What was a key design change for HFC-134a AC systems versus CFC-12 AC systems?
A key design change for HFC-134a AC systems compared to CFC-12 systems was the need for different materials and components to accommodate the properties of HFC-134a. HFC-134a operates at higher pressures than CFC-12, necessitating stronger hoses, seals, and components to prevent leaks and ensure reliability. Additionally, the lubricant used in HFC-134a systems had to be changed from mineral oil, typically used with CFC-12, to synthetic oils that are compatible with the new refrigerant.

How do you develop systems to involve stakeholders in the planning of change in an organisation?
To develop systems for involving stakeholders in organizational change planning, start by identifying key stakeholders and their interests. Facilitate open communication through regular meetings, surveys, and feedback channels to gather input and address concerns. Create collaborative workshops to co-design solutions, ensuring stakeholders feel valued and engaged in the process. Finally, establish clear roles and responsibilities to maintain accountability and enhance stakeholder commitment throughout the change initiative.
