This Standard specifies the laboratory test methods and test requirements for aerodynamic, energy rating and acoustic performance, of combined balanced units intended for use in a single dwelling. In the case of units consisting of several parts, this standard applies only to those designed and supplied as a complete package with the mount instructions. It covers unit that contain at least, within one or more casing: supply and exhaust air fans; air filters common control system. And one ore more of the additional components Air to water heat pump; Air to air heat pump air-to-air heat exchanger except units including either an air to air heat exchanger and/or air to air heat pump which are already covered from EN 13141-7. Detailed description covered by this standard is given in Chapter 5.The standard does not cover the thermal aspects of humidity transfer in the air-to-air heat exchanger. This standard does not deal with non-ducted units. This standard does not deal with collective units (centralised or semi-centralised systems) These combined balanced units can be connected to ground heat exchanger for air preheating, solar collector or other heating systems. This standard does not cover the testing of this. This standard does not cover units including combustion engine driven compression heat pumps and sorption heat pump.
