Qingdao Arctic Ocean Cooling and Heating Energy Technology Co., Ltd., located in the high-tech business incubator of the "China-Shanghai Cooperation Organization Local Economic and Trade Cooperation Demonstration Zone", is an enterprise specializing in the research and development and application of high-end cooling and heating technology. The company has a domestic first-class technology research and development and management team, and maintains a leading position in product technology, production, quality assurance, service and operation management. The main business covers energy-saving equipment R&D and manufacturing, energy-saving engineering transformation, project operation management, mechanical and electrical engineering, and the company has four core technologies: high-efficiency cooling and heating equipment, cooling and heating station integration technology, Guanhai Internet of Things platform, and large-pressure ratio centrifugal compressor. With energy conservation and environmental protection as its own responsibility, and the mission of improving energy efficiency and promoting the upgrading of the refrigeration and HVAC industry, the company is committed to building a domestic high-end operation central air-conditioning brand and practicing the "double carbon" goal with practical actions. The company attaches great importance to the research and development and application of new technologies, and has carried out industry-university-research cooperation with Nanjing Institute of Technology, Shandong University of Science and Technology and other universities. We continue to innovate, continuously improve operational elements with technological innovation, keep an eye on the goal of carbon neutrality, serve professional heating (cooling) operators, and create high-quality operation projects. Now it has been recognized as "high-tech enterprise", "specialized and special new enterprise", "one enterprise and one technology", etc. At present, the company has more than 50 core technology patents, covering various fields such as system energy-saving control, large pressure ratio centrifuge, inverter water cooling unit, air source heat pump, dual-source tower system, Internet of Things service and so on. It has 3 sets of independent system test benches: 1. 500RT-3000RT independent system water-cooling test bench: the leading level of domestic testing capabilities, covering the mainstream cooling capacity section at home and abroad, the experimental medium covers water, ethylene glycol, calcium chloride and other substances, and the test temperature range is -40°C~85°C; 2. 50RT-500RT independent system water-cooled test bench: the experimental medium covers water, ethylene glycol, calcium chloride and other substances, and the test temperature range is -40°C~85°C; 3. 280KW ultra-low temperature air-cooled laboratory: the ambient temperature range can reach -40~60°C.
