Abstract,IOP Publishing, 2018 With the overall temperature rise across the globe and the sweltering heat these summers, one can safely assume that households will see a furious shoot-up in their electricity bills this year. While the urban population resorts to air-conditioning to escape the heat...
- A variety of solutions have entered the market in recent years, which provide low-income households and workshops or small factories with a simple cooling solution that can be installed in a wall or window, basically providing them with a natural ‘air-conditioning’ system with no or low energy...

Access Agricuture Training Video When you pick your tomatoes, if you want to keep them longer, you have to find a way of reducing the temperature. As availability of electricity at village level can be a problem, ways have to be found to lower the temperature of this fragile crop. Some farmers at...

With an increasing interest in the use of refrigerants with a low global warming potential (GWP), engineers are looking to nature’s refrigerant – R-718, better known by its chemical formula, H2O. Evaporative cooling is not a new concept; its use in buildings can be traced back thousands of years....

01-01-1982 The results, as in previous years, revealed that summer planting of the greenhouses required a high input and resulted in a low out production. Considerable effort, time and investment must be spent towards research to increase the greenhouse cooling efficiency and plant productivity and in...
