As an important part of cold chain logistics, cold storage is also a key part of high power consumption. According to statistics, the annual electricity bill of China's cold storage exceeds 80 billion yuan. Therefore, making cold storage both energy-saving and energy-saving is not only related to the direct interests of enterprises, but also the social responsibility of promoting green and low-carbon development.
How to save electricity and energy in cold storage? We start from the following six aspects to effectively reduce the energy consumption and operating costs of cold storage, and improve the efficiency and quality of cold storage. Let's take a look!
1. Optimize from the design direction.
Reasonable cold storage design can save energy and reduce heat load and cooling capacity.
1. Choose the appropriate building form and structure.
According to the scale, use, geographical location and other factors of the cold storage, select the appropriate building form and structure, such as single or multi-storey, flat or inclined roof, frame or steel structure, etc., to reduce the external surface area and thermal bridging effect.
2. Choose the appropriate insulation material and thickness.
Thermal insulation materials are the key factors of thermal insulation performance and heat loss of cold storage, and suitable insulation materials and thicknesses should be selected according to the temperature, humidity, life and other factors of cold storage, such as polyurethane, extruded plastic board, rock wool, etc., and sealed and moisture-proof.
3. Choose the right refrigeration system.
The energy consumption of cold storage mainly comes from the refrigeration system. Reasonable selection of compressors and refrigerants, and setting appropriate temperature parameters, can ensure the stable operation of the system and achieve energy saving effect.
Second, optimize from the aspect of operation.
Cold storage should adopt a reasonable operation plan, which can effectively reduce energy consumption and operating costs.
1. Precise temperature control.
Zhongtai Xinhe cold storage energy-saving solution adopts advanced control equipment and procedures, which can reasonably set the temperature control range according to the nature, quantity, stacking method and other factors of the goods in the cold storage, so as to avoid too high or too low, so as to ensure the stability and consistency of the temperature in the cold storage.
2. Reasonably arrange the entry and exit and stacking of goods.
The entry and exit of goods and stacking will affect the air flow and temperature distribution in the cold storage, and the entry and exit and stacking of goods should be reasonably arranged according to the volume of the cold storage, ventilation conditions, the type, quantity, packaging and other factors to prevent the heat increase and unevenness in the cold storage.
3. Reasonable use of lighting equipment and doors and windows.
Lighting equipment and doors and windows affect the heat and light of cold storage, should be based on the use time of cold storage, the characteristics of goods, personnel activities, reasonable use of lighting equipment and doors and windows, to avoid too long or too short, reduce heat loss and energy consumption.
3. Optimize from the aspect of maintenance.
Through a reasonable maintenance plan, Zhongtai Xinhe "Fengyun Energy Box" can find and eliminate the faults and hidden dangers of the refrigeration system and auxiliary equipment in time, so as to effectively reduce the loss of energy consumption.
1. Regularly check the insulation structure and sealing.
Regularly overhaul insulation structures and seals, repair or replace damaged materials, improve insulation and prevent heat penetration.
2. Clean the refrigeration system and auxiliary equipment regularly.
Regularly clean the refrigeration system and auxiliary equipment, remove pollutants, replace or add refrigerants, lubricating oils, etc., to improve refrigeration efficiency and energy saving.
3. Test the operating parameters of the refrigeration system and auxiliary equipment.
Regularly test the operating parameters of the refrigeration system and auxiliary equipment, adjust or eliminate abnormal values such as pressure, temperature, current, voltage, etc., replace faulty parts, and improve the operation stability and energy-saving effect.
Fourth, optimize from the management aspect.
A reasonable management scheme can standardize the operation and use of refrigeration systems and auxiliary equipment, improve the efficiency and quality of cold storage, and effectively save energy.
1. Formulate and implement reasonable operating procedures.
An operating procedure is a document that specifies the switching of refrigeration systems and auxiliary equipment. According to the situation of cold storage, reasonable operation procedures should be formulated and implemented to avoid disorderly or excessive switching and reduce energy consumption and loss.
2. Formulate and implement a reasonable maintenance plan.
An overhaul plan is a document that specifies the overhaul of refrigeration systems and auxiliary equipment. According to the situation of the cold storage, a reasonable maintenance plan should be formulated and implemented to avoid missed inspection or over-inspection, and ensure the normal operation and life of the equipment.
3. Adopt Internet of Things technology.
The application of Internet of Things technology in cold storage management has significantly improved the level of intelligence and energy saving. Zhongtai Xinhe's "Fengyun Energy Box" is an intelligent cold storage management system developed by making full use of this technology. The system can monitor and adjust the cold storage environment in real time to ensure the stable operation of the cold storage, reduce energy loss, and effectively save electricity costs.
Fifth, optimize from the aspect of energy-saving technology.
Reasonable energy-saving technical solutions can effectively reduce the energy consumption and emissions of refrigeration systems and auxiliary equipment while ensuring the refrigeration effect and quality of cold storage, so as to achieve the purpose of energy saving.
1. Adopt frequency conversion speed regulation technology.
Frequency conversion speed regulation technology is a technology that changes the frequency of the power supply to adjust the speed of the motor, which is used in the refrigeration system, which can automatically adjust the speed of the motor equipment according to the temperature change of the cold storage, saving power and prolonging the life of the equipment.
2. Adopt thermal utilization technology.
Heat utilization technology is the technology of waste heat in refrigeration system. When used in cold storage, the high-temperature gas or refrigerant discharged by the compressor can be used to supply hot water, heat air, defrost, etc., and save electricity.
3. Adopt photovoltaic power generation technology.
Photovoltaic power generation technology is a technology that uses sunlight to generate electricity. When used in cold storage, photovoltaic modules can be installed on the roof or surrounding open space to convert solar energy into electricity, which can be used by refrigeration systems or other equipment to save electricity.
Sixth, from the aspect of energy-saving equipment to achieve optimization.
By adopting a reasonable energy-saving equipment solution, we can reduce the failure rate and maintenance cost of the refrigeration system and auxiliary equipment while ensuring the performance and safety of the cold storage, and achieve energy saving.
