Evaporative cooling: continuation of the Cold-Snap project at Harvard University
Tests show that Cold-Snap evaporative cooling technology would be effective in humid climates, while limiting water consumption.
Evaporative cooling without adding humidity
Scientists at the University of Harvard have designed a prototype evaporative cooling system called Cold-SNAP that effectively cools air at low cost for both dry and humid climates.
Passive cooling by combining evaporation, radiation and insulation
ICER, a new passive cooling technique, can extend food shelf life by 40% in humid climates and 200% in dry climates with low water-refilling frequences.
Efficient cooling methods to reduce heat stress in pigs
Microclimate parameters such as air temperature and humidity are important indicators of animal welfare. Besides, heat stress is more detrimental to productivity in the swine...
R&D
The US Department of Energy's National Renewable Energy Laboratory (NREL) has developed a new air-conditioning system combining membranes, evaporative coolers and desiccants into a single device with the objective to suit to all climates,...
New evaporative cooling system for more energy efficient data centres
A dew point cooling system, which is an indirect evaporative cooling system that approaches the dew point, has reduced the electricity consumption of a UK data centre by 80%.
Energy saving initiatives for cooling in data centres
In January 2021, Europe’s leading cloud and data centre operators signed the Climate Neutral Data Centre Pact, a self-regulatory initiative to become climate neutral by 2030. According to recent studies, free...
Green roofs can reduce cooling demand in warm climate zones
The impact of green roofs on building energy performance was assessed in 15 climate zones. In most regions, the reduction in energy demand for cooling was greater than for...
The Pentagon activates solar air conditioning
The solar heating, air-conditioning, power and lighting system installed at the guard station of the Pentagon is one of the most advanced in the US. The system incorporates 12 advanced ways of using solar energy to reduce fossil and electrical...
Japanese households don’t make the most of reversible heat pumps
Despite a high market penetration, less than half of Japanese households use their reversible heat pumps for heating.
Briefs: Open units or with glass doors?
When glass doors are used in refrigeration units, the energy savings are as a rule indicated as being "up to" 40%. Very often these figures are based on experience in a typical climate (25°C and 60% air humidity) with standard opening frequencies...
Climate control for your desk
We are used to taking command of our personal climate in planes and cars by using simple controls. Why not in buildings too? A study of the effect of installing individual air-conditioning vents at office desks, and putting controls at each...
