Engineering Principles, Modelling and Economics of Evaporative Coolers covers the basic engineering and technical principles behind the operation and construction of evaporative coolers, also highlighting challenges. The book presents the reader with selected case studies on modelling in the cooling chamber and explains the economic implications an evaporative structure can bring. Edited by a team of specialists, the book also explains the strong dependence of the technology’s performance on environmental conditions, and hence the limits on temperature control in the preservation of post-harvest agriculture products.

Evaporative coolers are an ancient technology, invented long before the introduction of chemical refrigerants as used in modern fridges or cooling towers. This two volume set covers the topic, with practical applications, construction techniques, and operation of the technology.

1. Evaporative coolant structure as a sustainable storage structure for extending the shelf life of food produce

2. Historic use of evaporative coolant structures by continent

3. Modern cooling and its advantages and disadvantages: A review

4. Theoretical design principles and practice of evaporative cooler

5. Evaporative cooling principles: Direct, indirect, indirect air cooling, and direct evaporative cooling

6. Evaporative coolant structure as an alternative to cold storage or controlled atmosphere storage for the preservation of fruits and vegetables

7. Construction of different types of evaporative coolant structure for preservation of fruits and vegetables

8. Zero-energy evaporative cooling technology and the prospective for fresh produce postharvest handling most especially for the preservation of fruits and vegetable

9. Application of natural material such as charcoal in evaporative coolant structure

10. The challenges and solutions to corrosion and other forms of construction material degradation in evaporative cooling structures

11. Recent advances in the application of sensors used in evaporative coolers to monitor chamber environmental parameter

12. Alternative energy sources that could be utilized in the operation of evaporative coolant structures most especially in rural communities

13. Edible coatings and evaporative cooling best practice guidelines for extension of preservation of fruits and vegetables

14. Computational fluid dynamics (CFD) analysis of airflow inside an evaporative cooler for storage of fruits and vegetables

15. Socio-economic aspect of evaporative coolant structure

16. Role of government and policymakers towards supporting the deployment of evaporative coolant structure

17. Renewable energy integration into a low-cost evaporative cooling system for fresh produce storage

18. Numerical and experimental investigation of the potential of combining evaporative cooler with a CoolBot air conditioner for a low-cost tomato cold storage

19. Application of computational fluid dynamics modelling for coolers

20. The influences of different cold storage environments on the mechanical and physiological quality of stored amadumbe (Colocasia esculenta L. Schott)

21. Development of evaporative coolers over time
