Weidmüller energy meters help create a green cold chain

Spring blossoms and autumn fruits, fruitful. Throughout the year, in the north and south of the river, we have long been able to taste the fresh fruits of various seasons and different regions at any time. The supply of colorful and sweet fruits is due to the increasingly prosperous cold chain logistics, and a crucial part of it is the agile development of fruit cold storage.

　　Shaanxi is a well-known hometown of fruits in the country, and the apples in Luochuan, Baishui and other places have long been famous. As far as a fruit industry group is concerned, it is hoped to build a large-scale cold storage to select, pre-cool and put the abundant fruits into the cold storage for long-term storage, so as to effectively extend the preservation cycle and prevent it from eroding and metamorphosis due to storage in the natural environment, so as to be able to supply fresh fruits to the market stably throughout the year.

The issue of energy consumption is the focus of attention of cold storage users. For a power technology company, the general contractor of this large-scale cold storage project, the power monitoring and energy consumption management of cold storage can be described as an inevitable challenge. With the help of energy meter solutions from the electrical connection and automation specialist Weidmüller, the power monitoring of the cold storage has been greatly improved.

The "Behemoth" of Energy Consumption

Large-scale cold storage can be described as a "monster" of electric energy consumption, cold storage operation electricity costs in the cold storage operating cost occupies a large share, cold storage early and mid-term operating costs are basically electricity costs. Under normal circumstances, the freshness temperature of raw fruits is generally around 2-8°C, and the power consumption per hour will reach about 18kWh.

The source of energy consumption of cold storage mainly comes from the refrigeration system, compressor, condenser and evaporator and other large-scale equipment, and the high cost of energy consumption and the backwardness of refrigeration technology are also a problem in the construction of cold chain in China at that time.

In order to complete the transparent operation of cold storage and digital energy consumption management, the power technology company first needs to collect and monitor the electricity consumption data of the entire cold storage, and finally upload it to the cloud data channel to complete the visualization, so as to provide early warning before the electricity consumption overrun. Together, in addition to the collection of electric energy data, cold storage operators also need to have a recosting function, and so on.

"Green" helps freshness

The EM220 multi-function meter supplied by Weidmüller just meets the energy saving and consumption reduction needs of large energy consumers such as cold storage, especially to help operators use power more effectively and maximize the utilization rate of the power network, and complete the dual benefits of economic and social responsibility.

From the perspective of energy meter planning, the value of EM220 energy meter to cold storage operators is not only to measure power loss. Through the electric energy meter, the cold storage operator can not only determine the basic parameters of power quality, especially through the 4DI and 2DO communication that comes with the electric energy meter, it can complete long-distance monitoring and shutdown, but also can conduct separate analysis or difference analysis of the current of the cold storage operation equipment, which becomes the data analysis basis for the equipment energy consumption ranking, and finally helps the cold storage operator to quickly grasp the power profile of air conditioning compressors and other equipment - this is not only related to the efficient use of electric energy, but also an important guarantee for power quality, stability and utilization rate.

Based on excellent intelligent planning, and further relying on the precision workmanship and sophisticated digital display touch screen planning of the Germany brand, the EM220 energy meter quickly won the approval of the general contractor, and directly changed the power distribution drawings and actual acquisition deployment after the trial. The power monitoring solution is a good combination of customer and channel collection needs, its cost-effective, exquisite and easy-to-use interactive interface and long-distance processing capabilities, in addition to helping energy consumption monitoring, but also saving the cold storage operator protection costs.

As for the use of high energy consumption such as cold storage, the completion of more in-depth energy consumption analysis and management according to the visual monitoring of energy consumption is becoming the focus of enterprises towards green and sustainable development at that time. Weidmüller's power monitoring and control solutions centered on energy meters are bound to provide "green" support in this process.
