関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a refrigeration fluid composition consisting of a single or a mixture of carbon atoms having 1 to 20 carbon atoms, which has a watertight, airtight capacity of 1 g, and can be detected immediately if it leaks from a pipe or the like. It is about things.
周知のようにフルオロカーボンは、無色、無臭。As is well known, fluorocarbons are colorless and odorless.

しかし、上記無色、無臭の物性を有するため。Non-toxic, safe to handle, and has a low freezing point.
O has various boiling points depending on the species, and is widely used as a refrigerant in various types of refrigerators and refrigerators. However, it has the above-mentioned colorless and odorless physical properties.

所期の効果は十分発揮していないのが現状であＡ。Especially if the refrigerator is installed in a basement, etc., the vapor density of fluorocarbon is high, so it accumulates indoors.
Accidents may occur where a person who enters without paying attention to the leak may fall down due to a sickle. As a countermeasure against such accidents, a dye is mixed with the refrigeration fluid made of fluorocarbon, and when a leak occurs, the leaked area is colored with the dye, making it possible to detect the leak early. If a leak occurs in the liquid phase of a device, the fluorocarbon will be noticeable because it will color the leaked area, but if a leak occurs in the gas phase, there will be no dye in the gas phase. No leaks can be detected. In addition, since the main parts of these devices are usually covered with cold insulation material, the coloring caused by the dye is not visible from the outside, making early detection of leaks difficult.
The current situation is that the expected effects are not being fully achieved.

重量搭添加したガス漏れ検知可能なフルオロカーボン冷
凍作用流体組成物を得ることに成功したものである。In view of the above circumstances, it is an object of the present invention to provide a refrigeration fluid composition consisting of fluorine and carbon that can easily detect leakage. In order to achieve this goal, extensive research has shown that ammonia is stable against fluorocarbons, and when contained in small amounts, the composition is inert to steel and copper-based materials, and is highly effective against fluorocarbons. It was found that it did not affect the performance as a refrigerant. The present invention is based on this knowledge, and ammonia f: aooiNs
It has been successfully achieved that a gravimetrically loaded fluorocarbon refrigeration fluid composition is capable of detecting gas leaks.

れも、早期に知ることが出来る。Ammonia is a gas at normal temperature and pressure, and ammonia coexists regardless of whether the fluorocarbon to which ammonia is added is in a gas phase or a liquid phase. Therefore, in the event of a leak,
Its presence is easily detected by the pungent odor characteristic of ammonia gas. The human sense of smell for ammonia has an extremely low detection limit of jppm, making it possible to detect leaks of extremely small amounts of O refrigeration fluid at an early stage.
以下に実施例を示し本発明を具体的に説明する。EXAMPLES The present invention will be specifically explained below with reference to Examples.

jg was added and the mixture was shaken and stirred. After leaving this for one day, the cylinder was first stood upright, then the cylinder was shaken up to take out the gas phase and liquid phase O Freon 12.
The mixture was discharged into the room at a rate of C/hour, and the time for the odor to be detected by the sense of smell was measured at a position approximately 2 vs. from the discharge port. As a result, a clear ammonia odor was detected within 3 to S minutes even when the gas phase and liquid phase were out of □.

合と比較して冷却能力に差は認められなかった。Example A small amount of refrigerant from a refrigerator using Daflon 12 as refrigerant was extracted,
Operation was performed with the addition of ammonia IJLJ9 (approximately equivalent to standard weight attack). After 50 days, this refrigerant was extracted and the amount of ammonia present was measured by absorption, and it was found that the amount matched with the amount added, indicating that no chemical changes had occurred. In addition, no difference was observed in the cooling capacity of the refrigerator during operation compared to when only Freon 12 was used as a refrigerant.〇Example! 1. Add a predetermined amount of ammonia to a room cooler filled with Freon 22. After SO operation for one day, the amount of ammonia was measured and it was confirmed that there was no change in the amount due to chemical changes. Also, during this period, no difference in cooling capacity was observed compared to when using only the refrigerant alone.

ことが出来る等価れた性能を有Ｔるものである。As described above, the refrigeration fluid composition according to the present invention has colorless and odorless fluorocarbons whose presence is detected even in trace amounts due to their strong pungent odor, and which has a high performance as a refrigerant or refrigeration oil. Since it contains ammonia, which has no effect, it has equivalent performance in detecting and dealing with leakage of the refrigeration fluid made of fluorocarbon at an early stage.
