2. Description of the Related Art In an air conditioner such as an air conditioner and a freezing / refrigerating device such as a showcase for food display, a refrigerant which is a substance for operating a refrigeration cycle is filled in a refrigerant circulation circuit. In a factory that manufactures such devices as air conditioning, freezing, refrigeration, etc., the refrigerant liquid is stored in a large refrigerant liquid storage tank, and the refrigerant liquid is sent from the refrigerant liquid storage tank to a refrigerant supply device at a product manufacturing site. The refrigerant supply device fills the refrigerant circuit of these devices with the refrigerant.

By the way, chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC), when released into the atmosphere, destroy the ozone layer in the stratosphere. It is decided that its use will be limited and will be abolished in the future. Therefore, refrigerants mainly based on hydrofluorocarbon (HFC) have begun to be used as a substitute for chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC).

[0004] This hydrofluorocarbon (HFC)
Does not exhibit high refrigerant performance as a single refrigerant like chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), and is usually formed by mixing a plurality of hydrofluorocarbons (HFCs) to form a refrigerant mixture. Improving performance.

Non-azeotropic refrigerant liquids such as R400s such as -tetrafluoroethane (HFC-134a) (a 52% by mass mixed refrigerant). Further, according to the ASHRAE standard, each non-azeotropic refrigerant liquid has a refrigerant component of ± 10% of the standard.
There is a requirement that it be contained within the range of 2%. On the other hand, the non-azeotropic refrigerant liquid has a characteristic that the composition ratio of the refrigerant component constituting the refrigerant liquid is easy to change because the low-boiling refrigerant component evaporates more easily than the high-boiling refrigerant component. .

Therefore, in an air-conditioning, freezing, refrigeration, etc. apparatus using a mixed refrigerant, the composition ratio of the refrigerant component constituting the filled refrigerant liquid due to leakage of the refrigerant to the outside of the apparatus is an allowable composition. It may deviate from the specific range.

The composition of the processing refrigerant on the discharge side is obtained by calculation, and a method of replenishing a mixed refrigerant is disclosed which determines and replenishes the composition of the refrigerant to be replenished in the system from the difference from a predetermined composition. According to the description, it is economical because the composition of the refrigerant to be replenished can be determined from the flow rate, pressure, and temperature that can be easily measured without using composition analysis.

Further, there is disclosed a refrigerant filled with a low-boiling-point refrigerant at a ratio higher than a predetermined composition ratio. Since the apparatus is filled with a low-boiling-point refrigerant at a higher ratio than the ratio initially charged, the ratio of the mixed refrigerant after the filling can be made closer to the initial ratio,
Is described.

Further, there is a possibility that the refrigerant liquid whose composition ratio of the refrigerant component deviates from the allowable composition ratio range may be filled in the refrigerant circuit of the apparatus product.

A method for filling a liquefied gas that is pressurized with a liquefied gas or a compressed gas having a low boiling point from the vapor side of the first container when transferring and filling is disclosed. According to such a configuration, a working fluid for a vapor compression refrigeration cycle is disclosed. It is described that the change in the composition ratio that occurs when the non-azeotropic mixed refrigerant used is transferred and filled can be significantly reduced, and that the deterioration of the refrigerant performance and the increase in the danger of combustion can be prevented. ing.

According to such a configuration, a drive mechanism that closes regardless of the detection position of a liquid level detector is disclosed. According to such a configuration, a refrigerant is sealed in an air conditioner or the like from a refrigerant charging cylinder filled with a non-azeotropic mixed refrigerant. In this case, since the supply / exhaust port inlet is opened only when the liquid refrigerant is used, it is possible to seal the refrigerant having a predetermined composition without accidentally enclosing the gas refrigerant in an air conditioner or the like.

Further, as described above, in a factory that manufactures equipment for air conditioning, freezing, refrigeration, etc., refrigerant liquid is usually stored in a large refrigerant liquid storage tank. As the refrigerant liquid stored in the refrigerant liquid is consumed, the gas phase region in the refrigerant liquid storage tank increases and the pressure in the tank changes, so that the composition ratio of the refrigerant component deviates from the allowable composition ratio range. It may change. Further, the composition ratio of the refrigerant component constituting the refrigerant liquid in the refrigerant liquid storage tank when the refrigerant liquid in the refrigerant liquid storage tank is replenished from the container vehicle or lorry to the refrigerant liquid storage tank when the refrigerant liquid is slightly leaked from the refrigerant supply device at the product manufacturing site. Due to the slight deviation between the composition ratio of the refrigerant liquid in the tank of the container vehicle or the lorry and the refrigerant component in the refrigerant liquid storage tank, the refrigerant component in the refrigerant liquid storage tank has an allowable composition ratio range. It can be out of order.

If such an abnormal refrigerant is charged into a product device without detecting such a situation, the product device cannot not only exhibit a predetermined ability but also seek the cause of producing such a defective product. Production activities will be delayed, for example, the production line must be stopped.

All of 57 are closed, the circulation pump 32 is stopped, and the first and second vacuum pumps 33 are operated. At this time, the circulation of the refrigerant liquid in the refrigerant liquid circulation path 22 is stopped, and the refrigerant for the composition ratio detection is placed in the measuring pipe 16 provided between the first valve 51 and the second valve 52 in the refrigerant liquid circulation path 22. The liquid sample is trapped. In addition, by operating the first and second vacuum pumps 33, the first and second vacuum pump paths 24 and 25 are maintained in a vacuum state in advance. Here, in order to maintain the first and second vacuum pump paths 24 and 25 at a high degree of vacuum,
It is preferable to start the first and second vacuum pumps 33 10 to 15 minutes before the start of sampling.

Next, the fourth and sixth valves 54 and 56 are opened and the other valves are closed. At this time, a portion between the second valve 52 and the third valve 53 in the refrigerant liquid circulation path 22,
And the fifth valve 55 and the seventh valve 5 in the sampling path 23
7 is evacuated by the first and second vacuum pumps 33 to be in a vacuum state. Thus, when a sample of the refrigerant liquid is introduced into the sampling path 23, foreign matter is prevented from being mixed into the sample.

Next, all of the first to seventh valves 51 to 57 are closed. Thereby, the vacuum state of the part between the second valve 52 and the third valve 53 in the refrigerant liquid circulation path 22 and the part between the fifth valve 55 and the seventh valve 57 in the sampling path 23 are maintained. .

Then, the second and fifth valves 52 and 55 are opened and the other valves are closed, and the sample vaporizing container 17 is heated by the heater. At this time, the sample of the refrigerant liquid confined in the measuring pipe 16 flows into the decompressed sampling path 23 and is vaporized in the sample vaporization container 17.

Next, when the seventh valve 57 is opened, the second, fifth and seventh valves 52, 55, 57 are opened and the other valves are closed. At this time, a predetermined amount of the vaporized refrigerant sample is stored in the gas sampler 19, and is pushed out by a helium gas supplied from a helium gas pipe (not shown) connected to the gas sampler 19, so that the composition ratio detection device 12 (gas chroma (Tograph) column 12a.

The composition ratio (mass ratio) of the refrigerant component constituting the refrigerant liquid in the refrigerant liquid storage tank 11 is detected for a sample of the refrigerant flowing into the column 12a, and the result of the detection is the composition ratio data. The information is transmitted from the processing unit 12b to the information transmission device 15 via the composition ratio information transmission path 41 as information. At the same time, the second, fourth and sixth valves 52, 5
4, 56 are open and the other valves are closed. At this time, the first valve 51 and the third valve 5 in the refrigerant liquid circulation path 22
3 and the fifth in the sampling path 23
The portion between the valve 55 and the seventh valve 57 is evacuated and evacuated by the first and second vacuum pumps 33, and the refrigerant liquid or the vaporized refrigerant remaining in these portions is removed.

Next, by closing the fourth and sixth valves 54 and 56, only the second valve 52 is opened and the other valves are closed. Thus, the preparation for circulating the refrigerant liquid in the refrigerant liquid circulation path 22 is completed.

Next, by opening the first and second valves 51 and 52, the first to third valves 51 to 53 are opened and the fourth
-7 valves 54-57 are closed, the circulating pump 32 is started and the first and second vacuum pumps 33 are stopped, and the refrigerant liquid is

The change in the liquid level is detected as a pressure difference by the differential pressure gauge of the stored amount detecting device 13, and the detected value is detected by being converted into the mass of the refrigerant liquid by a predetermined formula in the stored amount data processing unit. The detected storage amount is transmitted from the storage amount data processing unit to the information transmission device 15 via the storage amount information transmission path 42 as information.
