In November 2019,the "2019 National industrial Energy Saving Technology and Equipment Recommendation and "Energy Efficiency Star" Product Evaluation Work" was successfully concluded ral Office of the Ministry of Industry and Information Technology of the People's Republic of China (No. 123 of the Section Letter of the Department of Industry and Information Technology [2019]), and after the organization of the local competent departments of industry and information technology, the industry associations' recommendation and evaluation, the Ministry of Industry and The Ministry of Information Technology included 86 industrial energy-saving technologies and 193 items of industrial equipment into the "National industrial Energy Saving Technology and Equipment Recommended Catalogue (2019)", and 50 items of industrial equipment and 84 items of end-consumption products into the "Energy Efficiency Star" Product Catalogue (2019). The high-efficiency subcooled water-type ice-making unit jointly developed by Moon-tech Energy Conservation Technology Company/Guangzhou Moon-KoLin was selected as a key energy-using equipment system energy-saving technology.

12 | High-efficiency subcooled water type ice-making unit | Through the refrigeration host generated by the low-temperature glycol solution or refrigerant direct evaporation of the cold produced by the water in the ice storage tank through the dynamic ice machine group in the subcooled heat exchange cooling into -2 ℃ subcooled water, and then through the ice machine group in the ultrasonic device to promote crystallization to lift the subcooling to generated ice slurry, through the pipeline to the ice storage tank; ice-making process relies on high-speed convection heat transfer and thermal conduction of heat transfer, the coefficient of heat transfer is large, the exchange of heat does not ice, ice-making, heat transfer and ice-making is completed in two steps, fast and constant ice-making. When making ice, there is no heat transfer, heat transfer and ice-making are completed in two steps, and the ice-making speed is fast and constant. | Suitable for air conditioning, ice making, pre-cooling, etc. | 2% | 24% | 2.94 |
High-efficiency subcooled water-type ice-making unit aims to provide a complete set of safe, environmental friendly, energy-saving ice-making and cooling storage system solutions through the study of high-efficiency ice-making methods, which can be flexibly applied in various fields such as commercial building air-conditioning, residential building air-conditioning. Industrial refrigeration, food processing, large-scale regional cooling system, etc., and at the same time, solve the contradiction between supply and demand of electricity. This project has been successfully promoted and applied to many units, the results of the project are widely used to improve production efficiency, improve the human living environment.
