Description of the Invention: [Technical Field] The present invention relates to a cold coal for a refrigeration system, and more particularly to a cold coal which is less harmful to the environment than conventional cold coal, and which is provided by the refrigerant Low freezing temperature. More particularly, the invention relates to a cold-war system in which a cold coal system according to the present invention can be used. [Prior Art] A well-known cold beam system includes a cold beam passage in which _ a coal flows. In this freezer channel, several components are provided, such as a reducer, a condenser, an expander, and an evaporator. The cold; the east channel is also I 1 and the 3 s cold coal system is enclosed in the channel. The compressor is replaced by a parallel-connected compressor. This is a general situation. In the cold-rolling system, there are many cold coal stations. For example, the cold rolling system is two in the supermarket. . The refrigeration system as described above, the general function is as follows, the gas cold coal enters the compression H and is contracted by M, and then the cold coal enters the condenser: part: at least condensed, that is, at least partially cold The coal system is in a liquid state when it leaves - Hai... The cold coal is then passed through an expander, for example, to control the flow of cold coal in the system in the form of a expansion grid, and the coal system is expanded', i.e., the pressure of the cold coal is reduced. The cold coal then enters the base: where the liquid cold coal evaporates. Because this is an energy consuming program: the heat system "extracts in the environment" to take a cold, the east phenomenon is generated at the position of the evaporator. Take the 'gas cold coal' - and then enter the compressor. 6048-8921~PF/Ahddub 6 200817644 In the cold bead system, a conventional refrigerant such as R404a or R5G7, as described above, can be used. The disadvantage of such a cold coal is that it can be used in a home or supermarket. In the cold (four) system, that is, it is suitable for the cold of material I about 5 degrees C; the cold coal of the east temperature or the cold bead of the temperature suitable for maintaining the temperature of about ... degrees c. In some applications, a lower cold beam temperature is required. This example is the status of a medical application, such as a library of various vaccines, serum or tissue samples: these products must generally be exposed to temperatures below _7..., and more often, this order of magnitude cold; For food processing, for example, in the process of transportation, the stored products do not produce higher than the above-mentioned special temperature 'even the product moves from the - transport device to the other one. In order to obtain a lower freezing temperature, various methods are used. One method is called tandem cooling, and the east system 'two or more of the independent cold image systems are used, and the mth system cools the next cold. The appropriate temperature of the cold coal, etc., # select the cold coal by an appropriate method, - an effective low cold temperature system can finally be obtained, the disadvantage of this method is the need to use two or more compressors At least one is to be used in each step of this series connection, so the system is very energy intensive. Another method is a so-called mixed gas refrigeration system in which a system of used, washed cold coal is mixed with various gases having different boiling points, which is used in the gas - undergoing a phase transition, which is not from The energy consumed in the environment is to send energy to the environment, depending on the type of phase transition, so when the gas has the highest boiling point to evaporate the energy loss, at 6〇48-8921-PF; Ahddub 200817644 Luhai strip is used in Cold; East.com surname# ship sorrow, quasi-holding milk, preferably until it begins to condense, this can happen in the heat exchanger, the helmet τ in order to pay for the required two hydrocarbons

The disadvantage of the body of cold coal is that HFX gas is not conducive to the environment' and the cold coal is not good from an environmental point of view. SUMMARY OF THE INVENTION The object of the present invention is to provide _; human® μ 仏々 仏々 coal for providing a low freezing temperature and having an environmentally superior advantage over conventional cold coal. Cold coal system can provide low freezing temperatures. Another object of the invention is to provide one degree 'without requiring multiple compressors. Still another object of the present invention is to provide a cold rolling system which provides a low cold beam temperature & which is advantageous over the environment compared to conventional cold materials. According to a first aspect of the invention, the above and other objects are achieved by providing a cold coal for use in a refrigeration system comprising a mixed gas having three different hydrocarbons (hydr〇carb〇n And comprising: isobutane = (iS〇bUtane; C4H1.), ethylene (ethene; C2H4) and a: (methane; CH4), wherein the mixed gas comprises at least 7% by weight of isobutane. The inventors of the present invention have surprisingly discovered that a mixed gas contains at least three different hydrocarbons, which can be used as a cold coal for providing a very low freezing temperature at a freezing station, and 4 is a refrigeration system that does not require a series connection. In this way, only one compressor is needed, which saves energy compared to the conventional series cold beam system. Moreover, S is the cold coal system of the f. * or 604 8-8 921-PF; Ahddub 8 200817644 A large number of cigarettes obtain a 'hydrogen fluoride system in the mixed gas. It is not necessary. According to the above, the cold coal of the present invention is better than the conventional cold coal. Therefore, the first shape of the cold coal according to the present invention provides a very low freezing temperature in a manner that is better for the environment, in part because it is comparable to the conventional tandem system, which is due to the fact that hydrogen is not required in cold coal. Fluoride beans a are very advantageous. The mixed gas may further comprise a plurality of constituents, such as additional flues, for example, one or a plurality of hydrocarbons or other kinds of gases or liquids in an impure form. The mixed gas contains isobutane (d.), ethene (C2H4), and methane (CH4). The inventors of the present invention have found that the mixed gas is particularly suitable for providing a very low cold coal. The freezing temperature does not require a series of freezing systems. Because isobutane has a relatively high boiling point (about -16 ° C) at atmospheric pressure's when ethylene and methyl sulphide have relatively low boiling points at atmospheric pressure (about -1 〇 5 degrees c and -18 分别, respectively). Degree c). The isobutyl burned vapor provides cold coal for use in the mixed gas in the presence of ethylene and methylation, whereby the isobutylate is used to aid in the condensation of the ethylene and the formazan. More specifically, the boiling point of the '$ethylene and f-fired' is sufficiently different when it is produced to provide a similar contribution to the isobutylate. Between 70% and 80%, for example, the main part of the mixed gas is formed in the Dingyuan, and the hydrocarbons as described above are selected in a manner that provides a desired degree of cold coal in the mixed gas, the mixed gas Containing at least 7 〇% by weight of 3:10% isobutane, for example between 70% and 75%, so the amount of isobutane supplied by isobutane to the source of refrigeration should be chosen by a relatively large percentage of 6048-8921 - PF/Ahddub 9 200817644 This is advantageous in some applications for the high level of isobutane 'other hydrocarbons' refrigeration sources that can be obtained. One of the hydrocarbons is equal to -40 degrees C, or equal to -16 degrees C. For example, greater than or equal to -25 degrees C, such as greater than or equal to or additionally, at least one of the hydrocarbons may have a boiling point at atmospheric pressure, which is less than or equal to the degree of c, for example Less than or equal to -120 degrees C' is, for example, less than or equal to _15 degrees c. One of the hydrocarbons may have a temperature of _12 〇 (: to _1 c degrees c at atmospheric pressure, and the other of the hydrocarbons may have a temperature of less than or equal to _15 In this case, a hydrocarbon having a higher boiling point may be used as the colder having a lower boiling point. In a preferred embodiment of the present invention, one of the hydrocarbons has One of the boiling temperatures at atmospheric pressure is greater than or equal to -40 degrees C, and two of the hydrocarbons have a boiling point temperature at atmospheric pressure less than or equal to -1 〇〇 c, that is, one of the hydrocarbons is relatively high. The boiling point and two of the hydrocarbons have a relatively low boiling point, whereby, upon evaporation, the hydrocarbon having a high boiling point provides a source of refrigeration to the other two such as the above-mentioned cigarettes. Alternatively or additionally, at least one of the hydrocarbons One may have a dry circumference of -45 degrees C to -130 degrees C in a gas-liquid region, and at least one pressure in a pressure range of 〇.2bar to 35 bar, which has the advantage that at least one hydrocarbon is under normal operating conditions. In a gas-liquid region, whereby the hydrocarbon can provide cold coal to others in the above manner He is a hydrocarbon. The mixed gas may contain a weight percentage of between 1% and 69% of B 10 6048-8921-PF/Ahddub 200817644, for example between 1% and 50%, for example at 5% and Between 40%, for example between 15% and 30%, for example between 20% and 25%. Alternatively or additionally, the mixed gas may comprise between 1% and 69% by weight. Methane, for example between 1% and 50%, for example between 2% and 30%, for example between 3% and 20%, for example between 5% and 10%. In a preferred embodiment, the mixed gas comprises about 71% by weight of isobutane, about 24% by weight of ethylene, and about 5% by weight of methane, and the mixed gas can be used to obtain a freezing temperature of 79 degrees C or less. For example, it is -85 degrees C or less. As described above, such a low freezing temperature does not require a cascade refrigeration system and does not require the addition of ruthenium fluoride to the cold coal. According to the second aspect of the present invention, Other objects are accomplished by providing a refrigeration system comprising: a compressor; a condenser; a heat exchanger; The expander; wherein the compressor 'the condenser of the sakisaki - the government mouth, the 〆 transition state, the expander and the μ 瘵 态 彼此 彼此 彼此 彼此 彼此 彼此 彼此 彼此 彼此 彼此 彼此 , , , , , , , , , , , , The above-mentioned first shape energy, f |7 terminal, and charging system. The m-phase cold coal is filled in the cold-conducting channel and needs attention to 6048-8921-PF; Ahddub related art can easily understand any in this 11 Further description of the combination of the first aspect of the invention may be combined with the second aspect of the invention, and vice versa. The second aspect of the present invention provides a refrigeration system suitable for use in the application of the invention. Cold coal, according to the second aspect of the present invention, is suitable for providing low freezing temperatures at low energy consumption without requiring special requirements for the cold; in the components of the East system, based on durability and Rugged and so on. The functions of the compressor, condenser, expander and evaporator are as described above. The cold 4 system further includes a heat exchanger that preferably operates in the following manner 'The heat exchanger is passed through cold coal flowing in opposite directions, a more detailed description will be given below Description. The chilled passage forms a closed line as previously described. Preferably, the chilled passage is closed at least substantially in a sealed manner. The refrigeration system can be a refrigerator. According to this embodiment, the evaporator provides cold coal to - cold; the desired product can be stored. Since the cold temperature system provided is very low as described above, the storage temperature of the cold bundle in the crucible is correspondingly low, so the product is stored at a very low temperature, that is, it is suitable for storing medicines, for example Store a variety of vaccine, serum or tissue samples. At the same time, the refrigerator operates in a manner that is very similar to that of a general household refrigerator, thereby being installed and driven very easily and simply. Alternatively, the shai refrigeration system can be a cooling device for a central processor. 'The central processor that is placed in the computer device will often need to be cooled. This cooling can be cooled by the second direction according to the present invention. Provided by the system. In this case, the evaporator should be placed in close proximity, preferably in thermal transfer contact with the 6048-892l-PF; Ahddub 200817644 central heat generating portion of the central processor. [Embodiment] The embodiments of the present invention are described in detail below, and are illustrated by the accompanying drawings. The following examples do not limit the scope of the invention. 1 is a schematic view of a refrigeration system 1 ,, having a compressor 丨i, a first condenser 12, a filter dryer 13, a second condenser 14, a heat exchanger 15, an expander 16, an evaporator 17, and a battery. 18 is connected in such a way as to form a closed line. In the closed circuit, the cold coal system according to the first aspect of the present invention is allowed to flow in, and the function of the refrigeration system 1 将会 will refer to the cold coal having isobutane, ethylene and methane in the =-comprising-mixed gas. To illustrate. The gaseous cold coal enters the compressor U and is compressed. The compressed cold coal then enters the first condenser 12, wherein the cold coal is at least partially condensed, and then the cold coal enters the filter dryer 13, so that moisture will The unabsorbed material in the system is collected and the cold coal enters the second condenser 14 to allow the cold coal to undergo further condensation. Since the second condenser 14 is disposed, the cold coal enters the heat exchanger 15 and the heat is converted to the separation pipe in the opposite direction to the cold coal. This portion will be described more in the following, and the cold coal is converted from heat. The 15 passes through the expander and the pressure of the cold coal is reduced, and the expanded cold coal continues to vaporize into the evaporator, thereby providing a source of cold beads, such as a cold bead. After the evaporated cold coal enters the heat exchanger 15, the cold coal enters the battery 18, and the battery 18 operates as a cold coal buffer. This arrangement compensates for the large flow of cold coal 6048-8921-PF; Ahddub 13 200817644 The dynamic movement is the result of changes in the installation of cold coal. Finally, the cold coal enters the compressor 11. In the heat exchanger 15, the following situation occurs, in which the cold coal enters the heat exchanger J 5 from the second cold-rotator 14, and the isobutane undergoes a phase transition from a liquid to an air-off. That is, A, wins the energy from the environment by the isobutane in the '% 疋 cold coal, provides the chilled coal to the cold coal of ethylene and methene. At a certain point, ethylene will reach the point of the Buddha, and the box will be converted into a liquid phase. In the case of further freezing of the field 4, the condensing will start similarly, and the cold 70 17 ^ 7 will flow in the opposite direction, that is, the cold coal passing from the 茱^ 17 into the heat exchanger 15,

When the cold coal has completely entered the liquid state, the 疋 meaning is in the liquid phase and the two (four) boundaries of the song (four) from point 2 to point 3, the cold coal system passes through the expander]6, from the first _ Chu understand the result is The temperature drops (because of the pressure & / month;) the field energy system dimension 6048-8921~pp/Ahddub 14 200817644 held at - fixed value, more widely, this two-phase area was once again entered. From the black " to the point 4', the cold coal system is subjected to evaporation by steaming, as can be seen from Fig. 2, the cold (2) 1 β Chu knows that the temperature is at a certain value because the phase transition occurs. θ, maintenance of the know-how 4 旎 system is increased, that is, energy can be consumed from the environment, thereby providing a source of refrigeration.
