| Resumen: | This series specifies the requirements, test methods and test conditions for the rating and performance calculation of gas-fired endothermic engine driven heat pumps for heating and/or cooling mode including the engine heat recovery, to be used outdoor. This series only applies to appliances with a maximum heat input (based on net calorific value) not exceeding 70 kW at standard rating conditions. This series 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 437:2021. This series only applies to 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 °C 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 series applies to appliances only when used for space heating or space cooling or for refrigeration, with or without heat recovery. This series 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. |
