Solar power semiconductor refrigeration temperature control freshness retaining box

Abstract

The invention discloses a solar power semiconductor refrigeration temperature control freshness retaining box, and relates to the field of freshness retaining boxes. The freshness retaining box adoptsa solar power module to carry out power supply work on the basis of the solar technology, energy saving and environment friendliness are achieved, a master control module achieves regulation of air pressure, temperature and humidity and the oxygen containing amount of the environment in the box through an air pressure detection control module, a temperature and humidity detection control module and an oxygen containing amount detection control module, meanwhile, in combination with the semiconductor refrigeration technology, the modules are high in integration, energy consumption is reduced,and the whole size of the freshness retaining box is reduced; the master control module is connected with a Bluetooth module, on the basis of the internet of things technology, remote monitoring and intelligent regulation of inner environment of the freshness retaining box can be achieved, and the freshness retaining box can prolong the guarantee period of fruits and vegetables in the box, ensurethe value of drugs in the period of validity, be suitable for logistics transportation and fresh storage of fresh fruits and vegetables and expensive medicines in a storage warehouse.

Description

technical field [0001] The invention relates to the field of fresh-keeping boxes, in particular to a semiconductor refrigeration temperature-controlled fresh-keeping box powered by solar energy. Background technique [0002] For a long time, the unsuitable post-harvest storage, transportation and fresh-keeping facilities and technologies have been the main reason for restricting the efficient circulation of fruits and vegetables. This has led to a post-harvest loss rate of 20% to 30% of fruits and vegetables in my country, and more than 142 million tons of agricultural products are rotted and lost every year. The value exceeds 100 billion yuan. On the other hand, in accordance with the requirements of the "Quality Management Standards for Pharmaceutical Operations", when enterprises operate refrigerated and frozen pharmaceuticals, they need to follow the storage requirements marked on the packaging of the pharmaceuticals in accordance with the storage requirements on the pack...

AI Technical Summary

Problems solved by technology

At present, fresh-keeping boxes are usually used to preserve fresh fruits and vegetables and valuable medicines, but the equipment of conventional fresh-keeping boxes is complicated, which makes the whole fresh-keeping box bulky, inconvenient to move, and high energy consumption, and the degree of intelligence is not high enough
