Companies from Latin America, the Caribbean and Europe took us on a virtual tour to their ozone- and climate-friendly RAC systems. In a video series, companies reported on their experience of various applications based on ammonia, propane, CO2 and isobutane.
AC based on propane and CO2, GIZ Campus Bonn, Germany
The office buildings at GIZ Bonn were built in 2015 (Mäander building) and 2020 (GIZ Campus). Sustainability was very important in the planning process, also in terms of ventilation and air conditioning. Even the refrigerants contained in the heat pumps have been carefully selected. The air conditioning system of the Mäander building is based on 66 kg propane while 450 kg CO2 are used in the Campus building. Both refrigerants are ozone- and climate-friendly due to their very low Global Warming Potential.
Industrial refrigeration with CO2, ammonia and propane: Intarcon Spain
Intarcon is a global supplier for packaged refrigeration units and solutions for the catering and food distribution sectors and the industry. The company distributes systems that operate with natural refrigerants. Discover Intarcon's refrigeration systems based on propane, CO2 and ammonia!
Refrigeration with R290: Roche in Costa Rica
Roche sends biotechnological medicines from its distribution center to more than 23 countries in the entire Central American and Caribbean region. Two cold rooms with the natural refrigerant R290 store all products requiring a cold chain of 2°C to 8°C degrees, mainly medicines for cancer treatment. A freezing room is used to store refrigeration elements to maintain the cold chain during transportation.
Industrial refrigeration with ammonia: RSF Costa Rica
RSF provides insights into how they installed refrigeration systems at a Coca Cola plant in Costa Rica and what considerations played a role in doing so. The systems used, equipped with ammonia, are highly energy efficient and climate-friendly. Additionally, the refrigeration, air conditioning and process water systems are equipped with monitoring devices to avoid waste.
Industrial Conversion to R600a: Mabe in Mexico
Mabe is the leader for home appliances in Latin America. The company's goal is to eliminate the conventional refrigerant R134a and replace it with the natural refrigerant R600a. Since the start of this project, Mabe has avoided emissions to the environment of more than 240,000 tonnes of CO2 equivalent.
Air Conditioning with R290: Ministry of Transport of Costa Rica (MOPT)
The MOPT replaced its old ACs by inverter ACs based on R290 refrigerants. A total of 20 eco-efficient air conditioners were installed in 2019.
R290 AC Distribution: Grenz Concept Grenada
Grenz Concept is an AC distributor based in Grenada. The company installed the first R290 unit in May 2019. Since then, the success of these units has been tremendous: Costumers are very happy with these ACs based on hydrocarbons.
R290 AC Distribution: Modern Electrical Solutions Grenada
Modern Electrical Solutions is an AC distributor based in Grenada. Founded in 2012, the company keeps Grenada naturally cool by installing R290 units to replace climate damaging refrigerants.
All videos have been produced for the virtual Technology Roadshow 2021. It has been organised by GIZ Proklima (SPODS project) with the financial support of the European Union (EU) and German Federal Ministry for Economic Cooperation and Development (BMZ).
