In November 2015, Walton launched a new line of refrigerators that run on the natural refrigerant isobutane. The project was supported by the United Nations Development Programme under Bangladesh’s national HCFC phase-out management plan (HPMP). The market transition to green cooling technologies will avoid 65 MT of HCFC-134a emissions annually, as well as savings of about 14 million kWH annually. The project was successfully completed by the end of 2016, and was implemented in a cost-effective and safe manner. …

Fresnel-solar Cooling system for industrial facility in Jordan Industrial Solar GmbH provided a Fresnel collector field with a total capacity of 700 kW(th) to an industrial facility in Jordan. Besides process heating the solar steam also powers a double effect absorption chiller which is directly connected to the central cold supply of the facility. …

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. …

Since May 2018, the National Ozone Unit (NOU) of Grenada, in cooperation with GIZ Proklima, has been providing Green Cooling stickers to local appliance stores in order to promote the dissemination and use of natural refrigerants on the island state. The initiative created by both project partners supplies local appliance stores with eye-catching green magnetic stickers which are fixed on refrigeration systems with natural refrigerants. As a result, both the distributors and the customer alike are provided with a convenient tool for the promotion and distribution of natural refrigerants, and thus for ozone and climate protection. First piloted with the two companies Courts Grenada Limited (UNICOMER) and L. A. Purcel, the NOU aims to involve more retailers and suppliers and expand the initiative also to air conditioning technologies, with the goal of eventually making Grenada the first f-gas-free Caribbean island. …

In 2012/2013, Glaciem Cooling Technologies in collaboration with the University SA Barbara Hardy Institute and Alltech Refrigeration launched the Parilla Potato Project. Parilla Potatoes is a large, refrigerated storage facility located in South Australia. The basis for the design of the Parilla Potato Project is a secondary refrigeration system that uses a critically charged ammonia chiller as the primary refrigerant and Dynalene HC30 as a secondary refrigerant. Moreover, the design also includes the use of a Thermal Storage System using Phase Change Material (PCM). The PCM is cooled by the primary ammonia plant overnight using off peak electricity, and the Dynalene uses the thermal storage of the PCM to provide refrigeration during peak operating hours. In 2014, the system won the AIRAH Best HVAC&R Retrofit/Upgrade award. …

Between July 2011 and 2014, Walton phased out the use of HCFC-141b in its manufacturing of insulation foam for domestic refrigerators, resulting in savings of 183.7 MT of HCFC-141b in Bangladesh. At the 62nd Meeting of the Executive Committee of the Montreal Protocol, the Multilateral Fund approved Walton’s project to convert its HCFC-141b foam production line to the environmentally-friendly cyclopentane technology. The projected was funded by the United Nations Development Program. …

Industrial Solar has installed a Fresnel Collector system for the leading South African mobile network operator Mobile Telecom Networks (MTN) in Johannesburg. The project falls under the global “Solar Roofs Program” which was launched by the Deutsche Energie-Agentur (dena) in 2004 and co-financed by the German Federal Ministry of Economics and Technology (BMWi). The goal of the Solar Roofs Program is to install demonstration projects on the roofs of designated institutions around the globe. Comprehensive marketing and training programs accompany the installation. A Fresnel Collector System is a linear concentrating solar thermal collector optimized for industrial use. The system has a thermal peak power of 272 kW and an absorption chiller with a capacity of 350 kW. The cold is directly delivered into the local cooling network, hereby reducing fossil fuel consumption and CO2 emissions. …

Amman, October 2016: After 4 years of careful planning and developing, GIZ and the Jordanian Ministry of Environment (MoEnv) have successfully completed the solar cooling project at the German Jordanian University. The university in Amman now relies on a solar-powered cooling system that operates with a high reliability and environmental effectiveness, reducing electricity consumption for cooling by 15%. The project demonstrates the feasibility of environmentally-friendly technologies in Jordan, hereby promoting the reduction of CO2 emissions in line with the new Renewable Energy & Energy Efficiency Law, the phasing out of hydrochlorofluorocarbons (HCFCs), and Jordan’s scoping study on Green Economy. With several stakeholders from Germany and Jordan, the project promotes the cooperation between its different partners such as technology providers, German and Jordanian research institutions and Jordanian chiller manufacturers. …
