Airedale International Air Conditioning has launched a range of chilled water systems which it claims outperform rival products in terms of cooling capacity for footprint and energy efficiency ratio (EER).
Available in capacities from 11 to 233kW, the SmartCoo SD, SN & SR range has been designed to maximise the use of the internal heat exchange area in addition to other energy efficient enhancements, according to the company.
The new frame design on the SmartCool SD (60kW–233kW) facilitates a larger coil area and improved airflow path. The innovative slab coil arrangement, with filters located on the face of the coil, provides up to 15% more surface area for air flow and allows for low air-side pressure drop, increasing efficiency by lowering fan power. Energy efficiency in the SD model is further increased by locating the fans in the floor void.
The SmartCool SD is also designed with two fully modulating, two-way actuated ball valves in place of a single three-way valve. In addition to improved efficiency, this brings further benefits as the two-way valve method of controlling the chilled water can be used as an auto-commissioning tool saving commissioning time.
Airedale’s SmartCool SN/SR models (11kW–60kW) are designed with innovative V-frame heat exchangers, again improving air flow through the unit and reducing pressure, to deliver market-leading efficiency levels and consistently outperform rival systems.
All units incorporate the latest release in fan technology. The backward-curved centrifugal EC fans are up to 70% more efficient than their AC equivalents and allow units to be configured to customer needs according to whether they require high airflow/high capacity or low airflow/ high efficiency. This makes units extremely competitive when considering both cooling capacity per footprint and efficiency. The aerodynamic design of the fans also helps reduce noise, according to Airedale.
