Description

The invention relates to means for diving operations, in particular to devices for conditioning the gaseous medium of diving pressure chambers, and can be used both in separate pressure chambers and as part of mobile and stationary diving complexes.

Known air conditioning diving pressure chambers, consisting of a fan, radiator, heater, fittings and pipelines [1] (prototype). When the fans are turned on, the gaseous medium passes through the radiator, in which cold water from the water supply constantly circulates, cooling the gaseous medium and condensing moisture from it. A shut-off valve is installed to drain the condensate. Further, the dried and cooled gaseous medium passes through electric heaters. To control the temperature in the device, it is possible to turn off both the radiator and the heaters. The air conditioning device is located inside the pressure chamber under the bed.

The disadvantage of this air conditioning device of the diving pressure chamber is the ineffective cooling of the gaseous medium in the summer, using a radiator using tap water. In addition, this device is placed inside the pressure chambers, which reduces fire safety, and also the specified device occupies a useful internal volume in which other equipment (sanitary and household devices, emergency breathing devices, etc.) could be placed.

The objective of the invention is to improve the safety and comfort of divers during the summer period inside the pressure chamber due to the effective cooling of the gaseous medium and the location of the device outside the pressure chamber.

The task is achieved by the fact that in the air conditioning device for diving pressure chambers, consisting of a fan, radiator, heater, fittings and pipelines, according to the utility model, the radiator is made on the basis of a plate of Peltier thermoelectric elements, longitudinally located inside the sealed housing and dividing this housing in half, in one half parallel to the plate of Peltier thermoelectric elements and in direct contact with it is a metal plate with cooling fins, and in the other half - a similar plate with heating fins, while this half of the body is connected by pipelines to a heater and to a source of cold water, and the entire device is located outside the pressure chamber .

The technical result from the use of the invention is to improve safety and comfort during its operation.

The scheme of the described conditioning device is shown in Fig. 1, and in Fig. 2 is a schematic view of the radiator.

The air conditioning device for diving pressure chambers (Fig. 1) consists of a fan 1 and a radiator 2, the internal cavity of which is divided by a longitudinally located plate of Peltier thermoelectric elements 3 into two parts, air 4 and water 5. At the same time, the air part 4 of the radiator 2 is connected to the fan from one end 1, and on the other - pipelines through a three-way valve 6 and a shut-off valve 7 with a pressure chamber 8, as well as through a three-way valve 6 with a heater 9. The heater 9, in turn, is connected through a non-return shut-off valve 10 and a shut-off valve 7 with a pressure chamber 8 , which is connected through a pipeline with a shut-off valve 11 to a fan 1. In addition, the air part 4 of the radiator 2 is equipped with a condensate drain pipeline with a shut-off valve 12.

The water part 5 of the radiator 2 is connected from one end through the water supply pipeline with a shut-off valve 13 to the water supply (cold water supply source), and from the other - through the pipeline with the shut-off valve 14 to the heater 9. The heater 9, in turn, is connected through a three-way valve 15 with a bypass pipeline and a pump 16 installed on it into the water supply pipeline or by appropriately switching the valve 15 to connect the heater 9 to the water drain pipeline.

The radiator (Fig. 2) consists of a sealed housing 17, the internal cavity of which is longitudinally divided into two sealed halves 4 and 5 by a plate of Peltier thermoelectric elements 3. In one half (air) 4, a metal plate 18 is located parallel to the plate 3 and in direct contact with it with cooling fins 19. In the other half (water) 5 there is a similar plate 20 with heating fins 21. Ribs 21 also serve as water flow guides.

The air conditioning diving pressure chambers works as follows.

After placing the divers in the pressure chamber 8 and raising the pressure in it, shut-off valves 7 and 11 open, and the Peltier thermoelectric elements and fan 1 are connected to the power source. The plate of thermoelectric Peltier elements 3 is cooled from the side of the air part 4 of the radiator 2 and heated from the other - the water part 5 of the radiator 2. In this case, the plate 3 cools the metal plate 18 with cooling fins 19 and heats the metal plate 20 with heating fins 21. The shut-off valve 13 opens and cold water from the water supply enters the water part 5 of the radiator 2, where it is heated. The heated water through the shut-off valve 14 enters the heater coil 9 and then to the three-way valve 15. If it is necessary to increase the temperature of the gas medium, the shut-off valve 13 closes and the pump 16 turns on, after which the water is sent through the bypass pipeline to the water supply pipeline and again to the water part 5 radiator 2. In other cases, the water is directed to the drain by a three-way valve 15.

The gaseous medium (air, artificial respiratory gas mixture) from the pressure chamber 8 through a pipeline with a shut-off valve 11 enters the fan 1, which circulates the gaseous medium through the device. After the fan 1, the gas medium enters the air part 4 of the radiator 2, where it is cooled, washing the plate 18 with cooling fins 19. The moisture released during the cooling of the gas medium is periodically removed from the radiator 2 through the condensate drain shut-off valve 12.

In summertime or if it is necessary only to cool the gaseous medium in the pressure chamber, it flows from the radiator 2 to the three-way valve 6, which opens towards the shut-off valve 7 and the cooled gaseous medium enters the pressure chamber 8.

In winter, or if it is necessary to heat the gas medium, the three-way valve 6 opens towards the heater 9, in which it is heated. Further, the gaseous medium enters pressure chamber 8 through non-return shut-off valve 10 and shut-off valve 7.

The layout of the described device for conditioning diving pressure chambers was made and tested during research to justify the development of a gaseous medium conditioning system for compartments of pressure chambers of the PDK type. According to its technical parameters, the device makes it possible to increase the safety and comfort of divers in the pressure chamber, in contrast to the device adopted as a prototype. The device provides increased fire safety and increased functionality of the internal volume of the pressure chamber due to placement outside the pressure chamber. The efficiency of cooling the gaseous medium increases indefinitely, since the overall dimensions of the device are not limited by the pressure chamber. In addition, this device is cheaper to operate.
