Sustainable low-enthalpy air conditioning for greenhouse

For achieving the objectives:
goal 7
goal 13
Goals: 7. Affordable and clean energy, 12. Resp. consumption/production, 13. Climate action

Description

ENEA has developed a sustainable low-enthalpy air conditioning system for greenhouse cooling/heating. Heating occurs through radiant heating tubes which can be coupled to heat pumps.

The system can exploit the near-surface geothermal sources, small-depth and low-temperature (<100°C) ones, available in some geographical areas such as Kenya, Uganda, Tanzania and Ethiopia.

An alternative supply can be warm wastewater deriving from industrial processes that can be recycled in a circular economy perspective.

Such technology can be transferred and adjusted to meet the needs of developing countries.

Benefits and Advantages:

  • Greenhouse production with low environmental impact
  • Use of renewable energy sources
  • Lower fossil fuel energy consumption and reduction of carbon dioxide emissions
  • Continuous crop cycles
  • Cost-effectiveness
  • Lower thermal pollution from geothermal water and/or warm industrial wastewater

ENEA Service:

  • Technology transfer
  • Technical support
  • Consulting
  • Training
  • Design
