Description

TECHNICAL FIELD

[0001] The utility model relates to a granary temperature control device, especially relates to a granary low temperature circulation five side temperature control device and belongs to the field of warehousing. BACKGROUND

[0002] The granary is mainly used for storing grain, and when the grain generates heat, it is easy to breed insects and deteriorate, so it is necessary to keep the internal temperature of the granary constant. The existing way is to cover the inner wall of the granary with polyurethane insulation board or PEF foaming insulation board, which plays a heat insulation and heat preservation role through the insulation board. However, in the high-temperature environment in summer, the sunlight will still conduct a certain temperature to the inside of the granary when it shines on the wall of the granary, resulting in an increase in the temperature inside the granary and poor heat insulation and heat preservation effect. Therefore, people will set up multiple warehouse special air conditioners outside. The air outlet of the warehouse special air conditioner communicates with the inside of the granary, and the cold air blown out by the warehouse special air conditioner makes the inside of the granary reach the set temperature. However, due to the large size of the granary, the use of the warehouse special air conditioner to cool the entire granary consumes a lot of energy, increases the storage cost, and the cooling effect of the cold air blown out on the four sides of the granary is poor. After the outer wall of the granary is directly irradiated by the sun, the local temperature of the outer wall of the granary will still be high. Therefore, the present inventor has applied for a Chinese utility model patent 202121511979.0 with the patent name of "Granary inner side wall low temperature circulation heat insulation and heat preservation device". An air inlet and an air outlet are formed on the wall of the granary, a second warehouse special air conditioner is arranged on the outer wall of the granary, the outlet of the second warehouse special air conditioner is connected to an upper circulation pipeline, the other end of the upper circulation pipeline is connected to the air inlet, the inlet of the second warehouse special air conditioner is connected to a lower circulation pipeline, the other end of the lower circulation pipeline is connected to the air outlet, a PS extruded insulation board is arranged on the inner wall of the granary, two or more vertical air passage branch grooves are formed on the other side of the PS extruded insulation board, a layer of polyurethane insulation board is arranged on the outer wall of the other side of the PS extruded insulation board, the upper end of the air passage branch groove is connected to an air inlet main pipe, the air inlet main pipe communicates with the air inlet, the lower end of the air passage branch groove is connected to an air outlet main pipe, and the air outlet main pipe communicates with the air outlet. The structure has the following disadvantages: each air passage branch groove is an independent groove, the upper end of each air passage branch groove is connected to the air inlet main pipe, the lower end of each air passage branch groove is connected to the air outlet main pipe, the cold air blown out by the second warehouse special air conditioner enters the air inlet main pipe through the upper circulation pipeline and the air inlet, and then is transported to each air passage branch groove from the air inlet main pipe. The cold air is directly transported downward from the air passage branch groove to the air outlet main pipe, and the cold air does not circulate in the air passage branch groove. On the one hand, the cold air quickly passes through the air passage branch groove, which consumes more energy. On the other hand, since the air inlet is located at the middle position of the air inlet main pipe, the cold air transported by the air passage branch grooves located at the middle position will be more, while the cold air transported by the air passage branch grooves located at both sides will be less. This will result in temperature difference and poor cooling effect of the grain at the sides. In order to ensure the cooling effect, the power of the air conditioner needs to be increased, which increases the overall energy consumption. SUMMARY

[0003] The utility model discloses a low-temperature circulation five-side temperature control device for granary which has the advantages of uniform temperature in each part, high cold air recycling rate, low energy consumption, better heat insulation performance, simple structure and convenient installation.
