To comply with the Australian requirements, the Rosemount Hotel had an evaporative type air conditioning system which used to work well to cool their main function room during the busy summer months. The system works primarily by bringing 100% fresh air from outside, which is cooled and delivered via duct work into the establishment, forcing warm stale air out through normally open doors and windows maintaining a balanced temperature.
On the other hand, by keeping doors and windows open, the pub became a problem in the neighbourhood because of the constant noise produced by music and revellers. The quick fix: keep the doors shut.
The solution didn't work quite as well as they had hoped as the flow of fresh cool air was now stifled. The lack of air circulation and warmer room temperature would cause a very uncomfortable environment for staff and customers.
Worried about the wellbeing of the clientele, the Rosemount management team engaged Eco Climate Solutions to design a better solution to the problem as the doors would need to keep closed during operation.
"We redesigned the small and ineffective exhaust fan and duct work system to incorporate a larger and better-designed effective solution. In our new design, the exhaust air system would extract 90% of the supply air to allow sufficient airflow to cool the room even with the doors closed" explains Gareth Halliday, ECS General Manager.
To make it more energy efficient, the ECS team installed a Variable Speed Drive (VSD) on the unit. Which once fully commissioned would enable them to achieve the exact air volume required in both low and high speed fan settings.
As a result, not only the Rosemount Hostel customers were happy, but also the management team who have now engaged Eco Climate Solutions for complete servicing of the refrigeration and mechanical services to make sure Summer days are what it should be: only hot enough to enjoy a cold beer.
