Powerful compressors drive cooling research

GEA Grasso screw compressors for the compression of helium gas are playing a crucial role in one of the world’s largest construction projects for cutting-edge international research. The compressors are part of the FAIR (Facility for Antiproton and Ion Research) particle accelerator facility for cooling superconducting magnets. The order placed…

Responsible Refrigeration No 81

Continuing on from the previous column dealing with the Certificates of Conformity via the online APP. The online app can be downloaded from the Play Store using a tablet or smart phone. Search for the SAQCC Gas CoC and proceed with install. You will asked if are you are registered…

Responsible Refrigeration No 80

The introduction of an online Certificate of Conformance (CoC) for both Android and iOS platforms has resulted in the paper CoC in book form being stopped. The CoC books are no longer available. A CoC can only be issued via the online format. The online app can be downloaded from…

Building HVAC and PV-powered thermoelectric cooling

Scientists have proposed a way to combine thermoelectric modules (TEMs) with rooftop PV to support HVAC function in buildings. They designed a wall-integrated TEM to heat and cool adjacent rooms. An Australian-Indian research group has looked at how thermoelectric modules (TEMs) and PV could be combined to provide heating, ventilation and air…

A Breath of Fresh Air—Necessity, Not Luxury

Picture yourself in a building with minimal windows, vents, doors, and other openings. There is no movement at all in the stale and dense air. Feeling uncomfortable yet? While some may say you could endure this environment at home, work or in public spaces, this is not simply a bit…

Debate on air conditioning as a basic right

Is access to cool air a human right in today’s environments? Canada is debating the question, and climate activists aren’t the only ones pressing the issue. A coalition representing private and public sector interests – including insurance companies, the Canadian Chamber of Commerce, the Federation of Canadian Municipalities and the…

Boost for sustainable cooling in Africa

The new funding secures work at the Africa Centre of Excellence for Sustainable Cooling and Cold Chain (ACES) in Rwanda until 2025. ACES was established in 2020 by the governments of the UK and Rwanda, the Centre for Sustainable Cooling, the United Nations Environment Programme’s United for Efficiency initiative and…

Responsible Refrigeration No 79

Training on the new SARACCA training manual introduced at the beginning of 2022 provides an understanding of the Pressure Equipment Regulations, SABS standards and good engineering practice in refrigeration. while the use of the F-gases continues through the phase-out of HCFC and HFC’s refrigerants the appearance of flammable refrigerants has…

Indoor CO2 tool can help assess ventilation and indoor air quality

A key ingredient for good indoor air quality is good ventilation. One simple method that can be used to determine if a space is well ventilated is to measure indoor carbon dioxide (CO2) levels. This greenhouse gas drifts through more than just our skies. CO2 can be found in the buildings…

New long-term method to store renewable energy with a chemical heat storage system

On July 22, 2022, Posted by , In News, By ,, , With No Comments

Renewable energy requires long-term storage options. A chemical heat storage system has been invented at the Vienna University of Technology that could bring surplus energy from summer to winter. Rising global energy demand and climate change make the phase-out of fossil fuels inevitable – and current geopolitical developments call for…
