How to improve cold storage energy efficiency and save electricity in the design and construction of cold storage facilities? Electricity consumption in cold storage is always a concern when considering cold storage energy efficiency. Many customers want their cold storage facilities to consume less electricity to save costs. Below is a detailed explanation.
The design, installation, and configuration of a cold storage facility should be scientific. They must be reasonable to meet its actual usage requirements. Only when operating in optimal conditions can the refrigeration equipment achieve the best energy-saving effect. Similarly, only in its optimal operating state can the cold storage ensure the best energy-saving mode for refrigeration units and equipment. Therefore, the proper installation of refrigeration equipment, setting of temperature controllers, and adjustment of expansion valves are critical for cold storage energy efficiency. Additionally, the layout of pipelines, charging of refrigerant, pipeline pressure, and refrigeration oil addition affect the operation. They directly impact the cold storage's electricity consumption. Therefore, choosing an excellent cold storage engineering company for design, installation, and commissioning is crucial for optimizing cold storage energy efficiency. It ensures the system operates in its optimal state.
I. Energy-efficient design for cold storage installation
1. The selection and operating efficiency of the refrigeration unit largely determine the power consumption of a cold storage facility. Cold storage installation can reduce operating power consumption by optimizing the refrigeration system configuration and improving equipment efficiency. Considering these methods is imperative for cold storage energy efficiency.
2. The refrigeration system uses fluorine-based refrigerants. Fluorine-based refrigeration systems consume less energy than ammonia-based systems, are safer and more reliable, and have no usage restrictions.
3. The cold storage building materials have good thermal insulation capabilities. This reduces cold loss, improves refrigeration efficiency, and reduces power consumption.
4. The cold storage refrigeration unit is installed in a low-temperature, dry, and well-ventilated location. This setup is conducive to the operation and heat dissipation of the unit. It reduces power consumption, lowers maintenance costs, and extends the service life of the cold storage.
5. The cold storage is built in a cool room. It is equipped with sliding or electric doors. Methods such as air curtains or insulated door curtains help reduce cold loss when the door is opened. This helps reduce power consumption. Furthermore, the cold storage uses high-quality refrigeration equipment with high efficiency, stable operation, and fast cooling speed, reducing power consumption.
6. For multi-warehouse cold storage, multiple units are more flexible than a single unit. This flexibility helps reduce power consumption when storing less goods.
II. Energy-saving management of cold storage facilities
In addition to the design and quality of the cold storage facility, daily use significantly impacts its energy consumption. Proper management methods reduce energy use and ensure efficiency, lower maintenance costs, and extend the facility's lifespan.
1. Reducing the opening time and frequency of cold room doors can reduce cold loss and energy consumption.
2. Conducting warehousing operations and ventilation during cooler nighttime or early morning hours can prevent high temperatures. This approach reduces the energy consumption of the cold room and ensures the quality of stored goods.
3. Setting up automatic defrosting for the cold room according to actual conditions is important. Timely defrosting ensures cooling efficiency and prevents increased energy consumption due to frost buildup.
4. For multi-unit cold rooms, when cooling demand is low, control the number of units started. This action reduces energy consumption and the cooling load on the equipment, further enhancing cold storage energy efficiency.
