We are pleased to announce the selection of the first 5 Case Studies to be presented at the UNIDO ATMOsphere conference. Below you will find a short summary of the selected case studies.
We are also very happy to announce 5 new Sponsors for this event: Danfoss, Obrist Engineering, Kawasaki, enex and Settala Gas.
Technology Case Study Selection- Part 1
Conversion of HCFC-22 based facilities to ozone and climate friendly alternatives in the Fishing / Food Processing (Servicing) sectors in Viet Nam by UNIDO
Viet Nam is one of the leading countries for aquaculture, aquatic product processing and export in the world. According to the Ministry of Natural Resources and Environment (MONRE), there are around 400 cold storage facilities used for fisheries, each with an average of 10 refrigeration machines running on HCFC-22. Most of the technologies used are high carbon emitting and low energy efficient. Due to the age and particular design of the cold storage systems there is great room for improvement. However, the overall lack of policy and regulatory incentives in Viet Nam makes it difficult to move away from HCFC-22 before 2040 and consider lower-carbon, low-GWP alternatives. To address these issues, UNIDO has created an opportunity for the conversion of the existing installations with low-GWP and energy efficient technologies through resource mobilization – co-financing of activities by Global Environment Facility (GEF).
R-290 as an alternative refrigerant for split air conditioning systems in high ambient temperatures by Godrej/GIZ
The presentation addresses the performance of an R-22 split type air conditioner and an R-290 air conditioner specifically for very high ambient temperatures. The result of the equipment tested shows a very good capacity and coefficient of performance (COP) for the R-290 system. Further modeling exercises indicate that adjustments in terms of the characteristics of the evaporator and condenser can help improve the performance at high ambient temperatures. However, R-290 is a flammable refrigerant, meaning that safety considerations must be given to its use. Given that high ambient temperatures imply larger heat loads and therefore greater cooling capacity and refrigerant charges, additional deliberations are necessary to address the constraints and associated risks.
Promoting low-GWP refrigerants for air-conditioning sectors in high-ambient temperature countries by UNIDO
The choice of available, viable and environmentally sound HCFC alternatives for air-conditioning sectors in high-ambient temperature regions, such as the Gulf countries, is still a challenge. The most feasible refrigerants currently available for countries with specific climatic conditions represent high-GWP solutions, while the potential alternatives with low-GWP are still in the early stage of development. The latter raises the concern whether the HCFC freeze and reduction targets set by the Montreal Protocol can be met. In addition, new energy savings requirements being applied in the Gulf countries (such as KWh reduction per TR, while increasing air-conditioning unit design temperature to 48 ºC and) result in disqualification of most commercially available alternatives there. In order to address the above concerns and accelerate the phase-out of HCFCs, this UNEP/UNIDO project aims to find and promote environmentally sound solutions, applicable for high-ambient temperature regions, for the air-conditioning sector in the Gulf countries.
Emerging countries in natural refrigerants by CAREL
This case study will focus on South America and South Africa and their progression and development in CO2 technology. It will provide an overview of the early development of alternative natural solutions from both a Contractor and OEM perspective, which encourage the local industry to embrace a natural alternative and also raise awareness for a more sustainable future. The South American case highlights Bitzer's drive (OEM) to develop a state of the art CO2 excellence centre with the help of CAREL Sistema CO2 solutions, in order to demonstrate the opportunities to be gained with CO2 as an alternative working fluid and also to train the local industry. This is a reflection of the vision which the South American market would adopt without any barriers in terms of working with CO2 refrigerant and the investment outlay. It aims to push the industry towards uniformity in terms of awareness of CO2 and best practices.
Safe and responsible usage of natural refrigerants by Danfoss
The phase out of HCFC’s will challenge decision makers on the selection of future refrigerants. Many parameters have to be observed to ensure a sustainable choice that encompasses efficiency, safety and cost. Not observing these factors is a direct risk to successful proliferation of climate friendly refrigerants. A single mishap, whether due to a failure of safety or due to a failure to provide the promised reduction in operating costs can have far reaching consequences. By building safety into the components and by taking measures to ensure the safe and responsible use, Danfoss now allows these components to be sold globally. This case shows the considerations behind product development and the process to ensure a safe use of components including an education program carried through by Danfoss in Brazil. It also highlights the need to provide guidance in terms of choosing the right solutions per application to provide the greatest customer benefit. The case relates how these practices have led to concrete examples of success in Brazil (Heineken propane bottle coolers and Verdemar CO2 supermarkets).
Next week we will announce the 2nd round of selected Technology Case Studies for UNIDO ATMOsphere.
