European foreword

This document (prEN 12309-3:2022) 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 12309-3:2014, EN 12309-4:2014 and EN 12309-5:2014.

In comparison with the previous edition, the following technical modifications have been made:

— The content of previous standards EN 12309-3:2014, EN 12309-4:2014 and EN 12309-5:2014 has

been merged;

— Nomenclature has been updated to be aligned with Commission Regulation (EU) No 813/2013 of 2

August 2013, Commission Delegated Regulation (EU) No 811/2013 of 18 February 2013,

Commission Regulation (EU) No 2016/2281 of 30 November 2016;
— Test conditions have been rationalized;
— cpump definition and application has been better detailed;
— Test methods have been simplified;
— Permissible deviations have been revised;

— Informative Annex F (Measurement control criteria for water(brine) to water(brine) appliances)

has been deleted.

This document has been prepared under a Standardization Request given to CEN by the European

Commission and the European Free Trade Association, and supports essential requirements of EU

Directive(s) / Regulation(s).

For relationship with EU Directive(s) / Regulation(s), see informative Annex ZA, ZB or ZC, which is an

integral part of this document.

This standard comprises parts under the general title, Gas-fired sorption appliances for heating and/or

cooling with a net heat input not exceeding 70 kW. A list of all parts in a series can be found on the CEN

website.

1 Scope
1.1 Scope of EN 12309 series

Appliances covered by this document include one or a combination of the following:

— gas-fired sorption chiller;
— gas-fired sorption chiller/heater;
— gas-fired sorption heat pump;
— hybrids based on gas sorption appliances

This document applies to appliances designed to be used for space heating or cooling or refrigeration

with or without heat recovery.

This document applies to appliances having flue gas systems of type B and type C (according to

EN 1749:2020) and to appliances designed for outdoor installations. EN 12309 does not apply to air

conditioners, it 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 EN 12309-1:2014).

In the case of packaged units (consisting of several parts), this document applies only to those designed

and supplied as a complete package.

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. All the symbols given in this text are to be used regardless of the language used.

1.2 Scope of this Part 3 of EN 12309

This part of EN 12309 specifies the requirements, test methods and conditions 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 appliance. This data can be used in particular

to calculate the seasonal efficiency of the appliance.

4.2 Classification of gases

Gases are classified into three families, divided into groups according to the value of the Wobbe index.

Families and groups of gas used in this standard are in accordance with those of the EN 437:2021.

4.3 Classification of appliances

4.3.1 Classification according to the mode of air supply and evacuation of the combustion

products
The types of appliances as defined in EN 1749:2020 apply.
4.3.2 Classification according to denomination

Appliances are denominated in such a way that the heat transfer medium for the outdoor heat

exchanger is indicated first, followed by the heat transfer medium for the indoor heat exchanger.

Examples of such appliances are given in Table 1.
