Ubiblue's Compact Magnetic Refrigeration System (MRS) is a stand-alone unit with a refrigeration power of 400W and a temperature span of 25°C, making it the ideal solution for a range of small-scale applications. The use of permanent magnets may reduce energy costs by up to 50%. Magnetic cooling is becoming an ever-increasing solution used for the cold industry. In a MRS, a controlled magnetic field applies a series of magnetization-demagnetization cycles to the magnetocaloric alloys. Each cycle produces a temperature gradient in the material, and a rapid succession of these cycles produces the final and stabilized hot and cold temperatures in the refrigeration system. Moreover, the MRS uses glycol as a coolant, such that is not environmentally harmful. This technology resolves the two main concerns regarding compressor-bases refrigeration systems: the environmental issue via a gas-free solution as well as the economic issue by using permanent magnets that dramatically reduce energy consumption. …

Introduced by Shecco in 2009, the Natural Voice is a global statement open to industry, associations, non-profit organizations and individuals supporting the potential of natural refrigerants in replacing potent greenhouse gases. At present, the Natural Voice has 109 signatories from a range of sectors and industries. The statement will be presented to national governments and international climate negotiators in the near future to build the basis for developing natural refrigerant initiatives around the world. The Natural Voice demands national governments to remove (inter)national trade barriers and to revise safety standards, codes and legislation that restrict the use of natural refrigerants without merit. Furthermore, it calls upon national governments to provide (non-) financial support for the research and promotion of natural refrigerants, and to facilitate the technology transfer from developed to developing countries. …

Johannesburg, February 2016- Commercial Refrigeration Services (CRS) has opened the first ever CO2 training facility and showroom in South Africa. The new facility is used to train local technicians and contractors on installing and maintaining CO2 systems. Groenwald, CRS’ head of engineering, manufacturing and installations said that “knowledge and experience are the barriers standing between CO2 refrigeration applications becoming the mainstream solution for the African market”. The readily accessible CO2 facility in Johannesburg is helping local technicians to understand the climate-friendly and energy-efficient efficient alternative refrigerant. The facility resembles a small supermarket with three different CO2 refrigeration systems: a booster system, a booster system with parallel compression and a booster system with parallel compression and an ejector. By measuring and analyzing the energy consumption by the different types of systems, CRS may demonstrate to the end users the monetary, energy and ecological benefits of each CO2 refrigeration system. …

The ONYX series are simple, integrated transcritical booster systems for medium (MT) and low temperature (LT) supermarket applications designed by Commercial Refrigeration Services (CRS) South Africa. The ONYX CO2 booster system makes use of parallel compression and ejectors, increasing energy efficiency by 25-35% and making CO2 a viable refrigerant choice even in high temperature regions. ONYX uses a two-stage compression cycle with a common condenser and liquid line for MT and LT applications. The two-stage design prevents significant energy losses as no big heat exchangers are required to condense the LT side. The integrated multi-temperature solution thus allows each ONYX unit to fully exploit the advantages of CO2. …

CRS – CO2 only refrigeration systems Commercial Refrigeration Services (CRS) focuses on refrigeration installations using the latest CO2 technology. With a commitment to continuous development and providing clients with future-proof solutions, CRS has become a forerunner in sustainable, environmentally friendly and energy-efficient cooling and heating. Following various industry-changing breakthroughs, CRS’s first CO2-only refrigeration system launched in 2010. The drive to create the best CO2 solution in Africa for Africa led to even more improvements and the development of the first CRS Booster System in 2012. Each one of the solutions features technology-driven design and implementation, top-quality components and industry best practices. To date CRS has over 50 stores operating on CO2 refrigeration systems, which they are proud to say have all been designed and manufactured in South Africa. …

CAREL’s evaporative ChillBooster accommodates comfortable learning conditions in the world’s largest female-only university, the Princess Nora bint Abdulrahman University in Riyadh, Saudi Arabia. The ChillBooster is an evaporative cooler which cools air and lowers its average condensing pressure before the air is used by the condensing units such as chillers or dry coolers. Spontaneous evaporation is favored by the atomization of water in micrometric droplets, reducing the thermal energy required for evaporation from the surrounding air. Having opened in May 2011, the Princess Nora bint Abdulrahman University has a capacity of 50,000 students and hugely promotes female education. The ChillBooster guarantees a higher absorption ratio and less hygiene problems compared to the appliances typically used in such situations. …
