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.… read more

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… read more

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… read more

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… read more

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… read more

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… read more

World Refrigeration Day (WRD) raises awareness about refrigeration and air-conditioning and their contribution to modern life. WRD is widely supported by industry associations, organizations and societies as well as governments and individuals. It memorializes the birth date(June 26th)of Lord Kelvinforwhom the Absolutetemperature Kelvin Scale… read more

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… read more

This document suggests how the recommendation of the World Customs Organization (WCO) on establishing additional digits in the existing 2017 national HS codes to identify specific HFCs could be implemented.

One of the primary ways that countries implement their commitments under the Montreal Protocol and particularly the Kigali Amendment is through the monitoring and control of import and export of controlled substances. This fact sheet provides various options for Article 5 countries on how to deal with seized refrigerants in cases of illegal… read more

Refrigeration and air-conditioning is crucial for our health, nutrition, comfort and well-being. From prevention of food wastage to preservation of vaccines, from air conditioning in hospitals to our homes, we increasingly rely on the advances that refrigeration has brought us. However, all around the world the sector has always been a largely… read more

Over the last three decades, the world has realized that the safest and efficient fluorinated refrigerants that were used for decades, contribute negatively to global warming and ozone depletion and threaten life on earth. Because of this, governments and industry engaged in legal and research efforts to find alternatives in order to control… read more

This Webinar, on World Refrigeration Day (WRD), on Refrigerants for Life and how they affect modern life, intends to capture the overall global picture of policies, research,and trends of using refrigerants in different applications while presenting the role of industry, governments,and individuals in ensuring the Responsible Use of… read more

PRAHA-II is a continuation of the process with specific goals that are aligned with the findings of PRAHAI. The two main findings of PRAHA-I are that, 1) there are viable alternatives at High Ambient Temperature (HAT) conditions which need optimized equipment design to perform and deliver the energy efficiency minimum requirements, and 2) that… read more
