Components for BAC control loop - Sensors - Part 1: Room temperature sensors
This document specifies requirements and test methods for room temperature sensors used to control the room temperature.
This document is applicable to wall mounted and flush mounted room temperature sensors.
The following aspects are not covered by this document:
- pendulum temperature sensors;
- ceiling mounted temperature sensor;
- extract air temperature sensors.
NOTE The measured value available at the output of the sensor is influenced by the place where the sensor device is located and factors such as air velocity, wall temperature, self/waste heating of the device and the air temperature. The perceived temperature, which is important for the well-being of a person, depends among other factors on air temperature, temperature of the surrounding walls and air flow rate as indicated in EN ISO 7730.
The temperature sensor element can be combined with other sensors in one device. This document only deals with the room temperature sensing of this devices. Other sensors are not covered except of their influence on the room temperature sensing (e.g. self-heating).
This document specifies sensor characteristics contributing to the determination of the control accuracy of individual zone controller according to EN 15500 1.
Komponenten für den BAC-Regelkreis - Sensoren - Teil 1: Raumtemperaturfühler
Dieses Dokument legt Anforderungen und Prüfverfahren für zur Regelung der Raumtemperatur verwendete Raumtemperatursensoren fest.
Dieses Dokument gilt für wandmontierte und bündig montierte Raumtemperatursensoren.
Die folgenden Aspekte werden in diesem Dokument nicht behandelt:
- Pendeltemperatursensoren;
- deckenmontierter Temperatursensor;
- Ablufttemperatursensoren.
ANMERKUNG Der am Ausgang des Sensors verfügbare gemessene Wert wird durch die Position des Sensors und Faktoren wie Luftgeschwindigkeit, Wandtemperatur, Eigenerwärmung/Abwärme des Geräts und die Lufttemperatur beeinflusst. Die wahrgenommene Temperatur, die für das Wohlbefinden einer Person wichtig ist, hängt von anderen Faktoren wie der Lufttemperatur, der Temperatur der umgebenden Wände und dem Luftstrom nach EN ISO 7730 ab.
Das Temperatursensor-Element kann mit anderen Sensoren in einem Gerät kontrolliert werden. Dieses Dokument behandelt nur die Raumtemperaturmessung dieses Geräts. Andere Sensoren werden lediglich hinsichtlich ihres Einflusses auf die Temperaturmessung (z. B. Eigenerwärmung) behandelt.
Dieses Dokument legt Sensoreigenschaften fest, die zu der Bestimmung der Regelgenauigkeit einzelner Zonenregler nach EN 15500 1 beitragen.
Composants d'une boucle de régulation - Capteurs - Partie 1 : Capteurs de température
Le présent document spécifie les exigences et les méthodes d'essai pour les capteurs de température ambiante utilisés pour réguler la température ambiante.
Le présent document couvre les capteurs de température ambiante à montage mural et encastrés.
Les aspects suivants ne sont pas couverts par le présent document :
- capteurs de température pendulaires ;
- capteurs de température montés au plafond ;
- capteurs de température d'air extrait.
NOTE La valeur mesurée disponible à la sortie du capteur est influencée par l'endroit où se trouve le dispositif de détection et par des facteurs tels que la vitesse de l'air, la température des parois, l'auto-échauffement ou l'échauffement résiduel du dispositif et la température de l'air. La température perçue, qui est importante pour le bien-être d'une personne, dépend entre autres facteurs de la température de l'air, de la température des parois environnantes et du débit d'air, comme indiqué dans l'EN ISO 7730.
L'élément capteur de température peut être combiné avec d'autres capteurs dans un même dispositif. Le présent document ne traite que de la détection de la température ambiante de ces dispositifs. Les autres capteurs ne sont pas couverts, à l'exception de leur influence sur la détection de la température ambiante (par exemple, l'auto-échauffement).
Le présent document spécifie les caractéristiques des capteurs contribuant à la détermination de la précision de régulation du régulateur de zone individuel selon l'EN 15500 1.
Sestavni deli za krmilno zanko BAC - Senzorji - 1. del: Senzorji za sobno temperaturo
Ta dokument določa zahteve in preskusne metode za senzorje za sobno temperaturo, ki se uporabljajo za regulacijo temperature v prostoru.
Ta dokument obravnava senzorje za sobno temperaturo, ki so nameščeni na steno in vgreznjeno.
Ta dokument ne zajema:
– nihajnih senzorjev temperature;
– senzorjev temperature, nameščenih na strop;
– senzorjev temperature pri odvajanju zraka.
OPOMBA: Na izmerjeno vrednost, ki je na voljo na izhodu senzorja, vplivajo lokacija senzorja in dejavniki, kot so hitrost zraka, temperatura stene, samo/odpadno ogrevanje naprave in temperatura zraka. Zaznana temperatura, ki je pomembna za dobro počutje osebe, je med drugim odvisna od temperature zraka, temperature okoliških sten in pretoka zraka, kot je navedeno v standardu EN ISO 7730.
Element senzorja temperature je mogoče kombinirati z drugimi senzorji v eni napravi. Ta dokument obravnava samo zaznavanje sobne temperature teh naprav. Drugi senzorji niso zajeti, razen njihov vpliv na zaznavanje sobne temperature (npr. samoogrevanje).
Ta dokument določa značilnosti senzorja, ki prispevajo k določanju natančnosti naprave za regulacijo posameznih con v skladu s standardom EN 15500-1.
