Research on Energy Consumption Evaluation Method and Energy Saving Operation Technology of Cold Storage

Abstract

There is not yet a recognized unified energy consumption assessment and grading method on cold storage. It is not conducive to cold storage operation energy-saving management. By establishing the heat balance model of the cold storage, the energy consumption composition of the cold storage is analyzed, and then the causal diagram analysis method is used to determine the influencing factors of the energy consumption of the cold storage, and the quantitative indicators to measure the energy consumption of the cold storage are proposed. Based on the classification of energy consumption assessment methods for cold storage, five typical energy consumption assessment methods for cold storage are compared and analyzed from five aspects of quantification, evaluation index, energy efficiency level, application scope and shortcomings. It is found that to establish an energy efficiency level identification evaluation standard for cold storage recognized by the public, two conditions must be met: the appropriate energy consumption assessment method considering the differentiation of cold storage; establishment of a large database of cold storage energy consumption information. Accordingly, the ways and measures for energy saving of cold storage are proposed.
