Video (case study): supermarket in south africa, naturally cool | global 3000
When used as refrigerants, flourocarbons can cause severe damage to the Earth\‚s ozone layer. That\‚s why a South African supermarket chain is changing direction to use natural and eco-friendly refrigerant technologies — and saving money and energy as a result. Electricity is especially costly in South Africa. In the last few years the price has been rising by nearly 30 percent annually. Meanwhile, power shortages have been reported. So a supermarket chain called Pick \‚n Pay is investing in new equipment. Instead of using flourocarbon gases to cool its outlets, it\‚s now using natural refrigerants.
