What is the highest temperature a human can withstand?
Most people will feel uncomfortable if temperature exceeds 35°C, and their work and life will be affected if it exceeds 40°C.
On August 9, the latest report released by the World Meteorological Organization (WMO) pointed out that this summer the world has experienced some of the rarest high temperatures in history. In the past 10 days, temperatures above 35°C have been reported in southern Europe, the UK, and southern North America; persistent high temperatures above 40°C have struck northern Africa and West Asia, with the highest temperature topping 45°C in the past two days.
Unfortunately, the COVID pandemic and monkeypox pandemic have not subsided because of the high temperatures, and they have always been threatening the safety of life around the world. The only way they can be contained is through vaccination.
To ensure its efficacy, the vaccine needs to be stored in a stable low temperature environment. As continuous high temperatures rage across the world, especially Africa where ambient temperature is notoriously high but only a few areas have access to electricity, where could vaccines be stored?
"Haier Biomedical has independently developed a solar-powered direct-drive vaccine refrigerator to ensure safe storage of vaccines even in case of a power outag". Said Enrique, the Director of Africa & UN Project.
According to him, Haier Biomedical has developed an algorithm to control DC direct drive compressors in non-steady state, which delivered efficient cold storage solutions.
If the ambient temperature exceeds 40°C, the compressor and condenser of a common medical refrigerator may perform poorly in dissipating heat. As a result, the temperature could be reduced to the shutdown temperature, and the compressor cannot be shut down and would continue to operate. The Haier Biomedical Solar Vaccine Refrigerator is completely powered by solar energy, and the refrigeration unit would therefore maintain efficient output no matter how the light intensity changes. In the absence of any battery and electronic control system, such a refrigerator can also ensure safe storage of vaccines, and it can operate at 2-8° for up to 160 hours without electricity. It has received the A-level anti-freeze certification issued by WHO. Its patented heat pipe design can provide better temperature uniformity and thus ensure the internal temperature satisfies the requirements for refrigerator operation.
In addition, Haier Biomedical has a perfect after-sales system. Local service personnel would regularly overhaul the refrigerator and show how to use it correctly. The refrigerator is also equipped with RTMD equipment that can observe the operating status of the equipment in real time. In case of a problem, the RTMD equipment would send a warning in time.
Against the backdrop of the prolonged COVID-19 pandemic, this technology has been applied globally, helping low-income countries in their efforts to deliver full basic vaccination coverage.
Additionally, as a global complete cold chain supplier, Haier Biomedical is committed to providing high-quality products and services to medical enterprises, organizations, and research institutes around the world. To meet market demands, we have launched a complete cold chain solution covering production, transportation, storage, temperature monitoring, and vaccination. This solution serves to ensure the safety of vaccines and medicines in extreme conditions.
