Abstract

The device has a sensor that measures the temperature of a refrigerant fluid at an output of an exchanger. The sensor transmits the measured temperature to a system, which compares the sensed temperature to a selected reference temperature. The system alters the speed of the fluid at the output so that the temperature remains close to the reference temperature, irrespective of power being delivered by the exchanger.

Description

2857440 -1-2857440 -1-

La présente invention concerne un dispositif qui permet de réguler la température d'un fluide caloriporteur ou réfrigérant en sortie d'un échangeur d'un générateur par rapport à une température de référence choisie en faisant varier la vitesse de ce fluide au contact de l'échangeur et ce quelque soit la puissance délivrée par l'échangeur.  The present invention relates to a device which makes it possible to regulate the temperature of a heat transfer fluid or refrigerant at the outlet of a heat exchanger of a generator with respect to a reference temperature chosen by varying the speed of this fluid in contact with the exchanger and whatever the power delivered by the exchanger.

Les générateurs thermiques ou frigorifiques fournissent une quantité de calories ou de frigories variable en fonction de leur gamme de puissance et la température du fluide en sortie de leurs échangeurs ( généralement de l'air) va varier en fonction cette puissance, ce qui crée par rapport aux températures que l'on souhaite obtenir dans les volumes à tempérer, des écarts importants de température et de ce fait, accumule dans les points hauts ou bas de ces volumes un excès de calories ou de frigories d'ou une consommation inutile en énergie.  Thermal or refrigeration generators provide a variable amount of calories or frigories depending on their power range and the fluid temperature at the outlet of their exchangers (usually air) will vary depending on this power, which creates relative at the temperatures that it is desired to obtain in the volumes to be tempered, large differences in temperature and, as a result, accumulate in the high or low points of these volumes an excess of calories or frigories or unnecessary energy consumption.

Ce système a l'avantage de pouvoir contrôler la température en sortie d'un échangeur et de l'adapter par rapport aux températures que l'on souhaite obtenir dans les volumes à tempérer évitant ainsi les accumulations de températures trop élevées dans les points hauts et les accumulations de températures trop basses dans les points bas de ces volumes. On pourra à partir de conduits de souffler l'air chaud dans les parties les plus basses des volumes à chauffer et l'air froid dans les parties les plus hautes des volumes à refroidir et en augmentant ainsi le brassage de l'air obtenir une meilleure homogénéisation des températures dans ces volumes et une économie d'énergie conséquente.  This system has the advantage of being able to control the temperature at the outlet of an exchanger and to adapt it to the temperatures that it is desired to obtain in the volumes to be tempered, thus avoiding the accumulation of temperatures that are too high in the high points and the accumulations of temperatures too low in the low points of these volumes. It will be possible from ducts to blow hot air in the lower parts of the volumes to be heated and the cold air in the highest parts of the volumes to be cooled and thus increasing the mixing of the air to obtain a better homogenization of the temperatures in these volumes and a consequent saving of energy.

Les applications sont nombreuses tant sur le plan domestique qu' industriel.  The applications are numerous both at the domestic and industrial levels.

Un capteur mesure la température du fluide en sortie de l'échangeur, la transmet à un système qui la compare à une température de référence choisie. Ce système va agir sur la vitesse du fluide au contact de l'échangeur pour que la température en sortie de l'échangeur reste voisine de la référence choisie et ce quelque soit la puissance fournie par l'échangeur, sauf s'il n'a pas ou n'a plus la capacité suffisante pour fournir l'échange attendu, notamment lors des phases de démarrage ou de mise en arrêt.  A sensor measures the temperature of the fluid at the outlet of the exchanger, transmits it to a system that compares it to a chosen reference temperature. This system will act on the speed of the fluid in contact with the exchanger so that the temperature at the outlet of the exchanger remains close to the chosen reference and whatever the power supplied by the exchanger, unless it has not or no longer has sufficient capacity to provide the expected exchange, especially during the start-up or shutdown phases.

2857440 -2- Selon certaines configurations des appareils, le système assurera un débit du fluide minimum dés leurs mises en fonctionnement pour permettre au capteur de mesurer la température du fluide en sortie de l'échangeur.  According to certain device configurations, the system will ensure a minimum fluid flow from their start-up to allow the sensor to measure the temperature of the fluid at the outlet of the exchanger.

Dans tous les cas, il est souhaitable de canaliser le passage du fluide au contact de l'échangeur.  In all cases, it is desirable to channel the passage of the fluid in contact with the exchanger.
