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.

Garantía legal

Aviso armonizado de la UE sobre la garantía legal

Garantía legal mínima de dos años para los bienes vendidos en la Unión Europea.

Los consumidores pueden hacer valer los derechos que les otorga la garantía legal de conformidad, por ejemplo, si los bienes:

  • no coinciden con la descripción;
  • no funcionan según lo previsto.

Los vendedores son responsables de cualquier falta de conformidad que existiera en el momento de la entrega de los bienes y que se ponga de manifiesto dentro del período de garantía legal. Los vendedores que se encuentren en tal situación están obligados a ofrecer:

  • la reparación o sustitución gratuitas;
  • en algunos casos, una reducción del precio o un reembolso total.

Algunos países tienen un período de garantía legal más largo. En el caso de los bienes de segunda mano, dicho período puede ser más corto, pero nunca inferior a un año.

Qué hacer si recibe bienes no conformes:

  1. Póngase en contacto con el vendedor lo antes posible para notificar el problema;
  2. Aporte pruebas de la compra, como un recibo, una factura o un extracto bancario.

Los vendedores y los productores también pueden ofrecer garantías comerciales, que se aplican independientemente de la garantía legal. Por ejemplo, la etiqueta GARAN representa una garantía comercial de durabilidad ofrecida por el productor sin coste adicional y que cubre la totalidad del bien.

Para obtener más información sobre sus derechos en un país específico, consulte la página que figura a continuación o pregunte al vendedor. https://europa.eu/youreurope/garantías
