Rooftop climate control technology: Lennox Evio reaches new heights

A rooftop climate control system is an easy and simple way of providing air-conditioning: an all-in-one unit with plug-and-play installation. As an economic, environmental-friendly, and highly adaptable system, the exciting new Lennox Evio takes this concept to new levels. It represents a sustainable and responsible rooftop solution that will provide years of energy-efficient performance in buildings that include shopping malls, food retail premises, restaurants, and logistics and storage facilities.

 

Modularity and flexibility

As visitors to Stand 9 U29 at MCE 2024 will discover, central to the advantages of this modular product is its great flexibility between airflow range and power capacity, providing the optimal solution for a wide range of building types and applications. All the air flow configuration a customer could want - regarding supply, return, exhaust and fresh air - is available. In fact, the new Lennox Evio offers improved supply air flow up to 49,500 m3/h. Further improvements include wider outdoor operating limits from -19°C to +48°C, and better thermal and acoustic insulation via a 50 mm thick double-skin panel of injected PU foam.

 

Seasonal efficiency exceeds Ecodesign Directive requirements.

With sH up to 168% and sC up to 207%, the new Evio rooftop systems exceed by far the seasonal efficiency requirements (SCOP 125%/ SEER 138%) of the Ecodesign Directive.  

 

A major benefit of the high-performance Lennox Evio is energy-efficiency, driven by several advances that include a new electronic expansion valve, a multi-scroll tandem compressor and  full EC fan motor technology for variable airflow control. As a result, this high-capability rooftop system offers eye-catching seasonal efficiencies in both cooling and heating (up to A+). For cooling, a new hydrophilic coil helps ensure an impressive 27% rise in SEER (average across the range) compared with the existing Lennox eBaltic rooftop system, while for heating SCOP is up 18%. 
 

 

“We have performed TCO [total cost of ownership] calculations comparing models of the same thermal capacity,” says Aurélie Pages,  Marketing Senior Manager at Lennox EMEA. “Operating 24/7 for 15 years in a climate such as France, users of the Evio can expect to save up to €35,800 [model dependent] in energy costs” , she continues. 

 

Reduced CO2 footprint

Reduced energy consumption of course contributes to low CO2 footprint, with further support arriving from the use of R32 refrigerant. This low-charge (30% less), low-GWP (Global Warming Potential), Pfas-free refrigerant is safe for both the environment and people. In combination, Lennox EMEA proprietary coil technology and R32 refrigerant means the new rooftop range has a very limited CO2 footprint, with validation provided by environmental protection organisation PEP Eco passport. 
 

Intuitive Control

To ensure ultimate comfort at the touch of a button, the Lennox Evio features a modern user interface for total control of the building’s climate. Newly available options for the eCLIMATIC controller include an attractive 7” touchscreen multi-unit display and a service web HMI (human-machine interface) in support of easier commissioning and maintenance.



 

Available in improved cooling and heating capacities of 25-250 kW, the Lennox Evio comes in various circuit/coil concepts based on a different combination of compressors and indoor/outdoor fans to suit the application. Lennox EMEA will have a team of experts available at MCE 2024 to discuss any applications or challenges.
