Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a heat dissipation control method and a heat dissipation control system for a condenser. Background Art

[0002] Existing dehumidifiers and outdoor units use only a centrifugal or axial fan for condenser-side air delivery. This results in highly uneven wind speeds and temperatures near the condenser, resulting in poor heat exchange. Generally, high wind speeds dissipate heat quickly, while low wind speeds can lead to excessively high temperatures. When temperatures exceed normal limits, increased wind speeds are necessary to reduce temperatures. However, excessively high wind speeds, solely for rapid heat dissipation, increase energy consumption and compromise environmental performance. Summary of the Invention

[0015] The corresponding fan speed is controlled to increase according to the speed gear and run for a first preset time.

[0016] Optionally, the step of controlling the rotation speeds and operating times of the plurality of fans according to the wind speed difference and the air outlet temperature of each of the heat dissipation areas further includes the following steps:

[0022] Optionally, the step of controlling the corresponding fan speed and operating time according to the second temperature difference further includes the following steps:

[0023] When the second temperature difference is less than or equal to the third preset ratio of the highest air outlet temperatures of the plurality of heat dissipation areas, determining whether the plurality of air outlet temperatures are all within a preset temperature range;

[0024] If not, the corresponding fans with the air outlet temperatures higher than the preset temperature range among the plurality of fans are controlled to increase their speed according to the preset control strategy.

[0045] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

Therefore, the features defined as "first", "second" and "third" may explicitly or implicitly include at least one of the features, that is, include one or more of the features.

[0047] Figure 1 is a schematic flow chart of a heat dissipation control method for a condenser according to an embodiment of the present invention.

[0048] like Figure 1 As shown, in a specific embodiment, the heat dissipation control method of the condenser includes the following steps:

[0049] S100, obtaining outlet air speeds and outlet air temperatures of multiple heat dissipation areas near the condenser, where the multiple heat dissipation areas are air supply areas of multiple fans installed near the condenser;

[0050] S200, calculating the wind speed difference between the maximum and minimum wind speeds of the outlet wind speeds of the plurality of heat dissipation areas;

[0051] S300: Control the rotation speeds and operating times of the multiple fans according to the wind speed difference and the air outlet temperature of each heat dissipation area.

[0052] This embodiment can control the operation of multiple fans according to the air outlet speed and air outlet temperature of each heat dissipation area, ensuring that the wind speed and temperature of each heat dissipation area are relatively uniform, which is beneficial to the overall heat exchange of the condenser, can improve the heat exchange effect, and ensure energy saving and environmental protection.

[0053] Here, specifically, after the dehumidification mode of the device is turned on and running for a period of time, the outlet air temperature and outlet air speed of multiple heat dissipation areas are obtained, and multiple fans are used to dissipate heat from the condenser. In this embodiment, the device can be an air conditioner and a dehumidifier.

[0054] In this embodiment, it is equivalent to multiple fans dividing the heat dissipation area of the condenser into multiple areas, so that multiple fans dissipate heat for multiple areas respectively. Due to various reasons, the heat dissipation temperature of each area may be different. Therefore, through the above-mentioned logical control, different controls can be performed on the fans of multiple areas, which can meet the heat dissipation needs of different areas and achieve energy-saving effects.

[0055] Figure 2FIG. 1 is a schematic flow chart of a method for controlling heat dissipation of a condenser according to another embodiment of the present invention. Figure 2 As shown, in this embodiment, step S300 specifically includes the following steps:

[0056] Step S31, determining whether the wind speed difference is less than or equal to a first preset ratio a of the maximum value of the multiple wind speeds; if so, executing step S32; if not, executing step S41;

[0057] Step S32, determining whether the multiple air outlet temperatures are all within a preset temperature range; if not, executing step S33; if so, executing step S100 after the multiple fans have been running for a certain period of time;

[0058] Step S33: Control the fans corresponding to the outlet air temperatures higher than the preset temperature range to increase their speed according to a preset control strategy. Here, if the temperature is higher than the preset temperature range by 2°C, the heat dissipation area is considered to be an over-temperature area.

[0059] Step S41, determining whether the wind speed difference is greater than a first preset proportion a of the maximum value among the plurality of outlet wind speeds and less than or equal to a second preset proportion b of the maximum value; if so, executing step S42; if not, executing step S51;

[0060] Step S42, determining the air outlet temperature corresponding to the maximum air outlet speed and the air outlet temperature corresponding to the minimum air outlet speed in the plurality of heat dissipation areas;

[0061] Step S43, calculating a second temperature difference between the outlet air temperature corresponding to the maximum outlet air speed and the outlet air temperature corresponding to the minimum outlet air speed;

[0062] Step S44, controlling the speed and operating time of the corresponding fan according to the second temperature difference;

[0063] Step S51, determining whether the wind speed difference is greater than a second preset ratio b of the maximum value among the plurality of outlet wind speeds; if so, executing step S52;

[0064] Step S52: Control the fan speed corresponding to the minimum airflow speed in the plurality of heat dissipation zones to increase to a third preset value and run for a third preset time. Here, the third preset value and the third preset time are set according to specific needs.

[0065] Specifically, after step S52, return to step S43.

[0066] That is, after step S52, a second temperature difference between the outlet temperature corresponding to the maximum outlet wind speed and the outlet temperature corresponding to the minimum outlet wind speed is calculated, and finally the speed and operating time of the corresponding fan are controlled according to the second temperature difference.

[0067] Here, the first preset ratio a is any value between 8% and 12%. For example, it can be 8%, 10% or 12%. In a preferred embodiment, the first preset ratio a is 10%.

[0068] The second preset ratio b is any value between 28% and 32%, for example, 28%, 30% or 32%.

[0069] In a preferred embodiment, the second preset ratio b is 30%.

[0070] The third preset ratio c is any value between 8% and 12%, for example, 8%, 10% or 12%.

[0071] In a preferred embodiment, the third preset ratio c is 10%.

[0072] The preset temperature range is set according to the outdoor ambient temperature, and is generally 10℃ to 15℃ higher than the outdoor ambient temperature.

[0073] Figure 3 FIG. 1 is a schematic flow chart of a method for controlling heat dissipation of a condenser according to another embodiment of the present invention. Figure 3 As shown, in this embodiment, step S33 specifically includes the following steps:

[0074] Step S331, calculating a first temperature difference between the outlet air temperature of a fan corresponding to a plurality of outlet air temperatures that is higher than a preset temperature range and an upper limit value in the preset temperature range;

[0075] Step S332, determining a corresponding fan speed gear according to the first temperature difference;

[0076] Step S333: Control the corresponding fan speed to increase according to the speed gear and run for a first preset time period. Here, the first preset time period is set according to specific design requirements.

[0077] This embodiment can specifically increase the speed of fans in the over-temperature area instead of increasing the speed of all fans, thereby ensuring energy-saving effects.

[0078] Specifically, if the first temperature difference is large, the speed gear is increased, and if the first temperature difference is small, the speed gear is decreased. By increasing the fan speed in the overheated area based on the size of the first temperature difference, the temperature in the area can be quickly reduced to a preset temperature range, while also achieving the technical effect of energy conservation.

[0079] Figure 4 FIG. 1 is a schematic flow chart of a heat dissipation control method for a condenser according to another embodiment of the present invention. Figure 4As shown, in this embodiment, step S44 further includes the following steps:

[0080] Step S441, determining whether the second temperature difference is greater than a third preset ratio c of the highest air outlet temperatures of the plurality of heat dissipation regions; if so, executing step S442; if not, executing step S32;

[0081] Step S442: Control the fan speed corresponding to the minimum air outlet speed in the plurality of heat dissipation zones to increase to a second preset value and run for a second preset time. Here, the second preset value and the second preset time are set according to specific needs.

In this embodiment, the condenser heat dissipation control system 100 further includes a condenser 30 and multiple fans 20. The multiple fans 20 are evenly arranged in an array in front of or behind the condenser 30, thereby dividing the heat dissipation area of the condenser 30 into multiple areas according to the locations of the multiple fans 20. Air ducts 40 are provided around the multiple fans 20 for intake of air to drive the multiple fans 20 to rotate.

[0083] In this embodiment, the number of the multiple fans 20 is four, that is, the heat dissipation area of the condenser 30 is divided into four heat dissipation areas, so that the fans 20 in multiple areas can be controlled differently, which can meet the heat dissipation requirements of different areas and achieve energy-saving effects.

[0084] In this embodiment, the condenser heat dissipation control system 100 further includes multiple temperature sensors, each disposed on the outlet side of the condenser 30 to detect outlet air temperatures of the multiple heat dissipation zones. The multiple temperature sensors are aligned with the multiple fans 20.

[0085] The condenser heat dissipation control system 100 further includes a plurality of wind speed sensors mounted on the front or rear side of the condenser 30 to detect the wind speed at different areas of the condenser 30. The plurality of wind speed sensors are aligned with the positions of the plurality of fans 20.

The aforementioned computer program can be downloaded from a computer-readable storage medium to a corresponding computing / processing device or downloaded to a computer or external storage device via a network (e.g., the Internet, a local area network, a wide area network, and / or a wireless network).

[0087] For the purposes of the description of this embodiment, a "computer-readable medium" can be any device that can contain, store, communicate, propagate, or transmit a program for use with or in conjunction with an instruction execution system, device, or apparatus.

[0089] In this embodiment, the control module 10 is further configured to: when the wind speed difference is less than or equal to a first preset ratio a of the maximum value of multiple outlet wind speeds, if there is an outlet air temperature that is not within the preset temperature range, then the corresponding fan 20 among the multiple outlet air temperatures that is higher than the preset temperature range is controlled to increase the speed according to the preset control strategy.

[0090] In this embodiment, the control module 10 is further configured to: first calculate a first temperature difference between an outlet air temperature higher than a preset temperature range among multiple outlet air temperatures and an upper limit value in the preset temperature range, then determine a corresponding speed gear of the fan 20 according to the first temperature difference, and finally control the corresponding fan 20 speed to increase according to the speed gear.

The control module 10 controls the speed of the fan 20 in each heat dissipation zone based on the data, ensuring relatively uniform outlet air speed and temperature across the heat dissipation zones.
