Abstract

[0001] The embodiments of the present application relate to the field of electrical equipment, and specifically to a temperature regulating device and a water pump control method and device thereof. Background Art
[0002] Currently, the condensate in mobile air conditioners is mostly detected by measuring the water level. When the water level reaches a certain height, the water pump is turned on to reduce the condensate level and prevent it from overflowing. When the water pump is turned on, the speed of the water pump is fixed.
[0003] When an air conditioner has only a full-water level switch and no switch to control the water pump at all times, the water pump is always on during cooling mode. This method of controlling the water pump to run continuously at a fixed high speed during cooling mode not only causes the pump to run continuously and produce abnormal noise, but also shortens its service life. Therefore, further improvements and refinements to current water pump control methods are necessary. Summary of the Invention

[0047] The embodiment of the present application proposes a water pump control method for a temperature regulating device, wherein the temperature regulating device may include: an ambient temperature sensor, an ambient humidity sensor, and an evaporator temperature sensor; Figure 1 As shown, the method may include steps S101-S103:
[0048] S101, detecting the ambient temperature in real time by the ambient temperature sensor, detecting the ambient humidity in real time by the ambient humidity sensor, and detecting the evaporator temperature in real time by the evaporator temperature sensor;
[0049] S102, determining the dew point temperature and moisture content of the current environment based on the detected ambient temperature and ambient humidity;
[0050] S103 : Control the water pump according to the relationship between the evaporator temperature and the dew point temperature, or control the water pump according to the relationship between the evaporator temperature and the dew point temperature and the moisture content.
[0051] In an exemplary embodiment of the present application, the water pump speed of current air conditioners is fixed during operation in cooling mode. Continuously running the water pump at a high speed not only causes the water pump to produce abnormal noise but also shortens its service life. Therefore, an embodiment of the present application provides a temperature control device and a water pump control method thereof, aiming to address the drawbacks of currently available temperature control devices on the market, such as air conditioners, particularly portable air conditioners with only a single water level detection switch, such as loud noise and short water pump service life.
[0052] In an exemplary embodiment of the present application, the method may further include:
[0053] Before detecting the ambient temperature, the ambient humidity and the evaporator temperature, the compressor and the fan in the temperature regulating device are controlled to start.
[0054] In the exemplary embodiments of the present application, Figure 2 As shown, the temperature regulating device 1 may include a temperature and humidity detection unit 11, a central control unit 12, a water pump 13, a compressor 14 and a fan 15, wherein the temperature and humidity detection unit 11, the water pump 13, the compressor 14 and the fan 15 are respectively connected to the central control unit 12.
[0055] In the exemplary embodiment of the present application, after the temperature control device 1 is started, before implementing the solution of the embodiment of the present application, the compressor 14 and the fan 15 can be first ensured to ensure the normal operation of the temperature control device 1. At this time, the water pump 13 can be started, or the water pump 13 can be left unstarted and started when needed.
[0056] In an exemplary embodiment of the present application, the temperature and humidity detection unit 11 can be composed of one or more temperature sensors and humidity sensors. Therefore, one or more temperature sensors and humidity sensors can be first set in the temperature control device to detect the temperature and humidity inside the temperature control device, and / or the temperature and humidity of the environment in which the temperature control device is located.
[0057] In the exemplary embodiments of the present application, there is no restriction on the specific type, quantity, size, setting location, etc. of the temperature sensor and humidity sensor. Any temperature sensor and humidity sensor that can implement the embodiment of the present application is within the protection scope of the embodiment of the present application.
[0058] In exemplary embodiments of the present application, for example, the temperature sensor in the embodiment of the present application may include but is not limited to: an ambient temperature sensor and an evaporator temperature sensor, and the humidity sensor in the embodiment of the present application may include but is not limited to: an ambient humidity sensor.
[0059] In an exemplary embodiment of the present application, the ambient temperature sensor can be configured to detect ambient temperature T1, the ambient humidity sensor can be configured to detect ambient humidity Q1, and the evaporator temperature sensor can be configured to detect evaporator temperature T2 (in fact, it can be configured to detect the temperature of the evaporator coil).
[0060] In an exemplary embodiment of the present application, after the temperature regulating device is started, in the cooling mode, the ambient temperature T1, ambient humidity Q1, and evaporator temperature T2 detected by the above-mentioned temperature sensor and humidity sensor can be collected in real time to control the start and stop and speed of the water pump according to the ambient temperature T1, ambient humidity Q1, and evaporator temperature T2.
[0061] In an exemplary embodiment of the present application, the dew point temperature TL of the current environment and the moisture content d1 of the current environment may be determined first according to the detected ambient temperature T1 and ambient humidity Q1.
[0062] In the exemplary embodiments of this application, the dew point temperature refers to the temperature at which air cools to saturation, with neither water vapor content nor air pressure changing; figuratively speaking, it's the temperature at which water vapor in the air transforms into dewdrops. The moisture content indicates the specific amount of water vapor in the air. Therefore, based on the current dew point temperature TL, it can be determined whether the current evaporator coil temperature is too high. If the current evaporator coil temperature is too high, condensation cannot be generated, and thus, the condensation will not increase further. Consider retaining the condensation, i.e., not pumping it out via the water pump. If the current evaporator coil temperature is not high, condensation can continue to be generated, and thus, the condensation will increase further. To prevent the condensation from quickly filling up, retaining the condensation can be avoided, i.e., pumping it out via the water pump. Similarly, based on the current moisture content d1, it can be determined whether the current environment is sufficiently humid. If the current environment is not humid enough, the condensation can be retained to increase the ambient humidity. If the current environment is humid enough, the condensation can be removed, and the water pump can be activated to pump it out.
[0063] In an exemplary embodiment of the present application, determining the dew point temperature TL of the current environment according to the ambient temperature and the ambient humidity may include:
[0064] Determine the dew point temperature TL corresponding to the ambient temperature T1 and the ambient humidity Q1 according to a preset first mapping table;
[0065] The first mapping table may represent the correspondence between different ambient temperatures, different ambient humidity, and different dew point temperatures.
[0066] In an exemplary embodiment of the present application, the correspondence between different ambient temperatures, different ambient humidity and different dew point temperatures can be determined in advance through measurement, testing, experience, etc., and a first mapping table can be established based on the correspondence. When it is necessary to determine the corresponding dew point temperature TL based on the ambient temperature T1 and the ambient humidity Q1, or when it is necessary to determine the corresponding ambient temperature T1 based on the ambient humidity Q1 and the dew point temperature TL, or when it is necessary to determine the corresponding ambient humidity Q1 based on the ambient temperature T1 and the dew point temperature TL, the first mapping table can be directly called up, and the data corresponding to the intersection of the two known items can be determined by looking up the table as the third data to be queried.
[0067] In an exemplary embodiment of the present application, for example, if the ambient temperature T1 = 26 degrees Celsius and the ambient humidity Q1 = 60%, the dew point temperature TL = 17.7 degrees Celsius can be found through the first mapping table.
[0068] In an exemplary embodiment of the present application, determining the moisture content in the current environment according to the ambient temperature and the ambient humidity may include:
[0069] Determining the moisture content corresponding to the ambient temperature and the ambient humidity according to a preset second mapping table;
[0070] The second mapping table may represent the correspondence between different ambient temperatures T1, different ambient humidity Q1, and different moisture contents.
[0071] In an exemplary embodiment of the present application, the correspondence between different ambient temperatures T1, different ambient humidity Q1 and different moisture content d1 can be determined in advance through measurement, testing, experience, etc., and a second mapping table can be established based on the correspondence. When it is necessary to determine the corresponding moisture content d1 according to the ambient temperature T1 and the ambient humidity Q1, or when it is necessary to determine the corresponding ambient temperature T1 according to the ambient humidity Q1 and the moisture content d1, or when it is necessary to determine the corresponding ambient humidity Q1 according to the ambient temperature T1 and the moisture content d1, the second mapping table can be directly called up, and the data corresponding to the intersection of the two known items can be determined by looking up the table as the third data to be queried.
[0072] In an exemplary embodiment of the present application, for example, if the ambient temperature T1 = 26 degrees Celsius and the ambient humidity Q1 = 60%, the moisture content d1 = 28.8 g / kg (grams / kilogram) can be found through the second mapping table.
[0073] In an exemplary embodiment of the present application, after determining the dew point temperature TL, the detected evaporator temperature T2 can be compared with the dew point temperature TL, and the size relationship between the evaporator temperature T2 and the dew point temperature TL can be determined based on the comparison result of the two, so as to further control the start and stop and speed of the water pump based on the size relationship between the evaporator temperature T2 and the dew point temperature TL, because the size relationship between the evaporator temperature T2 and the dew point temperature TL can reflect whether the current evaporator coil temperature is too high.
[0074] In an exemplary embodiment of the present application, since the humidity content d1 of the environment can directly reflect whether the current environment is sufficiently humid, the start and stop and the speed of the water pump can also be directly controlled according to the humidity content d1.
[0075] In an exemplary embodiment of the present application, controlling the start and stop and / or speed of the water pump according to the relationship between the evaporator temperature T2 and the dew point temperature TL, as well as the moisture content d1, may include:
[0076] When the evaporator temperature T2 is greater than the dew point temperature TL, the water pump can be controlled to stop running;
[0077] When the evaporator temperature T2 is less than or equal to the dew point temperature TL, the start and stop and / or speed of the water pump can be controlled according to the moisture content d1.
[0078] In an exemplary embodiment of the present application, when the evaporator temperature T2 is greater than the dew point temperature TL, it indicates that the current temperature of the evaporator coil is too high, and it is possible to consider retaining condensed water to replenish steam through condensed water. Therefore, at this time, the water pump can be kept in a stopped state, or the water pump can be controlled to stop running so that the water pump no longer extracts condensed water.
[0079] In an exemplary embodiment of the present application, when the evaporator temperature T2 is less than or equal to the dew point temperature TL, it indicates that the current evaporator coil temperature is not too high, and therefore, condensate can be omitted. However, if the condensate level is not yet full, condensate can be temporarily retained, thereby controlling the water pump to be stopped. When condensate is not retained, that is, when the water pump is controlled to start pumping water, the pumping speed, that is, the rotational speed of the water pump, can also be further determined based on the current ambient humidity d1.
[0080] In an exemplary embodiment of the present application, controlling the start and stop and the speed of the water pump according to the moisture content d1 may include:
[0081] Comparing the moisture content d1 with a preset first moisture content threshold;
[0082] When the moisture content d1 is less than the first moisture content threshold, the moisture content d1 can be compared with a preset second moisture content threshold, and the start and stop and speed of the water pump can be controlled according to the magnitude relationship between the moisture content d1 and the second moisture content threshold; wherein the first moisture content threshold is greater than the second moisture content threshold;
[0083] When the moisture content d1 is greater than or equal to the first moisture content threshold, the water pump may be controlled to run at a first preset speed for a first preset time and then stop running.
[0084] In an exemplary embodiment of the present application, one or more moisture content thresholds may be preset to serve as a standard for detecting the size of the current ambient moisture content d1.
[0085] In the exemplary embodiments of the present application, there is no restriction on the specific number and value of the moisture content thresholds set, and different settings can be made according to different models, different judgment processes, different judgment schemes, scheme accuracy requirements, etc.
[0086] In an exemplary embodiment of the present application, the moisture content threshold may include a first moisture content threshold ds1 and a second moisture content threshold ds2 , and the first moisture content threshold ds1 may be set to be greater than the second moisture content threshold ds2 .
[0087] In an exemplary embodiment of the present application, the first moisture content threshold may meet the following conditions: 15-25 g / kg;
[0088] The first moisture content threshold may be 5-15 g / kg.
[0089] In an exemplary embodiment of the present application, the first moisture content threshold value may be selected as 20 g / kg; the first moisture content threshold value may be selected as 10 g / kg.
[0090] In an exemplary embodiment of the present application, the moisture content d1 can be first compared with the first moisture content threshold ds1, that is, the moisture content d1 of the current environment is first compared with a larger moisture content threshold (that is, the first moisture content threshold ds1) to determine whether the current environment is sufficiently humid.
[0091] In an exemplary embodiment of the present application, when the moisture content d1 is greater than or equal to the first moisture content threshold ds1, it indicates that the current environment is sufficiently humid, and the water pump can be controlled to operate at a higher speed for a certain period of time to begin pumping water. For example, the water pump can be controlled to operate at a first preset speed for a first preset period of time and then stop.
[0092] In the exemplary embodiment of the present application, the specific value of the first preset speed is not limited. The value of the first preset speed can be determined based on one or more factors such as different machine models, different current moisture contents, different differences between the moisture content d1 and the first moisture content threshold ds1, etc.
[0093] In an exemplary embodiment of the present application, the first preset speed may select the rated speed of the current water pump to quickly pump water.
[0094] In an exemplary embodiment of the present application, for example, the first preset rotation speed may be 3000 rpm-5000 rpm, and specifically may be 4000 rpm.
[0095] In an exemplary embodiment of the present application, when the moisture content d1 is less than the first moisture content threshold ds1, it indicates that the current environment is not humid enough. However, since the first moisture content threshold ds1 is relatively large, even if the moisture content d1 is less than the first moisture content threshold ds1, it cannot be said that the current environment is dry. Therefore, in order to further determine the humidity of the current environment, a smaller moisture content threshold, such as the second moisture content threshold ds2, can be used to compare with the detected moisture content d1 of the current environment, so as to further control the start and stop and speed of the water pump according to the size relationship between the moisture content d1 and the second moisture content threshold ds2.
[0096] In an exemplary embodiment of the present application, controlling the start and stop and the speed of the water pump according to the magnitude relationship between the moisture content d1 and the second moisture content threshold ds2 may include:
[0097] Comparing the moisture content d1 with the second moisture content threshold ds2;
[0098] When the moisture content d1 is greater than or equal to the second moisture content threshold ds2, the water pump can be controlled to run at a second preset speed for a second preset time and then stop running; the second preset speed is less than the first preset speed; the second preset time is greater than or equal to the first preset time;
[0099] When the moisture content d1 is less than the second moisture content threshold ds2, the water pump may be controlled to stop running.
[0100] In an exemplary embodiment of the present application, since the second moisture content threshold ds2 is a small moisture content threshold, when the moisture content d1 is less than the second moisture content threshold ds2, it can be determined that the current environment is already very dry. Therefore, condensed water can be retained to increase the ambient humidity, and the water pump can be controlled to stop running at this time.
[0101] In an exemplary embodiment of the present application, when the moisture content d1 is greater than or equal to the first moisture content threshold ds1, it indicates that the current environment is relatively dry, but not particularly dry. In this case, condensed water may be retained. Alternatively, condensed water may not be retained, but extraction of condensed water may be continued for a longer period of time to allow the condensed water to be retained for a period of time. Therefore, the water pump may be controlled to operate at a lower speed for a certain period of time to begin pumping water. For example, the water pump may be controlled to operate at a second preset speed for a second preset period of time and then stop.
[0102] In the exemplary embodiment of the present application, the specific value of the second preset speed is not limited. The value of the second preset speed can be determined based on one or more factors such as different machine models, different current moisture contents, different differences between the moisture content d1 and the second moisture content threshold ds1, etc.
[0103] In an exemplary embodiment of the present application, the second preset speed may be selected to be a speed lower than the rated speed of the current water pump, so as to reduce the pumping speed and retain the condensed water for a period of time.
[0104] In an exemplary embodiment of the present application, for example, the second preset rotation speed may be within a range of 1000 rpm to 3000 rpm, and specifically may be 2000 rpm.
[0105] In an exemplary embodiment of the present application, the second preset time period is greater than or equal to the first preset time period, which can ensure the retention time of the condensed water to increase the moisture content of the current environment.
[0106] In the exemplary embodiments of the present application, the above schemes can be summarized to show that the exemplary embodiments of the present application can determine whether the evaporator temperature T2 (i.e., the coil temperature) has reached the dew point temperature TL. When the evaporator temperature T2 is higher than the dew point temperature TL and no condensed water is produced, the water pump operation can be stopped. When the evaporator temperature T2 is lower than or equal to the dew point temperature TL, the water pump speed can be adjusted by determining the moisture content d1 in the ambient air. When the moisture content d1 is high, the water pump speed can be increased, and when the moisture content d1 is low, the water pump speed can be reduced.
[0107] The central control unit detects the current ambient temperature T1, evaporator coil temperature T2, and ambient humidity Q1 through the temperature and humidity detection unit. Using the current ambient temperature T1 and humidity Q1, the first and second mapping tables are used to calculate the current room's evaporator dew point temperature TL and the current ambient humidity content d1. When the evaporator coil temperature T2 exceeds the current dew point temperature TL, the water pump is controlled to stop. When the evaporator coil temperature T2 is lower than or equal to the dew point temperature TL, and the ambient humidity content d1 is greater than a preset first humidity threshold ds1, the water pump is controlled to operate at a preset rated speed (speed). When the ambient humidity content d1 is less than the first humidity threshold ds1 and greater than a preset second humidity threshold ds2, the water pump is controlled to reduce its speed to a second preset speed (speedL). When the ambient humidity content d1 is less than the second humidity threshold ds2, the water pump is controlled to stop. This method prevents the water pump from operating at high speed for extended periods, reduces abnormal noise generated by prolonged high-speed operation, and extends the pump's service life.
