Air handling units

• Key facts

 6 classes from A to <E: complex interrelationships to evaluate the energy efficiency of AHU, can even depend on climate conditions

 One letter to represent balanced effects of:

• Air velocity in the fan section (v)

• Heat recovery efficiency (η) and pressure drop (Δp) • Fan efficiency (f)

 3 subgroup of products:

• Design outdoor temperature < 9°C (HRS will significantly save energy) • Design outdoor T > 9°C : N

• Single supply / extract units : h

Cooling Tower Certification

Started Feb,2012

22/30 _{March 2013}

Cooling Tower Certification for

Open

Circuit

& soon to announce inclusion of

Closed Circuit

• The importance of air conditioning and

industrial cooling is constantly increasing in modern architecture and industrial process cooling.

• The human perception of comfort and the new challenges to reduce the electrical power consumption and CO2 footprint

have designers striving for optimal system performances with the highest possible efficiencies. Reliable thermal

performances are crucial to ensure these

best efficiencies which are typical for cooling circuits driven by evaporative cooling

equipment.

• Eurovent Certification Company guarantees the consistency of thermal testing and

manufacturing of European and

non-European companies that subscribe to the program.

Summary

Key benefits in one glance

• Easy product selection in HVAC-R

 Direct comparison of competitive products

• Good for customer, good for the planet

 New installations as well as retrofitting

 Less energy consumption as the unit runs as expected to achieve the required performance ⇒ reduced product climate and environmental impact as well as electricity costs

 Possible Incentives for more energy savings?

• In all cases, the best practice:

Good design (avoid oversizing)

⇒ ask for third party certified performances

Good energy efficiency

⇒ ask for third party certified best classes

Formula For Success:

Certified efficient

products

,

Optimized system designs, &

Professional installations

Some key issues:

• Air Re-circulation

• Noise Amplification

• Control Strategy

• Poor Installation

• Regular Maintenance
