Reputedly, if the Taklimakan Desert is fully covered with solar panels, the resulting electricity can meet the demands of all countries around the world.
The Taklimakan Desert is rich in sunshine resources, and its ultimate temperature can reach 70 to 80 ℃. As calculated, it takes only 40,000 square kilometers of solar panels to generate the electricity required for the whole of China. China’s gross power generation accounts for about a quarter of that of the world, and China has about 330,000 square kilometers of deserts (330,000÷40,000=8.25), so, in theory, the annual solar power generation can power the whole world for two years in addition to China.
Although solar power generation for global electricity consumption is currently just a theory, SDD vaccine refrigerators have been developed for guaranteeing the storage and inoculation of vaccines.
The African continent is one of the highest environments on the planet, however, due to insufficient power coverage and incomplete public and medical facilities, the storage and transport of vaccines and medicines can cause problems in the cold chain.
Directing at the objective conditions, Haier Biomedical has independently developed the SDD Vaccine Refrigerator, which can make use of the abundant sunshine resources in Africa, to ensure secure vaccine storage even with a power outage.
Highlight 1: Solar Direct Drive
Entirely direct driven by solar power rather than electric supply, the refrigerator is green and environmentally friendly.
The refrigerating unit can maintain efficient output regardless of the changes in natural light intensity. The compressor control algorithm can maintain stable refrigeration under unstable conditions and ensure efficient cold energy storage, sustaining power to the unit for more than 5 days.
Highlight 2: Superior holdover time
The refrigerator can ensure secure vaccine storage without any battery and electronic control system. It can maintain the inner temperature below 2-8° for as long as 160 hours.
This technology now has been applied globally, serving 45 million children worldwide and boosting the basic immunization coverage rates in low-income countries.
Highlight 3: High security
Certified by WHO/PQS and manufactured with Class A anti-freezing function and patented heat pipe design, the product can provide superior temperature uniformity and guarantee the required inner temperature.
In addition, Haier Biomedical’s SDD Cold Storage, SDD Blood Refrigerator, and Ice-Lined Refrigerator are also playing an important role in ensuring the secure storage of vaccines, blood, and samples in remote and power-deficient countries, making their contributions to global immunization.
