Ecodesign Directive for HVAC Chillers and Heat Pumps

YORK Commitment: A European View

At Johnson Controls, we have been dedicated to protecting the environment since our invention of the electric thermostat in 1885, which provided a fundamental shift in the energy efficiency of buildings. Now, all over the world, our products and services empower customers and communities to consume less energy and conserve resources.

This commitment is in line with the targets of the European climate and energy package for the future.

03 YORK Commitment: A European View | 2020

EU Energy and Climate Policy ContextThe European 2050 Vision towards a low carbon economy is targeting reduction of 80/95% of the Green-house gas emissions by looking at the reduction of the 3 following parameters and comparing to the values of 1990.

EU Energy efficiency improvement targets strongly influence the HVAC market

Buildings are the largest consumers of energy today, and HVAC systems account for a significant portion of a building’s energy consumption. This is why the HVAC industry is a focus of European Environmental Policies. The F-Gas regulation addresses direct emissions while EPBD, EcoDesign and RES are directives focused on indirect greenhouse gas emissions by improving the efficiency of the HVAC systems and the buildings.

The Regulatory Response

What is Ecodesign Directive?

As stated on the previous graph, building energy consumption is ~40% of the overall total in Europe and the HVAC system consumes more than a third of the building energy total. So, as an estimate, the HVAC industry is responsible of 15% of the overall European energy consumption, That makes it a key driver to achieve the 2020, 2030 and 2050 targets. There are four main legislations focused on the HVAC industry:

Ecodesign Directive is a framework that regulates the environmental impact of all products using energy (excluding products in the transport sector). Application of Ecodesign Directive for Chillers and Heat Pumps is enforced through regulations specific to various products and operating ranges. Once a regulation is published and active, products affected must comply with the minimum efficiency performance, sound emissions, etc., to receive a CE mark.

As the word Ecodesign stands for, this regulation focuses on the design of the machine and implies taking into account all the environmental impacts of a product right from the earliest stage of design. It’s proven that around 80% of the environmental impact is determined at the design stage while the other 20% is related to the operation. Ecodesign is forcing manufacturers to renew the product range and create new and more efficient designs.

Ecodesign has changed the way we speak

Which products are affected by Ecodesign?


The European Union has developed two directives (Ecodesign Directive 2009/125/EC and Energy Labeling Directive 2010/30/EC) to address the environmental impact of all Energy related Products (ErP) beginning at the earliest stages of design. The Ecodesign directive affects all types of Energy related Products (ErP) such as TVs, washing machines, lights and, of course, also HVAC products and components. Energy related Products (ErP) are grouped into “Lots” that, once they are published, they become mandatory CE regulations. There are three Ecodesign Lots (already approved regulations) that directly impact HVAC products.

Each of the three regulations set the MEPS or Minimum Efficiency Performance Standards for the product category and those are implemented in 2 steps (Tiers), as shown in the table below.

According to the below chart, a same chiller model can be applied to different regulations and/or different temperature levels. When the application is known, the machine should comply with the requirements defined by Ecodesign for this specific application. If a product meets the requirements of any category, it is enough to get the CE mark as the model can be used at the different applications.

Former full efficiency ratios at full load like EER and COP are being used less and less. Even the former seasonal efficiency ratio ESEER has been replaced. Ecodesign MEPS are the current key indicators used for all HVAC product and compliance is mandatory to have the CE marking. The Eurovent organization is already using Ecodesign MEPS at the different certification programs and not using their former ESEER values anymore.

SEER

Ecodesign regulation 2016/2281 affects Comfort Cooling Chillers with rated cooling capacity below 2,000 kW with a leaving chilled water temperature equal to or higher than 2°C. It’s divided into two sub-categories (low and medium T) based on the chiller water temperature. The MEPS that apply in each of the two Tiers are the same independently of the T sub-category used. Manufacturers must provide a technical data sheet, called Product Fiche, with the equipment to detail the application(s) in compliance.

Calculation methodAn important point that must be specified on the manufacturers rating report is the calculation method regarding the water flow and outlet temperature. According to the regulation there are four possible methods.

Comfort Chillers used at low temperatureChillers that provide water to fan coil or air handling units using 12 to 7°C as entering and leaving temperatures for the efficiency calculation.

Comfort Chillers used at medium temperatureChillers that provide water, for instance to cooling floors or chilled beams, using 23 to 18°C as entering and leaving temperatures for the efficiency calculation.

SEER - Seasonal Energy Efficiency Ratio

Ecodesign regulation introduces new Minimum Energy Performance Standards for Comfort Cooling Chillers (SEER) that it’s the ratio between the annual cooling demand and the annual electrical input energy over the entire cooling season.

SEER is calculated using standard EN14825, which takes the following into account:• Seasonal efficiency while the unit is operating (SEERon). It considers all the energy consumptions during ON mode (compressor, fans, auxiliaries) and takes also into account the heat exchanger pressure drops.

• Electrical consumption when the compressor is not running: crankcase heater, standby or OFF mode

SEER is a better performance indicators for cooling than former ESEER, as it takes into account temperature bins and hours based on weather data from a reference city (Strasbourg) and for a comfort cooling application.

• Variable Outlet increases the leaving water temperature at partial load. This reduces the lift required by the chiller, reducing energy use significantly. To provide this rating, chillers must be capable of automatic water temperature reset based on outdoor ambient temperature. With this capability, even projects without advanced building control systems can benefit. Variable Outlet Temperature (VO) is only available for chillers at low temperature, while those at medium temperature use a Fixed Outlet Temperature (FO) of 18°C.

• Variable Flow reduces energy use at part load through reduced waterside pressure drop and water pump power input. Variable Speed Pumps must be fitted to the system to benefit from this savings.

• It is important to note that efficiencies can vary hugely depending on the temperatures and the method of calculation.

• It is crucial to check the chilled water conditions used to determine the SEER when comparing the seasonal energy efficiency of chillers.

Efficiency requirements set by REGULATION 2016/2281 Comfort Cooling

Regulation 2016/2281 sets seasonal energy efficiency in ηs,c. This value expresses SEER in terms of primary energy and makes it possible to compare the energy efficiency of units using different energy sources. In Europe, on average 2.5 kW of primary energy is required to generate 1kW of electricity and therefore the next formulas and values are used for the conversion.

Design points for Comfort Cooling

The regulation requires calculating the part load efficiencies at A, B, C, D rating points as per below table. For the rest of the temperatures covered by the regulation, the values are calculated using an interpolation and extrapolation process. Each point is weigthed by the BIN hours defined by the standard. Please refer to the calculation example for a better understanding (page 14).

No cooling efficiency requirement is defined by Ecodesign for heat pumps (regulation 813/2011) or for medium temperature industrial or for process chillers (regulation 2015/1095).

(*) Temperatures dependent on water flow rate as determined at standard rating conditions.(**) Entering condenser water decreases to 18°C at partial load. Together with Variable Outlet reset to 11.5°C, the chiller can operate at very low lift for outstanding energy efficiency. Only the most advanced chillers can operate at this condition today. If this condition cannot be achieved, Ecodesign standard permits rating at highest leaving evaporator water temperature possible, typically 8-10°C (depending on technology).

Medium TemperatureRegulation 2015/1095

High TemperatureRegulation 2016/2281

Ecodesign regulation 2016/2281 also applies to High Temperature Process Chillers with rated cooling capacity below 2,000 kW for industrial process applications. High temperature process chillers are capable of delivering leaving water temperatures of between 2°C and 12°C. For water leaving temperatures above 12°C there is no minimum efficiency requirement set by the regulation.

In addition regulation 2015/1095 affects any capacity Process Chillers operating at design capacity that can generate outlet fluid temperature of -8°C (Medium Temperature) or -25°C (Low Temperature - Out of scope of this guide). There is no limitation in terms of cooling capacity of the chiller so, unlike the High Temperature Process regulation, in this case it applies to chillers above 2,000 kW.

Calculation method

Rating report provided by the manufacturer must specify the calculation method regarding the water flow.SEPR is measuring the efficiency of a chiller applied to a process where normally the requested temperature is fixed among the year.Therefore in that case there are only two possible methods.

SEPR - Seasonal Energy Performance Ratio

Ecodesign regulation 2016/2281 and 2015/1095 introduces a new indicator called Seasonal Energy Performance Ratio (SEPR), which is the ratio of annual cooling demand to annual electrical energy consumption.

SEPR is calculated from an average climate reference with ambient temperature ranging from -19°C up to 38°C, and with corresponding operating hours at each temperature bin.

For Process cooling the operating load ranges from 100% down to 80%.

• Variable Flow reduces energy use at part load through reduced waterside pressure drop. Variable Speed Pumps must be fitted to the system to benefit from this savings.


• It is crucial to check the chilled water conditions used to determine the SEPR when comparing the seasonal energy efficiency of chillers.

Efficiency requirements set by REGULATION 2016/2281 High Temperature Process Chillers

Regulation 2016/2281 sets minimum efficiency levels for positive leaving water temperature chillers (high temperature chillers) rated up to 2,000 kW used in industrial process cooling applications.There is no SEPRHT requirement for chillers and heat pumps that apply to other regulations.

Efficiency requirements set by REGULATION 2015/1095 Medium Temperature Process Chillers

Regulation 2015/1095 sets minimum efficiency levels for chillers with negative leaving water temperature used in industrial process cooling applications. Medium temperature process chillers are defined as units capable of operating at -8°C leaving temperature.Chillers that applies to this regulation (SEPRMT) are excluded to the other Ecodesign regulations (like 2016/2281)

Design points for Process Chillers

The regulation requires to calculate the part load efficiencies at A, B, C, D rating points as per below table. For the rest of the temperatures covered by the regulation, the values are calculated using an interpolation and extrapolation process. Each point is weighted by the BIN hours defined by the standard. The calculation process is similar to the comfort one so you might refer to the calculation example for a better understanding (page 14).

Note: SEPRMT for chillers charged with refrigerant gas with GWP < 150 can lower the MEPS value by a maximum of 10%.


SCOP- Seasonal Coefficient of Performance

Ecodesign regulation 813/2013 introduces a new indicator called Seasonal Coefficient of Performance (SCOP), which is the ratio between the annual heating demand and the annual electrical input energy over the entire heating season.

SCOP is calculated using standard EN14825, which takes the following into account:• Seasonal efficiency while the compressor is running (SCOPon)• Electrical consumption when the compressor is not running: crankcase heater, standby or OFF mode• Backup heater required to achieve the defined heating design load

SCOP takes into account the energy efficiency achieved at each outdoor temperature of an average climate weighted by the number of BIN hours for each of those temperatures. The standard divides Europe in three climate zones, selecting a reference city for each of them and adopting its temperature profile. The “Average” temperature profile is mandatory and corresponds to Strasbourg. There is no cooling efficiency requirement (neither comfort nor process) for heat pumps affected by regulation 813/2103.

Published regulation 813/2013 affects all Heat Pumps (both air and water cooled) with a rated heating output below 400 kW (measured at -10°C ambient)

It relates to units used for space heating application that supply hot water and covers two sub-categories based on the leaving water temperature: low temperature and medium temperature.

Low temperature heat pump means a heat pump space heater that is specifically designed for low-temperature application, and that cannot deliver heating water with an outlet temperature of 52°C at an inlet dry (wet) bulb temperature of -7°C (-8°C) in the reference design conditions for average climate.

Low temperature application means an application where the heat pump space heater delivers its declared capacity for heating at an indoor heat exchanger outlet temperature of 35°C.

Medium temperature application means an application where the heat pump space heater or heat pump combination heater delivers its declared capacity for heating at an indoor heat exchanger outlet temperature of 55°C.

Calculation methodAn important point that must be specified on the manufacturers rating report is the calculation method regarding the water flow and outlet temperature. According regulation there are four possible methods.

• Variable Outlet decreases the leaving water temperature at partial load. This reduces the lift required by the heat pump, reducing energy use significantly. To provide this rating, chillers must be capable of automatic water temperature reset based on outdoor ambient temperature. With this capability, even projects without advanced building control systems can benefit.

• Variable Flow reduces energy use at part load through reduced waterside pressure drop. Variable Speed Pumps must be fitted to the system to benefit from this savings.


• It is crucial to check the water conditions used to determine the SCOP when comparing the seasonal energy efficiency of different heat pumps.

The number of operating hours for a heat pump covered by SCOP is 4910h (56% ot the total year hours).

Design points Heat Pumps (for “Average” Temperature Profile)

The regulation requires to calculate the part load efficiencies at A, B, C, D rating points as per below table. For the rest of the temperatures covered by the regulation, the values are calculated using an interpolation and extrapolation process. Each point is weighted by the BIN hours defined by the standard. The calculation process is similar to the comfort one so you might refer to the calculation example for a better understanding (page 14).

EXPLANATION: • Interpolate and extrapolate A, B, C, D values for the different ambient temperatures and weighten with the BIN hours defined by the Standards EN14825

• For units with staged compressor control, the part load efficiency at the different points is obtained directly by interpolation and extrapolation process (it’s the case of this example as unit is using inverter screw technology).

• For units with fixed speed compressor, a degradation factor must be applied to calculate the part load efficiencies along the different ambient temperatures.

EERbin = EERd x [CR / (Cdc x CR + (1 - Cdc))] where CR is Capacity Ratio and the degradation of coefficient Cdc is 0.9 when it’s not determined by a test.

EXPLANATION: • Consider all the electrical consumption when the compressor is not running: crankcase heater, standby or OFF mode• Convert in this way the SEERON in the SEER value (SEER < SEERON)• SEER is the ratio between the anual cooling demand (Qc) and the anual electrical input energy over the entire cooling season (Qce)

EXPLANATION: • Conversion of the SEER into ŋs,c• This value expresses SEER in terms of primary energy and it makes it possible to compare the energy efficiency of units using different energy sources

EXPLANATION: • Apply the MEPS defined by the regulation according to the type of unit and capacity

EXAMPLE • After applying the following formulas SEERON = 4.53 becomes SEER = 4.38 as the energy consumption when unit is OFF has taken into account

EXAMPLE • After applying the following formula SEER=4.38 becomes ŋs,c = 172.2%

In our example:

SEER = 4.38Air Cooled -> F(i) = 3%

EXAMPLE • It’s an Air Cooled unit with a cooling capacity of 664 kW so that means that the result ŋs,c = 172.2% passes Tier 1 but not Tier 2
