Definitions
- the present invention relates to a circuit for generating cold or heat with a compressor, an evaporator, a condenser and a throttle element designed as a separate component with a fixed Flow cross-section.
- throttling devices are used in refrigeration circuits with a fixed flow cross-section.
- the throttling organs are, for example, by a copper tube arranged in a housing formed, the housing at the appropriate point in the Cooling circuit is switched on, in particular between the condenser and evaporator.
- the invention has for its object a circuit of the beginning to improve the type mentioned. In particular, the manufacturing effort and the manufacturing cost can be reduced.
- the throttle element can, for example, be a disk with a central one in particular Passage opening may be formed or at least one Have the disc as a component.
- This can be suitably between two elements of the circuit and only by connecting the two elements be fixed. This can be done between the two elements corresponding paragraph can be provided on which the disc rests. This results in both a constructive and a manufacturing process forth favorable design.
- Throttle device also serves as a sealing element for sealing the connection point of the two elements of the circuit are formed outwards.
- On separate sealing element for sealing the two elements against each other can therefore be omitted, so that a total of at least one more Component is saved. It can be inexpensive and inexpensive Way an external tightness of the circuit at the connection of the both elements are created.
- a another option is to insert at least one into the throttle body elastic sealing element, for example to use an O-ring.
- the throttle member be designed as a metallic seal or a metallic seal exhibit. This configuration is particularly suitable for high pressures.
- the throttle element can additionally or alternatively to the sealing function be designed with a filter function. This can also be a separate component saved and can reduce costs accordingly become.
- the throttle element can be on one side, in particular the inflow side, wear a filter screen to prevent the throttle from becoming clogged with dirt particles to prevent.
- the throttle body can also on both Wear such a filter screen on both sides, i.e. both on the inflow side and also on the downstream side. This can cause clogging even when it is at a standstill of the circuit from the downstream side can be prevented.
- an operation of the circuit in both Flow directions for example both as a refrigeration cycle and also take place as a heat pump.
- the throttle body is after a Special embodiment of the invention can be flowed through in both directions educated.
- the throttle element shown in Fig. 1 is a disk 1 with a central one Passage opening 2 formed.
- the passage opening 2 gives the throttle cross section before and will be trained accordingly.
- the disc 1 are two annular sealing elements on both flat sides 3 used.
- the disc 1 could have a surface made of elastic Have sealing material. Through both measures, the Washer 1 can be used as a sealing element.
- the disc 1 is, for example, between two pipe ends of the Circuit or, for example, between a pipe end and a connecting piece used, with a paragraph on one of the two elements is formed against which the disc 1 from the front of the other Element is pushed when the two elements are connected are.
- the connection of the two elements can, for example, by Screw in or through a flange connection.
- Fig. 2 shows a variant in which the throttle body additionally one Has filter function.
- the throttle body additionally one Has filter function.
- the disc 1 Filter sieve 4 arranged, which as counter to the flow direction I conical basket is formed.
- the disc 1 is at this variant also on the inflow side with an extension 5 formed, to which the filter screen 4 is attached and which with an in Flow direction I tapered inlet funnel 6 for the Passage opening 2 is provided.
- the disk 1 also has an annular ring on both of its flat sides Sealing element 3, which is inserted into a corresponding groove, so that there is a triple function here, namely in addition to the throttle function through the passage opening 2, a sealing function and a filter function.
- the disk 1 could also be used again be provided with a surface made of elastic sealing material.
- Fig. 3 also shows a throttle body additional filter function.
- Fig. 2 shows a throttle body additional filter function.
- Fig. 2 shows both sides of the disc 1 filter screens 4, 7 arranged. In this way can clog the passage opening 2 both from the inflow side as well as be prevented from the opposite side, or the throttle body can be used for both flow directions I and II become.
- the disc 1 has this Variant on both flat sides each have an extension 5, 8. Both Extensions 5, 8 are each with an inlet or outlet funnel 6, 9 for the passage opening 2 provided.
- Disc 1 moreover, an annular one on each of its two flat sides Sealing element 3, which is inserted into a corresponding groove, or a surface made of elastic sealing material, so that this variant fulfills a triple function, namely a throttle function by the Passage opening 2, a sealing function and a filter function.
- Fig. 4 shows a pipe end 10 and a connecting piece 11 of an inventive Circuit, the connection point in particular between the condenser and the evaporator.
- the end of the tube 10 has a section 12 with a reduced cross-section, which into a corresponding opening 13 of the connecting piece 11 engages.
- the opening 13 goes inwards into an opening 14 opposite the opening 13 reduced opening cross section over. This will distinguish between the Openings 13 and 14 formed a shoulder 15 facing the pipe end 10.
- a socket-like Throttle body 16 used, which on its to the connecting pipe 10 facing side is expanded like a disc.
- the disc-like Section 17 of the throttle member 16 has a diameter that is slightly smaller than the diameter of the opening 13. Also points the bushing section 18 of the throttle member 16 has a diameter, which is slightly smaller than the diameter of the opening 14. On this way, the throttle element 16 with the bushing section 18 Opening 14 are used and located on the paragraph 15 between the Support openings 13 and 14.
- the thickness d of the disk-shaped section 17 of the throttle element 16 is also chosen so that the tube 10 in its final installation position the disk-shaped section 17 of the throttle element 16 with its Presses end 12 against paragraph 15. In the illustrated embodiment this makes two in the two flat sides of the disc-shaped Section 17 inserted annular sealing elements 3 compressed. On this way can between the disc-shaped portion 17 and Connection piece 11 and between the disc-shaped section 17th and a section 12 of the tube 10 a seal can be realized, so that overall the connection point between the tube 10 and the Connection piece 11 is sealed to the outside. Additionally or alternatively could be between the tube 10 and the connector 11 O-rings be provided, which are inserted into corresponding grooves of the tube 10 are.
- the bushing section 18 and the disk section 17 of the throttle body 16 are formed with a central passage opening 22 in which is a deformed tube 23 is used.
- the tube 23 is in the Center surrounded by an O-ring 24, which by the shape of the Tube 23 is pressed against the passage opening 22 and thereby Pipe 23 seals against the bushing section 18 of the throttle member 16.
- the tube 23 is formed in such a way that it is in the middle, ie in the area of the O-ring 24, a passage opening 2 with the desired passage cross section as well as an inlet or outlet funnel on each side 25 forms for the passage opening 2.
- the tube 23 is flanged to the outside and lies on the end faces 26 of the throttle body 16.
- a filter sieve 4, 7 designed in accordance with FIGS. 2 and 3 so that the tapered closed ends of the Point filter sieves 4, 7 away from each other.
- the flow direction can be chosen according to arrow I or arrow II, since that Throttle body 16 is equipped on both sides with a sieve 4, 7. Any disassembly required is carried out in the reverse order.
- the throttle element according to the invention can be used to save space and inexpensive to manufacture.
- up to three functions can be Throttle function, sealing function and sieve function can be realized. Also this can save further costs and space.
