Beyond the Cooling Switch: Protecting the Ozone Layer Throughout Equipment Life

World Ozone Day: a practical workplace perspective

The environmental story of an air conditioner does not begin when someone switches it on. It begins with the purchase specification and continues through installation, servicing, replacement and final disposal.

World Ozone Day is an opportunity to examine that entire journey.

UNEP describes life-cycle refrigerant management as a coordinated approach to limiting refrigerant use and emissions throughout its life. For workplaces, this means connecting decisions that are often handled by separate departments.

Purchase with the future in mind

Procurement should consider more than purchase price and cooling capacity. Refrigerant characteristics, energy performance, operating conditions, maintenance capability and the availability of an appropriate recovery route all deserve attention.

Ask the supplier to identify the refrigerant and provide the equipment documentation. Confirm that local technicians can service the system safely and that suitable tools and spare parts are available.

An attractive quotation can become an expensive problem if the organisation lacks the capability to maintain the equipment.

Establish control at installation

Before acceptance, assign an asset identity and retain commissioning information, the refrigerant specification and maintenance requirements. Confirm that installation and testing were completed by competent personnel.

These records establish the starting point for future investigation. Without them, later teams may inherit equipment whose charge history, modifications and service needs are uncertain.

Maintain for reliability and efficiency

During operation, use the manufacturer's maintenance requirements and the equipment's condition to guide work. Record refrigerant movements and investigate recurring defects.

Refrigerant containment and energy efficiency address different aspects of environmental performance. Keeping refrigerant inside the system does not compensate for avoidable energy waste; efficient operation does not justify refrigerant releases.

A sound maintenance programme considers both.

Plan retirement before removal

End-of-life equipment may still contain refrigerant. Removing a unit from service should therefore include a recovery plan and a documented destination for the recovered material.

An illustrative example is the replacement of several office air conditioners. The purchase order should cover competent recovery and responsible equipment handling, with records demonstrating what was removed and where it went.

Decommissioning should not become an undocumented handover to whoever collects the scrap.

Connect the departments

Procurement, facilities, maintenance, HSSE and waste contractors each influence the outcome. Name the person responsible for keeping the full equipment history together.

For World Ozone Day, review one asset from purchase to retirement. Identify where information or responsibility disappears, then repair that gap.

Discussion question: Can we trace our cooling equipment from its purchase specification to its final refrigerant destination?
