Description

Technical Field

[0001] The present application relates to the technical field of equipment adjustment, and in particular to a sensor adjustment device for a refrigeration equipment performance test system and a refrigeration equipment performance test system. Background Art

[0002] In the performance test of refrigeration equipment, such as testing the power consumption and heating speed of refrigeration equipment, the ambient temperature is crucial to the test results. Therefore, during the test, a temperature sensor is usually set on the test platform to detect the temperature of the test environment and obtain the results of various performance tests at different ambient temperatures. During the operation of the refrigeration equipment, due to the action of internal heating devices such as the condenser, heat radiation will be generated, which will affect the accuracy of the temperature sensor in detecting the ambient temperature.

[0003] In the related art, an isolation device such as an isolation plate is added to the test platform, and the temperature sensor is separated from the refrigeration equipment by the isolation plate to reduce the impact of heat radiation.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] Adding an isolation plate can reduce the impact of the refrigeration equipment on the thermal radiation of the temperature sensor, but the positional relationship between the temperature sensor, the isolation plate and the refrigeration equipment will also affect the temperature test results.

[0006] GB / T8059-2016 Refrigeration Appliances for Household and Similar Purposes stipulates that the ambient temperature sensor should be 0.3m±0.1m away from the side of the appliance, and the gap between the ambient temperature sensor and any partition or fixture should be at least 25mm. However, the relevant technology lacks the design for precise adjustment of the temperature sensor and the refrigeration equipment and isolation board, so the position of the temperature sensor cannot be accurately set.

[0007] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0039] GB / T8059-2016 Household and Similar Purpose Refrigeration Appliances 7.4.3 and 7.4.4 have relevant provisions for the performance test platform of refrigeration equipment and other appliances. If the test sample has a condenser with fan forced circulation, it should be protected (if applicable) to ensure that the heat dissipation of the condenser does not directly affect the adjacent samples being tested. The protective plate should be at least 0.3m away from the side of the appliance. The ambient temperature sensor should be on both sides of the appliance, and the gap from the side of the appliance is 0.3m±0.1m, and the gap between the ambient temperature sensor and any partition or fixture is at least 25mm.

[0040] In the related art, an isolation plate is set on the side of the refrigeration equipment near the condenser in the test platform, and the temperature sensor is separated from the refrigeration equipment by the isolation plate to reduce the influence of heat radiation. However, the gap distance between the ambient temperature sensor and the refrigeration equipment and the isolation plate is not accurately adjusted to affect the test effect of the ambient temperature sensor.

[0041] The embodiments of the present disclosure provide a sensor adjustment device for a refrigeration equipment performance test system and a refrigeration equipment performance test system, so as to precisely adjust the gap between the sensor and the isolation plate and the refrigeration equipment, so as to accurately locate the sensor.

[0042] Combination Figure 1-4 As shown, according to a first aspect of an embodiment of the present disclosure, a sensor adjustment device for a refrigeration equipment performance testing system is provided.

[0043] Optionally, combined Figure 1 and Figure 2 As shown, the sensor adjustment device for the refrigeration equipment performance test system includes a first adjustment rod 30, a second adjustment rod 40, a sensor 20 and an isolation plate 50. The first adjustment rod 30 is horizontally arranged, and the extension line of the first adjustment rod 30 can intersect with the refrigeration equipment 10 to be tested, and is provided with a first scale 31; the first adjustment rod 30 includes a first end 32, and the first end 32 is used to abut against the refrigeration equipment 10 to be tested during the test; the second adjustment rod 40 is connected to the first adjustment rod 30 to support the first adjustment rod 30, so that the first adjustment rod 30 is horizontally arranged; and the first adjustment rod 30 can move in the horizontal direction relative to the second adjustment rod 40; the sensor 20 is suspended on the first adjustment rod 30; the isolation plate 50 is arranged The second adjustment rod 40 and the isolation plate 50 are located between the sensor 20 and the first end 32 of the first adjustment rod 30; during the test, the hanging position of the sensor 20 is limited so that the horizontal distance between the sensor 20 and the first end 32 of the first adjustment rod 30 is a preset test distance, the relative position of the first adjustment rod 30 and the second adjustment rod 40 is adjusted so that the isolation plate 50 contacts the sensor 20, and the first end 32 of the first adjustment rod 30 abuts against the refrigeration equipment 10 to be tested, so that the distance between the sensor 20 and the refrigeration equipment 10 to be tested is the preset test distance; the relative position of the first adjustment rod 30 and the second adjustment rod 40 is adjusted so that the sensor 20 is separated from the isolation plate 50, so as to adjust the gap distance between the sensor 20 and the isolation plate 50.

[0044] The first adjustment rod 30 is arranged horizontally, and the extension line of the first adjustment rod 30 intersects with the refrigeration device 10 to be tested, that is, the first adjustment rod 30 is perpendicular to the side wall of the refrigeration device 10 to be tested, that is, the first scale 31 is perpendicular to the refrigeration device 10 to be tested. In this way, the distance between the sensor 20 and the refrigeration device 10 and the distance between the sensor 20 and the isolation plate 50 can be accurately adjusted according to the first scale 31.

[0045] Optionally, the isolation plate 50 is connected to the second adjustment rod 40 , and the isolation plate 50 is disposed on a side of the second adjustment rod 40 away from the refrigeration device 10 , and is parallel to the refrigeration device 10 to be tested and the second adjustment rod 40 .

[0046] Optionally, the isolation board 50 is a board with a temperature insulation effect. Exemplarily, the isolation board 50 is a painted wooden board or plastic board.

[0047] It is understandable that the relative positions of the first adjustment rod 30 and the second adjustment rod 40 can also be adjusted first, so that the distance between the second adjustment rod 40 and the first end 32 of the first adjustment rod 30 is the preset test distance. The isolation plate 50 is arranged on the second adjustment rod 40, so that the distance between the isolation plate 50 and the refrigeration device 10 to be tested also meets the preset test distance, and the sensor 20 is suspended on the first adjustment rod 30, and the sensor 20 contacts the isolation plate 50, so that the distance between the sensor 20 and the refrigeration device 10 to be tested meets the preset test distance.

[0048] For example, the width of the second adjustment rod 40 is 0.01 m, and the thickness of the isolation plate 50 is 0.05 m. According to the national standard, the preset test distance is 0.3 m±0.1 m.

[0049] When the distance between the second adjustment rod 40 and the refrigeration device 10 to be tested is adjusted to 0.3m by the first scale 31, the distance between the isolation plate 50 and the refrigeration device 10 to be tested is the distance between the second adjustment rod 40 and the refrigeration device 10 to be tested plus the width of the second adjustment rod 40, that is, 0.31m, and the distance between the sensor 20 and the refrigeration device 10 to be tested is 0.31m plus the thickness of the isolation plate 50, that is, 0.36m, so that the distance between the sensor 20 and the refrigeration device 10 to be tested meets the standard requirement of 0.3m±0.1m specified in GB / T8059-2016. Thereby, the purpose of accurately adjusting the distance between the sensor 20 and the refrigeration device 10 to be tested is achieved.

[0050] After adjusting the distance between the sensor 20 and the refrigeration equipment 10 to meet the national standard, the relative positions of the first adjustment rod 30 and the second adjustment rod 40 are adjusted to separate the sensor 20 from the isolation plate 50 and to make the distance between the sensor 20 and the isolation plate 50 meet the national standard.

[0051] The sensor 20 can be separated from the isolation plate 50 by moving the first adjustment rod 30 in a horizontal direction away from the refrigeration device 10 to be tested. Since the sensor 20 is in contact with the isolation plate 50 when adjusting the distance between the sensor 20 and the refrigeration device 10 to be tested, and the sensor 20 is suspended from the first adjustment rod 30, when the first adjustment rod 30 is moved, the sensor 20 will follow the first adjustment rod 30, thereby adjusting the distance between the sensor 20 and the isolation plate 50 according to the first scale 31.

[0052] The method of separating the sensor 20 from the isolation plate 50 also includes moving the second adjustment rod 40 in a direction toward the refrigeration device 10 to be tested, so that the isolation plate 50 and the sensor 20 are separated.

[0053] GB / T8059-2016 stipulates that the gap between the sensor 20 and the isolation plate 50 is at least 25 mm.

[0054] Exemplarily, the adjustment method is, after the distance between the sensor 20 and the refrigeration equipment 10 to be tested is adjusted to 0.36m, the first adjustment rod 30 is moved horizontally away from the refrigeration equipment 10 to be tested, and the moving distance is 25mm. At this time, the sensor 20 follows the first adjustment rod 30 and moves 25mm away from the isolation plate 50, thereby making the distance between the sensor 20 and the isolation plate 50 meet the national standard requirements.

[0055] Because the sensor 20 follows the first adjustment rod 30 and moves 25 mm away from the refrigeration device 10 to be tested, the distance between the sensor 20 and the refrigeration device 10 to be tested also changes, that is, the distance increases by 25 mm. At this time, the distance between the sensor 20 and the refrigeration device 10 to be tested is 0.36 m + 25 mm, that is, 0.385 m, which meets the national standard requirements.

[0056] Although the position of the sensor 20 is adjusted twice, first the distance between the sensor 20 and the refrigeration device 10 to be tested is adjusted, and then the distance between the sensor 20 and the isolation plate 50 is adjusted. When the distance between the sensor 20 and the isolation plate 50 is adjusted for the second time, the distance between the sensor 20 and the refrigeration device 10 to be tested will also change, but because the distance of the second position adjustment is very small, even if the distance between the sensor 20 and the refrigeration device 10 to be tested changes, it still meets the national standard requirements.

[0057] Optionally, combined Figure 3 As shown, the sensor adjustment device for the refrigeration equipment performance test system to be tested also includes a positioning sleeve 42, which is arranged at the end of the second adjustment rod 40 facing the first adjustment rod 30, and is sleeved on the first adjustment rod 30, so that the first adjustment rod 30 can move in the horizontal direction relative to the second adjustment rod 40 through the positioning sleeve 42.

[0058] By setting a positioning sleeve 42, the scale of the first scale 31 is fixed by the end of the positioning sleeve 42, and the distance between the second adjustment rod 40 and the refrigeration device 10 to be tested can be obtained by reading the position scale of the positioning sleeve 42, so as to facilitate accurate adjustment of the distance between the second adjustment rod 40 and the refrigeration device 10 to be tested, and to facilitate accurate adjustment of the distance between the sensor 20 and the isolation plate 50.

[0059] In addition, the positioning sleeve 42 is sleeved on the outer wall surface of the first adjustment rod 30 , so that the first adjustment rod 30 can move in the horizontal direction relative to the second adjustment rod 40 by means of the positioning sleeve 42 .

[0060] Optionally, the isolation plate 50 can move in the vertical direction relative to the second adjustment rod 40 , and the position of the sensor 20 in the vertical direction can be adjusted by adjusting the position of the isolation plate 50 in the vertical direction, wherein the sensor 20 and the isolation plate 50 are arranged correspondingly.

[0061] Exemplarily, the sensor 20 is disposed corresponding to the middle portion of the isolation plate 50 .

[0062] During the test, the relative position of the isolation plate 50 and the second adjustment rod 40 is adjusted so that the height of the middle of the isolation plate 50 is the preset height distance, and the sensor 20 is correspondingly arranged in the middle of the isolation plate 50 so that the height of the sensor 20 is the preset height distance.

[0063] GB / T8059-2016 also stipulates the height of the temperature sensor, that is, the height of the temperature sensor is 0.9±0.1m on the platform or the height of the measured device±0.1m, whichever is lower.

[0064] Since the existing refrigeration equipment 10 is usually relatively high, the height of the temperature sensor is usually set at 0.9±0.1 m above the platform.

[0065] The second adjustment rod 40 is vertically arranged on the test platform, and the isolation plate 50 can move in the vertical direction relative to the second adjustment rod 40. The height distance between the middle of the isolation plate 50 and the bottom of the test platform is adjusted to 0.9±0.1m. The sensor 20 is arranged corresponding to the middle of the isolation plate 50, so the height distance between the sensor 20 and the bottom of the test platform is 0.9±0.1m, thereby making the height of the sensor 20 also meet the national standard requirements.

[0066] Optionally, the second adjustment rod 40 is arranged along the vertical direction and is provided with a second scale 41 .

[0067] By vertically arranging the second adjustment rod 40 and providing the second scale 41 , the height of the middle portion of the isolation plate 50 is adjusted according to the second scale 41 , thereby facilitating accurate adjustment of the height of the sensor 20 .

[0068] Optionally, the sensor adjustment device for the refrigeration equipment performance testing system also includes a positioning block 43, which is sleeved on the second adjustment rod 40 and can move in a vertical direction relative to the second adjustment rod 40, and can be locked to the second adjustment rod 40 when moving to a preset height position; the isolation plate 50 is provided with a slot hole 51, and at least a portion of the positioning block 43 is embedded in the slot hole 51 to connect the isolation plate 50 with the second adjustment rod 40, and enable the isolation plate 50 to move relative to the second adjustment rod 40 through the positioning block 43 and be locked at a preset height position.

[0069] The isolation plate 50 is provided with a slot hole 51 , and the positioning block 43 is embedded in the slot hole 51 , so that the positioning block 43 can drive the isolation plate 50 to move when it moves relative to the second adjustment rod 40 .

[0070] In addition, the second adjustment rod 40 is provided with a second scale 41, and the positioning block 43 is sleeved on the second adjustment rod 40, so as to facilitate reading the scale position of the positioning block 43 on the second adjustment rod 40, thereby facilitating obtaining the dimensional distance of the isolation plate 50 along the height direction.

[0071] At a preset height, the positioning block 43 can lock the isolation plate 50 to the second adjustment rod 40 to prevent the isolation plate 50 from sliding.

[0072] Optionally, combined Figure 3 As shown, the sensor adjustment device for the refrigeration equipment performance test system further includes a locking member 60 , which is disposed on the positioning block 43 to lock the isolation plate 50 to the second adjustment rod 40 .

[0073] Optionally, the locking member 60 includes a fastening bolt, and the positioning block 43 and the second adjustment rod 40 are provided with bolt holes. After the height adjustment of the sensor 20 is completed, the fastening bolt is tightened to fix the positioning block 43 to the second adjustment rod 40, thereby fixing the isolation plate 50 to the second adjustment rod 40 to prevent the isolation plate 50 from sliding relative to the second adjustment rod 40.

[0074] Optionally, the slot 51 is provided in the middle of the isolation plate 50 .

[0075] The slot 51 is provided in the middle of the isolation plate 50, and the positioning block 43 is embedded in the slot 51 to mount the isolation plate 50 on the second adjustment rod 40. The slot 51 is provided in the middle to evenly distribute the gravity of the isolation plate 50 and prevent the isolation plate 50 from being deflected.

[0076] Optionally, a middle portion of the isolation plate 50 corresponds to the sensor 20 .

[0077] The sensor 20 is disposed corresponding to the slot 51 . By reading the position data of the positioning block 43 on the second scale 41 , the height position of the sensor 20 can be known, so as to facilitate adjustment of the height of the sensor 20 .

[0078] The sensor 20 is disposed corresponding to the middle of the isolation plate 20 through the slot 51 , so that the isolation plate 20 uniformly blocks the influence of heat radiation on the sensor 20 from all directions.

[0079] According to a second aspect of an embodiment of the present disclosure, a performance testing system for refrigeration equipment is provided.

[0080] Optionally, combined Figure 1-3As shown, the performance testing system for refrigeration equipment includes a sensor adjustment device for a refrigeration equipment performance testing system according to any one of the above embodiments, a first partition 70 and a second partition 80, the first partition 70 is arranged opposite to the isolation plate 50, and the isolation plate 50 is arranged between the first partition 70 and the refrigeration equipment 10 to be tested; the second partition 80 is perpendicular to the first partition 70, and defines a test space with the first partition 70; the sensor adjustment device is arranged in the test space.

[0081] Optionally, the first partition plate 70 and the second partition plate 80 are plates made of the same material or a different material from that of the isolation plate 50. Exemplarily, the first partition plate 70 and the second partition plate 80 are wooden boards painted with black paint.

[0082] The first partition 70 and the second partition 80 are provided to define a test space, and the sensor 20 is separated from the external environment to avoid the influence of the external environment temperature on the temperature in the test space and the influence on the test value of the sensor 20.

[0083] GB / T8059-2016 also stipulates the depth of the temperature sensor 20, that is, the depth is at least 0.3m.

[0084] The first partition 70 and the second partition 80 define a test space, the sensor 20 is arranged in the test space, the second partition 80 is arranged corresponding to the rear wall of the refrigeration device 10, and the depth of the sensor 20 is the distance between the sensor 20 and the second partition 80.

[0085] Optionally, the second partition plate 80 is perpendicular to the isolation plate 50 , so that the distance between the sensor 20 and the second partition plate 80 can be determined by adjusting the distance between the isolation plate 50 and the second partition plate 80 .

[0086] The second partition plate 80 is perpendicular to the isolation plate 50 , so as to facilitate measuring the distance between the second partition plate 80 and the isolation plate 50 , and to facilitate adjusting the depth of the sensor 20 .

[0087] Optionally, the second partition plate 80 abuts against a side wall of the isolation plate 50 .

[0088] Optionally, the isolation plate 50 includes a first side wall 52 and a second side wall 53, wherein the first side wall 52 is perpendicular to the second side wall 53, the first side wall 52 extends along the width direction of the isolation plate 50, and the second side wall 53 extends along the length direction of the isolation plate 50. The first side wall 52 abuts against the second partition plate 80, and the second side wall 53 is perpendicular to the second partition plate 80.

[0089] The sensor 20 is disposed at the middle portion of the isolation plate 50 . The distance between the sensor 20 and the second partition plate 80 can be obtained according to the length of the second side wall 53 , that is, the distance between the sensor 20 and the second partition plate 80 is half the length of the second side wall 53 .

[0090] For example, an isolation plate 50 with a length greater than 0.6 m is selected, and the sensor 20 is disposed in the middle of the isolation plate 50 . Then, the distance between the sensor 20 and the second partition 80 is greater than 0.3 m, which meets the national standard requirement that the depth of the sensor 20 is at least 0.3 m.

[0091] The method of using the sensor 20 adjustment device for the refrigeration equipment 10 performance test system is described as follows:

[0092] (1) Select an isolation board 50 with a length greater than 0.6 m, such as an isolation board 50 of 0.7 m×0.7 m, and install the isolation board 50 on the second adjustment rod 40 through the positioning block 43. The temperature sensor 20 is suspended on the first adjustment rod 30 and is arranged corresponding to the slot 51 in the middle of the isolation board 50. At this time, the temperature sensor 20 meets the national standard requirement of a depth greater than 0.3 m.

[0093] (2) The first adjustment rod 30 is connected to the second adjustment rod 40 through the positioning sleeve 42, and the first end 32 of the first adjustment rod 30 is in contact with the refrigeration device 10 to be tested. The relative positions of the first adjustment rod 30 and the second adjustment rod 40 are adjusted so that the sensor 20 is in contact with the isolation plate 50, and the distance between the sensor 20 and the refrigeration device 10 to be tested is adjusted to 0.3 m. This satisfies the national standard requirement that the gap between the sensor 20 and the refrigeration device 10 is 0.3 m ± 0.1 m.

[0094] (3) The first adjustment rod 30 is moved more than 25 mm in a direction away from the refrigeration equipment 10 to be tested, so that the first adjustment rod 30 drives the sensor 20 to move more than 25 mm in a direction away from the isolation plate 50. At this time, the national standard requirement that the gap between the sensor 20 and any partition or fixing device is at least 25 mm is met.

[0095] (4) Move the isolation plate 50 in the vertical direction and adjust the height of the positioning block 43 to 0.9 m according to the second scale 41. Since the sensor 20 is arranged corresponding to the slot 51, the height of the sensor 20 is also 0.9 m. At this time, the height of the temperature sensor 20 meets the national standard requirement of 0.9±0.1 m on the platform.
