Using CO2 as a refrigerant gas can reduce energy consumption and increase cool room efficiency. Refrigeration plant is generally a mature technology. Several refrigerants are in common use including R22 (being phased out due to its ozone depleting potential), R134a and R404a. Although the refrigerants R134a and R404a do not significantly affect ozone depletion they have [...]

Good irrigation system design and maintenance has the potential to both lift productivity and reduce energy costs. Distribution uniformity (DU) is a measure of how evenly an irrigation system applies water. Low DU means that some parts of the crop are too wet while others are under-watered. Many growers compensate by irrigating to satisfy the [...]
