EMC at air/water heat pumps: Do not disturb! The European EMC Directive (2014/30/EU) defines electromagnetic compatibility as “the ability of equipment to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances. ” It applies to all electricity-consuming apparatus, including air/water heat pumps, which are today increasingly popular as an environmentally friendly heating solution. This means that both the components used in the heat pumps – such as fans – and the apparatus as a whole may only generate a certain level of electromagnetic disturbance and may itself only be influenced by a certain level of such disturbance. The levels are defined in standards, compliance with which must be ensured by heat pump manufacturers. Well-equipped EMC test laboratories combined with engineering expertise are a prerequisite for this.»
Safety first, not just for air/water heat pumps Today’s heating systems require concepts based on renewable energies. Heat pumps are therefore becoming ever more popular in both new buildings and renovations and are subsidized by funding in many cases.

They use thermal energy from the ambient air and transfer it to the hot water circuit via an intermediate circuit with refrigerant.»

Soundcheck for heatpumps: Psychoacoustics for minimum noise generation Air/water heatpumps with heat outputs from 3 to 30 kW enjoy a high level of acceptance in heating technology. However, they do not work completely silently and the more dense the buildings are, the more the neighbors can get disturbed by noise pollution. It is by no means just the measurable sound pressure level that is crucial, but human noise perception, which is where psychoacoustics and its examination methods come into play.»
