Description

Technical Field

[0001] This application belongs to the field of refrigeration equipment manufacturing technology, specifically relating to an automatic cleaning device for central air conditioning surface coolers. Background Technology

[0002] In existing technologies, the central air conditioning surface cooler is the core component of the system's heat and moisture exchange. It achieves dehumidification and cooling in wet conditions by utilizing the temperature difference between the main air and the air at the outer boundary layer of the heat exchanger, as well as the water vapor partial pressure difference. It also has the functions of exchanging sensible and latent heat, resulting in stronger heat exchange capacity, and cooling in dry conditions with equal humidity. Its performance directly determines the air conditioning operating efficiency and energy consumption.

[0003] In existing technologies, after prolonged operation, central air conditioning condenser surfaces are prone to fouling, increasing thermal resistance and reducing heat exchange efficiency, necessitating regular cleaning. Current cleaning methods have significant shortcomings: traditional manual cleaning is inefficient, leaving areas such as fin gaps uncleaned, and poses safety risks and system interference; while mobile bases and lifting / rotating cleaning devices cover a wide area and are adaptable to complex fins, their complex structure and control result in poor versatility and high maintenance costs; intelligent control cleaning systems require no additional water source but can only remove surface dust, failing to thoroughly clean stubborn dirt. Furthermore, existing methods struggle to automate the mixing of cleaning agent spraying and water rinsing, easily wasting water or leaving residual cleaning agent that corrodes equipment.

[0004] Therefore, there is an urgent need to improve central air conditioning cleaning equipment to enhance cleaning efficiency, thoroughness, and versatility, reduce energy consumption and maintenance costs, ensure the heat exchange effect of the surface cooler, and improve the overall performance of the air conditioning system.

[0024] Combination such as Figures 1 to 7As shown, this technical solution is further illustrated: an automatic cleaning device for a central air conditioning unit includes an air conditioning body and a cooling coil disposed on the air conditioning body. It also includes a cleaning device 1 disposed on the air conditioning body and located on one side of the cooling coil. The cleaning device 1 includes a height adjustment mechanism 2 disposed on the air conditioning body, a spray mechanism 3 disposed on the height adjustment mechanism 2, and a liquid supply mechanism 4 disposed on the spray mechanism 3. The liquid supply mechanism 4 is used to supply cleaning agent to the spray mechanism 3, and the spray mechanism 3 is used to spray cleaning agent onto the cooling coil. The height adjustment mechanism 2 is used to adjust the height of the spray mechanism 3 relative to the bottom of the air conditioning body.

[0025] This application provides an automatic cleaning device for a central air conditioning unit's surface cooler. It includes an air conditioning unit, a surface cooler mounted on the air conditioning unit, and a cleaning device mounted on the air conditioning unit and located to one side of the surface cooler. The cleaning device includes a height adjustment mechanism mounted on the air conditioning unit, a spray mechanism mounted on the height adjustment mechanism, and a liquid supply mechanism mounted on the spray mechanism. The liquid supply mechanism supplies cleaning agent to the spray mechanism, and the spray mechanism sprays cleaning agent onto the surface cooler. The height adjustment mechanism adjusts the height of the spray mechanism relative to the bottom of the air conditioning unit. This device allows for flexible adjustment of the spray mechanism's height through the height adjustment mechanism, adapting to the cleaning needs of different areas of the surface cooler. It effectively and significantly improves the cleaning efficiency of the surface cooler, effectively removes dirt from the surface cooler, reduces thermal resistance, and improves heat exchange efficiency. It has the advantages of simple structure, low maintenance cost, guaranteed air conditioning operating efficiency, reduced air conditioning energy consumption, convenient operation, and ease of promotion and implementation.

[0026] In actual implementation, the cleaning device 1 is located on the windward side of the surface cooler, and the spray mechanism 3 is aimed at the area of ​​the surface cooler to be cleaned (fin area). The liquid supply mechanism 4 is pre-stored with sufficient cleaning agent and connected to the pipeline of the spray mechanism 3. Based on the height of the surface cooler and the distribution area of ​​the dirt, the height adjustment mechanism 2 is activated to drive the spray mechanism 3 to move vertically, adjusting it to the corresponding cleaning height to ensure that the spray range covers the target area of ​​the surface cooler. The liquid supply mechanism 4 is activated, and the cleaning agent is delivered to the spray mechanism 3 under pressure. The spray mechanism 3 then sprays the agent evenly onto the surface of the surface cooler and the gaps between the fins, using the chemical action of the cleaning agent and the impact force of the spray to decompose and peel off the dirt. The height of the spray mechanism 3 is gradually adjusted by the height adjustment mechanism 2 to ensure that the spray area fully covers the vertical direction of the surface cooler, completing the overall cleaning of the surface cooler. After cleaning, the liquid supply mechanism 4 and the height adjustment mechanism 2 are closed, completing a single cleaning cycle.

[0027] In this embodiment, the height adjustment mechanism 2 includes a vertical slide rail 20 on the air conditioner body, a sliding seat 21 on the vertical slide rail 20, and a driving member on the sliding seat 21. The driving member is used to drive the sliding seat 21 to slide along the length direction of the vertical slide rail 20, and the spray mechanism 3 is disposed on the sliding seat 21.

[0028] In actual implementation, the vertical slide rail 20 is fixed to the air conditioner body by bolts or welding. The slide rail is provided with a T-slot, and the sliding seat is matched and set in the T-slot. The spray mechanism 3 is fixed to the sliding seat 21 by flange or buckle. The driving component is an electric push rod. The output end of the driving component is connected to the sliding seat. The driving component is used to drive the sliding seat to slide along the length of the slide rail.

[0029] In this embodiment, the spraying mechanism 3 includes a spray pipe 30 disposed on the sliding seat 21, and a hose 31 with one end connected to the spray pipe 30 and the other end connected to the liquid supply mechanism 4.

[0030] In actual implementation, by setting up a hose, interference between the hose and the height adjustment mechanism can be avoided when the spraying mechanism moves along the length of the slide rail.

[0031] In this embodiment, the spray pipe 30 includes a horizontal pipe 300 disposed on the sliding seat 21, and a plurality of nozzles 301 spaced apart along the length of the horizontal pipe 300.

[0032] In this embodiment, the liquid supply mechanism 4 includes a liquid storage tank 40 disposed on the air conditioner body and a liquid supply pump 41 disposed on the liquid storage tank 40. The liquid storage tank 40 is used to contain cleaning agent, and the liquid supply pump 41 is used to transport the cleaning agent in the liquid storage tank 40 to the spray mechanism 3.

[0033] In this embodiment, the liquid supply mechanism 4 further includes an inlet pipe assembly 42 and an outlet pipe assembly 43 disposed on the liquid storage tank 40. The inlet pipe assembly 42 is used to deliver cleaning agent into the liquid storage tank 40, and the outlet pipe assembly 43 is used to discharge the cleaning agent from the liquid storage tank 40 into the liquid storage tank.

[0034] In this embodiment, the liquid supply mechanism 4 further includes a first liquid level sensor 44 disposed in the liquid storage tank 40, and a second liquid level sensor 48 disposed in the liquid storage tank 40 and located above the first liquid level sensor 44.

[0035] In actual implementation, the first liquid level sensor is a low liquid level sensor and the second liquid level sensor is a high liquid level sensor. By setting the first liquid level sensor and the second liquid level sensor, the liquid level information of the cleaning agent in the storage tank can be effectively monitored.

[0036] In this embodiment, the liquid storage tank 40 is provided with a partition 45, which divides the liquid storage tank 40 into a first liquid storage tank 46 and a second liquid storage tank 47. The first liquid storage tank 46 is used to contain the first cleaning agent, and the second liquid storage tank 47 is used to dissolve the second cleaning agent.

[0037] In actual implementation, the first cleaning agent is water, and the second cleaning agent is a surfactant.

[0038] In actual implementation, this application also includes a pressure sensor installed on the surface cooler. The pressure sensor includes a first pressure measuring port installed on the windward side of the surface cooler and a second pressure measuring port installed on the leeward side of the surface cooler. The first pressure measuring port is used to measure the inlet air pressure of the surface cooler, and the second pressure measuring port is used to measure the outlet air pressure of the surface cooler. By measuring the inlet air pressure and outlet air pressure of the surface cooler, it is possible to effectively determine whether the surface cooler is blocked.
