UNEP looks to the sea for a cool change in Egypt
The International Energy Agency states that cooling technology creates more than 7 per cent of the world’s greenhouse gas emissions. In Egypt during summer, approximately half of the country’s electricity goes towards air conditioning. Temperatures can hit 40°C and remain in the high thirties throughout the season, especially in cities experiencing the urban heat island […]

Humidity a major factor in emissions from cooling
Scientists from the National Renewable Energy Laboratory (NREL) and Xerox PARC have released a study exploring the environmental impact of controlling humidity. The research first appeared in the journal Joule, titled “Humidity’s impact on greenhouse gas emissions from air conditioning”. While studies on air conditioners and greenhouse gases have been compiled before, this is the […]

Daikin releases AirHub Touch Zone Controller
Designed in Australia, Daikin’s AirHub Touch Zone Controller has been developed to give homeowners more flexible temperature control. “With the typical home divided into separate areas or ‘zones’,” says Daikin, “it makes sense to only air condition zones that are occupied, and switch off unoccupied zones. When used in conjunction with a Daikin Premium Inverter […]

Cooling demand set to rise along with temperatures
A recent study by Empa researchers has predicted that climate change could increase the cooling demand of buildings. The projection is based on climate data from Switzerland and research done at NEST, a building Empa and Eawag use for modular research. It is estimated that the average global temperatures will rise due to climate change, […]

Whitest ever paint promises cooling benefits
A team of engineers at Purdue University has created the whitest paint in history and says that using it on buildings may help cool them down, reducing the need for air conditioning. The research team created an ultra-white paint last year, but have since improved the formula. Purdue professor of mechanical engineering, Xiulin Ruan, told […]

AHRI releases A2L report for firefighters
The US-based Air Conditioning, Heating and Refrigeration Institute (AHRI) has released a test report that examines fire safety issues related to A2L (lower flammability) refrigerants. The fire service requested that data be developed to identify hazards to fire service personnel when responding to fire events in occupancies with the new refrigerants. Undertaken in cooperation with […]

Ducted vent solution to prevent heat leakage
Australian inventor Dean McGurgan, Affil.AIRAH, has developed a ducted ceiling vent that he claims can save on all forms of household heating loss from all types of ducted air conditioning systems – without the need for wires, batteries or apps. Pending a licensing deal, McGurgan calls the as-yet unnamed product an “anti-gravity ducted ceiling vent”. […]

Study on spread of COVID-19 in air conditioned bus
The coronavirus could be transmitted over a longer distance than previously thought, especially within an enclosed air conditioned environment, according to a study by a team of Chinese government epidemiologists. The research by the Hunan-based team throws into question the official guidelines from China’s health authorities on COVID-19 prevention to keep “a safe distance” of […]

Hitachi introduces FrostWash Technology
In response to what it perceived as an unmet need for greater cleanliness in air conditioning systems, Hitachi has introduced “FrostWash Technology”. “Air is always travelling across the surface of the heat exchanger,” says Hitachi. “Dust, mould and bacteria can accumulate, leading to reduced performance and perceivable odours. Keeping the heat exchanger clean is the […]
