BS EN 16905-4:2017EN 16905-4:2017 (E) 6 1 Scope 1.1 Scope of EN 16905 series This European Standard specifies the requirements, te
38、st 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
39、“GEHP appliance”. This European Standard only applies to appliances with a maximum heat input (based on net calorific value) not exceeding 70 kW at standard rating conditions. This European Standard only applies to appliances under categories I2H, I2E, I2Er, I2R, I2E(S)B, I2L, I2LL, I2ELL, I2E(R)B,

This European Standard only applies to appliances having: a) gas fired endothermic engines under the control of fully automatic control systems;b) closed sy
41、stem refrigerant circuits in which the refrigerant does not come into direct contact withthe fluid to be cooled or heated;c) where the temperature of the heat transfer fluid of the heating system (heating water circuit) doesnot exceed 105 C during normal operation;d) where the maximum operating pres
42、sure 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 appliances only when used for space heating or space cooling or for refrigeration, with or without heat recovery. The applia
43、nces 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.
44、 The above appliances can have one or more primary or secondary functions. This European Standard 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 (co
45、nsisting of several parts), this European Standard applies only to those designed and supplied as a complete package.
