Solar Wind Auxiliary Temperature Control Cellar

Abstract

The invention relates to a solar energy wind-assisted temperature-control underground cave. The underground cave comprises a cave body which is situated below the surface. The all-around side walls and the roof of the cave body are provided with insulation wall layers and a storage room is intervally arranged in the underground cave. The storage room is made from waterproof air-permeable uninsulated material and the bottom of the storage rooms is provided with a support frame, the storage room is suspended in the middle of the cave body. Interlayer space is formed between the storage rooms and the underground cave. The inside of the interlayer space is provided with an ice machine. The power source of the ice machine is connectively arranged on the solar power system aboveground and the ice made by the ice machine fills in the interlayers. The top of the storage rooms is provided with an air intake, the inside of the air intake is provided with a fan and the middle part of the side wall of the storage room is provided with an air outlet. The fan takes in air from the air inlet on the top and exhausts air from the air outlets on the side walls. The surrounding of the storage rooms is airtight and uninsulated. The storage type of the fruits and vegetables solar energy wind-assisted temperature-control underground cave is hanging whole-underground structure; the walls are provided with interlayers; the natural cold sources are fully made use of; interlayers are used for ventilation, cold storage and ice storage. The solar energy and wind power are used for generating electricity to drive the ice machine. The air inside the underground cave is forcibly circulated through the fan, and thus mould proofing and fresh keeping of fruits and vegetables are achieved.

Description

technical field [0001] The invention belongs to the field of anti-mildew and fresh-keeping, in particular to a solar wind-assisted temperature-control cellar. Background technique [0002] Crypts are the most popular, longest-serving, and largest-storage fruit and vegetable facilities in Northeast, Northwest, North, Southwest, and Central China (parts) of China. At present, the total number of cellars in the country is about 20 million, and the total storage capacity is about 50 million tons, which is equivalent to 2-3 times the total storage capacity of cold storage and air-conditioning storage. During the national "Sixth Five-Year Plan" - "Twelfth Five-Year Plan" period, crypts were listed as national and provincial research and development projects to varying degrees, but there was a lack of system integration innovation and personalized promotion. With the improvement of people's living standards, traditional crypts have low facility standards, poor ventilation, and unc...

During the national "Sixth Five-Year Plan" - "Twelfth Five-Year Plan" period, crypts were listed as national and provincial R&D projects to varying degrees, but lacked system integration innovation and personalized promotion

With the improvement of people's living standards, traditional cellars have low facility standards, poor ventilation, and uncontrollable storage temperature. The freshness of fruits and vegetables in the later stage of storage is seriously affected, and they can no longer meet people's demand for fresh fruits and vegetables.

[0003] Existing crypts are dug 1-2 meters from the surface to the ground, surrounded by brick walls to obtain a square crypt, and the upper surface of the crypt is paved with a cover. Such a crypt has a simple structure and poor insulation effect. The invention provides a new type of cellar, which can self-circulate the cold source, ensure that the temperature of the cellar is moderately low, and does not require additional energy, and can circulate by itself
