The benefits of linear compressors
Three articles published recently in the IJR illustrate the strength of R&D work around linear compressors and highlight the benefits of these, especially in commercial and domestic...
Expansion of cold chain facilities in hot countries
Effective cold-chain logistics are essential for the economic growth of hot countries. In Africa, Asia, as well as the Middle East, various stakeholders are engaged in setting up cold storage refrigeration warehouses and temperature-controlled...
LEGO® block structures as a solution for cryogenic temperature insulation?
British researchers have cooled LEGO® blocks at a temperature of a few mK in an experiment which reveals a possible new application for the material which composes the popular toy.
New Zealand: consultation on future licensing regime for refrigeration technicians
The New Zealand National Committee of the IIR participated in the MBIE consultations in order to seek comments on the proposed refrigeration technicians licensing regime.
Spacewalkers replace the cooling pumps of the ISS cosmic particle detector
Two astronauts just finished successfully repairing the cooling pumps of the Alpha Magnetic Spectrometer fitted to the International Space Station.
A novel method for frost detection
Frost growth on the evaporator coils of a refrigeration plant can dramatically reduce its efficiency. A novel indirect detection method that would avoid frost built-up has been developed.
The race to design individual cooling devices
Cooling individuals would be less energy-consuming and a lot cheaper than cooling entire buildings. Based on that principle, companies, start-ups, and researchers are racing to build wearable devices that can act like mini air-conditioning...
Use of chillers in cannabis greenhouses
The legalisation of medical cannabis in several states in the US involves the development of new techniques to manage temperatures while reducing production costs.
Cooling a drink in a few minutes will be possible soon!
Juno, which is a prototype of "reverse microwave", was featured during the Consumer Electronic Show (CES) that was held from January 7- 10, 2020 in Las Vegas.
First liquefied hydrogen carrier launched in Japan
In line with its commitment to pave the way for the first "Hydrogen Society", Japan intends to use this carrier to transport hydrogen from Australia, where it is produced from lignite.
The Indian government implements a default temperature setting on room air conditioners
The Indian Government has imposed a default temperature setting of 24 °C on room air conditioners with effect from January 1, 2020.
State of the art on the flammability of HFOs
An article recently published in the IJR reviews the flammability characteristics of 48 HFOs and blends for various experimental conditions.
A study assesses alternative mixtures to two pure hydrocarbon refrigerants
An article reviews more than 11,000 mixtures of refrigerants that could be interesting alternatives to pure R290 and R600a.
Latest news on the regulation of flammable refrigerants
Because many alternative low-GWP refrigerants are flammable, the evolution of the regulation governing these refrigerants is an issue that gives rise to many debates and initiatives.
US senators introduce bill to phase down HFCs
Thirty-two US Senators — 16 from each party — have cosponsored a bill to phase down HFCs and authorize EPA to facilitate transitions to next generation refrigerant technologies.
Cooling the world’s largest supercomputers
Direct liquid cooling is a highly energy-efficient solution for cooling supercomputers capable of performing millions or billions of billions of calculations per second. Here are two examples in the United States and France.
Publication of EU eco-design regulations for commercial refrigeration appliances
The Ecodesign regulations setting energy efficiency requirements for commercial appliances will apply in all 28 EU member states from March 2021.
The environmental benefits of evaporative cooling
An Eurovent study shows that evaporative cooling could help save up to 56,000 tons of CO2 emissions per year in the future in the European Union. Evaporative cooling is present in half of the projects presented by the eight Global Cooling Prize...
Singapore experiments with outdoor air thermoelectric cooling
In Singapore, the terrace of a riverside restaurant and children play areas are now cooled by a solid-state thermoelectric cooling technology.
Visualization of artificial proteins with cryo-electron microscopy
A team of researchers managed to visualize the atomic structure of peptoids.
