Abstract

The heat pump system has an exterior source formed by an air heat exchanger (20) connected in series with a buried collector (18). The order of the two is not important. The buried collector has a number of loops supplied in parallel from a distributor (17), which delivers a supply of water containing glycol anti-freeze to the loops. The water is circulated by a pump (29). The air exchanger has a fan (29) to drive air through the heat exchanger. The fan is regulated by a thermostat (21) measuring outside air temperature or the difference between the temperature of the fluid and the temperature of the outside air. An inversion valve (28) reverses operation for summer and winter cooling and heating.

Description

L'invention a pour objet une installation de chauffage et climatisation par thermopompe à capteur enterré couplée à un évaporateur extérieur à air. The subject of the invention is a heating and air conditioning installation by a buried sensor heat pump coupled to an outdoor air evaporator.

On connaît déjà des installations de pompe à chaleur à capteur enterré assurant le chauffage et la climatisation de maisons individuelles. Heat pump installations with a buried sensor are already known, providing heating and air conditioning for individual houses.

De telles installations ne sont pas entièrement satisfaisantes car elles conduisent à des consommations plus élevées lorsque la température de l'air extérieur est supérieure à celle de la terre, tout en diminuant de façon sensible le coefficient de performance de la machine ainsi que sa puissance calorifique. Such installations are not entirely satisfactory because they lead to higher consumption when the outside air temperature is higher than that of the ground, while significantly reducing the coefficient of performance of the machine as well as its calorific power. .

Ces systèmes présentent l'inconvénient en outre d'appauvrir thermiquement le sous sol, ce qui risque de poser des problèmes de gel du terrain.These systems also have the drawback of thermally depleting the subsoil, which risks posing problems of ground freezing.

On connaît également des thermopompes à évaporateur à air extérieur ventilé. There are also known heat pumps with ventilated outside air evaporator.

De telles installations ne sont pas entièrement satisfaisantes car elles nécessitent un dispositif de dégivrage et voient en outre leur performances thermiques et énergétiques diminuer au fur et à mesure que la température de l'air extérieur s'abaisse, imposant ainsi un autre dispositif de chauffage pour les temps froids. Such installations are not entirely satisfactory because they require a defrosting device and, moreover, see their thermal and energy performance decrease as the temperature of the outside air decreases, thus imposing another heating device for cold weather.

C'est d'une manière générale un but de l'invention de fournir une installation qui ne présente pas les inconvénients rappelés ci-dessus des installations connues. It is generally an object of the invention to provide an installation which does not have the drawbacks mentioned above of known installations.

C'est en particulier un but de l'invention de fournir une installation de thermopompe comportant un échangeur extérieur à air et un évaporateur sur capteur enterré placé en série.. It is in particular an object of the invention to provide a heat pump installation comprising an external air exchanger and an evaporator on a buried sensor placed in series.

C'est encore un but de l'invention de fournir une installation de thermopompe réversible permettant de climatiser les locaux en été et d'assurer en hiver le chauffage d'appoint des pièces de la zone jour le chauffage de base de la zone jour et le chauffage intégral de la zone nuit étant assurés par une seconde thermopompe à condensation à eau reliée à des radiateurs basse température ou à un plancher chauffant.  It is also an object of the invention to provide a reversible heat pump installation making it possible to cool the premises in summer and to provide additional heating in rooms in the day area in winter, basic heating in the day area and full heating of the sleeping area being provided by a second water-cooled heat pump connected to low temperature radiators or a heated floor.

Le dispositif s'incorpore par exemple dans une thermopompe à capteur enterré pour assurer le chauffage de maisons individuelles. The device is incorporated, for example, in a heat pump with an underground sensor for heating individual houses.

Le compresseur de la thermopompe est utilisé en hiver afin de prélever la chaleur de l'air extérieur puis de la terre et de la transférer dans le bâtiment par l'intermédiaire d'un ou plusieurs condenseurs à air et ou d'un condenseur à eau couplé à des radiateurs et à un plancher rayonnant à basse température. The compressor of the heat pump is used in winter to take heat from the outside air and then from the earth and transfer it to the building via one or more air condensers and or a water condenser. coupled with radiators and a radiant floor at low temperature.

C'est encore un but de l'invention de fournir un système de régulation permettant d'autoriser le fonctionnement de l'évaporateur à air lorsque les conditions climatiques de l'air extérieur sont plus favorables que celle du sol. It is also an object of the invention to provide a regulation system making it possible to authorize the operation of the air evaporator when the climatic conditions of the outside air are more favorable than that of the soil.

L'invention sera bien comprise par la description qui suit faite à titre d'exemple et en référence aux dessins annexés dans lequel:
û La figure 1 est un schéma d'une installation selon l'invention
û La figures 2 représente une installation selon l'invention comportant
une inversion de cycle permettant la climatisation en été et un
capteur enterré à circulation d'eau glycolée.The invention will be better understood from the following description given by way of example and with reference to the appended drawings in which:
û Figure 1 is a diagram of an installation according to the invention
û Figures 2 shows an installation according to the invention comprising
a cycle reversal allowing air conditioning in summer and a
buried sensor with brine circulation.

ù La figure 3 représente un schéma d'intégration de l'invention pour
le chauffage et la climatisation d'une maison individuelle.ù Figure 3 shows an integration diagram of the invention for
heating and air conditioning in a single house.

Un dispositif de thermopompe selon l'invention, figure 1 comporte un compresseur (10) refoulant par la tuyautene (24) dans un condenseur (11) de type à air ou à eau, le fluide frigorigène condensé se dirige dans le réservoir (12) par la tuyauterie (22). A heat pump device according to the invention, FIG. 1 comprises a compressor (10) discharging through the pipe (24) into a condenser (11) of the air or water type, the condensed refrigerant flows into the tank (12) by the piping (22).

La tuyauterie (15) distribue le liquide (14) vers le détendeur thermostatique (16) dont le bulbe (23) est placé sur la tuyauterie (26) d'aspiration du compresseur (10). Le liquide détendu se dirige vers l'évaporateur à air (20) dont le ventilateur de brassage (25) est commandé par un régulateur (21) qui pourra être soit un thermostat extérieur soit un thermostat différentiel comparant la température du fluide détendu à celle de l'air extérieur. Une première évaporation se produit dans l'évaporateur (20) si le ventilateur est autorisé, le fluide frigorigène se dirige ensuite vers le capteur enterré (18) par l'intermédiaire d'un distributeur (17) qui répartit le fluide vers les diverses boucles (18,, 182,... 18n) où se produit l'évaporation finale et la surchauffe du fluide frigorigène, le fluide gazeux est collecté par le collecteur(19) puis est renvoyé au compresseur par la tuyauterie (26). Dans une variante de la figure 1, le capteur enterré pourra être à circulation d'eau glycolée tel représenté figure 2
Un dispositif de thermopompe selon l'invention, figure 2 comporte un dispositif d'inversion de cycle (28) permettant d'inverser le rôle des échangeurs jouant le role d'évaporateur et de condenseur. Des clapets de retenue (13) et (23) ainsi que duaux détendeurs (16) et (27) permettent alors d'inverser le sens du fluide dans les conduites liquide. Dans la version représentée figure 2, le capteur enterré est à circulation d'eau glycolée ou d'un autre liquide incongelable pulsé par une pompe (29) afin de former échange thermique intermédiaire entre le capteur enterré constitué par des boucles (8r, 82,...8n) et le frigorigène en ébullition dans l'échangeur (18).The pipe (15) distributes the liquid (14) to the thermostatic expansion valve (16) whose bulb (23) is placed on the suction pipe (26) of the compressor (10). The expanded liquid goes to the air evaporator (20), the stirring fan (25) is controlled by a regulator (21) which may be either an external thermostat or a differential thermostat comparing the temperature of the expanded fluid to that of outside air. A first evaporation occurs in the evaporator (20) if the fan is enabled, the refrigerant then goes to the buried sensor (18) via a distributor (17) which distributes the fluid to the various loops (18 ,, 182, ... 18n) where the final evaporation and overheating of the refrigerant occurs, the gaseous fluid is collected by the manifold (19) then is returned to the compressor by the piping (26). In a variant of FIG. 1, the buried sensor may have circulation of brine water as shown in FIG. 2
A heat pump device according to the invention, FIG. 2 comprises a cycle reversing device (28) making it possible to reverse the role of the exchangers playing the role of evaporator and condenser. Check valves (13) and (23) as well as dual pressure reducers (16) and (27) then make it possible to reverse the direction of the fluid in the liquid lines. In the version shown in Figure 2, the buried sensor is circulating glycol water or other frost-resistant liquid pulsed by a pump (29) to form intermediate heat exchange between the buried sensor constituted by loops (8r, 82, ... 8n) and the refrigerant boiling in the exchanger (18).

L'échangeur (11) est ainsi évaporateur en cycle été, assurant la production de froid et condenseur en cycle hiver, assurant le chauffage. The exchanger (11) is thus evaporator in the summer cycle, ensuring the production of cold and condenser in the winter cycle, ensuring the heating.

Une installation utilisant l'invention, figure 3 comporte deux dispositifs de thermopompes tels que décrits figures 1 et 2. avec un ou plusieurs échangeurs à air (11a,....1 1an) alimentés par les tuyauteries (24a) et (22a) et un échangeur à eau alimenté par les tuyauteries (24e) et (22e), correspondant respectivement aux tuyauteries (24) et (22) des figures 1 et 2. Le circuit à échangeur à eau comporte une pompe de circulation (30) alimentant en eau chaude. par la tuyauterie (32), le plancher chauffant (36) par le collecteur (33) et le circuit de radiateurs (35,, 352.. ..35m, 35n) par le collecteur (34). Les différents retours d'eau radiateurs (40) et planchers (41) sont renvoyés à l'échangeur (île) par la tuyauterie (42). Un réchauffeur d'appoint (31) peut être ajouté sur le circuit de départ eau chaude. Dans un tel dispositif. le circuit à condenseur à air pourra servir de chauffage d'appoint pour la zone jour et assurer la climatisation été, et le circuit à condenseur à eau pourra servir de chauffage de base de la zone jour et de chauffage intégral de la zone nuit. Le circuit à eau pourra également être réversible et assurer la distribution d'eau fraîche en été vers le plancher rayonnant. An installation using the invention, FIG. 3 comprises two heat pump devices as described in FIGS. 1 and 2. with one or more air exchangers (11a, .... 1 1 year) supplied by the pipes (24a) and (22a) and a water exchanger supplied by the pipes (24e) and (22e), corresponding respectively to the pipes (24) and (22) of FIGS. 1 and 2. The water exchanger circuit comprises a circulation pump (30) supplying Hot water. by the piping (32), the heating floor (36) by the collector (33) and the radiator circuit (35 ,, 352 ... 35m, 35n) by the collector (34). The various radiators (40) and floors (41) water returns are returned to the exchanger (island) by the piping (42). A backup heater (31) can be added to the hot water flow circuit. In such a device. the air condenser circuit can be used as auxiliary heating for the day area and provide summer air conditioning, and the water condenser circuit can be used as basic heating for the day area and full heating for the night area. The water circuit may also be reversible and ensure the distribution of fresh water in summer to the radiant floor.

Le positionnement en série de l'échangeur à air et de l'échangeur à capteur enterré pourra être inversé, de telle manière qu'en cycle hiver,
I'évaporateur à air se trouvera placé en dernier dans le sens du fluide.The serial positioning of the air exchanger and the buried sensor exchanger can be reversed, so that in winter cycle,
The air evaporator will be placed last in the direction of the fluid.

L'invention n'est pas limitée aux thermopompes à capteurs enterrés, elle trouve son application également dans les systèmes de thermopompes à évaporateur à eau ou à air ainsi que dans les systèmes de récupération de chaleur ou de froid. The invention is not limited to heat pumps with buried sensors, it also finds its application in heat pump systems with water or air evaporator as well as in heat or cold recovery systems.

L'application principale de l'invention se situe dans les pompes à chaleur à capteurs enterrés assurant le chauffage et le rafraîchissement des habitations. The main application of the invention is in heat pumps with buried sensors ensuring the heating and cooling of dwellings.

II est possible d'utiliser l'invention dans les pompes à chaleur à condensation par eau ou par air ou dans le plancher, ainsi que dans les systèmes de refroidissement d'air à condensation à eau ou à air. It is possible to use the invention in water or air condensing heat pumps or in the floor, as well as in water or air condensing air cooling systems.

L'invention n'est pas limitée aux systèmes à compression, elle trouve en effet son application dans les machines à absorption (eau/bromure de lithium ou
NH3/eau par exemple), et encore dans les machines frigorifiques à réaction chimique et à adsorption. The invention is not limited to compression systems, it indeed finds its application in absorption machines (water / lithium bromide or
NH3 / water for example), and again in refrigeration machines with chemical reaction and adsorption.
