It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0028] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0032] This disclosure provides a method and apparatus for preventing condensation, as well as a computer-readable storage medium, which can reduce condensation and ensure equipment safety.

[0033] Figure 1 A flowchart illustrating an anti-condensation control method according to some embodiments of the present disclosure is shown.

[0034] like Figure 1 As shown, the anti-condensation control method includes steps S1-S3. In some embodiments, the anti-condensation control method is performed by an anti-condensation control device.

[0035] In step S1, in response to the current liquid supply temperature being lower than the current dew point temperature of the battery box, the anti-condensation mode is activated.

[0036] For example, if the supply temperature (i.e., the coolant delivery temperature) is not lower than the current dew point temperature inside the battery compartment, the anti-condensation mode will not be activated. If the supply temperature is lower than the current dew point temperature inside the battery compartment, the anti-condensation mode will be activated.

[0037] In some embodiments, the electric heating assembly includes a positive temperature coefficient (PTC) heating element. Due to the self-regulating characteristics (temperature self-limiting) of the PTC element, it will not overheat, making it safer and more reliable.

[0038] Figure 2 A schematic diagram of electric heating according to some embodiments of the present disclosure is shown.

[0039] like Figure 2 As shown, the PCT bracket 300 is located outside the liquid supply pipe 200, and the PCT heating element 100, for example, consists of 6 groups, located outside the PCT bracket 300. When the electric heating assembly is turned on, it can heat the coolant transported in the pipe.

[0040] Those skilled in the art should understand that the electric heating method for coolant is not limited to the examples above. Other methods can be used to heat the coolant as needed, which will not be elaborated here.

[0041] In some embodiments, the anti-condensation control method further includes: acquiring the current dry-bulb temperature and wet-bulb temperature inside the battery box; and determining the current dew point temperature of the battery box based on the dry-bulb temperature and wet-bulb temperature.

[0042] For example, the supply liquid temperature is obtained through a temperature sensor, and the dry-bulb and wet-bulb temperatures inside the battery compartment are obtained through a temperature and humidity sensor. Then, the dew point temperature can be obtained by looking up tables based on the dry-bulb and wet-bulb temperatures. The condensation temperature is determined based on the dry-bulb and wet-bulb temperatures, thereby automatically controlling condensation prevention.

[0043] In some embodiments, the current dry-bulb and wet-bulb temperatures inside the battery compartment are acquired at specified intervals to update the current dew point temperature of the battery compartment.

[0044] For example, a specified period of 5 seconds means that the dry-bulb temperature, wet-bulb temperature, and supply liquid temperature are measured every 5 seconds. By setting a reasonable detection period, system fluctuations caused by frequent fluctuations in the acquired signals such as temperature and humidity can be avoided. In other words, the system should not be allowed to operate frequently on a second-by-second basis, which could lead to inaccurate actions or failure to trigger.

[0045] In step S2, in anti-condensation mode, the coolant is heated using an electric heating element. The electric heating element rapidly heats the coolant, increasing the supply temperature and preventing condensation. Using an electric heating element to prevent condensation is not only highly efficient but also energy-saving and environmentally friendly, reducing costs.

[0046] In some embodiments, the anti-condensation control method further includes: in anti-condensation mode, in response to the current dew point temperature of the battery box decreasing at a rate greater than a specified temperature decreasing rate, performing at least one of the following: reducing the operating frequency of the compressor; reducing the coolant supply flow rate.

[0047] For example, a microcomputer records the changes in dew point temperature within the battery compartment. The temperature change per minute is calculated as the rate of decrease in dew point temperature. A specified rate of decrease is given, for example, 5°C per minute. If the dew point temperature decreases by 5°C or more per minute, a sudden change in dew point temperature is identified. If the dew point temperature within the battery compartment does not suddenly drop, the composite anti-condensation mode is not activated. If the dew point temperature within the battery compartment suddenly drops, the composite anti-condensation mode is activated. In addition to heating the coolant with the electric heating element, the composite anti-condensation mode further reduces the compressor's operating frequency and / or reduces the coolant supply flow rate. Through these multiple measures, the composite anti-condensation mode can rapidly increase the supply coolant temperature, thereby effectively reducing condensation.

[0048] The following explains the principle of preventing condensation by adjusting the compressor's operating frequency. The compressor in the cooling system has a fixed structure and a fixed cylinder size. The compressor's displacement is V = nv, where V is the compressor's displacement, n is the compressor's rotational speed, and v is the compressor's cylinder volume. With other conditions remaining constant, a lower compressor operating frequency results in a smaller compressor displacement. Therefore, by adjusting the compressor's operating frequency, the cooling capacity of the refrigeration system is reduced, and the liquid supply temperature of the liquid cooling system increases. This ensures that the liquid supply temperature is not lower than the dew point temperature inside the battery compartment, thus preventing condensation.

[0049] The following explains the principle of preventing condensation by adjusting the operating frequency of the variable frequency water pump. According to the heat transfer formula Q = cmΔt, where Q is the heat, C is the specific heat capacity, m is the mass, and Δt is the temperature increase (or decrease). By reducing the liquid supply flow rate, the cooling capacity can be reduced, Δt increases, and the liquid supply temperature is kept at or above the dew point temperature inside the battery compartment.

[0050] In some embodiments, reducing the coolant supply flow rate includes reducing the operating frequency of the variable frequency water pump. The variable pump operating frequency ensures that the anti-condensation mode does not easily fail, balancing anti-condensation functionality and cost.

[0051] In step S3, under specified conditions, the input power of the electric heating element is reduced at a specified heating decrease rate. For example, if the specified conditions are met and the requirement for a rise in the liquid supply temperature is not urgent, the input power of the electric heating element is reduced, thereby saving energy and reducing costs. Furthermore, if the electric heating element operates at full load and overload for a long time, the heat generated in the circuit increases, the circuit will age faster, and may even cause accidents. By reducing the input power of the electric heating element when the specified conditions are met, the service life of the electric heating element can be extended and safety hazards can be reduced.

[0052] In some embodiments, the specified condition is that the anti-condensation mode has been running for a specified duration. For example, if the electric heating element has been running for a period of time, meaning the coolant has been heated for a period of time and the condensation situation has improved to a certain extent, then the input power of the electric heating element can be reduced, thereby saving energy and reducing costs.

[0053] In some embodiments, specifying a heating decrease rate includes a first heating decrease rate and a second heating decrease rate. Reducing the input power of the electric heating component at the specified heating decrease rate includes: reducing the input power of the electric heating component at the first heating decrease rate when the difference between the current supply liquid temperature and the current dew point temperature of the battery box is greater than a first temperature difference threshold; and reducing the input power of the electric heating component at the second heating decrease rate when the difference between the current supply liquid temperature and the current dew point temperature of the battery box is not greater than the first temperature difference threshold, wherein the first heating decrease rate is less than the second heating decrease rate.

[0054] For example, the first heating rate decreases by x watts every 10 minutes, and the second heating rate decreases by x watts every 5 minutes. When the difference between the dew point temperature and the supply liquid temperature is greater than 5°C (i.e., the dew point temperature is 5°C lower than the supply liquid temperature), the input power of the electric heating element decreases by x watts every 10 minutes. When the difference between the dew point temperature and the supply liquid temperature is no greater than 5°C, the input power of the electric heating element decreases by x watts every 5 minutes.

[0055] By gradually reducing the input power of the electric heating element, the coolant can be heated quickly when the temperature difference between the dew point temperature and the supply temperature is large, preventing condensation. At the same time, the power of the electric heating element can be reduced when the temperature difference between the dew point temperature and the supply temperature is small, saving energy and extending the service life of the electric heating element.

[0056] In some embodiments, reducing the operating frequency of the variable frequency water pump includes: reducing the operating frequency of the variable frequency water pump at a first water pump descent rate when the difference between the current supply liquid temperature and the current dew point temperature of the battery box is greater than a third temperature difference threshold; and reducing the operating frequency of the variable frequency water pump at a second water pump descent rate when the difference between the current supply liquid temperature and the current dew point temperature of the battery box is not greater than the third temperature difference threshold, wherein the first water pump descent rate is greater than the second water pump descent rate.

[0057] For example, the first water pump decreases its frequency by 5 Hz every 5 minutes, and the second water pump decreases its frequency by 5 Hz every 10 minutes. When the difference between the dew point temperature and the supply liquid temperature is greater than 5°C, the power of the variable frequency water pump decreases by 5 Hz every 5 minutes; when the difference is no greater than 5°C, the power of the variable frequency water pump decreases by 5 Hz every 10 minutes. By using variable frequency water pumps and gradually slowing down the rate of decrease in coolant flow, condensation can be prevented while ensuring the supply liquid flow rate remains within a reasonable range, thus guaranteeing the refrigeration cycle.

[0058] In some embodiments, reducing the operating frequency of the compressor includes: reducing the operating frequency of the inverter compressor at a first compression reduction rate when the difference between the current liquid supply temperature and the current dew point temperature of the battery box is greater than a second temperature difference threshold; and reducing the operating frequency of the inverter compressor at a second compression reduction rate when the difference between the current liquid supply temperature and the current dew point temperature of the battery box is not greater than the second temperature difference threshold, wherein the first compression reduction rate is greater than the second compression reduction rate.

[0059] For example, the first compression rate is a decrease of 5 Hz every 5 minutes, and the second compression rate is a decrease of 5 Hz every 10 minutes. When the difference between the dew point temperature and the liquid supply temperature is greater than 5°C, the power of the variable frequency compressor decreases by 5 Hz every 5 minutes; when the difference between the dew point temperature and the liquid supply temperature is no greater than 5°C, the power of the variable frequency compressor decreases by 5 Hz every 10 minutes. By gradually slowing down the rate of power reduction of the variable frequency compressor, condensation can be prevented while ensuring normal circulation of refrigerant in the system, thus guaranteeing the cooling function.

[0060] When the electric heating element is on and measures are taken to reduce the operating frequency of the variable frequency compressor and / or variable frequency water pump, i.e., when a composite anti-condensation mode is used, the input power of the electric heating element is reduced at regular intervals, and the rate of reduction of the operating frequency of the variable frequency compressor and / or variable frequency water pump is gradually slowed down. There are several main situations.

[0061] When the difference between the dew point temperature and the supply liquid temperature is greater than 5°C, the input power of the electric heating element decreases by x watts every 10 minutes, and the power of the variable frequency water pump decreases by 5 Hz every 5 minutes.

[0062] When the difference between the dew point temperature and the supply liquid temperature is greater than 5°C, the input power of the electric heating element decreases by x watts every 10 minutes, and the power of the variable frequency compressor decreases by 5 Hz every 5 minutes.

[0063] When the difference between the dew point temperature and the supply liquid temperature is greater than 5°C, the input power of the electric heating element decreases by x watts every 10 minutes, and the power of the variable frequency water pump decreases by 5 Hz every 5 minutes, and the power of the variable frequency compressor decreases by 5 Hz every 5 minutes.

[0064] When the difference between the dew point temperature and the supply liquid temperature is no more than 5°C, the input power of the electric heating element decreases by x watts every 5 minutes, and the power of the variable frequency water pump decreases by 5 Hz every 10 minutes.

[0065] When the difference between the dew point temperature and the liquid supply temperature is no more than 5°C, the input power of the electric heating element decreases by x watts every 5 minutes, and the power of the variable frequency compressor decreases by 5 Hz every 10 minutes.

[0066] When the difference between the dew point temperature and the supply liquid temperature is no more than 5°C, the input power of the electric heating element decreases by x watts every 5 minutes, and the power of the variable frequency water pump decreases by 5Hz every 10 minutes, and the power of the variable frequency compressor decreases by 5Hz every 10 minutes.

[0067] In some embodiments, the anti-condensation mode is turned off when the current supply temperature is higher than the dew point temperature and the difference between the supply temperature and the dew point temperature is greater than a fourth temperature difference threshold.

[0068] For example, if the liquid supply temperature is already higher than the dew point temperature by a certain degree, the anti-condensation mode will be turned off in time, the electric heating component will stop heating, and the liquid supply flow rate and compressor power will be adjusted to a suitable level, thereby achieving automated anti-condensation and avoiding resource waste.

[0069] According to some embodiments of the present disclosure, the anti-condensation control method prevents condensation by electrically heating the coolant and reduces the power of the electric heating component when specified conditions are met. This not only achieves anti-condensation at a lower cost but also extends the service life of the component and reduces safety hazards.
