[0007] In the present invention, the beneficial effects of the air source heat pump testing device are: Due to the setting of the test mechanism, the pump flow rate is adjusted, the change of the condenser outlet temperature with the water flow rate is tested, the pressure drop at the inlet and outlet of the condenser is monitored, and the water side resistance is evaluated. The insulation layer can maintain a stable environment inside the test box; Thanks to the push mechanism, when the push plate moves upward and pushes the pump into the simulation box, the rubber block fits tightly against the outside of the simulation box, effectively preventing the exchange of gases, liquids and other substances inside and outside the simulation box. The bottom of the push plate is provided with three through holes. The push plate driven by the hydraulic cylinder provides a strong and stable thrust, which can accurately send the heavy heat pump into the designated position inside the simulation box. Thanks to the winding mechanism, when the winding roller rotates, pipes 2, 3, and 5, which were originally wrapped around it, are released under their own gravity and possible external tension, enabling the deployment and laying of the pipes. This allows for the release of pipes of different diameters and lengths, achieving automatic release and deployment. When the heat pump is pushed into the test position, it is automatically released from the winding roller and stretched into place, eliminating the need for manual pipe routing, significantly improving efficiency, and reducing confusion. Due to the setting of the surrounding spraying mechanism, the nozzle can achieve 360-degree rotation through the continuous forward and reverse rotation of the mounting block, so that it can spray water mist or temperature-regulating medium to the surrounding environment in all directions, which can simulate the humidity or temperature of the air, and can evenly spray water mist or adjust the temperature in all directions inside the simulation space, which can avoid the situation where the humidity or temperature in some local areas is too high or too low. During the simulation process, the change of air humidity or temperature is more uniform and consistent; Due to the swing mechanism, the water source inside the humidifier enters the nozzle through the humidification pipe, hose and connecting pipe, and is finally sprayed out from the nozzle. The humidifier realizes the function of humidifying the simulated air source heat pump operating environment, and can cover a larger space area, making the humidity or temperature distribution in the simulated environment more uniform, achieving all-round and no-dead-angle coverage of the internal space of the simulation box, and the spraying medium is evenly dispersed; Due to the heat dissipation mechanism, during the operation of the test chamber, internal components generate heat, which is transferred to the heat sink fin stack through heat conduction. The heat sink fins have a large surface area and can quickly absorb and store heat. The two fan blades blow air through the gaps between the heat sink fins. According to the principle of thermal convection, the air will carry away the heat on the heat sink fins during the flow process and bring the heat out of the test chamber, thereby achieving the purpose of lowering the internal temperature of the test chamber. The strong airflow formed by the dual fans flows through the fins, which can quickly and efficiently dissipate the heat generated in the test chamber, preventing the internal environment from overheating, ensuring the accuracy of temperature and humidity simulation and the safe operation of the equipment.

[0008] The present invention can evenly control the humidity around the heat pump, avoiding uneven humidity distribution in local areas. During the spraying process, the compressor and the outside of the evaporator can be protected, thus avoiding damage to core components and forced replacement, thereby improving the use effect.

[0022] In the present invention, when in use, the three sealed doors 2 are opened, water can be added to the storage box 5, and water is added to the humidification box 6 at the same time, and the pump 17 is placed in the test chamber. The test box 1 and the sealed door 2 cooperate with each other to form a sealed space to isolate the external environment. When the pump 17 needs to be tested, the device simulates the working cycle of the heat pump 17 through the four major components of the compressor 13, the condenser 14, the expansion valve, and the evaporator 16: compressor 13 → condenser 14 → expansion valve → pump 17 → evaporator 16 → compressor 13; compressor 13 → condenser 14 → expansion valve → cooling tower 15 → pump 17 → condenser 14 → compressor 13; adjust the flow rate of the pump 17, test the change of the outlet temperature of the condenser 14 with the water flow rate, and monitor the temperature of the condenser 14. The inlet and outlet pressure drops, evaluate the water side resistance, and the insulation layer can keep the environment inside the test box 1 stable. When the pump 17 needs to be pushed into the simulation box 8, by starting the hydraulic cylinder 18, its output shaft pushes the push plate 19 to move upward. Since the push plate 19 is flush with the bottom of the simulation box 8, the pump 17 can be pushed into the simulation box 8 smoothly and smoothly. During the pushing process, the push plate 19 serves as a stable support platform to ensure that the pump 17 accurately enters the simulation box 8 in the horizontal direction, avoiding equipment damage or inaccurate installation problems caused by tilting or shaking during the pushing process.

In order to exchange materials, three through holes 2 are provided at the bottom of the push plate 19. At the same time, when the winding roller 22 needs to release pipe 2, pipe 3 and pipe 5, the upward movement of the push plate 19 will simultaneously drive the three racks 1 23 to move upward, the three gears 1 24 rotate on the three racks 1 23, the three racks 1 23 drive the three rotating rods 25 to rotate, the three rotating rods 25 drive the three second sprockets 26 to rotate, and the three first chains 27 drive the three first sprockets 28 to rotate, the three first sprockets 28 drive the three rotating shafts 21 to rotate, and the three rotating shafts 21 drive the three winding rollers 22 to rotate. When the winding roller 22 rotates, pipes 2, pipes 3 and pipe 5 originally wound on the winding roller 22 will be released under the action of their own gravity and possible external tension. To realize the deployment and laying of pipelines, it is possible to release pipelines of different diameters and lengths. When the pump 17 is needed to simulate air humidity or temperature, by starting the driving motor 1 29, its output shaft drives the rotating rod 1 30 to rotate, the rotating rod 1 30 drives the mounting block 31 to rotate, the mounting block 31 drives the rotating rod 2 32 to rotate, the rotating rod 2 32 drives the gear 2 33 to move, the gear 2 33 moves on the circular rack 34, rotating while moving, and at the same time drives the installation box 50 and the nozzle 54 installed on the installation box 50 to rotate back and forth. By continuously rotating the mounting block 31 forward and reversely, the nozzle 54 can achieve 360-degree rotation, so that it can spray water mist or temperature-regulating medium to the surrounding environment in all directions, which can simulate the humidity or temperature of the air.And it can evenly spray water mist or adjust the temperature in all directions inside the simulation space, and can avoid the situation where the humidity or temperature in a local area is too high or too low. During the simulation process, the change of air humidity or temperature is made more uniform. At the same time, when it is necessary to swing the surrounding spraying mechanism, the first bevel gear 36 is driven to rotate by the rotating rod 2 32, the first bevel gear 36 drives the second bevel gear 37 to rotate, the second bevel gear 37 drives the rotating shaft 1 38 to rotate, the rotating shaft 1 38 drives the third sprocket 39 to rotate, and the fourth sprocket 41 is driven to rotate by the second chain 40, the fourth sprocket 41 drives the rotating shaft 2 42 to rotate, and the rotating shaft 2 42 drives the third The bevel gear 43 rotates, the third bevel gear 43 drives the fourth bevel gear 44 to rotate, the fourth bevel gear 44 drives the rotating shaft 3 45 to rotate, the rotating shaft 3 45 drives the half gear 1 46 to rotate, and the half gear 1 46 will drive the rack 2 47 to move upward during the rotation, and the rack 2 47 will simultaneously drive the rack 3 49 to move upward. When it moves to a certain extent, it will simultaneously drive the spring plate 48 to rebound, and the upward movement of the rack 3 49 will drive the half gear 2 51 to rotate, and the half gear 2 51 drives the rotating shaft 4 52 to rotate, and the rotating shaft 4 52 drives the mounting seat 53 to swing, and the mounting seat 53 is connected to the nozzle 54, thereby driving the nozzle 54 to swing. During the 360-degree rotation, the spraying range of the nozzle 54 is made wider and more uniform. The water source inside the humidifying box 6 enters the nozzle 54 through the humidifying pipe 57, the hose 56 and the connecting pipe 55, and is finally sprayed out from the nozzle 54. The humidifying box 6 realizes the function of humidifying the use environment of the simulated air source heat pump 17, and can cover a larger spatial area, so that the humidity or temperature distribution in the simulated environment is more uniform. The storage box 5 can store test water. The test cavity is an existing test equipment with detection structures such as a circulating pump 17 and a temperature sensor. When the interior of the test box 1 needs to dissipate heat, the output shaft of the driving motor 3 58 drives the rotating column 62 to rotate, and the rotating column 62 drives the fifth sprocket 59 to rotate, which drives the third chain 60 to drive the sixth sprocket 61 to rotate, and the sixth sprocket 61 drives the rotating column to rotate. The rotating column and the rotating column 62 drive the two fifth bevel gears 63 to rotate, the two fifth bevel gears 63 drive the two sixth bevel gears 64 to rotate, the two sixth bevel gears 64 drive the two heat dissipation rods 65 to rotate, and the two heat dissipation rods 65 drive the two fan blades 66 to blow air. The rotation of the fan blades 66 will form air flow inside the test box 1, generating wind force. During the operation of the test box 1, the internal components will generate heat, which will be transferred to the heat dissipation fins 67 stack by heat conduction. The heat dissipation fins 67 have a large surface area and can quickly absorb and store heat. The two fan blades 66 blow air through the gaps between the heat dissipation fins 67. According to the principle of thermal convection, the air will take away the heat on the heat dissipation fins 67 during the flow process and bring the heat out of the test box 1, thereby achieving the purpose of reducing the internal temperature of the test box 1.
