Abstract

The evaporator consists of parallel finned tubes (1) which are contained in an enclosure (4) covering one side of the evaporator and the top and bottom as well as the edges. The enclosure is completed by a sheet of glass (3) which is exposed to solar rays. The inside of the container is fitted with a perforated plate (6) to even out the air flow from the electric fan (2). Openings (5) equally spaced around the edge allow natural air flow across the evaporator.

Description

La présente invention concerne l'élément " évaporateur " d'une pompe à chaleur . The present invention relates to the "evaporator" element of a heat pump.

Les pompes 4 chaleur destinées au chauffage comprennent : un groupe frigorifique; un condenseur de fluide frigorigène à air ou à eaui destiné à produire la chaleur utile sous forme d'air de chauffage ou d'eau de chauffage ( ou autre fluide ) ; un ddtendeur; un évaporateur
L'évaporateur est destiné à rejeter le froid produit par le groupe frigorifique en contre-partie de la chaleur utile produite .Ce froid est habituellement rejet8, soit dans l'air extdrieur à l'aide d'un groupe comprenant une batterie de tubes à ailettes et un ventilateur placés dans un caisson, soit dans de l'eau ou autre liquide à l'aide d'un échangeur comprenant un serpentin noyé dans l'enceinte contenant l'eaux cette eau êtant soit perdue, soit recyclée .Dans ce dernier cas l'eau recycle peut être réchauffée par passage dans des capteurs solaires, ou simplement dans des tubes placés à quelques centimstres en dessous d'une aire ensoleille, ou encore dans des aaux ou fluides dont la chaleur peut Qtre récupérée
Les eaux de rivière et les fluides dont la chaleur est récupé- rable sont les meilleures sources n froides" disponibles et il est difficile de les concurrencer. mais il n'y en a pas partout.The 4 heat pumps for heating include: a refrigeration unit; an air or water refrigerant condenser intended to produce useful heat in the form of heating air or heating water (or other fluid); a regulator; an evaporator
The evaporator is intended to reject the cold produced by the refrigeration unit in return for the useful heat produced. This cold is usually discharged8, either into the outside air using a group comprising a battery of tubes fins and a fan placed in a box, either in water or another liquid using an exchanger comprising a coil embedded in the enclosure containing the water, this water being either lost or recycled. In this case, the recycled water can be heated by passage through solar collectors, or simply in tubes placed a few centimeters below a sunny area, or in water or fluids from which the heat can be recovered.
River water and heat-recoverable fluids are the best cold sources available and difficult to compete with, but not everywhere.

On fait alors appel à l'air extérieur ou au soleil, ce qui présente les inconvénients suivants : - l'air exterieur est souvent trop froid pour que le fonctionnement de
la pompe à chaleur soit dconomique - le soleil n'est prisent qu'une partie de la journée
C'est pourquoi la présente invention a pour objet de faire appel comme " source froide " aux aliments naturels suivants - le soleil - l'sir extérieur avec la vapeur d'eau qu'il contient - éventuellement la pluie
Sur ces bases j'ai déposé le 25 mai 1979 sous N 79 13937 une demande de brevet d'invention pour un capteur-évaporateur statique et pour un dispositif optimisant de fonctionnement
I1 'est apparu qu'unie solution dynamique pouvait ouvrir la voie à des applications plus étendues . C'est pourquoi, sans revenir sur le système d'optimisation qui reste valable dans le cadre de la présente demande de brevet d'invention, j'indique que l'objectif de la présente invention est atteint par = un groupe batterie-ventilateur 1-2 , voir planche unique , formant
évaporateur d'un système de pompe à chaleur, coiffe par un capteur
solaire plan vitre 3 - la batterie de tubes à ailettes I ou dispositif dquivalent, est
oridttée vers le soleil, la batterie étant très largement dimen-
sionnée en vue d'offrir une grande surface au rayonnement solaire
4 - le cadre préripherique du capteur est perforé d'orifices 5 pour
permettre l'entrée d'air extérieur dans le groupe batterie-ventilateur - en avant ou en arrière de la batterie est placé un répartiteur d'air 5
destine à égaliser le passage d'air à travers toute la surface de la
batterie - le moto-ventilateur 2 est placé à l'arrière du système
Le capteur-évaporateur fonctionne de la façon suivants s - la batterie reçoit directement la chaleur du rayonnement solaire direct,
indirect et réfléchi par le vitrage - elle prélève en outre de le chaleur dans l'air ventilé à travers le
système, tant la chaleur sensible de l'air que la chaleur latente de
condensation de la vapeur d'eau contenue dans l'air , éventuellement
la chaleur de solidification de 11 eau condensez, le givre formé pou
vant fondre par la suite sous l'effet du rayonnement solaire - lorsque l'ensoleillement est suffisant , le moto-ventilateur peut entre
arrêté .The outside air or the sun are then used, which has the following drawbacks: - the outside air is often too cold for the operation of
the heat pump is economical - the sun is only present part of the day
This is why the present invention aims to use as "cold source" the following natural foods - the sun - the outside air with the water vapor it contains - possibly rain
On these bases I deposited on May 25, 1979 under N 79 13937 a patent application for an invention for a static sensor-evaporator and for a device optimizing operation
It appeared that a dynamic solution could open the way to wider applications. This is why, without returning to the optimization system which remains valid within the framework of the present patent application, I indicate that the objective of the present invention is achieved by = a battery-fan group 1 -2, see single plate, forming
evaporator of a heat pump system, capped by a sensor
solar glass pane 3 - the finned tube bank I or equivalent device, is
oriented towards the sun, the battery being very largely dimen-
sioned in order to provide a large area for solar radiation
4 - the peripheral frame of the sensor is perforated with holes 5 for
allow outside air to enter the battery-fan group - in front of or behind the battery is an air distributor 5
intended to equalize the passage of air through the entire surface of the
battery - motor fan 2 is placed at the rear of the system
The sensor-evaporator works in the following way s - the battery directly receives heat from direct solar radiation,
indirect and reflected by the glazing - it also draws heat from the air ventilated through the
system, both the sensible heat of the air and the latent heat of
condensation of water vapor in the air, possibly
the heat of solidification of 11 water condense, the frost formed for
before melting under the effect of solar radiation - when the sun is sufficient, the fan motor can
stopped .

De jour l'ensemble de pompe à chaleur fonctionne en utilisant une énergie électrique chère ( tarif de jour ) mais a un coefficient de performance correspondant à une source de chaleur à potentiel élevé . During the day, the heat pump assembly operates using expensive electrical energy (day rate) but has a performance coefficient corresponding to a heat source with high potential.

De nuit le coefficient de performance du système pompe à chaleur est moins bon mais le système utilise une anergie moins chère ( tarif de nuit )
Une variante consiste à ne pas mettre en place le capteur solaire
Dans ce cas la pluie peut être utilisée comme source de chaleur auxiliaire; cette variante est intdressante dans les régions à forte pluviosits et faible ensoleillement
Le fait de pouvoir utiliser le système deux fois par jour permet de redire l'importance du stockage de chaleur , stockage qui f me relais entra la pompe à chaleur et l'utilisation
Le dispositif objet de l'invention est destiné à servir de " source froide de chaleur " à un système quelconque de pompe à chaleur At night the coefficient of performance of the heat pump system is less good but the system uses a cheaper anergy (night tariff)
A variant consists in not installing the solar collector
In this case rain can be used as an auxiliary heat source; this variant is attractive in regions with high rainfall and low sunshine
The fact of being able to use the system twice a day makes it possible to reiterate the importance of heat storage, storage which f me relay between the heat pump and the use
The device which is the subject of the invention is intended to serve as a "cold source of heat" for any heat pump system
