Research progress on cold store technology in the context of dual carbon

Abstract

With the rapid development of the social economy, people pay more attention to food safety, and the construction of cold stores in China has also developed rapidly. At the same time, the energy problem is increasingly serious at present, the “dual carbon” goal has made energy conservation and emission reduction become the focus of attention. This paper systematically reviews the low-carbon technology applied in cold store from two perspectives: refrigeration technology and cold storage technology. This paper introduces the development process of conventional mechanical refrigeration in cold stores and the current clean energy refrigeration technology at the forefront of cold store development. It summarizes the future development trend of conventional cold store refrigeration and the advantages and disadvantages of clean energy refrigeration. Then, combined with the dual carbon background, the advantages of cold storage technology are presented from the perspective of energy saving, cost reduction, and temperature stability improvement. It focuses on the phase change cold storage technology commonly used in cold stores and summarizes the advantages of phase change cold store at the present stage and the configuration principle of phase change materials in cold stores. Finally, the future development of cold store is prospected.
