Description

In the proposed automobile, in a vacuum cooler, a mixture of gasoline and water vapor in the surface carburetor is sucked by the engine of the car and the mixture expanding in the radiators removes heat from the refrigeration room, which is ventilated by means of a gas injector connected to exhaust pipes equipped with exhaust gases. In a modification of a car with a vacuum refrigerator, pipes with a coil circulating in them, cooled by a coil, are used to absorb heat from the refrigeration room, when the mixture of gasoline vapor and water sucked into the engine cylinder in the latter is expanded.

In FIG. 1 shows a longitudinal section, of a car with a refrigerator; FIG. 2, a perspective view of a vacuum refrigerator; FIG. 3-scheme of its modification.

The refrigerant agent is gasoline, which is also designed to operate the engine / car and is placed in a gas tank 14 (Fig. 1 and

23

2), from where it is supplied under pressure in the usual way to the surface carburetor 77 located under the ceiling of the refrigerator, or below, by means of an air hand pump 77, or by the pressure of exhausted gazrv, by means of a pressure reducing valve, not shown in the drawing. 5 The surface carburetor 77 consists of two chambers, one of which houses a cylindrical float cap with a needle valve that controls the flow of gasoline from above. Water is placed in the adjacent chamber, which can be supplied by various existing methods, and is also regulated by a dropping device (not shown in the drawing).

The air in the gasoline chamber, under the influence of vacuum, enters through the receiving pipe 72, which passes through a layer of adjustable gasoline, depending on the immersion of the float and the elongation of the hood walls. Then the mixture of air with gasoline vapors passes through a layer of water and is saturated with water vapor, while simultaneously cooling somewhat, at which the volume of gas decreases. A mixture of gasoline and water vapor

the outlet from the surface carburetor // enters the system of special radiators 23 connected in series by pipelines 22 and located under the ceiling and from the sides of the refrigeration room. Under the influence of strong vacuum when the engine is running, when it is suctioned, the mixture expands, lowering the temperature, which is quickly transmitted to the metal walls of the radiator, which in turn removes heat from the mixture of vapor inside them.

The radiators - refrigerators 23 consist of two channels. copper sheets, interlaid between each other, between which a metal mesh is placed, forming a triangular chamber, on which the mixture moves in a wave-like manner, improving the movement of gasoline vapor with air and water vapor and rendering the metal faster than cold. - The cooled mixture due to the rapid evaporation of gases enters through pipelines / into the heating apparatus, equipped with a valve 6, designed to adjust the temperature of the mixture through an internal valve that covers, alternately, two orifices of the heating chamber 4, or the mixing tube 5, on which the mixture can be cold. The mixture then passes through a safety valve 3 designed to protect the radiator from explosions during the frequent firing of the carburetor, all the way. stack poor mixture, i.e. when there is a slow burning process.

. The safety valve 3 is based on the principle of the “Davy” system lamp with two safety grids and valves, which serves to exhaust its gases in the connecting pipe between the carburetor and the motor. The mixture is heated in the preheating chamber 4 from exhaust gases, where exhaust gas and gasoline tubes pass in the same chamber. The adjustment of the gas mixture is done by hand with screw attachment 9, 8 and a lever with a corresponding pull spring. For ventilation of refrigeration there is a pipe 20

with two receiving funnels located under the ceiling 2 /, through which air is sucked in by a gas injector 19, acting through exhaust gases. This achieves at the same time fully secured mixing of air layers inside a refrigerated room having different temperatures. To reduce the effect of injection, there is a valve. 25, for the free release of gases in addition to a silencer.

The refrigeration room is a conventional construction brake consisting of two layers of oiled cardboard, between which is placed a 9LAY pressed and finely grained cork; all together sheathed on both sides with shawls located mutually perpendicularly. The roof of the cold room is covered with a porous sheeting on which the second metal roof is placed; tarpaulin contributes to the absorption of solar heat and the rapid evaporation of water particles; which is occasionally sprayed with a piping system and a pressurized water tank.

For ventilation, instead of the gas injector 19, it can be installed at the top, i.e. on top of the roof, air, whose action comes from the movement of the car.

In a modification of a car with a vacuum refrigerator, shown in FIG. 3, the cooling is transmitted through pipes with circulating X in them with a corresponding brine cooled by the refrigerator coil 9, under vacuum, which is obtained by the operation of the gasoline engine during suction, unlike direct refrigeration, by the refrigerator, to the air inside the refrigeration room.

The refrigerator coil 9 is placed in a separate tank (7) filled with brine and connected to a surface carburetor, which is powered by gasoline from a car tank 14, intended to be supplied with a combustible motor. Gasoline is supplied under pressure from the air pump 16 through the air duct 15 and the gasoline ducts 75 and 26. Air intended for mixing

SI, is sucked through a trz pipeline 12, which passes through a layer of gasoline surface carburerra //, and then through a layer of water that is in the same carburetor tank, saturated with gasoline and water vapor and simultaneously cooled somewhat and reducing the specific volume of gas. From the coil 9 of the refrigerator, the mixture enters the heater b, having a bypass channel 7 through the regulating channel 8 with a rifle and lever gear 27, 28 29. Then the mixture of vapors passes through the safety valve 5 into the caburator 3 by the engine through the cylinder /, during operation last during the first suction stroke. Exhaust gases, the output from the motor, enter the silencer 22 through the heater 6 and the gas injector 2G. The latter is designed to ventilate the refrigeration room with suction of air, as well as moist vapor inside the room, by means of a pipe 24 and receiving hoppers 23 located under the ceiling of the refrigeration room. The cooling of the room refrigerator is achieved

by brine circulating through pipes 19, located under the ceiling of the room and connected by pipeline 18, to reservoir 77.

The subject matter of the invention.
