Abstract
Description
Technical Field
[0001] The utility model relates to a dehumidification system with a circulating air duct. Background Art
[0002] As the country pays more and more attention to agriculture and provides more and more support, the requirements for high-precision constant temperature and humidity equipment in agriculture and other fields are becoming more and more numerous and higher.
[0003] Specific places such as cold storage generally adopt the method of refrigeration equipment + dehumidifier to solve the humidity problem. In recent years, the scope of using new equipment and technologies with refrigeration and dehumidification functions has become increasingly widespread. Due to its working principle, the temperature difference in the warehouse is large (the temperature difference reaches 8-10°C when the humidity is 45% in general situations), and the humidity difference is also large (typically, the humidity rises by about 5% within 1-2 minutes after shutdown, and the fluctuation is large).
[0004] Analysis of the reasons why the existing technology has the above shortcomings: In special constant temperature and humidity occasions such as cold storage, when refrigeration and dehumidification are used, the evaporator fan motor speed in the warehouse is relatively low due to the refrigeration and dehumidification principle; the refrigeration and dehumidification parameter perception is achieved through sensors, and the lower the temperature and humidity, the lower the wind speed, the smaller the affected range; coupled with factors such as the stacking of goods in the warehouse hindering air flow, the circulation range formed is limited, and the temperature and humidity are difficult to penetrate into every corner, resulting in uneven temperature and humidity in the warehouse, which has a greater negative impact on the storage of goods.
[0005] Therefore, it is necessary to design a new dehumidification system. Utility Model Content
[0006] The technical problem to be solved by the utility model is to provide a dehumidification system with a circulating air duct, which can effectively ensure the uniformity of humidity in the warehouse.
[0007] The technical solution of the utility model is as follows:
[0008] A dehumidification system with a circulating air duct comprises a dehumidifier and a circulating air duct; the dehumidifier is arranged in a warehouse, and the circulating air duct is arranged along the inner wall of the warehouse;
[0009] The side wall of the warehouse has a first interlayer, the top of the warehouse has a second interlayer, the side wall and the top plate of the warehouse are provided with air holes, the air holes are used to connect the first interlayer and the second interlayer with the middle cavity of the warehouse; the first interlayer is connected with the second interlayer; the first interlayer, the second interlayer and the air holes form the circulating air duct;
[0010] The utility model also comprises a fan, which is arranged in the first interlayer or the second interlayer, or the fan is arranged outside the air hole (not in the interlayer, but in the warehouse).
[0011] The number of the circulating air ducts is 2 or 4, and they are arranged relatively symmetrically (ie, arranged on the front and rear side walls, and / or on the left and right side walls).
[0012] A controller is also included; both the dehumidifier and the fan are controlled by the controller.
[0013] The air outlet of the dehumidifier is connected to the air duct.
[0014] The warehouse is a cold storage.
[0015] The dehumidifier is a refrigeration dehumidifier.
[0016] The refrigeration dehumidifier is installed on the top of the warehouse.
[0017] Beneficial effects:
[0018] The dehumidification system with circulating air duct of the utility model is equipped with one or more sets of internal circulating air duct systems in specific occasions such as cold storage, selects universal fans as power, and adopts top-in and bottom-out or bottom-in and top-out methods to make the air in the warehouse flow fully, greatly reduce the temperature and humidity dead corners in the warehouse, and effectively improve the uniformity of temperature and humidity in the warehouse.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
[0025] Example 1: Figure 1-3 The dehumidification system with a circulating air duct includes a dehumidifier 2 (specifically a refrigeration dehumidifier) and a circulating air duct; the dehumidifier is arranged in the warehouse, and the circulating air duct is arranged along the inner wall of the warehouse;
[0026] The side walls of the warehouse have a first interlayer 4, the top of the warehouse has a second interlayer 1, and the side walls and the top plate of the warehouse are provided with air holes 5, the air holes are used to connect the first interlayer and the second interlayer with the middle cavity of the warehouse (the upper air holes connect the first interlayer with the middle cavity of the warehouse, and the lower air holes connect the second interlayer with the middle cavity of the warehouse); the first interlayer is connected with the second interlayer; the first interlayer, the second interlayer and the air holes form the circulating air duct; the dehumidifier is arranged on the top of the warehouse.
[0027] The dehumidifier further comprises two fans 3, both of which are arranged in the second interlayer and on both sides of the air outlet of the dehumidifier.
[0028] The number of the circulating air ducts is 2 or 4, and they are relatively symmetrically arranged (i.e. arranged on the front and rear side walls, and / or arranged on the left and right side walls). [Or for irregular environments, more circulating air ducts are used.]
[0029] A controller is also included; both the dehumidifier and the fan are controlled by the controller.
[0030] The air outlet of the dehumidifier is connected to the air duct.
[0031] The warehouse is a cold storage.
[0032] After the refrigeration equipment and cooling equipment are started, one or more circulation fans in the warehouse are started synchronously to transport the air in the warehouse from the high (or low) place in the warehouse to different positions in the low (or high) place in the warehouse through the air duct; after the refrigeration and dehumidification equipment is shut down, the fan circulation system can choose to shut down synchronously, or choose to delay shutdown according to different requirements to ensure the uniformity of temperature and humidity in the warehouse.
[0033] Under the control of the controller, the refrigeration and dehumidification equipment and the fan can be stopped at the same time or with a delay, and other control circulation fan working modes can be achieved. Its function is to meet the requirements of temperature difference and humidity difference in occasions with different temperature and humidity requirements.
