The Eurovent Certified Performance (ECP) programme scope for Heat Exchangers (HE), covers five groups of products used for refrigeration and process cooling, using axial flow fans. These include Direct Expansion (Dx) Air Coolers using HFC, Dx Air Coolers using CO2, Air Cooled Condensers, CO2 Gas Coolers and Dry Coolers.
Programme exclusions can be found in the Technical Certification Rules.
Whenever a company participates in the programme for Heat Exchangers, all applicable products that are promoted by the applicant/participant, are certified. This is done in accordance with the Technical Certification Rules and includes all models in modular ranges. For the HE programme, the certify-all requirement is applicable not only to the European market but worldwide also, and is defined in the Certification Manual.
The products below are used in refrigeration and process cooling applications for buildings.
Air coolers are a refrigeration system component, which transfers heat from air to a refrigerant, or liquid. Air coolers typically consist of a heat exchanger, fan(s) and casing. The coil is normally of fin and tube or microchannel construction.
Also known as air evaporators, air coolers allow the refrigerant to move from the "liquid" state to the "gaseous" state by heat transfer via forced air convection. Air is blown or drawn across the heat exchanger fins at a temperature higher than the refrigerant within the coil. As the refrigerant absorbs heat from the air, it evaporates. The movement of heat to the refrigerant in the coil, cools the outside air.
Air coolers can come in a range of sizes and designs. The heat exchanger can be built using a number of different materials such as copper and aluminium, and include specialist coatings. Air coolers can also operate using a wide range of refrigerants. Fans are an important component when it comes to energy use and can utilise AC or EC motors. Air coolers for refrigeration are commonly used in buildings for commercial and industrial cold room applications.
In the HE programme, two types of air coolers are certified. You’ll find them under the product types Air Coolers CO2 (air cooler using CO2 as refrigerant) and Air Coolers HFC (air cooler using HFC refrigerants).
Condensers are a refrigeration system component that condenses refrigerant vapour by rejecting heat to air mechanically. Condensers will typically consist of a heat exchanger, fan(s) and casing.
Condensers allow the refrigerant to move from the "gaseous" state to the "liquid" state by cooling it via forced air convection. Air is blown or drawn across the heat exchanger fins at a temperature lower than the hot refrigerant gas within the coil. As the refrigerant releases heat to the surrounding air it condenses back to a liquid.
Condensers typically use fin and tube or microchannel heat exchangers, and can come in a range of sizes and designs. Fans can utilise AC or EC motors. The heat exchanger can be built using a number of different materials such as copper and aluminium, and include specialist coatings. Condensers are designed to be installed outdoors as they expel heat to the ambient air. They are primarily installed in buildings, in chilled water production units and can be used for process cooling or refrigeration.
In the HE programme, two types of condensers are certified - Air Cooled Condensers (using HFC) and CO2 Gas Coolers (using CO2).
Dry coolers are a refrigeration system component that cools liquid by rejecting heat to air mechanically. Dry coolers will typically consist of a heat exchanger, fan(s) and casing.
Dry coolers are heat transfer devices that cool water, or water glycol mix, used in a closed circuit by forced air convection. Air is blown or drawn over a heat exchanger, which can either be a traditional fin and tube design or microchannel. The air passing over the heat exchanger fins attracts heat from the water / water glycol mix within. Once cooled, the fluid is ready to absorb heat from an associated process.
Dry Coolers are designed to be installed outdoors and are suitable for buildings with high cooling capacities. They can be used to cool the water in the water condensers of chilled water production units, or for free cooling applications.
While exploring our certified products you’ll come across a number of technical terms relating to certification. The below definitions help explain the search criteria in our certified product directory.
All certified product types in the HE programme have the following search criteria in common :
Brand
Brand name of the manufacturer.
Range
Listing of models with some common features.
Model
Model name.
Energy ratio
The certified nominal capacity in kW, divided by the total certified power input of the fan motors in kW, at the standard rating condition. The higher the energy ratio, the more energy efficient the product.
Surface Area
Surface area of the heat exchanger is the total area through which the heat exchange takes place and is expressed in m2. In fin and tube heat exchangers this includes the surface area of both tubes and fins. For microchannel this includes the air side heat transfer surface, fin surface and flat tube air-side surface.
Energy Class
This is the Energy Class the product sits within. For Eurovent energy classification, E is the lowest energy class rating while A+ the highest.
Refrigerant
Refers to the type of refrigerant the product uses.
No. of fans
Number of fans the product uses.
Fin spacing
The space between the heat exchanger fins in mm.
SC
Stands for standard condition.
Standard capacity
Is the cooling capacity for standard temperature conditions.
Nominal capacity
Shows the standard capacity multiplied by a fixed ratio (refrigerant correction factor). The correction factors help to compare between the real performances of the unit with the standard performances (measured in standard conditions).
Pc
Is the cooling capacity (in kW). It is the total heat flow rejected by the liquid (for dry coolers, condensers and CO2 gas coolers) or by air (for air coolers) at standard temperature conditions.
Pe
Shows fan power consumption (in W). It is the electric power absorbed by the fan motor.
Qv
Is the air flow rate (in m3/h). It is the quantity of air blown by fans through the coil of the heat exchanger, to cool down the refrigerant. Air flow is measured with dry and clean air.
Lp @10m
Means A-weighted sound pressure level. It measures the level of noise produced by the unit at a 10-metre distance in a free-field environment, expressed in decibels and weighted in accordance with standardised procedures.
Lw
Means A-weighted sound power level at a set speed. It measures the total airborne sound energy radiated by the unit, expressed in decibels and weighted in accordance with standardised procedures.
DPw
Means liquid side pressure drop (only for liquids).
