Gas-fired sorption appliances for heating and/or cooling with a net heat input not exceeding 70 kW - Part 4: Test methods
Scope of EN 12309 series
Appliances covered by EN 12309 include one or a combination of the following:
- gas-fired sorption chiller;
- gas-fired sorption chiller/heater;
- gas-fired sorption heat pump;
EN 12309 applies to appliances only when used for space heating or cooling or refrigeration with or without heat recovery. Appliances can be monovalent, bivalent or hybrid types.
EN 12309 applies to appliances having flue gas systems of type B and C (according to CEN/TR 1749) and to appliances designed for outdoor installations. EN 12309 applies to appliances that can be single ducted or double ducted.
EN 12309 only applies to appliances having
- integral burners under the control of fully automatic burner control systems,
- closed system refrigerant circuits in which the refrigerant does not come into direct contact with the water or air to be cooled or heated,
- mechanical means to assist transportation of the combustion air and/or the flue gas.
The above appliances can have one or more primary or secondary functions (i.e. heat recovery - see definitions in prEN 12309 1:2012) and EN 12309 applies to all such functions providing that the function concerned is dependent on circulation of fluid (refrigerant and/or solution) within the absorption, adsorption or refrigerant circuit(s).
NOTE 1 Any appliance function that is not dependent on circulation of the fluid within the absorption, adsorption, or refrigerant circuit(s) should be assessed separately.
EN 12309 is applicable to appliances that are intended to be type tested. Requirements for appliances that are not type tested would need to be subject to further consideration.
In the case of packaged units (consisting of several parts), EN 12309 applies only to those designed and supplied as a complete package.
EN 12309 does not apply to air conditioners.
The appliances having their condenser cooled by air and by the evaporation of external additional water are not covered by EN 12309.
Installations used for heating and/or cooling of industrial processes are not within the scope of EN 12309.
NOTE 2 All the symbols given in this text should be used regardless of the language used.
Scope of this Part 4 to EN 12309
This part of EN 12309 specifies the test methods for gas-fired sorption appliances for heating and/or cooling with a net heat input not exceeding 70 kW.
This part of EN 12309 deals particularly with test protocols and tools to calculate the capacity, the gas utilization efficiency and the electrical power input of the tested appliance. These data can be used in particular to calculate the seasonal efficiency of the appliance.

Foreword
This document (prEN 12309-4:2012) has been prepared by Technical Committee CEN/TC 299 “Gas-fired
sorption appliances, indirect fired sorption appliances, gas-fired endothermic engine heat pumps and domestic
gas-fired washing and drying appliances”, the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 12309-2:2000.
EN 12309 comprises the following parts under the general title «Gas-fired sorption appliances for heating
and/or cooling with a net heat input not exceeding 70 kW»:
Part 1: Terms and definitions;
Part 2: Safety;
Part 3: Test conditions;
Part 4: Test methods;
Part 5: Requirements;
Part 6: Calculation of seasonal performances;
Part 7: Specific provisions for hybrid appliances;
Part 8: Environmental aspects.
Parts 1 and 2 to EN 12309 will supersede EN 12309-1:1999, whereas Part 1 and Parts 3 to 7 of EN 12309 will
supersede EN 12309-2:2000. Parts 1 to 7 have been prepared to address the essential requirements of the
European Directive 2009/142/EC relating to appliances burning gaseous fuels (see informative Annex ZA of
EN 12309-2:20xx for safety aspects and Annex ZA of prEN 12309-5:2012 for rational use of energy aspects).
These documents are linked to the following European Directives:
Energy Related Products Directive (2009/125/EC) in terms of tests conditions, tests methods and
seasonal performances calculation methods under Mandate M/495 (see Annex ZB of
prEN 12309-5:2012);
Promotion of the Use of Renewable Energy Directive (2009/28/EC – Annex VII) (see Annex A of
prEN 12309-5:2012).
For the relationship with EU Directive(s), see informative Annexes ZA and ZB in EN 12309-2:20xx and in
prEN 12309-5:2012, which are an integral part of this document. These documents will be reviewed whenever
new mandates could apply.

1 Scope
1.1 Scope of EN 12309 series
Appliances covered by EN 12309 include one or a combination of the following:
gas-fired sorption chiller;
gas-fired sorption chiller/heater;
gas-fired sorption heat pump.
EN 12309 applies to appliances only when used for space heating or cooling or refrigeration with or without
heat recovery. Appliances can be monovalent, bivalent or hybrid types.
EN 12309 applies to appliances having flue gas systems of type B and C (according to CEN/TR 1749) and to
appliances designed for outdoor installations. EN 12309 applies to appliances that can be single ducted or
double ducted.
EN 12309 only applies to appliances having
integral burners under the control of fully automatic burner control systems,
closed system refrigerant circuits in which the refrigerant does not come into direct contact with the water
or air to be cooled or heated,
mechanical means to assist transportation of the combustion air and/or the flue gas.
The above appliances can have one or more primary or secondary functions (i.e. heat recovery - see
definitions in prEN 12309-1:2012) and EN 12309 applies to all such functions providing that the function
concerned is dependent on circulation of fluid (refrigerant and/or solution) within the absorption, adsorption or
refrigerant circuit(s).
NOTE 1 Any appliance function that is not dependent on circulation of the fluid within the absorption, adsorption, or
refrigerant circuit(s) should be assessed separately.
EN 12309 is applicable to appliances that are intended to be type tested. Requirements for appliances that
are not type tested would need to be subject to further consideration.
In the case of packaged units (consisting of several parts), EN 12309 applies only to those designed and
supplied as a complete package.
EN 12309 does not apply to air conditioners.
The appliances having their condenser cooled by air and by the evaporation of external additional water are
not covered by EN 12309.
Installations used for heating and/or cooling of industrial processes are not within the scope of EN 12309.
NOTE 2 All the symbols given in this text should be used regardless of the language used.
1.2 Scope of this Part 4 to EN 12309
This part of EN 12309 specifies the test methods for gas-fired sorption appliances for heating and/or cooling
with a net heat input not exceeding 70 kW.
This part of EN 12309 deals particularly with test protocols and tools to calculate the capacity, the gas
utilization efficiency and the electrical power input of the tested appliance. These data can be used in
particular to calculate the seasonal efficiency of the appliance.

determined in accordance with the direct method at the water or brine (indoor) heat exchanger(s), by
determination of the volume or mass flow rate of the heat transfer medium, and the inlet and outlet
temperatures, taking into consideration the specific heat capacity and density, or the enthalpy change, of the
heat transfer medium (see 4.2.1.2, 4.2.1.3, 4.2.1.4, 4.2.1.5).
4.2.1.2 Measured heating capacity
