A long power outage in the summers means sweat, and heaps of food gone bad. And, in case your refrigerator was being used to store medical supplies the situation gets even worse. In third world countries power failures are common, as are high temperatures – a combination which is certainly not apt for things that need to be kept cold. Here’s where the True Energy Vaccine Refrigerator comes into play. This cooling machine can store $30,000 worth of medicines below 10C (50F) in 43C (109F) ambient temperatures, for over ten days without power.
The refrigerator incorporates True Energy’s Sure Chill technology, which utilizes high-density polyurethane foam insulation and a yet-to-be-disclosed “innovative phase change material” to store energy until it’s needed. This allows it to consistently cool temperatures, regardless of interrupted power supply. A True Energy Refrigerator can run indefinitely on less than five hours of mains power per day. Once fully charged, the phase change material can keep the fridge going for ten days without any power input at all. This non-battery power-storing capability is also said to make it twice as energy-efficient as compared to similar products.
Utilizing an intelligent monitoring system, it detects warm objects within its cabinet and reacts to extract heat, keeping all of its contents at a temperature of between 4 and 6C (39 and 43F). True Energy Vaccine Refrigerators are currently in use by agencies such as the World Health Organization and Unicef. The company is also looking into utilizing its Sure Chill technology in various other products that act as coolants.
