At Supermercados Hiber, energy efficiency and environment are key players in the company’s decisions. In 2012, Hiber had the first store in Spain using only CO2 as refrigerant and in 2014 made history with the first Spanish urban CO2 transcritical store.
CO2-based technology results are very attractive in installations such as at supermarkets, where the payback period is relatively gradual and equipment has a long life expectancy.” Ruiz continued. “It is true that costs related to installation and commissioning are higher. However, it allows for about 30% energy savings compared to traditional systems plus the return of investment is also quick (three years).”
These installations have significant energy savings. Just to give you a real example: at a 1000m2 sales area using hydrofluorocarbon R404, your energy bills go over €7000. If you replace this with a TC system, you end up paying less than €5000 per month. Now take this number and consider a life cycle of 10 or 15 years, the savings are great and we don't even have to think about the tax or failures in the system.”
