What is the significance of the CE marking and the declaration of incorporation for HVAC units? What you need to know.

February 16, 2018
The CE marking represents a confirmation from the manufacturer of a product, stating that – in accordance with EU Regulation 765/2008 – the product fulfils the fundamental requirements of the directives that apply to it. It is not a seal of quality.

Comfort ventilation: just a hype or absolute necessity?

January 18, 2018
Hardly any new residential building can do without controlled ventilation: As a rule, new buildings are so well insulated for energy reasons that there is no spontaneous exchange of air. However, comfort ventilation also makes sense for existing houses.

Calculating the supply air flow with the help of the load calculation – what you need to know.

May 29, 2017
The purpose of a hall ventilation system is to distribute supply air by means of a controlled and therefore calculable indoor air flow in order to dissipate heat loads and pollutant loads. There are various types of air guidance system which can perform this task. A design procedure is therefore required which makes it possible to assess the potential air guidance systems and select the best one for the requirements in question.

Pollution in the working area – what you need to know.

March 14, 2017
Pollution in the working area depends on the air flow concept as well as the type, arrangement and magnitude of the heat loads; beyond that, it depends on the type and arrangement of the air outlets. For example, pollution levels up to 100% with mixed ventilation can be reduced to below 10% using alternative air flow patterns.

Mixed and stratified ventilation in manufacturing halls – what you need to know.

January 11, 2017
The energy-efficient operation of hall ventilation is insured according to the current view by regulations in the Energy Saving Ordinance (EnEV) and the Energy-related Products Directive (ErP). They prescribe high requirements on the efficiency of room ventilation equipment. In fact, the actual energy saving starts much earlier, namely with the selection of the calculation method that is most suitable for the particular requirements on ventilation of a hall.

What is BIM? - advantages of BIM in the work of a HVAC planner

December 14, 2016
Access to information, priority setting and proper communication between industries are of key importance for the success of designing systems. We currently have files at our disposal, which can be used in 3D modeling of these buildings and building systems. This will enhance the design process and ensure a constant flow of information between all the participants of the process. And that is what BIM (Building Information Modeling) is all about.

Ventilation system for the production hall: naturally or mechanically?

November 9, 2016
Climate technology in a production hall has to be able to provide supply air and dissipate heat loads and/or pollutant loads. In principle, air flows can be transferred in two ways: either mechanically by ventilation and air-conditioning units or without machines by means of free (natural) ventilation using pressure differences. These pressure differences are created inside the hall by heat released during the production processes (negative pressure) and outside by wind pressure.
