[Prior Art] Over the past few decades, the refrigeration industry has been looking for alternative refrigerants to replace the phase-out of ozone-depleting chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) due to the Montreal Protocol. The solution for most refrigerant manufacturers' is commercialized hydrofluorocarbon (HFC) refrigerant. Among the new HFC refrigerants, HFC_134a is currently the most widely used. This type of refrigerant does not have an ozone depletion potential and is therefore not affected by the Montreal Protocol's regulation that specific refrigerants must be phased out. However, further environmental regulations may eventually result in the global decommissioning of certain HFC refrigerants. At present, the automotive industry is also constrained by the global warming potential regulations for refrigerants used in automotive air conditioners. Therefore, there is an urgent need for new refrigerants that provide a low global warming potential for the automotive air conditioning market. If these specifications are to be expanded in the future, for example, for stationary air conditioning and refrigeration systems, there will be greater refrigerant demand in all aspects of the refrigeration and air conditioning industry. The refrigerants currently proposed to replace HFC-134a include HFC-I52a, pure hydrocarbons such as propane or butane, or "natural" refrigerants such as C02. Many proposed alternatives are toxic, flammable and/or have low energy with 201219349 effectiveness. Therefore, new alternative refrigerants are currently being sought. Alternatives to HFC, CFC and HCFC refrigerants, such as CFC-11, HCFC-22, HCFC-123, HFC-245fa, R404A, R407C and R410A, have also been proposed.

[Embodiment] Some terms are defined or clarified before the details of the following embodiments are presented. Definitions As used herein, the term heat transfer composition means a composition for carrying a heat sink from a heat source. A heat source is defined as any space, location, object, or body from which to transfer, move, or remove heat. Examples of heat sources include spaces that require freezing or cooling (open or closed), such as freezers and freezers in supermarkets, building spaces requiring air conditioning, industrial water freezers, or in-vehicle passenger compartments that require air conditioning. In certain embodiments, the heat transfer composition may be in a constant state or phase of molecular aggregation (i.e., not evaporated or condensed) throughout the transfer. In other embodiments, the evaporative cooling process may also utilize a heat transfer composition. 7 201219349 A heat sink is defined as any space, location, object or body that can absorb heat. The condenser of the cooling water passing through the vapor compression refrigeration system is an example of the heat sink. A heat transfer system is a system (or apparatus) for producing a heating or cold effect in a particular space. The heat transfer system can be a mobile system or a stationary system. Examples of heat transfer systems include, but are not limited to, air conditioners, freezers, freezers, heat pumps, water freezers, immersion chillers, direct expansion chillers, walk-in chillers, supermarket systems, heat pumps, mobile chillers , mobile air conditioning units and combinations thereof. As used herein, a mobile heat transfer system refers to any type of cold bead, air wrap, or heating device incorporated into a transport device for rail, rail, and air. In addition, mobile cold; east or air conditioner units are included in any mobile vehicle and are known as noodles

Those devices. , 屮相_ A This combined transportation system includes "container" (combined sea/land freighter) with beta "road/railway transporter". "swap bodies" (joint fixed Hf fixed heat transfer system is During operation, it can be connected to the building, or it can be combined with or connected to various types of merchandisers. The separate devices outside the fixed temples, such as refreshing drinks, are not limited to chillers, and can be used for stationary air conditioners. And heat pump (including system, and including window: warm f, residential, commercial or industrial space and installed in the external value of the tube, (four), packaging terminal, cold ball fixed refrigeration application, killing connection For example, the roof system).

In certain embodiments, the disclosed compositions can be used in supermarket refrigeration systems. Fixed system A second loop system using a first refrigerant and a second heat transfer fluid. The term refrigeration capacity (also known as cooling capacity) is used to define the enthalpy change of the refrigerant in the evaporator for each cycle of refrigerant. Or the heat (volume) removed by the refrigerant in the evaporator for the refrigerant vapor leaving the evaporator per unit volume. The cold capacity is used to measure the ability of the refrigerant or heat transfer composition to cool. Therefore, the ability High, the more cooling per unit mass or volume of refrigerant passing through the evaporator. The cooling rate means the heat removed by the refrigerant in the evaporator per unit time. The coefficient of performance (COP) is the heat removed. The input of the helium source required to operate the cycle. The higher the COP, the higher the energy efficiency. The COP is directly related to the energy efficiency ratio (EER), which refers to the efficiency of the refrigeration or air conditioning equipment in a specific set of internal and external temperatures. The supercooling is the decrease in the temperature of the liquid below the saturation point of the liquid at a certain pressure. The saturation point is the temperature at which the vapor composition completely condenses into a liquid (also known as the bubble point). The constant pressure is cooled to a lower temperature liquid. The net freezing capacity can be increased by cooling the liquid to below the saturation temperature. The supercooling thus improves the refrigeration capacity and monthly efficiency of a system. The subcooling amount is lower than the saturation temperature. The amount of cooling (in degrees) or a liquid composition is cooled to below its saturation temperature. Overheating is a term that defines how much heating a vapor composition exceeds its saturated vapor temperature (saturated vapor temperature is if the composition is cooled) The temperature at which the first drop of liquid is formed, also known as the "dew point". 201219349 Temperature glide (sometimes simply called "slip") is a refrigerant in one of the components of a refrigerant system. The absolute difference between the start and end temperatures of the phase change process, and excluding any supercooling or superheating. This term can be used to describe the condensation or evaporation of a near azeotropic or non-azeotropic composition. By azeotrope composition is meant a constant boiling mixture of two or more substances which behaves as a single substance, a characterized azeotropic composition, or a vapor produced by partial evaporation or distillation of the liquid. The same composition of the liquid (the vapor is evaporated or distilled from the liquid), that is, the composition does not change upon distillation/reflow. The azeotrope composition is characterized by having azeotropic properties' because they exhibit a highest or lowest boiling point compared to a non-azeotropic mixture of the same compound. The azeotrope group will not be fractionated in the operating refrigeration or air conditioning system. The above phenomenon Γ = low system heat transfer and efficiency. In addition, fractionation does not occur when the azeotrope is leaked from a cold or = system. As used herein; or after two parts by weight of the composition is removed (for example, in the steaming " a1)', the vapor between the original composition and the composition after removal of 50 weight percent is not available. The measured difference is defined as (4). Two 3 = 5 species (generally referred to as "near azeotrope compositions") are mixtures of a certain mass that are similar to a single component pure azeotrope: a constant temperature boiling of the secondary mass 4 . - a characteristic type of vapor is partially formed by vaporization or steaming of the body, and the composition is changed; the liquid trays of Luo Gu have substantially the same shape - the composition of the money compound does not change in the real f composition" Another way of characterizing azeotrope-like composition 10 201219349 is that the bubble point vapor pressure of the composition is substantially the same as the dew point vapor pressure at a certain temperature. Here, 'if 50 weight percent composition After the material is removed (for example, by evaporation or boiling), the vapor pressure difference between the original composition and the composition remaining after removing 50% by weight of the original composition is less than 10%, then the composition That is, defined as an azeotrope-like. A non-azeotropic composition is a mixture of two or more substances that have a significant temperature change during boiling at a given pressure. A way of characterizing a non-common composition is from a liquid The vapor produced by partial evaporation or distillation has a substantially different composition from the vaporized or distilled liquid, in other words, the mixture is hot strip/back in the event of a substantial composition change; iW. The manner in which the non-common composition is characterized is that the bubble vapor pressure of the composition is substantially different from the dew point vapor pressure at a particular temperature. In this context, a composition, for example, by bursting or removing it After 50 weight percent, the difference in vapor pressure between the original composition and the composition after removal of 5 weight percent is greater than about 1%, the composition is non-azeotropic. 'As used herein, the term " "Lubricant" means any material m added to the -component or -compressor (and in contact with any heat transfer composition used in any heat transfer system) to provide the compressor lubrication effect to help avoid component jamming. As used herein, a compatibilizing agent is a compound that improves the solubility of hydrofluorocarbons or listeners in the heat-transmitting-slip agent of the compositions disclosed herein. In some embodiments, the compatibilizing agent returns the oil return (four) to the ability of Long Cheng. In certain embodiments, the compatibilizer improves the heat transfer properties of the composition. In certain embodiments, the set of 201219349 strains is used with a system of lubricant to reduce the viscosity of the oil-rich phase. : 'As used herein, oil return means that a heat transfer composition carries a lubricant through a heat transfer system and brings the lubricant back to the compressor. That is, in use, it is not unusual for the heat transfer composition to carry portions of the compressor lubricant away from the compressor and into other portions of the system. In such systems, if the lubricant fails to return to the compressor, the compressor will eventually fail due to lack of lubrication. As used herein, an "ultraviolet" dye is defined as a uv fluorescent or filled composition that absorbs light in the ultraviolet region of the electromagnetic spectrum or in the near ultraviolet region. The UV fluorescent dye is illuminated under a uv light. The resulting fluorescence can be measured by a debt that emits at least some radiation having a wavelength in the range of 10 nm to about 775 nm. The Global Warming Potential (GWP) is an index that is one kilogram of carbon dioxide. Emissions are used to assess the relative global warming contribution of atmospheric emissions of one kilogram of specific greenhouse gases. The effect of retention time of a particular gas in the atmosphere can be understood by calculating GWP' over time. Usually based on GWP over a hundred years For mixtures, the weighted average can be calculated based on the individual GWP of each component. Ozone Depletion Potential (ODP) is a quantitative representation of ozone depletion caused by a substance. ODP is the effect of a chemical on ozone and the same quality. The ratio of the effect of CFC-11 (fluorotrichloromethane). Therefore, the 0DP of cFC-H is defined as. Other CFCs and HCFCs have ODPs ranging from 0.01 to 1.0. HFCs are zero ODP. Term means the ability of a composition to burn and/or spread flames. For refrigerants and other heat transfer compositions, the lower flammability limit 201219349 ("LFL") is the lowest concentration of heat transfer composition in the air.

ASTM (American Society for Testing and Materials) E681 continuation of the flame through a homogeneous mixture of air and composition under test conditions, the upper limit of flammability ("UFL") is the highest concentration of heat transfer composition in the air, which can be used in ASTM The E681 condition continues the flame through a homogeneous mixture of air and composition.

Freezer Apparatus In one embodiment, an air conditioning or freezing apparatus comprising a composition comprising cis-HFO-1336mzz and HFE-236eaEbg is provided. Such a device may be a closed loop heat transfer system, such as that disclosed in U.S. Patent Publication No. US 2008/0314073, the disclosure of which is incorporated herein by reference. In one embodiment, the air conditioning or freezer comprising a composition comprising cis-HFO-1336mzz and HFE-236eaEbg is a freezer. The colder is a type of air conditioning/cold beam device. This disclosure relates to a vapor compression freezer. The vapor compression freezer can be an immersion evaporator freezer, an embodiment of which is shown, for example. The chiller can also be a direct expansion chiller, an embodiment of which is shown in Figure 2. Immersed evaporative frozen and direct expansion chillers can be air-cooled or water-cooled. In embodiments where the community is water-cooled, such chillers are typically spliced to the cooling tower to remove heat from the system. In the embodiment where the cold III is an air-cooled crucible, the freezer is equipped with a condenser coil and a fan of a refrigerant-to-air finned_tube, and is discharged from the hot pack system. Air-cooled cold scrubber systems are generally less costly than water-cooled cutters that include the same cold materials and cores. Due to its more condensing temperatures, many operations such as 201219349 with dehumidified air are given to large commercial buildings, including hotels, office buildings, hospitals, universities and the like. In another embodiment, the freezer, most likely an air-cooled direct expansion chiller, has been found to have additional utility in naval submarines and surface vessels. To illustrate how the freezer operates, please refer to the schema. The water-cooled immersion evaporator is shown in Figure 1. In this freezer, a first heat transfer medium, a warm fluid comprising water, and in some embodiments an additive such as a glycol such as ethylene glycol or propylene glycol is comprised of a cooling system (eg, a building cooling system) Entering the cold beamer, as entered at arrow 3, passes through the coil 9 of the evaporator 6, which has an inlet and an outlet. The warm first heat transfer medium is delivered to the evaporator where it is cooled by a liquid refrigerant which is shown in the lower portion of the evaporator. The liquid refrigerant evaporates at a lower temperature than the warm first heat transfer medium flowing through the coil 9. The cooled first heat transfer medium is again circulated into the building cooling system via the return portion of the coil 9 as indicated by arrow 4. As shown in the lower portion of the evaporator 6 of Figure 1, the liquid refrigerant evaporates and enters the compressor 7, which increases the pressure and temperature of the refrigerant vapor. The compressor compresses the vapor so that when it leaves the evaporator, it can condense in a condenser 5 at a pressure and temperature higher than the pressure and temperature of the refrigerant vapor. The second heat transfer medium (liquid in the case of a water-cooled freezer) enters the condenser from the cooling tower at arrow 1 in Figure 1 via coil 10 in condenser 5. The second heat transfer medium is warmed during the process and returned to the cooling tower or environment via the return loop of the coil 10 and arrow 2. This second heat transfer medium cools the vapor in the condenser and condenses the vapor into a liquid refrigerant, so that there is a liquid refrigerant in the lower portion of the condenser, as shown in FIG. The condensed liquid refrigerant in the condenser flows back to the evaporator via the expansion device 8, and the expansion 201219349 can be an orifice, capillary or expansion valve. The expansion device 8 reduces the pressure of the liquid refrigerant in the liquid and converts the (10) refrigerant portion into steam. That is, the liquid refrigerant has a pressure difference between the condenser and the evaporator of six seconds, and the refrigerant is cooled, that is, evaporated. The pressure τ causes the liquid refrigerant to reach the saturation temperature, and both the liquid refrigerant and the refrigerant vapor are stored in the evaporator. It should be noted that for a single component refrigerant composition, the composition of the vapor refrigerant in the evaporation crucible is the same as the composition of the liquid in the evaporator. In this case, the evaporation will be carried out at a constant temperature, and if the refrigerant blend (or mixture) is used, the liquid refrigerant and the refrigerant vapor in the stripper (or condenser) may be as described in the present invention. Has a different composition. This situation can lead to inefficiencies in the system and difficulties in the use of the device, so it is desirable to use a one-component refrigerant. A total of j or azeotrope-like composition can basically act as a single, and knife-cooling medium in a freezer, so the liquid composition and the vapor composition are substantially the same to reduce the use of non-azeotropic or abundance The effect caused by the object is not good. Freezers with a cooling capacity of more than 700 kW typically use an immersion evaporator in which the refrigerant in the evaporator and condenser surrounds the coil or other heat, medium conduit (ie, the refrigerant is on the shell side). Immersion evaporators require a relatively high amount of refrigerant, but achieve nearer temperatures and higher efficiencies. A chiller having a cooling capacity of less than 700 kW is generally used with an evaporator that has a refrigerant flowing into the tubes and a heat transfer medium (in the evaporator and condenser) that surrounds the tubes, that is, a heat transfer medium. On the side of the shell. This type of freezer is called a direct expansion (DX) freezer. 36 201219349 Figure 2 illustrates one embodiment of a water-cooled direct expansion chiller. In the freezer shown in Figure 2, a first liquid heat transfer medium (which is a warm liquid such as warm water) enters the evaporator 6' at the inlet 14. The liquid refrigerant (having a small amount of refrigerant vapor) mostly enters the coil 9' in the evaporator at the arrow 3' and evaporates into a vapor. As a result, the first liquid heat transfer medium is cooled in the evaporator, and the cooled first liquid heat transfer medium exits the evaporator at the outlet 16 and is sent to a body to be cooled, such as a building. In the embodiment of Figure 2, the cooled first liquid heat transfer medium cools the building or other body to be cooled. The refrigerant vapor exits the evaporator at arrow 4' and is sent to a compressor 7' where the vapor is compressed and exits as a high temperature, high pressure refrigerant vapor. This refrigerant vapor enters the condenser 5' via the condenser coil 10' at the crucible. The refrigerant vapor is cooled in the condenser by a second liquid heat transfer medium (e.g., water) to become a liquid. The second liquid heat transfer medium is passed to the condenser via the condenser heat transfer medium inlet 20. The second liquid heat transfer medium draws heat from the condensed refrigerant vapor that becomes the liquid refrigerant, which warms the second liquid heat transfer medium in the condenser. The second liquid heat transfer medium exits the condenser via the condenser heat transfer medium outlet 18. The condensed refrigerant liquid exits the condenser via a down-rotating tube 10' as shown in Figure 2 and flows through an expansion device 12, which may be an orifice, capillary or expansion valve.

Power Cycle The following definitions are particularly applicable to power cycles (eg, organic Rankine cycles: net cycle power output is the mechanical power production rate at the expander (eg, turbine) minus the mechanical power consumed by the compressor (eg, liquid pump). 44 201219349 _ —, the volume of the force cycle is the net cycle power output per unit volume of the working fluid circulating in the cycle (measured under the expansion member).

Accordingly, the present invention includes - -HF〇-l336mzz The composition of the 臓 236 236 is referred to as the working fluid in terms of heat return = method. Figure 3 illustrates an OC system: a schematic of an embodiment that utilizes heat from a heat source to generate mechanical 2 electric power. The exchanger 40 transfers the heat supplied by the heat source 46 to the working fluid of the 〇rc disk to enter the heat exchanger in a liquid phase. The heat exchanger 40 =·, , , and the source 46 are thermally connected. In other words, The exchanger 4 receives thermal energy from the heat source 46 by any means of transfer. The Rc system working fluid enters the heat recovery heat exchanger 4 in a liquid phase and circulates in the heat thereby obtaining heat. At least a portion of the liquid phase The recovery heat exchanger 40 (evaporator) is converted into a vapor. ..., the working fluid in the form of vapor is directed to the expander 32, which converts at least a portion of the thermal energy supplied by the scale 46 into mechanical shaft energy. Depending on the desired speed and job torque, the shaft can be used for any mechanical work by using belts, pulleys, gears, transmissions and the like. In one embodiment, the shaft can also be combined to produce an I-position such as induction. Motor 30. The generated power can be used locally or delivered to the grid. • wt 45 201219349 The working fluid leaving the expander still in vapor form continues to be directed to condenser 34 where sufficient heat is removed to allow fluid Condensation into a liquid. Ideally having a liquid buffer tank 36 between the condenser and the pump 38 to ensure that the working fluid of the liquid phase is sufficiently supplied to the pump suction port at all times. The working fluid of the liquid phase flows to the pump 38, The fluid pressure is increased so that the fluid can be directed back into the heat recovery heat exchanger, thereby completing the Rankine cycle loop. In another embodiment, a second heat exchange between the heat source and the ORC system can also be used. This configuration provides another means of removing heat from the heat source and transferring it to the ORC system. This configuration provides flexibility by facilitating the use of various fluids for sensible heat transfer. In fact, the present invention The working fluid can be used as the second heat exchange loop fluid if the pressure in the loop is maintained at a fluid saturation pressure greater than or equal to the fluid temperature in the loop. On the other hand, the working fluid of the present invention can be used as the second heat exchange. The loop fluid or the hot carrier fluid extracts heat from a heat source in the self-operating mode, wherein the working fluid can evaporate during the heat exchange process, thereby creating a large difference in fluid density sufficient to maintain fluid flow (thermosiphon effect). In addition, high boiling fluids such as glycols and salts thereof, polyfluorene oxide or other substantially non-volatile fluids may be used to effect sensible heat transfer in the second loop configuration described above. The second heat exchange loop makes maintenance of the heat source or ORC system easier because the two systems can be more easily isolated or separated. This approach simplifies heat exchanger design as compared to a heat exchanger having a high mass flow/low heat flux portion followed by a high heat flux/low mass flow portion.

Direct heat exchange in this form usually requires additional engineering and mechanical features' thus increasing costs. In this case, the temperature control is used, and the design of the second loop can promote the utilization of high-temperature heat sources while avoiding the problems caused by direct heat exchange. Other 〇Rc system components for the second heat exchange loop embodiment are substantially identical to those shown in FIG. The liquid pump 42 circulates the second body within the second loop to cause it to enter the loop portion of the heat source 46 to obtain heat therefrom. The fluid then passes through heat exchanger 40, while the second fluid delivers heat to the ORC working fluid.
