SERVICE AND MAINTENANCE


Preparing for summer


Maintenance engineers and installers are responsible for ensuring air conditioning equipment operates at its optimum during the summer months when it is most needed. The question is how? John Grenville, managing director of ECEX, has the answer.


A


s summer approaches, it is time to think about how the change of season will impact on heating, ventilation and air conditioning (HVAC) systems – especially the VAC part – and what needs to be done to ensure they continues to operate at their optimum. There are, essentially, two factors to consider – maintenance and protecting the equipment from airborne detritus such as pollen. Maintenance is innately linked to energy efficiency in HVAC systems, and implementing it

effectively pays real dividends in terms of fewer breakdowns, better efficiency and a healthier bottom line. Indeed, it is the most cost-effective way to ensure reliability, safety, and energy efficiency in HVAC plant and equipment. Sadly though, too often, maintenance is viewed as an overhead that can be cut. This sort of thinking leads to reactive maintenance with no schedule in place, only a reaction to breakdowns, or, worse, no maintenance at all.


There are essentially two forms of pre-emptive


maintenance used for HVAC equipment – preventive and predictive. Preventive is scheduled maintenance, usually based on manufacturer guidelines.


However, predictive maintenance is the most cost-effective approach in terms of limiting breakdowns and reducing energy consumption. Schedules are based on the actual equipment and the environment in which they operate. Predictive maintenance involves monitoring the condition of equipment using tools such
