Description

Technical Field

[0001] The utility model relates to the technical field of grain bin air-conditioning units, in particular to a grain bin air-conditioning unit for grain surface cooling suitable for installation in a narrow passage. Background Art

[0002] Grain depots are characterized by large floor areas, strong particularity of guarantee equipment, and high operating costs. Due to the high original moisture content of grains, microorganisms in them will multiply in large numbers under suitable temperature conditions, causing the grains to easily generate heat. If the heat dissipation is not smooth, it is easy to cause the grains to age and turn yellow, and then become moldy and deteriorated.

[0003] For this reason, grain bins will use grain bin air-conditioning units to cool the grains to achieve safe storage of the grains. Grain bin air-conditioning units are divided into grain surface cooling grain bin air-conditioning units and grain pile cooling grain bin air-conditioning units.

A partition board is provided between the air permeation chamber and the air treatment chamber, the air treatment chamber communicates with the air supply chamber, a condensation module is installed in the air permeation chamber, an evaporator is installed in the air treatment chamber, and an air supply fan is installed in the air supply chamber.

However, this kind of grain surface cooling grain bin air-conditioning unit with the air permeation chamber, the air treatment chamber, and the air supply chamber side by side laterally inside the machine body requires a relatively large lateral installation space, and the heat dissipation air outlet direction of its condensation module is usually located in the front of the machine body, resulting in poor heat dissipation effect when the grain surface cooling grain bin air-conditioning unit is installed in a narrow passage.

[0025] The circulation module 15 is arranged in the ventilation chamber 101 and the air treatment chamber 103, connecting the condensation module 14 and the evaporator 12 to form a cooling circulation system.

One end of the supply air pipe 21 penetrating into the granary is arranged laterally opposite to one end of the return air pipe 22 penetrating into the granary.

[0027] Further, in this embodiment, a nozzle 211 is installed at one end of the supply air pipe 21 penetrating into the granary.

[0028] Further, in this embodiment, a filter screen 221 is installed at one end of the return air pipe 22 penetrating into the granary.

[0029] Further, in this embodiment, the condensation module 14 includes two condensers 141. Both condensers 141 are in a flat plate shape and are installed vertically and oppositely at the front end and the rear end inside the ventilation chamber 101. A duct opposite to the condensation fan 107 is reserved between the two condensers 141. By cooperating the condensation fan 107 with the condensers 141, forced heat exchange is achieved.

[0030] Further, in this embodiment, with reference to Figure 5 , the circulation module 15 includes an upper circulation pipeline group 151 connecting the output end of the evaporator 12 and the input end of the condensation module 14 and a lower circulation pipeline group 152 connecting the output end of the condensation module 14 and the input end of the evaporator 12.

[0037] It can be understood that the usage method of a grain surface cooling granary air conditioner unit suitable for narrow passage installation of the present utility model after being installed in a narrow passage is as follows: During the refrigeration cycle when sending air to the grain surface, the compressor 32 compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas. The high-temperature and high-pressure gas enters the condenser 141 and undergoes forced heat exchange through the condensing fan 107 to take away the heat. Among them, the lateral heat dissipation air outlet of the condensing fan 107 can form a better heat dissipation effect. Subsequently, the refrigerant enters the liquid receiver 33 and sequentially passes through the drying filter 34 and the sight glass 35, and is throttled by the expansion valve 36. The refrigerant becomes a low-temperature and low-pressure liquid and evaporates into a gas in the evaporator 12, absorbing the heat of the air passing through the evaporator 12 to cool the air. After the low-temperature and low-pressure refrigerant passes through the gas-liquid separator 31 and separates a small part of the refrigerant liquid, the refrigerant gas enters the compressor 32 for compression to complete a cycle.

[0038] In summary, for a grain surface cooling granary air conditioner unit suitable for narrow passage installation of the present utility model, through the cooperation between the air conditioner main unit 10 and the pipeline system 20, the air that needs to be cooled is input into the air conditioner main unit 10 from the return air duct 22. Driven by the air supply fan 13, the formed air flow is input from the air inlet 106, and after passing through the evaporator 12 for cooling, it is output from the air outlet 105 to the air supply duct 21, and is sent into the granary interior through the air supply duct 21 to cool the grain surface. And by laterally arranging the air supply chamber 102 and the air treatment chamber 103 side by side above the air permeable chamber 101 in the machine body 11, it requires less lateral installation space, and with the lateral heat dissipation air outlet of the condensing fan 107, the heat dissipation effect when installed in a narrow passage is effectively improved.
