Ice storage is recognized by many people as a refrigeration solution that fully utilizes the national peak-valley electricity policy. Its mode of using valley electricity to store cold at night and cooling during the day allows users to maintain the use of cold water in daily central air conditioning and industrial production at low electricity prices.
Before the emergence of Trip ice slurry system, the domestic ice storage mode was still in the coil ice and ice ball ice storage system, which would cause low cold storage COP, large amount of coolant filling, slow ice melting speed, difficult regulation, uneven cooling before and after, easy corrosion and leakage of pipelines, difficult later maintenance, and inability to use holiday valley electricity to expand cold storage capacity!
In order to solve the above problems, Terup and its partners launched a low-temperature ice slurry system. Among the various ice-making and cold storage technologies currently available, this system has the advantages of high efficiency, low cost, and flexible application. It has a wide range of uses in various cold use fields such as ice storage air conditioning, regional cooling, 8~15℃ workshop air conditioning and hallway, high-temperature warehouse, industrial cooling, mine cooling, medical treatment, preservation of fruits and vegetables, fish, shrimp and poultry, milk and beer process cooling, artificial ski resorts, concrete mixing, and LNG cold energy comprehensive application.
Compared with the traditional cold storage direct refrigeration system and coil ice hockey ice storage system, this system has the following advantages:
1. Mature and stable; dynamic ice slurry has been successfully applied to ice storage air conditioning, regional cooling, pharmaceutical chemicals, dairy beverage process cooling, food pre-cooling, artificial ski resorts, low-temperature air conditioning and other cold use fields. Trip has undertaken nearly 100 supercooled water dynamic ice slurry refrigeration projects in 28 provinces across the country;
2. Safe and environmentally friendly; the ice slurry uses municipal tap water (GB5749-2006), without any additives, and can be in direct contact with food, which is safer and more environmentally friendly;
3. Dynamic ice storage technology has been included in the "National Key Energy-Saving and Low-Carbon Technology Promotion Catalog" (2017 Energy-Saving Part), responding to the national energy-saving and emission reduction policy, and reducing 4 million tons of carbon dioxide annually;
4. High-efficiency supercooled water ice making units have been selected in the "National Industrial Energy-Saving Technology and Equipment Recommended Catalog (2019)", responding to the national carbon peak and carbon neutrality policies, saving 29,400 tec/a;
5. With the help of the rapid cooling function of dynamic ice slurry, it fundamentally follows the irregular and violent fluctuations in the dairy production process, thereby ensuring that the material temperature is always below +2°C during the dairy production process, and can bring users a perfect "consistent" product.
6. Interconnection of hot and cold, achieving multiple goals at one stroke; with the help of condensing heat recovery system, 65-70℃ hot water can be provided, further reducing factory steam consumption and operating costs, improving comprehensive energy utilization efficiency, and reducing factory carbon emissions;
7. This dynamic ice slurry unit adopts outdoor models, which does not require the establishment of machine rooms, power distribution rooms and monitoring rooms. It has modular design, is easy to install, and has a short construction period;
8. On the power supply side: use valley electricity to reduce peak power occupation of the power grid, balance the power grid load, and reduce power supply costs;
9. On the power generation side: reduce the requirements for load regulation of power plants, improve power generation efficiency and the safety of equipment operation;
10. Realize peak-to-valley filling of electricity use, improve power supply and demand conditions, promote new energy consumption, reduce the scale of power plant construction, and support the government.
