Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration effect detection, and in particular to a refrigeration effect detection device for refrigeration equipment. Background Art

[0002] Air conditioners belong to refrigeration equipment. Air conditioners are air conditioners, which are composed of four parts: a refrigeration (heat) circulation system, an air circulation and ventilation system, an electrical control system, and a cabinet. They are small air conditioners used to keep the air in the conditioned space at a certain temperature, humidity, flow rate, cleanliness, and freshness. Hanging air conditioners: units used to provide space areas (generally closed) with air temperature changes. Their function is to adjust parameters such as the temperature, humidity, cleanliness, and air flow rate of the air in the room (or closed space or area) to meet the requirements of human comfort or process. Central air conditioners: air conditioning for large buildings, usually including multiple indoor and outdoor units, connected by a pipe system to achieve temperature control of the entire building. Air conditioners occupy an important position in the refrigeration equipment industry and are widely used in commercial, industrial, and civil fields. They are of great significance for improving the comfort of living and working environments.

[0003] The existing method of detecting the cooling effect of refrigeration equipment is mostly to use a handheld thermometer to detect the temperature at the indoor air outlet of the air conditioner. This detection method cannot guarantee the stability of the detected temperature, and holding the thermometer for too long will cause arm fatigue. The cold air blowing directly at the human body will also cause harm to the body. There is also a technical method to introduce cold air into a closed space, and use the built-in temperature detection equipment to detect the cold air temperature and wind speed to determine the cooling effect of the refrigeration equipment. However, when the refrigeration equipment is in use, the usage scenario may affect the cooling effect. Simply relying on the handheld thermometer to detect data is relatively single, and it is impossible to better judge the quality of the cooling effect. Summary of the invention

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention rotates the bidirectional screw, and the vertical frame cooperates with the bidirectional screw to slide along the second sliding frame, thereby adjusting the distance between the two corner frames 32 on the same side, and the folding bellows is folded longitudinally, so that the entire wrapping assembly can be adjusted according to the size of the air outlet of the refrigeration equipment, and the air outlet is completely covered to prevent the outflow of cold air and the entry of outside air.

[0017] 2. The present invention drives the vertical axis to rotate through a motor, and the mounting frame drives the three groups of detection cylinders to rotate.

[0018] 3. The present invention drives the shaft to rotate through the fan blade frame, the first bevel gear is meshed with the second bevel gear, and the second bevel gear drives the card block and the card frame to rotate, so that the rotating frame at the bottom of the card block rotates. Because the rotating frames in the two connecting tubes are connected by a transmission belt, they keep rotating synchronously, and the fan on its surface also rotates. Before the cold air is sent into the first detection cylinder, the heating rod in the second detection cylinder works to increase the temperature in the detection cylinder. In the process of heating, part of the heat enters the inside of the sealing cover through the conveying pipe through the rotation of the rotating frame and the fan, and at the same time, the heat and air are sent from the air holes into the inside of the wrapping layer through another group of rotating frames and fans. The outer wall of the first detection cylinder is made of a material with faster heat conduction. After the cold air enters the first detection cylinder, the hot air flows through the wrapping layer and is neutralized with the cold air in the first detection cylinder, thereby increasing the temperature in the first detection cylinder. In this state, the cooling effect of the refrigeration equipment when external hot air enters in a simulated indoor non-sealed environment is simulated.

[0019] 4. The present invention heats the second detection cylinder when the first detection cylinder is being detected, which, on the one hand, provides part of the heat for the first detection cylinder and, on the other hand, saves the intermediate waiting time for heating, thereby improving the overall detection efficiency.

[0020] 5. Compared with the prior art, the present invention uses three groups of reference detection detection tubes to simulate normal indoor environment, indoor window environment, and indoor high temperature environment respectively, and cooperates with the wrapping component to introduce cold air into the interior of the detection tube, and detects the time when the temperature in the tube approaches the predetermined temperature under different conditions.

[0035] In this embodiment, a rubber ring 312 is fixed at the bottom of the connection end of the hose 35 and the top plate 12, and the rubber ring 312 slides along the top plate 12, and sliders are fixed on both sides of the rubber ring 312. An annular groove 121 is provided on the top plate 12 corresponding to the moving path of the slider, and the slider of the rubber ring 312 slides along the annular groove 121. The detection chamber assembly 2 also includes a heat-insulating layer 27. The outer surfaces of the hose 35, the second detection cylinder 23 and the third detection cylinder 24 are all sleeved with the heat-insulating layer 27, and the second detection cylinder 23 is fixedly installed with a heating rod 28. A vertical shaft 11 is rotatably installed at the center of the base 1, and the mounting frame 21 is fixed on the vertical shaft 11. The top plate 12 is rotatably mounted on the top of the vertical shaft 11, a motor 14 is fixed inside the base 1, and the output end of the motor 14 is fixedly connected to the bottom of the vertical shaft 11, the vertical shaft 11 is driven to rotate by the motor 14, and the mounting frame 21 drives the three groups of detection cylinders to rotate, the detection cylinders can be replaced to receive the cold air sent by the refrigeration equipment, and then the test is carried out, and the alternation can avoid mutual interference, and at the same time, the second detection cylinder 23 can be heated and the first detection cylinder 22 can be given some heat. When the top plate 12 rotates, the connection end of the hose 35 and the top plate 12 slides along the annular groove 121 through the sliders on both sides of the rubber ring 312, and corresponds to the three connection ports 13 alternately, and no misalignment occurs.

[0036] In this embodiment, the transmission assembly 4 also includes a shaft 41, the hose 35 is rotatably mounted with the shaft 41 at the outer end corresponding to the fan blade frame 49, and the shaft 41 is fixedly connected to the rotating shaft of the fan blade frame 49, the outer end of the shaft 41 is fixed with a first bevel gear 42, and the bottom of the first bevel gear 42 is meshedly connected with a second bevel gear 44, a card frame 45 is fixed at the bottom of the second bevel gear 44, a card block 46 is slidably inserted inside the card frame 45, and the top of the rotating frame 47 is fixedly connected to the card block 46, the second bevel gear 44 is rotatably mounted on the shaft 41 through the connecting frame 43, the card block 46 and the card frame 45 have the same rotation arc as the connecting pipe 222, the base 1 is located on the surface of the bottom of the second detection cylinder 23 and is fixed with a bottom frame 26, and the bottom frame 2 6 contacts with the bottom of the second detection cylinder 23, a delivery pipe 5 is fixed on one side of the bottom frame 26, and the other end of the delivery pipe 5 is perpendicular to the top of another group of connecting pipes 222 of the sealing cover 221, and air holes 223 are equidistantly provided on the top and bottom of the wrapping layer 224, a fan 410 is fixedly installed on the surface of the rotating frame 47, and a transmission belt 48 is sleeved on the output shafts of the two groups of the rotating frames 47, and the transmission structure only acts on the first detection cylinder 22. When the first detection cylinder 22 rotates to the detection position, the air inlet pipe 29, the connecting port 13 and the outlet end of the hose 35 are on the same vertical line. Because the rotation arc of the card block 46, the card frame 45 and the first detection cylinder 22 is the same, the card block 46 will also be inserted into the card frame 45 at this time, and when the cold wind passes through the hose 35 When the cold air is sent to the inside of the first detection cylinder 22, the fan blade frame 49 rotates due to the flow of wind. A rotation sensor 311 is installed at the position of the fan blade frame 49 on the outside of the hose 35. The sensor is used to detect the wind speed. It is a prior art. The fan blade frame 49 drives the shaft 41 to rotate, and the first bevel gear 42 is meshed with the second bevel gear 44. The second bevel gear 44 drives the block 46 and the card frame 45 to rotate, so that the rotating frame 47 at the bottom of the block 46 rotates. Because the rotating frames 47 in the two connecting tubes 222 are connected by a transmission belt 48, they keep rotating synchronously, and the fan 410 on its surface also rotates. Before the cold air is sent to the first detection cylinder 22, the heating rod 28 in the second detection cylinder 23 works to increase the temperature in the detection cylinder. During the heating process In the embodiment, through the rotation of the rotating frame 47 and the fan 410, part of the heat enters the inside of the sealing cover 221 through the conveying pipe 5, and at the same time, the heat and air enter the inside of the wrapping layer 224 from the air hole 223 through another set of rotating frames 47 and fans 410. The outer wall of the first detection cylinder 22 is made of a material with fast heat conduction. After the cold air enters the first detection cylinder 22, the hot air flows through the wrapping layer 224 and neutralizes the cold air inside the first detection cylinder 22, thereby increasing the temperature inside the first detection cylinder 22. In this state, the cooling effect of the refrigeration equipment when external hot air enters in a simulated indoor non-sealed environment is simulated. The position of the conveying pipe 5 can avoid collision with the connecting pipe 222. The second detection cylinder 23 is heated when the first detection cylinder 22 is detected.On the one hand, it provides part of the heat for the first detection cylinder 22, and on the other hand, it saves the time for waiting for the temperature to rise, and improves the overall detection efficiency. The bottom of the detection cylinder is provided with an air outlet 25, the purpose of which is to keep the pressure in the detection cylinder stable. At the same time, the air outlet 223 has a small opening, which can keep the cold air for a period of time and avoid the rapid loss of cold air. The second detection cylinder 23 simulates the impact on the refrigeration effect when there is a device that can generate high temperature in the room. The temperature can be set by itself. When the detection cylinder reaches the predetermined temperature, cold air is sent into the detection area to neutralize the heat and cool down. The temperature sensor measures the time it takes to cool down to the predetermined temperature. The third detection cylinder 24 is a conventional detection cylinder, which can be understood as a blank test, simulating a relatively sealed indoor environment without a heat source, and simply detecting the refrigeration effect without considering other factors.

[0037] When using the device, the bidirectional screw rod 39 is rotated to adjust the distance between the two second sliding frames 36, and the folding corrugated layer 310 is folded horizontally. The bidirectional screw rod 38 is rotated, and the vertical frame 37 cooperates with the bidirectional screw rod 38 to slide along the second sliding frame 36 to adjust the distance between the two corner frames 32 on the same side. The folding bellows is folded longitudinally, so that the entire wrapping assembly 3 can be adjusted according to the size of the air outlet of the refrigeration equipment, and the air outlet is completely covered to prevent the outflow of cold air and the entry of outside air. The angle and height of the wrapping frame can be adjusted by the telescopic rod 33, which can be suitable for suspended refrigeration equipment, such as wall-mounted air conditioners, and can also be suitable for refrigeration equipment on the ground. The telescopic rod 33 can be locked by the locking bolt 34 to keep the wrapping frame wrapped in the air outlet position, and then alternately The cold air is sent into the first detection cylinder 22, the second detection cylinder 23 and the third detection cylinder 24, the vertical shaft 11 is driven to rotate by the motor 14, and the mounting frame 21 drives the three groups of detection cylinders to rotate, and the detection cylinders can be replaced to receive the cold air sent by the refrigeration equipment. When the first detection cylinder 22 rotates to the detection position, the air inlet pipe 29, the connecting port 13 and the outlet end of the hose 35 are on the same vertical line. Because the block 46 and the card frame 45 have the same rotation arc as the first detection cylinder 22, the block 46 will also be plugged into the card frame 45 at this time. When the cold air is sent to the first detection cylinder 22 through the hose 35, the fan blade frame 49 rotates due to the flow of wind, and the fan blade frame 49 drives the shaft rod 41 to rotate, and the first bevel gear 42 is meshed with the second bevel gear 44, and the second bevel gear 45 is meshed with the first bevel gear 42. The gear 44 drives the block 46 and the frame 45 to rotate, so that the rotating frame 47 at the bottom of the block 46 rotates. Because the rotating frames 47 in the two connecting tubes 222 are connected by the transmission belt 48, they keep rotating synchronously, and the fan 410 on its surface also rotates. Before the cold air is sent into the first detection cylinder 22, the heating rod 28 in the second detection cylinder 23 works to increase the temperature in the detection cylinder. In the process of heating, part of the heat enters the sealing cover 221 through the conveying pipe 5 through the rotation of the rotating frame 47 and the fan 410. At the same time, the heat and air are sent from the air hole 223 to the inside of the wrapping layer 224 through another set of rotating frames 47 and the fan 410. The outer wall of the first detection cylinder 22 is made of a material with faster heat conduction, and the cold air enters the first detection cylinder 2 2, the hot air flows through the wrapping layer 224 and neutralizes the cold air inside the first detection cylinder 22, thereby increasing the temperature inside the first detection cylinder 22. This state simulates the cooling effect of the refrigeration equipment when external hot air enters the indoor non-sealed environment. The position of the delivery pipe 5 can avoid collision with the connecting pipe 222. The second detection cylinder 23 is heated when the first detection cylinder 22 is detected. On the one hand, it provides part of the heat for the first detection cylinder 22, and on the other hand, it saves the time for waiting for heating in the middle, thereby improving the overall detection efficiency. The bottom of the detection cylinder is provided with an air outlet 25, the purpose of which is to keep the pressure in the detection cylinder stable. At the same time, the opening of the air outlet 223 is small, which can keep the cold air for a period of time and avoid the rapid loss of cold air.The second detection tube 23 simulates the impact on the refrigeration effect when there is a device that can generate high temperature in the room. The temperature can be set by yourself. When the predetermined temperature is reached in the detection tube, cold air is sent into the detection area to neutralize the heat and cool down. The temperature sensor measures the time it takes to cool down to the predetermined temperature. The third detection tube 24 is a conventional detection tube, which can be understood as a blank test. It simulates a relatively sealed indoor environment without a heat source. It simply detects the refrigeration effect without considering other factors. The refrigeration effect of the cold air sent by the refrigeration equipment is tested in different scenes. The wind speed is detected by the fan blade frame 49, and the time to reach the predetermined stability in the detection tube is detected by the temperature sensor inside the detection tube.
