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 standard only applies to appliances with a maximum heat input (based on net calorific value) not exceeding 70 kW at standard rating conditions. This standard only applies to appliances under categories I2H, I2E, I2Er, I2R, I2E(S)B, I2L, I2LL, I2ELL, I2E(R)B, I2ESi, I2E(R), I3P, I3B, I3B/P, II2H3+, II2Er3+, II2H3B/P, II2L3B/P, II2E3B/P, II2ELL3B/P, II2L3P, II2H3P, II2E3P and II2Er3P according to EN 437. This standard only applies to appliances having: - gas fired endothermic engines under the control of fully automatic control systems; - closed system refrigerant circuits in which the refrigerant does not come into direct contact with the fluid to be cooled or heated; - where the temperature of the heat transfer fluid of the heating system (heating water circuit) does not exceed 105 during normal operation; - where the maximum operating pressure in the - heating water circuit (if installed) does not exceed 6 bar - domestic hot water circuit (if installed) does not exceed 10 bar. This standard applies to appliances only when used for space heating or space cooling or for refrigeration, with or without heat recovery. The appliances having their condenser cooled by air and by the evaporation of external additional water are not covered by this standard. Packaged units, single split and multisplit systems are covered by this standard. Single duct and double duct units are covered by this standard. The above appliances can have one or more primary or secondary functions. This standard is applicable to appliances that are intended to be type tested. Requirements for appliances that are not type tested wo
