FR2679017A1 - Portable air-conditioner for cars and small dwellings, with permanent version complementing (completing) a freezer - Google Patents

Abstract

Portable air-conditioner for cars and small dwellings according to the invention. Having the shape of a briefcase in the preferred embodiment, it is made up of an extensible rubber pouch (21) containing a previously-frozen coldness accumulator (20). This pouch is inflated by an electric pump on one side and expels cooled compressed air on the other side towards an orientable cylindrical diffuser (1). The pouch and coldness accumulator assembly is contained in a high-performance isothermal container. In a version intended to complement a conventional freezer, the pump and elastic pouch are on the outside, whereas the coldness accumulator, placed in the freezer, is made up of a flat container filled with cooling liquid and traversed internally by a long and winding tube, the fresh air content of which is pulsed towards the outside.

Description

Portable air conditioner for automobiles and small habltations according to the invention.

Air conditioning, highly appreciated by the public, however, conventionally requires expensive equipment and remains for use often episodic, even occasional, as is the case for automotive air conditioning used only when moving the vehicle in hot weather.

The air fresheners with water tank are not satisfactory because of insufficient power and autonomy.

The portable air conditioner according to the invention is intended to remedy this problem by answering by the provision of a provision of an air conditioning, to the high performance map all being economic.Ceci becoming possible thanks to considerable progress in thermal insulation and coolants
The portable air conditioner according to the invention having, in the preferred embodiment, the form of a rectangular binder, consists of an expandable rubber bag containing a previously frozen cold accumulator.

d'utilisation déterminée)
La poche élastique,contenant exactemeng,à l'état initial ltaccumulateur de frcid,est enfermée dans une boite isotherme perforn-lante,ou elle est entourée d'un éspace-libre en prévision de son gonflage. Lors du gonflage cet espace libre se réduira avec compression de l'air quril contient.This bag is inflated by an electric pump, on one side and expels on the other compressed air refreshed in contact with the cold accumulator. The set pocket and cold accumulator is contained in a container ISOTHERME performance
Incidentally, the cold accumulator, once exhausted, may be replaced or accompanied by water. The portable air conditioner will then be converted into an air freshener, until a refill accumulator is installed.

determined use)
The elastic bag, containing, exactly, the initial state of the accumulator, is enclosed in a perforated isothermal box, or it is surrounded by a space-free in anticipation of its inflation. During inflation this free space will be reduced with compression of the air that contains it.

The characteristics of the whole being cabled so that it does not have any kind to the operation of the air conditioner.

An air inlet pipe from the pump opens into the pocket by a non-return valve located in the isothermal coating thickness and also studied in the direction of a minimization of heat exchange abev outside .

Inlet tubing is equipped with a safety valve
From the pocket, a second tube ends at the end
at the level of an air diffuser.On the path of this
tubing, in the thickness of the isothermal coating is placed, a
second non-return valve regulated so as not to allow
the air only if sufficient pressure settles in the pocket
which will thus be kept inflated permanently during the
air conditioner? The flow of fresh air out is such
that the air stays long enough in the pocket to
refreshing yourself in contact with a sufficiently cold accumulator rand introduced beforehand on the side of the pocket which contains
a wide lateral opening hermetically closed by a
thick insulating cover secured by two strong bolts tight to
the hand.

An electric pump ensures the arrival of the air it breathes from the outside through Wn dust filter
It is designed for minimal heat production.

It receives its power supply by connection, either
on the cigarette lighter or the vehicle contact, that is, in use
domestic, on the sector thanks to a power supply with
transformer.The electrical supply is dependent on a
switch of a speed variator; and a thermostat
atmosphere.

The cold accumulator consists of several plates
with corrugated surface arranged and fixed, a few millimeters
each contains a refreshing liquid
fast freezing and very strong storage capacity of
cold.The set has a large contact area with
the air contained in the pocket.

The air conditioner delivers fresh air through a diffuser
cylindrical located on one of its long sides and orientable
about 2800 approximately, around its axis thanks to the knobs located at its ends. The air leaves by orifices located on the same straight line. The diffuser is encaged by a ring of
width varying in STAIRCASE and used to concentrate the FLUX of air thanks to a rotary positioning.

 Once this adjustment is made the orientation interests diffuser and ring solidarily.

 The portable air conditioner has a shoulder strap and a folding handle.

For use in the upright position the base has two pairs of tabs laterally deplayable.

In another embodiment the portable air conditioner is very miniaturized and powered by a rechargable battery.

The fresh air is expelled through a tubing that divides into thinner tubings ending in the armpits, back and crotch of the person wearing this air conditioner slung under or on the outer garment. thin pipes are carried by a structure having the general shape of the trunk, on which is provided a connection site of the main tubing exiting the air conditioner.

In another embodiment, a tube leaves the air conditioner, miniaturized and slid in a pochc, and leads to a cylindrical diffuser, the thickness of a pencil, installed transversely on the root of the nose of the user and stabilized by two branches analogous to those of a pair of glasses.If the user wears glasses, the diffuser will be fixed simply on the top of the frame
Outgoing fresh air is directed at the wearer's forehead.

This is particularly useful-for some jobs, especially for surgeons who usually have to be permanently bled forint.
In one embodiment, alternatively the cold accumulator is based on liquid heel. The special nature of this technology and its short reserve it for specific applications.

 In another embodiment, the assembly is adapted to a freezer.

The air pumping device and the elastic bag: are located outside (above EX) of the freezer while the cold accumulator is placed under the roof of the conge latteur.Cet accumulator consists of a a large, fairly flat container filled with a quick-freezing coolant type icy for automobiles. It is traversed by a very long and very sinuous :: metal pipe describing a series of U tight one presid others and browsing each the entire width of the container.This pipe to a surfacc significantly enlarged by visible concavity corrugations cn tranversale
The air blown from the outside by the elastic bag under pressure at the time to refresh by browsing latubulure and out at a ventilation grille next to which fiqure a control panel with main switch, speed variator , room thermostat and indicator light to turn on the power.

The liquid from the frozen container will act as a buffer to allow the cold to be gently removed to affect the temperature of the freezer which is indirectly biased and in a very spreadable manner. The freezer will therefore continue to function as a freezer. as usual.

Structurally the only change in the freezer is the making of two small gutters or
ORIFICES intended to let the tubes of entry and exit of air.

The device according to the invention is intended to refresh the temperature of a passenger compartment of reduced volume The goal will be achieved thanks to a quality insulation using high performance materials The article achievesreferring to specific needs for a cost price very interesting
Very flexible use in a volume and format that can be adapted to each application, it can interresseRégalement sites (workplaces particularly exposed to heat such as welders ect ...) and, in a reduced format, singing speakers, MOTARDSvestivants, ect. .The embodiment,
REMOVABLE or permanent, intended to complement freezers and refrigerators, is particularly interesting for res studios, small dwellings and kitchens.

Occupants, often with modest incomes, will benefit from efficient air-conditioning without major expense or major work without compromising the operation of the main unit.
