Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, and specifically relates to a refrigerant pump air intake regulating device. Background Technology

[0002] Freon pump air conditioning technology originated from the improvement and innovation of traditional air conditioning refrigeration technology. With the advancement of science and technology and the improvement of environmental awareness, people began to seek more efficient, energy-saving and environmentally friendly refrigeration methods. Freon pump air conditioning technology came into being. It combines evaporation and condensation technology and Freon refrigerant, achieving a significant improvement in refrigeration effect and a significant reduction in energy consumption. Freon pump air conditioners are equipped with fans to introduce air into the air conditioning cabinet.

[0003] For example, Chinese patent CN221347240U discloses an air conditioning refrigerant pump. This air conditioning refrigerant pump includes a housing containing a fan, with a condenser on one side of the fan; it also includes a pump body and a control structure connected to a main pipeline. The control structure includes a cylinder connected to the main pipeline, a piston slidably and sealed within the cylinder, a first spring on the right side of the piston with its two ends connected to the piston and the cylinder respectively, a sliding rod fixedly mounted on the right side of the piston, one end of the sliding rod extending outside the cylinder and fixedly mounted with a terminal block, a terminal ring slidably mounted on the right side of the cylinder, and a second spring between the terminal ring and the cylinder.

[0004] The aforementioned patent addresses the problem of excessive refrigerant pressure in the pipes leading to pipe bursts due to an improper allocation of the compressor and refrigerant pump ratio. However, some shortcomings remain that require improvement. Specifically, the air inlet of the device cannot be adjusted, and the airflow into the device cannot be adjusted according to the outdoor temperature. When the outside temperature drops sharply and remains low, if cold air continues to be drawn in at a high flow rate, the temperature difference between the evaporator and the outdoor air will decrease, meaning less heat will be absorbed from the air. To maintain the cooling effect, the evaporator needs to consume more energy to lower its internal temperature to increase the temperature difference and continue absorbing heat from the air, increasing the evaporator's operating load and affecting the cooling efficiency and lifespan of the air conditioning system.

Detailed Implementation

[0021] Example

[0022] refer to Figures 1 to 4This embodiment of a refrigerant pump air conditioner air intake regulating device includes a cabinet 1. A fan 2 is fixedly connected to one side of the interior of the cabinet 1. A condenser 3 is located inside the cabinet 1 on one side of the fan 2. A pump body 4 is located inside the cabinet 1 on one side of the condenser 3. A main pipe 5 is installed on one side of the pump body 4. An air inlet 6 is opened on the cabinet 1 on one side of the fan 2. An adjusting plate 7 is rotatably connected inside the air inlet 6. A temperature and humidity sensor 14 is installed on the side of the cabinet 1 near the air inlet 6. A motor 8 is fixedly connected to the top of the cabinet 1. A first transmission assembly 9 is located inside the cabinet 1 on one side. A second transmission assembly 10 is located on one side of the first transmission assembly 9. A third transmission assembly 11 is located on one side of the adjusting plate 7. The first transmission assembly 9 is connected to the third transmission assembly 11 through the second transmission assembly 10.

[0023] refer to Figure 2-3 The first transmission assembly 9 includes a lead screw 91, which is fixedly connected to the output end of the motor 8. The lead screw 91 is rotatably connected to the inside side of the cabinet 1. A screw block 92 is threaded onto the outer surface of the lead screw 91. A transmission plate 93 is fixedly connected to one side of the screw block 92. The second transmission assembly 10 is located on one side of the transmission plate 93. A sliding groove 94 is provided on the inside side of the cabinet 1. The lead screw 91 is rotatably connected to the inside of the sliding groove 94. One side of the screw block 92 is slidably connected to the sliding groove 94. By setting the first transmission assembly 9, the motor 8 drives the lead screw 91 to rotate. After the lead screw 91 rotates, the screw block 92 on its surface moves under the action of the sliding groove 94. The transmission plate 93 is fixed on the screw block 92, thereby allowing the transmission plate 93 to move to provide transmission power for the second transmission assembly 10.

[0024] refer to Figure 3 The second transmission assembly 10 includes a rack 101, which is fixedly connected to the transmission plate 93. The rack 101 has three sets of racks. A gear 102 is meshed with one side of the rack 101, and a first rotating rod 103 is fixedly connected to one side of the gear 102. The first rotating rod 103 is rotatably connected inside the cabinet 1. By installing the rack 101 on the transmission plate 93, when the transmission plate 93 moves, it drives the multiple sets of racks 101 to move, so that the rack 101 pushes the gear 102. The gear 102 drives the first rotating rod 103 to rotate, thereby providing transmission power for the third transmission assembly 11.

[0025] refer to Figure 3The third transmission assembly 11 includes a first synchronous pulley 111, which is fixedly connected to the first transmission rod on the side away from the gear 102. The first synchronous pulley 111 is connected to a second synchronous pulley 113 via a synchronous belt 112. A second rotating rod 114 is fixedly connected to one side of the second synchronous pulley 113. One side of the adjusting plate 7 is fixedly connected to one side of the second rotating rod 114. By setting the third transmission assembly 11, the gear 102 drives the first synchronous pulley 111 to rotate. The first synchronous pulley 111 drives the second synchronous pulley 113 to rotate via the synchronous belt 112. The second synchronous pulley 113 drives the second rotating rod 114 to rotate. The second transmission rod drives the adjusting plate 7 to rotate within the air inlet 6, thereby adjusting the angle of the adjusting plate 7 and controlling the airflow. The design of the first synchronous pulley 111, the second synchronous pulley 113, and the synchronous belt 112 can also adopt a structure with toothed blocks.

[0026] refer to Figure 4 The cabinet 1 has an internal mounting groove 12. The second synchronous pulley 113 is rotatably connected to the inside of the mounting groove 12 via the second rotating rod 114. A through hole 13 is provided on one side of the mounting groove 12, and one side of the synchronous belt 112 passes through the through hole 13. The mounting groove 12 is provided for mounting the second synchronous pulley 113 and the second rotating rod 114. The through hole 13 is provided for mounting the synchronous belt 112, which facilitates the first synchronous pulley 111 to drive the second synchronous pulley 113 to rotate.

[0027] Operating principle and advantages: The temperature and humidity sensor 14 begins to monitor the outdoor temperature in real time. When the outdoor temperature drops below a preset threshold, the control system issues a command to drive the lead screw 91 in the first transmission assembly 9 to rotate using the motor 8. The screw block 92 on the lead screw 91 moves axially along the lead screw 91 under the guidance of the slide groove 94. The transmission plate 93 fixed on one side of the screw block 92 also moves accordingly. The movement of the transmission plate 93 drives the rack 101 in the second transmission assembly 10. The meshing of the rack 101 with the gear 102 causes the gear 102 to start rotating, which in turn drives the first rotating rod 103 to rotate. This power transmission process is further extended to the third transmission assembly 11, in which the rotation of the gear 102 drives the first synchronous pulley 1. 11. The first synchronous pulley 111 transmits power to the second synchronous pulley 113 via the synchronous belt 112. The rotation of the second synchronous pulley 113 drives the second rotating rod 114, ultimately achieving synchronous rotation of the adjusting plate 7 within the air inlet 6. The angle adjustment of the adjusting plate 7 directly affects the opening degree of the air inlet 6, thereby precisely controlling the airflow into the cabinet 1. Therefore, the system can automatically reduce the airflow when the outside temperature is low, thereby effectively reducing the load on the evaporator and the overall energy consumption. This helps to reduce unnecessary energy consumption, lower operating costs, reduce unnecessary high-load operation, and significantly extend the service life of the equipment.
