Description

Tray Nozzle of Absorption Chiller

[Technical field to which the design belongs]

The present invention relates to a tray nozzle of an absorption chiller and water heater using an absorbent liquid, and more particularly, is designed to be able to simply fix a nozzle without welding or other fixtures, and to improve its performance uniformly.

[Prior art]

Conventionally, the absorption chiller has a heating chamber 12 that is heated by a gas burner 11 by putting a lithium bromide (LiBr) solution, which is a low concentration absorbing liquid, as shown in FIG. 1, and the refrigerant (water) in the low concentration absorbing liquid. The high temperature regenerator 1 to vaporize (evaporate) to form a medium absorbent liquid, and the medium absorbent liquid is heated using the heat of condensation of the vaporized refrigerant in the high temperature regenerator 1, and the refrigerant contained in the medium absorbent liquid is vaporized into a high concentration absorbent liquid. A low temperature regenerator (2) and a condensation heat exchanger (31) through which coolant passes, cool the vaporized refrigerant (water vapor) separated from the high temperature regenerator (1) and the low temperature regenerator (2), and then cool the liquid refrigerant (water). The condenser 3 returned to the furnace, the evaporator 4 for evaporating the liquid refrigerant liquefied in the condenser 3 under vacuum, the absorption heat exchanger 34 through which the cooling water passes, and the evaporator 4 is evaporated. A vaporized refrigerant is obtained from the low temperature regenerator (2). It is equipped with the absorber 5 which absorbs a true high temperature absorption liquid.

Then, the concentrated solution of the low temperature regenerator 2 is uniformly dispersed in the absorption heat exchanger 34 of the absorber 5 so as to absorb the heat exchanger 34 from the tray supply nozzle 100 disposed above. Sprayed up.

On the other hand, the liquid refrigerant supplied from the condenser (3) is uniformly scattered on the heat exchanger (33) of the evaporator (4) by the tray nozzle (100), the liquid scattered on the absorption heat exchanger (34). The refrigerant (water) evaporates by taking the heat of vaporization from the heat medium flowing through the evaporation heat exchanger (33).

As a result, the heat medium (cold / hot water) flowing in the heat exchanger 33 for evaporation is cooled and guided into the indoor heat exchanger 7 to exchange heat with air starting to blow into the room to cool the room.

In this way, a plurality of tray nozzles 100 for supplying a solution and a refrigerant are installed at regular intervals. Conventionally, the installation structure of the tray nozzles 100 is mainly fixed by fixing a fixture by spot welding.

As described above, when the tray nozzle 100 is indirectly fixed to other process materials by the reception in the conventional absorption type cold and hot water machine, since the installation quantity of the tray nozzle 100 is very large, the time required for spot welding is large.

In addition, deformation is applied due to inferior heat applied to the tray nozzle 100 at the time of spot welding, thereby inevitably reducing performance.

In particular, in the case of a compact absorption chiller, the diameter of the tray is so small that the close contact after the insertion of the tray nozzle 100 makes it difficult to maintain performance.

[Purpose of designation]

The present invention is to provide an absorption cold and hot water heater so that the installation of the tray nozzle can be made simple.

Another object of the present invention is to provide an absorption cold and hot water heater that can be installed without reducing its performance.

Another object of the present invention is to provide an absorption cold and hot water heater, which can be installed in a particularly small tray.

EXAMPLE

Hereinafter, a preferred embodiment of the present invention will be described.

1 shows an apparatus diagram of an absorption chiller.

2 to 7 illustrate the configuration of the tray nozzle 100.

According to the structure of the absorption type cold / hot water machine shown in FIG. 1, the heating chamber 12 is put in a low concentration absorption liquid (lithium bromide aqueous solution in this embodiment), and is heated by the gas burner 11.

The high temperature regenerator 1 vaporizes (evaporates) the refrigerant (water) in the low concentration absorption liquid to form a medium concentration absorption liquid.

The low temperature regenerator 2 uses the heat of condensation of the vaporized refrigerant in the high temperature regenerator 1 to heat the medium absorbent liquid and vaporize the refrigerant contained in the medium absorbent liquid so that the high concentration absorbent liquid is generated.

The condenser 3 includes a heat exchanger 31 for condensation through which cooling water passes, and cools the vaporized refrigerant (water vapor) separated from the high temperature regenerator 1 and the low temperature regenerator 2 and returns it to the liquid refrigerant.

The evaporator 4 then evaporates the condenser 3 and the liquid refrigerant liquefied by the condenser 3 under vacuum.

The absorber 5 arranges the absorption heat exchanger 34 through which the cooling water passes, and absorbs the vaporized refrigerant evaporated in the evaporator 4 into the high temperature absorbing liquid obtained from the low temperature regenerator 2.

Therefore, by evaporating the liquefied refrigerant (water) in the evaporator 4, the heat medium (cold / hot water) passing through the evaporator 4 is cooled, and the cooled heat medium is indoors in the indoor heat exchanger 7 arranged indoors. Cool the room by exchanging heat with air that starts to blow. The heat medium whose temperature rose after heat exchange is cooled in the evaporator 4 again.

The vaporized refrigerant (water vapor) evaporated in the evaporator 4 is absorbed by the absorber 5 in the high concentration absorbent liquid.

At this time, heat of absorption occurs and the temperature of the absorption liquid rises.

Thus, to absorb the heat of absorption and increase the absorption capacity of the high concentration absorbent liquid supplied to the absorber 5, the absorber 5 is provided with an absorption heat exchanger 34 and cooling water is supplied.

In the condenser 3, a condensation heat exchanger 31 for liquefying vaporized refrigerant (water vapor) generated in the low temperature regenerator 2 is wound in a coil form, and cooling water passing through the absorption heat exchanger 34 passes.

Then, the cooling water whose temperature rises through the absorber 5 and the condenser 3 is cooled by water cooling or air cooling and supplied to the absorber 5 and the condenser 3 again, and the heat of gas combustion of the gas burner 11 is increased. The low concentration absorbent liquid is heated.

The low concentration absorbent liquid boiling in the heating chamber 12 starts to move to the high temperature regenerator 1 together with the vaporized refrigerant (water vapor).

The high temperature low concentration absorbent liquid that has started to move into the high temperature regenerator 1 is concentrated to become a medium concentration absorbent liquid.

The low temperature heat exchanger 21 exchanges heat between the high concentration absorbent liquid flowing from the low temperature regenerator 2 to the absorber 5 and the low concentration absorbent liquid flowing from the absorber 5 to the heating chamber 12. The high concentration absorbent solution flowing in (5) is cooled, and the low concentration absorbent liquid flowing from the absorber 5 to the heating chamber 12 is heated.

The high temperature heat exchanger 15 is provided in series with the low temperature heat exchanger 21.

On the other hand, the low temperature regenerator 2 injects the medium absorbent liquid toward the upper part of the high temperature regenerator 1.

Since the temperature in the low temperature regeneration container 2 is lower than the temperature of the high temperature regenerator 1, the pressure in the low temperature regenerator 2 is lower than the pressure of the high temperature regenerator 1.

For this reason, the medium concentration absorbent liquid supplied into the low temperature regeneration container 2 is easily evaporated, and the medium concentration absorbent liquid is injected into the upper portion of the low temperature regeneration container 2. Heats and the liquid refrigerant (water) evaporates, so the medium absorbent liquid becomes a high concentration absorbent liquid.

At this time, the vaporized refrigerant (water vapor) evaporated in the low temperature regenerator (2) is supplied into the condenser (3).

On the other hand, the high concentration absorbent liquid falls to the lower part of the low temperature regeneration container 2 and is supplied to the absorber 5 through the high concentration absorbent liquid pipe connected to the lower part of the low temperature regenerator 2.

The condenser 3 is provided with a condensation heat exchanger 31 for cooling and liquefying vaporized refrigerant (steam).

The heat exchanger 31 for condensation is an annular coil, and cooling water flows in the tube.

The vaporized refrigerant (water vapor) supplied from the low temperature regenerator 2 into the condenser 3 is cooled by the heat exchanger 31 for condensation to become a liquid refrigerant (water).

In the condenser (3), the liquid refrigerant is boiled again through the piping in the high temperature regenerator (1) to the pressure difference (low pressure of 70 mmHg in the condenser), and in the condenser (3) vaporized refrigerant (water vapor) and liquid refrigerant (water) Is in a mixed state.

In addition, the refrigerant condenser for connecting the liquid refrigerant to the evaporator 4 is connected to the condenser 3 so that the liquid refrigerant (water) is supplied from the condensation vessel 3 to the evaporator 4 while the valve is open.

The evaporator 4 includes an annular vessel-shaped evaporative absorption vessel 50 which is provided in the lower portion of the condenser 3 together with the absorber 5 and arranged around the regenerator 2.

An evaporation heat exchanger 33 for evaporating the liquid refrigerant (water) supplied from the condenser 3 is disposed outside the evaporation absorption container 50. The evaporation heat exchanger 33 is an annular coil, and the heat medium (cold / hot water) supplied to the internal heat exchanger 7 flows in the tube.

Then, the liquid refrigerant (water) supplied from the condenser 3 through the refrigerant pipe is transferred from the liquid refrigerant tray nozzle 100 disposed above the evaporation heat exchanger 33 to the evaporation heat exchanger 33. Scattered.

Since the boiling point is low in the evaporation absorbing vessel 50 and maintained in a vacuum (about 6.5 mmHg), the liquid refrigerant (water) scattered on the evaporation heat exchanger 33 is very easily evaporated.

Then, the liquid refrigerant (water) scattered on the evaporation heat exchanger 33 evaporates the heat of vaporization from the heat medium flowing through the evaporation heat exchanger 33. As a result, the heat medium (cold / hot water) which flows in the evaporation heat exchanger 33 is cooled.

Then, the cooled heat medium is guided into the indoor heat exchanger (7) to heat exchange with air that starts to blow into the room to cool the room.

Then, the concentrated solution of the low temperature regenerator 2 is uniformly dispersed in the absorption heat exchanger 34 of the absorber 5 to the absorption heat exchanger 34 from the solution supply tray nozzle 100 disposed above. Will be scattered.

2 illustrates a tray nozzle 100 of the present invention in a perspective view.

That is, the pinching blades 101 are symmetrically formed on both sides so that the upper side is caught by the skirt 110 installed in a ring shape having a thin cross section at the lower side of the tray, and the liquid refrigerant is guided from the rear tray to fall downward. It is shaped to have a passageway 102.

In this case, the hole 103 is drilled out of the tray in the induction path 102, and according to the size of the hole 103, the moving speed of the refrigerant induced along the induction path 102 can be adjusted differently.

4 is a longitudinal cross-sectional view of the tray nozzle 100 is installed in the skirt 110, the inlet of the induction passage 102 is installed in a state in which the solution is immersed in the solution by the pressure difference induction passage 102 It is shown to fall slightly after entering the following.

In this case, the tray nozzle 100 may be fixed even when the tray is folded over by folding the lower end of the tray nozzle 100 into the tray apparatus.

On the other hand, Figure 5 shows another embodiment of Figure 4, by cutting a portion of the lower side of the pinch wing 101 and wound to the inside of the skirt 110 to form the holder portion 104 from the upper and lower sides It is shown to be firmly fixed to the skirt 110 to be in close contact with the tray device.

According to the configuration of the present invention as described above, the tray nozzle 100 can be more firmly fixed and installed without the work of spot welding more simply.

Therefore, production cost can be reduced.

In addition, it is a very useful design, such as to be able to maintain uniformly without degrading the performance of the tray nozzle (100).
