Description

Technical Field

[0001] The utility model relates to the technical field of fruit and vegetable cold storages, in particular to a double-cold-source fruit and vegetable cold storage. Background Art

[0002] my country is a large agricultural country, and its annual output of fruits and vegetables ranks first in the world. However, compared with developed countries such as Europe and the United States, my country's post-harvest preservation technology for fruits and vegetables is seriously lagging behind, and a complete and independent cold chain for fruits and vegetables has not yet been formed. According to statistics from the Food and Agriculture Organization of the United Nations (FAO), my country's annual economic losses caused by post-harvest losses of fruits and vegetables are as high as 80 billion yuan, which seriously affects the national economy. Cold storage is the most important link in the fruit and vegetable cold chain system. Fruit and vegetable cold storage can effectively inhibit the aging of fruits and vegetables after harvest, reduce the physiological metabolic rate of fruits and vegetables, and help fruits and vegetables maintain their original freshness. At present, fruit and vegetable cold storages all use mechanical compression refrigeration. In order to ensure the low temperature environment in the cold storage, the heat load such as the respiratory heat of fruits and vegetables needs to be discharged from the storage in time. The refrigeration system of the cold storage needs to be kept open for a long time, and the system energy consumption is relatively large.

[0003] For example, application number CN201520300470.X. This utility model relates to a dual cold source cold storage for fruits and vegetables, including a storage body, a control system, a mechanical compression refrigeration system, a heat pipe refrigeration system and a humidifier; wherein, the mechanical compression refrigeration system is coupled with the heat pipe refrigeration system, and when the control system detects that the temperature outside the storage is lower than the temperature inside the storage, the heat pipe refrigeration system is turned on and the mechanical compression refrigeration system is turned off; when the temperature outside the storage is higher than the temperature inside the storage, the mechanical compression refrigeration system is turned on and the heat pipe refrigeration system is turned off. When the storage temperature is lower than the set temperature of the cold storage, the control system outputs a signal to turn off the mechanical compression refrigeration system and the heat pipe refrigeration system. The beneficial effects of this utility model are: by combining the application of mechanical compression refrigeration technology and natural cold source utilization technology, the cold source of the cold storage has the dual choice of mechanical refrigeration and natural cold source, which significantly reduces the operating energy consumption of the fruit and vegetable cold storage.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that the above equipment, when used, can solve the problem that the outdoor temperature is often lower than the refrigeration temperature of fruits and vegetables in the morning and evening periods of winter and transition seasons in northern regions. If the outdoor natural cold source can be used to adjust the temperature of the fruit and vegetable cold storage, the startup frequency and operation time of the mechanical compression refrigeration system of the cold storage can be reduced, which can significantly reduce the operation energy consumption of the cold storage. However, during use, in order to ensure the smooth opening or closing of the cold storage door, a certain activity space is usually reserved between the door and the threshold, and no sealing structure is provided, so that the reserved space will affect the sealing of the cold storage door when the cold storage door is closed.
