Abstract

The invention discloses a method and device for determining optimized energy consumption of a refrigeration house, and particularly relates to the technical field of energy conservation of refrigeration houses. The method comprises the following steps that S1, temperature data are obtained; S2, the maximum temperature difference value and the minimum temperature difference value are determined; S3, the average value of the maximum temperature difference value and the minimum temperature difference value is calculated; S4, the maximum energy consumption and the minimum energy consumption are determined; and S5, the energy consumption of the refrigeration house is optimized. The invention further provides the device for optimizing the energy consumption of the refrigeration house. The deviceis composed of an optimization device host and an optimization control box. According to the method and device for determining the optimized energy consumption of the refrigeration house, the optimization device is used in cooperation with the method for determining the optimized energy consumption of the refrigeration house so that the temperature difference value between the internal environment and the external environment of the refrigeration house can be rapidly and accurately determined, the temperature difference value between the internal environment and the external environment of the refrigeration house under the minimum energy consumption is obtained through calculation, the temperature of the internal environment of the refrigeration house is adjusted according to the change of the temperature of the external environment of the refrigeration house, so that the temperature is kept under the temperature difference value of the temperature, and then the energy consumption ofthe refrigeration house can be effectively optimized; and in addition, the operation and control are simple, rapid and effective.

Description

technical field [0001] The invention relates to the technical field of cold storage energy saving, in particular to a determination method and device for optimizing energy consumption of a cold storage. Background technique [0002] Cold storage has always been an important part of the logistics industry. It is mainly used for constant temperature storage of semi-finished and finished products such as food, dairy products, meat, fruits and vegetables, and medicines. Logistics companies are very concerned about the energy consumption of cold storage, because in the use of cold storage, most of the economic consumption comes from the expenditure of electricity; [0003] The energy consumption of the cold storage is mainly affected by the temperature change in the cold storage. However, in the current application of cold storage, there are generally problems in the application of cold storage, such as poor insulation effect of cold storage construction materials, improper selec...
