Description

Process and equipment for enhanced efficiency of compressors and refrigerators. This is a descriptive circumstantial report on the invention. It refers to this invention, which is a set of moveable mechanisms and immoveable parts, which are inserted in refrigeration compressors, as well as inserted in the refrigeration preparation process (and/or air conditioning appliances, drinking fountains, etc. . . ) it greatly improves the performance of these kinds of equipment, decreases electrical consumption, as well as; making cooling faster (i.e. achieve low temperatures), also increasing the useful life of these kinds of equipment, decreases maintenance costs (refrigeration repair technicians, it is a known fact; for example, refrigeration appliances when they are turned off for long periods of time, create rust inside, in the compressor, this problem will be done away with by using our invention, the subject of this patent request), it also makes it possible to manufacture compressors with decreased noise (therefore it runs more silently), smaller in size, lighter in weight, and less quantities of raw materials, among other benefits derived from using our invention, herein introduced and described, which is all part of this invention patent request.
In the accompanying drawings and which is an integral part of this report, FIG. 1 (FIG. 1), displays a normal side view of the compressor, commonly used for refrigeration, whereas number 5 displays the compressor base (or compressor foot), number 6 displays the compressor housing, and number 7 displays the compressor cover. Still in FIG. 1, tubes number 25, number 26, and number 27 display the refrigerant gas flow tubing, whereas number 25 is named the “process tube” (or in other words, where refrigeration gas flows in and out at the time refrigerant gas is prepared for refrigerating). Number 26 is the tube where the high-pressure tube welding is (also known as the “exhaust tube”), number 27 displays the suction tube (or the gas-return tube, from the refrigerator to the compressor, whereas “each new cycle” begins). Number 8 is a tube which is not employed in current refrigeration technology, however, we are innovating this, and this is one of our patent claims for this invention.
In FIG. 1, the tube indicated by n# 8 is part of the compressor (as well as the other three n # 25, #26 en n#27). Note that the tube n # 8 is installed on the lower side of the compressor, where the lower part of the pipe almost touches the reservoir oil.
Thus, on #3 indicates the oil level in the reservoir (when the compressor is at rest), on #4 indicates that reservoir. Scientifically, we have that the refrigerant gas has low density (much lower than the atmospheric air). The operator must prepare for the refrigerator, will be instructed to perform a different process of entering gas. For now, before you put gas in the system, it is only a vacuum by connecting a vacuum pump to the process pipe (see paragraph # 25 of drawing FIG. 1), and “supposedly”, or mistaken, thinking so that it is removing moisture and air from within the system (inside the compressor and the pipes). Our process is proposed (and claimed to) begin the installation of gas.
Making up a decontamination process prior to removal of “all air” still existing in-house system. Thus, the operation of placing gas compressors in refrigerators and in gas cylinders (whether coolant gases or fuel gas as in cooking gas cylinder, gas cylinder or soft drinks for resale at retail) will henceforth be performed using our technology in the previous withdrawal of all the air contained inside the container (it being understood as a container: the screw, cylinder, hermetic compressor, piping, refrigerator, etc. . . . ). The specific process of putting gas in the refrigerator (air concionado and related devices, will follow basically the following sequential steps:
1) have the prior process of vacuum (to remove internal moisture).
2) put a little gas in the system at a pressure of about ¼ or the normal working pressure for this pipe using the normal process (see paragraph # 25 of FIG. 1). The gas for this step can be the same initial working gas, or can be any inert gas (also called rare gases, for example, argon, xenon, krypton, etc. . . . ).
3) Wait about a half-time hours (ie leave the “rest system”) for heavier than air will settle on the bottom, above oil.
4) Using “clean pipe”, see n. 8 # en #2, removing the air that is under pressure deep inside the system, since opening the “clean pipe”, will come under pressure a little gas soda and all the atmospheric air, which is in the lower part of the system (because the air atmosphere is heavier than the refrigerant gas). However, the opening operation of the tube-to-clean, be quick, or controlled, not to allow the pressure falls to zero. That is, it is necessary to close the tube-to-clean quickly, so that it is a residual pressure (however small) within the system. Well, cannot return air into the system.
5) Seal (kneading and welding) the output of “clean pipe”.
6) complete gas charge. Important Note: Before operating with refrigerant, it is necessary to remove all existing in the atmospheric air hoses, pressure gauges (manifold), etc . . . Interestingly and unfortunately, this is not normally done by manufacturers and repair shops for refrigerators. The term described above as “clean pipe”, is a term created by us (for the occasion and necessity of this patent). Thus, this “clean pipe” specific, there is no refrigeration compressors in the current state of the art. Thus, for continuation and regularization of the procedures above to fix the exact amount of gas that must enter the system, you can use as alternatives, for example:
a) measuring the weight and volume of the amount of air left the system by “clean pipe” and compensate for this weight and volume, weight and volume of refrigerant to be introduced. Or,
b) measure the system pressure by adjusting it on the low side and high pressure. Or,
c) making up the various procedures of adjustment amount of gas inside the cooling system. The new process for high efficiency cooling, sometimes described putting gas in the sealed refrigeration systems free from any contamination, caters for all types of gas, for example: -A R134, R600, etc . . . So, you get better results for less miscible (ie the less miscible) is the refrigerant used with atmospheric air. To escape the need to use our technology-of-pipe decontamination, manufacturers of refrigerators and/or repair shops will try to use a device not advisable, not to add the tube-to-clean, but only to create a controllable output of the gas in the tube-of-process (see FIG. 1, n # 25, existing compressors in the current state-of-15-technique), this is discouraged because: since the air is heavier than gas cooling and/or noble gases then the atmospheric air will not leave and will remain in the background the container. However, this patent also claims process by removing the air tube process (allowing air flow mixed with “a little” gas coolant, maintaining residual pressure within the system before completing the load of gas).
In FIG. A clean tube, the part that becomes apparent, is indicated by the numbers 1 and 2, where n #1 indicates the point where the tube touches the wall of the compressor en #2 indicates the body of the tube-to-clean. However, the total length of the tube should be up near the center of the compressor. For, along the inner vertical walls of the compressor may contain refrigerant. The tube-to-decontamination shown in FIG. 1, is horizontal and enters the lower lateral wall of the compressor. However, also this pipe-to-decontamination could go vertically from the bottom center of the compressor and bending out horizontally.
It should also be noted that the tube-to-decontamination is straight, unlike the tubes, or existing, which are indicated by the numbers 25, 26 and 27 and are curved. This patent claims straight pipes (not curved, for all tubes from the compressor), this to avoid the five operations of welding, the weld drain liquid into the compressor, or the inside of the tube (for example, in welding oxy-acetylene, we use a cleaning product with the material flux and this cleaning product flows under the influence of fire, or heat weld). The cleaner oxy-acetylene welding is a contaminant of the refrigerant gas, so should be banned from the internal environment of the compressor (mainly welding in workshops cooling, it is a little product that will always stay inside but their quantity should be reduced to the lowest level).
In FIG. 2, shown is another important development, it is shown a set of pieces on a normal compressor # 54 is a coil (or coils) n of the electric motor is the stator 55 #, 50 # n is the block (or base) that adds parts, n # is the shirt 51 (or cylinder) where the piston works, note that this cylinder, in our invention is the double (or symmetrical) given by n #51 (right) en #62 (left side). The n # n #52 e indicate 63 and valve plate assembly for compression, n # 53 en #65 indicate lids (or heads), which are held by screws to the respective cylinder.
Still in FIG. 2 on #57 indicates a central axis with an eccentric, which acts as a crankshaft, which moves the piston (two pistons of a symmetric n is indicated by #66 (see FIG. 3). N #60 indicates a bearing, the other bearing is indicated by n # 58 that rotates around the axis 57, are two bearings (one over the other) where each of its respective piston moves, each of the bearing is connected to the rod, by passing a pin fastener, or by an external clamp. Paragraph #61 is a rod (we two, of course), which connects the piston to the bearing 56 indicates a hollow, inside the block, so the compressed gas pressure in the compression chamber before go tubing, pass through the hollow (which serves as auxiliary chamber compression and decompression, improving slightly the process of refrigeration). Each piston chamber (symmetrical) discharges the compressed gas to assist their respective camera (or hollow). Paragraph # 59 indicates a thin washer (eg. With a thickness of 0.1 mm, 0.2 mm or 0.3 mm) hard plastic or metal, placed between the two bearings. Whose function is to relieve the mechanical moment, which tends to create counter force to the rotation of the bearing onto the shaft. In FIG. 4 (page 3 of the sheet of drawings) was added to the tubes passing gas. Paragraph # 80 is an outlet pipe of a gas chamber and paragraph # 81 is another correspondent. The tube 81 out of a compression chamber and enter the part ## 83, to where the gas is also out of another camera, so both gases exit through the tube n # 80, where the compressed gas leaves the compressor and returns to the inlet (or suction) indicated by n # 67 en # 64, the drawing FIG. 2.
FIG. 5 is a top view of the assembly shown in FIG. 4 (at the top of the drawing sheet number 3). In the fourth sheet of drawings shows the set described above, now sealed inside the body, parts of whose numbers match the description given earlier.
FIG. 6 shows the body is sealed open (ie without the lid, which is welded to the body) all mounted on block, also called “base”, is supported on four springs, fitted into brackets welded to the inner wall of the airtight body . These four springs are mounted to form a rectangle, whose vertices are in brackets.
FIG. 7 shows the set with its sealed lid. Paragraph #85 indicates the junction of two pipes of gas under pressure (indicated by 80 and 81, see FIG. 6, and FIG. 4 on page 3), leaving the compression chamber. Notice that now is shown an alternative/different output tube 81 now is not going to play (plug, or “lung”) indicated by 83, but I came straight to the discharge tube (n #86). Thus, this alternative both tubes coming out of their chambers will meet in the discharge pipe. The present patent claims both forms of output pressure tubes.
In FIG. 6 (page 4) is not shown, the tube-cleaning described in the opening pages (see FIG. 1 n #1 en #2 respectively base and body of the tube-to-clean). But merely shows how the compressor is the current state of the technique (with its tubes process ##88 of 86 discharge and suction 87).
FIG. 7 shows the shape of the lid, with two “assess” to better accommodate our symmetric system/invention, two symmetrical compression chambers.
In the fifth sheet of drawings, it presents a view-to-face (see FIG. 8) and top-of-view (see FIG. 9) overlapping of the two bearings (in FIG. 3, page 2, this bearing is indicated by paragraph #60), here it is presented separately bearing mounted on the shaft for better understanding. Note that the holes indicated by n # 95 #96 en option that are fit to the rod by pins (optionally power would use external clamp), serve as reference that are in the same horizontal line, even though the bearings are overlapping (so it has two symmetrical pistons, aligned at the same vertical height and the same horizontal alignment).
The number # 97 indicates a base on the shaft, which supports the bearings (which improves durability, but may optionally be dispensed with this base).
