VBW Engineering air-handling units meet Ecodesign requirements
VBW Engineering offers a wide range of products that fully meet the requirements for the reduction of energy consumption and greater energy efficiency of the manufactured air-handling units effective from 1 January 2016. The Commission Regulation (EU) No. 1253/2014 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for ventilation units (Official Journal of the European Union L 337/8), introduced in July 2014, clarifies the requirements for the equipment manufacturers throughout the European Union.
We are pleased to announce that our products fully meet the requirements and, adapted to the latest regulations, further reduce the operating costs of the facilities, thereby improving their ecological value. Reduced energy consumption is very important for consumers considering purchasing the equipment of manufacturers who still did not adjust their production profile.
Specific ecodesign requirements apply to residential ventilation units (RVUs) and non-residential ventilation units (NRVUs). The table below shows the requirements applicable to NRVUs.Our products which meet the current requirements are even more user- and environment-friendly.
HRS – ‘heat recovery system’ means the part of a bidirectional ventilation unit equipped with a heat exchanger designed to transfer the heat contained in the (contaminated) exhaust air to the (fresh) supply air;
UVU – ‘unidirectional ventilation unit’ means a ventilation unit producing an air flow in one direction only, either from indoors to outdoors (exhaust) or from outdoors to indoors (supply), where the mechanically produced air flow is balanced by natural air supply or exhaust;
BVU – ‘bidirectional ventilation unit’ (BVU) means a ventilation unit which produces an air flow between indoors and outdoors and is equipped with both exhaust and supply fans;
VU – ‘ventilation unit’ means an electricity driven appliance equipped with at least one impeller, one motor and a casing and intended to replace utilised air by outdoor air in a building or a part of a building;;
NRVU – non-residential ventilation unit’ means a ventilation unit where the maximum flow rate of the ventilation unit exceeds 250 m3/h, and, where the maximum flow rate is between 250 and 1 000 m3/h, the manufacturer has not declared its intended use as being exclusively for a residential ventilation application;
RVU – residential ventilation unit’ means a ventilation unit where:
(a) the maximum flow rate does not exceed 250 m3/h;
(b) the maximum flow rate is between 250 and 1 000 m3/h, and the manufacturer declares its intended use as being exclusively for a residential ventilation application;
SFPint - ‘internal specific fan power of ventilation components (SFPint)’ (expressed in W/(m3/s)) is the ratio between the internal pressure drop of ventilation components and the fan efficiency, determined for the reference configuration;
