Description

Изобретение относитс к технике кондационировани воздуха.This invention relates to an air conditioning technique.

Известен кондиционер, содержащий корпус и установленный в нем пневматический пульсатор в виде двухмембранного пневморепе с последовательно расположенными контактами, образующими камеру, и обратной св зью, включающей теплообменник и регулирующий дроссель , расположенный на входе в пневмореле, и влагоотделитель 1.A conditioner is known, comprising a housing and a pneumatic pulsator mounted therein in the form of a two-membrane pneumorep with sequentially arranged contacts forming a chamber and a feedback connection including a heat exchanger and a control throttle located at the inlet of the pneumorel and moisture separator 1.

Недостатком известного кондиционера вл ютс больщие его габариты, обусловленные наличием обособленных элементов.A disadvantage of the known conditioner is its large size due to the presence of separate elements.

Цель изобретени - сокращени -габаритов.The purpose of the invention is to reduce the -size.

Поставленна цель достигаетс тем, что в корпусе установлен теплоизол ционный кожух, ограничивающий камеру и образующий с корпусом кольцевую полость, служающую теплообменником , а контакты выполнены нормально замкнутыми, и второй по ходу воздуха контакт расположен во влагоотделителе.The goal is achieved by the fact that a heat insulating casing is installed in the casing, bounding the chamber and forming an annular cavity with the casing, which serves as a heat exchanger, and the contacts are normally closed, and the second downstream contact is located in the moisture separator.

(54) КОНДИЦИОНЕР(54) AIR CONDITIONING

Кондиционер содержит корпус 1 и установленный в нем пневматический пульсатор в виде двухмембранного пневмореле 2 с последовательно расположенными контактами 3 и 4, образующими камеру 5, и обратной св зью 6, включающей теплообмен1шк 7 и регул1фующий дроссель 8, расположенный на входе в пневмореле 2, и влагоотделитель 9. В корпусе 1 установлен теплоизол ционный кожух 10, ограничивающий камеру 5 и образующий с корпусом 1 The air conditioner comprises a housing 1 and a pneumatic pulsator mounted therein in the form of a two-membrane pneumorele 2 with sequential contacts 3 and 4 forming the chamber 5 and feedback 6 including heat exchanger 7 and regulating choke 8 located at the inlet of the pneumorel 2 and moisture separator 9. In case 1, a heat insulating jacket 10 is installed, bounding chamber 5 and forming with case 1

10 кольцевую полость 11, служащую теплообменником , а контакты 3 и 4 выполнены нормально замкнутыми, второй по ходу воздуха контакт 4 расположен во влагоотдепителе 9. Кроме того, кондиционер имеет расширительную 10 annular cavity 11, which serves as a heat exchanger, and contacts 3 and 4 are made normally closed, the second along the air flow, contact 4 is located in the moisture-trap 9. In addition, the air conditioner has an expansion

15 камеру 12 во влагоотделктеле. Пневмореле 2 содержит мембранный блок, имеющий полый шток 13 с радиальнь1ми впускными отверсти ми 14, соплом 15 на торце и мембранами 16 и 17 с жесткими центрами 18 и 19. Причем 15 camera 12 in the moisture separator. Pneumorel 2 contains a membrane unit having a hollow rod 13 with radial inlet holes 14, a nozzle 15 at the end, and membranes 16 and 17 with rigid centers 18 and 19. And

Claims

20, the effective area of the membrane 16 is larger than the effective area of the membrane 17. Membranes with a relay casing are formed by power supply and control chambers 20 and 21. Spring. 22 squeeze 396 interacts with the rod 13 and the relay housing. The nozzle 15 at the inlet of the chamber 5 contacts with the first contact 3. At the exit of the chamber 5 there is a nozzle 23 with which the second contact 4 contacts the first rod 24 having a spring 25. At the inlet and outlet of the chamber 5, there is heat-insulated in the wall The casing 10 has openings 26 and 27, provided with plates 28 and 29 forming the outlet and inlet valves, respectively. The dehumidifier 9 is provided with a condensate discharge channel 30, the outlet 31 of which is directed towards the air conditioner body 1 in the area of the heat exchanger 7. The air conditioner has an inlet, a channel 32 and an output channel 33. The air conditioner operates as follows. Compressed air from the source enters through the inlet channel 32 of the air conditioner into the chamber 20 of the pneumorele 2 and through the inlet holes 14 into the internal channel of the hollow rod 13. The air pressure in the chamber 20 increases and due to the difference in the effective areas of the membranes 16 and 17, a force displaces the hollow rod 13 with membranes and a deforming spring 22. In this case, the nozzle 15 moves away from the contact 3 and the air enters the chamber 5. The air present in the chamber 5 at atmospheric pressure is compressed again by the incoming portion and is forced out through the inlets 27 and the plate 29 The cavity 11 of the heat exchanger 7, in which the excess heat is transferred to the housing 1. Simultaneously via feedback 6, through the regulating choke 8, air flows from the cavity 11 into the chamber 21. As the pressure increases, the force in the chamber 21 decreases on the hollow rod 13, caused by the difference in the effective areas of the membranes 16 and 17 and the pressures in chambers 20 and 21. In this case, the spring 22 expands and moves the naked brush 13 to the contact 3, presses the nozzle 15 to the latter and together with the force caused by the effective area of the nozzle 23 and pressure chamber 5, pushes contact 4 from nozzle 23. Air from the chamber: 5 through nozzle 23 enters the draining chamber 12. As air expands, its temperature decreases, excess (for a given temperature) water vapor and oils condense and retain in the air separator 9 ,. The cooled and drained air through the output channel 33 enters the consumer, for example, to the cooled miner's vest. The condensate, along with a certain amount of cooled air through the channel 30 through the outlet 31, is fed to the body 1 of the air conditioner, contributing to the heat removal. When the nozzle 23 is opened, after air escapes it, the chamber 5 receives air from the cavity 11 of the heat exchanger 7 through the openings 26 and plates 28 and from the chamber 21 through feedback 6 and the regulating throttle 8. When lowering in the chamber 21 to a level that provides forces due to the difference in effective areas of the membranes 16 and 17, sufficient to deform the spring 27, the hollow rod 13 will begin to move, and the nozzle 15 will detach from the contact 3, and contact 4 will close the nozzle 23 with the force of the spring 25. Later on, the process described above. The cooling capacity of the air conditioner is regulated by changing the time constant of the feedback channel by means of the control throttle 8. Proposed implementation; an air conditioner reduces its size and improves its reliability.
