Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a special fumigation-proof speed-adjusting and temperature-controlling air conditioning unit for a granary. Background Art

[0002] The main functions of a granary are to store grain, maintain grain quality and prevent grain spoilage. In order to achieve these functions, the granary needs to provide suitable environmental conditions, such as controlling temperature, humidity and ventilation. Therefore, granary air conditioning has become one of the key equipment to ensure safe grain storage. However, during the use of granaries, it is often necessary to fumigate the granaries, and the phosphine gas produced during the fumigation process can easily cause damage to the internal components of the air conditioner.

[0003] In the prior art, some granary-specific air conditioners spray anti-corrosion coatings on the evaporators or use evaporators made of aluminum alloy in order to prevent the influence of fumigation on the air conditioners; for example, the utility model patent with the authorization announcement number CN219108241U discloses a granary-specific air-conditioning unit, which includes an air-conditioning main unit and a piping system, wherein an air outlet box includes an air inlet connected to the main unit air outlet, a first air outlet for cooling the air above the grain pile in the granary, a second air outlet for cooling the inside of the grain pile and a reversing device for adjusting the air volume of the first air outlet and the second air outlet; the evaporator is an anti-corrosion evaporator; the evaporator is made of aluminum alloy.

[0004] Although the granary-specific air-conditioning unit can prevent phosphine fumigation corrosion by anti-corrosion treatment of the evaporator, there are still problems in the actual use of the device: during the fumigation of the granary, the phosphine gas and the like generated can easily penetrate into the interior of the air-conditioning unit through various gaps on the air-conditioning unit, and it is not enough to only protect the evaporator of the indoor unit. Phosphine gas and the like can damage various components inside the indoor unit, which will seriously shorten the service life of the indoor unit in the long run. In view of this, we propose a granary-specific anti-fumigation speed-controlled temperature-controlled air-conditioning unit. Utility Model Content

[0032] In this embodiment, the cross-section of the protective cover 33 is L-shaped, and the protective cover 33 is made of aluminum alloy. This design is conducive to the protective cover 33 covering the outside of the air conditioner 32 to protect the air conditioner 32, and the aluminum alloy material has the advantage of corrosion resistance and can be suitable for the environment in the granary.

[0033] In this embodiment, a second sealing strip 312 is installed at the bottom of the top plate 31, a first sealing strip 303 is fixed to the front end surface of the fixing seat 30, and the second sealing strip 312 and the first sealing strip 303 are both in contact with the inner wall of the protective cover 33.
