1.1 Scope of EN 16905 This European Standard specifies the requirements, test methods and test conditions for the rating and performance calculation of air conditioners and heat pumps using either air, water or brine as heat transfer media, with gas-fired endothermic engine driven compressors when used for space heating, cooling and refrigeration, hereafter referred to as "GEHP appliance". This European Standard only applies to GEHP appliances with a maximum heat input (based on net calorific value) not exceeding 70 kW at standard rating conditions. This standard only applies to GEHP appliances under categories Iˇ2H^, Iˇ2E^, Iˇ2Er^, Iˇ2R^, Iˇ2E(S)B^, Iˇ2L^, Iˇ2LL^, Iˇ2ELL^, Iˇ2E(R)B^, Iˇ2ESi^, Iˇ2E( R )^, Iˇ3P^, Iˇ3B^, Iˇ3B/P^, IIˇ2H3^+, IIˇ2Er3^+, IIˇ2H3B/P^, IIˇ2L3B/P^, IIˇ2E3B/P^, IIˇ2ELL3B/P^, IIˇ2L3P^, IIˇ2H3P^, IIˇ2E3P^ and IIˇ2Er3P^ according to EN 437:2018. This standard only applies to GEHP appliances having: a) gas fired endothermic engines under the control of fully automatic control systems; b) closed system refrigerant circuits in which the refrigerant does not come into direct contact with the fluid to be cooled or heated; c) where the temperature of the heat transfer fluid of the heating system (heating water circuit) does not exceed 105 oC during normal operation; d) where the maximum operating pressure in the 1) heating water circuit (if installed) does not exceed 6 bar 2) domestic hot water circuit (if installed) does not exceed 10 bar. This European Standard applies to GEHP appliances only when used for space heating or space cooling or for refrigeration, with or without heat recovery. The GEHP appliances having their condenser cooled by air and by the evaporation of external additional water are not covered by this European Standard. Packaged units, single split and multisplit systems are covered by this European Standard. Single duct and double duct units are covered by this European Standard. The above GEHP appliances can have one or more primary or secondary functions. This European Standard is applicable to GEHP appliances that are intended to be type tested. Requirements for GEHP appliances that are not type tested would need to be subject to further consideration. In the case of packaged units (consisting of several parts), the standard applies only to those designed and supplied as a complete package. NOTE All the symbols given in this text are used regardless of the language used. 1.2 Scope of EN 16905-2 This part of EN 16905 specifies the safety requirements, the safety test conditions and the safety test methods of gas-fired endothermic engine driven heat pumps for heating and/or cooling mode including the engine heat recovery.
