Energy Efficiency Technologies – Air Source Heat Pump vs. Ground Source Heat Pump
Journal of Sustainable Development, 2009 Heat pump deserves the name of eco-innovation. It uses ‘free energy’ - warmth collected in the soil or in the air to provide heat ing and cooling. There are two main types of heat pumps – air source heat pump and ground source heat pump. How do they work? What are the benefits of each system? How do they compare?

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres
Advanced Engineering Materials, EarlyView.This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.
