United States: latest news on HFC regulations
The US Court of Appeals for the District of Columbia has restored restrictions on the transition from ozone-depleting substances to high GWP HFCs.
IIR Statement: The essential role of refrigeration in the combat against COVID-19
Statement of the International Institute of Refrigeration calling governments to consider refrigeration-related services as “essential services” in the context of the current health crisis due to COVID-19.
Kenyan fish processing facility upgrades from R22 to ammonia
East Africa Sea Foods (EASF), a fish processing facility in Kenya, recently replaced its aging R22 refrigeration system with a two-stage ammonia system.
COVID-19 news in the HVAC&R sector
The IIR reviews the available information on the possible impact of air conditioning on the spread of COVID-19 and the recommendations for the operation and maintenance of HVAC systems. Furthermore, several...
Renewable energy consumption for heating and cooling in the EU
Over one fifth of energy used for heating and cooling from renewable sources in the EU.
China to enforce a more stringent energy efficiency standard for air conditioners
A new standard, which will come into effect on July 1, 2020, increases the minimum energy efficiency values of room air conditioners, resulting in the elimination of the least efficient air conditioners, i.e....
Viability of an absorption solar cooling system in an isolated school in Mexico
A recent IJR article presents a simulation of the operating strategies and the results of the first experiments following the installation of a solar thermal absorption air conditioning system, installed in an...
Reducing the environmental impact of ultra-low temperature refrigeration systems
Ultra-low temperature (ULT) refrigeration systems often use very high-GWP HFCs. Yet, ULT systems are excluded from the scope of the regulations aimed at phasing-down HFCs. An IJR paper reviews the most promising...
The EU is on track for meeting its HFC phase-down obligation
Latest official figures show that in 2018, EU-wide placing on the market of HFCs was 1% below the 2018 maximum limit set by the quota system, despite a 41% reduction of this limit compared with 2017.
World air-conditioning market in 2019
Despite a decline of -0.8% in sales globally, many markets performed well in 2019. Inverter technology and smart air conditioners are steadily gaining ground globally while sales of R32 systems are increasing...
Cool like a butterfly wing
New study demonstrates that butterfly wings contain a network of living cells with specific thermodynamic and thermoregulatory properties. Butterfly wings cool down as a result of low solar absorption combined with efficient radiative heat...
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.
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...
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.
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.
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.
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.
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.
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...
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.
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.
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.
