Abstract

A flat envelope (1) of microporous material, mounted on, or below, transverse roof bars (8), is supplied with water from a header (6). Uniform circulation is encouraged by vertical fore-and-aft internal partitions; under each, externally, runs a closed tubular stiffener (4). A screen (9) shades the envelope from direct sunlight. Water cooled by evaporation is circulated (11, 12) by a pump (P) through the car heater heat-exchanger (R), the hot water connections being isolated by two-way valves (V). The heater fan (Ve), thermostatically controlled (Tc), circulates the cooled air. In a detachable variant, cooled air collected from the (open-ended stiffeners (4) is directed into the car by a window-mounted nozzle, opt., the envelope is in direct contact with the, unlined, roof.

Description

DESCRIPTION
La presente invention concerne un système de refroidissement ou de clima@@sation de lhabitacle de tout vehicule automobile.DESCRIPTION
The present invention relates to a cooling or air conditioning system of the passenger compartment of any motor vehicle.

base sur le refroidissement par evaporation dun volume d'eau contenu dans un reservoir micro poreux.based on evaporative cooling of a volume of water contained in a micro porous tank.

La climatisatton des vehicules particuliers fait actuellement appel å un groupe compresseur et un de tendeur. mais son installation sur un vehicule non equipe de serie nécessite une intervention In ate LIre e . dont le cout es ; li a1 ttatit De plus, ces climatiseurs sont consom mateurs d'energie. et ne peuvent entre montes que sur des moieurs ile puissance importante
Le système de chmatisation selon t'invention est un dispositif autonome et amovible peu co@feux et non consommateur d'énergie. constitue de deux parties principales: - un évaporateur: @ s agit d'un reservoir d'eau. de 20 litres environ. de Forme rectangula@ce adaptée au toit de la plupart des vehicules automobiles @t m x 1.50 m environ).Son enveloppe utilise un materiau souple micro poreux (tissu) à l'origine d'un t'lux capillaire d'eau de l'interieur vers l'exterieur
L'évaporation de cel@e pellicule d'eau. se ton les lois de la physique (gradient de temperature. hygrometrie et flux de l air ambiant) permet un refro@dissement de l'eau contenue dans le réservoir (540 Cal /g d'eau evapore). The air conditioning of private vehicles currently uses a compressor unit and a tensioner. but its installation on a non-serial vehicle requires In ate LIre intervention. whose costs are; li a1 ttatit In addition, these air conditioners consume energy. and can only go up on high power meors
The chmatization system according to the invention is an autonomous and removable device that is not very costly and does not consume energy. consists of two main parts: - an evaporator: @ s acts as a water tank. about 20 liters. Rectangular @ ce shape adapted to the roof of most motor vehicles @tmx 1.50 m approx.) Its envelope uses a flexible micro-porous material (fabric) causing a capillary flow of water from the interior outwards
Evaporation of this water film. according to the laws of physics (temperature gradient, humidity and ambient air flow) allows cooling of the water contained in the tank (540 Cal / g of evaporated water).

La seule intervention necessaire à La maintenance du dispositif est le remplissage du reservoir lorsque celui-ci est vide.The only intervention necessary for the maintenance of the device is the filling of the tank when it is empty.

L'utilisation d'eau froide permet une efficacite im mediate du système.The use of cold water allows immediate system efficiency.

- un échangeur thermique: une première version entièrement autonome. u@hse des tubes bons conducteurs thermiques taluminium par exemple@ suues longitudinalement sous le reservoir deau. et presentant une large surface d'échange avec ce dernier @ La circulation de l'air dans les tubes est assuree par le deplacement du vehicule. L'air se refroidit au contact de l'atuminium. lui-même refroidi par l'eau du réservoir. L air froid est coileete a ta sortie des tubes et canalisé vers l'habitacle par une manche a air souple. Dans cette configuration. le svsteme n est donc pas efficace a l'arrêt du vehicule. et @@ @@ @ pas des regulation de la temperature. - a heat exchanger: a first fully autonomous version. u @ hse good aluminum thermal conductor tubes for example @ run longitudinally under the water tank. and having a large exchange surface with the latter @ The circulation of air in the tubes is ensured by the displacement of the vehicle. The air cools in contact with the aluminum. itself cooled by water from the tank. The cold air is coiled at your exit from the tubes and channeled to the passenger compartment by a flexible air sleeve. In this configuration. the system is therefore not effective when the vehicle is stopped. and @@ @@ @ not temperature regulation.

Une deuxieme version, plus perforante, u@hse le radiateur de chauffage de l habnacle du vehicule comme echangeur thermique (cela necessne une intervention a son niveau). Le reservoir est raccorde par deux tuyaux souples au radiateur, l'eau y circule grace a une pompe (à rajouter). Cette version permet d'utihser les circuits de vent@ation qui equipent le vehcule. et un therostat commandant la pompe peut étre ajoute pour reguler la temperature de l'habitacle. En saison froide, le reservoir d'eau est deconnecte au niveau des tuyaux souples et retire. la pompe est laissee en place, le radiateur est raccorde au circuit d'eau chaude
Une version non amovible peut etre envtsagee. utilisant un reservoir fixe monte sur le tou ou sous le capot du vehicule.A second, more perforating version, uses the radiator for heating the passenger compartment of the vehicle as a heat exchanger (this requires intervention at its level). The tank is connected by two flexible pipes to the radiator, the water circulates there thanks to a pump (to be added). This version makes it possible to use the wind @ ation circuits which equip the vehicle. and a thermostat controlling the pump can be added to regulate the temperature of the passenger compartment. In the cold season, the water tank is disconnected at the flexible hoses and removed. the pump is left in place, the radiator is connected to the hot water circuit
A non-removable version can be stored. using a fixed tank mounted on all or under the hood of the vehicle.

L'échangeur thermique peut e C le radiateur de chauffage de l'habitacle selon la deuxieme version, ou le plafond du vehicule lui- me me Si le resservoir est pose dessus. Dans cette configuration. l'invention doit etre mtegree a la construction du véhicule; elle peut egnalement servtr de système de refroidisse ment pour la benne des fourgons de transport frigorifique. un ventillateur assurant l'evaporation de l'eau du rèservoir même à l'arrêt du vehicule.The heat exchanger can e C the radiator for heating the passenger compartment according to the second version, or the vehicle ceiling itself If the tank is placed on it. In this configuration. the invention must be incorporated into the construction of the vehicle; it can also be used as a cooling system for the body of refrigerated transport vans. a fan ensuring the evaporation of water from the tank even when the vehicle is stopped.

La version autonome est illustrée par la figure 1.The standalone version is illustrated in Figure 1.
