Definitions
- the invention relates to a double-acting refrigerant compressor.
- the required compressors must in this case generate a gas pressure in the bottle, which is above the vapor pressure of the refrigerant at the respective ambient temperatures. This gas pressure can exceed significantly in extreme cases which exceed 30 bar, so that for the further assumptions of a working pressure up to 40bar is assumed.
- the recycling device In known recycling devices for transferring the refrigerant from a refrigeration system into a recycling container, the recycling device is provided with a compressor and a compressor bypassing the bypass line.
- the compressor line and the bypass line are each provided with valves, wherein initially the pressurized refrigerant flows through the bypass line into the recycling container. After pressure equalization between recycling container and refrigeration system, the remaining refrigerant is transferred via the compressor of the recycling device in the recycling container, the bypass line is closed.
- the invention has for its object to provide a refrigerant compressor with simple and inexpensive construction and with the required for the refrigerant recovery high compression performance.
- the refrigerant compressor is defined by the features of claim 1. Accordingly, the refrigerant compressor is a double-acting refrigerant compressor having a piston guided freely on two opposite cylinder portions. The cylinder sections are not movable relative to each other. The piston has an inside through the piston extending through the flow channel. Each cylinder section and the piston have at least one check valve along the flow channel, wherein the flow directions of the check valves are rectified.
- the cylinder sections may be components of a one-piece cylinder or separate components. It is crucial that the cylinder sections are not movable relative to each other and that the piston in the cylinder sections freely, that is without a connection with other components, such. B. piston rods, and is sealingly guided.
- the piston Through the piston is an internal flow channel Nal from the one piston end to the opposite end of the piston completely passed.
- the piston has at least one check valve in the region of the flow channel.
- Each cylinder section also has at least one check valve.
- the flow channel is formed along a straight longitudinal axis, along which the check valves are arranged. The flow directions of the check valves are rectified, that is, when flowing through the piston by a refrigerant in a first flow direction, the check valves are open and flow through the piston in a second, opposite to the first flow direction through the check valves lock.
- the advantage of the refrigerant compressor according to the invention is that a separate bypass line for removing refrigerant from a refrigerant system into a recycling container is not required until pressure equalization.
- the in- nenhold flow channel can easily, z. B. by a bore.
- seals for connecting an external mechanism to the piston through the cylinder are not required. The only seals are to be provided in the area of the check valves and the contact areas between the piston and cylinder sections.
- such a distance is provided between the cylinder sections, that a region of the piston is freely accessible from the outside, to allow access to the piston to drive it without passing seals through the cylinder sections.
- the piston is provided between its two end-side compression surfaces with an auxiliary compression surface which forms an auxiliary volume together with one of the two cylinder sections, which generates a driving force counteracting the return force during a stroke of the piston by a driving force.
- both cylinder sections can be guided as inverse pistons in the piston, wherein the two cylinder sections are immovable relative to each other and only the piston performs a movement.
- the piston can non-contact by two counter-rotating Elektromag- nete, z. B. as a flat armature drive or as Tauchankerantrieb be driven.
- the armature plate advantageously protrudes into the magnetic field generated by the electromagnets through the distance between the two cylinder sections.
- the plunger armature drive the piston can be completely guided as a plunger anchor inside a one-piece cylinder.
- FIG. 7 shows a fourth exemplary embodiment in a first operating state
- 8 shows the fourth embodiment in a second operating state
- Fig. 10 shows a sixth embodiment
- Fig. 12 an eighth embodiment
- Fig. 13 shows a ninth embodiment.
- the compressor system consists of the stepped cylinder 1 in which the piston 7 is guided with the central overflow channel 9 in the axial direction.
- the cylinder is closed by the inlet valve plates 2 and the outlet valve plate 3 in which the inlet valve 10 and the outlet valve 12 are inserted.
- the overflow channel 8 is closed on the outlet side associated with another valve 11.
- the left-hand enlarged-diameter portion of the stepped cylinder 1 constitutes the first cylinder portion 41 and the right-hand reduced diameter portion constitutes the second cylinder portion 42.
- the two cylinder portions 41 and 42 are integrally connected with each other to form the cylinder 1.
- the basic function of the double-acting in-line free-piston compressor is described as follows:
- the piston is brought by a drive not shown here in a linear oscillatory motion. This can be done as a resonance vibration or as a forced vibration.
- the compressor has three characteristic volumes that influence the work of the system and determine the force distribution: the low-pressure working volume 4
- auxiliary volume 5 which helps to control the piston (best with bypass to the left in front of the valve 10, or to the right of the valve 12)
- the medium is displaced in the low-pressure working volume 4. Since the valve 10 closes due to the increase in pressure, the medium is forced into the increasing high pressure working volume 6 via the overflow channel 8 and the overflow valve 11. As a result, a precompression of the medium is achieved, wherein the precompression is approximately determined by the ratio of the cylinder cross-sections of the low-pressure working cylinder 4 to the cross section of the high-pressure working cylinder 6.
- the design has the advantage of providing passive pressure equalization between the inlet and the outlet.
- the bypass conventionally required by the prior art may be eliminated. Due to the construction of the double-acting inline free-piston compressor, the medium can flow directly through the inlet valve 10, the overflow valve 11 and the outlet valve 12. This can be done both as a liquid and as a gaseous fraction.
- Variant 1 The volume is vented to the environment. So the pressure is always
- Variant 2 The volume is gas-tight and comes with a constant admission pressure
- Variant 3 The volume is connected to the inlet pipe, so that the
- Variant 4 The volume is connected to the outlet line, so that the
- a modification of the first embodiment results from the opening of the cylinder in the middle, so that as a second embodiment, a design according to FIGS. 3 and 4, in which the first cylinder portion 41 is spaced from the second cylinder portion 42.
- the compressor with inverse compression chamber consists of the piston 25 with the overflow channel 8, the intermediate valve 11 and the inverse compression chamber 6.
- the piston 25 runs in the cylinder 24, which is closed with the inlet valve plate 2.
- Intake valve plate 2, cylinder 24 and piston 25 form the low-pressure compression volume 4.
- An advantage of this arrangement is the direct mechanical access to the piston while maintaining the inline flow of the medium, so that on the one hand the drive of the piston can be done with a forced operation, for example with a crank mechanism, and on the other hand, the medium directly from the inlet through all the valves through to the outlet can flow.
- both cylinder sections 41 and 42 are guided as inverse pistons in the piston 25.
- the fifth embodiment of FIG. 9 shows a flat armature drive for driving the piston.
- the piston which itself may be made of a material that is not relevant to the drive, is mechanically connected to the armature plate 52 made of magnetically soft iron.
- armature plate 52 made of magnetically soft iron.
- a pot magnet consisting of the iron core 50 or 54 and the electric coil 51 and 53 is arranged.
- By alternating energizing the coils is each generates a magnetic field between the pot magnet and the anchor plate, which puts the anchor in the appropriate movement.
- this can be a slide switch which switches the current lead to the other coil when a predetermined end position is reached.
- a solenoid-spring drive is applied to the piston.
- the operating principle is a spring-mass oscillator, wherein the piston is excited as mass to an oscillating motion.
- the work that the machine is to deliver acts as damping and must be applied as a synchronous excitation by the magnet.
- the principle is very effective for smaller jobs. For a vibration to actually take place, the kinetic or potential energy stored in the spring-mass system must be greater than the work to be delivered.
- a plunger is used as a drive for the piston.
- the coils mutually generate a magnetic flux in the left or in the right area of the plunger coil.
- the anchor is then pulled each time in the appropriate end position.
- it depends on an optimized control of the coil in order to avoid unrestrained striking of the armature.
- the control of the coils is carried out in the same manner as in the flat armature drive.
- the piston 7 is driven via an eccentric guide 61 with a shaft 60 through a conventional crank drive.
- the symmetrically arranged shaft 60 of the rotary drive can be converted via known methods into a positively driven oscillation.
- the method can be used for both normal construction and inverse compression chamber design.
- the advantage here is the use of normal rotary drives and the positive control of the way.
- a rotary drive 71 as in FIG. 13, whose axis of rotation corresponds to the central longitudinal axis of the piston 7, serve with an inner nose 72 in a slide track 73 arranged on the outer peripheral surface of the piston 7 in the form of a " 8 "to engage by rotation of the rotary drive 71, the piston 7 in an oscillating stroke movement.
