obtained by querying the refrigerant property parameter data table through the condensing device inlet temperature T ci1 and the condensing device inlet pressure P ci1 , unit kJ / kg, Ho1 is the outlet specific enthalpy of the condensing device, which is obtained by querying the refrigerant property parameter data table through the condensing device outlet temperature T co1 , the condensing device outlet pressure P co1 , unit kJ / kg.

[0116] Through the related parameters of the compression device and the compression device suction temperature T s1 , the compression device suction pressure P s1 , the suction density of the compression device is obtained by looking up the refrigerant property parameter data table, and then the flow rate M1 of the compression device is calculated using the formula, including:

[0123] According to the ambient temperature corresponding to the starting sub-time period and the object temperature of the target object, determine the heat dissipation power P 21 of the target object corresponding to the starting sub-time period, including:

[0124] P 21 =kxs(T 11 -T 31 );

[0125] k is the heat dissipation coefficient of the target object, unit: kJ / (m 2 ·℃), s is the area of the target object, unit: m 2 .

[0126] S308, according to the sub-heat dissipated by the target object and the sub-heat dissipated by the target object corresponding to the starting sub-time period, determine the heat difference corresponding to the starting sub-time period.

[0127] According to the output power P 11 of the heating device corresponding to the starting sub-time period and the heat dissipation power P 21 of the target object, obtain the heat difference Q1 between the sub-heat dissipated by the target object and the sub-heat dissipated by the target object corresponding to the starting sub-time period, including:

[0128] Q1=t1x(P 11 -P 21 ).

[0129] S309, according to the heat difference corresponding to the previous sub-time period adjacent to the non-starting sub-time period and the object temperature of the target object, determine the object temperature of the target object corresponding to the non-starting sub-time period.

[0130] Taking the first non-initiator time period adjacent to the initiator time period as an example, the heat difference of the initiator time period is Q1, and thus the object temperature of the target object corresponding to the first non-initiator time period is:

[0131]

[0132] wherein V is the volume of the target object, in m 3 , and p2 is the density of the target object, in kg / m 3 .

[0133] S310, according to the object temperature difference and the environment temperature difference between the object temperature corresponding to the non-initiator time period and the object temperature corresponding to the previous time period adjacent to the non-initiator time period and the environment temperature corresponding to the non-initiator time period and the environment temperature corresponding to the previous time period adjacent to the non-initiator time period, determine the operation parameter of the heating device corresponding to the time period.

[0134] Specifically, the object temperature difference of the target object is (T 12 -T 11 ), and the environment temperature difference is (T 32 -T 31 ).

[0135] The condenser inlet temperature corresponding to the non-initiator time period H2 is T ci2 =T ci1 +(T 12 -T 11 );

[0136] The condenser inlet pressure P ci2 =[p ci1 corresponding to the saturation temperature + (T 12 -T 11 ) corresponding to the saturation pressure;

[0137] The condenser outlet temperature is T co2 =T co1 +(T 12 -T 11 );

[0138] The condenser outlet pressure P co2 =[p co1 corresponding to the saturation temperature + (T 12 -T 11 ) corresponding to the saturation pressure;

[0139] Thus, the enthalpy difference DH2 corresponding to the non-initiator time period H2 is obtained.

[0140] The compressor suction temperature corresponding to the non-initiator time period H2 is T s2 =T s1 +(T 32 -T31 );

[0141] Condensing device suction pressure P s2 = [p s1 Corresponding saturated temperature + (T 32 -T 31 ) corresponding saturated pressure;

[0142] Therefore, the saturated suction density p 12 corresponding to the non-initial sub-period H2 is obtained.

[0143] S311, according to the operating parameters of the heating device corresponding to the non-initial sub-period, determine the sub-heat output by the heating device corresponding to the non-initial sub-period.

[0144] After obtaining the enthalpy difference DH2 and the saturated suction density p 12 corresponding to the non-initial sub-period H2, the output power P 12 of the heating device corresponding to the non-initial sub-period H2 is determined, including:

[0145] P 12 = DH2 x M2 = DH2 x F x D x p 12 x eta v ;

[0146] Therefore, the sub-heat Q2 output by the heating device corresponding to the non-initial sub-period H2 is t2 x P 12 , t2 is the duration corresponding to the non-initial sub-period H2.

[0147] SS12, according to the difference between the ambient temperature and the object temperature of the target object corresponding to the non-initial sub-period, determine the sub-heat lost by the target object corresponding to the non-initial sub-period.

[0148] Taking the non-initial sub-period H2 as an example, the object temperature corresponding to the first non-initial sub-period H2 is:

[0149]

[0150] According to the ambient temperature and the object temperature of the target object corresponding to the non-initial sub-period H2, the heat dissipation power P 22 of the target object corresponding to the non-initial sub-period H2 is determined, including:

[0151] P 22 = k x s x (T 12 -T 32 ) ;

[0152] k is the heat dissipation coefficient of the target object, unit kJ / (m 2 ·℃), s is the area of the target object, unit m 2 .

[0153] S313: Determine a heat difference corresponding to the non-starting sub-time period according to the sub-heat output by the heating device and the sub-heat dissipated by the target object corresponding to the non-starting sub-time period.

[0154] Taking the non-starting sub-time period H2 as an example, the heat dissipation power P of the target object corresponding to the non-starting sub-time period H2 is 22 and the output power P of the heating equipment 11 , the heat difference corresponding to the non-starting sub-time period H2 includes:

[0155] Q2=t2×(P 12 -P 22 );

[0156] Similarly, the non-starting sub-time period H n The corresponding object temperature is:

[0157]

[0158] The difference in the object temperature of the target object is (T 1n -T 1n-1 ), the difference in ambient temperature is (T 3n -T 3n-1 ).

[0159] Non-starting sub-time period H n The corresponding condensing unit inlet temperature is:

[0160] T cin =T cin-1 +(T 1n -T 1n-1 );

[0161] The inlet pressure of the condensing unit is:

[0162] P cin =[p cin The corresponding saturation temperature + (T 1n -T 1n-1 )] corresponding to the saturation pressure;

[0163] The outlet temperature of the condensing device is:

[0164] T con =T con-1 +(T 1n -T 1n-1 );

[0165] The outlet pressure of the condensing unit is:

[0166] P con =[p con-1 The corresponding saturation temperature + (T 1n-T 1n-1 the corresponding saturated pressure;

[0167] Therefore, the enthalpy difference DH n corresponding to the non-initial time period H2 is obtained.

[0168] The non-initial time period H n corresponding to the compression device suction temperature is

[0169] T sn = T sn-1 + (T 3n -T 3n-1 );

[0170] The condensing device suction pressure is:

[0171] P sn = [p sn-1 corresponding to the saturated temperature + (T 3n -T 3n-1 )] corresponding to the saturated pressure;

[0172] Therefore, the enthalpy difference DH n corresponding to the non-initial time period H 1n is obtained. n corresponding to the saturated suction density p n , and the non-initial time period H 1n corresponding to the enthalpy difference DH n and the saturated suction density p 1n is determined.

[0173] The non-initial time period H n corresponding to the target object object temperature is:

[0176] P 2n = k × s × (T 1n -T 3n );

[0177] Therefore, the non-initial time period H n corresponding to the heat difference value is:

[0178] Q n = t n × (P 1n -P2n ).

[0179] S314, according to the plurality of sub-time periods each corresponding to the heat difference value, obtain the number of sub-time periods required to accumulate the plurality of heat difference values to the total heat, the total heat is the heat required to heat the target object from the initial temperature to the set temperature.

According to the ambient temperature T 12 and the object temperature T 32 of the non-starting sub-time period H2, and the object temperature T 32 is obtained according to the object temperature T 31 and the heat difference value Q1, the running parameter X2 is further obtained to obtain the output power P 12 of the heating device and the heat dissipation power P 22 of the target object, so as to obtain the heat difference value Q2 corresponding to the non-starting sub-time period H2, and the heat difference value Q n corresponding to the non-starting sub-time period H n is obtained in turn. When the following formula is satisfied, the target value of n is obtained:

[0182] Q1+Q2+Q3…+Q n-1 <Q≤Q1+Q2+Q3…+Q n-1 +Q n ;

[0183] In other words, that is, when the cumulative value of the heat difference values of n-1 sub-time periods is less than the total heat Q and the heat difference values of n sub-time periods are greater than or equal to the total heat Q, the target value of n is obtained. For example, n is 3, the time length t1 corresponding to the sub-time period H1 is t2 corresponding to the sub-time period H2 is t3 corresponding to the sub-time period H3 is 0.5 hours, and the time t required to heat the target object from the initial temperature to the set temperature is nt1=1.5 hours.
