Meilleures pratiquesLiterature: Chilling Facts
The seventh edition of the Environmental Investigation Agency’s (EIAs) Chilling Facts demonstrates that the uptake of HFC-free technology is rapidly advancing in the EU, especially in Eastern and Southern member countries. Since 2008, EIA has been conducting surveys on the use of natural refrigerants in various EU supermarket chains. Annual reports document the market-shift towards climate-friendly refrigerants among some of the world’s leading retailers, as well as warning slow adopters of possible financial problems. In the lastest edition of Chilling Facts, the EIA estimates that 9000 CO2 transcritical systems are in use EU-wide. 6000 additional systems are expected yearly as the EU F-gas phase down progresses. Moreover, innovative CO2 transcritical systems with parallel compression and ejector technology will enable the use of CO2 systems in warm countries. …
Meilleures pratiquesSuccess story: first CO2 training facility in South Africa
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. …
Meilleures pratiquesProduct: CO2 Booster System ONYX
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. …
Meilleures pratiquesSuccess story: Green Cooling labels for refrigerants in Grenada
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. …
Meilleures pratiquesProduct: Transport refrigeration unit
In cooperation with Transfrig, the only South African manufacturer of transport refrigeration systems, GIZ South Africa has completed field testing of a R290 prototype refrigerated transport system in 2017. The R290 prototype has a global warming potential (GWP) of just 3, compared to 3922 of conventional R404 systems. The main aspects that were addressed during the design of the system were circuit optimization and integration of safety measures in order to achieve the same cooling capacities as R404 systems, whilst maximizing the coefficient of performance and reducing refrigerant charge. A leak identification feature was integrated into the system, whereby a suspected leak would result in a shut-down of the system. The product was developed under the project “Emission mitigation in the transport refrigeration sector through the introduction of innovative logistics and supply structures in South Africa”. It is funded by the German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB), with the South African Department of Trade and Industry as the leas executing agency. …
Meilleures pratiquesProject: Green Chillers Indonesia
The Green Chiller NAMA project supports Indonesia in creating framework conditions to improve energy efficiency and sustainability in the refrigeration and air-conditioning sector. Through development of a Nationally Appropriate Mitigation Action (NAMA) in the refrigeration and air-conditioning (RAC) sector a significant contribution to the achievement of the Indonesian GHG mitigation target will be made. The project focuses on four main areas: 1. NAMA strategy development 2. Establishment of incentive systems 3. Implementation of pilot measures 4. Capacity building …
