Abstract
Description
La présente invention conceme un dispositif pour améliorer les performances et le confort d'une installation de chauffage par pompe à chaleur. The present invention relates to a device for improving the performance and comfort of a heat pump heating installation.
On connaît déjà des installations de pompe à chaleur destinées au chauffage des habitations dans lesquelles la chaleur est puisée dans le sol extérieur au moyen d'un évaporateur enterré puis restituée à l'intérieur de la maison par un condenseur noyé dans le béton du local à chauffer. Heat pump installations are already known for heating dwellings in which the heat is drawn from the exterior soil by means of a buried evaporator and then returned to the interior of the house by a condenser embedded in the concrete of the room in heat.
Dans les pompes à chaleur à capteur enterré et à condenseur noyé dans la dalle, le fluide frigorigène sort du compresseur ci une température généralement comprise entre 70 et 110 C. Les réglementations actuelles limitent à 50 C la température d'un fluide en circulation dans un plancher chauffant. In heat pumps with buried sensor and condenser embedded in the slab, the refrigerant leaves the compressor at a temperature generally between 70 and 110 C. Current regulations limit the temperature of a fluid circulating in a heating floor.
II est donc impératif de réduire cette température afin de ne pas dépasser la température autorisée. It is therefore imperative to reduce this temperature so as not to exceed the authorized temperature.
Dans les installations actuelles, la baisse de température est réalisée par échange de chaleur entre le refoulement du compresseur et la partie froide du circuit frigorifique. Cette disposition réduit fortement les performances du système en limitant le
Coefficient de Performance à des valeurs de 3 à 3.5 alors qu'il pourrait dépasser 4 avec le dispositif objet de la présente invention.In current installations, the temperature drop is achieved by heat exchange between the compressor discharge and the cold part of the refrigeration circuit. This arrangement greatly reduces the performance of the system by limiting the
Coefficient of Performance at values from 3 to 3.5 when it could exceed 4 with the device which is the subject of the present invention.
Le dispositif selon l'invention permet de remédier à cet inconvénient. The device according to the invention overcomes this drawback.
Le dispositif selon l'invention est constitué d'un moyen d'échange avec l'air intérieur de la maison, ce moyen d'échange devant tre placé après la sortie des gaz chauds du compresseur et avant la pénétration des tubes dans le plancher chauffant. The device according to the invention consists of a means of exchange with the air inside the house, this means of exchange having to be placed after the exit of the hot gases from the compressor and before the penetration of the tubes into the heating floor. .
Selon une variante, le moyen d'échange peut tre placé dans une prise d'air extérieur, avant qu'il ne pénètre dans la maison et serve au chauffage de cet air extérieur. According to a variant, the exchange means can be placed in an outside air intake, before it enters the house and is used for heating this outside air.
La figure 1 représente schématiquement l'installation selon l'invention. FIG. 1 schematically represents the installation according to the invention.
La figure 2 représente une variante de ce dispositif. Figure 2 shows a variant of this device.
La figure 3 représente le moyen d'échange placé sur l'air extérieur. Figure 3 shows the exchange means placed on the outside air.
La figure 4 représente le moyen d'échange placé sur l'air intérieur. Figure 4 shows the exchange means placed on the indoor air.
La figure 5 représente une variante de ce dispositif. FIG. 5 represents a variant of this device.
La figure 6 représente le moyen d'échange constituant un radiateur. Figure 6 shows the exchange means constituting a radiator.
La figure 7 représente une variante de ce radiateur. Figure 7 shows a variant of this radiator.
Une installation de chauffage par pompe à chaleur selon l'invention figure 1, comprend un compresseur de fluide frigorigène 11 refoulant le gaz comprimé dans le condenseur 12 constitué d'un ensemble de tuyauteries noyées dans la dalle du local ci chauffer. Le fluide frigorigène condensé passe par le détendeur 13 puis dans l'évaporateur 14 avant de retourner dans le compresseur 11 pour un nouveau cycle. Un échangeur de chaleur 15 est inséré entre le compresseur 11 et le condenseur 12 afin d'échanger de l'énergie dans le but de réduire la température du fluide frigorigéne à t'entrée du condenseur 12. A heat pump heating installation according to the invention in FIG. 1, includes a refrigerant compressor 11 delivering the compressed gas into the condenser 12 consisting of a set of pipes embedded in the floor of the room to be heated. The condensed refrigerant passes through the pressure reducer 13 and then through the evaporator 14 before returning to the compressor 11 for a new cycle. A heat exchanger 15 is inserted between the compressor 11 and the condenser 12 in order to exchange energy in order to reduce the temperature of the refrigerant at the inlet of the condenser 12.
La figure 2 représente une variante ou l'échangeur 24 est ventilé par un ventilateur 23 assurant un échange de chaleur plus important. Le moyen d'échange 24 est inséré entre le compresseur 21 et le condenseur 22. Figure 2 shows a variant or the exchanger 24 is ventilated by a fan 23 ensuring a greater heat exchange. The exchange means 24 is inserted between the compressor 21 and the condenser 22.
La figure 3 représente le moyen d'échange 31 monté dans un caisson 32 équipé d'un ventilateur 33, aspirant t'air par la prise d'air extérieur 34 et soufflant I'air réchauffé dans la maison par la bouche 35. Le moyen d'échange 31 est inséré entre le compresseur 36 qui aspire le fluide frigorigène en provenance du capteur enterré 37, et le condenseur 38 noyé dans la dalle. FIG. 3 represents the exchange means 31 mounted in a box 32 fitted with a fan 33, sucking in air through the outside air intake 34 and blowing the air heated in the house through the mouth 35. The means exchange 31 is inserted between the compressor 36 which sucks in the refrigerant coming from the buried sensor 37, and the condenser 38 embedded in the slab.
La figure 4 représente le moyen d'échange 41 monté dans un caisson 42, éventuettement équipé d'une grille 43, I'ensemble formant convecteur et pouvant tre installé dans une partie visible de la maison. FIG. 4 represents the exchange means 41 mounted in a box 42, optionally equipped with a grid 43, the assembly forming a convector and being able to be installed in a visible part of the house.
La figure 5 représente une variante ou le caisson 51 comprend le moyen d'échange 52 ainsi que le distributeur de fluide frigorigène 53 assurant la répartition vers les différentes boucles du plancher par les brins 54. FIG. 5 represents a variant where the box 51 comprises the exchange means 52 as well as the refrigerant distributor 53 ensuring distribution to the different loops of the floor by the strands 54.
La figure 6 représente le moyen d'échange constituant un radiateur, et réalisé à titre d'exemple, avec des tubes métalliques 61 et des traverses 62 soudées de manière étanche. Le fluide frigorigène entre dans le radiateur par le tube 63 et ressort par le tube 64. FIG. 6 represents the exchange means constituting a radiator, and produced by way of example, with metal tubes 61 and crosspieces 62 welded in a leaktight manner. The refrigerant enters the radiator through the tube 63 and exits through the tube 64.
La figure 7 représente un radiateur 71 constitué d'éléments 72, vissés ou soudés, en fonte, en acier, en aluminium ou en toute autre matière et dans lesquels est inséré le tube échangeur 75 relié au compresseur par le tube 73 et relié au condenseur par le tube 74. Une résistance électrique 76 peut aussi tre insérée dans la base du radiateur 71 afin de réaliser un appoint de chaleur. FIG. 7 represents a radiator 71 made up of elements 72, screwed or welded, of cast iron, steel, aluminum or any other material and in which is inserted the exchanger tube 75 connected to the compressor by the tube 73 and connected to the condenser by the tube 74. An electrical resistor 76 can also be inserted in the base of the radiator 71 in order to provide additional heat.
