The cold chain is a series of actions and equipment applied to maintain a product within a specified low-temperature range from harvest/ production to consumption, including farming/fishing, food processing, cold storage, transportation, food services, and domestic uses, as well as special products like medicinal products and vaccines.

8141Food Processing
For consumers, the cold chain is often associated with transport, retail and household refrigerators. But refrigeration is also and widely used in the agri-food industry for the storage of raw materials and final products, as well as for food processing. This brief gives a short overview of refrigeration applications in the industry. The refrigeration technologies in use are briefly presented, according to facility size and temperature requirements, and the problems relating to the use of refrigerants are also discussed.
Publication
8140 Fishing vessel
This brief will present the process needs and applications of refrigeration onboard refrigerated fishing vessels. Currently used technologies and refrigerants will be presented, along with the possible alternatives for new systems. The issues related to the management of existing fl eets and implications to the Montreal Protocol on ozone-depleting substances will also be presented?
Publication
8139 Domestic Ref
Due to the complex nature of the cold chain and the high temperature dependency of post-harvest or post-mortem deterioration in food, temperature control in the food chain is vital. Temperature control tends to become less well controlled at the retail/professional and domestic stages of the cold chain. The food chain is responsible for greenhouse gas emissions through direct (refrigerant emissions) and indirect (energy consumption) eff ects. Published data for overall emissions for each section of a whole cold chain are relatively scarce.
Publication
8142 Transport refrigeration
This brief provides an overview of the main areas of transport refrigeration, some of the different systems used and the working fluids employed. It will go on to look at current trends in using alternative refrigerants and the direction the sector is moving in over a longer period. Future developments will be discussed along with the technical challenges facing designers as they attempt to reach the best balance between what the end-user expects from a system and the framework determined by international treaties and regulations.

8138 Cold storage
Cold storage warehouses store food after production and before foods are transported and distributed to supermarkets or catering establishments. Food is stored either chilled or frozen and may remain in the store for periods of a few hours, days or even a year (for some fruits and vegetables) in chillers and up to several months in freezers. This sector has been shown to be one of the sectors of the cold chain where the temperature of products is well temperature-controlled. Energy usage is important to cold store operators as it is a high proportion of the overall operating costs.

OzonAction Refrigeration and Air-Conditioning Technician Video Series consists of instructional videos on techniques, security and best practice and flammable refrigerant safety. They are intended to serve as a complementary training tool for refrigeration and air-conditioning (RAC) sector servicing technicians to help them revise and retain the skills they have acquired during hands-on training.

GWP Calculator
The new and updated UNEP OzonAction GWP-ODP Calculator application will help you to convert between values in metric tonnes, ozone depleting potential (ODP) tonnes and CO2-equivalent tonnes of substances controlled by the Montreal Protocol and their alternatives. This application, available at no cost, is particularly useful for National Ozone Officers to assist with understanding and calculating quantities of controlled substances, both pure substances and mixtures, for quota assignment, reporting requirements, etc.

One of the ways in which refrigeration cylinders are quickly identified is by cylinder colour. Although there was never a truly globally adopted international standard, the guideline from the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) although not required by law was used by the vast majority of industry and chemical producers around the world.

8131WhatGas Flyer
The WhatGas? UNEP OzonAction application is an information and identification tool for refrigerant gases for ozone-depleting substances(ODS), HFCs, and other alternatives. It is intended to provide a number of stakeholders, including Montreal Protocol National Ozone Officers, Customs Officers, and refrigeration and air-conditioning technicians with a modern, easy-to-use tool that can be accessed via mobile devices or the OzonAction website to facilitate work in the field, when dealing with or inspecting ODS and alternatives, and as a useful reference tool.

An important Montreal Protocol issue that is currently being discussed and will need to be carefully considered in light of the HCFC phase-out Management Plans (HPMP) second or third stages, which are now being prepared and submitted to the Executive Committee, is that of the HCFC ‘Servicing tail’ To avoid any unforeseen challenges in the future, it is crucial that all countries have a good understanding of their likely requirements and plans regarding the HCFC ‘servicing tail’ when preparing for and drafting their Stages II and III.
