Description

New refrigerant gas composition and preparation method thereof

Embodiment of the present invention relates to a new refrigerant gas composition and a method for manufacturing the same, and more specifically, it can lower the pressure compared to the conventional refrigerant gas (R410A), while maintaining the appropriate room temperature during heating and cooling conventional refrigerant gas (R410A) is to save more than when injected, which greatly improves the quality and reliability of the product to meet the various needs (customers) of consumers, users can be planted a good image. In addition, it is a technology that can greatly contribute to the reduction of carbon dioxide emission, which is currently issued globally.

As is well known, gases such as ammonia, methyl chloride, and propane were used as coolants in early air conditioners and refrigerators. Toxic and flammable gases were dangerous when leaked and were accidental. In the 1920s, Freon developed a safe human body, but later it was discovered that freon destroys the ozone layer in the atmosphere. The most commonly used refrigerant in air conditioners is HCFC, also known as R-22, which also destroys the ozone layer. The R-22 is expected to be completely banned in 2030 in Korea because it restricts production and import until 2013.

In other words, EC Regulation No 1005/2009, the European Parliament and the September 16, 2009 Committee on Ozone Depleting Substances, confirmed that ozone depleting substances (ODS) cause serious damage to the ozone layer. However, the level of concentration of ozone recovery has remained before 1980 and is now expected to take place before the mid-21st century. Increased UV-B radiation due to ozone layer destruction therefore persists as a major threat to health and the environment. At the same time, most of these substances are acting as factors of temperature rise and global warming. Chlorofluorocarbons, halogenated chlorofluorocarbons (freon gas), halons, carbon tetrachloride, 1,1,1-trichloroethane, hydroblomofluorocarbons, blomochloromethane and methyl bromide were phased out and produced And batches, marketplaces of these materials and equipment containing those materials forbidding the product. It is gradually a trend to generalize the ban on the use of such materials for the maintenance or service of such equipment.

On the other hand, cool air requires the price of electrical energy. As such, air conditioners transfer thermal energy from low to high temperatures. There is something strange about this. Just as the spoon in a hot soup gets hot, the thermal energy is moving from high to low temperature. The heat engine gets heat energy from a hot heat source and spins the wheels. Some of the heat flows to a low temperature by itself. No matter how well designed the engine is, it is impossible to create a heat engine that converts a given heat to 100% work. This is the second law of thermodynamics. This means that there is an irreversible process in nature. Air conditioning, a representative heat pump that transfers thermal energy from low to high temperatures, seems to be contrary to the second law of thermodynamics. But air conditioners only operate when they consume electrical energy. In other words, more energy is consumed to transfer thermal energy from low temperature to high temperature, so that the entropy of the whole system increases, which eventually satisfies the second law of thermodynamics. Considering that a summer without air conditioners is unthinkable, considering that cool air is not given by itself, reducing the power consumption of air conditioners is a goal for the nation and the individual, and the amount of power reserves from air conditioners is a form of emergency. As a result, the reduction of power consumption of air conditioners due to the development of new refrigerants is a national problem, but in the related art, there is a problem in that new refrigerants cannot be developed due to technical difficulties.

On the other hand, the refrigerant gas injected into the current inverter type air conditioner is R410A gas, and when the R410A gas is injected into the inverter type air conditioner to operate, the room temperature is the lowest degree Celsius. The air conditioner was designed and manufactured to maintain 18 degrees and up to 30 degrees Celsius.However, if the proper room temperature is set due to the characteristics of the inverter, the inverter sets the operating speed of the compressor. Rise linearly until the temperature is reached to reach the appropriate room temperature, and then maintain the room temperature while varying the operating speed of the compressor. At this time, the operating speed of the compressor (compressor) does not generate the maximum speed and the maximum torque (torque), and controls the discharge air volume while operating at 70% or less of its own capacity, that is, the maximum air conditioner (air con) maximum output. However, at this time, the driving current of the air conditioner (air con) is maintained unnecessarily and excessively, which does not decrease much due to the characteristics of the R410A GAS, which acts as a loss such as driving an unnecessary load in a luggage compartment when viewed by a car.

In order to solve the above problems, the following prior art documents have been developed, but still pointed out as a big problem that does not solve the above problems at once.

Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention for achieving this effect are as follows.

1 is a photograph under test applying a new refrigerant gas composition applied to the present invention air conditioner.

New refrigerant gas composition and a method of manufacturing the same applied to the present invention is configured as shown in FIG.

In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The following terms are terms set in consideration of functions in the present invention, which may vary depending on the intention or custom of the producer, and their definitions should be made based on the contents throughout the specification.

In addition, since the size and thickness of each component shown in the drawings are arbitrarily shown for convenience of description, the present invention is not necessarily limited to those shown in the drawings.

First, the present invention provides a new refrigerant gas to reduce power consumption while maintaining a proper room temperature during heating and cooling, the new refrigerant gas is composed of the following composition.

That is, the present invention provides a new refrigerant gas composition in which difluoroethane, pentafluoroethane, tetrafluoroethane and trifluoroethane are mixed with each other.

At this time, the difluoroethane (difluoroethane) applied to the present invention is 3.1 ~ 6.9% by weight (wt%). Pentafluoroethane is 3.1 to 4.9 wt% (wt%), tetrafluoroethane is 88 to 89 wt% (wt%), and trifluoroethane is 2-3 wt% ( wt%)) is preferred.

The reason for numerical limitation of the present invention will be described in more detail as follows.

First, when the difluoroethane and pentafluoroethane are less than 3.1 wt% (wt%), the discharge air temperature of the air conditioner is 14 degrees Celsius or more when cooling, and when heating It is preferable that the above-mentioned difluoroethane and pentafluoroethane are 3.1 wt% or more (wt%) because they are inefficient due to relatively low 40 degrees Celsius or less.

When the difluoroethane and pentafluoroethane are more than 6.9 wt% (wt%) and 4.9 wt% (wt%), respectively, the specific gravity of the refrigerant is increased so that the inverter is set to the room temperature setting value. Therefore, the difluoroethane and pentafluoroethane are 6.9 wt% (wt%) and 4.9, respectively, because they are not suitable for actively adjusting the speed and thus only burden the compressor and waste power. Preference is given to weight% (wt%) or less.

In addition, when the tetrafluoroethane (tetrafluoroethane) applied to the present invention is 88% by weight (wt%) or less, since the pressure of the refrigerant increases and the burden of the compressor increases, the role and capability of the inverter decreases. (tetrafluoroethane) should be at least 88% by weight (wt%),

When the tetrafluoroethane is more than 89% by weight (wt%), the efficiency of the refrigerant decreases and the coolant action is weakened, so that the proper discharge temperature of the air conditioner cannot be maintained. The tetrafluoroethane is preferably 89% by weight (wt%) or less.

In addition, trifluoroethane applied to the present invention is a very powerful refrigerant as a catalyst, and when its content is less than 2% by weight (wt%), the heating and cooling ability is lowered, so trifluoroethane (trifluoroethane) is At least 2% by weight (wt%),

When the trifluoroethane is more than 3% by weight (wt%), the capacity is increased, but the discharge temperature and the refrigerant pressure characteristics are not matched properly for operation in an inverter type, and thus the energy saving effect is reduced. Ortho (trifluoroethane) is preferably 3% by weight (wt%) or less.

On the other hand, the present invention may be variously modified and may take various forms in applying the above configuration.

And it is to be understood that the invention is not limited to the specific forms referred to in the above description, but rather includes all modifications, equivalents and substitutions within the spirit and scope of the invention as defined by the appended claims. It should be understood that.

Referring to the operation and effect of the present invention the new refrigerant gas composition and the manufacturing method configured as described above are as follows.

First, the present invention can reduce the pressure compared to the conventional refrigerant gas (R410A), and to reduce the power consumption compared to the conventional refrigerant gas (R410A) while maintaining the appropriate room temperature during heating and cooling.

To this end, the present invention breaks the contradiction of applying the same type of performance test method applied to the inverter type air con as it is to the inverter type air con instead of the inverter type air conditioner. An energy saving type inverter type air con. We have developed a new refrigerant gas that is optimized for air conditioning, reducing air conditioning power consumption by up to 60% when cooling and up to 40% when heating, thereby reducing global CO2 emissions and reducing heating and cooling power, which accounts for more than 20% of global power consumption. To contribute to energy savings.

A first mixing process of mixing 3.1 to 6.9% by weight of difluoroethane (wt%) and 3.1 to 4.9% by weight of pentafluoroethane (wt%) is performed.

Then, the present invention undergoes a second mixing process of mixing 88-89% by weight (wt%) of tetrafluoroethane to materials mixed by the first mixing process.

Subsequently, the present invention is to prepare a new refrigerant gas composition through a third mixing process of mixing 2-3 wt% (wt%) of trifluoroethane to the material mixed by the second mixing process.

At this time, the first mixing process, the second mixing process and the third mixing process,

The first mixing process, the second mixing process, and the third mixing process are preferably prepared by mixing the low-pressure gas into the container first so that the materials are well diluted with each other and the gas is stabilized. .
