Who are we?Introduction to Europe’s Industry Association forIndoor Climate, Process Cooling, and Food Cold Chain Technologies



• Eurovent is Europe’s Industry Association for Indoor Climate, Process Cooling, and Food Cold Chain Technologies – thinking beyond ‘HVAC&R’

• Members from 20+ countries in Europe, the CEE region and Northern Africa (EMENA)

• Strong network of EMEA’s leading, national industry associations and their more than 1.000 ‘Affiliated Manufacturers’

• Corresponding Members in countries without national association


Our Members and their ‘Affiliated Manufacturers’Our Members are leading national associations from the EMEA region…

And the more than 1.000 manufacturers within their networks (known as ‘Affiliated Manufacturers’ within Eurovent)

2016 Corporate Presentation

Our Corresponding Members

Manufacturers from EMEA countries, which do not yet have a national association Member within the Eurovent network.

Examples include:

2016 Corporate Presentation

Our Associate Members

ECC holds the EN ISO/IEC 17065:2012 accreditation certificate:

Eurovent Market Intelligence (EMI)

EMI provides reliable and representative HVAC&R market intelligence data based on information supplied by market participants.

Its EMEA-wide data sets are frequently being used to support the development of legislation in the EU and beyond.


How do we support our industry internationally?


Founding member of ICARHMA

• Founding member of ICARHMA, a global network of HVAC&R associations from Australia, China, Europe, Japan, Korea, Latin and North America

• Close partnerships with sister associations across the globe

• Representative of Europe within ICARHMA

What are Air Curtains?Introduction to Air Curtain technologies


What are Air Curtains?

An air curtain is a directionally-controlled airstream which can reduce the infiltration or transfer of air from one side of the opening to the other and/or inhibit the passage of insects, dust and debris


Possibilities with an open door

Air Curtains…

Attract visitors and customers

Provide for an uninterrupted vision

Enable easy mobility for people and vehicles

What are the key benefits of Air Curtains? The advantages of applying state-of-the-art Air Curtain technologies to your construction projects


Air CurtainsKey benefits

Without Air Curtain With Air Curtain Overall benefits


Air CurtainsKey benefits (cont.)• Building’s energy saving

• Climate division between an area or room and the outdoor air (no transfer of heat)

• Climate division between areas or rooms situated on both sides of an opening, cold rooms (no transfer of heat)

• Building’s Indoor Air Quality (IAQ)• Barrier inhibiting the transfer of pollution, odours and moisture from

one zone to the other

• Building’s Indoor Comfort

• Temperature, preserve and compensate losses


Air CurtainsBuilding’s energy saving

The Building’s energy saving depends on the air curtain Screening efficiency index SEI

SEI = 1 −𝑄𝑤𝑖𝑡ℎ

𝑄𝑤𝑖𝑡ℎ𝑜𝑢𝑡Qwith= Heat loss through an opening with an Air Curtain

Qwithout= Heat loss through an opening without an Air Curtain


The SEI describes how much heat is not loosed through a door opening by using an air curtain unit

International standards for Air CurtainsISO 27327: Fans, Air Curtain Units


ISO 27327-1Scope

This part of ISO 27327 establishes uniform methods for laboratory testing of air curtain units to determine aerodynamic performance in terms of airflow rate, outlet air velocity uniformity, power consumption and air velocity projection, for rating or guarantee purposes.


ISO 27327-1Test methods


ISO 27327-1Missing points

1. Standard Rating Conditions

2. Test Environment

3. Calculation formula/method in order to assess the buildings’ benefits by using Air Curtains

Cold storage temp: -23°CHeated area temp: +26 °CDoor dimensions: 2.4 x 2.1 m Door opened 100 times a day


• Huge energy losses • Temperature rise in the cold sections• Ice on the refrigeration units• Ice on the floor



• Lower cold losses• Frost free result• Easier to pass through the

door without the plastic strips



Without Air Curtain

Average cold room temperature: -15°C

With Air Curtain

Average cold room temperature: -19°C
