Energy-saving cold storage

Abstract

The invention discloses an energy-saving cold storage which comprises a cold storage body, a cooling assembly in the storage, a refrigeration assembly and a PLC control assembly, wherein the cooling assembly in the storage is installed on the cold storage body and communicated with the cold storage body and the refrigeration assembly. The PLC control assembly comprises at least one temperature detecting element, a control table and an electrical control cabinet, wherein the temperature detecting element is installed in the cold storage body and electrically connected with the control table, one end of the electrical control cabinet is electrically connected with the control table, and the other end of the electrical control cabinet is electrically connected with the refrigeration assembly. Comparing with the prior art, the energy-saving cold storage adopts the PLC control assembly to realize the real-time monitoring and automatic control of the cold storage. When the real-time temperature in the cold storage reaches the upper limit of the temperature value set by the PLC, the refrigeration assembly conducts refrigeration automatically. When the real-time temperature in the cold storage falls to the lower limit of the temperature value set by the PLC, the refrigeration assembly stops refrigeration without the need of artificial monitoring. Therefore, the energy-saving cold storage saves the manpower and the material resources, effectively reduces the energy consumption, and has the great significance of popularization.

Description

technical field [0001] The invention relates to a cold storage, in particular to an energy-saving cold storage, which belongs to the field of cold storage design. Background technique [0002] Cold storage, also known as cold storage, is a warehouse that uses cooling facilities to create suitable humidity and low temperature conditions, and is a place for processing and storing products. Cold storage reduces the incidence of pathogenic bacteria and fruit decay rate by lowering its internal temperature so that it will not deteriorate, and slows down the respiratory metabolism process of fruit through low temperature, so as to prevent decay, prolong the storage period, and get rid of the influence of climate , to regulate market supply. [0003] The ice cellar in northern China is the initial stage of cold storage. According to legend, the Beihai ice cellar in Beijing was built in the Ming Dynasty and has been in use for four to five hundred years. In the middle of the 19th...

Problems solved by technology

After visiting and researching various energy-saving cold storages around the life, the inventor found that many energy-saving cold storage operators or managers did not pay attention to the control and improvement of their refrigeration in the daily operation of energy-saving cold storage. A fixed value means refrigerating 24 hours a day. Although some operators realize that controlling the switch of the refrigerator according to a storage temperature range can keep the cold storage in a non-working state for a period of time and save energy, but due to energy-saving cold storage The control needs special supervision, which will undoubtedly increase labor costs. Some operators will eventually give up the supervision of cold storage because they are too busy or feel that controlling cold storage is too cumbersome and troublesome, and re-use 24-hour refrigeration, which will cause waste of energy consumption again
