The picture shows a glass surface on which numerous raindrops are scattered. The drops form a random pattern and allow the light to shine through diffusely, creating a calm and cool atmosphere.The picture shows a glass surface on which numerous raindrops are scattered.

Dew Point Monitoring and Ventilation Control

Avoiding Condesation and Mould Formation by Temperature and Ventilation Control

The dew point temperature is that temperature at which condensation develops on a surface.

For example: At an air temperature of 24.0°C and at 60% relative humidity, the dew point is at a temperature of 15.8°C. If there is a surface in this room that is 15.8°C or colder, water droplets will develop on it.

The objective of dew point monitoring is to avoid this.

The image shows a diagram of a climate control system in a building. It emphasises the dangers of condensation on cold pipes and describes the functions of various components such as the room controller, temperature sensor and air conditioning actuator.

Background knowledge

How does condensation occur?

In buildings, condensation, sometimes also referred to as „dew water“, occurs particularly on cooled pipes and surfaces of air conditioning systems.

The moisture of the warm room air can settle here if surface and dew point temperatures approach similar values.

Measures

What can I do about condensation?

Thanks to the monitoring process, the building automation system can implement timely measures in order to avoid droplet formation.

For example, the temperature of the coolant may be raised (reduction of air conditioning), the room temperature may be raised, or the air humidity lowered (ventilation).

Elsner Elektronik devices support

Smart combination against condensation water

Manual monitoring is very time-consuming and uncomfortable. Therefore, many devices from Elsner Elektronik offer integrated dew point monitoring.

Through the smart combination of Elsner Elektronik sensors, room controllers and actuators, the danger is recognised in good time and countermeasures can be taken.

Connected windows, fans, heating and air conditioning systems are controlled to prevent the formation of condensation water.

Garanzia legale

Avviso armonizzato UE sulla garanzia legale

Garanzia legale minima di due anni per i beni venduti nell'Unione europea.

I consumatori possono far valere i loro diritti nell'ambito della garanzia legale di conformità, ad esempio se i beni:

  • non corrispondono alla descrizione;
  • non funzionano come previsto.

I venditori sono responsabili di qualsiasi difetto di conformità esistente al momento della consegna dei beni e che si manifesta entro il periodo della garanzia legale. In tal caso i venditori sono tenuti a offrire:

  • la riparazione o sostituzione gratuita;
  • in alcuni casi, una riduzione del prezzo o il rimborso integrale.

Alcuni paesi prevedono un periodo di garanzia legale più lungo. Per i beni di seconda mano può valere un periodo più breve, ma non inferiore a un anno.

Cosa fare se si ricevono beni non conformi:

  1. contattare quanto prima il venditore per segnalare il problema;
  2. fornire la prova dell'acquisto, ad esempio una ricevuta, una fattura o un estratto conto bancario.

I venditori e i produttori possono anche offrire garanzie commerciali, che si applicano indipendentemente dalla garanzia legale. Ad esempio, questa etichetta GARAN rappresenta una garanzia commerciale di durabilità offerta dal produttore senza costi aggiuntivi, che copre il bene nel suo complesso.
