Definitions
- the present invention relates to a full liquid evaporator having a good heat transfer effect by utilizing a good heat transfer action of a liquid among the evaporators incorporated in a refrigerator or the like, and further improves the heat transfer effect.
- the present invention relates to a full-liquid evaporator that improves the separation function of the refrigerant liquid mist contained in the refrigerant vapor evaporated from the refrigerant liquid.
- a full liquid evaporator fills an evaporator with a refrigerant liquid, arranges a tube through which the medium to be cooled flows, and exchanges heat between the refrigerant liquid and the medium to be cooled (cooling water or the like).
- This is an evaporator that cools the medium to be cooled by removing the latent heat of vaporization of the refrigerant liquid from the medium to be cooled, and has a good heat transfer effect with the liquid.
- Patent Document 1 discloses that a bubble is positively brought into contact with each medium-cooled medium tube arranged in a shell in which a refrigerant liquid is stored, thereby utilizing the disturbance effect caused by the bubbles to cover the refrigerant liquid.
- Full liquid evaporation for the purpose of improving the heat transfer effect with the cooling medium and at the same time reducing the outflow of the refrigerant liquid mist to the outside and preventing the liquid back while sufficiently increasing the heat transfer coefficient.
- the configuration of the vessel is disclosed.
- FIG. 8 shows the configuration of the full-liquid evaporator, which is a full-scale evaporator including a cylindrical horizontal shell 01 for storing refrigerant liquid and a plurality of cooling tubes 02 piped inside the shell 01. Air bubbles in contact with the outlet piping 02c and 02d in the cooling tube 02, which are liquid evaporators A bubble increasing means 03 for increasing the amount and a liquid outflow reducing means 04 flowing out from the shell 01 are provided.
- the bubble increasing means 03 and the liquid outflow amount reducing means 04 are realized by the piping configuration of the path of the cooling tube 02, and the inlet 0 2a of the cooling tube 02 is connected to the upper layer of the liquid in the shell 01 and the inside of the shell 01.
- the second stage path 02b of the inlet path 02a is connected to the lower liquid layer part of the liquid, and the outlet paths 02c and 02d are connected to the liquid intermediate layer part in the shell 01, respectively.
- a refrigerant liquid inlet 05 is provided at the lower center of the longitudinal direction of the shell 01, and a refrigerant vapor outlet 06 is provided at the upper part thereof.
- the liquid inlet 05 is a low-pressure refrigerant after compression, condensation, and expansion.
- the liquid a is introduced, and the low-pressure refrigerant vapor s evaporated inside the shell 01 is taken out from the gas outlet 06 and returned to the compressor.
- a flow dividing plate 07 having a large number of holes is arranged so that the liquid taken into the shell 01 can be uniformly opened in the longitudinal direction of the shell 01.
- the relatively high temperature of the medium b to be cooled flowing into the inlet tube 02a of the refrigerant tube 02 and the liquid upper layer in the shell 01 exchange heat, so that the refrigerant liquid a is gasified near the liquid level.
- the amount of liquid mist floating at the top of the liquid level is reduced, thereby preventing liquid back, and bubbles are generated around the tube 02b in the outlet tubes 02c and 02d that generate less bubbles.
- the amount of bubble generation is compensated for by the air bubbles that come to enhance the bubble agitation effect. While preventing liquid back by this bubble agitation effect, the heat transfer coefficient of the ridge part where the bubble agitation effect is small is improved and the heat transfer coefficient is increased as a whole.
- Patent Document 2 discloses a full-liquid double-pipe evaporator in which the apparatus configuration is compact and the carryover of the refrigerant liquid by the refrigerant vapor is suppressed.
- 9A and 9B are an elevation view and a cross-sectional view of the device.
- a full-liquid double-tube evaporator 011 is composed of an outer cylinder 013 and an inner cylinder 014, the cylinder axis direction is horizontal and the refrigerant liquid a flows between the outer cylinder 013 and the inner cylinder 014.
- the inside of the inner cylinder 014 is formed in the cooled medium chamber 017 through which the medium to be cooled b flows, and the side portions 016A and 016B of the refrigerant liquid chamber 016 formed on the left and right sides of the inner cylinder 014, respectively.

Minute: on the side in contact with the inner surface of the outer cylinder 013), the refrigerant liquid a descends and exchanges without interfering with each other. Therefore, mixing over stirring of the refrigerant vapor s and the refrigerant liquid a is prevented to suppress carryover. It is out.
- the distance from the inner cylinder 014 is short, so that a stable upward flow of the refrigerant vapor s occurs, and as a result, the refrigerant vapor s is generated.
- the refrigerant liquid a has a high water concentration, and the refrigerant liquid with the high water concentration is taken out from the refrigerant liquid outlet 020, thereby suppressing an increase in the water concentration in the refrigerant liquid. As the water concentration increases, the evaporation temperature of the refrigerant liquid a increases.
- the refrigerant liquid a has a higher moisture concentration as it gets closer to the refrigerant liquid outlet 020 due to the evaporation of the refrigerant liquid by the heat taken from the medium b to be cooled in the refrigerant liquid chamber 016, and cools as the moisture concentration increases.
- the evaporation temperature of the medium increases. Therefore, the outlet position of the cooled medium b and the outlet position of the refrigerant liquid a are reversed to form both flow paths in countercurrent, and the evaporation temperature of the refrigerant liquid a is close to the refrigerant liquid supply port 019. Therefore, the cooled medium b cooled well flows out from the cooled medium outlet 023 near the refrigerant liquid supply port 019.
- Patent Document 2 suppresses the water concentration in the refrigerant liquid and improves the cooling effect on the medium to be cooled b.

There is also a limit to the liquid back effect by such means. Separation with high accuracy cannot be obtained, and once the medium to be cooled is mixed into the refrigerant liquid, the medium power of the medium cannot be removed.
- the full liquid evaporator described in Patent Document 2 is configured so that a stable upward flow s of the refrigerant vapor surrounds the periphery of the medium to be cooled 017. Since the gas whose heat transfer action is inferior to that covers the medium to be cooled 017, the heat transfer effect between the refrigerant liquid a and the medium to be cooled b is naturally limited.

To do. Thereafter, the refrigerant vapor rises further and reaches a demister provided above the space, where refrigerant liquid mist mixed in the refrigerant vapor when passing through the demister is collected by collision. The refrigerant vapor separated from the refrigerant liquid mist is then sent to equipment such as a compressor connected downstream.
