Closed Loop System Calculations

I need precise calculations for a closed loop humidification and dehumidification system designed to process approximately 200 liters of water. The focus of this project is optimization of equipment and pipes sizes. The system will operate with minimal automation, so solutions must prioritize simplicity and manual controls where appropriate.
