Description

Thermostaten, Einrichtungen zur Konstanthaltung einer Temperatur in einem Raum, sind allgemein dadurch gekennzeichnet, daß ein temperaturempfindliches Glied (Thermometer oder Druckdose) eine Wärmequelle steuert, im einfachsten Falle periodisch ein- und ausschaltet. Thermostats, devices for maintaining a constant temperature in a room, are generally characterized by having a temperature sensitive Element (thermometer or pressure cell) controls a heat source, in the simplest case switches on and off periodically.

Wenn man voraussetzt, daß ein bestimmter konstanter Temperaturunterschied J t am temperaturempfindlichen Glied notwendig ist zum Einschalten und Ausschalten der Wärmezufuhr, so steigt die I>eriodendauer, mit der die Wärmezufuhr ein- und ausgeschaltet wird, mit der Wärmekapazität des geregelten Raumes an. If one assumes that a certain constant temperature difference J t on the temperature-sensitive element is necessary for switching on and off the supply of heat, the period increases with which the supply of heat is introduced and is switched off, with the heat capacity of the controlled room.

Dieser Periodendauer ist auch die Anheizzeit des Thermostaten, d. h. die Zeit, die nötig ist, den Thermostaten von der Raumtemperatur auf die Solltemperatur aufzuheizen, proportional. This period is also the heating-up time of the thermostat, i. H. the time it takes to move the thermostat from room temperature to the setpoint temperature heat up, proportional.

Im Im allgemeinen haben Thermostaten eine erhebliche Anheizzeit, die mit wachsenden Abmessungen ansteigt.In general, thermostats have a considerable heating-up time increases with increasing dimensions.

Erfindungsgemäß erreicht man besonders kleine Wärmekapazitäten und damit kleine Anheizzeiten, wenn man die Volumenänderung einer Flüssigkeit, die den temperaturgeregelten Raum umgibt, für die Steuerung der Wärmezufuhr verwendet. According to the invention, particularly small heat capacities are achieved and thus short heating-up times when one considers the change in volume of a liquid that has the temperature-controlled room surrounds, used for controlling the supply of heat.

Für kleine temperaturstabilisierte Räume, wie sie z. B. für Temperaturmessungen mit Thermoelementen für das ergleichselement benötigt werden, kann die Ausführung z. B. so erfolgen, daß der temperaturstahilisierte Raum 1 von dem Quecksilberreservoir 2 des Thermometers umschlossen ist. Die Wärmeverluste werden durch eine Heizwicklung 3 ersetzt, die das Quecksilberreservoir umgibt. Das Ganze ist mit der Wärmeisolierung 4 umgeben. Die Schaltkontakte des Thermometers sind mit 5 bezeichnet. For small, temperature-stabilized rooms, such as those used in B. for temperature measurements with thermocouples are required for the equalizing element, the z. B. be done so that the temperature-stabilized space 1 from the mercury reservoir 2 of the thermometer is enclosed. The heat losses are due to a heating coil 3 that surrounds the mercury reservoir. The whole thing is with the thermal insulation 4 surrounded. The switching contacts of the thermometer are marked 5.

PATENTANSPRUCIIE I. Thermostat mit kleiner Einstelidauer, dadurch gekennzeichnet, daß der Wärmefluß von der Heizung zum temperaturstabil isierten Raum lz'v. bei abgeschalteter Heizung vom stabilisierten Raum zur IGmgebung im wesentlichen über das temperaturempfindl iche Steuerglied erfolgt. PATENT CLAIM I. Thermostat with short setting time, thereby characterized in that the heat flow from the heater to the temperature-stabilized Room lz'v. with the heating switched off from the stabilized room to the environment essentially takes place via the temperature-sensitive control element.
